I am in the process of moving to Spain and trying to understand tax law with this so that when I'm using TurboTax, I don't make a mistake.
Under the new Digital Nomad Visa, you get a resident Visa, but are taxed as a non-resident. Because of this, Spain doesn't issue a Certificate of Residency, which they say is required for double taxation treaty. I haven't seen this requirement in any of the US law for the Foreign Tax Credit or the Foreign Income Exclusion. Does anyone know if you are taxed as a non-resident in Spain if you can still claim the Foreign Tax Credit for the taxes you pay to Spain?
