Who the service is for
Start with the right checks.
CIS is a tax deduction scheme for construction work. To use our CIS service, the work and engagement must be suitable for self-employed payment. We assess the actual working arrangements, including supervision, direction or control over how the work is done.
A UTR or CIS registration alone does not confirm eligibility. If CIS is not appropriate, we’ll explain the reason and discuss the available route.
Registration and verification
We’ll guide you through getting set up.
Tell us about your assignment and agency. We’ll explain the information needed for our assessment, registration and HMRC verification. Once the checks are complete, we’ll confirm the service terms, NWM’s margin and the payment arrangements.

Deductions and payment
See what has been deducted and why.
We use HMRC’s verification result to apply the appropriate CIS treatment. Your payment information shows NWM’s margin and any CIS deduction, so you can follow the calculation.
CIS deductions count towards your tax and National Insurance liability. They are not necessarily your final tax bill. You remain responsible for your tax return and any balance due.
Support and information
Keep your records within reach.
Access your payment information through your personal portal. Need a statement or help understanding a deduction? Contact the team and we’ll help you find what you need.
We’ll also make a courtesy call after your first week of being paid through NWM, then every four weeks while you use us, to check how things are going.
