What is the Construction Industry Scheme (CIS)?
The Construction Industry Scheme (CIS) is a government-run scheme that applies to contractors and subcontractors working in construction.
Under CIS:
- Contractors must deduct tax from subcontractor payments
- These deductions are then paid to HMRC on the subcontractor’s behalf
- Subcontractors registered under CIS are typically taxed at a lower rate, while unregistered workers are taxed at a higher rate
- Arch Finance manages this entire process, ensuring all deductions are calculated and submitted accurately.
Understanding employment status
Not all workers in construction fall under CIS.
CIS applies to self-employed subcontractors only. Employment status must be determined correctly, as it impacts how workers are paid and taxed.
Built for contractors and agencies
Whether you’re a subcontractor looking for a simple, reliable CIS solution or an agency managing multiple workers, Arch Finance provides a service designed to scale, support, and simplify.
With a focus on accuracy, compliance, and service, we make CIS straightforward.
