Navigating a HMRC CIS Compliance Check: A Comprehensive Guide

Here, we provide an overview of CIS compliance checks, outlining what to expect and how we can help you brings matters to a conclusion.


What is the Construction Industry Scheme?

The Construction Industry Scheme is a set of regulations introduced by HMRC to streamline and ensure the proper taxation of construction work. Under CIS, contractors deduct money from subcontractors' payments and pass it to HMRC. These deductions count as advance payments towards the subcontractor's tax and National Insurance. The scheme applies to all construction work carried out in the UK, including site preparation, alterations, dismantling, repairs, decorating, and demolition.


Key components of CIS include:

  • Registration: Contractors must register for the scheme. Subcontractors can choose to register, which allows for a lower rate of deduction.

  • Verification: Before making payments to subcontractors, contractors must verify their CIS status with HMRC.

  • Deductions: Contractors deduct a portion of the payment to cover subcontractors' tax liabilities. The standard deduction rates are 20% for registered subcontractors and 30% for unregistered ones.

  • Monthly returns: Contractors submit monthly returns to HMRC, detailing all payments made to subcontractors and the corresponding tax deductions.


What is a Compliance Check in Relation to CIS?

A CIS compliance check is an examination conducted by HMRC to ensure that businesses in the construction industry are adhering to CIS regulations. These checks can be routine or triggered by discrepancies in tax submissions or business operations. The primary objectives of these checks are to verify:


  • Accurate deduction and reporting of tax by contractors.

  • Proper registration and verification of subcontractors.

  • Correct submission of monthly returns and payments.


Focus Areas During a CIS Compliance Check

During a compliance check, HMRC will review the contractor’s records and processes to ensure they are meeting CIS requirements. This involves checking documentation, verifying the accuracy of deductions and payments, and assessing the timeliness and accuracy of monthly returns.
