Who Needs to Follow the Construction Industry Scheme?
We cover our CIS services for:
Â
- Contractors must register for the scheme.
- Subcontractors don’t have to register, but deductions are taken from their payments at a higher rate if they’re not registered.
- Subcontractors or those deploying services of subcontractors for construction works are liable for tax assessment under the Construction Industry Scheme (CIS). As a subcontractor, one needs to be verified by the principal contractor.
- CIS applies to you even if construction isn’t your core activity, but you spend significantly on it each year. For example, CIS may also apply to non-construction companies like housing associations and local authorities that spend over £1 million annually on construction.
- This scheme also covers labour agencies, property developers, and gang leaders.
