Construction Industry Scheme (CIS)

If you’ve been working in the construction industry for a while, you’re probably familiar with the Construction Industry Scheme (CIS). It’s an essential part of UK tax law designed specifically for contractors and subcontractors, ensuring that the correct amount of tax and National Insurance is paid to HM Revenue & Customs (HMRC).

CIS requires contractors to deduct money from subcontractors’ payments before they are made. These deductions are passed directly to HMRC and contribute towards the subcontractor’s tax and National Insurance obligations. Understanding how to navigate the complexities of CIS can be daunting, but with expert help from Frank’s Accountants, you can ensure full compliance while optimising your business’s tax position.

 

Understanding the rules of the CIS Scheme

The Construction Industry Scheme (CIS) is a set of rules introduced by HMRC for the construction sector, requiring contractors to deduct money from subcontractors to cover their tax and National Insurance contributions. The scheme is designed to reduce tax evasion in the construction industry by ensuring that subcontractors’ tax is paid upfront.

Whether you’re a contractor or a subcontractor, CIS can affect how you manage payments, tax deductions, and your overall cash flow. Our experienced accountants at Frank’s Accountants are here to help you manage CIS correctly and stay compliant with HMRC regulations.

Who Does CIS Apply To?

CIS applies to:

  • Contractors: Businesses or individuals paying subcontractors for construction work.
  • Subcontractors: Those carrying out construction work for a contractor.

Even if your main business is not in construction, you may still need to register for CIS if you regularly hire subcontractors for construction work.

 

CIS Deductions Explained

Under CIS, contractors are required to make deductions from subcontractors’ payments. These deductions, typically 20% or 30%, are sent to HMRC. The amount deducted depends on whether the subcontractor is registered under CIS.

  • Registered Subcontractors: Have 20% deducted from their payments.
  • Unregistered Subcontractors: Have 30% deducted until they register with HMRC.

These deductions are later credited towards the subcontractor’s annual tax bill.

This is accountancy as it should be done! Sam and the crew are as expert as it gets, always ready to offer support and expert advice and to assist in the seemingly endless interactions with HMRC. I really cannot recommend them highly enough. crawl on your bended knees over broken glass if you have to, but get to Franks accountants and leave them to take care of all the stuff you thought you understood ( but didn't!) Thank you all!
