When does a VAT reverse charge apply?

VAT reverse charge is a VAT accounting rule that makes you, the buyer, responsible for declaring and remitting the tax to HMRC instead of your supplier. Your supplier invoices you for the net amount, and you account for the VAT directly on your VAT return.

The reverse charge covers several types of UK transactions, including construction services under the Construction Industry Scheme (CIS), cross-border B2B purchases, and certain high-risk goods.

What does VAT reverse charge mean?

Under normal VAT rules, your supplier charges VAT and remits it to HMRC. The reverse charge shifts that responsibility to you as the buyer.

HMRC introduced this as an anti-fraud measure. In industries prone to missing-trader fraud, suppliers would charge VAT, collect the payment, and disappear without remitting the tax. Because you account for the VAT directly, there's no opportunity for a supplier to collect and leave.

The reverse charge doesn't change how much VAT you owe on a transaction, only who reports it. As the buyer, you declare the VAT as output tax and, if you're fully VAT-recoverable, reclaim the same amount as input tax on the same return.

How does the VAT reverse charge work in practice?

Your supplier sends an invoice without VAT, you record the tax on your own return, and if you're fully recoverable, the amounts cancel out to zero.

What your supplier's invoice should include

When the reverse charge applies, your supplier sends an invoice showing the net amount without adding VAT. The invoice must include a note stating that the reverse charge applies. For construction, acceptable wording includes "customer to account to HMRC for the reverse charge" or a reference to section 55A of the VAT Act 1994.

Even though your supplier isn't collecting the tax, the invoice should still show the applicable VAT rate and the amount of VAT due. If you receive an invoice that includes VAT as a line item, don't pay the VAT portion and ask your supplier to reissue with the correct reverse-charge notation.

How to record it on your VAT return

You record the reverse charge in two places on your return. Include the VAT amount as output tax in Box 1, then claim the same amount as input tax in Box 4, provided you're entitled to full VAT recovery.

The net purchase value goes in Box 7. For cross-border purchases, include the value in Box 6 as well.

Because you're declaring and reclaiming the same figure, the VAT nets to zero on your return.

The net cash effect for your business

If you're fully VAT-recoverable, the reverse charge has zero cash impact. The output tax and input tax cancel out on the same return.

That changes if you have partial exemption. You still declare the full output tax, but you can only reclaim the portion your recovery rate allows. The difference becomes a genuine VAT liability on that return.

When does the VAT reverse charge apply?

Construction services under CIS

The VAT domestic reverse charge for construction applies to building and construction services between VAT-registered, CIS-registered businesses. It covers most physical construction work, including building, repairs, and demolition.

Not every construction invoice triggers the reverse charge. If you supply services directly to an end user who won't make an onward supply of construction services, you charge standard VAT instead.

Professional services like architecture and surveying also fall outside the scope. Confirming your customer's end-user status in writing before invoicing reduces misclassification risk.

Cross-border B2B services

When you buy services from a supplier based outside the UK, you typically account for VAT using the reverse charge. This applies to most B2B services where the place of supply falls in the UK under the general rule, covering consulting, legal work, and software subscriptions from overseas providers.

Without the reverse charge, your overseas supplier would need to register for UK VAT. Instead, you report the VAT on your return, keeping the compliance burden where HMRC can monitor it.

Wholesale and high-risk goods

HMRC also applies the reverse charge to specific categories of goods with a history of missing-trader fraud. These include wholesale supplies of gas and electricity, emissions allowances, and mobile phones or computer chips with a VAT-exclusive invoice value of £5,000 or more.

If you trade in any of these goods at wholesale volumes, check HMRC's current list of specified supplies. Thresholds and qualifying categories change periodically.

Where do finance teams get the VAT reverse charge wrong?

Charging VAT when the reverse charge should apply

This is a common error in construction. A subcontractor charges standard VAT on an invoice that should have used the reverse charge, the contractor pays it, and both VAT returns contain errors.

If you're the supplier, confirm whether your customer qualifies as an end user before adding VAT. If you're the buyer, review incoming invoices against your accounts payable records to verify the reverse charge has been applied correctly.

Missing the required invoice wording

HMRC requires specific notation on reverse-charge invoices. Leaving it off doesn't change the underlying tax treatment, but it creates an audit trail gap. HMRC may require you to justify the reverse-charge treatment and ask your supplier to reissue.

Reporting in the wrong boxes on your VAT return

The reverse charge requires entries in multiple boxes on your return. Putting the amount in the wrong box, or forgetting the input tax reclaim in Box 4, creates errors on your return and can trigger queries from HMRC.

If you process reverse-charge transactions regularly, a checklist in your invoice processing workflow helps keep the entries consistent.

Overlooking the end-user test in construction

The construction reverse charge doesn't apply when you supply services to an end user, but "end user" has a specific VAT definition. It means a customer who won't make an onward supply of the construction services they're receiving.

A main contractor who subcontracts work and passes construction services along a supply chain is not an end user. A business commissioning a fit-out of their own office space usually qualifies, because it's not making an onward supply of construction services. If you're unsure, asking your customer to confirm their status before invoicing helps avoid misclassification.

How to handle VAT reverse charge transactions step by step

1. Confirm both parties' VAT registration

The reverse charge only applies between VAT-registered businesses. Before applying it, verify that both you and your trading partner hold valid VAT registration.

For construction transactions, confirm CIS registration as well. You can check VAT numbers through HMRC's online verification service.

2. Determine whether the supply qualifies

Check the supply against the relevant reverse-charge category. For construction, confirm the work falls within CIS scope and that your customer isn't an end user.

For cross-border services, confirm the place of supply falls in the UK under the general B2B rule. For specified goods, check the transaction value against the relevant threshold.

3. Issue or request the correct invoice

If you're the supplier, invoice for the net amount and include the required reverse-charge notation along with the VAT rate and amount due. If you're the buyer, review incoming invoices to confirm the reverse-charge wording is present and that your supplier hasn't charged VAT incorrectly. Any discrepancies are worth resolving before processing the payment.

4. Record the transaction correctly on your VAT return

Declare the VAT as output tax in Box 1 and reclaim it as input tax in Box 4 on the same return. If you have partial exemption, apply your recovery rate to the input tax amount. A clear record of which transactions used the reverse charge supports the return if HMRC asks questions.

5. Review your processes each quarter

Reverse-charge rules and your trading relationships change over time. Review your partner lists each quarter and update your procurement workflows and accounting templates when HMRC publishes new guidance.
