- Latvia has formalized e-invoicing channels and mandatory reporting procedures to the State Revenue Service (SRS) starting in 2026.
- Three e-invoice exchange methods are allowed: Official E-Address, Service Providers, and other channels like EDI or email (with specific requirements).
- Reporting to the SRS is required for all e-invoices, with the process varying by delivery channel; deadlines are immediate but no later than five working days after issuance.
- E-invoices must use structured XML format compliant with UBL 2.1 and Peppol BIS Billing 3.0.
- From January 1, 2026, e-invoicing is mandatory for B2G, G2G, and G2B; from January 1, 2028, it becomes mandatory for all domestic B2B transactions.
