It depends. What is your legal state (or country) of residence?
Unless you established legal residency in GE, then you are still a legal resident of a U.S. state; if that state was NY, all your income is subject to NY (and U.S.) tax.
"Living in Germany" does not mean you are a legal resident of Germany, unless you have met Germany's requirements to establish resident (the GE equivalent of a U.S green card).
What makes you a resident of a state (or country)?
Generally, you're a resident of a state (or country) if you intend to either stay there permanently, or return there after a temporary absence. It's where home is – where you come back to after being away on vacation, business trip, overseas or out-of-state employment, or school. Many factors are considered, not the least of which are where you are registered to vote, own homestead property and are licensed to drive.
