Starting this year, under the new real income-based contribution system, the General Treasury of Social Security (TGSS) will carry out the annual adjustment of contributions for 2024.

How the process works

The adjustment compares the provisional contribution bases you chose during the year with the actual net income reported to the Tax Agency.

Possible outcomes

  • No differences: No action is required.
  • Refund due to you: TGSS will automatically return the amount owed before April 30, 2026.
  • Amount owed to TGSS: You will need to pay the amount indicated in the notice within the deadline to avoid penalties.

If you contributed on a higher base than required, you can choose to keep it to maintain higher benefits. This option must be exercised by the last day of the month following the notification.

Notifications and recommendations

Notices will be sent through the official online channels (DEHú, Import@ss). Make sure your contact and banking information is up to date to avoid delays or problems.
