Reverse charge VAT

What reverse charge VAT is, when the UK construction reverse charge and cross-border B2B services rules apply in 2026, and how to record the entries.

Definition

Reverse charge VAT is a VAT accounting mechanism that shifts the obligation to account for VAT from the supplier to the customer. The supplier issues an invoice with no VAT charged. The customer self-accounts for both the output VAT (as if it had sold the supply) and the input VAT (as if it had bought the supply), so the net VAT effect on its return is zero. The mechanism is used to combat fraud and to simplify cross-border B2B services.

What reverse charge VAT means in practice

For a UK bookkeeper, the reverse charge is most often seen in two contexts: cross-border B2B services and UK construction industry payments. Each follows the same mechanic but applies in different circumstances and uses different VAT-return entries.

The cross-border B2B services rule applies to services bought from overseas suppliers under the general place-of-supply rule. A UK consultancy buying CRM software from a US supplier records the bill at the net amount, posts the offsetting output and input VAT entries, and shows the supply in boxes 1, 4, 6, and 7 of the VAT return. The net VAT effect is zero (output and input cancel) but the disclosure on the return is what HMRC uses to track these cross-border flows.

The construction industry rule applies to most construction services between VAT-registered businesses since 1 March 2021. A sub-contractor sends an invoice to the main contractor with no VAT charged and a “reverse charge applies” annotation. The main contractor self-accounts for the VAT, which removes the missing-trader fraud opportunity that previously plagued the sector.

A practical example: a UK construction sub-contractor invoices a main contractor 50,000 for plastering. Under reverse charge, the invoice carries no VAT and includes the wording “Reverse charge: customer to pay the VAT to HMRC”. The main contractor posts the 50,000 cost, then a manual journal of 10,000 output VAT (debit input VAT, credit output VAT). Net VAT effect on the return: zero. The 50,000 net appears in box 6 (the supplier’s reverse-charge total) of the customer’s VAT return; the 10,000 output VAT in box 1, the 10,000 input VAT in box 4.

How reverse charge VAT works by country

United Kingdom

Two main applications. Cross-border B2B services: under the general place-of-supply rule, services are deemed supplied where the customer belongs, so the customer self-accounts for the VAT. Construction industry: since 1 March 2021, construction services between VAT-registered businesses use reverse charge under the CIS reverse-charge rules. The supplier’s invoice must clearly state that the reverse charge applies and that the customer is responsible for accounting for the VAT.

The construction rule is narrower than the cross-border rule. It excludes: zero-rated supplies, supplies to end users (defined in HMRC guidance), and supplies where the customer is not VAT-registered. The end-user rule is the most common source of misclassification: a main contractor who acquires materials for a project they will sell on as a finished property is an end user for some supplies and not for others.

Australia

Australia does not have a general reverse-charge mechanism for indirect tax. GST place-of-supply rules generally place B2B supplies at the supplier’s location. Specific narrow reverse-charge rules apply for some imported services to non-registered customers, but the general business-to-business pattern uses supplier-side GST.

New Zealand

New Zealand has a narrow reverse-charge rule for imported services where the customer is GST-registered and the supply is for a non-taxable purpose. The default for B2B supplies is supplier-side GST under the GST Act 1985.

Canada

Canada has self-assessment requirements for imported services and intangible personal property used in Canada that approximate a reverse charge. The customer self-assesses GST/HST and remits it on the next return. The rule mainly affects digital services and IP licences from non-resident suppliers.

Singapore

Singapore introduced a reverse-charge regime for imported services on 1 January 2020. GST-registered businesses receiving imported services for non-taxable purposes must self-account for GST under reverse charge. The rule was expanded on 1 January 2023 to cover B2C imported low-value goods (the Overseas Vendor Registration regime).

Reverse charge VAT modifies the standard VAT flow:

  • VAT is the UK indirect tax this mechanism operates within.
  • Input VAT is one half of the offsetting reverse-charge entry.
  • Output VAT is the other half.
  • A tax invoice must include the reverse-charge wording when the mechanism applies.
  • MTD record-keeping rules cover reverse-charge entries the same as other VAT transactions.
  • CIS is the wider UK Construction Industry Scheme that includes the construction reverse charge.

Questions, answered

Common questions

Why does the UK use reverse charge for construction?

To combat 'missing trader' VAT fraud. Before the reverse charge, sub-contractors would charge VAT to main contractors but disappear without remitting it to HMRC. Under reverse charge the main contractor accounts for the VAT itself, so the fraud opportunity is removed. The 1 March 2021 introduction targeted construction specifically because it was the highest-fraud sector.

How do I record a reverse-charge transaction in Xero?

Xero has a dedicated 'Reverse Charge Expenses' tax rate for UK construction reverse charge. The bill is posted with the net amount, no input VAT is recorded on the bill itself, and the system creates the offsetting output and input VAT entries automatically so the net VAT effect is zero. The VAT return shows the supplies in box 6 (sales) and box 7 (purchases) but with zero VAT in boxes 1 and 4.

Does reverse charge affect my cash position?

Yes, it improves it for the customer. Without reverse charge, the customer pays VAT to the supplier and then reclaims it on the next VAT return, which creates a short-term cash outflow. Under reverse charge, no VAT moves between the parties at all. The supplier loses the short-term cash benefit; the customer keeps it.
