If you are going to stay longer than a year, you can get the right to be registered in a Finnish municipality of domicile. The Finnish Digital Agency will look into your case from the perspective of the legal requirements in order to ascertain whether a Finnish municipality should be included in the data records as your municipality of domicile.

More information about taxation and getting a tax card

Employers can request their workers’ tax numbers

Submit information in Ilmoitin.fi

Send a file containing your workers’ personal IDs to the Tax Administration in the Ilmoitin.fi e-service.

Ask that the workers are added to the public register of tax numbers in the construction industry.

The tax numbers are entered in the public register automatically if you request tax numbers for at least 20 workers.

You can also send us a tax number request if you already have your workers’ tax numbers but you want them entered in the tax number register.

Submit the information as a file in Ilmoitin.fi following the data format specification: employer’s tax number requests.

Register tax numbers in MyTax

As an employer, you can also register tax numbers in MyTax with your worker’s tax number or their personal ID. You will receive a notification of registration after you have submitted the registration request. 

If the workers have been registered with their personal IDs, you will get back the registered individuals’ tax numbers.

Other methods

You can also register a tax number by calling our service number +358 29 497 070 (standard call rates) or by visiting a Tax Administration office.

If your construction site will have foreign individuals who need a Finnish personal ID and a tax number, they must visit a tax office in person. If there are more than 5 of them, you must make an appointment.

 

Students and teachers also need a tax number if they visit a construction site. The tax number can be shown on the student/teacher ID provided by the educational institution, in which case the student/teacher card can also work as an ID badge.

Educational institutions can request the registration of students

The educational institution can

  • make a list of students who need a tax number
  • ask for them to be entered into the public register of tax numbers

The list must include the name, personal ID and signature of each student.

The document must also specify the member of staff at the educational institution who has been authorised to apply for the issuing and registration of tax numbers on students’ behalf. This enables the Tax Administration to send confirmation of the tax numbers to the right person.
