What is the U.S. tax treatment for residents of Puerto Rico?

In general, you are a U.S. citizen and U.S. taxpayer if you were born in the United States. Unlike many jurisdictions, the U.S. taxes its citizens regardless of where they live (or even if they have never lived in the United States).

If you are a Non-US person or entity that receives a Form 1042-S, the tax report will be reported in USD regardless of the Base Currency you have selected for your account…

Form 480.6A is one of a series of Annual Informative Returns issued to residents of Puerto Rico. This form reports income which is not subject to withholding. As IBKR does not engage in trade or business within Puerto Rico, we do not issue the form and instead issue the U.S. Form 1099.
