Construction Industry Scheme

Our team of construction business accountants can provide you with guidance and support when it comes to CIS registration and claims. We can help you to comply with the scheme and make the most of your profits, so that you can grow your business and keep making strides in the construction industry.


What is the Construction Industry Scheme?

The Construction Industry Scheme (CIS) is a government initiative which aims to ensure that contractors and subcontractors in the construction industry are paying the correct amount of tax. Under the scheme, contractors must register with HMRC for CIS and complete a monthly return.

As part of the return, contractors must declare how much money they have paid subcontractors and deduct a 20% tax from each payment. These deductions count as advance payments towards the subcontractor’s tax and National Insurance.

The scheme is designed to reduce the burden on small and medium sized construction businesses. We can give you advice on how to comply with these obligations, helping you to manage your tax liabilities.

What is covered by CIS?

CIS covers most construction work to buildings or structures, and civil engineering works like roads and bridges. That includes:

  • preparing the site,
  • demolition and dismantling,
  • building work,
  • alterations, repairs and decorating,
  • installation of heating, lighting, power, water and ventilation systems, and
  • cleaning the site after work is complete.
