One minute, no sign-up, no small print: we tell you whether you are in scope, your exact date and the recommended fix for your case — online store, ERP, POS or custom application. With the only firm dates in the calendar: 1 January 2027 (companies) and 1 July 2027 (self-employed).
Tick what applies; the result appears on its own. If a question stops being relevant to your case (say, you are a software maker), the result shows earlier.
We email you this result. If Spain's official Verifactu calendar moves — it already happened once — we let you know. No weekly emails.
This is general information, not tax advice: the result guides the general case and does not replace your advisor. Dates from the official calendar in force (RD 1007/2023 and its December 2025 postponement).
From Spain's invoicing-software regulation (RD 1007/2023, anti-fraud Law 11/2021) and its calendar in force after the postponement approved in December 2025: 1 January 2027 for corporate-tax payers and 1 July 2027 for the self-employed and other obligated parties. Those are the only firm dates; anything else you may read comes from earlier drafts. The full explanation, with the table by situation and the FAQ, is in the guide “Who must comply with Verifactu, and when?”.
It is free and the full result shows on screen without leaving any data. Only if you want it by email (plus the alert if the calendar changes) do we ask for your address, with double opt-in confirmation and one-click unsubscribe.
Your answers stay in your browser. If you request the result by email, we store your address and your case so we can alert you if the official calendar changes; nothing else and no sharing. Data controller: Softnet Sistemas S.L. (Alicante, Spain).
It guides the general case based on the regulation and the tax agency FAQ, but it is general information: cases with nuances (multiple activities, several territories, partial SII) should be confirmed by your advisor. Write to us and we will look at yours for free.
Multiple companies, several territories, a program you are not sure complies… write to us and we will tell you what we would do, free and with no strings attached.
