VAT reverse charge for construction

The VAT domestic reverse charge for construction services changes how VAT is accounted for on supplies of certain construction services. Instead of the supplier charging VAT to the customer and paying it to HMRC, the customer accounts for the VAT directly on their own VAT return.

This rule has been in effect since 1 March 2021 and applies to most construction industry transactions between VAT-registered businesses. Getting this wrong can lead to accounting errors, cash flow problems, and potential penalties from HMRC.

Who this guide is for

This guide is relevant if you are:

• A subcontractor providing construction services to other contractors
• A main contractor receiving construction services from subcontractors
• An end user (such as a landlord or retailer) having construction work done
• An accountant or bookkeeper handling VAT for construction businesses

What the reverse charge is

Under normal VAT rules, the supplier charges VAT on their invoice, collects it from the customer, and pays it to HMRC through their VAT return. The customer reclaims the VAT they paid through their own VAT return.

Under the reverse charge, this process changes:

• The supplier does not charge VAT on their invoice
• The supplier invoices only the net amount
• The customer accounts for the VAT themselves on their VAT return
• The customer includes the VAT in both their output tax (Box 1) and input tax (Box 4)

The effect is that the VAT goes directly to HMRC via the customer's return, rather than passing through the supplier first.

When the reverse charge applies

The reverse charge applies when all of the following conditions are met:

1. The supply is of specified construction services (see list below)
2. The supply is standard-rated (20%) or reduced-rated (5%) for VAT - zero-rated supplies are excluded
3. Both the supplier and customer are VAT-registered in the UK
4. The customer is registered for CIS (Construction Industry Scheme) or is required to register
5. The customer is NOT an end user or intermediary supplier
6. The supply is one that is reported within CIS

If any of these conditions is not met, normal VAT rules apply - the supplier charges VAT in the usual way.

Services covered by the reverse charge

The reverse charge applies to services that qualify as construction operations under CIS. These are the same categories covered by CIS, with minor exceptions.

When the reverse charge does NOT apply

The reverse charge does not apply in several important situations. Understanding these exceptions helps you invoice correctly and avoid errors.

Understanding end users

The end user exception is crucial. An end user is a business that:

• Receives construction services but
• Does NOT make onward supplies of those same services to another party

Examples of end users:

• A retailer having a shop fitted out - the construction services stop with them
• A manufacturer having a factory extended - they make products, not construction services
• A landlord having repairs done to a rental property - they supply property, not construction
• A developer who sells completed buildings but does NOT sell the construction services themselves

Examples of businesses that are NOT end users:

• A main contractor receiving services from subcontractors - they make onward supplies of construction to their client
• A labour-only subcontractor who subcontracts part of their work - they make onward supplies

Key test: If you receive construction services and then include those services (directly or as part of a larger project) in what you supply to your customer, you are NOT an end user.

Getting written confirmation from end users

If your customer claims to be an end user, you need written confirmation from them. Without this, you must apply the reverse charge.

Practical tips for end user confirmation

• Get it in writing before starting work - include end user status in your contract or get a separate signed statement
• Keep copies - retain the confirmation with your VAT records for 6 years
• Challenge obvious errors - if a main contractor claims end user status, query it. You cannot rely on confirmation that is obviously incorrect
• Review ongoing relationships - if a customer's circumstances change, they may no longer be an end user

Invoice requirements under the reverse charge

When the reverse charge applies, your invoice must be different from a normal VAT invoice. Getting this right is essential for both your records and your customer's VAT return.

Key invoicing rules

• Do NOT show a VAT amount - show only the net value
• Do show the VAT rate that would have applied (20% or 5%)
• Include the reverse charge annotation - something like: "Reverse charge: Customer to account to HMRC for the reverse charge output tax on the VAT exclusive price of items marked 'reverse charge'"
• Include customer's VAT number - essential for their records
• Keep normal invoice requirements - all other standard invoice requirements still apply

Example invoice layout

For construction services worth 10,000:

• Net amount: 10,000
• VAT rate: 20%
• VAT amount: 0.00 (Reverse charge applies)
• Total payable: 10,000
• Note: "Reverse charge: Customer to account to HMRC for the reverse charge output tax"

Accounting treatment

Both the supplier and customer must handle VAT differently under the reverse charge. Understanding this helps you complete your VAT return correctly.

Cash flow impact

The reverse charge significantly affects cash flow for construction subcontractors. This is one of the most important practical consequences of the rules.

Practical steps to manage cash flow

• Consider monthly VAT returns: If you regularly reclaim more input VAT than you charge in output VAT, switch to monthly returns to get refunds faster
• Review pricing: Your tender prices should reflect that you no longer hold VAT between receiving payment and paying HMRC
• Adjust budgets: Remove the temporary VAT cash benefit from your working capital calculations
• Talk to your bank: If cash flow is tight, explain the regulatory change - they may offer additional facilities

Mixed supplies and sub-contracts

Construction projects often involve mixed supplies - some services subject to the reverse charge and others not. Understanding how to handle these is essential.

Materials supplied with labour

When you supply materials together with construction labour:

• If the main purpose is construction services (labour is the substance), the whole supply is subject to the reverse charge
• If you are making a separate supply of materials and a separate supply of labour, apply the reverse charge only to the labour element

In practice, most construction contracts where materials are installed as part of a building project are treated as a single supply of construction services.

The 5% disregard

Where the reverse charge element of a supply is 5% or less of the value of the whole supply, you and your customer may disregard it and apply normal VAT rules to the whole supply.

Multiple VAT rates

Some construction services are reduced-rated (5%) rather than standard-rated (20%). The reverse charge applies to both rates. Your invoice should clearly show which rate applies to which services.

Zero-rated new builds

Construction of new residential dwellings is often zero-rated. The reverse charge does NOT apply to zero-rated supplies - the supplier invoices at zero VAT in the normal way.

Common mistakes to avoid

• Charging VAT when reverse charge applies: If you charge VAT when you should not have, your customer may refuse to pay the VAT element. You remain liable to account for it to HMRC
• Not charging VAT to end users: If you fail to charge VAT to genuine end users, you are still liable to account for the VAT
• Accepting end user claims without written confirmation: HMRC expects you to obtain and retain written confirmation. Verbal claims are not sufficient
• Using incorrect invoice wording: The reverse charge annotation must be clear and unambiguous
• Confusing CIS with VAT: CIS deductions are separate from VAT. The reverse charge affects VAT treatment; CIS deductions continue to operate normally
• Forgetting about partially exempt customers: If your customer cannot recover all their input VAT, the reverse charge creates a real cost for them as Box 4 will be lower than Box 1

Relationship with CIS

The VAT reverse charge and the Construction Industry Scheme (CIS) are connected but separate:

• CIS requires contractors to make deductions from subcontractor payments and report these to HMRC
• VAT reverse charge changes who accounts for VAT to HMRC
• The reverse charge applies to supplies that are reportable within CIS
• If you are CIS-registered as a contractor, you are likely within scope of the reverse charge when receiving construction services

The CIS deduction (if applicable) is calculated on the net payment - the VAT-exclusive amount. The reverse charge does not change how CIS deductions work.
