Modelo 303 step by step: the quarterly VAT return in Spain

2026-11-04

Modelo 303 is the quarterly VAT (IVA) return. It is filed in April, July and October (by the 20th) and in January (by the 30th).

How it is worked out

Item What it includes
Output VAT (IVA repercutido) The VAT on the invoices you have issued
Deductible input VAT (IVA soportado) The VAT on the expense invoices you can deduct
Result Output minus input: what you pay or get back

If you buy services from a supplier outside the EU, the invoice arrives without VAT and you declare and deduct it at the same time: this is the reverse charge (inversión del sujeto pasivo).

Indicative only: confirm your case with your accountant.
