Non-listed companies must submit an annual information return if they have issued corporate stocks to company employees for subscription (§ 66a of the act on income tax (Tuloverolaki 1535/1992).
The companies must submit the information for any issues of corporate stock to employees, also providing data on the subscribed shares. Always submit an annual information return for any calendar year when an employee has subscribed shares.
How to submit the annual information return
You can file the annual information return in MyTax. After logging in to MyTax, select Report or request information in a limited scope.
You can also send the annual information return via Ilmoitin.fi. You need a separate file that matches the record description of the annual information return.
