How we estimate the quotas for 2026-2031

In 2022, the Spanish government set in motion a scheme to gradually increase the social security payments for self-employed over a transitional period of 9 years from 2023 to 2031. For now, the government has only published the new quotas for the years 2023-2025, while the values for the following years will not be known until 2025. Nevertheless, our calculator allows you to use fiscal years up until 2031, the last year of the transition period. Below we explain how this was achieved.

Before the current scheme was approved, the government already indicated how they would like to increase the contributions until 2031 and the proposed scheme was published in an article in el País. While this scheme has since been replaced, it nonetheless provides an indication of where the government would like to be by the end of the transition period in 2031. So, to estimate the contributions for the years from 2026-2031, we used the quotas for the years already known (2023-2025), added the endpoints (2031) from the scheme in the el País article, and applied a least squares regression (best fit) of a second order polynomial to obtain the intermediate years 2026-2030. The result is shown below.

Clearly, these are highly speculative at this point and are only meant to provide an indication of where things might be headed after 2025...

Points to note:
  • Results are indicative only. There are deductions and special cases that have not been taken into account.
  • *This refers to the difference between your total billed amount less your expenses but without deducting the social security fee. For example, if you invoiced your clients for €60,000, had expenses of €20,000, and paid €5,000 to social security, then your net revenue is €40,000 (do not deduct the SS fees to obtain the net revenue as this is deducted later to arrive at the taxable income).
  • ** Important: For years 2026-2031 the social security contributions are estimates (see here).
  • §A deduction of 7% has been applied for general expenses (gastos genéricos - no receipts required) based on the type of autónomo. This replaces the deduction of 5% for gastos difícil justificación from the old system. A limit of €2000 p.a. has been applied to both although we still do not know whether the same limit applies or whether this will increase as well. The difference between net revenues and these general expenses is the income that will be used to calculate your social security quota.
  • #This is the minimum social security contribution you will have to pay. You can always choose to pay more. Important: For years 2026-2031 the social security contributions are estimates (see here).
  • You are on a fixed (reduced) social security quota since you only started your activity recently.
  • you can earn up to €1,120 more per year before you move to the next highest social security bracket which would result in a monthly quota of €350.
  • if you earn €4,040 less per year you will move to the next lowest social security bracket with a monthly quota of €320.
