How to calculate your self-employed quota

The new contribution system lets you pay based on your real income. Follow these steps:

Calculate your net income

Enter revenue and business expenses excluding RETA. We then apply the relevant generic deduction to estimate computable income.

Select the year

This calculation supports 2026 rules for 12 full months of activity.

Indicate if you're new

Enter your situation and, if known, a confirmed actual contribution. Regional grants are not applied automatically.

Check your quota

Review ordinary monthly and annual contributions. A confirmed actual payment is shown separately when entered.
