Self-assessed tax return (4001e)
The self-assessed tax return (formerly the Periodic tax return) must be electronically filed.
To file VAT returns, employer's contributions and other self-assessed taxes on paper is not allowed unless there is a special reason (if electronic filing is impossible due to technical reasons etc.).
If you opt for paper filing, send the completed form to:
Finnish Tax Administration
Oma-aloitteisten verojen optinen lukupalvelu / OCR service for self-assessed taxes
P.O. Box 5000
(Transfer tax form (6012e) should not be sent to this address.)
Use the 2018 self-assessed tax return also for filing and correcting the information for earlier years.
