The VAT reverse charge moves the job of accounting for VAT from the seller to the buyer. It applies in three main situations: construction services reported under the Construction Industry Scheme (CIS), certain specified goods such as mobile phones and computer chips, and services bought from overseas suppliers. Each situation has its own rules, invoice requirements, and VAT return entries, and they are not interchangeable. The mistakes that cause the most trouble are wrong invoice wording, wrong return boxes, and mishandled end-user cases, and a few simple checks catch most of them.
- Under the VAT reverse charge, the customer accounts for the VAT, not the supplier.
- The domestic reverse charge for construction applies between VAT-registered businesses for CIS services, unless the customer is an end user or intermediary supplier who has told the supplier so in writing.
- Invoices must include the reference “reverse charge”, and the VAT is not added to the amount charged.
- Return entries differ between domestic construction and overseas services, particularly in Box 6.
- Construction reverse charge supplies cannot go through the Cash Accounting Scheme, and they are excluded from the flat rate scheme calculation.
The reverse charge is easy to explain and surprisingly easy to get wrong. A subcontractor adds VAT when they shouldn’t. A contractor forgets to record the VAT on their own return. A business buys software from a company abroad and never accounts for the UK VAT. Each error looks small, but together they can leave a VAT return wrong and prompt questions from HMRC.
In this guide, we explain how the VAT reverse charge works, where it applies, what your invoices must say, how to complete your return, and which mistakes to watch for. We also describe the checks we carry out for clients at CartWheel International, so you can see how we catch errors before filing a return.
What Is the VAT Reverse Charge?
Normally, a VAT-registered seller adds VAT to their invoice, collects it from the customer and pays it to HMRC. The customer then reclaims it as input tax if they are entitled to. Under the reverse charge, the seller does not add VAT. Instead, the customer records both the VAT due and the VAT reclaimable on their own VAT return.
This is often called self-accounting VAT. For a business that can recover all of its VAT, the two entries cancel out, and no money changes hands. If a business cannot recover all of its input VAT, for example because of partial exemption, the VAT it has to account for can become a real cost.
The reasons differ by type. The domestic reverse charge, for construction and certain specified goods, is an anti-fraud measure. The overseas-services reverse charge makes the UK customer responsible for accounting for UK VAT on qualifying services bought from suppliers who are based abroad. Keep the two separate in your mind, because the invoice wording, the return boxes, and the scheme rules are not the same.
When Does Reverse Charge VAT Apply?
The reverse charge covers three situations, and each has different conditions.
The domestic reverse charge for construction services
This is the one most small businesses meet. It applies to many building and construction services, and it came into force on 1 March 2021. HMRC sets out the conditions in its guidance on when you must use the domestic reverse charge for building and construction services. The reverse charge applies when both the supplier and customer are VAT-registered in the UK, the services are standard- or reduced-rated, and payment is reported under the Construction Industry Scheme. It does not apply if the customer has validly told the supplier in writing that they are an end user or intermediary supplier.
Specified goods and services
A second set of domestic rules covers certain goods and services between UK businesses, including mobile phones and computer chips. For these goods, the reverse charge generally applies where the combined VAT-exclusive value of the qualifying items on an invoice reaches £5,000. Other items on the same invoice do not automatically count towards that figure, and rules apply to linked invoices and artificial splitting. HMRC covers these rules in VAT Notice 735.
Services from overseas suppliers
This is the cross-border B2B VAT rule. In general, business-to-business services are treated as supplied where the customer belongs, which for a UK business means the UK, although exceptions apply. Where the overseas-services reverse charge applies, the supplier does not charge UK VAT and the UK customer accounts for it. Before you decide, work out the place of supply, where the supplier and customer belong, and whether an exemption or special rule applies. HMRC explains this in VAT Notice 741A. An overseas supplier holding a UK VAT number does not, by itself, stop the reverse charge from applying.

Does the CIS Reverse Charge Apply to Sub-contractors?
The CIS reverse charge applies to most sub-contractors who supply construction services to a VAT-registered contractor, because those services fall within the Construction Industry Scheme. It covers the whole supply, including materials supplied as part of the job, not just the labour. If you are unsure whether you are a contractor or sub-contractor, read HMRC’s CIS 340 guide.
There is one important distinction. Employment businesses that provide workers are treated as supplying staff, not construction services, so they sit outside the reverse charge. A labour-only sub-contractor who agrees a price for specified work and is responsible for it sits inside the reverse charge. HMRC’s technical guide lists the characteristics that separate the two, and it is worth checking before you invoice, because the VAT treatment is completely different.
What is an end user, and why does it matter?
An end user is a VAT- and CIS-registered business that does not make onward supplies of the construction services it receives. If your customer is an end user and tells you so in writing, the reverse charge does not apply, and you charge VAT in the normal way. Being an end user is optional, and the customer must notify the supplier to stop applying the reverse charge.
If you are the supplier and the customer has not confirmed their status in writing, HMRC guidance is that you should still apply the reverse charge where the customer is VAT- and CIS-registered. If an end-user notification is not made correctly, the customer becomes liable for accounting for the VAT that should have been charged. That is why we recommend keeping written confirmations on file.
What is an intermediary supplier?
An intermediary supplier is a VAT- and CIS-registered business that buys construction services and re-supplies them, without material alteration, to a connected or linked end user. The connection must satisfy HMRC’s conditions, which depend on a shared relevant interest in the land, such as a landlord and tenant, or on being part of the same corporate group. The exclusion applies once the supplier receives written notification. Being connected to an end user is not enough on its own.
What Does a Reverse Charge Invoice Need to Say?
Treat a reverse charge invoice as a standard VAT invoice with a few extra requirements. The words “reverse charge” must appear on it, as HMRC requires, and it should show that your customer will be accounting for the VAT under the reverse charge and that your customer, not you, has to account for the VAT. Leave the VAT out of the sum your customer owes you. Instead, state the amount of VAT due under the reverse charge, or the applicable rate if the amount cannot be shown.
The safest wording puts “reverse charge” at the start, for example “Reverse charge: customer to account for VAT to HMRC”. HMRC also accepts wording that cites the legislation, such as “Reverse charge: VAT Act 1994 Section 55A applies”. If your accounting software cannot display the VAT amount, add wording to say the customer has to account to HMRC, and make sure the customer can tell which items are subject to the reverse charge.
How Do You Account for the Reverse Charge? An Example
Here is a simple reverse charge VAT example. A sub-contractor completes a job for a contractor and agrees a price of £10,000 for labour and materials. The services are standard rated at 20%, so the VAT under the reverse charge is £2,000.
The sub-contractor issues an invoice for £10,000 with no VAT added and the reverse charge wording. The contractor then records the £10,000 as a cost, the £2,000 as VAT due on their return, and the same £2,000 as input VAT to be reclaimed, assuming they are entitled to recover it. These are the accounting entries for the transaction.
The return entries depend on which reverse charge applies. These figures are for this one transaction, not for the whole return:
Situation | Box 1 | Box 4 | Box 6 | Box 7 |
Construction supplier | No output VAT | Not applicable | £10,000 | Not applicable |
Construction customer | £2,000 | £2,000 | Do not include | £10,000 |
UK customer buying overseas services | £2,000 | £2,000 | £10,000 | £10,000 |
The supplier enters only the net sale value. The construction customer enters the VAT due and the VAT reclaimed, plus the net purchase value in Box 7, but does not treat the purchase as a net sale. A UK customer buying qualifying overseas services enters the net value in both Box 6 and Box 7. HMRC explains the construction entries in its technical guide, and its guidance for buyers of construction services walks through the customer’s side.
How Does Reverse Charge VAT Work on Imported Services?
When you buy qualifying services from an overseas supplier, you account for the UK VAT yourself. Enter the VAT in Box 1 and, if you are entitled to reclaim it, in Box 4; enter the net value in Boxes 6 and 7. As above, first establish the place of supply and check for exemptions or special rules in VAT Notice 741A.
If you are not VAT registered, do not ignore overseas service purchases. The value of general-rule B2B services you receive from overseas suppliers counts towards your VAT registration assessment, even if you make no taxable supplies yourself. HMRC sets this out in its manual on reverse charge registration.
People sometimes confuse this with postponed VAT accounting. That is a separate mechanism, which lets VAT-registered importers declare and reclaim import VAT on goods on the same VAT return, instead of paying it at the border. It works similarly, but it applies to goods coming into the UK, not services bought from overseas.
How Do VAT Schemes Affect the Construction Reverse Charge?
Several VAT schemes interact with the construction reverse charge in ways that catch businesses out. The points below come from HMRC’s construction guidance, so do not assume they apply in the same way to every other type of reverse charge.
Cash Accounting Scheme
Supplies that fall under the construction reverse charge, whether you are buying or selling them, cannot be put through the VAT Cash Accounting Scheme. Everything else in your business can stay on the scheme as normal.
Reverse charge VAT and the flat rate scheme
Construction reverse charge supplies are not accounted for under the flat rate scheme. If you are on the scheme and buy construction services under the reverse charge, you account for the VAT due and reclaim it on the same return. If you make reverse charge supplies, you exclude their value from your flat rate calculation. Because flat rate users cannot normally reclaim VAT on materials and overheads, it is worth checking whether the scheme still suits you.
Cash flow and monthly returns
When your customers stop paying you VAT, your returns may turn into repayments, and your cash flow may change. HMRC’s guidance notes that you can apply to move to monthly returns through your online VAT account. Whatever accounting software you use, check that it has reverse charge VAT codes and can print the correct wording on your invoices.
What Mistakes Lead to Reverse Charge VAT Penalties?
When HMRC introduced the construction reverse charge, it said it would take a light-touch approach to errors during the first six months. That period ended long ago, so ordinary VAT rules on errors now apply. HMRC also reminds businesses to correct mistakes as soon as they find them.
These are the mistakes that commonly cause problems with the reverse charge:
- Charging VAT on an invoice when the reverse charge applies, or not charging it when it does not.
- Leaving the “reverse charge” reference off the invoice.
- Failing to enter the VAT in both Box 1 and Box 4.
- Using the wrong Box 6 treatment, which differs between construction purchases and overseas services.
- Applying the reverse charge to a customer who has validly notified end-user status, or ignoring a badly worded notification.
- Treating an employment business as a construction sub-contractor, or the reverse.
- Missing the VAT due on services bought from overseas suppliers, or missing a registration obligation.
If a supplier wrongly charges VAT on a supply that falls under the construction reverse charge, the customer should ask for a corrected invoice, not reclaim that VAT as though it had been correctly charged.
Reverse charge errors can require invoice corrections and VAT return adjustments. Interest and penalties depend on the circumstances, including whether there is a VAT shortfall and whether the error was careless or deliberate. HMRC does not charge an inaccuracy penalty when you took reasonable care. Missing a filing deadline is a separate matter, covered by the late submission points system.
How Does CartWheel International Help You Avoid Reverse Charge Errors?
We cannot promise that HMRC will never raise a query or charge a penalty, and no accountant can honestly promise that. What we can do is put checks in place so that errors are far less likely to reach your return. CartWheel International is a London accounting firm, and reverse charge questions are a regular part of the VAT work we review with clients.
For each type of sale and purchase, we check whether the reverse charge applies, including end-user and intermediary cases, and we keep written confirmations with your records. We review how your invoices and accounting software handle the wording and VAT codes, and we check your return entries prior to submission, including the Box 6 and Box 7 treatment. If your cash flow changes, we assess whether monthly returns would help, and for businesses buying from overseas, we check whether any registration obligation could be triggered.
Frequently Asked Questions
Ask them for a corrected invoice without VAT. Do not reclaim the VAT as though it had been charged correctly. Instead, account for the VAT on your own return under the reverse charge.
No. It applies when both parties are VAT-registered in the UK, the services are standard or reduced rated and within the Construction Industry Scheme, and the customer has not validly notified that they are an end user or intermediary supplier. Employment businesses supplying workers are outside it.
For domestic construction purchases, enter the VAT due in Box 1, any recoverable input VAT in Box 4, and the net purchase value in Box 7, not Box 6. The supplier enters the net sale in Box 6 with no output VAT in Box 1. For qualifying services from overseas suppliers, the customer enters the VAT in Boxes 1 and 4 and the net value in Boxes 6 and 7.
The reverse charge applies to certain services (and specified goods) where the customer accounts for the VAT. Postponed VAT accounting applies to goods imported into the UK, letting VAT-registered importers declare and reclaim import VAT on their return instead of paying it at the border.
