How to become autónomo in Spain in 2026: a step-by-step guide for foreigners

Being autónomo means working for yourself in Spain: as a freelancer, consultant, trainer, designer, shop owner and so on. Registering is mostly online and takes a few days, but foreigners have one extra step that comes first: making sure your residence permit allows self-employment.

This guide walks you through the whole process with the 2026 figures: what you pay, which forms you file, and what you must do every quarter.

Step 0: check that your permit lets you be self-employed

EU, EEA and Swiss citizens only need their registration certificate and NIE. Everyone else needs a permit that allows work por cuenta propia (self-employment). Many do, for example arraigo (except socio-training arraigo), family reunification, renewed work permits and long-term residence. Some don't, such as non-lucrative residence or a tourist stay.

We explain each permit in Which Spanish permits let you work as autónomo? If your permit doesn't allow it, registering anyway can put your residence at risk, so fix the permit first.

Step 1: get your digital ID

Almost everything is done online. You need your NIE and a way to sign in to government websites: a digital certificate (certificado digital from the FNMT) or Cl@ve. Get one of them first. It saves you appointments and queues.

Step 2: choose your activity code

The Tax Agency classifies every activity under an IAE code (epígrafe). It also decides whether you are a "professional" (for example a consultant, lawyer or designer) or a "business" (for example a shop or a taxi). This affects your invoices and your tax withholding, so choose carefully. Individuals are exempt from paying the IAE, but they still need the code.

Step 3: register with the Tax Agency (form 036)

File form 036 (declaración censal) online before you start working. The simplified form 037 was abolished in February 2025, so form 036 is now the one to use. In it you state:

• your activity code and start date;
• your VAT regime (usually the general regime, 21% standard rate);
• your income-tax method (usually estimación directa simplificada);
• where you work (home, premises or online).

Step 4: register with Social Security (RETA)

Register in the self-employed scheme (Régimen Especial de Trabajadores Autónomos, RETA) online through Import@ss. You can do it up to 60 days before you start, but no later than the day you start. In the same application you:

• ask for the €80 tarifa plana. You must request it when you register;
• estimate your monthly net income for the year, which sets your contribution bracket;
• choose a mutual insurance company (mutua) for sick leave and work accidents.

Who gets the tarifa plana: people registering as autónomo for the first time, or who have not been registered in the previous 2 years (3 years if they had the reduced rate before). It is not limited to Spanish nationals. The second 12 months are not automatic: you must ask for them before month 13, declaring that you expect your net income to stay below the minimum wage. In practice the monthly charge is about €88, because the 0.9% MEI charge is added to the €80.

What you pay in 2026

From month 13 (or month 25 if you keep the reduced rate), your monthly payment depends on your expected net income. The 2026 bases are set by Order PJC/297/2026. The total rate is about 31.5% of your base, including the 0.9% intergenerational equity charge (MEI). These are the minimum monthly payments, rounded:

"Net income" means your income minus your business expenses, minus a further 7% general deduction. You can change your bracket up to 6 times a year. After the year ends, Social Security compares your estimate with your real income from the tax return and asks for the difference or refunds it.

Step 5: premises and local licences

If you work from an office, shop or workshop open to the public, check with your town hall whether you need an activity licence or a "responsible declaration" (declaración responsable). Working online from home usually doesn't need one, but rules vary by town.

Your obligations once you are registered

• Invoices: every invoice needs your name, NIE/NIF, the client's details, a number, the date, VAT and, where applicable, income-tax withholding. Tax-compliant invoicing software (Verifactu) becomes mandatory for most autónomos from 1 July 2027 (Royal Decree-law 15/2025).
• Withholding: professionals who invoice Spanish businesses usually apply 15% income-tax withholding, or 7% in the year they start and the two years after, if they did not work as professionals the year before (tell the client in writing).
• Quarterly returns by 20 April, 20 July, 20 October and 30 January: form 303 (VAT) and form 130 (income-tax prepayment). You don't file form 130 if at least 70% of your income in the previous year had tax withheld.
• Annual returns: form 390 (VAT summary) and your personal income-tax return (Renta).
• Your residence permit: when you renew a self-employment permit, the immigration office checks that you are up to date with tax and Social Security (art. 86 RD 1155/2024).

Common mistakes to avoid

• Starting before registering. Registering late means paying contributions from the day you really started, with surcharges for the late months.
• Forgetting to ask for the tarifa plana in the registration itself.
• Guessing your income too low, then facing a large bill after the annual adjustment.
• Registering on a permit that doesn't allow self-employment. This is the most serious mistake for foreigners.
