Online service for car tax
Car tax payments are transferred to the Tax Administration’s bank account after 1 to 3 days even if this e-service is temporarily offline
If you send your payment in this e-service and an error message appears, your payment will still be transferred to the Tax Administration after 1 to 3 days. The Finnish Traffic and Communications Agency (Traficom) will receive permission for vehicle registration when the payment has arrived in the Tax Administration’s account.
If there is an error in the e-service, make sure that the payment has not been debited from your bank account before you make the online payment again. If you accidentally pay too much, you will receive your excess payment back in a week.

Self-employed individuals (“toiminimi”):
- If you log in with your online banking codes, enter your personal details in the return, not your company’s details.
