All persons living or working in Switzerland must pay OASI contributions from 1 January following their 20th birthday until retirement age (64 for women and 65 for men).
This obligation begins at age 17 if you are already working and continues after retirement age if you remain gainfully employed.
The old-age pension you receive on retirement will depend on the amount of OASI contributions you have paid during your lifetime.
If you are not working
If you are a student; if you take early retirement; if you receive a disability insurance pension or daily allowances for illness or accident; or if you are unemployed, but your entitlement to benefits has ended you must pay a minimum OASI contribution of CHF 503 per year. In addition to the OASI contributions, other mandatory contributions for disability insurance and compensation for loss of earnings are also included in this amount.
Please note: if you are not working, but your spouse or partner (in the case of a registered partnership) is working and pays at least twice the minimum annual contribution (CHF 503 x 2 = CHF 1,006), you are not required to pay anything.
If you are an employee
Half of your OASI contributions (8.7% of your salary) are paid by you and the other half by your employer. Your employer takes care of deducting the OASI contributions from your gross salary and pays them to the compensation fund.
Please note that you and your employer must pay the other mandatory contributions for disability insurance, loss of earnings compensation and unemployment insurance in addition to the OASI contributions.
If you are self-employed
You need to calculate and pay your OASI contributions (generally 8.1% of what you earn). Contact your local OASI office for more information.
Please note that you must pay the other mandatory contributions for disability insurance, loss of earnings compensation and unemployment insurance in addition to the OASI contributions.
If you postpone retirement
If you continue working after retirement age , you must continue to pay OASI contributions.
On the other hand, you will no longer have to pay unemployment insurance, as you are not entitled to unemployment benefits after reaching the statutory retirement age.
The contributions you pay during this period are calculated based on the part of your income that exceeds CHF 1,400 per month or CHF 16,800 per year).
If you work for two or more employers, this amount is deducted from your pay at every job.
Liable for contributions
If you move abroad
If you move abroad, you generally no longer pay OASI contributions in Switzerland.
In some cases (e.g. if you move abroad only temporarily or if you work abroad for a Swiss employer), you may pay voluntary OASI contributions (e.g. from a country outside of the EU/EFTA).
OASI contributions are mandatory in Switzerland. However, there may be gaps in your contributions, if for some reason you did not pay them regularly.
This might be the case for people who regularly work for different employers on short-term (maximum three-month) contracts, those who have lived abroad for many years, or those who did not pay their OASI contributions during their studies.
Failure to regularly pay OASI contributions will reduce your OASI pension. For example, one year of unpaid OASI contributions will reduce your pension by about 2.3%.
You can buy back missing contributions, but only from five years prior. It is not possible to pay for older gaps.
Contact your local OASI office for more information on buying back missing contributions.
