E-invoicing in Romania: RO e-Factura, RO_CIUS, mandate

Romania rolled out e-invoicing through its national RO e-Factura system early. Since 1 July 2024 it is mandatory for B2B and B2G, for Romanian taxpayers and foreign companies with a fixed establishment in the country. The format is RO_CIUS, a profile of EN 16931, submitted through the SPV with a 5-day deadline.

TL;DR

Mandatory since 1.7.2024 for B2B and B2G, B2C reporting since January 2025. Format: RO_CIUS (EN 16931, UBL 2.1 or CII). Submitted via RO e-Factura in ANAF's SPV, deadline 5 calendar days. Specific: a county code (Județ) as CountrySubentity. Vera produces the RO_CIUS file; submission to RO e-Factura is separate.

Format and RO e-Factura

The format is RO_CIUS, a Romanian CIUS of EN 16931, as XML in UBL 2.1 or CII. The invoice is submitted through the national RO e-Factura system, reached in the Spațiul Privat Virtual (SPV) of ANAF. The deadline is 5 calendar days from invoice issue.

Note: Vera produces the valid RO_CIUS file but does not submit it to RO e-Factura itself. The submission in the SPV and the 5-day deadline are handled through the national system.
