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.
