The Construction Industry Scheme (CIS) sets out the special tax rules for subcontractors and contractors who work in the construction industry and how payments must be handled. 
You are a contractor under CIS if you engage subcontractors to perform any form of construction activity. As a contractor, you are required to register with HMRC, verify if your subcontractors are registered with HMRC, pay subcontractors after deducting tax and submitting monthly statements confirming these payments. 
You are a subcontractor under CIS if you work for a contractor. As a subcontractor, you are required to register with HMRC for CIS. You can act as self-employed subcontractor or via a limited company. Chart Accountancy can advise you choosing the most appropriate business structure for you.
