An autónomo in Spain pays along two independent lines: a monthly contribution to the Seguridad Social (social security) — from €200 in the lowest bracket — and taxes to Hacienda (the tax authority): IRPF (income tax) in quarterly advance payments and IVA (VAT) on invoices issued. The contribution is paid even in a month with no income; tax is paid only on profit.
In the first year there is a reduced rate: €80 a month instead of the full contribution. But you must claim it at the time of registration itself — it cannot be applied retrospectively, and people lose several thousand euros this way.
How to get the status and register is covered in the article on being autónomo in Spain. Here we look at what happens after registration.
Two lines of payments
| Seguridad Social | Hacienda | |
|---|---|---|
| What it is | a contribution, not a tax | taxes |
| Frequency | monthly | quarterly and annually |
| Depends on income | yes, via the bracket | yes, directly |
| Paid in a loss-making month | yes | no |
| What it gives you | healthcare, contribution record, sick pay, pension | — |
| Deductible from the tax base | yes, in full | — |
The Seguridad Social contribution is the only compulsory payment that itself reduces your tax. People forget this when calculating the burden: the real cost of the cuota (contribution) is lower than its face value by the amount of IRPF saved.
Cuota: the system based on actual income
Since 2023 the contribution has depended on net profit: profit determines the bracket, and the bracket determines the amount.
The minimum contribution for 2026 in the lowest bracket, for income below €670 a month, is €200 a month; the first three brackets are frozen for 2026. The usual contribution ranges from roughly €230 to €540 a month depending on which bracket you fall into.
The mechanics you need to understand straight away:
- You forecast your net profit and pay according to the forecast.
- At the end of the year the Seguridad Social compares the forecast with data received from Hacienda.
- A recalculation is made — an extra payment or a refund.
You can change your base up to six times a year. It is worth using this: underestimate your forecast and you will get a lump-sum bill at the end of the year; overestimate it and you give the state an interest-free loan all year.
Tarifa plana: where people lose thousands of euros
How much. €80 a month for the first 12 months regardless of income. With the mandatory MEI surcharge the actual payment is about €88.72 a month.
Extension. Another 12 months at the same price if your net income for the second year does not exceed the annual minimum wage (SMI).
Savings. In the first year, €1,800 to €5,500 depending on which bracket you would have fallen into without the reduced rate. With a successful extension, the combined savings over two years approach €10,000 for the highest-earning profiles.
Conditions
- not having been registered in RETA (the self-employed social security scheme) in the previous two years — three if you have used the reduced rate before;
- not being an autónomo colaborador (a family member working in the business);
- having no debts to the Seguridad Social or Hacienda.
Exactly where money is lost
The reduced rate is claimed at the moment of registration — on form TA.0521 or through the DUE (single electronic document). It cannot be applied retrospectively.
Someone registers on their own, does not tick the right box and discovers the loss a month later when the first €230 direct debit arrives. It cannot be recovered.
What it can be combined with
The reduced rate can be combined with regional cuota cero (zero contribution) programmes in a number of autonomous communities. Together, the contribution can drop to zero. Check your own region separately: the rules and deadlines differ everywhere.
Separately: an autónomo who is the director of their own SL — an autónomo societario — is also entitled to the reduced rate on the general terms. It used to be different, and older articles still say that societarios do not get it.
Three ways to calculate income, not one
This is something hardly ever covered in Russian, even though the choice affects both the amount of tax and the volume of bookkeeping.
| Method | How income is calculated | Who it suits |
|---|---|---|
| Estimación directa normal | actual income minus actual expenses, full accounting | large turnovers; the most accurate method |
| Estimación directa simplificada | the same, but with simplified bookkeeping and an extra deduction | most freelancers and small autónomos |
| Estimación objetiva (módulos) | income is calculated from objective parameters of the activity rather than actual figures | certain activities on a ministerial list |
The simplified regime was created precisely so as not to force a small business owner to keep accounts under the Commercial Code. How to register as autónomo in the first place is a separate step-by-step guide. The módulos regime goes even further: income is determined by the number of employees, the size of the premises, the capacity of equipment and other objective parameters — regardless of how much you actually earned. How to register and what to file at the start is in the guide to registering as self-employed in Spain.
A deduction for expenses you cannot prove
The simplified regime has a benefit that nobody writes about in Russian: 7% of net income is written off as “expenses that are difficult to justify”, up to a maximum of €2,000 a year. Without a single receipt.
It is a direct counterpart to the flat €2,000 deduction that employees get. For an autónomo with a profit of €30,000 a year, this is €2,000 off the tax base — about €500 of tax saved every year.
What you can deduct
- rent and utilities for work premises;
- internet, phone, hosting, software, professional subscriptions;
- professional insurance, the services of a gestor (accounting and administrative adviser) and a lawyer;
- equipment — through depreciation under the straight-line tables, not in one go;
- training related to your activity;
- meals in restaurants and cafés when related to the business, within the set limits;
- contributions to professional mutual insurance funds up to the amount corresponding to the regime;
- the cuota de autónomos itself — in full.
There is one condition: a factura (invoice) with your NIF (tax number), the date and the purpose of the payment. A supermarket receipt, a screenshot of a transfer or a verbal agreement will not do.
Working from home
If you work from your flat, part of the utility costs can be deducted, but not directly in proportion to floor area. A two-step formula applies: first the share of floor area used for work is calculated, and then a set percentage of that share is applied. The premises must be declared to the tax authority as the place where the business is carried out.
The car: the biggest disappointment
A vehicle used for both personal and business purposes is, as a rule, not considered part of the business. Full business use is presumed only for certain categories: goods and mixed-use vehicles, passenger transport vehicles, vehicles of sales representatives and a few others.
An ordinary car that you use both to visit clients and to go on holiday cannot be deducted — neither in full nor by half. This is the most common mistake new autónomos make.
Filing calendar
| Form | What it is | When |
|---|---|---|
| modelo 130 | IRPF advance payment, 20% of cumulative profit | 20 April, 20 July, 20 October, 30 January |
| modelo 303 | quarterly IVA | the same dates |
| modelo 349 | transactions with counterparties within the EU | monthly; quarterly while transactions do not exceed €50,000 |
| modelo 390 | annual IVA summary | January |
| modelo 347 | counterparties with a turnover above €3,005.06 a year | February |
| modelo 100 | annual income tax return | April–June |
Modelo 130 is not a separate tax but a prepayment of your annual IRPF. Everything paid is credited in the annual return.
An important exception: if your clients are Spanish companies or other business owners, they withhold IRPF from your invoices themselves. The general withholding rate for professional services is 15%, and for new professionals 7% in the year they start and the following two years. If withholding applies to most of your invoices, you may not need to file form 130 at all.
A practical tip. Set aside not 20% but 23% of profit. The difference goes towards the annual recalculation, which almost always goes in the tax authority’s favour: advance payments are calculated with a simplified formula, while the annual return uses the full one, including the regional part of the scale.
It is also worth comparing this with digital nomad taxes: those who move on a digital nomad visa are entitled to a special regime with a 24% rate, but it is built around an employment relationship with a foreign company and is generally not available to a freelance autónomo. Choose your form of employment before applying for the visa.
How much you take home
A freelancer in the second year of activity, with a net profit of €3,000 a month and clients in EU countries:
| Item | Per month |
|---|---|
| Cuota for the bracket | about €390 |
| IRPF advance (modelo 130, 20%) | about €520 |
| Gestor | €60–90 |
| Left over | about €2,000 |
The annual return shifts the result either way: deductions, marital status, children and regional tax breaks have a significant effect. Someone with two children and a mortgage on the same income will get a noticeably different result.
Six mistakes
- Not claiming tarifa plana at registration. The reduced rate cannot be applied retrospectively — this is the most expensive mistake at the start.
- Underestimating your income forecast. At the end of the year a recalculation for all the months will arrive at once.
- Trying to deduct your car. With mixed use it is not considered part of the business.
- Collecting receipts instead of facturas. Without a NIF and the purpose of payment the expense will not be accepted.
- Setting aside 20% and considering the matter closed. The annual recalculation usually requires an extra payment.
- Forgetting that registration affects your tax residence. Registering with the Seguridad Social is a strong argument that your centre of economic interests is in Spain, even if you have lived here for less than 183 days.
Frequently asked questions
How much does an autónomo pay in Spain?
Two lines: a Seguridad Social contribution from €200 a month in the lowest bracket up to about €540 in the highest, plus IRPF advance payments of 20% of profit and IVA. In the first year the contribution is about €88.72 under the tarifa plana reduced rate.
Do you have to pay the cuota in a month with no income?
Yes. The contribution does not depend on revenue — income only determines the bracket. If there is no activity at all, autónomos deregister and re-register later.
Can you get tarifa plana again?
Yes, if at least three years have passed since you last used it and you have not been registered in RETA for two years.
What expenses can you deduct?
Rent and utilities for work premises, communications and software, insurance, gestor services, equipment through depreciation, training related to your activity, meals within the set limits and the cuota itself in full. Each item must be supported by an invoice with your NIF.
Can you deduct a car?
With mixed personal and business use, as a rule, no. Full business use is presumed only for certain categories of vehicle, such as goods and commercial vehicles.
What is the 7% deduction?
Under the simplified income calculation regime, 7% of net income is written off as expenses that are difficult to justify, up to a maximum of €2,000 a year and without supporting documents.
Is a gestor compulsory?
Not by law. In practice returns are filed electronically, deadlines are strict and penalties for mistakes are real. The cost of the service usually pays for itself with the first incorrectly filed 303.
Which is better — autónomo or SL?
Roughly, up to a profit of about €40,000 a year being autónomo is better: an SL has higher administrative costs. Above that level it is worth calculating individually, and the result depends on whether you take the profit out or reinvest it.
Does autónomo status affect tax residence?
Yes. Registration with the Seguridad Social creates a strong argument that your centre of economic interests is in Spain, even if you stay less than 183 days. The criteria and evidence are covered in the article on tax residence in Spain.
Summary
- Two independent lines: the Seguridad Social contribution and taxes to Hacienda.
