The Construction Industry Scheme (CIS) is a set of special rules for handling payments for construction work that contractors make to subcontractors. The scheme covers all ‘construction operations’ – construction work – carried out in the UK, as well as some other related work.
Under the Construction Industry Scheme (CIS), contractors deduct money 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. Construction workers under this scheme can claim a tax refund for expenses.
