As of 13 August 2026, AI cannot automate your UK payroll.
This still needs a person who signs their name to it.

A wrong payroll run can underpay staff and create incorrect HMRC reporting that needs correction.

The route this page recommends
Someone with a licence or accountable authority has to sign this before it counts.

Second choiceDo it yourself
The distant thirdA chat interface gets you a draft, but you cannot verify it yourself. That is the catch.
How to actually do it
- Open the current payroll and PAYE guidance on GOV.UK, then gather the pay period, employee payroll IDs, tax codes, National Insurance categories, salaries or hourly rates, hours, bonuses, absences, statutory payments, pension settings and any starter or leaver information.
- Remove unnecessary personal identifiers and paste the anonymised records, together with the relevant current HMRC figures copied from GOV.UK, into the prompt.
- Ask the chatbot to produce the draft employee-by-employee worksheet, with every missing or uncertain item marked CHECK and no invented values.
- Put the worksheet into a spreadsheet and use Formula Bot to turn the stated formulas into spreadsheet formulas, then compare the resulting totals with the chatbot's calculations.
- Compare each employee's pay, deductions, pension treatment and payslip fields against the source records, and compare the tax and National Insurance treatment with current GOV.UK guidance.
- Send the draft worksheet and source records to your payroll accountant or payroll bureau, have them approve the calculations and submit the FPS or EPS through compliant payroll software before paying staff.
Prompt
Help me prepare, but do not file or approve, a UK PAYE payroll for [pay period]. Treat this as a draft for a payroll professional to check. I will provide anonymised employee records, pay details and deductions below. Create a clear employee-by-employee worksheet covering gross pay, taxable pay, PAYE tax, employee and employer National Insurance, pension deductions, net pay, payslip fields and the information needed for RTI reporting. Do not invent tax rates, thresholds, codes, pension settings or employee details. If a value is missing, ambiguous or depends on current HMRC rules, mark it as CHECK rather than estimating it. Separate arithmetic from rule-based decisions, show each formula, identify starter and leaver cases, and list the exact checks a payroll professional must complete before payment or submission. State that the figures are not professional advice and must be checked against current GOV.UK and HMRC guidance.

What it gets wrong
- AI cannot take legal responsibility for PAYE, National Insurance, pension deductions or RTI submissions.
- It cannot reliably resolve unusual cases such as statutory payments, benefits, corrections, attachment orders or conflicting employee records without expert judgement.
- It cannot confirm that tax codes, thresholds and payroll rules are current unless you provide and verify the relevant HMRC information.
- It cannot replace compliant payroll software that records payroll history, produces official submissions and handles corrections.
- This is not professional advice; a serious or unusual payroll case needs a payroll accountant or payroll bureau.
What makes this a NO: legal accountability, verification cost and stakes of error.

FAQ
- Can ChatGPT run my UK payroll?
- No. It can prepare a draft worksheet and explain calculations, but it cannot take responsibility for paying staff or submitting accurate RTI reports to HMRC. A payroll accountant or payroll bureau should check and run the final payroll.
- Can AI calculate PAYE and National Insurance for my employees?
- It can calculate a draft when you provide complete, current inputs, but the result still needs checking against current HMRC rules and each employee's circumstances. This is not professional advice.
- Can AI submit my payroll to HMRC?
- A general AI tool cannot act as your accountable payroll service or replace compliant payroll software for an FPS or EPS submission. Have a payroll professional approve the figures and submit them through the appropriate software.
- What can AI safely do with my payroll?
- It can organise anonymised payroll data, build a calculation worksheet, identify missing information and show arithmetic for a professional to check. Do not use its output as the final authority for payment or HMRC reporting.
