About Estonia E-Invoicing

Estonia, a digital-government pioneer, mandates B2G e-invoicing since 1 July 2019 under EN 16931. Amendments to the Accounting Act (passed 18 September 2024) introduced a unique 'buyer-choice' B2B regime from 1 July 2025: any business registered as an e-invoice recipient in the Commercial Register has the legal right to demand structured e-invoices from its suppliers. The Ministry of Finance has signalled its intent to introduce a blanket mandatory B2B e-invoicing requirement in 2027, alongside removal of the €1,000 reporting threshold. Estonia follows a decentralised model with no central national platform; invoices flow through certified service providers (e.g. Telema, Finbite, Unifiedpost) interconnected via roaming agreements and Peppol.
