Understanding CIS verification: Navigating the process for construction businesses

Apr 10, 2024

The Construction Industry Scheme (CIS) simplifies financial compliance for all businesses by enabling upfront tax deductions for subcontractors.

However, the verification process at the heart of CIS can seem complex and burdensome.

This guide aims to demystify verification step-by-step – equipping contractors and subcontractors alike with the knowledge needed to complete this critical procedure quickly and correctly.

Understanding CIS verification

Contractors must take CIS verification into account before they make payments to subcontractors.

It determines the tax rate HMRC expects contractors to deduct from payments, ensuring subcontractors contribute appropriately to their tax and National Insurance contributions.

This system helps prevent tax evasion and maintains fairness within the construction sector.

CIS verification: step-by-step

So, how do you initiate and manage the CIS verification process? Here’s a step-by-step guide:

Step 1: Registering for CIS

First and foremost, ensure your business is registered with HMRC as a contractor, subcontractor, or both. This registration is a prerequisite for accessing the CIS online service, which you’ll need for verification.

Step 2: Collecting subcontractor information

Before verification, collect all necessary details from your subcontractors, including their Unique Taxpayer Reference (UTR) and business name. For limited companies, you’ll also need their company registration number.

Step 3: Using the HMRC CIS online service

The HMRC CIS online service is the most efficient way to verify subcontractors. After logging in with your Government Gateway ID, navigate to the CIS section to add and verify subcontractors.

The system instantly provides a verification number and the subcontractor’s deduction rate.

Step 4: Understanding the deduction rates

When you verify subcontractors through the online system for the Construction Industry Scheme (CIS), you’ll encounter one of three deduction rates for each, which informs how you manage their payments:

  1. Subcontractors with Gross Payment Status: These subcontractors receive their payments without deductions, indicated by a 0% rate. To qualify, subcontractors must prove they have a good tax payment record, conduct their business using a bank account in the UK, and satisfy a specific turnover requirement. This status shows they’re compliant with their tax responsibilities.
  2. Registered Subcontractors without Gross Payment Status: These are subcontractors registered in the CIS but not approved for gross payment. The system will show a standard 20% deduction rate for them. This means you need to deduct 20% from their payments and send this to HMRC, which counts towards their tax and National Insurance.
  3. Unregistered Individuals: A higher deduction rate of 30% is applied for subcontractors not registered with CIS. This higher rate compensates for the increased risk of non-compliance with tax obligations, and like with registered subcontractors, the deducted amount is paid to HMRC.

Step 5: Record keeping

Maintaining detailed records of all verifications, including subcontractor details and their respective deduction rates, is essential.

These records are invaluable for resolving any disputes or inquiries from HMRC.

Practical tips for smooth CIS verification

Four core tips for smooth CIS verification include:

  • Regularly update subcontractor details: Ensure subcontractor information is current to avoid verification delays.
  • Stay informed: Keep ahead of any changes in CIS regulations to ensure compliance.
  • Leverage technology: Accounting software can streamline CIS to simplify deductions and record-keeping.
  • Seek professional advice: Consulting with a tax professional can provide clarity and direction for complex situations.

Why CIS compliance matters

Compliance with CIS is not just about adhering to legal requirements – it has broader implications for your business and the industry at large. Here’s why CIS compliance is crucial:

  • Failure to comply can result in financial penalties from HMRC. Proper CIS management reduces the risk of tax underpayments and the associated interest or penalties.
  • Fair treatment of subcontractors is a cornerstone of ethical business practices within the construction industry.
  • CIS compliance ensures subcontractors are taxed according to their registered status with HMRC.
  • This system promotes fairness by ensuring subcontractors’ tax deductions are handled correctly and transparently.
  • Compliance with CIS demonstrates a business’s commitment to transparency and ethics.
  • This commitment can enhance a business’s reputation among peers, clients, and regulators, building trust and reliability.
