Autónomo Taxes in Spain Explained for Foreign Freelancers

Working for yourself in Spain means entering the world of the Autónomo. Whether you are a freelance graphic designer, an IT consultant, or a private English teacher, registering as an autónomo is a legal requirement if you are performing economic activities independently.

The Spanish tax system for freelancers is notoriously complex. Here is a breakdown of what you actually have to pay.

1. The Social Security Quota (Cuota de Autónomos)

Unlike many countries where you pay social security as a percentage of your end-of-year profits, Spain requires a fixed monthly payment, regardless of whether you made €10,000 that month or €0.

Recently, the system transitioned to a "real income" model. You must estimate your net monthly income and pay a quota corresponding to that income bracket.

• In 2026, the lowest tier (earning under €670/net month) pays around €200/month.
• The highest tier (earning over €6,000/net month) pays over €590/month.

2. IVA (Value Added Tax)

Impuesto sobre el Valor Añadido (IVA) is currently 21% for standard services. When you invoice a client within Spain (and often the EU, depending on VAT registration), you must add 21% IVA onto your invoice.

This is not your money. Every quarter, you must submit the Modelo 303 return and pay the IVA you collected to the Hacienda (tax authority). You can, however, deduct the IVA you paid on business-related expenses (like your laptop or internet bill) from the IVA you owe.

3. IRPF (Income Tax)

IRPF is your standard income tax. As a freelancer, you don't have an employer withholding tax from your paycheck. Instead, you pay it quarterly in advance via Modelo 130. You generally pay 20% of your net profits every quarter as a prepayment of your income tax.

When you file your annual tax return (la Declaración de la Renta) the following spring, the Hacienda calculates your actual tax bracket based on your total yearly earnings. If your 20% quarterly prepayments were more than your final tax liability, you get a refund. If less, you must pay the difference.

"Attempting to navigate Spanish IVA and IRPF quarterly filings without a gestor (accountant) is incredibly risky. The fines for late or incorrect filings start at 50% of the owed amount."

Retenciones on Invoices

If you invoice another Spanish business or professional, you must include an IRPF retención (usually 15%, or 7% for your first three years) on the invoice. This means the client pays you less than the total invoice, and they pay that 15% directly to the tax office on your behalf.
