Veri*Factu and Real-Income Contributions: The 2026 Tax Changes Freelancers and SMEs Shouldn’t Leave Until December

The second half of July is always a deadline month for freelancers and small businesses: July 20 marks the close of the filing window for VAT and the personal income tax installment payments corresponding to the second quarter of 2026. But beyond that recurring date, this year brings two deeper changes worth getting ahead of before they arrive in a rush: the rollout of verifiable electronic invoicing (Veri*Factu) and the consolidation of the self-employed contribution system based on real income.

Veri*Factu moves from proposal to requirement

The regulation requiring invoicing software to be “verifiable” by Spain’s Tax Agency — popularly known as Veri*Factu — has already moved into active enforcement for companies, and throughout 2026 it’s the turn of the remaining taxpayers, including most freelancers who invoice through software. In practice, this means invoicing programs must generate tamper-proof records of every invoice, complete with a chained electronic fingerprint, and send that information to the Tax Agency (or have it ready to send) at the moment of issue. Systems that fall short of these requirements — spreadsheets dressed up as invoicing tools, loose templates, outdated software that was never updated — are now outside the law, and using them can trigger penalties both for the business issuing the invoices and, in certain cases, for the software provider itself.

On top of this, the “Crea y Crece” Act continues on its own timeline toward mandatory electronic invoicing between businesses and freelancers (B2B), with different deadlines depending on turnover — which in practice will run in parallel with Veri*Factu over the coming years. They’re not the same obligation, but they share the same underlying logic: full traceability and less room for undeclared income.

Real-income contributions: the brackets keep shifting

The system that ties self-employed Social Security contributions to actual net earnings continues to evolve, with brackets reviewed every year that set the minimum and maximum applicable contribution base. Anyone who earned more or less in 2025 than they estimated when choosing their bracket could face a contribution adjustment — a refund or an extra charge — once Social Security cross-checks the figures against their income tax return. It’s an automatic process, but it’s worth checking in advance which bracket you’re in and whether your actual 2026 earnings are drifting from your original estimate, so you can adjust your contributions before the correction lands on its own — sometimes with a surcharge attached.

Alongside this, the Tax Agency is keeping up the pressure on late filings: surcharges apply for late submissions made without a prior notice, and penalties get considerably steeper once the Agency has already sent a formal request. The AEAT has also strengthened automatic cross-checking between forms — VAT, withholdings, installment payments and the annual returns themselves — so mismatches between what’s declared quarter by quarter and the annual summary forms (390, 190) now get flagged far faster than they used to.

What this means for your business

If you’re self-employed or run an SME, there are concrete decisions worth making now, not in December. First, check whether your invoicing software — or your accounting firm’s — is already Veri*Factu-ready or has a firm date for the update: switching software at the last minute, while the business is running, is the fastest way to end up with bad invoices or duplicate records. Second, review the contribution bracket you chose in light of how 2026 is actually going: if your net income is running above what you projected, adjusting your base now avoids an unpleasant correction next year. Third, don’t leave the quarterly forms for the last day: with the level of cross-checking the AEAT now runs, a slip on a quarterly VAT or income tax form shows up in the annual summary, and explaining it after the fact costs more time — and sometimes money — than filing it correctly the first time. And fourth, if your business is approaching the turnover thresholds that trigger mandatory B2B e-invoicing, start asking your software providers and key clients how they plan to handle it, because getting ready isn’t something you can do alone.

At Zythos Business, this is exactly where we support freelancers and SMEs: turning every regulatory change — Veri*Factu, real-income contributions, AEAT cross-checks — into concrete decisions about software, contributions and deadlines, so that a new tax rule doesn’t turn into an accounting surprise six months down the line.
