Domestic reverse charge VAT in construction: the complete guide

What is the domestic reverse charge for construction?

The domestic reverse charge (DRC) is a VAT accounting mechanism that shifts the responsibility for reporting and paying VAT from the supplier to the customer. In a standard VAT transaction, the supplier charges VAT and pays it to HMRC. Under the reverse charge, the customer accounts for VAT on their own return rather than paying it to the supplier.

The reverse charge was introduced in the construction sector in March 2021 primarily to combat VAT fraud — specifically missing trader fraud where subcontractors would charge VAT to customers, collect the money, and then disappear before paying it to HMRC. By shifting the accounting responsibility to the customer, HMRC removed the opportunity for this type of fraud.

When does the construction reverse charge apply?

The domestic reverse charge applies when all four of the following conditions are met:

1. The supply is of construction services (or goods alongside construction services)
2. The supply is subject to VAT at the standard rate (20%) or reduced rate (5%)
3. Both the supplier and customer are VAT registered
4. The customer is not the end user (i.e. the customer will use the services as part of their own construction business rather than as the final consumer of the building)

All four conditions must be satisfied. If any one of them is not met, the reverse charge does not apply and the standard VAT rules apply instead.

When does the reverse charge NOT apply?

This is where many bookkeepers and contractors go wrong. The reverse charge does not apply in the following situations:

• End users — if the customer is the final user of the building (a business that occupies the property or a homeowner), the reverse charge does not apply. The subcontractor charges standard VAT.
• Intermediary suppliers — a supplier who is connected to or in a group with the customer, and sells the services on without making a margin, can be treated as an end user.
• Zero-rated work — construction of new residential properties, certain conversions, and other zero-rated construction supplies are not subject to reverse charge because there is no VAT to account for.
• Non-VAT-registered customers — if the customer is not VAT registered, standard VAT applies.
• Non-construction supplies — scaffolding hire, plant hire, and delivery of materials without labour are generally outside the scope of CIS and DRC.

How to account for the reverse charge — the supplier

If you are the subcontractor supplying services subject to the reverse charge:

• Issue an invoice showing the net value of your services
• Do not add VAT to the invoice
• Add a note on the invoice stating the reverse charge applies, for example: "Reverse charge: customer to account for VAT at 20% — £X"
• On your VAT return, include the net sale value in Box 6 (total value of sales) but do not include any output tax in Box 1

Your VAT return will show lower output tax than normal. If you regularly claim input tax on materials and equipment, you may find yourself in a VAT repayment position more often. You can request monthly VAT returns from HMRC to improve your cash flow in this situation.

How to account for the reverse charge — the customer

If you are the contractor receiving services subject to the reverse charge:

• You receive an invoice without VAT
• You calculate the VAT yourself (20% of the net value)
• On your VAT return: include the VAT amount in Box 1 (output tax) AND in Box 4 (input tax) simultaneously
• Include the net value in Box 6 (total sales) and Box 7 (total purchases)

Because you are accounting for the VAT as both output and input simultaneously, the net cash effect on your VAT return is typically nil — which is the point. The VAT is declared and reclaimed in the same period without any cash actually changing hands for the VAT element.

Common reverse charge mistakes

Mistake 1: Subcontractor charges standard VAT when reverse charge should apply

The subcontractor issues an invoice with 20% VAT added. The contractor pays the invoice including VAT. The subcontractor includes the output tax on their return. The contractor includes it as input tax on theirs. Both returns balance — but both are wrong. HMRC may assess the customer for the full reverse charge amount as if it had never been accounted for, even though VAT was collected and paid.

Mistake 2: Contractor doesn't account for reverse charge on their return

The contractor receives a correct reverse charge invoice (no VAT charged), recognises it correctly in their books, but then fails to include the reverse charge VAT in Boxes 1 and 4 of their return. This results in understated output tax and potential underpayment penalties.

Mistake 3: Applying reverse charge to end users

A subcontractor working directly for a homeowner or occupying business applies reverse charge. The customer is the end user — standard VAT should apply. The subcontractor should have charged 20% VAT but didn't, leaving them out of pocket for VAT that HMRC will still expect to be accounted for.

Correcting past reverse charge errors

If you have been applying reverse charge incorrectly — either by charging VAT when you shouldn't have, or failing to account for it when you should — the correction process depends on the size of the error and when it occurred.

Errors under £10,000 net can usually be corrected on the next VAT return. Larger errors, or errors that HMRC might view as deliberate, should be disclosed separately using form VAT652. For significant or historic errors, taking advice from a qualified accountant before attempting to correct is strongly recommended.

How bookd. handles reverse charge VAT

The domestic reverse charge is one of the most complex areas of VAT treatment for construction businesses and their bookkeepers. bookd. applies the correct VAT treatment to every construction invoice as a standard part of our processing workflow — identifying whether DRC, standard VAT, or zero rating applies based on the nature of the supply, the registration status of both parties, and the end-user question.

For accounting firms with construction clients, this specialist knowledge is included in the bookd. white label service. Your clients get correct VAT treatment on every transaction. You get a clean, review-ready return.
