Self-employed contributions in Spain 2026: progressive income-based system
The contribution model for self-employed workers in Spain underwent a structural shift on 1 January 2023: Royal Decree-Law 13/2022 abolished the long-standing flat contribution and replaced it with a progressive system based on real net income from self-employment. Four years on, the system has consolidated, brackets continue to scale, and the annual reconciliation carried out by the Spanish Social Security Treasury (TGSS) has become one of the main pain points—and sources of unpleasant surprises—for many self-employed workers. This guide explains how the current system works, what brackets exist, how net income is calculated, what reductions are available (flat rate included) and the mistakes that are costing the most money.
In summary
- Since 2023, contributions are calculated on real net income distributed across 15 brackets, with a multi-year horizon (2023-2025 and subsequent consolidation) in which minimum and maximum contributions have been progressively adjusted.
- Net income is obtained by subtracting deductible expenses from revenue and applying an additional deduction for generic expenses (7% as a general rule, 3% for incorporated self-employed workers).
- The flat rate (tarifa plana) for new self-employed workers is €80/month for 12 months, extendable for an additional 12 months if net income remains below the Spanish minimum wage (SMI).
- The TGSS performs an annual reconciliation in the following tax year: if contributions do not match the real income reported to the Spanish Tax Agency (AEAT), it refunds any excess or claims the shortfall.
- Self-employed workers must choose their bracket upon registration and may change it up to six times a year. Aligning the bracket with the real forecast is decisive to avoid unexpected reconciliations.
What are self-employed contributions and what do they cover?
Self-employed contributions are the monthly payments to Spain's Special Scheme for Self-Employed (RETA) that grant access to Social Security benefits: contributory retirement, temporary and permanent disability, cessation of activity allowance (the self-employed worker's "unemployment benefit"), maternity and paternity, healthcare and, where applicable, training and risk prevention. Unlike employees—whose contribution is calculated and paid by the employer—the self-employed worker is directly responsible for calculating, declaring and paying.
Contributing more or less affects two levels: the financial one (how much you pay each month) and the benefit one (the amount of your pension, sick leave or cessation of activity allowance). Under the old system, almost everyone contributed at the minimum base and, as a result, all benefits were also at the minimum. The progressive system has changed that logic by linking contributions to real income.
From the flat system to the progressive one: what changed in 2023
Until 31 December 2022, the self-employed worker freely chose their contribution base within minimum and maximum limits, and paid a fixed percentage (around 30%). In practice, more than 80% of self-employed workers contributed at the minimum base, which created two problems: insufficient funding for the system and very low future benefits.
Royal Decree-Law 13/2022, the result of an agreement with the main self-employed associations, introduced a system of 15 brackets based on monthly net income. Each bracket has a minimum and a maximum contribution base; the self-employed worker chooses within the band, and the TGSS performs a reconciliation the following year if real income places them in a different bracket.
Note: the change is not applied all at once. The reform foresees a multi-year transition period (2023-2025 with gradual adjustments and consolidation from 2026). The minimum and maximum contributions of each bracket rise year by year, so it is advisable to consult the current bracket table for the tax year on the Social Security e-portal before choosing a base.
Current contribution brackets (2025-2026 reference)
As an indicative reference, the 15 brackets are structured as follows. The figures are approximate and come from the official tables published by the Spanish Ministry of Inclusion and Social Security; always check the updated table for the tax year before choosing a base.
| Bracket | Monthly net income | Approximate monthly contribution |
|---|---|---|
| 1 | ≤ €670 | ~€200 |
| 2 | €670 - €900 | ~€220 |
| 3 | €900 - €1,166 | ~€260 |
| 4-7 | €1,166 - €1,700 | ~€290 - €320 |
| 8-10 | €1,700 - €2,760 | ~€330 - €380 |
| 11-13 | €2,760 - €4,720 | ~€390 - €460 |
| 14 | €4,720 - €6,000 | ~€510 |
| 15 | > €6,000 | ~€590 |
Within each bracket, the self-employed worker may choose any base between the minimum and maximum of the range. Contributing at a higher base means a higher monthly payment and, in return, better future benefits (retirement, temporary disability, cessation of activity).
How net income is calculated
The calculation has two stages. First, net income is determined according to Personal Income Tax (IRPF) rules (gross income minus tax-deductible expenses, depending on the assessment method—normal direct estimation, simplified direct estimation or objective estimation). Second, an additional deduction for hard-to-justify expenses is applied to that net income:
- 7% as a general rule for the individual self-employed worker.
- 3% for the incorporated self-employed (autónomo societario)—director or working partner of a commercial company.
The difference between 7% and 3% lies in the fact that the incorporated self-employed worker already deducts personal and professional expenses through the company, so the regulation considers that they do not need such a wide margin for hard-to-justify expenses.
Calculation example: a self-employed worker with €36,000 in annual revenue and €6,000 in deductible expenses has net income of €30,000. Applying the 7% deduction, the income for contribution purposes is €27,900 per year, or about €2,325 per month, which places them in bracket 9-10.
Flat rate: €80/month with extension if income is low
The flat rate (tarifa plana) was one of the major entrepreneurship incentives of the previous system and is maintained, although reformulated within the new system. The current reduced contribution is €80 per month for the first 12 months of registration in RETA, provided the requirements are met:
- First registration in RETA, or resumption after at least 2 years without being registered (3 years if the flat rate was previously enjoyed).
- No debts with Social Security or the Tax Agency at the outset.
- Expressly request the flat rate upon registration.
After the first 12 months, the self-employed worker may extend the reduced contribution for another 12 months (up to a total of 24 months) if their annual net income remains below the Spanish minimum wage (SMI). The extension is not automatic: it must be requested and the income forecast must be substantiated.
Other available bonuses and reductions
- Family-work balance: 100% bonus on the contribution for the care of minors or family members with disabilities, for a maximum of 12 months.
- Maternity and paternity: 100% exemption from the contribution during periods of leave for birth, adoption or foster care.
- Self-employed workers in municipalities of fewer than 5,000 inhabitants: extended flat rate to address the demographic challenge.
- People with disabilities, victims of gender-based violence or victims of terrorism: reductions of up to 80% on the contribution for 24 months.
- Collaborating family members (spouse, relatives up to the second degree): 50% bonus during the first 18 months and 25% during the following six.
- Concurrent employment (pluriactividad) (simultaneous registration in RETA and in the general scheme as an employee): partial refund of contributions if the joint cap is exceeded.
Annual reconciliation: the moment of truth
Each year, once the IRPF return has been filed, the TGSS compares the self-employed worker's real net income with the base on which they contributed. This is called annual reconciliation and can produce two effects:
- Refund: if you contributed at a higher base than the one corresponding to your real income, the TGSS refunds the excess automatically (no express request needed).
- Supplementary settlement: if you contributed at a lower base than the one corresponding to your real income, the TGSS claims the difference. This is one of the most feared effects of the new system, especially among self-employed workers whose billing grew significantly during the year and did not adjust their bracket.
Critical deadline: the self-employed worker may change their contribution base up to 6 times a year (effective on 1 February, April, June, August, October and December). Adjusting the bracket to the reality of each quarter is the best way to avoid unexpected reconciliations. Failing to update the base when income grows is one of the most costly mistakes in practice.
Practical cases
Case 1 — Freelance designer just starting out
Lucía registers as self-employed in January. She applies for the flat rate: she will pay €80/month for 12 months. In her first year she bills €14,000 with €2,000 in deductible expenses (net income €12,000, roughly equivalent to the SMI). As her net income does not exceed the SMI, she can extend the €80 contribution for another 12 months, up to the total of 24 months.
Case 2 — Consultant with stable income
Carlos, a marketing consultant, bills €60,000 a year with €12,000 in expenses. Net income: €48,000 → he applies the 7% deduction → computable income: €44,640 (about €3,720/month). He falls in bracket 13, with a contribution close to €450/month. If he chooses a higher base within the bracket, he pays a higher contribution but improves his future retirement pension.
Case 3 — Sole director of an SL with a salary
Marta manages a company in which she is the majority shareholder. She receives €36,000 gross from the company as director. Since she is an incorporated self-employed (autónoma societaria), the additional deduction is 3%, not 7%. Her computable income is approximately €34,920 per year (about €2,910/month), which places her in bracket 11-12.
Case 4 — Concurrent employment: employee and self-employed
Pablo works as an employee in a company (€30,000 salary) and, at the same time, is registered as self-employed providing programming services to other clients (€20,000 additional). He contributes to both schemes. If the sum of the bases exceeds the legal maximum cap, he can request a partial refund of RETA contributions for concurrent employment at the end of the tax year.
Common mistakes that cost money
- Not updating the contribution base when income grows: leads to reconciliations payable the following year, sometimes amounting to several thousand euros at once.
- Forgetting to request the flat rate at registration: if it is not expressly requested, the TGSS applies the ordinary contribution. Subsequent correction is complicated.
- Confusing the 7% and 3% deductions: applying the 7% deduction while being a corporate director is one of the most common errors detected during reconciliations.
- Not notifying cessation of activity: remaining registered without real activity generates debts and, where applicable, surcharges.
- Always contributing at the minimum without thinking about the future: the logic of the old system perpetuated under the new one, without assessing the impact on retirement or potential sick leave.
- Not reviewing concurrent employment: many self-employed workers with a second job as an employee fail to request the partial refund they are entitled to.
- Not deducting legitimate expenses: a vehicle used for business, premises utilities, professional training or insurance can reduce net income and, with it, the contribution.
Annual self-employed checklist
At the start of each year
- Review the net income forecast for the tax year and choose the appropriate bracket.
- Consult the updated table of bases and contributions on the Social Security e-portal.
- Confirm whether to maintain, extend or request new bonuses (work-family balance, concurrent employment, etc.).
Each quarter
- File Form 130 (direct estimation) or Form 131 (objective estimation) and, if applicable, VAT (Form 303).
- Review whether real income deviates from the forecast: if so, change the contribution base at the next available window (1 February, April, June, August, October or December).
After the IRPF return
- Wait for the TGSS's annual reconciliation notice (usually arrives between September and December of the following year).
- If the reconciliation results in a supplementary settlement, assess the deadlines and, where applicable, file objections if errors are detected in the calculation.
- Review benefit coverage (retirement, temporary disability) and consider whether to contribute at a higher base within the bracket.
Frequently asked questions
Can I change brackets during the year?
Yes. The self-employed worker may change their contribution base up to 6 times a year, effective on 1 February, April, June, August, October and December. It is the key tool to align with real income and avoid reconciliations.
Is the flat rate compatible with other bonuses?
Some are, others are not. The flat rate is incompatible with most category-based bonuses (disability, gender-based violence victim, etc.) during the period in which it applies. It is worth analysing case by case which is more advantageous.
What happens if I have several months on the flat rate and stop meeting the requirements?
The TGSS performs a reconciliation and claims the difference between the flat-rate contribution and the contribution that should have applied. For example, if you cancel your self-employed registration and re-register before the minimum waiting period, you lose your right to the flat rate for that cycle.
Is net income calculated according to IRPF or in another way?
It starts from the net income under IRPF (gross income minus deductible expenses according to the applicable assessment method), and then the additional 7% deduction (general) or 3% (incorporated self-employed) is applied. The AEAT and the TGSS automatically exchange information for the reconciliation.
Will I receive a higher pension if I contribute at a higher base?
Yes, within the legal caps. The pension calculation base is determined using the most recently contributed bases (currently those of the last 25 years, with transition periods). Contributing at a higher base also improves the temporary disability and cessation of activity benefits.
Can I deduct my vehicle or my home as a self-employed worker?
It depends on the degree of business use and on the evidence you can provide. The vehicle is only 100% deductible in specific cases (transport activities, commercial vehicles, etc.). The proportional part of home utilities (electricity, water, internet) is deductible when working from home, provided the percentage of business use has been reported and substantiated.
What happens if I have debts with Social Security?
Debts accrue surcharges (10-20% in the first months, up to 35% if enforcement proceedings begin) and block access to bonuses, certificates and, in many cases, public aid. There are deferral and instalment options that should be activated in good time.
Conclusion
The progressive system of self-employed contributions in Spain is, on paper, fairer than the previous one: those who earn more pay more and, above all, those who earn little pay less. In practice, it requires active management: review brackets at the start of the year, adjust the base when billing changes, do not miss bonus windows and understand that the TGSS's annual reconciliation is the rule, not the exception. Well managed, the system allows contributions and future benefits to be optimised; poorly managed, unexpected reconciliations can mean several thousand euros at once.
