High risk
The date, the volume and the state of adaptation point to the same next step.
This free calculator estimates your VeriFactu penalty risk in Spain. Answer four questions about your situation and get risk guidance before the 2027 deadlines (1 January 2027 for companies, 1 July 2027 for the self-employed). No sign-up, no email, no card.
Indicative only: it is not tax or legal advice.


The calculator does not try to determine a penalty. It organises the answers worth having clear to know whether you should act now.

The result is guidance based on your answers. How the penalty regime applies depends on the facts and on the Administration’s assessment.
Each choice changes a specific part of the result. You see the relationship before accepting any figure.
The tool separates level, deadline and next step so that an isolated range does not look like an official penalty.
| Level | HIGH | Steps still pending |
|---|---|---|
| Deadline | 01·07·27 | Self-employed · reference date |
| Next step | PLAN | Certificate + compliant software |
Educational guidance · Not an AEAT assessment
The date, the volume and the state of adaptation point to the same next step.
The date differs between a company and an individual.
Certificate, software and calendar must tell the same story.
For a legal answer, ask your adviser.
VeriFactu is regulated by Royal Decree 1007/2023 (RD 1007/2023). For the penalty regime, the reference is art. 201 bis of the Ley General Tributaria.

Straight answers on the calculation, its limits and the dates you need to keep in mind.
Back to the VeriFactu guide →No. The calculator is indicative: it gives you an estimated exposure range for your profile, not an assessment. The actual amount of a penalty is set by the AEAT (Spanish Tax Agency) under art. 201 bis of the Ley General Tributaria (LGT, the General Tax Act). For your specific case, ask an adviser.
From four factors: your tax situation, the invoice volume (which scales the base €10,000 / €25,000 / €50,000), whether you already comply with VeriFactu and when you plan to adapt. Combining them places you at low, medium, high or critical risk.
Companies (sociedades) are bound from 1 January 2027; the self-employed and other individuals, from 1 July 2027. Working with compliant software before your date reduces the risk of the specific infringement for using non-compliant software. Confirm your case with an adviser and see the legal detail on the VeriFactu penalties page.
Cofactu handles the XML, the signature and the submission to the AEAT so you can focus on your business.
