As of 13 August 2026, AI can only partly file a late payroll report with HMRC.

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

If this goes wrong, HMRC may receive incorrect payroll information and your business remains responsible for correcting it and dealing with any resulting penalties or employee-record problems.

A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

How to actually do it

Open the GOV.UK PAYE guidance and your payroll software or HMRC PAYE service, without giving a chatbot your login details.
Gather the payroll-period report, employee payment totals, PAYE and National Insurance figures, the original due date, the reason for lateness and any HMRC messages.
Paste the gathered facts into the prompt and ask the chatbot to identify the likely report type and produce a filing checklist, keeping confidential employee details to the minimum needed.
Compare every drafted figure and field against the payroll report and the relevant GOV.UK HMRC guidance, and mark unresolved questions instead of accepting an assumption.
Sign in to the payroll software or HMRC PAYE service yourself, enter or upload the checked report, and read the final confirmation screen before submitting.
Save the HMRC acknowledgement and submitted report with the payroll records, then ask an accountant or payroll professional about the late reason, correction or penalty if anything remains unclear.

Prompt

I need to submit a late UK payroll report to HMRC. Help me prepare the filing, but do not access any account, invent any figures, or tell me that a submission has been made. First identify whether the situation calls for an FPS, EPS or another HMRC action from the facts I provide. Then list the exact information and records needed, explain which fields are uncertain, and produce a draft checklist or table for me to enter into my payroll software or HMRC PAYE service. Use only the figures and facts below. Separate confirmed facts, assumptions and questions for HMRC or a payroll professional. Do not decide that I have a reasonable excuse, do not estimate tax, National Insurance, penalties or interest, and do not give professional advice. Tell me what I must compare against my payroll records before submitting.

Business type: [limited company or other]
PAYE reference: [reference, without login details]
Payroll period: [period]
Report believed to be required: [FPS, EPS or unknown]
Original filing due date: [date]
Actual or intended filing date: [date]
Reason the report is late: [plain description]
Employees and payments affected: [details]
Payroll software or HMRC service used: [name]
Payroll records and figures: [paste relevant records]
Any HMRC messages already received: [paste message]

Use current GOV.UK HMRC guidance where available, identify the relevant page to check, and stop rather than guess if the facts are insufficient.

What it gets wrong

AI cannot authenticate to your HMRC account or take responsibility for submitting the report.
AI cannot establish from a short description whether your reason for lateness is a reasonable excuse.
AI cannot verify that every payroll field agrees with your underlying records or prior submissions.
AI cannot negotiate with HMRC or correct an account problem after a failed or inaccurate filing.
AI cannot transfer the legal and financial responsibility away from your business or authorised agent.

What caps this at PARTLY: legal accountability, verification cost and stakes of error.

FAQ

Can AI file a late payroll report with HMRC?: Partly. AI can help identify the likely report, organise your payroll figures and prepare a checklist, but you or an authorised payroll agent must access the HMRC service and submit it. This is not professional advice; a serious or disputed case needs an accountant or payroll professional.
Can ChatGPT submit a late FPS to HMRC?: No, not by itself. ChatGPT cannot sign in to your PAYE account, confirm the final figures or give HMRC a legally accountable submission, although it can help you prepare the information.
What information does HMRC need for a late payroll report?: It depends on whether the report is an FPS, EPS or another correction, as well as the payroll period and what was paid. Gather the relevant payroll records, payment dates, PAYE and National Insurance figures, the reason for lateness and any HMRC messages, then check the current GOV.UK guidance.
Can AI avoid a late filing penalty?: No. AI can help you understand what information to gather and draft questions, but it cannot decide that your circumstances qualify for a reasonable excuse or guarantee that HMRC will waive a penalty. Ask an accountant or payroll professional about a serious case.
