Latvia Postpones B2B e-Invoicing Mandate to 2028

Latvia is gearing up for the mandatory adoption of electronic invoicing. The Ministry of Finance has drafted a bill, "Amendments to the Accounting Law" (24-TA-438), which mandates the use of electronic invoices. The mandate will apply to the public sector and businesses registered in Latvia for VAT purposes.

The Latvian government has officially announced a postponement of its mandatory electronic invoicing requirements for business-to-business (B2B) transactions.

Initially slated for rollout on January 1, 2026, the mandatory B2B e-invoicing requirement has now been deferred to January 1, 2028. However, companies will be encouraged to begin voluntary adoption starting January 1, 2026.

e-Invoicing Timeline

• January 1, 2026: Electronic invoicing will be mandatory for transactions between the state administration and businesses, including G2G (Government to Government), B2G (Business to Government), and G2B (Government to Business).
• January 1, 2028: The mandate will be expanded to cover B2B (Business to Business) transactions.

The submission of electronic invoice data to the State Revenue Service (SRS) will become mandatory. The SRS will collect this data through a centralized portal from both public sector suppliers and taxpayers.

Electronic invoices must be in XML format and comply with the Peppol BIS Billing 3.0 standard.

Under the national e-Invoicing framework, invoices may be submitted through three options:

• The free national delivery platform;
• Via certified Peppol service providers;
• Or directly between trading partners, provided both parties agree on the method.

Regardless of the delivery channel used, all invoices must be transmitted to the Latvian tax authority to ensure compliance and reporting integrity.
