Questions

I am a U.S. citizen living abroad — do I still pay U.S. tax?

Yes, the United States taxes its citizens on worldwide income wherever they live, and tax treaties keep that right through the «saving clause». You still file a U.S. return; double taxation is usually relieved through the foreign tax credit or the foreign earned income exclusion.

What is tax residence?

It is the status that lets a country tax all of your income, including income from abroad. For non-citizens the U.S. uses the green card test and the substantial presence test; other countries look at your home, the center of your life and the days you spend there.

Is this legal or tax advice?

No. It is an information service that shows how the rules apply to your answers. Tax authorities and courts may assess your circumstances differently, so for important decisions consult a qualified adviser.
