The construction sector has lived with the VAT Domestic Reverse Charge (DRC) since March 2021, but lately, HMRC’s attitude towards compliance has changed dramatically.

What began as a regime introduced to combat VAT fraud, with a promise of “light‑touch” enforcement, is now an area where HMRC teams are actively identifying errors, issuing assessments, and applying penalties with increasing confidence.

Many honest contractors and subcontractors are still grappling with the rules, and HMRC has clearly run out of patience. For businesses operating anywhere in the construction supply chain, now is the moment to get DRC compliance in order.

So, what exactly is the VAT Domestic Reverse Charge? In short, the DRC shifts the VAT accounting obligation from the supplier, typically the subcontractor, to the customer, typically the contractor, but only where certain conditions are met.

Under the DRC the subcontractor invoices without VAT, reporting only the net sale. The contractor accounts for VAT on their own VAT return, both the output and input VAT, and records the net purchase as normal. This mechanism was introduced as an anti‑fraud measure within supply chains considered high‑risk by HMRC.

The DRC applies when all the following conditions are satisfied:

• Supplier and customer are UK VAT‑registered
• The supply is standard‑rated or reduced‑rated
• The work is within the Construction Industry Scheme (CIS)
• The customer is registered for CIS
• The customer has not confirmed they are an end user
• The customer has not confirmed they are an intermediary supplier

It applies widely to supplies classified as “construction operations” for CIS purposes, including alteration, repair, extension, demolition and installation works, and includes goods supplied as part of those services.

It’s useful to know when the DRC does not apply, namely:

• The customer is not VAT‑registered or not CIS‑registered
• The customer has formally declared they are an end user or intermediary supplier
• The supply is zero‑rated, e.g. new‑build housing
• The supply is between connected landlords and tenants or group companies, where the correct notifications are in place

Everyone agrees that DRC is a challenge. Even businesses acting in good faith continue to struggle with implementation.

Common issues include:

• Misinterpreting the rules
• Assuming the “other party” will determine the correct VAT treatment
• Missing key details such as end‑user notifications
• Incorrect invoicing that fails to flag the application of the DRC
• Suppliers knowingly charging incorrect VAT to boost short‑term cash flow 

These errors cause disputes, payment delays, poor cash forecasting and, increasingly, HMRC intervention.

Over the last few years, I’ve helped contractors and subcontractors with the following: resolve disputes; set up robust DRC controls; deliver team training; and challenge unfair HMRC assessments. Here are some practical issues we see daily followed by some tips to help navigate the DRC minefield.

1. Late Payments Caused by VAT Disputes

Uncertainty around whether the DRC applies can lead to invoice disputes, and contractors may refuse to pay until the VAT treatment is resolved.

This is particularly common where:

• CIS status is unclear
• End‑user notifications are missing
• Parties have made differing assumptions about the same service

The effect on cash flow is immediate and painful.

2. HMRC Is Actively Enforcing DRC Compliance

HMRC has moved far beyond its gentle, educational approach.

We are seeing:

• More enquiries targeting errors in reverse charge accounting
• Assessments where VAT has been incorrectly charged
• Penalties and interest where systems or processes are inadequate 

Worryingly, HMRC’s public webinars have not been updated to reflect this change, they still cover introductory points, while compliance teams on the ground are taking a far stricter stance.

It is essential that businesses have robust systems, accurate records and the ability to demonstrate correct decision‑making.

3. CIS Classification Confusion

A recurring issue is uncertainty over whether an activity qualifies as a “construction operation” for CIS. For example:

• Businesses assume an activity is within CIS when HMRC views it as marginal or outside scope
• Activities are mis‑classified because the terms used in the contract do not reflect the actual work

Getting CIS classification wrong often means getting the VAT wrong too.

4. Cash Flow Crunch for Subcontractors

Under the DRC, subcontractors no longer receive VAT from customers, removing a buffer many relied on for working capital. Some still feel the shock several years on. Accurate DRC application is key to realistic cash flow forecasting.

5. Missing End‑User or Intermediary Supplier Notifications

End users and intermediary suppliers must confirm their status in writing. Without this:

• Suppliers must apply the DRC
• Customers risk incorrect VAT reporting and HMRC disputes

A simple written declaration is enough, no complex contracts required, but record‑keeping must be watertight.

6. Mixed Supplies and the 5% Rule

Where a supply contains both DRC and non‑DRC elements, the default is that the entire supply is subject to the DRC. The only exception is if the DRC element is 5% or less of the total value and both parties agree otherwise.

Documenting the rationale is essential.

7. Invoicing and Accounting Systems

Invoices must clearly state that the DRC applies and show the applicable VAT rate or amount.

System limitations often create risk, including:

• Software that cannot flag DRC services
• Staff issuing standard VAT invoices to “get things out the door”
• Inconsistent wording in templates

These errors attract HMRC attention.

8. Labour‑Only Subcontractors vs Employment Businesses

The DRC applies to labour‑only subcontractors where the subcontractor is responsible for the work and its outcome. It does not apply to employment businesses supplying staff. The distinction depends on substance, not labels, and misclassifications are common.

Tips for Navigating the DRC

• Check customers’ VAT and CIS status before invoicing
• Get written confirmation of end‑user or intermediary status
• Train staff on when the DRC applies
• Update contracts and terms to include DRC obligations
• Review subcontractor cash‑flow forecasts
• Maintain clear records for audit and HMRC enquiries
• Get advice early – DRC issues escalate quickly if left unresolved

In summary, the VAT Domestic Reverse Charge is now embedded in the construction sector and HMRC is clearly determined to enforce it.

While the rules aim to prevent fraud, they create real‑world challenges for compliant businesses. The best protection is clear communication, strong processes, and a willingness to seek proven professional guidance where needed.
