Applies to: Common-territory Spanish VAT; Canary Islands, Ceuta, Melilla and foral cases need the appropriate separate analysis.
Before you start
- Sales and purchase invoice registers for the period.
- Previous returns and carry-forward balances.
- Your VAT registration, regime and cross-border transaction details.
- Electronic identification and chosen payment/refund information.
The steps
Confirm the return applies
Check your activity, VAT territory, regime and filing frequency. Self-employment does not mean every transaction has ordinary Spanish VAT.
Reconcile the records
Match issued invoices, credit notes, deductible input VAT and relevant intra-EU or reverse-charge items. Keep business evidence for deductions.
Choose year and period
AEAT publishes separate 2026 instructions for January/Q1 and February onward/Q2 onward. Do not copy box numbers from a 2018 tutorial.
Complete and validate
Enter the applicable figures or review imported data. Fix validation errors and have uncertain cross-border treatment assessed before filing.
Choose the settlement option
Payment, compensation and refund are not interchangeable. Direct-debit deadlines can precede the main filing deadline.
Submit and retain evidence
Sign and submit, then save the receipt and settlement proof. A saved draft or payment request alone does not establish a filed return.
Important details
Current dates
Use the live AEAT calendar for the period, including weekends and payment-method deadlines. This guide deliberately does not project an unannounced future calendar.
No activity
Check whether your registration still requires a no-activity return. Having no sales is not the same as having no filing obligation.

Pair these practical steps with the Spain-wide essentials.
