Germany doesn’t have a 401k, but many employers offer a Betriebliche Altersvorsorge (bAV): an occupational pension via salary sacrifice or employer contributions. US citizens can usually join, but the US tax treatment often differs from Germany’s.

Property, Not Funds

Are you a US citizen living in Germany?

Real estate can reduce your taxes and build wealth for you, without all the US citizen restrictions. PFIC, PRIIPs, and broker limits are fund problems -- a property you own directly sits outside them.

Quick Answer

  • Yes, you can participate in your employer’s bAV in Germany.
  • Contributions reduce taxable income in Germany, but the US may tax contributions and growth currently (no automatic deferral like a US 401k).
  • Expect extra reporting (FBAR/FATCA; sometimes trust reporting) and coordinate both tax returns annually.

How bAV works in Germany (plain-English)

  • Funded by you (Entgeltumwandlung) and/or your employer.
  • Contributions up to statutory caps can be tax- and social-contribution-favoured in Germany.
  • Investment vehicle varies: insurance contracts, pension funds, direct commitments.

US tax overlay for US persons

  • The US may treat employer contributions as current income.
  • Investment growth inside certain German pension wrappers can be taxable annually in the US.
  • Some plans create foreign trust issues (possible Form 3520/3520-A): get plan documentation reviewed.

Practical strategy

  • If your employer matches, the German tax+match benefit can outweigh US friction: often still worth joining.
  • Keep US retirement saving in Traditional/Roth IRA only if you have US earned income and your broker allows contributions from abroad.
  • Maintain a US brokerage for PFIC-safe investing outside the bAV.

Worked example (illustrative)

  • Salary €120k; you contribute €5,000; employer adds €3,000.
  • Germany: salary reduction + employer subsidy: strong net benefit now; pension taxed later on payout.
  • US: you may include part/all contributions in current income; file any required forms; credit German tax later on payouts if taxed twice.

Common pitfalls

  • Assuming the US treats bAV like a 401k:it doesn’t.
  • Missing US forms (FBAR/FATCA/3520 where applicable).
  • Choosing high-fee insurance wrappers without understanding surrender costs.

Next steps

  1. Ask HR for the plan type and full documentation.
  2. Have a US-German tax advisor review US treatment and forms.
  3. Decide contribution level based on employer match and your cross-border plan.
  4. Track contributions and statements for both returns.
