Invoice requirements in Finland

Finnish VAT invoices must show the seller's and buyer's details, the VAT number, the rate and amount of VAT, and the sale details. Businesses below the EUR 20,000 threshold do not have to register, but they must not charge VAT. The Finnish Tax Administration's invoicing guidance used here is an archived version, so confirm current thresholds before use.

ALV (VAT) standard rate25.5%

Standard 25.5% since 1 September 2024. Reduced 13.5% covers groceries, restaurant and catering, books, pharmaceuticals, sanitary products, passenger transport and accommodation; it was cut from 14% on 1 January 2026. Reduced 10% now covers only newspapers and magazines. A 0% rate applies to certain exports and intra-EU supplies.

Registration

A business does not have to register for VAT while its turnover stays at EUR 20,000 or less in a calendar year (raised from EUR 15,000 on 1 January 2025); registration is required from the day the limit is exceeded.

E-invoicingE-invoice on request

There is no general B2B e-invoicing mandate. Under the Act on Electronic Invoicing (241/2019), public bodies and businesses can demand e-invoices from suppliers since 1 April 2020, and VAT rules allow e-invoices only where the buyer has accepted them.

Late payment

Under the Interest Act (korkolaki 633/1982), late interest is the Bank of Finland reference rate plus 7 points for general claims (section 4) and plus 8 points for commercial contracts (section 4a). The reference rate is 2.5% for 1 July to 31 December 2026, so commercial late interest is 10.5% for that half-year. A fixed EUR 40 compensation applies to late commercial payments.

What the invoice must show

Compare your draft with this checklist. What applies depends on the parties, the transaction, your tax status and the document type.

  1. Issue date and a unique sequential invoice number.
  2. Seller's and buyer's names and addresses, with the seller's Finnish VAT identification number. The buyer's VAT number is also required where reverse charge or an intra-EU supply applies.
  3. Quantity and nature of the goods, or extent and nature of the services, and the supply date (or prepayment date) if it differs from the issue date.
  4. VAT base for each rate or exemption, unit price excluding VAT, any discount not already in the unit price, the VAT rate applied and the VAT amount payable.
  5. Reference to the exemption or reverse charge where it applies, and for corrections a reference to the original invoice and what changed.

Tax notes

For reverse charge the invoice must carry the words 'Reverse Charge' and the buyer's VAT number, and must not show a VAT rate or VAT amount. A plain statement of exemption, such as 'VAT-exempt supply', is enough.

Intra-EU goods invoices must be issued by the 15th day of the month after the supply, and services under the general rule by the 15th day of the month after the month in which they were supplied.

Simplified invoices are allowed for smaller sales up to EUR 400 including VAT according to the archived Vero guidance; confirm this limit on the current Vero page before relying on it.

Electronic invoicing

Finland has no general B2B e-invoicing mandate. Under the Act on Electronic Invoicing (241/2019), public bodies and businesses can demand e-invoices from suppliers since 1 April 2020, and VAT rules allow an e-invoice only where the buyer has accepted electronic invoicing.

Late payment

Under the Interest Act (korkolaki 633/1982), late interest is the Bank of Finland reference rate plus 7 points for general claims (section 4) and plus 8 points for commercial contracts (section 4a). The reference rate is 2.5% for 1 July to 31 December 2026, so commercial late interest is 10.5% for that half-year. A fixed EUR 40 compensation applies to late commercial payments.

Record keeping

Keep VAT invoices for at least six years from the end of the year after the tax period. The Accounting Act can require longer for accounting records.

Watch out for

  • The Vero invoice requirements page used here is an archived version (valid 2019 to 2023); check the current invoice rules, simplified-invoice limit and retention period on vero.fi before relying on them.
  • The standard rate has been 25.5% since 1 September 2024 and the reduced rate is 13.5% since 1 January 2026, so invoices must use the rate in force on the supply date.
