Self-assessed tax return (4001e)
You can file and pay self-assessed taxes (such as value-added tax or lottery tax) in MyTax.
Tax returns on self-assessed taxes must be filed electronically. Filing on paper is allowed only in exceptional cases.
You can submit the information electronically, for example:
- via an API
- by uploading a file to the Ilmoitin.fi e-service.
Note: Although excise duties have been self-assessed taxes since 1 January 2021, they are not filed on Form 4001e. Read the instructions for filing and paying excise duty
