🇨🇿 E-Invoicing in Czech Republic

B2G MandatoryPeppol

Verified: 23 February 2026

Czech Republic has a B2G-only e-invoicing mandate with no plans for mandatory B2B. Public authorities must accept e-invoices via the NEN platform. The country focuses on the monthly VAT Control Statement (Kontrolni hlaseni) for transaction reporting. B2B e-invoicing is voluntary and requires buyer consent.

TL;DR

Czech Republic requires (B2G) e-invoicing using isdoc__version_5_2__, ubl_2_1, edifact, peppol_bis_3_0 formats. Connected to the Peppol network for cross-border exchange.

Implementation Notes

NEN platform. B2G suppliers can optionally submit through NEN, which accepts ISDOC (Czech national format), UBL 2.1, EDIFACT, and Peppol BIS 3.0. Suppliers are not required to issue e-invoices — the obligation is only on public authorities to accept them.

VAT Control Statement. The more relevant compliance requirement is the monthly VAT Control Statement (Kontrolni hlaseni), which requires detailed transaction-by-transaction XML reporting for all transactions above CZK 10,000. This covers B2B, B2G, and B2C. Late submission incurs fines of CZK 1,000-500,000.
