4. Date not setB2BProposedsend and receive

   Ministry of Finance considering a VAT Act amendment for mandatory e-invoicing of all VAT-subject B2B transactions and abolition of the EUR 1,000 reporting threshold (expected to be implemented by 2027 per the EC factsheet)

Details and caveats

The B2B obligation applies only when the buyer is registered as an e-invoice recipient (buyer's choice), so it is narrower than a general mandate. Decentralised model: entities receive via private service providers (e.g. Billberry, E-arveldaja, Finbite, Telema, Unifiedpost); RIK offers a free tool. No real-time reporting; VAT return annex KMD INF covers transactions above EUR 1,000. EC factsheet last updated Aug 2025. Archiving: copies of issued invoices and received invoices must be kept for 7 years from issue or receipt, electronic invoices in electronic form (Estonian Tax and Customs Board, VAT Act s. 37).
