What Is CIS Status?
CIS (Construction Industry Scheme) status refers to a tax deduction system used by HM Revenue & Customs (HMRC) in the UK construction industry. The scheme requires contractors deduct tax from payments made to subcontractors and pass it directly to HMRC as an advance payment towards the subcontractor’s tax and National Insurance liabilities.
Why Does CIS Status Matter?
Before discussing how to check CIS status, let’s explain why CIS status matters and why maintaining a good CIS status is essential.
Cash Flow
A higher deduction rate of 30% can severely affect a subcontractor’s working capital compared to the standard 20% or 0% gross payment.
Compliance and Penalties
Proper registration and adherence to the scheme’s rules help reduce the risk of fines or legal complications from HMRC.
Business Credibility
Contractors prefer working with verified, compliant subcontractors. This can lead to more work opportunities and stronger business relationships.
Simplified Tax Management
Correct deductions at source can simplify year-end tax returns and reduce the risk of a large, unexpected tax bill.
How to Check CIS Status: Step-by-Step Process
Before paying a new subcontractor, you must check their status with HMRC to determine the accurate deduction rate.
Step 1: Gather Required Information
You need specific details about the subcontractor, which must exactly match the information they used to register with HMRC:
Your own details:
- Unique Taxpayer Reference (UTR)
- HMRC accounts office reference
- HMRC employer reference
Subcontractor’s details:
- For a sole trader: Name, UTR, and National Insurance number
- For a limited company: Company name, company UTR, and company registration number
- For a partnership: Trading name, partnership UTR, and the UTR or company registration number of each partner
Step 2: Choose Your Verification Method
The second step of “how to check CIS status” is choosing the verification method. You can verify a subcontractor using one of the following methods:
- Online (recommended): Use the free HMRC CIS online service.
- Commercial software: Use a third-party commercial software package that can handle the CIS verification check.
- By phone: In certain cases, you may need to call the CIS helpline to verify up to 10 subcontractors per call.
Step 3: Complete the Verification
The third step of checking CIS status is following the online or phone prompts to submit the subcontractor’s details. HMRC will then tell you:
- Whether the subcontractor is registered for the scheme.
- The rate of deduction to use:
- 0% (gross payment): no deductions are necessary.
- 20% (standard rate): for registered subcontractors.
- 30% (higher rate): for subcontractors who are not registered.
Step 4: Record the Details
The last step of how to check CIS status is recording the details. HMRC will provide you with a verification reference number. You must keep a record of this number and the date of verification. You need this number for your monthly returns and to give to the subcontractor on their payment and deduction statements.
When Do You Need To Verify a Subcontractor under CIS?
Now that you understand how to check CIS status, it’s important to know when verification is required. A contractor must verify a subcontractor with HMRC before making their first payment. Re-verification is required if the contractor has not paid the subcontractor within the current and the previous two tax years.
- Before the first payment: You must verify every new subcontractor with HMRC before you make any payment to them.
- Re-verification (after a break): If you previously used a subcontractor but have not made any payments to them within the current and two previous tax years, you must verify them again to get their current payment status.
- Status changes: HMRC will typically inform you if a subcontractor’s payment status changes (e.g., from a 20% deduction rate to gross payment status). However, you must still ensure your verification information is up to date in the HMRC system to receive these notifications.
What Information Is Required To Verify a CIS Subcontractor?
Understanding how to check CIS status is essential to dictate how much money a worker receives and ensure both subcontractors and contractors remain HMRC compliant. However, you should also know how to verify a CIS subcontractor.
You can verify the subcontractors using the HMRC CIS online service or a commercial CIS software. To do that, you will require the following information:
- You will need your own HMRC Unique Taxpayer Reference (UTR) and employer reference number.
- The details of the subcontractor, which can vary according to the type of business:
- Sole Trader: UTR and National Insurance Number
- Limited Company: Company name, company UTR, and registration number
- Partnership: Trading name, partnership UTR, and the UTR/registration number of the nominated partner.
How You Can Verify Your CIS Status?
While “how to check CIS status” is vital to determine cash flow and legal liability, it is also crucial to discuss how to verify CIS status. You can verify your CIS status by following this process step-by-step:
- Sign in to your HMRC CIS online service account and enter the required information.
- Once logged in, navigate the CIS section to view your current status.
- You will need your UTR and NI number for security verification.
- Ask your contractor if they verified you before their first payment. They will have a record of the deduction rate HMRC instructed them to use.
What Is HMRC’s Response To CIS Subcontractor Verification?
HMRC’s response provides the definitive instruction on how to pay the subcontractor:
- HMRC checks the details like UTR, NI number or company registration number against their records. They then inform the contractor of the correct deduction rate to apply (0%, 20%, or 30%).
- If HMRC cannot verify the subcontractor, the contractor is instructed to apply the higher 30% deduction rate. The subcontractor is then advised to contact HMRC to register and complete an identity check.
- HMRC notifies both the contractor and the subcontractor if the subcontractor’s payment status changes (e.g., from net payment to gross payment status).
How to Check CIS Status as a Subcontractor?
This section explains how to check CIS status as a subcontractor by using HMRC’s online services or by contacting them directly.
Online

By Phone
You can call the HMRC Construction Industry Scheme helpline on 0300 200 3210 for general queries or to confirm your status.
Through Your Contractor
When you start work, your contractor is required to verify your status with HMRC before paying you. They will then be told the correct deduction rate to apply (20%, 30%, or 0% for gross payment status).
They must provide you with a monthly payment and deduction statement, which serves as a record of your status and the tax deducted.
Through an Accountant
An accountant or tax specialist can also check your status, manage your records, and assist with any applications for gross payment status.
How to Check CIS Status If It’s Incorrect?
If your CIS status is incorrect, it can result in the wrong amount of tax being deducted. It can impact your finances and potentially lead to compliance issues with HMRC. Follow these steps to correct an incorrect CIS status:
Check Your Status
You can check your official CIS status by signing in to your HMRC online service account. Contractors must also verify a subcontractor’s status with HMRC before making any payments.
Contact HMRC
You can contact the HMRC CIS helpline if you find a status that you believe is wrong.
Provide Necessary Information
Sometimes, it may be necessary to include details such as a UTR and National Insurance number, as well as business information, so they can identify who you are and update their records accordingly.
Re-register/Apply for Gross Payment Status
- If you are not registered, then you must register as a subcontractor with HMRC to get the standard 20% deduction rate.
- To be paid in full, with no deductions, if you are eligible, you need to apply for gross payment status via the GOV.UK website.
Claim Refunds
If you have too much tax deducted because of an incorrect status, then you can claim a refund of overpaid tax through your annual Self Assessment or Corporation Tax return.
How to Keep Your CIS Status In Good Standing?

Registration With HMRC

Pay Your Tax On Time

Keep Accurate Records
You should maintain accurate records of all payments, deductions, invoices, and material costs that are relevant for at least three years after the relevant tax year. HMRC can request these records at any time.
Report Changes Quickly
If there are any changes in your business regarding the name, address, or structure of your business, inform HMRC as soon as possible.
Correct Verification
Ensure that, if you are a subcontractor, you provide your correct legal name/trading name and UTR to your contractor for verification at HMRC.
Monitor Annually
HMRC conducts an annual review of businesses with gross payment status to ensure that they continue to meet the compliance criteria. Staying on top of all your tax obligations is crucial to passing this review and retaining your status.
