Finland accounting compliance requirements

Finnish bookkeeping follows the kirjanpitolaki (Accounting Act), and public sector invoicing has been mandatory in the Finvoice-compatible EN 16931 standard since 1 April 2019 under the Act on Electronic Invoicing (241/2019), though there is no B2B e-invoicing mandate. Businesses with annual turnover above EUR 10,000 can request e-invoices from suppliers, and Verohallinto is developing a real-time economy initiative that could eventually let VAT returns be pre-filled from e-invoice data.
