Czechia's e-invoicing deadlines

There is no domestic B2B e-invoicing mandate in Czechia. Receiving is mandatory only for public-procurement contracting authorities.

Receiving

There is no domestic B2B e-invoicing mandate in Czechia. Receiving is mandatory only for contracting authorities in scope of public procurement (B2G), under zákon č. 134/2016 Sb., from 1 April 2019 for the category "Česká republika a Česká národní banka" and from 1 April 2020 for other contracting authorities; accepted formats are UBL 2.1 (ISO/IEC 19845:2015), UN/CEFACT CII, and ISDOC/ISDOCX 5.2 or later.

Issuing

There is no domestic B2B issuing obligation either. The one obligation with a date attached is EU-wide; it is not domestic. From 1 July 2030, structured e-invoicing becomes the default for intra-EU B2B supplies under the EU’s VAT in the Digital Age package (Directive (EU) 2025/516).

Format

Where a format is required at all (the B2G channel), it is UBL 2.1 (ISO/IEC 19845:2015), UN/CEFACT CII, or ISDOC/ISDOCX 5.2 or later. No domestic B2B format is mandated because no domestic B2B mandate exists.

Channel

The B2G channel is the contracting authority’s own reception point under Act No. 134/2016 Coll.; there is no domestic B2B channel to name. EUInvoice does not connect to the B2G channel.

What this does not cover

This page does not cover public-procurement B2G invoicing in detail, and it does not track whether a domestic B2B mandate is later adopted.
