AHV
Old Age Insurance (AVS)
[Ah-Ha-Fow]Simple Definition
The state pension scheme (Social Security) mandatory for all residents. It provides a basic subsistence level of income in retirement.
Why this matters to Expats.
The "Solidarity Pillar". High earners pay heavily into it but the payout is capped (Max pension: ~CHF 2,450/month). It is a "Pay-as-you-go" system, not a savings account.
Actionable Intelligence
Contribution Gap (Beitragslücke): If you don't work (e.g., student, housewife) but live here, you MUST pay the minimum (~CHF 514/year) as a "Non-Employed Person" (Nichterwerbstätige). If you miss years, your pension is permanently cut.
OASI Number: Your 13-digit social security number (756.xxxx...) is your lifetime ID for everything in Switzerland.
Frequently Asked Questions
Can I cash it out?
Generally NO. Even if you leave Switzerland (to EU/EFTA). You only get it at retirement age (65).
What if I go to the US?
For non-EU countries, you might be able to refund contributions, but you lose the future pension rights. Check the specific social security treaty.
