Tax return – the self-employed
You must complete and submit the Business tax return (Form 5) for every year – including any year when you have not had any activity.
When must the business tax return be submitted?
The deadline for this return is 2 April 2020.
If you send it after the date when it is due, you will have to pay a late-filing penalty fee.
If you do not submit your return at all or if you submit an incomplete return, you may have to pay a punitive tax increase.
You may ask for an extension of time for filing the tax return if you have a valid reason for it, for example if you get ill. Complete an application form and send it before the deadline date of the return. Log in to MyTax to complete the application for extension of time, or print it out on paper, fill it out, and send it to the Tax Administration.
Remember to submit your personal tax return as well
You should also check your personal pre-completed tax return and add any missing information or make corrections if necessary. The due date for the personal return is 2 April 2020 as well.
Besides MyTax, you can send your business tax return:
- The Ilmoitin.fi website – upload a file generated by your accounting software
- Tyvi services (some of the services are subject to a charge).
You also have the option to file your return on paper. The paper forms must arrive at the Tax Administration on the deadline date at the latest.
If you have filed your tax return on paper or through some other electronic service than MyTax, the details you have given will be displayed in MyTax later. If you can see a notice of a missing tax return in MyTax, but you have sent the return on paper or through another e-service, you can disregard the notice. When your tax return has arrived, MyTax will no longer show the notice.
Self-employed individuals must file an income tax return in Finland to report the important facts about their business if the business has a registration in Finland and a Finnish Business ID.
Business tax returns (Form 5) must be filed by 2 April 2020, or by 19 May 2020 for non-resident taxpayers. The deadline that applies to you is shown in MyTax or on the tax return form you received.
Any corrections to your personal pre-completed tax return should also be made no later than on the same day.
File the tax return for every year
Foreign self-employed individuals conducting a business or pursuing a profession are not always required to pay Finnish taxes although they might be active in Finland. Tax treaties often prevent Finland from taxing their business income. For example, no tax is levied when the individual is not treated as having a permanent establishment in Finland.
Even if no Finnish tax seems likely, the self-employed individual must fill in and file a tax return for his or her business activities and enclose a free-text letter in order to give the reasons why they should pay no Finnish income tax.
