F-tax registration help for foreign entrepreneurs

Swedish clients prefer to engage companies that have Swedish F-tax. For this reason, foreign companies that run businesses in Sweden should apply for approval for F-tax. This also applies to companies that do not pay income tax in Sweden.

Companies that have F-tax are responsible for paying their own preliminary tax and other charges. If the company does not have F-tax, the client may be responsible for paying preliminary tax and employer’s social security contributions for work performed.

The Swedish Tax Agency checks with the home state’s tax authority to ensure that the contractor is not remitted for unpaid taxes and fees there. If all the other conditions are otherwise met, then an approval for Swedish F-tax is then decided. The processing times of Swedish Tax Agency can vary between 6 – 10 weeks and sometimes longer.

If you are in need of F-tax, start the process now!

If you hire a foreign company that performs services in Sweden or has employees in Sweden, new rules apply from January 2021.

If the foreign company is not registered for F-tax in Sweden, you must make a tax deduction of 30% on the invoice amount. Read more here what applies.

From 1 January 2021, there are new rules for foreign companies that have employees in Sweden or receive compensation for work in Sweden. The rules mean that Swedish payers are obliged to include tax (30%) for all compensation for work performed in Sweden if the recipient is not registered for F-tax in Sweden. Full payment for invoices where there is no information about F-tax registration will thus not be possible.


What happens if information about F-tax registration is not stated on the invoice?

As stated above, the person who pays the invoice is obliged to contain the corresponding 30% of the part of the invoice amount that pertains to work performed in Sweden in cases where the supplier is not F-tax registered in Sweden. Payment for the entire invoice amount will therefore not be possible. To avoid this, the foreign supplier must register for F-tax.

The company that has hired the foreign supplier must then report the deducted tax via AGI (To the Tax Authorities) This also means that you must be registered as an employer in Sweden.


F-tax certification As a rule, sole traders are granted an F-tax certificate. This means that they are responsible for paying tax and self-employed contributions (“egenavgifter”) on the income they receive from any work they carry out.

F-TAX and ID06

Connection to the ID06 System is conditional upon that the User Company:
(a) complies with the ID06 System’s objectives;
(b) complies with applicable law in all essential respects; and
(c) is approved for F-tax by the Swedish Tax Agency. The government, municipalities and county councils are exempt from this condition.

To be connected to ID06 system the company need to have Swedish F-tax number, that is in the agreement, GENERAL PROVISIONS FOR CONNECTION OF USER COMPANIES TO THE ID06 SYSTEM. For companies that does not have F-tax number they can register and have 90 days to update that information into the ID06-system.

New Swedish law change 2021

The Government has announced a new so-called economic employer concept in Sweden. The new regulation will have the impact that more  employed people by foreign employers will become taxable in Sweden.

The new regulation contains a part that means that foreign companies, which do not have a permanent establishment in Sweden, will make tax deductions on wages for work performed in Sweden, from day one.

Be prepared – we help you with the application!
