Within how many days must an invoice be sent to e-Factura in 2026?

The deadline moved from calendar days to working days, which changes the arithmetic in any week with a public holiday. The difference is practical: an invoice issued on a Friday no longer expires on the Wednesday.

Short answer

The deadline for transmission to the RO e-Factura system is 5 working days from the invoice date.
It cannot exceed 5 working days from the statutory deadline for issuing the invoice.
Working days exclude Saturdays, Sundays and public holidays.
The rule comes from OUG 89/2025, which amended art. 10 para. (7) of OUG 120/2021.
An invoice counts as transmitted when the system receives it, not when the XML file is generated.

What the law says

OUG 120/2021 governs the national RO e-Factura system, and art. 10 para. (7) sets the transmission deadline.
The amended text provides for 5 working days from the invoice date, but no later than 5 working days from the invoicing deadline in art. 319 para. (16) of the Fiscal Code.
The statutory invoicing deadline is, as a rule, the 15th day of the month following the chargeable event.
The period runs from the issue date, not from the date the invoice was booked.
Exceeding the deadline is an offence distinct from failing to transmit at all.

Practical examples

An invoice issued on Monday 5 October is due by Friday 9 October, absent a public holiday.
An invoice issued on a Friday is due by the following Thursday: Saturday and Sunday do not count.
In a week containing a public holiday, the deadline extends by one further calendar day.
An invoice for a 20 September supply, issued on 15 October, meets both deadlines if it reaches the system within 5 working days of 15 October.

Common mistakes

Counting calendar days under the old rule and missing the deadline in weeks with holidays.
Generating the XML on time but never uploading it — the deadline refers to receipt by the system.
Not checking the status after upload: an invoice rejected on validation errors does not count as transmitted.
Leaving transmission to the last day, with no margin to fix a validation error.

How 4conta helps

4conta transmits invoices to RO e-Factura through the ANAF private-space integration right after issue, so the five-working-day deadline never becomes a constraint. The working-day calendar includes public holidays, and untransmitted invoices appear in a separate list ordered by remaining time.

The status returned by ANAF is attached to the invoice: a validation rejection is flagged and resent after correction, rather than silently passing as transmitted.
