CIS Subcontractor Verification Record (UK)

A CIS Subcontractor Verification Record in the United Kingdom sets the scope of works, price, programme, and payment terms for the building or installation project, with its requirements set by the Freedom of Information Act 2000.

Before making the first payment to any new subcontractor, every registered contractor must verify the subcontractor's status with HMRC. Verification can be completed online through HMRC's CIS online service, by telephone on 0300 200 3210, or through HMRC-recognised commercial payroll software. HMRC will confirm one of three deduction rates: 20% for subcontractors who are registered under CIS with standard net payment status; 30% for unregistered or unverified subcontractors; or 0% (gross payment) for subcontractors who have been granted gross payment status after demonstrating a satisfactory compliance record and meeting HMRC's turnover test under regulation 25 of the Income Tax (Construction Industry Scheme) Regulations 2005.

Upon completing the verification, HMRC issues a verification reference number — a unique alphanumeric code — which the contractor must record. The CIS Subcontractor Verification Record documents this reference number, the subcontractor's Unique Taxpayer Reference (UTR), National Insurance number, and the confirmed deduction rate. HMRC requires contractors to retain these records for at least three years from the end of the relevant tax year under the general record-keeping obligations of the Taxes Management Act 1970.

The CIS Subcontractor Verification Record is distinct from the CIS monthly return (submitted via the HMRC CIS online service or payroll software by the 19th of each month), the payment and deduction statement (which the contractor must provide to each subcontractor within 14 days of the end of each tax month in which a payment was made), and the HMRC CIS registration certificate. The verification record is the contractor's internal document confirming that the mandatory pre-payment verification step was completed and documenting the deduction rate authorised by HMRC for use in subsequent payments.

The CIS applies to most construction work carried out in the United Kingdom, including building, demolition, installation of heating and electrical systems, site preparation, repairs, decoration, and civil engineering. Businesses that spend more than £3 million on construction work in any 12-month period are treated as 'deemed contractors' under regulation 20 of the 2005 Regulations even if construction is not their primary business activity.

The legal framework governing the CIS Subcontractor Verification Record (UK) in United Kingdom draws on several key statutes and regulatory bodies. Under UK law, the UK GDPR and Data Protection Act 2018 apply to personal data processed under this agreement. The Consumer Rights Act 2015, enforced by the Competition and Markets Authority (CMA), protects consumer rights. Section 43 of the Companies Act 2006 governs company names. The Employment Tribunal adjudicates employment disputes under the Employment Rights Act 1996. The High Court of Justice and County Court have jurisdiction for civil matters under the Senior Courts Act 1981. Parties executing a CIS Subcontractor Verification Record (UK) in United Kingdom should confirm the document reflects current law, including any amendments enacted since the original drafting date. The Freedom of Information Act 2000 sets the foundational requirements.

A CIS Subcontractor Verification Record is needed whenever a registered CIS contractor engages a new subcontractor and must verify that subcontractor's status with HMRC before making the first payment — a mandatory step under the Income Tax (Construction Industry Scheme) Regulations 2005.

A principal contractor engaging a bricklaying, roofing, or electrical subcontractor for the first time on a construction site must verify the subcontractor's CIS registration status before issuing the first payment. Without verification, the contractor must deduct tax at the 30% higher rate, which increases the subcontractor's cash flow burden and may damage the commercial relationship. The verification record confirms which rate HMRC has authorised for that subcontractor.

A property developer commencing a new residential or commercial development project who builds their subcontractor supply chain from scratch must verify each subcontractor — whether sole trader, partnership, or limited company — before the first payment. HMRC requires the contractor to collect the subcontractor's UTR and, for individuals, their National Insurance number as part of the verification process. The verification record serves as evidence that the contractor completed this due diligence step.

A facilities management company or maintenance contractor classified as a 'deemed contractor' under regulation 20 of the 2005 Regulations — because its annual spend on construction operations exceeds £3 million — must comply with full CIS obligations including subcontractor verification. The verification record documents each subcontractor verification for the purposes of the deemed contractor's HMRC compliance.

A main contractor who took on a subcontractor in a previous tax year but has not made any CIS payments to that subcontractor in the current tax year — meaning there has been a gap of two or more consecutive tax months with no payment — must re-verify the subcontractor before resuming payments. The re-verification may produce a different deduction rate if the subcontractor's CIS status has changed. A new verification record should be prepared for each re-verification.

During an HMRC compliance visit or CIS audit, an inspector will request evidence that the contractor verified each subcontractor before making the first payment. The CIS Subcontractor Verification Record, retained for at least three years under the Taxes Management Act 1970, provides the required documentary evidence and reduces the risk of penalties under Schedule 55 of the Finance Act 2009.

A CIS Subcontractor Verification Record must include the following elements to satisfy HMRC's record-keeping requirements under the Income Tax (Construction Industry Scheme) Regulations 2005 and the Taxes Management Act 1970.

The contractor identification block must state the contractor's full legal name or business name, HMRC employer reference number (ERN), and CIS registration reference. For companies, the Companies House registration number should also be included. These details link the verification record to the contractor's CIS monthly returns and HMRC registration.

The subcontractor identification section must include the subcontractor's full legal name or, for companies and partnerships, the registered business name. For sole traders, the National Insurance number must be recorded. For limited companies, the company registration number and UTR must be stated. For partnerships, the partnership UTR and the UTR of each individual partner must be recorded. Accurate subcontractor identification is critical because HMRC's verification service matches these details against the CIS register.

The Unique Taxpayer Reference (UTR) is a 10-digit number assigned by HMRC to each taxpayer and is the primary identifier used in the CIS verification process. The subcontractor must provide their UTR before verification can proceed. A subcontractor without a UTR cannot be verified as registered and will attract the 30% higher deduction rate until they obtain one from HMRC.

The verification reference number issued by HMRC upon completion of the verification must be recorded precisely. This alphanumeric reference is the contractor's evidence that the verification was completed and should be retained for at least three years. If challenged by HMRC, the contractor can use this reference to confirm the date and outcome of the verification.

The confirmed deduction rate — 0% (gross), 20% (net/standard), or 30% (higher/unverified) — must be stated. The deduction rate confirmed at verification governs all subsequent payments to that subcontractor until re-verification is required. Applying the wrong deduction rate — whether by applying 20% when HMRC confirmed 30%, or by failing to deduct at all without gross payment status — can result in the contractor becoming personally liable for the unpaid tax under regulation 13 of the Income Tax (Construction Industry Scheme) Regulations 2005.

The verification date and method section records when the verification was completed and whether it was carried out online, by telephone, or through payroll software. This information is useful for resolving any discrepancy between the contractor's records and HMRC's CIS database.

The authorised signatory block should identify the person within the contractor's organisation who completed the verification, confirming personal responsibility for the accuracy of the record. For larger contractors with multiple site managers, this attribution helps identify who to contact if HMRC raises a query about a specific subcontractor payment.
