Spain self-employed net income calculator 2026
The calculator estimates the net take-home for a Spanish autónomo (self-employed) in 2026: it subtracts IRPF-deductible business expenses, the RETA (Régimen Especial de Trabajadores Autónomos) social security quota determined by net-income tramo under Orden PJC/297/2026, and state and regional IRPF income tax applying the Art. 32.2 LIRPF reduction. Because RETA contributions are themselves deductible, the taxable base and quota are resolved iteratively. Estimate only; verify with a tax adviser.

How this is calculated
- Calculate gross IRPF net income (rendimiento neto del IRPF): subtract IRPF-deductible business expenses from total annual revenue. Under estimación directa simplificada (simplified direct-estimation method), also deduct 5% for hard-to-evidence expenses, capped at €2,000 per year.
- Derive the RETA net income for tramo lookup: apply the 7% generic deduction (estimación directa) or 3% (estimación objetiva — modules method), then divide by 12 to obtain the monthly net figure used to identify the applicable RETA tramo.
- Locate the RETA tramo under Orden PJC/297/2026: three tramos cover the reduced table (monthly net below €1,166.70) and twelve tramos cover the general table (from €1,166.70 upward). Each tramo sets a minimum and maximum contribution base; the default is the tramo minimum.
- Compute the monthly RETA quota: chosen contribution base × 31.50% total rate (contingencias comunes 28.30%, AT/EP 1.30%, MEI 0.90%, cese de actividad 0.90%, FP 0.10%). Annual RETA quota equals the monthly quota multiplied by 12.
- Resolve the circularity: RETA contributions are themselves deductible for IRPF, which reduces the taxable base and may shift the tramo. The calculator iterates to convergence — typically fewer than ten steps — ensuring the final quota and taxable income are mutually consistent.
- Apply IRPF and calculate net income: apply the Art. 32.2 work-income reduction, personal and family minimum, and state and regional IRPF scales to the converged taxable base. Final net income equals gross revenue minus deductible expenses minus RETA quota minus IRPF.
FAQ
How does the income-linked RETA system work in 2026?
Since 1 January 2023 (Real Decreto-ley 13/2022), autónomos contribute to Social Security based on actual estimated net income rather than a freely chosen base. Monthly net income determines the applicable tramo and the total contribution rate on the chosen base is 31.50% in 2026. Contributions during the year are provisional; the TGSS reconciles them against the final net income declared in the annual IRPF return.
Can I choose my contribution base within my tramo?
Yes. Within the minimum and maximum base of the applicable tramo, you may change your contribution base up to six times per year. After the fiscal year closes, the TGSS compares provisional payments against the base corresponding to your actual declared net income and issues a refund or a supplementary charge accordingly.
What is the annual RETA regularisation?
Once the annual IRPF return is filed, the TGSS recalculates contributions using the actual net income reported. If declared income exceeds the provisional estimate, the shortfall is due; if it is lower, the excess is refunded. Keeping accurate records of income and deductible expenses throughout the year supports accurate provisional contributions.
Which expenses are deductible for IRPF as a self-employed person?
Ordinary deductible expenses include supplies, office rent, insurance, depreciation, and employee wages — any expense incurred in the course of the activity. RETA contributions are also deductible, which creates the circularity the calculator resolves iteratively. Under estimación directa simplificada an additional 5% lump-sum deduction for hard-to-evidence expenses applies, capped at €2,000 per year.
Is the flat-rate tarifa plana available to new autónomos in 2026?
The regime introduced by Real Decreto-ley 13/2022 set a flat monthly quota of €80 for the first 12 months following registration. The specific 2026 amount had not been officially confirmed at the time the underlying data were verified; check the TGSS electronic headquarters for the current figure before registering.
