Autónomo Contribution Calculator 2026 (Spain)
Calculate your autónomo Social Security quota in Spain for 2026 by real net income: bracket, minimum and maximum base and the monthly quota.
Quota = 31.50% of the base you choose within your bracket. Not included: the flat rate for new autónomos and other reductions.
What it does
Since 2023 autónomos in Spain contribute according to their real net income: income minus deductible expenses, minus 7% of generic expenses (3% for corporate autónomos), divided by 12. That monthly figure places you in a bracket of the reduced or general table, and you choose a base between its minimum and maximum. In 2026 the quota is 31.50% of the base, and the Social Security adjusts it the following year with your tax return.
How to use it
- Type your expected annual income and deductible expenses.
- Tick it if you are a corporate autónomo.
- Read your bracket, the bases and the monthly quota.
The arithmetic runs in your browser. Nothing you type is sent anywhere and nothing is stored, so you can use these with real numbers.
