The United Kingdom VAT domestic reverse charge for most building and construction services moved the obligation to account for output VAT from the supplier to the VAT-registered business customer when statutory conditions are met, including that the supply is within the Construction Industry Scheme and both parties are VAT registered in the United Kingdom, with further tests for rates, end users, and intermediary suppliers. HMRC treats the measure as an anti-fraud domestic reverse charge that sits alongside wider domestic reverse charge rules in VAT Notice 735. Suppliers must not charge VAT to the customer in the usual way when the reverse charge applies, and must instead use compliant invoice wording while the customer accounts for VAT on their VAT Return. Written end user or intermediary supplier notifications switch specific chains back to normal VAT charging when the law allows.
This guide summarises public GOV.UK and HMRC guidance. It is practical commentary only and is not tax or legal advice. Confirm your facts with HMRC or a qualified United Kingdom tax adviser.
Context
Ordinary VAT invoices show output VAT collected by the supplier. Under the construction domestic reverse charge, the supplier still issues a VAT invoice style document, but the customer self-accounts for the VAT due while the supplier omits that VAT from the cash amount charged when the rules apply. CIS registration status, written customer notifications, and employment business rules decide whether you sit in that treatment.
VAT Notice 735 explains that the VAT domestic reverse charge procedure is an anti-fraud measure designed to counter criminal attacks on the United Kingdom VAT system by means of sophisticated fraud, and lists construction services as a specified service with effect from 1 March 2021 with a cross-link to building and construction guidance (HM Revenue and Customs, VAT Notice 735: Domestic reverse charge procedure).
HMRC’s technical guide states that if you are an end user you are a business, or group of businesses, that are VAT and Construction Industry Scheme registered and do not make onward supplies of the building and construction services that you receive, and that building contractors are not usually end users because they make onward supplies of construction services (HM Revenue and Customs, VAT domestic reverse charge technical guide).
The same technical guide explains that the reverse charge does not apply for supplies to end users when the end user tells their supplier or building contractor in writing that they are an end user, and that being an end user is optional but the customer must tell the supplier in writing before the supplier may stop applying the reverse charge and charge VAT under normal rules (HM Revenue and Customs, VAT domestic reverse charge technical guide).
HMRC states that if you are a supplier, and you believe your customer is an end user but they have not notified you in writing, you should still apply the reverse charge rather than charge VAT under normal rules if the customer is VAT and Construction Industry Scheme registered and the other conditions are met (HM Revenue and Customs, VAT domestic reverse charge technical guide).
Brian Berry, Chief Executive of the Federation of Master Builders, said in February 2021 that reverse charge VAT is a damaging policy being introduced at the worst possible time for builders, and that by removing the flow of VAT money between businesses in the construction supply chain, four in ten builders say this will have a significant or moderate impact on their cashflow (Federation of Master Builders, press release, 16 February 2021).

HMRC’s technical guide states that when supplying a service subject to the domestic reverse charge, suppliers must show all the information required on a VAT invoice, make a note that the domestic reverse charge applies and that the customer is required to account for the VAT, and clearly state how much VAT is due under the reverse charge, or state the rate of VAT, but not include the VAT in the amount charged to the customer (HM Revenue and Customs, VAT domestic reverse charge technical guide).

In February 2021 the Federation of Master Builders reported survey data where 66 percent of builders either anticipated moderate or significant cash flow impact from reverse charge VAT, were still unclear on the details of the policy, or had never heard of it (Federation of Master Builders, press release, 16 February 2021).

Workflow
Start with customer status, then contract and CIS facts, then invoice wording, then VAT Return lines. Keep evidence of written notifications with the job file so an audit can follow the same story your accounts tell.
HMRC expects you to ask customers whether they are registered for VAT and Construction Industry Scheme where sales operations are not clearly domestic consumer only, and the technical guide explains that end user notifications remove the need to keep re-checking those facts once valid written notice exists (HM Revenue and Customs, VAT domestic reverse charge technical guide).
Work through HMRC’s “check when you must use the VAT reverse charge for building and construction services” guidance together with VAT Notice 735 so you do not treat excluded supplies, such as many employment business supplies of staff, as if they were reverse charge construction services (HM Revenue and Customs, VAT Notice 735, and GOV.UK building and construction reverse charge guidance).
Tip: CIS 340 still helps you see whether you are a contractor or subcontractor for Construction Industry Scheme purposes, which feeds the VAT tests (HM Revenue and Customs, CIS 340).
HMRC allows email, post, or contract wording, and publishes example notification text referencing section 55A of the VAT Act 1994. Intermediary suppliers may refer to themselves as end users when notifying suppliers. Keep the notification with the contract so everyone knows which supplies it covers (HM Revenue and Customs, VAT domestic reverse charge technical guide).
Follow HMRC’s invoice checklist: full VAT invoice fields, a clear domestic reverse charge statement, the amount of VAT due or at least the rate, and no VAT included in the cash total charged to the customer. The VAT regulations require the reference “reverse charge” on invoices for services subject to the reverse charge (HM Revenue and Customs, VAT domestic reverse charge technical guide).
HMRC explains that suppliers enter only the net sale on the VAT Return for reverse charge sales, while customers add reverse charge VAT to output tax and reclaim input tax under normal rules on the same return. If goods and construction services form a single supply, the reverse charge usually applies to the full invoice value subject to stated disregards (HM Revenue and Customs, VAT domestic reverse charge technical guide).
HMRC states that you cannot use the VAT Cash Accounting Scheme for supplies you buy or sell that are subject to the reverse charge, and sets out extra steps for Flat Rate Scheme users who make or receive reverse charge supplies (HM Revenue and Customs, VAT domestic reverse charge technical guide).
Checklists
Use these lists on bid acceptance, first application for payment, and month-end VAT preparation so CIS and VAT stories stay aligned.
Pitfalls
Errors cluster around treating quiet customers as end users without paper proof, splitting supply and fix invoices to dodge reverse charge, or forgetting scheme restrictions.
Problem
HMRC is explicit that suppliers should still apply the reverse charge when a customer might be an end user but has not confirmed that in writing.
Fix
Request written notification using HMRC example wording, file it with the job, and only then move to normal VAT charging.
Problem
HMRC warns that if a customer places a single supply and fix order within CIS and the supplier issues separate invoices, the reverse charge still applies to the full order value.
Fix
Price and document the transaction as HMRC views the supply, not as separate narratives that contradict the contract.
Problem
HMRC worked examples show landlords and tenants may choose different paths, which confuses project accountants who expect one rule for the whole site.
Fix
Map the legal entities in your ledger, then apply notifications entity by entity rather than by job nickname.
Problem
HMRC blocks cash accounting for reverse charge supplies and adds flat rate adjustments that can erase the benefit of the scheme.
Fix
Model VAT Return lines before you renew scheme elections, especially if reverse charge purchases dominate your ledger.
Plain-language answers for subcontractors, main contractors, and finance staff who share United Kingdom construction ledgers.
It is a domestic reverse charge measure listed in VAT Notice 735 where specified construction services moved into the regime from 1 March 2021. When conditions are met, the customer accounts for output VAT to HMRC instead of paying that VAT to the supplier, while the supplier uses compliant invoice wording (HM Revenue and Customs, VAT Notice 735, and VAT domestic reverse charge technical guide).
HMRC’s technical guide gives the example that if services are provided to a private domestic customer, the reverse charge does not apply because the customer will not be VAT registered. That does not make the main contractor an end user for reverse charge purposes, so supplies to that contractor by subcontractors can still be subject to the reverse charge when other tests pass (HM Revenue and Customs, VAT domestic reverse charge technical guide).
HMRC requires the usual VAT invoice information plus wording that the domestic reverse charge applies and that the customer must account for the VAT, with the VAT amount or rate shown, but that VAT must not be included in the amount charged to the customer (HM Revenue and Customs, VAT domestic reverse charge technical guide).
HMRC lists examples such as “VAT Act 1994 Section 55A applies”, “S55A VATA 94 applies”, or “Customer to pay the VAT to HMRC”, and notes that regulations require the reference “reverse charge” on invoices for affected services (HM Revenue and Customs, VAT domestic reverse charge technical guide).
HMRC explains that being an end user is optional, but if the customer wants normal VAT invoices they must notify the supplier in writing. If they stay silent while VAT and Construction Industry Scheme tests are met, suppliers should still apply the reverse charge (HM Revenue and Customs, VAT domestic reverse charge technical guide).
HMRC states that if you buy services subject to the reverse charge you must add the VAT charged to the output tax total on your VAT Return, not as a net sale, and you may reclaim the input tax subject to normal rules (HM Revenue and Customs, VAT domestic reverse charge technical guide).
HMRC explains that suppliers must not enter output tax on reverse charge sales and should enter the net value of those sales (HM Revenue and Customs, VAT domestic reverse charge technical guide).
HMRC states that supplies by employment businesses are not subject to the reverse charge, even if those supplies are within Construction Industry Scheme, because employment businesses supplying construction workers are treated as supplying staff rather than building and construction services (HM Revenue and Customs, VAT domestic reverse charge technical guide).
HMRC draws a distinction: supplies by labour-only subcontractors can be subject to the reverse charge when Construction Industry Scheme and other conditions are met, while supplies of staff by employment businesses are not (HM Revenue and Customs, VAT domestic reverse charge technical guide).
HMRC describes cases where a customer predominantly acts as an end user but re-supplies a very small share of services, and explains a five percent disregard that can still allow an end user declaration. A separate five percent disregard can apply where only a minor element of a mixed supply would fall under reverse charge (HM Revenue and Customs, VAT domestic reverse charge technical guide).
Start with VAT Notice 735 for the domestic reverse charge framework, HMRC’s building and construction service checklist on GOV.UK, and the VAT domestic reverse charge technical guide for scenarios, invoice examples, and VAT Return commentary (HM Revenue and Customs).
