What is the CIS? Guide to the Construction Industry Scheme

What is the Construction Industry Scheme (CIS)? In this post we look at what the scheme is, whether it applies to you and if you are a contractor or subcontractor.

In the Construction Industry Scheme (CIS), contractors deduct money from subcontractors‘ payments and pass it on to HM Revenue and Customs (HMRC). Subcontractor deductions count as advance payments towards the subcontractor’s taxes and NI.

Contractors must register for the scheme. Subcontractors are not required to register, but if they aren’t, deductions are taken from their payments at a higher rate.

You must register as a contractor if either:

  • you pay subcontractors for construction work
  • your business does not do construction work but you have spent more than £3 million on construction in the 12 months since you made your first payment

If you do construction work for a contractor then you will need to register as a subcontractor .

The Construction Industry Scheme (CIS) covers most construction work to buildings, including site preparation, decorating and refurbishment.

The same CIS rules apply if your business is based outside the UK, CIS rules apply if your business is not based in the UK, but you perform construction work as a contractor or subcontractor in the UK.
