Can I change my Social Security contribution base if my income changes?

Last updated: July 24, 2026

Yes. Under the income-based Social Security system (in place since 2023), you can request a contribution base change up to 6 times per year.

Purchase the 'Change of Contribution Base in Social Security' add-on in the Additional Services section of your Xolo profile, and your accountant handles the request with Social Security (TGSS). Choose a base that reflects your expected net monthly income.
