How does the German pension system work for expats?

The German statutory pension is a pay-as-you-go system: today's contributions fund today's pensioners, and the contributions you make today are tracked so they translate into a future monthly pension when you retire. For employees, this all happens automatically — your share comes off your gross salary on each payslip, your employer adds roughly the same amount, and the Deutsche Rentenversicherung keeps the books in the background.

After a few years of contributions, you'll start receiving an annual statement called the Renteninformation, which shows where you stand and what your projected pension at standard retirement age would look like if you kept earning at your current level.

For expats, three additional layers matter. First, EU rules coordinate pension entitlements across EU/EEA member states (and Switzerland), so contribution years in different EU countries can be added together for eligibility purposes. Second, special rules allow some non-EU citizens to apply for a refund of their own contributions after a waiting period, provided they haven't been making further contributions. Third — and this is the part most people underestimate — the projected statutory pension alone is rarely enough to maintain the lifestyle of a previously well-paid expat. Private retirement planning typically needs to fill the gap.

The statutory pension is a foundation, not a complete plan. Think of it as the floor under everything else you build for retirement, not as the whole house.
