Construction VAT reverse charge: does it apply?

This checks the UK domestic reverse charge for building and construction services, not the reverse charge for overseas services. Answer seven questions for a cautious result, and if it likely applies, see the VAT the customer accounts for. Nothing you enter is stored or sent anywhere.

Checked against HMRC

Reverse charge checker and calculator

1. Is the supplier registered for VAT in the UK?

The supplier is the business doing the work and issuing the invoice.

2. Is the customer registered for VAT in the UK?

The customer is the business receiving the work and paying the invoice.

3. Is payment for the supply reported within the Construction Industry Scheme (CIS)?
4. What is the VAT treatment of the construction supply?

This is the VAT rate that would apply to the supply without the reverse charge. The checker takes your answer as given.

5. Is the supplier an employment business supplying staff or workers?
6. Has the customer told the supplier in writing that they are an end user or an intermediary supplier?

Written notification can be by post, by email or in the contract. Without it, the end-user and intermediary-supplier exclusions are not being used.

7. Could any of these apply: a mixed supply of goods and services, linked labour and materials contracts on the same site, or any other unclear classification of the supply?

This checker deliberately does not decide HMRC's two separate 5% concessions. Those are explained below the checker and are different from the 5% reduced VAT rate in question 4. If in doubt, choose Not sure.

Optional. Only used if the result is that the reverse charge likely applies.

When the construction reverse charge applies

HMRC's guidance for suppliers and customers sets out the same conditions. The reverse charge applies from 1 March 2021 to certain building and construction services when all of these are true:

  1. The supplier is registered for VAT in the UK, and the customer is registered for VAT in the UK.
  2. Payment for the supply is reported within the Construction Industry Scheme (CIS).
  3. The supply is standard or reduced rated. Wholly zero-rated construction work is outside the reverse charge.
  4. The supplier is not an employment business supplying staff or workers, or both.
  5. The customer has not told the supplier or building contractor in writing that they are an end user or an intermediary supplier.

Where it applies, the customer accounts for the VAT on their own VAT Return instead of the supplier charging it. HMRC advises suppliers to ask the customer whether they are registered for VAT and for CIS. Not all construction work is reverse charged, and a failed condition does not by itself tell you what VAT treatment does apply.

What goes on the VAT Return

Where the reverse charge applies, VAT Notice 700/12 tells suppliers to fill in box 6 and customers to fill in boxes 1, 4 and 7.

CustomerBox 1Output VAT: the reverse-charge VAT the customer accounts for.
CustomerBox 4Input VAT: the same VAT, reclaimable subject to the customer's normal VAT recovery rules.
CustomerBox 7Purchase value.

What the invoice needs to say

HMRC requires the invoice to include the reference “reverse charge” and make clear that the customer must account for the VAT. The amount of VAT due under the reverse charge should be clearly stated on the invoice, but not included in the amount shown as total VAT charged.

HMRC does not prescribe one form of words. Its guidance gives examples such as “reverse charge: VAT Act 1994 Section 55A applies”, “reverse charge: S55A VATA 94 applies” and “reverse charge: Customer to pay the VAT to HMRC”. Treat these as examples, not the only acceptable wording, and check the current guidance in section 06 before relying on them.

Edge cases this checker deliberately does not decide

The checker returns an edge-case result, with no VAT figure, whenever an answer is Not sure or one of these is flagged. A confident answer here would be a guess.

Minor reverse-charge element: 5% concession

HMRC allows an optional concession where a single supply contains only a minor reverse-charge element worth 5% or less of the whole supply. Supplier and customer must agree from the start of the contract, using the overall contract values rather than testing invoice by invoice. This is not the 5% reduced VAT rate.

Predominant end user with a small re-supply: separate 5% rule

HMRC has a different 5% rule for a VAT-registered customer that is predominantly an end user but re-supplies less than 5% by value. The customer may still choose to issue an end-user declaration. This is separate from the minor-element concession above, and this checker does not decide eligibility for either one.

Mixed goods and services, and supply-and-fix

HMRC says that where goods are supplied with construction services, this is a single supply for VAT purposes. Whether a particular job is one supply or several is a classification question the checker does not answer.

Linked labour and materials contracts

Separate labour and materials contracts for the same site can be treated as one VAT supply where they are linked. The checker cannot tell from a handful of answers whether contracts are linked.

Predominantly zero-rated supplies

The minor-element 5% concession does not apply where there is a single supply and the predominant element is zero-rated. If a job mixes zero-rated and other work, get the treatment confirmed rather than relying on a simple yes or no.

Employment businesses

Supplies of staff or workers by an employment business are excluded even where they are reported within CIS. Deciding whether a business is acting as an employment business for a given supply is beyond this tool.

End users and intermediary suppliers

These exclusions depend on the customer notifying the supplier in writing. The checker only asks whether that written notification exists. It does not decide whether a customer qualifies as an end user or intermediary supplier.

Zero-rating and unclear classification

Whether work qualifies for zero-rating (for example on a new dwelling) or the reduced rate has its own conditions. The checker takes your stated rate as given and treats Not sure as an unresolved question.

VAT Cash Accounting Scheme

Transactions that are subject to the domestic reverse charge are excluded from the VAT Cash Accounting Scheme and must be accounted for under the reverse-charge rules. A business can still use cash accounting for other qualifying supplies and purchases.
