For more information, read "How Germany Taxes Your Roth IRA".
Germany's 2024 tax law, effective from 2025, targeted foreign retirement accounts — which sounds like the start of a horror story. Instead, it created a strange, legalistic advantage for one account type. We walk through the paradox and translate the alphabet soup into plain English so you can understand what Germany actually does with Roth IRAs when you live there as a US expat or retiree.
We start with the foundation most people miss: the US-Germany tax treaty. A 2006 protocol adds Article 18A and explicitly names Roth IRAs by pointing to Section 408A, which is rare and hugely important. That treaty recognition can shield your Roth from German taxation while it grows, but it does not automatically make your withdrawals tax-free in Germany because the treaty lacks an “exempt if exempt” clause. From there, the real story becomes German domestic law — specifically § 22 Nr. 5 EStG, and whether your withdrawal lands in its first sentence (fully taxable) or its second (growth only).
Then we get tactical: lump sum versus lifetime annuity, the Unterschiedsbetrag pro-rata formula that determines what portion counts as taxable growth, and the half-taxation rule that can dramatically reduce what gets taxed if you meet strict timing and documentation requirements. We also bust the dangerous myth that these payouts are subject to Germany’s 25% capital gains rate. German courts treat US retirement distributions as pension income taxed at your progressive income tax rate, and your final bill may also involve the solidarity surcharge and church tax. Finally, we flag the 2025 inheritance trap in which income and inheritance taxes can stack for German-resident heirs, and we close with the most practical safeguard of all: preserving your Form 5498 paper trail.
At the link above we also dig into the surprisingly high-stakes details, like how the phrase “in consideration of past employment” can make or break your classification. One caveat: a 2026 German commentary reads the Protocol differently. Our understanding is that it's about contribution deductibility rather than the definition, but confirm with a German adviser if your position depends on it.

This is not tax advice, and German taxation of US retirement accounts moved twice between 2024 and 2026. Before acting, speak to a cross-border tax professional who is familiar with both systems.
