As of 13 August 2026, AI cannot correct an error in your UK payroll.

What to actually do

1. Hand it to a person

   The route this page recommends

   Someone with a licence or accountable authority has to sign this before it counts.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface gets you a draft, but you cannot verify it yourself. That is the catch.

   How to actually do it

   1. Open the affected payroll run, payslip, payroll summary and relevant RTI submission record, then make redacted copies without names, addresses, National Insurance numbers or bank details.
   2. Gather the employee's relevant tax code, pay components, deductions, pension information, year-to-date figures and the payroll period in which the error occurred.
   3. Paste the redacted records and the exact error into the prompt, including whether the payroll has already been finalised or reported.
   4. Ask the chatbot to produce the comparison table, missing-facts list and handover note, and to separate supplied figures from calculated figures.
   5. Compare every calculated figure with the payroll software's own preview or correction calculation and check the relevant HMRC guidance on GOV.UK.
   6. Send the records, the AI draft and the comparison to your payroll manager or payroll accountant, who should decide the correction and any required FPS or EPS action.
   7. Apply the approved correction in the payroll software, generate the revised payslip and payroll reports, and have the payroll professional check them before payment or submission.

   Prompt

   You are helping me prepare, not authorise, a correction to a UK payroll error. This is not professional advice. Do not invent figures, tax codes, dates, employee details or HMRC rules, and do not tell me to submit anything without professional review.
   
   Using only the information I provide, do the following:
   1. State what appears to be wrong and list every missing fact that prevents a reliable correction.
   2. Recalculate the affected gross pay, taxable pay, PAYE, employee National Insurance, employer National Insurance and net pay only where the supplied records support the calculation. Label each figure as supplied, calculated or uncertain.
   3. Explain whether the error appears to affect the current payroll, an earlier payroll period, year-to-date figures, an employee payslip, an FPS or an EPS. Do not decide the reporting treatment where the facts are insufficient.
   4. Produce a table showing the original figure, corrected figure, difference and source for each affected item.
   5. Give a separate list of questions for the payroll manager or payroll accountant to answer before anything is changed.
   6. Give a short handover note describing the suspected error and the checks still required.
   
   Use UK payroll terminology. Keep employee information to the minimum needed and redact names, addresses, National Insurance numbers and bank details. Quote or link only to current GOV.UK guidance that you can verify, and say when a point needs confirmation from a payroll accountant.
