Do my US Social Security credits count if I move back to Europe?
Short answer: Yes, your US Social Security credits count toward your European pension eligibility through 'Totalization Agreements.' If you have at least 6 US credits but fewer than the 40 required for a US pension, the US can count your European work years to help you qualify. Conversely, Europe can count US years to meet their minimums.

Why it works this way
Totalization agreements (with France, Germany, Finland, etc.) prevent double social security taxation and close coverage gaps. Without these agreements, a worker who split a career between the US and Europe might end up with no pension from either because they never stayed in one place long enough to 'vest'.
If you have 40 credits (10 years of work) in the US, you are entitled to a US Social Security benefit regardless of where you live. However, if you have fewer (say, 24 credits), the US will look at your German or French work history to see if you have enough total years to qualify for a 'pro-rata' US benefit.
The old Windfall Elimination Provision (WEP), which could reduce your US benefit if you also drew a European pension, was repealed by the Social Security Fairness Act, signed in January 2025, for benefits payable after December 2023. Your European pension no longer cuts your US benefit. If you qualify through totalization, the US benefit is calculated pro rata.
The expensive mistake: Applying for benefits in each country separately without mentioning the other
When you reach retirement age, you should apply for your pension in the country where you live. That agency is responsible for coordinating with the Social Security Administration (SSA) in the US to calculate your totalized benefit. If you don't declare your US work years, you may be denied a European pension for 'lack of years'.
What to do
- Keep your US Social Security Number (SSN) safe — You will need this number decades from now to claim your benefits. Ensure it is recorded in your permanent records.
- Track your 'Quarters of Coverage' annually — Check your SSA.gov account before you leave to see exactly how many credits you have earned. 40 is the magic number for a full (non-totalized) benefit.
- Notify the SSA when you move — While not strictly required for credit counting, keeping your address updated ensures you receive important notices regarding your future eligibility.
