CIS Check: A Comprehensive Guide for UK Tradespeople

What is the Construction Industry Scheme (CIS)?

Before diving into the specifics of CIS checks, it’s essential to understand the broader context of
the Construction Industry Scheme. The CIS is a tax deduction scheme operated by HM
Revenue and Customs (HMRC) in the UK. It applies to contractors and subcontractors in the
construction industry, aimed at ensuring proper tax compliance and reducing tax evasion.
Under the CIS, contractors deduct money from subcontractors’ payments and pass it directly to
HMRC. These deductions count as advance payments towards the subcontractor’s tax and
National Insurance contributions. The scheme affects various trades within the construction
industry, including builders, plumbers, electricians, and many others.

Understanding CIS Numbers

At the heart of the CIS check process is your CIS number. This unique identifier is crucial for your operations within the construction industry. Let’s break down what you need to know about CIS numbers:

What is a CIS Number?

A CIS number, also known as a Unique Taxpayer Reference (UTR), is a 10-digit number assigned to you by HMRC. This number is used to identify you within the Construction Industry Scheme and is essential for all your CIS-related transactions and communications with HMRC.

How to Obtain Your CIS Number

If you’re new to the construction industry or haven’t worked under the CIS before, you’ll need to register with HMRC to obtain your CIS number. Here’s how:

1. Register as self-employed with HMRC if you haven’t already done so.
2. Register for the CIS through the HMRC website or by phone.
3. Provide necessary information, including your National Insurance number and business details.
4. Once registered, HMRC will provide you with your UTR, which serves as your CIS number.

Importance of Your CIS Number

Your CIS number is crucial for several reasons:

• Verification: Contractors use this number to verify your status with HMRC before making payments.
• Payment Processing: It determines the rate of deduction applied to your payments (standard rate or higher rate).
• Tax Returns: You’ll need your CIS number when filing your Self Assessment tax return.

The CIS Check Process

The CIS check, or verification process, is a crucial step that contractors must undertake before paying their subcontractors. Here’s what you need to know about this process:

What is a CIS Check?

A CIS check is the process by which a contractor verifies a subcontractor’s status with HMRC. This check determines whether the subcontractor is registered with the CIS and what rate of deduction should be applied to their payments.

How is a CIS Check Performed?

Contractors can perform a CIS check in several ways:

1. Online: Through the HMRC CIS online service
2. Phone: By calling the HMRC CIS helpline
3. Commercial Software: Using HMRC-approved third-party software

To perform the check, the contractor will need the subcontractor’s name, UTR (CIS number), and National Insurance number.

Outcomes of a CIS Check

After performing a CIS check, there are three possible outcomes:

1. Registered for CIS: Payments are subject to a 20% deduction for tax and NI contributions.
2. Registered for Gross Payment: No deductions are made, and the subcontractor receives full payment.
3. Unregistered: Payments are subject to a higher 30% deduction rate.

Managing CIS Deductions

Understanding how CIS deductions work is crucial for managing your finances effectively as a subcontractor. Here’s what you need to know:

How CIS Deductions Work

When you’re paid as a subcontractor under the CIS, your payments may be subject to deductions:

• If you’re registered for CIS, the contractor will deduct 20% from your payments.
• If you’re unregistered, the deduction rate is higher at 30%.
• These deductions are forwarded to HMRC as advance payments towards your tax and NI contributions.

Tracking Your CIS Deductions

Keeping accurate records of your CIS deductions is crucial. Here’s why:

• It helps you understand your true income after deductions.
• You’ll need this information when filing your Self Assessment tax return.
