Deductible expenses for autónomos in Spain - 2025

Deductible expenses for autónomos in Spain

This guide spells out every cost you may (and may not) claim, plus the documents you need to back each one up.

What expenses can autónomos deduct in Spain? The golden rule

For autónomos, expenses as self‑employed include everything from gear to travel, as long as they’re linked to work. And you need the paperwork to back it up. If Hacienda calls, you’ll have to show proof that the expense served your business. Without that, they can reject the deduction and charge you up to 50% more tax than if you hadn’t claimed it at all.

The paperwork that proves an expense

Each category of expenses requires a different level of transaction proof - from a simple bank receipt to a full invoice that includes several identifiers.

Stronger vs. weaker proof. A stronger document always works in place of a weaker one. If the table asks for a “receipt with your name” and you have a full invoice with your name, NIE and address, that’s fine. The other way around is not.

Recovering VAT (IVA). You can reclaim input VAT only with a full invoice that includes your autónomo name, NIE and address.
