Filing self-assessed taxes online
Individuals
Household employers, operators of agriculture and forestry, and operators of a trade or business can file VAT, employer's contributions and other self-assessed taxes in MyTax.
Alternatively, if their accounting system creates an electronic version of this tax return, operators of agriculture and forestry and operators of a trade or business can submit it via Ilmoitin.fi.
Wages paid on 1 January 2019 or later must be reported to the Incomes Register.
