In terms of Premium Bond winnings (aren't we the lucky ones!) i simply enter it and treat it as interest income and enter it on a 1099-INT form - no tax withheld and payee as NS&I - seems to have worked for me in the past and has the same tax effect - much the same way as if I had an ISA with interest (which I don't!).
Thanks for that. I had thought about treating any Premium Bond wins as normal interest. Then I thought, 'well it's really a prize and not interest income'. Obviously it all works out the same and the easiest option.
I do have a savings account also with NS&I, so would I combine both amounts, (Premium Bond wins and interest income) as one payer on Schedule B?
Although it's only 'a few quid', (no champagne!), this year theres is a line for prizes, (schedule 1 line 8h) whereas past years it had to be free formatted on the miscellaneous income line, supporting details for schedule 1.
I'd be interested to learn how others have handled Premium Bond wins too.
