Lost with VeriFactu dates? We clarify when it really comes into force, why it has been delayed to 2027, and how to prepare your business without stress or penalties.

VeriFactu in 2027: the definitive calendar every freelancer and SME should know
VeriFactu in 2026? In 2027? Does it start in January or July? If you have been reading contradictory VeriFactu news for months, you are not the only one. Between royal decrees, ministerial orders, and political statements, many freelancers and SME owners have ended up with more doubts than certainties. And the worst part: the worry about a fine of up to €50,000 keeps them awake.
In this article, we give you the clarity you need. No overwhelming technicalities, no alarmism. Only real dates, practical consequences, and, above all, good news: adapting can be much easier than you think.
When does VeriFactu really come into force? The official calendar
The million-dollar question is "VeriFactu, when does it come into force?". The short answer: it depends on how you are paying taxes. After several regulatory changes, the Government has established a staggered calendar that postpones the obligation to 2027. These are the dates you must note in your agenda:
| Date | Who does it affect? | What changes? |
|---|---|---|
| January 1, 2027 | Companies that pay Corporate Tax (IS) | Must already use approved billing software that meets the system's requirements. |
| July 1, 2027 | Freelancers, professionals, and other companies | The obligation to issue invoices with a Computerized Billing System (SIF) adapted to VeriFactu comes into force. |
In other words, if you are a freelancer or have a small company, your key date is July 1, 2027. That is the true meaning of "VeriFactu 2027": it is not a distant and irrelevant change, but the maximum deadline you have to adapt your way of invoicing without breaking the law.
And what about software developers?
Here there is an important difference. Manufacturers of billing programs must have their products technically adapted before your deadline as a user arrives. According to the regulations, they have nine months from the entry into force of the ministerial order that develops the technical specifications. This means that, if you choose a reliable provider, their software will be ready long before you have to comply with the obligation.
Will there be any delays with VeriFactu? Rumors, politics, and reality
Another doubt circulating on social media is whether there will be more extensions. Is this VeriFactu delay definitive, or should we expect another surprise?
The reality is that the postponement announced on December 2, 2025, is already the second major calendar change. Initially, the regulation aimed for 2025, then it moved to 2026, and finally, the Government approved a royal decree-law that set the dates in 2027. The official reason was to give leeway to associations of freelancers and SMEs, who warned of the difficulty of adapting in time due to a lack of approved software and internal resources.
Should you wait until the last minute?
Our recommendation as consultants is clear: do not count on another delay. The regulations are already approved, the dates are in the BOE (Official State Gazette), and the AEAT is working on the free application for taxpayers with low billing. Taking advantage of these months to choose your billing tool is the only way to avoid last-minute chaos: collapses in consultancies, price increases for software, and, above all, the risk of continuing to use Excel or Word on the day the obligation becomes effective.
Remember: using unapproved software—what the law calls "dual-use software"—can lead to penalties of up to €50,000 per fiscal year. It's not a scare tactic; it's a figure included in the Anti-Fraud Law.
