HMRC Verification

Fast, accurate CIS verification for contractors and agencies

NZTWorx verifies your subcontractors directly with HMRC and confirms the correct CIS deduction rate (gross, 20% or 30%) before the first payment. We capture and validate the details you supply, resolve mismatches, and return a verification reference along with the rate so your payroll stays compliant.

Use us for one-off checks, bulk onboarding ahead of a project, or continuous re-verification. We maintain a full audit trail and integrate the verified rate into your CIS payroll and statements, reducing risk and admin across finance and site teams.

If a worker’s status changes, we re-verify and alert you before the next cycle—keeping deductions correct and helping you avoid penalties or rework.

Key benefits

  • Live HMRC verification with clear confirmation of gross/20%/30% rate

  • Bulk onboarding for new projects with duplicate detection and data cleaning

  • Full audit trail: inputs, verification reference, outcome and timestamp

  • Automatic re-verification on schedule or when details change

  • Seamless handoff into weekly CIS payroll and deduction statements

What’s included

Identity & Scheme Checks

Validation of UTR, name and NI/company details; scheme status confirmation and rate outcome recorded for audit.

Bulk Verification

Secure CSV upload for large crews; de-dupe, field validation and consolidated results ready for import to payroll.

Reporting & Audit

Verification references, outcomes and timestamps per worker, with exportable logs for finance and compliance.

CIS Payroll Handoff

Verified rates passed straight into CIS payroll, deduction statements and optional CIS300 preparation.

How it works

  1. Send your subcontractor details (name, UTR, NI or company number, contact info) individually or via secure CSV.

  2. We run live HMRC verification and capture the official rate and verification reference.

  3. Any mismatches are flagged with guidance to correct and re-submit quickly.

  4. Verified rates flow into your CIS payroll so deductions are correct from the first payment.

  5. We schedule re-verification and provide exports and logs for audit and month-end.

Compliance & risk reduction

Incorrect or missing verification can lead to over/under deductions, reprocessing and potential penalties. Our controls ensure each worker has a current verification reference and the correct rate applied, with alerts on any change before payroll runs.

We retain the evidence you need: inputs submitted, HMRC outcome, reference, timestamp and user, making audits straightforward.

What we need to start

  • Your contractor details and CIS scheme status

  • Subcontractor list with UTR and NI/company number, plus legal name

  • Preferred verification mode (single entries or bulk CSV upload)
