Tax return

Which Box on the declaration should bank interest be entered? I have been told 8TS by one source and 8TR by another. The guidance material is very unclear (to me).

8TS, at least we did it last year and did it again now and so far no 'news' to tell us it is wrong (for the tuppence we declare it seems hardly worth it).

Ours goes in Box 2GO on the declaration complimentaire which is form 2042C I usually have to download this from the internet as they stoped posting it with the others a couple of years ago and the same amount is entered on the inside page of the Pink form. On form 2042C I also enter the tax paid in the Uk including that deducted from the bank interest in box 8TH

8TK is the total from the back page of the Pink form
