Find your 2026 contribution band
Compare standard contributions with an eligible first-year tarifa plana or second-year low-income extension. See your monthly payment, 12-month total and savings.
The 2026 figures here are enacted official values, not projections. This is a band lookup for a standard individual autónomo; company-director floors, regional reimbursements, pluriactivity, special activities, chosen higher bases, and later regularization are not modeled. Reduced quotas apply only when you confirm eligibility.

How the RETA estimate works
Results are calculated in your browser. The form does not send your income to our server.
Standard contribution
The 2026 band gives a permitted contribution-base range. This tool applies the 31.5% combined rate to the standard minimum base for that band and shows a 12-month scenario.
Reduced quota
An eligible reduced month uses €88.64 including MEI. The second-year extension requires a request and annual net returns below the annual SMI. Confirm eligibility and later regularization with Seguridad Social.
