Spanish freelancer social security calculator 2026
Work out your monthly self-employed (autónomo) social security contribution for 2026 under the real-net-income system. Enter your net income to see your bracket, your contribution base and what you'll pay to Social Security.
Your estimated contribution
Estimate based on the minimum base of your bracket, which is what most freelancers pay.
This calculator gives an indicative estimate for 2026 and is not tax advice. Your actual contribution depends on the base you choose and on Social Security's annual adjustment based on your final income.
Contributions based on real income
Since 2023 you contribute according to your net income: each income bracket has a minimum and a maximum base, and you choose within that range.
Flat rate
New freelancers pay €80/month during the first year, with a possible 12-month extension if their income stays below the minimum wage.
Annual adjustment
The Social Security treasury compares your base with your real income-tax earnings and refunds or claims the difference the following year.
