What is the Construction Industry (CIS) Scheme?
The Construction Industry Scheme (CIS) is a tax deduction scheme where contractors deduct money at source from a subcontractor’s payments and pass it to HM Revenue and Customs (HMRC).
The deductions count as advance payments towards the subcontractor’s tax and National Insurance.
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.
