FAQs

Registration faqs 1
What is CIS subcontractor verification?

CIS subcontractor verification is the process contractors use to confirm with HMRC that a subcontractor is registered and to establish the appropriate payment status and deduction rate.

Do subcontractors need to register for CIS?

Subcontractors carrying out construction work should register for CIS if they do not want deductions made at the higher rate. HMRC provides registration routes for different business structures, including limited companies.

What information is needed for CIS verification?

Depending on the subcontractor's structure, HMRC may require information such as the UTR, National Insurance number, company registration number, legal name or trading name. The details need to match HMRC's records.

What happens if a subcontractor cannot be verified?

If HMRC cannot match the subcontractor's details, the subcontractor may be treated as unmatched and the higher deduction rate may apply until the position is resolved.

What is the CIS deduction rate?

The standard CIS deduction rate is 20% for registered subcontractors. A 30% higher rate can apply where the subcontractor is not registered or cannot be verified. Some subcontractors may qualify to receive payments gross.

Can you help with Gross Payment Status?

Yes. We can support eligible construction businesses with the Gross Payment Status application and help review the relevant requirements.

Does a subcontractor need to be verified every month?

Not necessarily. HMRC generally requires re-verification when the subcontractor has not been included on a CIS return in the current or previous two tax years.

Can you help with unmatched CIS verification?

Yes. We can review the information submitted, identify potential mismatches and help resolve the registration or verification issue.
