CIS Verification & HMRC Compliance Software

The Problem

Manual CIS checks are slow — and screenshots get lost when you need proof later.

What Changes

Verify subcontractors, store evidence with timestamps, and keep a compliance record that’s easy to audit and easy to maintain.

How It Works

Verification is only useful if you can prove it later. Keep the check and the evidence together.

Record the identifiers you need for CIS verification and keep them tied to the subcontractor profile.
2
Run CIS verification
Perform a verification workflow and store the result in the subcontractor record.

Keep the outcome and timestamps so compliance isn’t dependent on someone saving screenshots.
4

5
Export records
Produce a clear audit record for internal governance and HMRC queries.

FAQ

Frequently Asked Questions

Common questions teams ask before they book a demo.

CIS verification is the process of checking a subcontractor’s status under HMRC’s Construction Industry Scheme so you apply the correct treatment and keep compliant records.

Site Samurai supports HMRC-led CIS verification workflows so you can store outcomes and maintain evidence within your subcontractor records.

Yes. Keep a consistent process across subcontractor types and store outcomes in the same place.

You typically need the verification outcome and when it was performed. Site Samurai keeps the evidence tied to the subcontractor record so it’s easy to retrieve.

Many teams verify on onboarding and re-check when key details change. The important thing is to keep a consistent process and evidence trail.

No. CIS verification is part of compliance and record keeping. Payroll/accounting systems still handle payroll runs and submissions.
