What is CIS?

Under the Construction Industry Scheme (CIS), contractors deduct money from subcontractor’s payments and pass it on to HM Revenue and Customs (HMRC).

The deductions count as advance payments towards your subcontractor tax and National Insurance.

If you are a Contractor you must register for the scheme.

If you are a Subcontractor you don’t have to register, but deductions will be taken from your payments at a higher rate if you are not registered.

Who counts as a contractor or subcontractor?

You need to Register as a contractor if either:

  • you pay subcontractors for construction work, or;
  • your business doesn’t do construction work but you spend an average of more than £1 million a year on construction in any 3-year period

And you need to Register as a subcontractor if you do construction work for a contractor.

  • You must register as both if you fall under both categories.

Work covered by CIS

CIS covers most construction work to:

  • a permanent or temporary building or structure
  • civil engineering work like roads and bridges

For the purpose of CIS, construction work includes:

  • preparing the site, eg laying foundations and providing access works
  • demolition and dismantling
  • building work
  • alterations, repairs and decorating
  • installing systems for heating, lighting, power, water and ventilation
  • cleaning the inside of buildings after construction work


You don’t have to register if you only do certain jobs, including:

  • architecture and surveying
  • scaffolding hire (with no labour)
  • carpet fitting
  • making materials used in construction including plant and machinery
  • delivering materials
  • work on construction sites that’s clearly not construction, eg running a canteen or site facilities
