Income generated from gift

My wife and I are both UK tax residents. Last year I transferred a lump sum via bank transfer to my wife and with this gift amount she has generated some bank interest income. Should this generated income reported in her tax return, or instead, reported in mine? Thank you.

Hi BHL,

If the interest is in an account in your wifes name only then it is her who should declare it.
If it is a joint account, you both need to declare 50/50.

Thank you.
