HM Revenue & Customs is increasing scrutiny of VAT practices across the UK construction sector as part of a wider effort to tackle tax fraud and supply-chain abuse. Particular attention is now being given to the VAT reverse charge in the construction industry, with compliance teams actively reviewing how businesses apply the rules in subcontracting arrangements. Where errors are identified, HMRC is issuing assessments, penalties and compliance notices.
The tougher stance marks a shift from HMRC’s earlier “light-touch” approach following the introduction of the reverse charge rules in March 2021. At the same time, new powers announced in the Autumn Budget 2025 will come into force from April 2026, allowing HMRC to cancel companies’ Gross Payment Status and impose penalties on directors if they are linked to fraudulent supply chains.
The move reflects growing concern within government about organised tax evasion within construction, where complex subcontracting arrangements can make VAT fraud easier to conceal.
Key Points
- HMRC is increasing compliance checks on VAT reverse-charge rules in the construction industry.
- The VAT Domestic Reverse Charge shifts VAT accounting from subcontractors to contractors.
- Errors in applying the rules can lead to assessments, penalties and disputes.
- From April 2026, new powers will allow HMRC to cancel Gross Payment Status for companies linked to tax fraud.
- Directors may face penalties of up to 30% of the tax lost where fraud is identified.
- The reforms aim to reduce supply-chain fraud and protect compliant businesses.
What the VAT Reverse Charge in the Construction Industry Means for Contractors
The VAT Domestic Reverse Charge for building and construction services was introduced in March 2021 to reduce fraud in the industry. The mechanism transfers the responsibility for accounting for VAT from the supplier to the customer in certain transactions.
Instead of charging VAT, subcontractors invoice contractors without VAT and include wording confirming that the reverse charge applies. The contractor then accounts for both the output and input VAT on its own VAT return.
HMRC initially focused on helping businesses understand the new rules. However, the tax authority has now moved towards stricter enforcement as part of wider efforts to reduce the UK tax gap and strengthen VAT compliance for construction companies UK.
Compliance teams are reviewing transactions more closely and raising assessments where businesses incorrectly charge VAT or fail to apply the reverse charge.
Background and Context of VAT Reverse Charge in Construction Industry
The construction sector has historically been vulnerable to VAT fraud due to the complexity of subcontracting chains and the interaction of CIS and VAT rules for construction businesses.
One common fraud involves so-called “missing traders”. In these arrangements a supplier charges VAT but disappears before paying the tax to HMRC. The reverse charge mechanism removes this opportunity by shifting the VAT liability to the contractor receiving the services.
The reverse charge applies where:
- both parties are VAT-registered
- the supply falls within the Construction Industry Scheme (CIS)
- the services are standard-rated or reduced-rated for VAT
- the customer is not an end user or intermediary supplier
Certain transactions remain outside the rules, including zero-rated supplies such as new residential construction and work carried out for private homeowners.
Key Details and Upcoming Changes
Alongside stronger enforcement of existing VAT rules, the government is introducing new measures to combat supply-chain fraud within the Construction Industry Scheme.
Under legislation expected to take effect from 6 April 2026, HMRC will gain new powers to:
- Cancel Gross Payment Status immediately where a business knew or should have known it was involved in a fraudulent transaction
- Hold companies liable for lost tax resulting from fraudulent supply-chain arrangements
- Impose penalties of up to 30% of the lost tax on businesses and potentially their directors
- Prevent businesses from reapplying for Gross Payment Status for five years
These reforms were announced as part of the government’s wider strategy to close the tax gap and tackle organised financial crime within labour supply chains.
Who Is Affected
The increased enforcement will affect a wide range of participants in the construction sector, including:
- building contractors and subcontractors
- property developers
- labour-supply agencies
- umbrella payroll companies supplying workers to construction projects
- directors responsible for managing supply chains
Even businesses that operate legitimately may face greater scrutiny if they work with suppliers later found to be involved in tax fraud.
Expert Analysis: Apex Accountants Insight
The tightening of HMRC enforcement signals a significant shift in the tax authority’s approach to the construction industry.
For several years after the reverse charge was introduced, HMRC focused on educating businesses about the rules. That phase is now ending. The increased level of compliance activity suggests that HMRC believes most businesses should now be capable of applying the rules correctly.
This creates several practical risks for contractors and subcontractors.
Cash-flow pressures are one of the most immediate effects. Because subcontractors no longer collect VAT on invoices under the reverse charge, they lose a temporary working-capital advantage.
Administrative complexity is another challenge. Businesses must determine whether the reverse charge applies to each transaction and confirm the status of their customers.
The forthcoming CIS reforms also introduce a new level of risk for directors. The “knew or should have known” test means companies will be expected to perform meaningful due diligence on suppliers rather than relying on basic checks.
Why This Matters for UK Businesses
For construction firms, the consequences of non-compliance can be serious.
Potential impacts include:
- HMRC assessments and financial penalties
- loss of Gross Payment Status under CIS
- reduced cash flow due to CIS deductions
- supply-chain disputes and delayed payments
- reputational damage if linked to fraudulent operators
At the same time, stronger enforcement may benefit compliant businesses by reducing unfair competition from operators who evade tax.
Companies that maintain robust VAT procedures and carry out proper supply-chain checks will be better positioned to withstand increased scrutiny and strengthen VAT compliance for construction companies UK.
What Businesses Should Do
Construction businesses should consider the following steps to stay compliant with CIS and VAT rules for construction businesses:
- Review VAT procedures to ensure the reverse charge is applied correctly.
- Verify the VAT and CIS status of contractors and subcontractors.
- Obtain written confirmation where customers claim end-user or intermediary status.
- Update accounting systems so invoices clearly indicate when the reverse charge applies.
- Train finance and procurement teams on reverse-charge rules.
- Carry out supply-chain due diligence on labour providers and subcontractors.
- Seek professional advice if uncertain about VAT treatment.
Taking proactive steps now can reduce the risk of costly HMRC disputes later.
