Estonia e-Invoicing Mandate 2027
Post-audit · buyer's-choice e-invoicing · EN 16931 over Peppol and accredited operator networks
E-invoicing is mandatory in Estonia for B2G transactions and, since 1 July 2025, for any B2B supply where the buyer is registered as an e-invoice recipient in the Commercial Register and asks for one. There is no general B2B mandate and no clearance or real-time reporting. The Ministry of Finance has proposed extending e-invoicing to all VAT-registered B2B transactions from 2027, but the legislation is not yet adopted.

Estonia e-invoicing guide on e-Invoice.appEstonia e-invoicing: frequently asked questions
How does Estonia's buyer's-choice rule work in practice?
An accounting entity flags itself as an e-invoice recipient in the Commercial Register. That entry is public, so suppliers can check it before invoicing. Once a registered buyer requests e-invoices, the supplier must issue them in a structured format rather than PDF or paper. The obligation is triggered by the buyer's registration and request, not by turnover or sector, which is why Estonia sits between a voluntary and a mandatory regime.
How does a business register as an e-invoice recipient, and how are e-invoices actually sent?
Registration is made through the Estonian Commercial Register maintained by the Centre of Registers and Information Systems (RIK). Delivery runs over the Peppol network or through accredited domestic e-invoice operators that have roaming agreements with one another, and smaller businesses can use RIK's free e-Arveldaja tool to issue and receive e-invoices without buying a separate platform.
How long must Estonian e-invoices be archived, and does the original format have to be preserved?
Accounting source documents, including e-invoices, must be retained for seven years from the end of the financial year under the Accounting Act, and no qualified digital signature is required for VAT validity. The rules on preserving the original structured format, acceptable conversion, and hosting archives outside Estonia are covered in the detailed Estonia guide on e-Invoice.app.
