Are my US 401(k) or other US retirement accounts taxed in Germany?

Many US expats in Germany want to know one thing. How does Germany treat US retirement accounts like 401(k)s, traditional IRAs, and similar plans? Germany taxes the worldwide income of German tax residents. But the US–Germany tax treaty gives special treatment to certain US tax-favored retirement plans.

Tax-advantaged schemes under the treaty

Germany often treats some US retirement plans as tax-advantaged schemes under the tax treaty. Your plan may sit on the treaty's list of qualifying pension or retirement schemes. If so, dividends, interest, and capital gains that stay inside the plan may avoid German tax for now. This holds true while the money stays in the account.

This matters a lot for long-term savers. It means the German tax office may not tax the yearly growth inside a recognized US retirement plan. That happens even though Germany would normally tax foreign investment income.

Not every US plan qualifies

Not every US account with a US tax benefit gets the same treatment in Germany. The treaty uses a defined list and set criteria. So these details matter:

• The exact type of plan you hold (for example, employer 401(k), 403(b), certain IRAs)
• Whether the plan meets the treaty's conditions for a qualifying pension or retirement scheme
• Whether the contributions and benefits look truly retirement-focused from a German view

A plan that does not qualify as a tax-advantaged scheme gets different treatment. Germany may treat the account like an ordinary investment account. That means it could tax dividends, interest, and capital gains each year, even if you take no money out.[1]

Why plan-specific advice is essential

The rules run deep, and the treaty points to set types of schemes. So the answer for a US 401(k) can differ from the answer for a Roth IRA, a SEP-IRA, or another employer plan. Germany's treatment of future payouts (when you actually take money out) can also differ from its treatment of the yearly growth inside the account.

For that reason, US expats in Germany usually need a German tax advisor to:

• Pin down exactly which US plan(s) they hold
• Check whether the plan counts as a tax-advantaged scheme under the treaty
• Confirm whether dividends, interest, and capital gains inside the plan skip current German tax
• Explain how payouts will be taxed when you take them later[1]

Practical takeaway for US expats in Germany

You hold US retirement accounts and live in Germany as a German tax resident. Do not assume all your US plans get the same shelter from German tax that they get from US tax. The safest move is simple. Have a German tax professional check your 401(k), IRA, and other US plans against the treaty rules. Then you will know which accounts are protected and which may create taxable income each year in Germany.
