What is Swedish F-tax (F-skatt), and Why Do You Need it?
Updated: Oct 13
Foreign companies that perform services in Sweden are often required to obtain Swedish F-tax approval. Without Swedish F-tax or a Withholding Exemption Decision, a Swedish customer must normally withhold 30% tax from payments.
This article explains how Swedish F-tax works for foreign companies, when it is required, and which risks and reporting obligations may follow.

What is Swedish F-tax?
Sweden’s F-tax (F-skatt) system forms a central part of the Swedish tax framework. A company that is approved for F-tax is responsible for paying its own taxes to the Swedish Tax Agency.
The practical effect is that no tax withholding needs to be made on payments to a company that holds F-tax. The Swedish customer pays the invoice in full, and the company handles its own tax obligations.
Do foreign companies need Swedish F-tax?
How the rules changed
Period | Who needed F-tax to avoid withholding on payments for services? |
Before 1 January 2021 | Swedish companies and foreign companies with a permanent establishment in Sweden |
From 1 January 2021 | All foreign companies performing services in Sweden, unless they hold a Withholding Exemption Decision instead |
The current rules
Since 1 January 2021, the main rule is that all foreign companies performing services in Sweden must hold either:
Swedish F-tax approval, or
If neither is in place, the Swedish customer must withhold 30% of the payment for services performed in Sweden. The foreign company then receives only 70% of the invoiced amount, while the withheld portion is reported and transferred to the Swedish Tax Agency.
If the customer fails to withhold when required, it may become liable for the tax and face penalties. Many Swedish companies therefore refuse to pay foreign contractors unless they can present F-tax approval or a Withholding Exemption Decision.
What happens if a foreign company has no F-tax?
Assume a Polish construction company travels to Sweden to perform services for a Swedish customer. The company holds neither F-tax nor a Withholding Exemption Decision.
The invoice
The Polish company invoices EUR 100,000 for the project in Sweden.
30% is withheld
The Swedish customer must withhold EUR 30,000 and pay it to the Swedish Tax Agency. The Polish company receives only EUR 70,000.
A slow refund
The company can later request a refund from the Swedish Tax Agency, but the process is often slow and administratively burdensome.
It is generally advisable to obtain F-tax approval or a Withholding Exemption Decision before starting work in Sweden.
What are the effects of being approved for F-tax?
The primary effect is that invoices are paid in full for services performed in Sweden, with no 30% withholding by the Swedish customer. This is very positive from a cash flow perspective. There are also compliance consequences.

What is Specific Information
A non-Swedish company approved for Swedish F-tax is normally required to file so-called Specific Information (Swedish: särskilda uppgifter) each year from the date of approval.
Specific Information is a lightweight corporate filing. Its purpose is to give the Swedish Tax Agency information about the company’s activities in Sweden. The information is used to determine whether the foreign company may be liable to Swedish corporate income tax through a permanent establishment.
F-tax and the ID06 requirement
For many non-Swedish companies, the need for Swedish F-tax is closely connected to ID06. ID06 is the identification and electronic passage system used on Swedish construction sites, and it is often required for workers to gain access.
In practice, foreign construction companies frequently need F-tax before they can obtain ID06 cards for their workers. Without ID06, workers may not be allowed to enter the site.
F-tax versus a Withholding Exemption Decision
In many cases, a Withholding Exemption Decision is the more practical solution, particularly for foreign companies carrying out short-term projects in Sweden.
F-tax | Withholding Exemption Decision | |
Effect on payments | No withholding by the customer | No withholding by the customer |
Processing time | Usually 2-4 weeks | Can be a little faster |
Compliance burden | Higher | Lower |
Annual Specific Information filing | Yes | No |
Corporate tax returns | Depends on the company’s situation | Depends on the company’s situation |
Works for ID06 | Yes | No |
Best for | Longer projects and companies that need ID06 | Short-term projects without ID06 needs |
Based on practical experience, an exemption decision is often cheaper, faster and less risky than full F-tax, especially for companies without a permanent establishment in Sweden.
If your company needs ID06 cards for its employees, you will need F-tax.
Risks when applying for Swedish F-tax
In practice, the F-tax application itself can be a risk for non-Swedish companies. We have seen several cases where information provided in the application was later used by the Swedish Tax Agency to support an assessment that the foreign company has a permanent establishment in Sweden, and therefore a Swedish corporate income tax liability.
The F-tax and permanent establishment systems are closely connected, and an incorrectly structured application can create unnecessary tax exposure. The application should therefore be prepared carefully, with a clear understanding of the permanent establishment rules. Foreign companies should consider engaging an adviser who understands both systems before submitting it.

Frequently asked questions about Swedish F-tax
Do all foreign companies need Swedish F-tax?
Not always. In some cases, a Withholding Exemption Decision is enough to avoid withholding on payments from Swedish customers.
How long does F-tax approval take?
Processing times at the Swedish Tax Agency are typically between two and four weeks, although this can vary depending on the complexity of the case.
Can a company recover withheld tax?
Yes. A foreign company can request a refund from the Swedish Tax Agency. The process can be slow and may require additional filings and documentation.
Does F-tax mean the company has to pay Swedish corporate tax?
Not necessarily. F-tax approval mainly affects withholding on payments. Actual Swedish corporate tax liability depends on whether the company has a permanent establishment in Sweden.
Do we need F-tax to get ID06 cards?
In practice, yes. A Withholding Exemption Decision is not enough for ID06, so companies that need ID06 should apply for F-tax.
