Payroll audit file redaction is the removal of personal identifiers from the bundle a reviewer works through. Finance Act 2008 Sch. 36 lets HMRC require documents by taxpayer notice, reach a third party by notice, and inspect business premises. Audit bundles are assembled under real pressure. anonym.plus marks each name and number on your device, so the figures stay useful.
When this applies
A minimum wage check has its own teeth. National Minimum Wage Act 1998 s.14 gives an enforcement officer power to require records. A notice of underpayment under s.19 carries a penalty of up to 200% of the arrears, capped at £20,000 per worker, alongside possible naming. Bundles built for that review circulate to advisers who need the figures, not the names.
How anonym.plus handles it
- Point anonym.plus at the review folder on your device.
- Local OCR reads any scanned pages in the set.
- The tool flags names, NI numbers, and amounts.
- A shared map keeps repeat workers steady.
- Check the summary and fix low-confidence flags.
- Save the clean set locally.
What you need to provide
- A folder of files (PDF, XLSX, mixed).
- The shared map turned on for steady results.
- An operator (Replace works well for a bundle).

Limitations & cautions
Give the reviewer what the notice actually asks for. Redaction is for the working copies that circulate around an audit, not for a response to an information notice. A mixed bundle also leans on OCR for scans, so review low-confidence flags.
Frequently asked questions
Can I redact documents HMRC has formally requested?
No. A Finance Act 2008 Sch. 36 information notice asks for the document itself. Redact only the internal working copies that travel around the review.
What is at stake in a minimum wage check?
A notice of underpayment under National Minimum Wage Act 1998 s.19 can carry a penalty of up to 200% of the arrears, capped at £20,000 per worker, on top of paying the arrears.
How does a bundle stay internally consistent?
A shared map logs each worker once, so the same person carries the same alias across registers, slips, and time records in the set.
