Finnish VAT invoice particulars, general six-year retention and named exceptions, and the electronic availability/on-request boundary are reviewed from current Tax Administration guidance. This generator does not route public-sector e-invoices or make authority submissions. Business/VAT ID validation and transaction-specific exemption, reverse-charge, margin-scheme and cross-border treatment remain separate checks.
