CIS statement redaction is the removal of identifiers from the payment and deduction statement a contractor gives a subcontractor. Finance Act 2004 s.61 makes the contractor deduct a sum on account of tax from a contract payment. The Income Tax (Construction Industry Scheme) Regulations 2005 set the statement that records it. anonym.plus marks the reference, the name, and the amount on your device.
When this applies
The deduction runs at 20% for a subcontractor HMRC has verified and 30% for one it has not. Gross payment status removes it altogether. The statement must reach the subcontractor within 14 days of the end of the tax month. It pairs a ten-digit Unique Taxpayer Reference with a trading name and a figure — exactly the set a shared copy should not carry.

- Local OCR reads a scanned copy if needed.

- Save the clean copy locally.
What you need to provide

Limitations & cautions
A sole trader with a rare deduction can be guessed even after the reference goes. The tool flags named items, not every indirect clue. The subcontractor is entitled to their own unredacted statement, so redact only the copy that travels further.
Frequently asked questions
Which rules sit behind a CIS deduction statement?
Finance Act 2004 s.61 sets the deduction from a contract payment. The Income Tax (Construction Industry Scheme) Regulations 2005 set the statement recording it, due within 14 days of the end of the tax month.
Why does the 20% or 30% rate matter on a shared copy?
It shows whether HMRC verified the subcontractor. Keep the rate and the gross figure so the record reconciles, and remove the reference and trading name instead.
Can I clean a stack of statements in one run?
Yes. Batch mode handles up to 20 files per local run, with OCR for scanned copies. A shared map keeps one subcontractor steady across them.
