Becoming autonomo in Spain: costs, tax and registration.
Spain's self-employed status is cheap to start, contribution-banded by what you actually earn, and carries a quarterly rhythm most newcomers discover late. Here is what it costs, how you register, and when a company is the better answer.
What is an autonomo?
Autonomo is Spain's self-employed status: a natural person carrying on an economic activity in their own name. It is not a company and creates no separate legal personality, so there is no liability shield between the business and the individual. Registration involves two steps — a tax registration with the tax authority and enrolment in the self-employed social security scheme, RETA.
For freelancers, consultants, remote workers and anyone testing an idea, autonomo is the natural starting point in Spain. It is quick to set up, cheap in the first year, and reversible. Its weaknesses are equally clear: unlimited personal liability, contributions payable whether or not you earn, and a tax rate that climbs with your income rather than sitting flat.
Who can register.
Immigration status decides whether autonomo is available at all.
A residence permit that allows employment does not automatically allow self-employment, and a student permit generally allows neither without authorisation. Registering as autonomo on a permit that does not cover it is not a paperwork error — it is working outside your authorisation. Confirm the permit first, then register.
What it actually costs.
Since the 2023 reform, self-employed social security contributions are banded by real net earnings rather than being a flat choice. You forecast your net income, that places you in a band, and the year is regularised afterwards against what you actually earned.
| Situation | Monthly contribution | Notes |
|---|---|---|
| First year, reduced rate | About 89 EUR | The 80 euro tarifa plana plus the intergenerational equity charge |
| Second year, if earnings below minimum wage | About 89 EUR | Extension of twelve further months, on application |
| Reduced table, lower earnings | From around 200 EUR | Bands 1 to 6, for net earnings up to about 1,700 EUR a month |
| General table | Rising to around 590 EUR | Bands 7 to 15, from about 1,700 EUR a month upward |
| Intergenerational equity mechanism | 0.9% in 2026 | Applies on top of every band, adding roughly 7 to 15 EUR a month |
Who gets the reduced rate
Broadly, those not registered in RETA during the previous two years — three if the reduction was used before — and with no outstanding debts to social security or the tax authority. Certain groups, including people with a disability of 33% or more, access longer periods.
It is not a tax, and it is not optional
The contribution is due for every month you are registered, regardless of whether you invoiced anything. Deregistering during a quiet period is possible, but re-registering resets nothing and can affect the reduced rate.
The contributions are deductible against your professional income, which softens the headline figure. They also buy real cover: healthcare, sick pay, pension accrual and, subject to conditions, a cessation-of-activity benefit.
How to register, step by step.
The quarterly rhythm nobody mentions.
This is where newcomers are most often caught out. Spanish self-employment is not an annual affair. You pay income tax on account four times a year and, in most cases, file VAT on the same cycle.
| Filing | What it is | Frequency |
|---|---|---|
| Modelo 130 | Payment on account of income tax | Quarterly, where direct estimation applies |
| Modelo 303 | VAT return | Quarterly |
| Modelo 390 | Annual VAT summary | January |
| Modelo 349 | Intra-community transactions | Periodic, if you have EU business clients |
| Modelo 100 | Annual income tax return | Spring |
| Modelo 720 | Assets held abroad above the threshold | Annually — frequently forgotten by newcomers |
| Modelo 111 / 115 | Withholding on professionals or rent | Quarterly, if applicable |
Withholding on your own invoices, and the retention you must apply.
Spanish professionals commonly show an income tax retention on invoices issued to Spanish businesses, which the client withholds and pays over on your behalf — so you receive less than the invoice face value and credit it later. Separately, if you pay Spanish professionals yourself, you may have to withhold and file. Neither has an equivalent in most other countries, and both catch people in their first quarter.
What you can deduct.
- Social security contributions — fully deductible against professional income
- Professional services — accountancy, legal, advisory
- Equipment and software used for the activity
- Home office costs — a proportion of utilities where the activity is declared at home, on a defined basis
- Travel and subsistence — with strict evidence requirements and daily limits
- Vehicle costs — heavily restricted for professionals, and a frequent point of dispute
- Health insurance premiums — within annual limits, for you and dependants
- Training related to the activity
The recurring theme is evidence. Spanish practice expects an invoice in the name of the autonomo, a demonstrable link to the activity, and payment traceable through a business account. An expense that is real but undocumented is treated the same as one that is not real.
Autonomo or a company?
The honest comparison, without the usual hand-waving about a magic income threshold. There is no single figure at which a company becomes better, because the answer depends on how much profit you retain rather than on turnover.
| Autonomo | Spanish SL | |
|---|---|---|
| Setup cost and time | Low, days | Higher, six to ten weeks |
| Liability | Personal and unlimited | Limited to the company |
| Tax on profit | Progressive personal scale | Corporate rate, with reduced rates for smaller and new companies |
| If you draw everything out | Simpler and often cheaper | Corporate tax then dividend tax on the same profit |
| If you retain profit | Taxed personally regardless | Retained at the corporate rate |
| Credibility with clients | Adequate for most | Expected by corporate and public buyers |
| Ongoing admin | Lighter | Two authorities, annual accounts, registry filings |
| Impatriate regime access | Generally excluded | Depends on the engagement, not automatic |
Draw it all out, stay autonomo. Retain it, consider a company.
If every euro of profit ends up in your personal account each year, a company adds a layer of tax and administration without changing the outcome much. If a meaningful share stays in the business to fund growth, the corporate rate does real work. Liability and client expectations can override the arithmetic in either direction.
The trap for new arrivals.
It generally closes the impatriate regime
Spain's special regime for new arrivals taxes qualifying employment income at a flat rate for several years. Self-employed people with commercial client relationships are generally outside it. Registering as autonomo because it is the fast option can therefore forfeit a substantial benefit — permanently, because the election window is short.
Test eligibility before you register anything
If you are newly arriving in Spain with income from abroad, establish whether the impatriate regime is available to you and what contract structure it would require, before defaulting into self-employment. That analysis takes days; the consequence of skipping it lasts six years.
