AHV Contribution Obligation / AHV Calculation

The OASI insurance is mandatory for persons with civil domicile or gainful employment in Switzerland, as well as for certain Swiss citizens working abroad. The principle of the place of employment determines the subjection to social insurances. Contributions to OASI/DI/OE are age and status dependent. Employees and employers share the contributions. For self-employed persons, a decreasing contribution scale applies, and for non-employed persons, contributions are assessed according to assets and income. Minor wages under CHF 2,500.00 are only subject to contributions at the request of the employee, except in private households and cultural sectors. The contribution rates for 2026 are listed in a table.
