If you are an autónomo planning 2026, use the current Social Security tables rather than a headline monthly figure from 2025. Your provisional contribution depends on the net-income tranche and the base chosen within the permitted range, then may be regularised against your actual income.
Autónomo contributions in 2026: what actually applies
Spain’s net-income system still uses 15 tranches: three in the reduced table and twelve in the general table. The 2026 contribution order sets the permitted monthly bases for each tranche, from EUR 653.59–718.94 in the lowest reduced tranche to a maximum base of EUR 5,101.20. A base is not the same thing as the final quota, so avoid treating a simplified EUR200–EUR590 range as a current bill.
The current framework follows Real Decreto-ley 3/2026 and Orden PJC/297/2026. Check the Social Security guidance and Import@ss when choosing a base, because the amount depends on your circumstance and the current official calculation.
Your expected net income and the base you choose matter throughout the year. Keep records that support the forecast and revisit it through the official service when the business changes, rather than relying on an old table or a social-media calculator.
Frozen quotas and the MEI: how they hit your monthly bill
Your 2026 payment uses the net-income tranche and chosen contribution base. The official order sets the base ranges; the applicable rates and any special circumstances determine the resulting quota. Use the current calculator or Social Security guidance for a personal figure.
The Mecanismo de Equidad Intergeneracional (MEI) is 0.9% in 2026. It applies to the relevant contribution base; calculate it with the official quotation rules rather than adding it to an assumed flat amount.
Use Import@ss to keep the provisional choice aligned with expected income and retain invoices, expenses and the confirmation of every change. This reduces the risk of a large adjustment once actual income is assessed.
Tarifa plana and its prórroga in 2026
The reduced quota for new autónomos has its own eligibility and extension conditions. Confirm the amount, start date and any extension rule directly with Social Security before budgeting, because a general article cannot establish an individual entitlement.
For 2026, the annual minimum interprofessional wage (SMI) is EUR17,094 (EUR1,221 per month in 14 payments), under Real Decreto 126/2026. If you are considering a reduced-quota extension linked to income, verify the exact timing, evidence and threshold with Social Security; do not reuse a 2025 figure or assume an extension is automatic.
Use the Social Security electronic office and save the receipt for any request or change. If a condition is unclear, obtain confirmation from Social Security or a qualified adviser before the relevant deadline.
Adjusting your tramo and paperwork timeline
Update your forecast through Import@ss when expected income changes. It is the right place to check the current choices available for your record.
When you file each change, save the estimate you used plus invoices and expenses so regularization is painless. If you are still setting up, lean on this guide to keep paperwork tidy: how to open autonomo in Spain.
Also keep your bank details and contact email current, so you receive notices about your contributions and any later regularisation.
Action plan for expat autónomos in 2026
Map income scenarios using the official 2026 base table and leave a buffer for the final contribution calculation and any adjustment. A reliable budget starts with the correct tranche and base, not a universal monthly quote.
Set reminders for any reduced-quota deadline that applies to you and for reviewing your expected income. Check the official conditions before acting; meeting an income threshold alone does not prove entitlement.
For a decision that affects cash flow or entitlement, cross-check the official service and consider a qualified gestor. This guide is a starting point, not individual tax or Social Security advice.
Conclusion
For 2026, use the current net-income table, account for MEI at 0.9%, and verify any reduced-quota condition directly with Social Security. Keep receipts and forecasts tidy, and update the official record when your expected income changes.
