How often do you file VAT in Finland?

Filing frequency depends on your annual turnover:

• Under €30,000: you file once a year
• €30,000 to €100,000: you file quarterly
• Over €100,000: you file monthly

Most gig workers and small toiminimi operators sit in the first bracket and file annually.

The turnover figure that matters is your total business turnover excluding VAT, across all your activity. If you work through more than one platform, they are added together. You cannot split them to land in a friendlier bracket.

For annual filers, the return covers the calendar year and is due by the last day of February of the following year.

For monthly and quarterly filers, the return is due on the 12th day of the second month following the end of the period. So a January return is due 12 March; a first-quarter return is due 12 May.

The payment is due on the same date as the return. Filing on time and paying late still costs you interest, so treat them as one deadline rather than two.

If the due date falls on a weekend or public holiday, it moves to the next business day.

Filing once a year sounds like the obvious win, and administratively it is. The risk is cash flow.

A full year of VAT falls due in one payment at the end of February. For a courier turning over €2,000 a month, that is a four-figure bill arriving in one go, on money that was received and spent across the previous twelve months.

The only reliable way to handle this is to move the VAT portion out of your spending account as it arrives, every month, and not touch it. Roughly 20% of each VAT-inclusive payout is a reasonable working estimate before deductions.

If you are in the VAT register, you file for every period, including periods where you sold nothing.

A period with no activity gets a return with zeros in it. Not filing it is a missed filing and attracts the late-filing penalty exactly as if you had earned money and stayed quiet.

This catches people who stop couriering for a while without deregistering. The registration keeps generating obligations until you close it.

Your frequency is set from the turnover estimate you give when you register, and reviewed against your actual figures.

If your turnover grows past a bracket boundary, the frequency changes. It is not automatic in the sense of happening without you: you notify Vero, or Vero notifies you following an assessment, and the new frequency applies from a stated date.

The practical failure mode is a courier who registered at low turnover, started working full time, crossed €30,000, and carried on assuming annual filing. Quarterly deadlines had been passing unnoticed for a year, each one accruing its own penalty.

If your income has changed materially, check which bracket you are actually in rather than the one you registered under.

A surprising share of filing problems are not late returns but correct returns filed into the wrong period.

The rule is that a sale belongs to the period in which it was made, not the period in which the money reached your account. With platform work these are often different: deliveries completed in late March may be paid in April.

For couriers on self-billing, the practical anchor is the settlement documentation the platform issues, which states the period it covers. Use that period, not your bank statement date.

Two consequences worth remembering:

• Your VAT return for a period will not exactly match the deposits that landed in that period, and it is not supposed to.
• Fixing a wrong-period filing means two replacement returns, one to remove the figures from the period they should not be in, and one to add them where they belong.

Getting this right the first time is considerably less work than correcting it.

You can apply to file more often than your turnover requires. Some businesses in a regular refund position choose monthly filing so that refunds come back sooner rather than sitting with Vero for a year.

Moving to a longer period than your turnover allows is not available. The brackets set a maximum interval, not a preference.

Voluntary changes generally apply for a minimum period rather than being switchable month to month, so it is a decision to make deliberately.
