Just doing some forward planning on how to report U.K Carers Allowance. From what I can see i'd report the income on schedule 1 line 8 and then add a note like, 'U.K. Carers Allowance' on the supporting details form for schedule 1 line 8. I understand that any amount is taxable in both countries though, so I can add to passive income on 1116. Line 8 of schedule 1 would then transfer to line 7a of 1040. I'd be interested what others may do, thanks.
