The start of 2026 in Spain brings a relevant decision for self-employed professionals (autónomos). The Spanish Government has extended the 2025 Social Security contribution rates into 2026, without applying any general increases.
This measure was approved at the Council of Ministers held in late December 2025. It is implemented through transitional Social Security regulations applicable from the beginning of 2026 and published in the Official State Gazette (BOE).
As a result, the decision prevents automatic increases in contributions that had been under discussion during the gradual implementation of the real-income contribution system for self-employed workers in Spain.
Therefore, the contribution bases and monthly quotas applicable in 2026 remain the same as those applied in 2025. The existing contribution brackets are maintained, with no material changes to the amounts.
What does the extension mean in practice?
- Stability in contributions:
In practice, self-employed workers in Spain will continue to pay contributions based on the 2025 tables. Consequently, no automatic increases will affect the basic monthly contribution cost during 2026.
- Maintenance of brackets and structure:
Likewise, both the general table and the reduced table under the Special Regime for Self-Employed Workers (RETA) remain unchanged. This includes the 15-bracket structure based on estimated net income, which determines the applicable contribution base.
- Year-end regularisation:
As in previous years, contribution bases and quotas selected during 2026 may be regularised once the actual net income for the year is known. This adjustment follows the rules of the real-income contribution system.
Why has the contribution system been extended for 2026 in Spain?
The extension forms part of a broader package of social and tax measures. Its aim is to address situations of vulnerability and ensure a degree of regulatory stability, given the lack of full consensus in negotiations on the definitive implementation of the real-income contribution system.
Therefore, the regulations approved at the end of 2025 operate as a transitional mechanism. They maintain the current contribution conditions while social dialogue continues on the final design of the system.
Practical considerations for self-employed professionals and businesses in Spain
Overall, the extension provides greater budgetary certainty for self-employed workers. In particular, it avoids increases in monthly contributions in an economic context already marked by rising costs in other areas.
However, even though contribution amounts remain unchanged, it is still advisable to review the selected contribution base. This is because the real-income contribution system remains fully in force.
In addition, it should be noted that the current model is maintained on a temporary basis. Meanwhile, the timeline for potential future adjustments continues to be defined within the framework of social dialogue.
Indicative contribution brackets applicable in Spain in 2026
Below is a simplified overview of the contribution brackets that remain in force in 2026 following the approved extension:
| Monthly net income | Approximate contribution base | Approximate monthly contribution |
| Up to 670€ | Reduced base | From approx. 230€ |
| 670€ – 900€ | Intermediate base | Around 260€ |
| 900€ – 1,300€ | Standard base | Around 290€ |
| 1,300€ – 1,700€ | Higher base | Around 320€ |
| Over 1,700€ | Progressive base | From approx. 350€ |
*The amounts shown are indicative and may vary depending on the contingencies included and the final contribution base selected.
What should be reviewed looking ahead to 2026?
Although the extension provides stability at the start of the year, 2026 remains a key year in Spain’s transition to the real-income contribution system. For this reason, it is advisable to periodically review the chosen contribution base and assess whether it remains aligned with projected annual income.
At LEIALTA, we support self-employed professionals and companies in monitoring and reviewing their employment and Social Security obligations in Spain, providing ongoing advisory services that help anticipate changes, adjust decisions and manage contributions with greater certainty throughout the year.
