HMRC carries out compliance checks to ensure employers are operating PAYE correctly. This guide explains what triggers a check, what to expect, and how to prepare.
Why HMRC might check your PAYE
- Random selection - routine checks on a sample of employers
- Risk indicators - late submissions, frequent corrections, sector patterns
- Third-party information - tips or information from other sources
- Discrepancies - differences between RTI and other returns
- New employer - first-year employers sometimes checked
- Notice period
- Usually 7-14 days written notice before visit
- Record retention required
- Minimum 3 years after end of tax year
- Penalties for non-compliance
- Up to 100% of unpaid tax, plus interest
- Appeal rights
- 30 days to appeal any penalty notice
Records HMRC may ask for
- Payroll records - employee details, pay, deductions, tax codes
- RTI submissions - FPS and EPS submissions for reviewed periods
- P45s and P60s - employee forms issued
- Starter checklists - forms completed by new employees
- Payment records - evidence of payments to HMRC
- Employment contracts - to verify employment status
- Expense claims - receipts and approval records
- Benefits records - P11D working papers
Common areas of scrutiny
- Employment status - are "self-employed" workers actually employees?
- Expenses - are reimbursements genuinely business expenses?
- Benefits in kind - are all taxable benefits reported on P11D?
- Tax codes - are correct codes being applied?
- NI categories - are correct categories used (especially for directors)?
- Statutory payments - are eligibility checks being done properly?
Preparing for a compliance check
- Gather records early - do not wait until the visit day
- Review your submissions - check RTI submissions for the review period
- Identify any errors - better to disclose voluntarily than be found out
- Prepare workspace - HMRC officer needs desk and privacy
- Nominate a contact - one person to liaise with the officer
- Consider representation - accountant or tax adviser can attend
During the check
- Be cooperative - obstruction can lead to penalties
- Answer honestly - do not guess, say if you need to check
- Take notes - record questions asked and answers given
- Request time - you can ask for time to find documents
- Ask questions - clarify anything you do not understand
After the check
HMRC will write to you with their findings:
- No issues - letter confirming compliance
- Minor issues - advice on improving processes
- Underpaid tax - assessment for additional tax plus interest
- Penalties - separate penalty notice if errors were careless or deliberate
