VeriFactu for autónomos explained (2026): what it is, the new 2027 deadline, and what to do now

If you invoice as an autónomo in Spain, VeriFactu is the change that decides which software you can use. It has been announced, delayed, and delayed again, so most explanations you find are out of date. Here is the state of play as of September 2026, and the boring, cheap way to be ready.

What VeriFactu actually is

The framework comes from Spain’s 2021 anti-fraud law and the 2023 regulation on invoicing-system requirements (usually called the SIF regulation), with the technical detail in a 2024 ministerial order. It sets rules for the computer systems businesses use to issue invoices:

• Integrity: every invoice record is hashed and linked to the previous one, so nothing can be edited or deleted without leaving a trace.
• Traceability: an event log records what the system did and when.
• The QR code and the legend: each invoice carries a QR code the customer can scan to check it, and a “VERI*FACTU” legend when the system sends records to the tax agency.
• Two modes: a VeriFactu system sends each invoice record to the AEAT as it is issued; a non-VeriFactu system keeps the same certified records locally and hands them over on request. Sending is voluntary but the tax agency treats it as the default expectation.
• Software makers must certify their products with a declaration of responsibility. “Dual-use” software that can hide sales has been illegal since the 2021 law regardless of the deadline.

What it is not: it is not the B2B electronic-invoice exchange mandate (the “Crea y Crece” reform). That one concerns the structured format and platform through which businesses exchange invoices, and its final regulation is still pending. Both will apply eventually; VeriFactu is the one with a date.

The timeline, and why it keeps moving

The Ministry’s stated reason for the latest delay is to give software vendors and businesses time to adapt in an orderly way. The postponement changes the date only: the technical requirements, the certification duty for vendors and the anti-fraud rules stay exactly as they were. Dates have moved twice, so check the AEAT page before you plan around them, but do not read the delay as “it will never happen.”

What it means for a one-person business

For an autónomo the practical consequences are smaller than the noise suggests:

1. You need a certified tool. Most Spanish invoicing and accounting programmes are shipping VeriFactu modes; the shortlist for Spanish autónomos is built around that. The tax agency also offers a free basic application, which works if you issue few invoices and do not need anything else.
2. Your invoice content does not change much. The fields a legal invoice needs are the same ones covered in how to invoice clients as a freelancer in the EU; VeriFactu adds the QR code and the legend, which the software prints for you.
3. Corrections work differently. You cannot silently overwrite an issued invoice. Mistakes are fixed by a rectifying invoice (factura rectificativa), which the system records as a new event. Get used to that habit now — it is also what a clean audit trail looks like.
4. Foreign clients are unaffected by the format, but still go through the system. A reverse-charge invoice to a German company is still produced by your certified programme. The VAT logic itself is the normal one: see reverse-charge VAT explained.

The cheap way to be ready

• If you are starting now: pick a certified tool from day one. It is the same monthly fee you would pay anyway and removes the migration entirely. The full setup order is in becoming an autónomo in Spain.
• If you already invoice from a tool: check whether your vendor has published its VeriFactu declaration and when the mode ships. If the answer is vague, plan a move.
• If you invoice from Excel or Word: you have until mid-2027, but the numbering, client data and templates are easier to migrate now than under pressure.

And step back from the software for a second: VeriFactu is one country’s version of a Europe-wide move toward structured, verifiable invoicing. The map of who mandates what, and when, is in EU e-invoicing mandates by country.

The takeaway

• VeriFactu = certified, tamper-proof invoicing software with a QR code and an optional real-time feed to the tax agency. Not a new tax, not the B2B exchange mandate.
• Deadline now 1 July 2027 for autónomos, 1 January 2027 for companies. Verify on AEAT; it has moved before.
• Spreadsheets will not qualify. A certified tool is cheap; the migration is what costs time, so do it early.
