Self-Employed Contribution 2026: Income Brackets and What's New

For decades, Spanish self-employed workers picked their contribution base rather as one picks a mobile plan, and the overwhelming majority picked the minimum. The result was a generation of sole traders with very low pensions. The actual-income contribution system, in force since 2023, aims to correct that by tying what you pay to what you genuinely earn.

The new actual-income contribution system

Since January 2023, self-employed workers in Spain contribute based on their actual net income, not a freely chosen base. The system is being phased in progressively: 2023, 2024 and 2025 had transitional rates; in 2026 the definitive structure with 15 brackets takes full effect.

The mechanics are simple to describe: you work out your expected monthly net income, find the bracket it falls into, and contribute on that bracket's minimum base, to which a rate of around 31.4% is applied. You may choose a higher base if you want to improve your future benefits, but never one below the bracket that applies to you.

How is net income calculated?

Net income = total business income − tax-deductible expenses. For self-employed on direct assessment: income − actual expenses. For module-based (objective assessment): according to activity modules. A further generic-expenses deduction of 7% then applies as a general rule, falling to 3% for self-employed company directors.

The gap between turnover and net income causes the most confusion, and it is not a small one. If you invoice €3,000 a month with €1,000 of deductible expenses, your income before the generic deduction is €2,000; applying the 7% (€140), the net income that sets your bracket comes to €1,860. You do not contribute on the €3,000 invoiced, but on that result.

Worked example

Take that same worker with €1,860 of monthly net income. That amount falls in the €1,850–2,030 bracket, whose minimum base is around €1,209. Applying the 31.4% rate, the estimated monthly contribution is about €380 — roughly €4,560 a year. Were they to choose a higher base to improve their future pension, the contribution would rise proportionally.

Flat rate for new self-employed workers

New self-employed workers can apply for the €80/month flat rate for the first 12 months. In autonomous communities with their own bonuses (such as Madrid or Murcia) this can extend to 24 months. To qualify, they must not have been registered with the RETA in the previous 2 years.

After those first twelve months, the flat rate can be extended for another year, but only if your net income stays below the national minimum wage. It is a condition worth bearing in mind from the outset: if your business takes off sooner than expected, you will lose the discount precisely as you start earning more.

Annual regularisation

During the year a provisional contribution is paid based on estimated income. The following year, Social Security cross-checks with the tax authority: if you earned more than estimated, you pay the difference; if less, you receive a refund. It is important to declare a realistic estimate to avoid surprises.

The existence of regularisation takes the drama out of getting your initial forecast wrong, but it is no reason to stop paying attention. You can change your base up to six times a year, taking effect every two months, and that flexibility exists precisely because self-employed income fluctuates. Reviewing your numbers a couple of times a year avoids a several-thousand-euro reconciliation bill nobody budgeted for.

What the contribution actually covers

• •Healthcare for you and your dependants
• •Temporary incapacity through ordinary illness or accident
• •Occupational contingencies (workplace accident and occupational disease)
• •Cessation of activity, the equivalent of unemployment benefit for employees
• •The contributions that build your future retirement pension

Since 2019 all these coverages have been compulsory, where several used to be optional. That is why the contribution went up — but also why a self-employed worker today is considerably better protected than one a decade ago. And it is worth remembering that always contributing on the minimum base makes the monthly bill cheaper today at the cost of your sick-leave benefit and your pension tomorrow.

How to estimate your net earnings properly

The band you contribute under depends on your expected net earnings, and that is the first place many people go wrong. Net earnings are not your turnover: they are income minus deductible business expenses, and an additional deduction for hard-to-justify expenses is then applied. Invoicing €30,000 does not mean contributing on €30,000, and confusing the two leads to choosing a higher band than necessary and overpaying for months.

If your activity is seasonal or irregular, the sensible approach is to start from a prudent estimate and adjust it during the year, which the system allows several times. The later reconciliation corrects the differences, but in the meantime it is your cash flow that absorbs the mismatch.

The contribution is not the only cost

• •The monthly social security contribution, which is no longer the same for everyone.
• •Quarterly income tax instalments if you must file them.
• •The VAT you collect, which is not yours: set it aside as soon as it arrives.
• •Accountancy fees, unless you keep the books yourself.
• •Liability or health insurance, depending on the activity.

A practice that prevents nasty surprises is moving the VAT and an estimate of income tax into a separate account as soon as an invoice is paid. What remains is what you can actually spend. Many cash-flow problems among new self-employed workers come from treating money that belonged to the tax agency as their own income.

Registering, deregistering and holding two jobs

Registering and deregistering several times a year is possible and, since the reform, registrations and deregistrations are counted by actual days up to a limited number of times per year, which benefits people with intermittent activity. If you also work as an employee, you are in pluriactivity: you contribute under both regimes and may be entitled to a refund of excess common-contingency contributions, which must be requested and does not always arrive automatically. Check it every year, because these amounts are lost if not claimed in time.
