CIS Return

What us a CIS return?

It cannot be obvious to understand the requirements of CIS returns, so we are here to provide our knowledge and understanding to help manage this for you.


A CIS monthly return is a core element of the Government’s Construction Industry Scheme (CIS). The Government introduced CIS to reduce fraud and tax evasion levels in the construction industry and help sub-contractors spread their tax liabilities over the financial year. CIS requires contractors to withhold 20 or 30 percent of any payment due to a subcontractor and pay the deduction to HMRC via the CIS monthly return. CIS covers the following types of work when it is carried out by subcontractors:

  • Alterations
  • Building work
  • Decorating
  • Demolition or dismantling
  • Installation of heating, lighting, power, water and ventilation
  • Repairs
  • Site preparation

What expenses can I claim for?

A key part of working with the Self Assessment system is understanding what expenses you can claim. This is an area where many people on Self Assessment miss out and end up paying too much tax. Examples of allowable expenses in construction include:


  • Work travel costs.
  • Essential tools and equipment.
  • Materials you need for work.
  • General costs of running your business, from stationery to advertising.
  • Accountancy fees.

These are the essential business costs, and they count against the income you're being taxed on.
