To be clear, you wouldn&#x27;t actually <i>pay</i> double-taxes (I think -- if you make more than $100k, it depends on if the Germans and Americans have a treaty over it, but most countries do, I think). You&#x27;d have to file twice, but the US side would consist of forms that say you don&#x27;t owe the US government anything because you already paid more to the Germans than the US would have charged.
