e-Factura Rejected by ANAF: Common Causes and How to Fix It

A rejected e-Factura is not a transmitted invoice: ANAF found a validation error and the document must be fixed and resent. The good news is that the error message usually says exactly what’s wrong.

Common causes of rejection

• Wrong or non-existent CUI/CIF — the client’s tax code is not valid, or its VAT status is marked incorrectly (with/without the RO prefix).
• Incorrect VAT rate — a rate that doesn’t match the category, or a VAT amount that doesn’t match the base.
• Missing mandatory fields — address, unit of measure, description. See the mandatory elements.
• Totals that don’t match — the sum of the lines doesn’t equal the total, due to rounding.
• B2C identification data — for sales to individuals, a missing consumer code.

How you read the error

ANAF returns a file with the validation errors. Each error usually indicates the field and the rule that was violated. Don’t be discouraged by the technical language — it’s usually a single, specific fix.

How you avoid rejections

The most effective approach is to catch errors before sending: local structure validation, a verified CUI, correct VAT rates from the start.

How facturifirma helps

facturifirma validates the structure before sending, so you catch missing fields locally. If ANAF still rejects the invoice, the error message is displayed directly on the document — you see exactly which field needs fixing, correct it and resend the same invoice, without a new series or number.
