With the new contribution system based on actual earnings you need to inform your incomes in order to adjust your contribution. 

Autonomos who register in 2023 will need to do so at the time of registration. However, Autonomos who were registered in 2022 will go into the new system with the same base that they had, typically the minimum contribution base of 960€. They have until October 2023 to report their actual earnings. Ideally sooner than that.

If you foresee that your net annual income, on a monthly average, is different from what you initially expected, you can adjust your contribution base up to six times per year.

The modification of the bases is not immediate, but depending on when you make the notification, the change will be effective on the first day of the following months: March, May, July, September, November 2023 and January 2024.

The aim of this provision is to make it possible for the result of your regularisation to be zero at the end of the year.
