Before you issue it — who this form is for, and who it isn't
R185(Trust Income) looks like a small form, but three things determine whether it's even the right one to reach for.
Trustees, not personal representatives
This form is for the trustees of an ongoing trust — a trust that is still running, not an estate still being administered.
A lay trustee is very often the same person who was an executor of the estate that created the trust — a life-interest trust for a surviving spouse set up by the will is a common example — but once administration ends and assets move into the trust, they're acting in a different capacity, and the estate's own R185 (Estate Income) is no longer the right form.
The form is permissive, not mandatory
HMRC's own wording says 'Trustees may use this form' — no statute requires trustees to issue exactly this document. What is required is that the beneficiary has the figures they need for their own return; this form is simply HMRC's standard way of giving them that.
