Contribution Caps
Summary
Contribution caps are statutory limits that restrict the amount of income on which social contributions are calculated. Once a defined income threshold is reached, contributions may stop increasing or may apply at a reduced rate. Contribution caps are a structural feature of many European social‑security systems, but their presence, level, and effect vary by country.
