How to run a Spanish tax, Verifactu and VAT audit, step by step
- Confirm what applies. Confirm whether the company is in the SII (turnover above €6 million) or must use Verifactu from 2027. The Basque Country and Navarre have their own systems (TicketBAI).
- Walk the site, standard by standard. Score each of the 13 checkpoints Pass, Fail or N/A. N/A only where the standard rules it out, with the reason recorded. Ask the DMS provider for the Verifactu certificate, then review 20 invoices, 10 REBU sales, 10 registration tax returns (form 576), 5 intra-EU sales and the SII dashboard.
- Capture the evidence. A pass counts only with proof captured at the time of the audit: the software provider's responsible declaration, invoices, purchase invoices for REBU cars, form 576 returns, VIES checks and CMR transport documents, and the SII report.
- Give every fail an owner and a fix time. Record what you saw and who owns the fix. Each standard carries an ideal fix time, from 72 hours to 30 days, counted from audit submission (see the table above).
- Fix it, then prove it. The site fixes the cause and uploads proof of closure; the auditor checks the proof before closing the finding.
- Re-check at the next audit. Confirm closed findings stay closed, and look for the same fail at your other sites so one gap doesn't repeat across the network.
