Hi
Depending on the type of trust, a tax return may be required.
Please have a look at the guidance at (
Trusts and taxes) which will help to determine if a tax return is required or a repayment claim using form R40.
You will need the infomation provided on the R185 by the trust, if you are completing a R40 or Sa107 (trusts) page for self assessment.
Thankyou.
