Income Tax Liability

A foreign entity can operate in Sweden either as a sole proprietorship (natural person) or as a corporate entity (legal person). Foreign legal entities have limited tax liability in Sweden. This means they are taxed only on income derived from permanent establishments in Sweden. A permanent establishment refers to a fixed place of business through which the company operates wholly or in part.

Foreign individuals usually also have limited tax liability. However, once they settle or stay permanently in Sweden, they become fully tax liable, meaning they are taxed on all income, both from Swedish and foreign sources.

Entrepreneurs who do not reside or stay permanently in Sweden are taxed only on income generated from business activities carried out through a Swedish permanent establishment.

In some cases, tax liability may be removed or reduced under international tax treaties.

Population Registration (Folkbokföring)

The Swedish population register is a central system for recording residents in Sweden. It contains information on who lives in Sweden and where. Correct registration is crucial, as it affects many rights and obligations – including where a person is taxed.

The register also records civil status and other personal details. Normally, a person should be registered at their place of actual residence, defined as the location where they live on a daily basis.

Registration

A foreign company conducting business in Sweden – regardless of whether it is a legal or natural person – may become liable for:

  • VAT,
  • social security contributions,
  • and income tax.

In such cases, the company must contact the Swedish Tax Agency (Skatteverket) to register and obtain an F-tax certificate.

Instructions for completing the SKV 4632 form (in Swedish) are available on the Skatteverket website under “How to apply for business registration.”

Sole proprietors with a Swedish personal identity number (personnummer), as well as companies with an authorized representative who holds a personnummer, can apply for registration online at Verksamt.se – a joint platform managed by Skatteverket, Bolagsverket, and Tillväxtverket.

Other foreign companies must submit their application directly to the International Office of the Swedish Tax Agency.

As part of the registration process, Skatteverket assigns a unique Swedish identification number to the foreign entrepreneur:

  • For individuals, proof of identity (e.g., passport or ID card) is required.
  • For legal entities, a certificate of incorporation is needed, and the representative must show authorization to act on behalf of the company (i.e., power of attorney).

Before registering, foreign legal entities should contact Bolagsverket to check whether branch registration is required. If so, Bolagsverket will assign the identification number. Contact details are available on Bolagsverket’s website.

Preliminary Tax Return (PD)

Anyone with income subject to taxation in Sweden is required to pay preliminary tax during the income year. To calculate the amount, the business must submit a preliminary income tax return to the Swedish Tax Agency (Skatteverket).

Based on this return, Skatteverket estimates the amount of tax due and notifies the business of the monthly tax instalments.

In the year following the income year, the business must file a final income tax return, reporting its actual financial results. Skatteverket will then calculate the final tax amount and compare it to the preliminary payments:

  • If the company overpaid, it will receive a refund.
  • If it underpaid, it must pay the difference.

Foreign legal entities equivalent to Swedish limited companies pay income tax at a rate of 26.3% on taxable profits.

Sole proprietors (natural persons) usually pay both income tax and social security contributions (egenavgifter). Their monthly instalments include both components.

EU law and bilateral social security agreements may in some cases override or adjust the application of Swedish national rules.

Foreign partners in Swedish partnerships (handelsbolag or kommanditbolag) are liable to pay tax in Sweden only if the partnership has a permanent establishment in Sweden. In such cases, the partner must also submit a preliminary tax return to determine monthly tax instalments.

A foreign entrepreneur applying for an F-tax certificate must file a preliminary income tax return, regardless of whether they have a permanent establishment in Sweden or not.

It is possible to update the information provided at any time during the year by submitting a new preliminary return. Skatteverket will then recalculate the monthly instalments. Relevant forms include SKV 4313, SKV 4314, and SKV 4315.

Annual Income Tax Return

A foreign business that is subject to Swedish tax on its commercial activities is obligated to file an annual income tax return.

  • Foreign legal entities typically must submit their tax return no later than May 2 of the year following the income year.
  • Foreign individuals must submit their tax return no later than May 31 of the following year.

More information is available in the Swedish Tax Agency’s brochures “Bokföring, bokslut och deklaration”, parts 1 and 2 (SKV 282 and SKV 283).

1) Wages for Work Performed in Sweden

Whether social security contributions must be paid in Sweden depends on:

  • EU law,
  • bilateral social security agreements, and
  • Swedish national law.

International agreements take precedence over Swedish law, and within the EEA, EU law generally prevails.

If a company pays wages for work performed in Sweden, it is generally required to pay Swedish social security contributions (arbetsgivaravgifter). If the company also has a permanent establishment in Sweden, it must:

  • pay preliminary income tax, and
  • register as an employer with Skatteverket.

This also applies to wages or remuneration paid to shareholders for work performed on behalf of their own company.

A foreign company with a permanent establishment is treated as a Swedish employer for purposes of social security contributions and income tax withholdings.

2) Social Security Contributions

Anyone who pays wages for work is required to pay social security contributions. The amount is based on the total salary and benefits paid.

A foreign company must pay contributions for work performed in Sweden regardless of whether it has a permanent establishment, except in certain short-term cases.

Under Swedish law, foreign employers without a permanent establishment are not required to pay social security contributions if:

  • the employee was posted for less than one year,
  • and meets other conditions under EU or bilateral social security rules.

If an employee resides in an EU/EEA country and is posted to Sweden for less than 24 months, and is not replacing someone previously posted, they may remain under their home country’s social security system.

In such cases, no Swedish social contributions are required. The employee must hold an A1 certificate (previously E101) proving social security coverage in their home country. In Sweden, A1 certificates are issued by Försäkringskassan. Employers should always request and keep a copy of the certificate.

Even when hiring a self-employed contractor, a foreign business might be liable for social contributions. However, if the contractor provides a valid F-tax certificate, the company is exempt.

A foreign company without a permanent establishment may agree with an employee that the employee will take responsibility for paying the social contributions. This agreement can be oral, but for legal clarity, a written agreement is strongly recommended.

  • The agreement should be submitted to Försäkringskassan.
  • The employee must also submit a preliminary tax return to Skatteverket to calculate monthly income tax and social contributions (known as SA tax, or SA-skatt).
  • This arrangement must also be declared in the employee’s annual income tax return.

Regardless of any such agreement, the foreign company must file an annual income report (kontrolluppgift) for the wages paid.

The rate of social contributions depends on the employee’s age and whether the company has a permanent establishment in Sweden. Foreign employers without a permanent establishment do not pay the general payroll fee (allmän löneavgift).

3) Preliminary Income Tax Withholdings

A foreign company with a permanent establishment in Sweden must withhold preliminary income tax on wages paid to employees.

For employees who are tax residents in Sweden, the applicable tax rates are listed in Skatteverket’s tax tables (skattetabeller).

Short-Term Stays: Less than 6 Months

If the employee stays in Sweden for less than six months, they may be subject to the SINK tax (Special Income Tax for Non-Residents). In this case:

  • The employer must withhold 25% of the gross salary as tax.
  • To apply the SINK rules, either the employee or employer must submit an application to Skatteverket.

The SINK tax is final – no annual tax return is required by the employee for income taxed under SINK.

Since January 1, 2005, employees have had the option to voluntarily opt out of SINK and be taxed under the regular Swedish Income Tax Act instead. This allows them to deduct business-related expenses and potentially reduce their tax burden.

To opt for standard taxation:

  • Submit form “Särskild inkomstskatt för utomlands bosatta” (SKV 4350).
  • In the “Other information” section (Övriga upplysningar och yrkanden), state that you want to apply Swedish income tax rules instead of SINK, and list any deductible expenses.
  • Alternatively, file a tax return the following year, requesting that income previously taxed under SINK be re-taxed under standard rules.

Long-Term Stays: More than 6 Months

An employee who stays in Sweden for more than six months may be considered a tax resident, even if officially residing elsewhere. Such individuals are subject to the same tax rules as Swedish residents.

A foreign company with a permanent establishment must:

  • Withhold income tax according to the tax tables,
  • Register as an employer,
  • Provide both Skatteverket and the employee with an annual income statement for the previous tax year.

Payments to Subcontractors

Even if work is subcontracted, withholding tax may still apply if the subcontractor does not hold an F-tax certificate.

This does not apply if the subcontractor is not established in Sweden.

A foreign company without a permanent establishment is not required to withhold tax.

However, if it employs someone who is a Swedish tax resident, the employee must file a preliminary income tax return with Skatteverket to determine their monthly tax instalments (SA tax).

Annual Income Statement for Employees

A foreign company is obligated to submit an annual income report (kontrolluppgift) for each employee, detailing:

  • taxable earnings,
  • pension rights,
  • and, where applicable, withheld taxes.

This applies regardless of whether the company has a permanent establishment in Sweden.

The income report must be submitted by January 31 of the year following the income year.

Depending on the employee’s country of residence and applicable social contributions, different reporting forms may be required. If the employee lives abroad, the report may also need to include the employee’s foreign tax identification number (TIN).

Value Added Tax (VAT / Moms)

The term “foreign entrepreneur” in the context of Swedish VAT refers to a business that does not have a place of business or a permanent establishment in Sweden, and, for individuals, does not reside or stay permanently in the country.

VAT Registration

VAT registration in Sweden is generally not voluntary. However, in some cases, a foreign business may apply for voluntary VAT registration, allowing it to take on the VAT liability itself. This typically applies to:

  • Sales of goods,
  • And in certain cases, services related to real estate located in Sweden.

For sales to private individuals, VAT registration is always required.

F-tax Certificate (Godkännande för F-skatt)

All businesses operating in Sweden can apply for an F-tax certificate. This certificate is especially important for clients who pay for services rendered:

  • If the person or company being paid holds an F-tax certificate, the client is not required to withhold tax or pay social security contributions on the payment.
  • For payments for goods, the certificate has no tax implications.

A foreign business that is operating or planning to operate in Sweden in the near future may also apply for an F-tax certificate.

This applies even if the business is not liable for income tax in Sweden.

However, foreign businesses must be able to demonstrate that they are:

  • Declaring and paying taxes and contributions in their home country,
  • And provide a certificate confirming they have no tax debts in their home country.

The same may apply to individuals who manage or control the foreign company – such as:

  • Direct and indirect owners,
  • Persons with significant influence over the company,
  • Especially in companies with four or fewer owners holding more than 50% of the total voting power.

When calculating the number of owners, close relatives (parents, children, spouses, siblings, etc.) are treated as a single person.

This includes stepchildren, adopted children, and registered partners. Cohabitants who have shared children or were previously married are treated the same as spouses.

If the business ceases operations in Sweden, this must be reported to Skatteverket in order to cancel the F-tax certificate. More details are available in the brochure “F-tax Certificate for Businesses” (SKV 432).

Deregistration and Changes to Company Information

If a business ceases operations in Sweden, it must deregister from the Swedish Tax Agency’s registers and, where applicable, from Bolagsverket (the Swedish Companies Registration Office).

Deregistration and updates can be submitted using:

  • The form SKV 4639 – Application for Deregistration/Change of Information, or
  • Electronically via Verksamt.se.

Failure to file a deregistration notice – while simultaneously stopping the submission of tax returns – may result in:

  • Late fees,
  • And Skatteverket issuing estimated tax assessments.

In some cases, a new preliminary income tax return may be required together with the deregistration notice.

This allows the monthly tax instalments to be reduced due to the closure of the business.

What tax obligations do foreign companies operating in Sweden have in 2026?

Foreign companies operating in Sweden in 2026 must comply with clear tax regulations. Learn when registration obligations arise, how F-tax works, VAT and employer contributions – and how Revea can help with proper compliance.

Sweden has for many years remained an attractive market for foreign entrepreneurs – both in the service sector, as well as project-based, technological and construction industries. An increasing number of companies are executing contracts here, seconding employees or collaborating with Swedish clients on a permanent basis.

In 2026, the taxation rules for foreign companies in Sweden remain largely stable, however the practice of their application is becoming increasingly systematized. The Swedish Tax Agency (Skatteverket) places great emphasis on ensuring that business activities conducted on Swedish territory are correctly classified for tax purposes – especially regarding the place of work performance, employer status and reporting obligations.

For foreign companies, this means the necessity of a conscious and thoughtful approach to their tax obligations, even before starting operations or executing a project in Sweden.

In this article, we explain what tax obligations may apply to foreign companies operating in Sweden in 2026 and what is worth paying attention to in practice.

When can a foreign company be subject to taxation in Sweden?

A foreign company is not always automatically subject to taxation in Sweden. The tax obligation arises only when certain conditions are met, particularly when the company:

  • performs work physically on Swedish territory,
  • employs workers who perform work in Sweden (also temporarily),
  • executes projects or services requiring presence in Sweden,
  • has or may be considered to have a permanent establishment (fast driftställe),
  • meets the conditions of so-called limited tax liability.

In practice, the decisive factor is the place where work is actually performed, not solely the company's registered office or the country where invoices are issued.

Registration of a foreign company in Sweden

Depending on the nature of operations, a foreign company may be required to register with Skatteverket as:

Employer (arbetsgivare) – if it pays salaries for work performed in Sweden.

F-tax taxpayer – if the activity is of a permanent nature or the company independently handles tax settlements.

F-tax is also significant for relations with Swedish clients.

VAT taxpayer (momsregistrerad) – in case of services or supply of goods subject to VAT taxation in Sweden.

It's worth emphasizing that registration itself does not always mean an obligation to pay income tax, but almost always involves reporting obligations.

Obligations of a foreign employer

If a foreign company employs workers performing work in Sweden, an obligation may arise to:

  • register as an employer,
  • withhold preliminary tax (preliminärskatt),
  • report salaries to Skatteverket.

In standard cases, when an employee does not have an individual tax decision, a preliminary tax rate of 30% is applied.

However, some situations may be subject to exceptions, for example based on:

  • double taxation agreements,
  • special arrangements (e.g., Öresund agreement),
  • work performed entirely outside Sweden.

Each case requires individual analysis.

Obligation to submit "special information"

Foreign companies that do not have a permanent establishment in Sweden but conduct activities related to the Swedish market may be required to submit annual "special information" (särskilda uppgifter).

The purpose of this obligation is to enable Skatteverket to assess whether:

  • there is an obligation to file a tax return,
  • the company should be registered as an employer,
  • a tax obligation arises in Sweden.

The deadline for submitting information is the same as the deadline for tax returns.

Permanent establishment (fast driftställe)

If a foreign company's activity in Sweden is of a permanent nature and involves physical presence – for example, through an office, technical facilities, long-term project or local personnel – a permanent establishment may arise.

In such a case, the company is treated as an entity conducting business in Sweden and is subject to Swedish taxation and accounting rules.

VAT in the operations of foreign companies

Foreign companies may be required to register for VAT in Sweden, among others, when:

  • they provide VAT-taxable services in Sweden,
  • they sell goods on Swedish territory,
  • they have a warehouse or inventory in Sweden,
  • they provide services to private individuals.

The applicable VAT rates are 25%, 12% and 6%, depending on the type of activity.

Cooperation with Swedish clients

If a foreign company performs work physically in Sweden and does not have F-tax, the Swedish client may be required to withhold 30% preliminary tax from the remuneration.

Therefore, in practice, F-tax is often a condition for starting cooperation.

Work performed outside Sweden

If all work is performed outside Swedish territory, and the company has no personnel or infrastructure here, as a general rule, no Swedish tax obligation arises, even if the client is Swedish.

Summary

For foreign companies operating in Sweden in 2026, the key factors are:

  • correct assessment of the place where work is performed,
  • proper registration with Skatteverket,
  • distinction between tax obligations and reporting-only obligations,
  • conscious management of the relationship with Swedish clients.

Tax reporting for the IT and tech sector in Sweden — key trends and legal changes for 2026

IT & tech in Sweden 2026: remote work, cross-border teams and PAYE increase compliance needs—get employment, payroll and tax reporting right.

The IT sector is one of the pillars of the Swedish economy. Technology companies, startups and development teams have long attracted global capital, and demand for highly qualified specialists continues to rise. As the industry evolves, the tax landscape changes with it — especially in areas connected to international work, remote setups and cross-border operations.

In 2026, several trends and regulatory developments are particularly important for IT businesses operating in Sweden or delivering projects for Swedish clients.

Remote work and distributed teams — new tax standards

Tech companies increasingly hire specialists working from different countries — including Poland. In practice, this means you must be able to:

  • determine where social security contributions should be paid,
  • clarify the employer’s obligations in Sweden and abroad,
  • handle cost treatment and reimbursement linked to remote work,
  • report employment correctly and on time.

In 2026, the Swedish Tax Agency (Skatteverket) continues to emphasize that the key factor is the place where the work is actually performed, unless rules on postings (secondments) or EU exceptions apply.

Obligations for foreign IT companies providing services in Sweden

Companies outside Sweden — including Polish software houses — may be required to:

  • register as an employer in Sweden,
  • pay Swedish social security contributions for employees working in Sweden,
  • handle wage tax-related reporting,
  • report to Skatteverket within the PAYE framework where applicable.

For software houses delivering projects on-site or in a hybrid model, these obligations are especially relevant.

Tech startups and ownership structures — what still applies

Many Swedish tech companies use holding structures that can:

  • support scaling and new investments,
  • enable more efficient capital gains taxation,
  • improve long-term planning of profit distributions,
  • protect intellectual property.

Sweden’s tax system continues to be favourable for holding companies in several contexts — including, for example, how share disposals may be treated.

Taxation of IT specialists — key risk areas

Salaries in the tech sector are often above market averages, making correct classification and reporting crucial. Typical focus areas include:

  • correct calculation of social security contributions,
  • cross-border employment and payroll handling,
  • EU rules for posting/secondment where relevant,
  • proper classification of B2B contractor vs. employment.

Misclassification can lead to tax arrears and liabilities — affecting both the worker and the employer.

R&D relief as a cost factor (but not the main topic)

Many tech businesses make use of Sweden’s R&D relief (Forskningsavdrag). In this article, however, it is only one part of the broader tax ecosystem, not the main focus.

For some IT companies it can be relevant — but not all technology activity automatically qualifies as R&D.

Tax trends in IT for 2026

Key observations for the year ahead:

  • greater importance of cross-border work setups,
  • more software houses supporting Swedish clients from abroad,
  • more frequent reviews of “where the work is performed” and where it should be taxed,
  • increased relevance of PAYE reporting for foreign employers,
  • clearer approaches to remote work after the pandemic years,
  • stronger focus on compliance in tech and digital services.

Summary

Sweden’s IT sector is growing fast, and its working models make tax matters more complex than in many traditional industries. Remote work, international teams, hybrid delivery and the increasing number of foreign providers mean that tax preparedness is essential.

Tech companies should continuously monitor obligations connected to employee taxation, payroll reporting, social security contributions and cross-border activity — and make sure documentation and classifications are correct.

Revea supports IT companies across Sweden

We can help you:

  • clarify tax obligations for IT employees,
  • manage teams working from different countries,
  • assess when a company must register as an employer in Sweden,
  • handle full accounting and advisory services for tech companies,
  • support Polish software houses delivering services to Swedish clients.

New Laws and Regulations 2026: The Complete Guide for Swedish Business Owners

We have entered 2026, and with the new year comes a series of changes in regulations affecting Swedish business life. From the revised 3:12 rules to stricter sustainability reporting requirements and new pay transparency directives. Here's everything you need to know to navigate the Swedish tax system correctly during the year ahead.

When the fog of New Year's celebrations has settled, it's time for Sweden's business owners to look forward. 2026 is a year characterized by both simplifications and new administrative requirements in the Swedish tax system. For many owners of closely held companies, the year's big news is the new dividend rules, but changes are also happening in sustainability and HR that require attention.

We have compiled the most important legislative changes and updates that have come into force or are waiting just around the corner.

The New 3:12 Rules – Simpler and Often More Favorable

Perhaps the most anticipated change for owners of Swedish small businesses is the new 3:12 rules that came into effect on January 1, 2026. The purpose of the reform has been to simplify the complex regulatory framework and equalize differences between different types of shareholders in the Swedish tax system.

Here are the most important changes:

  • Simpler calculation: The previous simplification rule (standard amount) has been replaced with a new basic amount based on the income base amount. This makes the Swedish system more predictable.
  • Eliminated salary withdrawal requirement: The controversial salary withdrawal requirement (that you must withdraw a certain salary to be credited with a salary basis) has essentially been removed and replaced with a standard deduction. This particularly benefits shareholders in companies with many employees but where the owner themselves does not withdraw a market-level top salary.
  • Shorter waiting period: The time limit for "waiting period companies" (shell companies) has been shortened from five to four years, making it smoother for liquidation or restructuring under Swedish tax law.

For those planning this year's dividend distribution, this means you should review your calculations together with your Swedish accounting consultant, as the room for low-taxed dividends may have increased.

Corporate Tax Remains Unchanged

Although proposals were discussed and submitted in 2025 to reduce the Swedish corporate tax from 20.6% to 20% as a growth measure, the reduction was not implemented in the final budget for 2026. The corporate tax in Sweden thus remains at 20.6% for the time being. However, other reliefs have been introduced, including reduced tax on employment income (see below).

CSRD: More Companies Now Covered by Sustainability Requirements

The EU directive for sustainability reporting, CSRD (Corporate Sustainability Reporting Directive), continues to be rolled out. From the financial year beginning in 2025 (with reporting in 2026), large Swedish companies that meet at least two of the following three criteria are now also covered:

  • More than 250 employees
  • More than SEK 550 million in net turnover
  • More than SEK 280 million in balance sheet total

This means that significantly more Swedish unlisted companies must now report their climate impact, social responsibility, and governance according to the ESRS standard. For smaller companies not yet directly covered, it is still high time to start collecting data, as larger customers and banks will increasingly demand this information as part of their own supply chains.

Labor Market: Prepare for Pay Transparency

One of the most important changes to prepare for during the spring is the Pay Transparency Directive. Although full implementation in Swedish law occurs in summer 2026, employers should act now.

The directive requires Swedish employers to be able to report pay gaps between genders and give employees insight into pay setting.

  • What does it mean? Job seekers have the right to receive information about starting salary or salary range already in the recruitment process. Employees gain the right to request information about average salary levels for equal or equivalent work.
  • Tip: Review your salary mappings and ensure you have clear, gender-neutral criteria for salary setting before the law fully comes into force.

Economy and Tax: This Applies in Sweden for Tax Year 2026

Enhanced Earned Income Tax Credit and Reduced Tax on Pensions

The Swedish government has implemented a further enhancement of the earned income tax credit. This means more money in the wallet for most wage earners in Sweden, with an average tax reduction of a few hundred kronor per month. Tax on pensions has also been reduced to increase incentives for a longer working life and strengthen the economy for elderly people.

Increased Travel Deduction

Positive news for commuters is that the travel deduction threshold is being adjusted in the Swedish tax system. For tax year 2026, the lower amount threshold for when you can start deducting travel to and from work has been raised from 11,000 kronor to 15,000 kronor. This means that only costs exceeding 15,000 kronor are deductible, which is a tightening compared to previous years.

ROT and RUT

The temporary increase in the ROT deduction ceiling that applied during the second half of 2024 is gone. From 2025 onwards, the regular levels apply in the Swedish tax system:

  • ROT: Maximum 50,000 SEK per person per year (30% of labor cost).
  • RUT: Maximum 75,000 SEK per person per year (50% of labor cost).The combined ceiling for ROT and RUT is 75,000 SEK per person per year.

Reduced Tax on Fuel

In line with the Swedish government's energy policy, the tax on gasoline and diesel was reduced at the turn of 2025/2026. Together with adjustments in the reduction obligation, this aims to keep transport costs down for both private individuals and businesses in Sweden.

Important Reminders from Previous Year

Some rules introduced in 2025 have now taken full effect or are important to be reminded of:

  • Växa Support: The rules for reduced employer contributions for the first employees (Växastödet) now cover the first two employees, making it cheaper for Swedish sole proprietors to start hiring.
  • Late Filing Fees: The Swedish Companies Registration Office (Bolagsverket) has increased fees for late submission of annual reports. It is now more expensive than ever to neglect deadlines – the first fee is 7,500 SEK.
  • Digital Submission: More and more Swedish business forms are encouraged (and will eventually be required) to submit annual reports digitally. If you haven't switched yet, 2026 is the year to do it.

Footnote: The information in this article is based on applicable Swedish legislation and budget decisions as of January 2026. We always recommend that you verify specific tax matters with a qualified Swedish advisor.

Tax and innovation — how to use Sweden’s R&D tax relief (Forskningsavdrag) in 2026

Sweden’s Forskningsavdrag cuts employer contributions for R&D staff in 2026—lowering innovation costs with proper documentation.

Sweden is consistently ranked among the world’s most innovative economies. Technology, automation and new solutions are supported not only by the market, but also through the tax system. One of the most practical tools for companies working with research and development is the R&D tax relief called Forskningsavdrag.

In 2026, it remains one of the most effective ways to reduce the real cost of innovation — for both small companies and large groups.

What is Forskningsavdrag?

Forskningsavdrag is a tax relief that allows companies to reduce employer social security contributions for employees involved in R&D work. It is not a deduction from taxable profit — instead it reduces payroll-related charges, which often means a direct financial effect.

Key points at a glance

  • Employer contributions can be reduced by up to 19.59%
  • Maximum base of 3,000,000 SEK per month
  • Applies to employees working with R&D
  • Can also include work performed outside Sweden, as long as contributions are paid in Sweden

This is one of the more attractive payroll-based R&D incentives in Europe because it can improve cash flow without relying on grants.

Who can use the relief?

Forskningsavdrag can be used by commercial businesses regardless of size. Eligibility is based on the nature of the work, not the legal form.

Typical eligible businesses include:

  • Technology and manufacturing companies
  • Startups and scale-ups
  • Service companies running development projects
  • Businesses developing new products, processes, services or digital solutions

Both permanent employees and contracted individuals may be relevant — provided the work qualifies as R&D and social contributions are paid in Sweden.

What activities qualify as R&D in Sweden?

R&D can include, for example:

  • Creating new products, technologies or services
  • Software development and testing of new functionality
  • Improving production and technical processes
  • Designing prototypes and models
  • Technical or scientific investigations
  • Developing new analytical methods or tools

If a project requires creativity, specialist competence and introduces something new or a significant improvement, it will often fall within the R&D scope.

Conditions you must meet

To apply the relief, the company typically needs to meet these requirements:

  • The employee spends at least 50% of working time in that month on R&D activities
  • The employee must not turn 66 during the tax year
  • The project must have a commercial purpose
  • The company must be able to document the R&D work performed

Activities funded by public institutions do not qualify for the relief.

What does the financial benefit look like in practice?

Employer social security contributions in Sweden are 31.42%.

With Forskningsavdrag, they may be reduced to around 11.83%, which can mean savings of hundreds of thousands of SEK per year if you have several R&D employees.

The relief is particularly valuable for companies employing highly qualified specialists — engineers, analysts, developers, designers, and other technical roles tied to innovation.

Why should companies use the R&D tax relief?

  • Reduces the cost of running innovation projects
  • Improves competitiveness
  • Supports R&D financing without needing grants
  • Encourages development and technology growth in Sweden
  • Helps both domestic and international companies scale faster

Summary

Forskningsavdrag is one of Sweden’s most important tax tools for supporting innovation. Companies investing in research and development can significantly reduce payroll-related costs, making it easier to scale projects, hire experts and bring new technologies to market.

Taxes on investments and capital in Sweden in 2026: ISK, K4, crypto, stock market and practical ways to reduce tax

How to navigate Swedish taxes on ISK, K4, crypto and capital gains in 2026 – and use legal strategies to reduce your overall tax burden.

Investing in Sweden is becoming increasingly popular – both among private individuals and entrepreneurs running businesses here. The Swedish tax system is considered one of the most transparent in Europe, while at the same time offering investors significant opportunities for optimisation. In practice, this means that the right choice of tools and investment structures can significantly reduce the tax you pay – and in some cases even eliminate it.

In this article, we explain how investments are taxed in Sweden – from ISK accounts and the K4 form to cryptocurrencies and corporate capital gains – and how to legally and effectively reduce your tax burden.

ISK – the account that changed investing in Sweden

The most popular way to invest in Sweden is through the Investeringssparkonto (ISK), an investment savings account designed for simple, long-term investing. This solution is particularly attractive for people who want to invest without complicated paperwork and annual tax reporting.

With an ISK, you do not pay tax on your actual profit – neither on capital gains from selling shares nor on dividends. Instead, a small schablon tax (standardised, notional tax) is calculated on the value of the portfolio. In practice, this is often lower than the traditional 30% capital gains tax.

Why is ISK so beneficial?

Because in most cases it allows you to invest without worrying about detailed reporting, and it protects investors from paying high tax in years when they realise unusually large gains.

This is one of the main reasons why more than 5 million people in Sweden now have an ISK account.

K4 – mandatory for investors outside ISK

Not all investments can be held in an ISK. Investors who trade via ordinary brokerage accounts, use foreign platforms (such as Degiro, eToro, Interactive Brokers) or invest in cryptocurrencies must report their transactions in the K4 form.

This is where you report:

  • sales of shares and funds
  • transactions in derivatives
  • cryptocurrencies
  • gains and losses from trading on foreign exchanges

All realised gains are taxed at 30%, and any losses can reduce the taxable base (within certain limits).

The most common challenge? Collecting transaction data. For cryptocurrencies or active day trading, the number of transactions can reach hundreds or thousands. As a result, more and more investors choose to have their K4 prepared by professional accounting firms.

Cryptocurrencies in Sweden – taxation without secrets

The Swedish Tax Agency (Skatteverket) has for years been clear on how it views cryptocurrencies: they are capital assets, not currency.

This means that every sale, swap or use of crypto to pay for goods or services is a taxable event.

The key rules are:

  • gains are taxed at 30%
  • every transaction must be reported in the K4 form
  • losses can be deducted, but not as fully as for shares
  • buying crypto is not taxed – tax arises only when you sell or exchange

There is currently no possibility to hold cryptocurrencies inside an ISK.

In practice, this means greater responsibility for the investor and a strong need for accurate and detailed documentation.

Dividends in Sweden – 30% tax, but not always

The standard tax rate on dividends in Sweden, the so-called Kupongskatt, is 30%.

This applies to both individuals and foreign entities.

The good news is that for investors outside Sweden, this withholding tax can often be reduced through double taxation treaties – for example to 15% for Polish tax residents.

Dividend payments within an ISK do not require any additional reporting and are not included in the K4 form.

Selling a company and capital gains – when can you avoid tax in Sweden?

Corporate capital gains in Sweden are generally taxed at 20.6%. This includes, for example, gains from the sale of shares or business interests.

However, the Swedish system offers an important exception – and this is one of the most efficient tax optimisation tools in the entire EU.

If the sold shares qualify as “kwalificerade andelar” (qualified shares) and the company is a Swedish tax resident, it may be possible to achieve full exemption from capital gains tax.

The condition?

The proceeds must be used for business-related purposes – in practice, they need to be reinvested.

This is why many Swedish tech companies and holding structures use this mechanism when selling subsidiaries or restructuring groups of companies.

How to legally reduce tax on investments in Sweden – key strategies

There is no single universal solution, but there are several strategies that are widely used in practice:

  1. Choosing the right investment account (ISK vs ordinary account)
  2. The simplest and most common way. ISK removes tax on capital gains and dividends and replaces it with a relatively low standardised tax on the portfolio value.
  3. Using capital losses in the K4 form
  4. Properly reporting and offsetting losses can reduce your annual tax bill by several thousand or even tens of thousands of SEK.
  5. Holding companies – selling a business tax-free
  6. For entrepreneurs, a Swedish holding structure can be one of the most powerful optimisation tools, especially in connection with the sale of companies or shares.
  7. Reducing tax on foreign dividends
  8. Thanks to tax treaties, the withholding tax charged abroad can often be reduced and partly credited in Sweden.
  9. Strategic investment planning
  10. The choice of investment products and platforms also affects how and where your returns are taxed. Being aware of the differences between ISK, ordinary accounts and corporate solutions is crucial.

Poland – Sweden: how does double taxation work?

There is a double taxation treaty between Poland and Sweden that protects investors from being taxed twice on the same income.

In principle, income is taxed in the country where it arises, and then offset mechanisms ensure that you do not pay tax twice on the same amount.

This is particularly important for:

  • Polish entrepreneurs operating in Sweden
  • investors from Poland earning returns on the Swedish stock market
  • people moving between the two countries

When should you seek help from a tax advisor?

The more complex your investments, the higher the risk of mistakes.

Professional support is especially valuable when you:

  • invest through several platforms at the same time
  • trade or hold cryptocurrencies
  • own a company or a holding structure
  • plan to sell shares in a business
  • want to minimise your tax burden within the boundaries of the law

Having an expert prepare your K4 or advise on the structure of your investments can often save tens of thousands of SEK – and in corporate transactions, sometimes much more.

Need help with reporting investments, K4 or tax planning?

At Revea, we support investors, entrepreneurs and private individuals with:

  • tax returns and reporting
  • optimisation of investment structures
  • holding and group structures
  • taxation of cryptocurrencies
  • cross-border tax advice between Poland and Sweden

Property Tax in Sweden – How Property Value and Tax Are Calculated

Learn how property tax is calculated in Sweden and what rates apply for 2025.

In Sweden, property owners pay an annual tax based on the type, value and location of the property.

For 2025, the rates are set centrally by Skatteverket, but they vary depending on the type of property.

How Property Value Is Calculated

The property tax is based on the tax assessment value (taxeringsvärde), which is updated every few years by Skatteverket.

This value generally corresponds to around 75% of the property’s market value.

The following factors are considered:

  • the size of the building and plot,
  • the location,
  • the year of construction and technical standard.

Property Tax Rates in 2025

Single-family houses (småhus)

  • Tax rate: 0.75% of the assessed value.
  • Maximum tax amount: SEK 9,287 per year (2025 limit).

Cooperative apartments (bostadsrätt)

  • Individual apartment owners do not pay property tax directly.
  • The housing association pays property tax on the collectively owned property.

Commercial buildings

  • Tax rate: 1%–1.3% of the assessed value.

Vacant land

  • Tax rate: 1% of the land value.

Newly Built Properties

New houses and residential buildings are exempt from property tax for the first 15 years after construction.

The exemption is applied automatically once the property is registered with Skatteverket.

Deadlines and Payment

Property tax is collected by Skatteverket as part of the annual tax settlement.

Information about the amount due appears in the taxpayer’s account on Mina sidor.

The tax can be paid in one instalment or in four instalments throughout the year.

Selling Property – Capital Gains Tax

When selling property in Sweden, a capital gains tax of 22% applies to the profit from the sale.

The gain is calculated as the difference between the selling price and the purchase cost, including improvement and renovation expenses.

Property Tax in Sweden – Key Takeaways

Sweden’s property tax system is relatively straightforward but requires an understanding of how assessment values and tax rates differ for each type of property.

Knowing these principles helps property owners avoid errors and plan their finances more effectively.

Revea assists property owners in analysing costs, reporting property-related taxes and preparing the necessary documentation for annual declarations.

Taxes in Sweden for Freelancers and the Self-Employed

Learn how freelancers in Sweden pay taxes and what deductions and rules apply in 2025.

Sweden is a business-friendly country for self-employed professionals, but running your own business comes with certain tax and administrative responsibilities.

To avoid mistakes and unnecessary costs, it’s important to understand the main tax rules for freelancers in 2025.

Registering a Business in Sweden

Anyone working on a self-employed basis must register their business with Skatteverket (the Swedish Tax Agency) and obtain:

  • an F-skatt number (entrepreneur’s tax ID),
  • a VAT number, if providing goods or services subject to VAT.

Registration allows freelancers to pay their own taxes and social contributions, and to issue invoices to clients.

Preliminary Tax and Annual Returns

Freelancers pay income tax in the form of monthly advance payments (preliminärskatt).

The amount depends on the expected annual income reported to Skatteverket.

At the end of the tax year, you must submit an annual tax return (Inkomstdeklaration 1 or NE attachment) to reconcile the final tax amount.

Contributions and Business Expenses

Self-employed individuals in Sweden are required to pay:

  • income tax – around 30–33%, depending on the municipality,
  • social security contributions (egenavgifter) – approximately 28.97% of income,
  • VAT (moms) – 25%, 12%, or 6%, depending on the industry.

Operating expenses such as equipment, software, travel, or marketing costs can be deducted from taxable income.

Tax Deductions for Freelancers

Freelancers are entitled to the same deductions as other taxpayers, including:

  • reseavdrag – travel deductions for client visits,
  • deductions for office, equipment and internet costs,
  • depreciation of assets worth more than SEK 25,000,
  • accounting and business software expenses.

Deadlines and Tax Responsibilities

The deadline for filing the 2024 tax return is 2 May 2025, and for 2025 – early May 2026.

All declarations and payments are handled online through Skatteverket’s Mina sidor portal.

Late payments may result in interest and additional fees, so keeping track of deadlines and balances is essential.

Freelancing in Sweden – Key Takeaways

Working as a freelancer in Sweden offers flexibility and independence – but also demands good organisation and awareness of tax obligations.

Understanding tax rules, rates and deductions helps you optimise your income and avoid costly errors.

Revea supports freelancers and self-employed professionals with accounting, reporting and tax planning, ensuring your business runs smoothly and in compliance with Swedish law.

Investment Tax in Sweden – How to Calculate Capital Gains Tax

Learn how capital gains are taxed in Sweden and what the 2025 rates mean for investors.

Investing in Sweden can be highly profitable, but it requires an understanding of how capital gains are taxed.

The Swedish tax system distinguishes several types of capital income, including profits from the sale of shares, investment funds and property, as well as bank interest and dividends.

What Does Capital Gain Mean in Practice?

A capital gain (kapitalvinst) arises when the sale price of an asset exceeds its purchase price.

This applies to:

  • shares and company holdings,
  • units in investment funds,
  • property or shares in property,
  • other financial investments.

Capital gains tax in Sweden applies to both private individuals and businesses.

Capital Gains Tax Rates in 2025

Sweden applies a flat 30% tax rate on most types of capital income, including:

  • profits from the sale of shares and funds,
  • bank interest,
  • dividends.

If you make a loss, it can be partly deducted:

  • 70% of the loss can be offset as an expense,
  • losses on shares or funds can only be deducted against the same type of asset.

Tax on Property Sales

The sale of property in Sweden also generates capital income.

The tax is calculated as 22% of the gain (which corresponds to 30% of two-thirds of the profit under Swedish tax rules).

Deductible expenses include:

  • purchase costs of the property,
  • renovations and improvements that increase its value,
  • notary fees and brokerage commissions.

Tax on Foreign Investments

Individuals who live in Sweden and have tax residency status must declare all foreign investments and pay capital income tax on their worldwide income.

To avoid double taxation, Sweden has signed tax treaties with many countries – including Poland.

Declaration and Payment of Tax

Capital gains tax is reported in the annual income tax return submitted to Skatteverket.

For the sale of shares, funds or property, all relevant information can be entered through Mina sidor (My Pages).

Skatteverket automatically calculates the amount of tax payable based on the data provided.

Investment Tax in Sweden – Key Takeaways

Understanding how investments are taxed in Sweden helps you avoid mistakes and unnecessary costs.

With proper planning, you can optimise your tax situation and even obtain a partial refund.

If you invest in Sweden or abroad, Revea can assist you in analysing capital gains, accounting for losses and preparing a compliant tax declaration.
