How it is calculated.
Your net earnings.
Income without VAT minus deductible expenses, leaving out the cuota itself. Yearly figures are divided by 12.
Generic expenses.
A further 7% comes off (3% for a company’s partner or director, whose base never goes below €1,424.40). What is left is the computable income the table reads.
Your band and base.
Each of the 15 bands sets a lowest and a highest contribution base. You may contribute on any base within your band.
The 31.50% rate.
The cuota is the base times 31.50%: common and professional contingencies, cessation of activity, training and the MEI equity mechanism.
The yearly adjustment.
Once the tax office has your income for the year, Social Security compares and refunds or claims the difference.

What people ask us most.
Start from your business’s net earnings, take off 7% for generic expenses (3% for a company’s partner or director) and find the band for the monthly figure. The cuota is the base you choose within that band times 31.50%.
€205.88 a month, in the lowest band, for net earnings up to €670 a month. With the flat rate, someone registering for the first time pays €80 a month for 12 months.
Anyone registering as self-employed for the first time, or who has not been registered in the previous two years (three, if they had the flat rate before). It lasts 12 months and is extended another 12 if your net earnings for the year stay below the minimum wage, €17,094 in 2026. The law set €80 for 2023–2025 and leaves the 2026 amount to a state budget that has not been passed, so €80 is still charged.
Yes, up to six times a year through Import@ss, Social Security’s online portal. Each change applies from the first day of the next two-month period: 1 March, 1 May, 1 July, 1 September, 1 November or 1 January.
The following year Social Security adjusts using your income tax data. If you paid too little, it claims the difference; if you paid too much, it refunds it.
