NO

As of 13 August 2026, AI cannot run your small business payroll.

This still needs a person who signs their name to it.

What the alternative costsThe supplied tool data lists commercial software candidates but gives no price for a compliant payroll service.

If this goes wrong, employees may be paid incorrectly and the business may submit inaccurate payroll information or miss a required payment.

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 your current GOV.UK employer PAYE and payroll guidance, and note the relevant tax year, pay frequency, pay date and whether the business operates a workplace pension.
    2. Gather the payroll records for each employee, including pay, hours or salary, tax code, National Insurance category, starter or leaver status, pension status, student loan details, benefits and statutory payments.
    3. Remove unnecessary personal identifiers, then paste the redacted records and the relevant official guidance into a chatbot with the supplied payroll preparation prompt.
    4. Ask the chatbot to produce the draft payroll table, show its sources and formulas, and list every missing or uncertain input as NEEDS CHECKING.
    5. Enter the confirmed records into compliant UK payroll software or send the draft and source records to an accountant or payroll specialist, then compare the software output with the draft for gross pay, deductions, employer costs and net pay.
    6. Check payslips, pension instructions, payment amounts and the RTI submission details in the payroll system, correct discrepancies with the payroll specialist, and submit only after the responsible employer or professional has approved the run.

    Prompt

    I need to prepare a UK small-business payroll run, but do not submit anything or present the result as final. Use only the information I provide and official GOV.UK guidance that I paste into the chat. Do not invent tax rates, thresholds, codes, dates, employee details or pension rules. First list every missing input and explain why it is needed. Then create a clearly labelled draft payroll table for the pay period [pay period], pay date [pay date] and tax year [tax year], covering these employees: [paste redacted employee payroll data]. Include gross pay, taxable pay, PAYE, employee National Insurance, employer National Insurance, pension deductions and employer pension contributions only where the supplied data supports them. Flag student loans, benefits, statutory pay, leavers, starters and irregular payments separately. Show the formula or source for every figure, identify anything that needs checking in payroll software, and produce a reconciliation checklist for gross pay, deductions, net pay, employer costs, pension handling, payslips, payment files, records and RTI. If a figure cannot be established from the supplied information and pasted official guidance, write NEEDS CHECKING instead of estimating. End with a short handoff note for an accountant or payroll specialist. This is a draft working paper, not professional advice.

    Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

What it gets wrong

  • AI cannot access your live HMRC PAYE account, pension scheme or payroll records unless a properly integrated payroll system provides that access.
  • AI cannot guarantee that tax codes, National Insurance categories, statutory payments and pension treatment are current and correctly applied.
  • AI cannot take responsibility for late or inaccurate RTI submissions, incorrect employee payments or follow-up questions from HMRC.
  • AI cannot replace the payroll software or professional check needed to validate the calculations before payment and submission.

What makes this a NO: legal accountability, verification cost and stakes of error.

FAQ

Can ChatGPT run my payroll?
No. It can prepare a draft calculation and checklist, but it cannot safely replace compliant UK payroll software or the person responsible for checking and submitting the payroll.
Can AI calculate PAYE and National Insurance?
It can perform a draft calculation when you provide complete, accurate inputs and the applicable official guidance. The result still needs checking in payroll software or by an accountant or payroll specialist before you pay staff or submit RTI.
Is AI payroll software safe for a small business?
It can reduce routine data entry and calculations, but safety depends on current rules, correct records, secure handling of employee data and a proper approval process. This is not professional advice, and a serious or unusual case needs an accountant or payroll specialist.
What can AI do for my small business payroll?
It can organise inputs, draft a payroll worksheet, explain formulas, identify missing records and create a reconciliation checklist. You still need compliant payroll software or a payroll specialist to validate the run, produce payslips and handle the employer's HMRC and pension responsibilities.
