Discounted Gift Trust

I receive a small monthly payment from a Discounted discretionary gift trust, which I was informed was not liable for payment of tax from me. The payment totals £4000 a year. I am now trying to complete my 2022-23 tax return and wondered where and how I enter this if I need to. Any advice would be most helpful.

Hi Alison Williamson,
Take the figure from box 1 on the R185 you will have received from the trust and put this on the trust page SA107 at box 1.
Thank you.
