Reverse charge VAT for construction: how to report it correctly on your VAT return

Reverse charge VAT can feel confusing when you first come across it, especially if you work in construction and already have CIS, invoices, subcontractors and VAT deadlines to think about.

The main point is simple. In certain construction transactions, the supplier does not charge VAT to the customer. Instead, the customer accounts for the VAT on their own VAT return. This is known as the domestic reverse charge for building and construction services.

If you get it wrong, your VAT return can be inaccurate, your invoices may be questioned, and HMRC may ask you to correct past returns. That is why it is important to understand when the reverse charge applies and how the figures should appear in the correct VAT return boxes.

If you are unsure, working with a VAT return accountant can help you avoid small reporting mistakes that later become bigger problems.

What is reverse charge VAT in construction?

Under normal VAT rules, you charge VAT on your invoice, collect it from your customer, and pay it over to HMRC through your VAT return.

With reverse charge VAT, that process changes. You still issue an invoice, but you do not add VAT to the amount payable. Your customer then accounts for the VAT on their own VAT return.

This usually applies where you are supplying construction services to another VAT-registered business that is also within the Construction Industry Scheme, and the services are standard-rated or reduced-rated. In the UK, that usually means 20% or 5% VAT.

For example, if you invoice a contractor £10,000 for qualifying construction work, you do not add £2,000 VAT to the invoice. Instead, the customer records the £2,000 VAT on their own VAT return.

When does the construction reverse charge apply?

The reverse charge is most likely to apply when:

• You are VAT registered in the UK.
• Your customer is VAT registered in the UK.
• The work falls within CIS.
• The supply would normally be charged at 20% or 5% VAT.
• Your customer has not told you in writing that they are an end user or intermediary supplier.

It often affects subcontractors working for main contractors. It does not usually apply to work for private domestic customers because they are not VAT registered. It also does not apply where the supply is zero-rated, such as certain new build work.

If your business is growing and your taxable turnover goes above the current UK VAT registration threshold of £90,000, you will need to be especially careful with VAT treatment from the point you register.

How should suppliers report reverse charge VAT?

If you are the supplier, your invoice must make it clear that the reverse charge applies. You should not charge VAT to your customer, but you should still show that VAT is being dealt with under the reverse charge rules.

Your invoice should include wording such as:

• “Reverse charge: customer to account for VAT to HMRC.”
• On your VAT return, you do not include output VAT for that sale in box 1. You only include the net value of the sale in box 6.
• So, if you issue a reverse charge invoice for £10,000:
• Box 1: £0 output VAT for that reverse charge sale
• Box 6: £10,000 net sale value

This is where mistakes often happen. Some businesses accidentally include VAT in box 1 even though they did not charge it. Others leave the sale out completely, which can make turnover figures look wrong.

If you want someone to check your return before submission, VAT accountants services can be useful, especially if you handle both normal VAT and reverse charge invoices.

How should customers report reverse charge VAT?

If you are the customer receiving a reverse charge invoice, you need to account for the VAT yourself.

Using the same £10,000 example at 20% VAT:

• Box 1: £2,000 output VAT
• Box 4: £2,000 input VAT, if you can reclaim it under normal VAT rules
• Box 7: £10,000 net purchase value
• Box 6: nothing for this purchase

For many fully taxable businesses, box 1 and box 4 cancel each other out, so there may be no extra VAT to pay on that transaction. However, it still needs to be reported correctly.

If your business is partly exempt, or you cannot reclaim all your input VAT, the position may be different. Do not automatically reclaim the full amount unless your business is entitled to do so.

Common reverse charge VAT return mistakes

One common mistake is treating a reverse charge invoice like a normal VAT invoice. If you are the supplier, that can mean charging VAT when you should not. If you are the customer, it can mean failing to account for VAT in box 1.

Another mistake is putting the purchase value in box 6. Box 6 is for sales, not purchases. If you are the customer, the net value of the reverse charge purchase normally belongs in box 7.

You should also check your accounting software. Some systems, including QuickBooks, have specific reverse charge VAT codes. If the wrong VAT code is used, the return boxes may be populated incorrectly. A certified QuickBooks accountant can help you set this up properly so you are not manually adjusting every return.

The cash accounting scheme is another area to watch. Reverse charge transactions are not dealt with under the cash accounting scheme in the normal way, even if your business uses cash accounting for other supplies.

Why accurate records matter

Reverse charge VAT is not just about one invoice. It affects your bookkeeping, VAT return, cash flow and HMRC records.

You should keep:

• Copies of all reverse charge invoices issued and received.
• Evidence of your customer’s VAT and CIS status where relevant.
• Any written end user or intermediary supplier notifications.
• Clear VAT codes in your accounting software.
• Notes explaining any corrections or adjustments.

This matters whether you are a limited company, partnership or self-employed contractor. If you are self-employed and working in construction, good sole trader accounting support can help you keep VAT, CIS and tax records in order throughout the year.

Should you get help with reverse charge VAT?

Reverse charge VAT is easy to misunderstand because the VAT is not paid in the normal way. The transaction may have no net VAT cost, but it still needs to be shown correctly on your return.

You may need help if:

• You work with subcontractors.
• You issue both normal VAT and reverse charge invoices.
• Your software is not posting figures to the right VAT boxes.
• You are unsure whether a customer is an end user.
• You have already submitted a VAT return and think it may be wrong.

Good VAT returns services can help you review the figures before filing, correct errors where needed, and make sure your systems are set up properly for future returns.

If you want more confidence with VAT compliance, VAT accountants can guide you through the rules in plain English and help you avoid unnecessary HMRC issues.

FAQs

What is reverse charge VAT in construction?

Reverse charge VAT means the supplier does not charge VAT on certain construction services. Instead, the customer accounts for the VAT on their own VAT return. It usually applies to VAT-registered construction businesses working under CIS where the supply is standard-rated or reduced-rated.

Who pays VAT under the domestic reverse charge?

The customer accounts for the VAT on their VAT return. In many cases, they record the VAT as both output tax and input tax, so the figures cancel out if they can reclaim VAT in full. The supplier does not collect VAT from the customer for that reverse charge supply.

How do you show reverse charge VAT on a VAT return?

If you are the supplier, you do not put output VAT in box 1, but you include the net sale in box 6. If you are the customer, you include the VAT in box 1, reclaim it in box 4 if allowed, and include the net purchase in box 7.

Does reverse charge VAT apply to materials?

If materials are supplied as part of a qualifying construction service, the reverse charge can apply to the full supply. If materials are sold on their own, the treatment may be different, so you should check the nature of the order and whether it falls within CIS.

What is an end user for reverse charge VAT?

An end user is usually a VAT and CIS-registered customer that receives construction services but does not make an onward supply of those services. If they give written confirmation that they are an end user, normal VAT rules can apply instead of the reverse charge.
