Every self-employed worker in Spain must make monthly social security contributions. This guide explains how these fees are calculated and how they protect you.
The monthly payment is mandatory even if you do not earn any income in a given month.
Understanding the RETA system
Self-employed workers belong to a special social security regime in Spain.
This regime is called the Régimen Especial de Trabajadores Autónomos, commonly known as RETA.
The monthly payment you make to this system is called the cuota de autónomos (autónomo fee).
This fee is collected automatically by direct debit on the last working day of every month.
What do your contributions cover?
Your monthly contributions are not just a tax.
They fund a range of social benefits and insurance protections.
Public healthcare
You receive full access to the Spanish public healthcare system, called Sanidad.
This coverage includes your immediate family members if they depend on your income.

Sick leave and disability
You can claim temporary disability benefits, called incapacidad temporal, if you fall ill or have an accident.
This benefit pays a daily allowance after a specific number of sick days.
Family benefits
Contributions cover paid leave for pregnancy, birth, and childcare.
Both mothers and fathers receive 16 weeks of paid leave after a child is born.
Retirement and unemployment
Your contributions count towards your future state retirement pension.
They also fund a basic unemployment benefit for freelancers, called cese de actividad (cessation of activity).
How your fee is calculated
Spain uses a contribution system based on your net real income, called rendimientos netos.
You must estimate your income and choose a corresponding bracket.
Calculating your net real income
Your net real income is not just your gross invoicing amount.
To calculate it, take your total business income and subtract your deductible expenses.
Next, apply an automatic 7% deduction for general business expenses.
The resulting number is your net real income for social security purposes.
Example: Your monthly gross invoicing is €3,000. Your expenses are €500. Your net income before the deduction is €2,500. You subtract 7% (€175) to get a net real income of €2,325.
Contribution brackets and standard fees
The social security agency defines 15 distinct income brackets.
Each bracket has a minimum and maximum contribution base.
Your monthly fee is approximately 31.2% of your chosen contribution base.
Here are some standard monthly fees based on net monthly income:
- Income under €670.00: The minimum monthly fee is approximately €230.00.
- Income between €1,700.00 and €1,850.00: The minimum monthly fee is €320.00.
- Income over €6,000.00: The minimum monthly fee is €540.00.

Adjustments and end of year settlement
Because freelance income changes, you can adjust your bracket throughout the year.
The system performs an annual reconciliation at the end of the tax year.
Changing your bracket online
You can change your estimated income bracket up to six times a year.
You must request changes online through the social security portal, called Import@ss.
This helps you match your contributions to seasonal income fluctuations.
Annual tax reconciliation
At the end of the year, Hacienda shares your actual tax return data with the social security agency.
The agency will calculate your exact average net income for the year.
If you contributed too little, they will send a bill for the difference.
If you contributed too much, they will automatically refund the overpaid amount.
Paying your first monthly fee
The social security agency charges the fee by direct debit at the end of the month.
However, your first fee might be charged differently.
If you register late in the month, the system might not process your bank details in time.
In this case, you will receive a double charge at the end of the second month.
You should monitor your bank account to ensure the payment is successful.
Checklist of RETA benefits

Questions and answers
Can I choose to pay a higher fee for a better pension?
Yes. You can choose to contribute based on a higher base within your income bracket. This increases your future pension and sick leave payouts.
What is the flat rate fee for new freelancers?
Eighty euros per month. New freelancers can pay a reduced flat rate, called the tarifa plana, for the first year. In Madrid, you can extend this discount if you meet specific requirements.
What happens if the direct debit fails?
You will face a penalty. Social security will charge an automatic 10% surcharge if you pay in the next month. The surcharge increases to 20% if you delay further.
Are social security fees tax-deductible?
Yes. You can deduct your social security payments as business expenses on your quarterly IRPF income tax returns.
Do I pay social security if I am on sick leave?
Yes. However, from the 61st day of sick leave, the social security agency will pay your monthly fee for you.
Can I register as autónomo if I already have health insurance?
Yes. Having private health insurance does not exempt you from paying public social security fees. The public contribution is mandatory by law.
How do I prove I have paid my monthly fee?
Use your bank statements. You can also download a certificate of payment from the social security portal. Gestores often request this document.
Do I get a pension if I move away from Spain?
Yes, under bilateral agreements. Spain has social security treaties with many countries, including EU members and the United States. Your contributions can transfer or count toward your home pension.
