All I have been able to obtain is information about residents and federal employees.

Need help with. Form 1116 as far as it being needed.

U.S. Based company issued a W-2. No information for Puerto Rico was on it. ON Last paycheck stub, there is Puerto Rico tax that was withheld.

Looking at SCH 3 Non-refundable credits. Also states "Attach form 1116 if required"

Upon reading multiple IRS Articles and scenarios. Still not clear on if this form needs to be attached or not.
