Construction Industry Scheme (CIS)

The Construction Industry Scheme (CIS) is a scheme that applies to payments made to self-employed workers and businesses within the Construction Industry.

Construction Industry Scheme Guidance

Contractors deduct money from a subcontractor’s payments and pass it to HM Revenue and Customs (HMRC). HMRC Guidance:

  • Contractors must register for the scheme.
  • Subcontractors do not have to register, but deductions are taken from their payments at a higher rate if they are not registered.

Standard rate, at this time, is 20% of all labour payments for registered subcontractors. The higher rate is 30% for non-registered subcontractors.

  • These deductions count as advance payments towards the subcontractor’s tax and National Insurance.

Who Counts as a Contractor or Subcontractor?

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

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

However, you must register as both if you fall under both categories.

Work covered by Construction Industry Scheme

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. For example, 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

CIS Exceptions

You do not 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. For instance, running a canteen or site facilities

The CIS guide for contractors and subcontractors provides more detail on what is, and is not, covered by the scheme.

Is your business based outside the UK?

In short, the same CIS rules apply if your business is based outside the UK, but you do construction work as a contractor or subcontractor in the UK.
