Tell us the tax year and period, which figure is wrong and what it should be. Do not send the payslip — we cannot accept it and do not want it. A description of the layout is more useful than the numbers.

Say which line and which year. Include what the app expected and what your payslip says — both appear side by side in the reconciliation.

Send the licence id shown in the app, never the key itself. The id is enough to look it up.

You can cancel from inside the app at any time. For anything else, say what you need and when the subscription started.

Worth telling us. Northern Ireland, agency and umbrella payslips are not read yet, and knowing who is asking decides what gets built next.
