Albert Cabedo

We remind you that until October 31st you can request the change of your self-employed contribution base, effective from November 1, 2025. This decision allows you to adjust the fee to your actual income, optimize coverage (sick leave, maternity/paternity, cessation of activity, retirement) and avoid unwanted regularizations.

Contaldia recommendation

Already in October, you have are liable estimate of your actual income 2025.It is a good time to:

  • Increase base if you expect high income and want better coverage/retirement..
  • Decrease base if your earnings have been lower and want to avoid additional payments in the regularization.
