U.S. Tax Filing for Americans in Berlin

Berlin's American community clusters around its startup and tech scene, the arts, academia and freelancing (the city's many Freiberufler). Germany and the U.S. have a tax treaty and a totalization agreement, but German pension products, flat-rate investment tax and self-employment all add U.S. reporting layers.

Typical situations we see in Berlin

• Startup and tech employees with RSUs, options and bonuses to reconcile across German and U.S. rules.
• Riester and Rürup pensions and other German retirement products whose U.S. and treaty treatment can differ from the German one.
• German investment income taxed under Abgeltungsteuer (flat-rate withholding) and how it maps to the U.S. Foreign Tax Credit.
• Freelancers (Freiberufler / Selbständige) with self-employment that may trigger U.S. self-employment tax considerations and the totalization agreement.
• German funds and ETFs held locally that may be PFICs (Form 8621).

Freelancers and self-employment

If you freelance in Berlin, the U.S. self-employment tax rules and the U.S.–Germany totalization agreement can affect what you owe and where social contributions land. It is generally worth reviewing before filing. Atamatax provides preparation support; this is not individualized advice.
