When can I use a paper form?

You can file on paper only if there is a special reason (for example, if electronic filing is impossible due to technical difficulties). If you file on paper, you need not apply for a special permission, and the Tax Administration does not need to be notified of the reason in advance.. The Tax Administration may ask for the reason in connection with tax control.

Send the paper form to:

Finnish Tax Administration
OCR Service of corporate taxpayers’ returns - Yhteisölomakkeiden optinen lukupalvelu
P.O. Box 200
FI-00052 VERO

Please notice when filling out the tax return

  • If you opt for sending the tax return by post, we recommend that you fill out the form on your computer before printing it out. It is important that you fill in the details clearly, because they are read by machine.
  • If you file the tax return on paper, the details on financial statements which are transmitted to the Trade Register must be stapled together with Form 63 (Financial Statements for the Tax Administration and the Trade Register office) as the cover page.
  • Whenever a corporate taxpayer has assets to report – even during the accounting periods when you booked no depreciation expenses or made no reserves – Form 62 is a mandatory enclosure (Itemization of reserves, revaluations and depreciation). Complete any other enclosure forms if necessary.
