Social security contributions

Social security contributions (OECD Classification of Taxes heading 2000) covers all compulsory payments that confer an entitlement to receive a (contingent) future social benefit. These include a) employers' social security contributions, e.g. unemployment insurance and old-age insurance premia paid by employers, b) employees' social security contributions, e.g. unemployment insurance and old-age insurance premia paid by employees, employees' contributions to the National Pension Insurance scheme and to the National Health Insurance scheme, c) social security contributions paid by independent entrepreneurs and non-employed persons, e.g. old-age insurance premia paid by entrepreneurs.

The OECD Classification of Taxes heading "Social security contributions" covers only statutory social security contributions, and does not include voluntary social security (a sub-heading under D.611 "Actual social contributions" in the national accounts).
