What the domestic reverse charge is and why it exists
The VAT domestic reverse charge (DRC) for construction services came into force on 1 March 2021 and has not been altered by Finance Act 2026. It is an anti-fraud measure, designed to close a specific missing-trader VAT fraud that had taken hold in the construction sector. Under the fraud, a sub-tier supplier would charge VAT, collect it from the customer, and then disappear without paying it to HMRC. The DRC removes the opportunity by moving the obligation to account for VAT from the supplier to the customer.
The practical effect is this: instead of a subcontractor charging 20% VAT on their invoice and remitting it to HMRC through their own VAT return, the customer (the main contractor or upper-tier subcontractor) accounts for the VAT in their own return. The subcontractor invoices for the net amount only. No VAT changes hands between the two parties. The customer declares the VAT as both output and input tax on the same return, and the net cash effect on a fully-recovering business is nil. The subcontractor, however, no longer collects VAT at all, which has real cash-flow consequences that are covered below.
The DRC applies on top of, and separately from, the Construction Industry Scheme. The two regimes interact but are not the same thing. CIS governs deductions from labour payments as an advance against income tax and National Insurance. The DRC governs who accounts for VAT. A single invoice can attract both CIS deductions and the VAT reverse charge at the same time, and the calculations run independently.
The five conditions: all must be met
The DRC is not a blanket rule covering all construction work. It applies only when all five of the following conditions are satisfied. If any one of them is not met, normal VAT rules apply and the supplier charges VAT in the usual way.
| Condition | What it means in practice |
|---|---|
| 1. Specified CIS service | The supply must be a construction service caught by CIS: building, alteration, repair, extension, demolition, installation of heating/plumbing/electrical/ventilation systems, internal cleaning of structures during construction, painting and decorating, and most civil engineering works. Design, surveying, scaffolding (in certain limited circumstances) and manufacturing of components off-site are excluded from CIS and therefore from the DRC. |
| 2. Both parties VAT-registered | The supplier and the customer must each be registered for VAT. If either party is below the VAT registration threshold or is not registered, normal VAT rules apply to the supply. |
| 3. Both parties CIS-registered | The supplier and the customer must both be registered under the Construction Industry Scheme. A customer who is not CIS-registered is outside the DRC, even if they are VAT-registered. This is the condition that most often catches out customers who are VAT-registered but have not registered for CIS because they mistakenly believed CIS did not apply to them (for example, a property developer who engages contractors but has not registered as a deemed contractor). |
| 4. Customer is not the end user | The customer must be making an onward supply of the construction services, not consuming them themselves. If the customer is the end user (property owner, tenant fitting out their own space, developer building for their own portfolio), normal VAT applies. See the full end-user section below. |
| 5. Standard-rated or reduced-rated supply | The supply must be standard-rated (20%) or reduced-rated (5%). Zero-rated supplies, most importantly new-build residential construction, are outside the DRC. A subcontractor working on qualifying new-build residential work charges VAT at 0% in the normal way. |
Each condition is independent. Miss any one of them and the DRC does not apply. Suppliers should keep a record confirming each condition is satisfied at the time of invoice, particularly conditions 3 and 4, which are most likely to change over the life of a relationship.
Worked example A: what a reverse-charge invoice looks like
Below is a side-by-side comparison showing how the same job is invoiced under normal VAT rules versus under the DRC. The scenario: a bricklaying subcontractor (registered for VAT and CIS) invoices a main contractor (also registered for VAT and CIS) for £4,000 of labour and £1,000 of materials on a refurbishment of a commercial office. All five DRC conditions are met.
| Normal VAT (end user or either party not CIS-registered) | Domestic Reverse Charge (all 5 conditions met) | |
|---|---|---|
| Labour | £4,000.00 | £4,000.00 |
| Materials | £1,000.00 | £1,000.00 |
| Net total | £5,000.00 | £5,000.00 |
| VAT at 20% | £1,000.00 | £0.00 |
| Invoice total | £6,000.00 | £5,000.00 |
| VAT note on invoice | (none needed) | "Reverse charge: customer to account for VAT to HMRC at 20% on the VAT-exclusive price shown (£5,000). VAT amount: £1,000." |
| Who pays VAT to HMRC | Subcontractor (via their own return) | Main contractor (via their own return) |
Key points on the reverse-charge invoice:
- The subcontractor invoices for £5,000 only. There is no VAT line charged to the customer.
- The invoice must state the VAT rate that would have applied (20% here) and the VAT amount (£1,000), so that the customer knows exactly what to declare.
- The invoice must carry the reverse-charge legend. HMRC's standard wording is: "Reverse charge: customer to account for VAT to HMRC at the applicable rate on the VAT-exclusive price shown."
- The subcontractor records £5,000 net in box 6 (value of sales) of their VAT return. They do NOT include the £1,000 as output tax in box 1.
- The main contractor records £1,000 as output tax in box 1 and (assuming full recovery) the same £1,000 as input tax in box 4. The net VAT effect on the main contractor's return is zero.
Now add CIS into the same example. The main contractor is the contractor under CIS and the bricklayer is a registered subcontractor (20% rate, not GPS). CIS applies to the labour element only, which is £4,000. The deduction is 20% of £4,000, which is £800. The main contractor pays the subcontractor £5,000 (the reverse-charge invoice total) minus £800 CIS deduction, giving a net payment of £4,200. The CIS deduction statement to HMRC covers £800 on £4,000 labour. The materials portion of £1,000 is not subject to CIS deduction.
The end-user exception: the most widely misunderstood part
The single condition that generates most practical confusion is condition 4: the customer must not be the end user. Many contractors assume that because they are the "contractor" in CIS terms, the DRC automatically applies to supplies made to them. It does not. What matters is whether the customer will consume the building work themselves or pass it on.
Under HMRC's rules, the following are end users:
- A property owner commissioning work on their own building (whether they live there, let it, or use it for their own business).
- A tenant fitting out or refurbishing their own leasehold premises.
- A property developer constructing or refurbishing buildings that they intend to hold in their portfolio, let to tenants, or sell as finished units. The developer is receiving the construction services for their own benefit, not buying construction from subcontractors to sell on as construction services.
- A company building a new factory or office for its own use.
In every case above, the customer consumes the building work. The subcontractor should charge VAT in the normal way. The reverse charge does not apply.
Worked example B: developer building for own use
This is the scenario that catches out subcontractors most often. A regional housebuilder (VAT-registered, CIS-registered as a deemed contractor because they spend over £3 million a year on construction work) engages a plastering subcontractor to plaster 40 new flats in a development. The developer will sell the completed flats to individual buyers.
Question: does the DRC apply to the plastering subcontractor's invoices to the developer?
Answer: No. The developer is the end user. Although the developer is CIS-registered and VAT-registered, they are not making an onward supply of plastering services. They are incorporating the plastering work into finished flats that they will sell. The construction services end with the developer. The plastering subcontractor must charge VAT at the standard rate (20%) in the normal way on their invoices to the developer.
An additional point for new-build residential: the developer's onward sale of the new flats to buyers is zero-rated for VAT, and the developer can recover the input VAT they paid to the plasterer. But that is a separate VAT recovery question for the developer, not a reason to omit VAT from the plastering invoices in the first place.
Compare this with a different scenario: the same plastering subcontractor is engaged by a main contractor who has taken on the plastering package from the developer and is supplying plastering services onward to the developer as construction services. Here the main contractor is NOT the end user; they are selling construction services to the developer. All five DRC conditions can be met, and the DRC would apply between the subcontractor and the main contractor (but not, again, between the main contractor and the developer, because the developer is the end user).
The practical rule: trace the chain and ask at each level whether the customer is receiving construction services as a service they are buying in (end user) or as something they are going to sell on. The end-user status attaches to the party that will consume the completed work, regardless of how large they are or whether they happen to be registered under CIS in their capacity as a deemed contractor.
Intermediary suppliers
There is a related category worth noting. An intermediary supplier is a business connected to the end user (for example, a subsidiary or group company) that contracts for the construction work and passes it on to the end user. Intermediary suppliers can notify their supplier that they should be treated in the same way as an end user, in which case the DRC does not apply between them. HMRC requires this notification to be in writing. If the subcontractor receives a written intermediary supplier notice, keep it on file and charge VAT normally.
The 5% de minimis rule
If the reverse charge would apply to 5% or less of the total value of an invoice, normal VAT rules apply to the entire invoice. The DRC is ignored for the whole amount.
Example: a specialist contractor invoices a main contractor for the supply and installation of bespoke kitchen units. The total invoice is £20,000. Of that, £18,500 relates to the supply of manufactured units (excluded from CIS, outside the DRC) and £1,000 relates to installation labour and £500 to associated materials (CIS services, potentially within the DRC). The CIS element is £1,500, which is 7.5% of £20,000. Since 7.5% is above 5%, the de minimis does not apply and the DRC applies to the CIS portion. The supplier would need to split the invoice or find a workable presentation to reflect the two different VAT treatments.
Change the figures so the installation element is only £900 (4.5% of £20,000). Now the de minimis applies. The supplier charges VAT normally on the whole invoice. No splitting is required.
The 5% test uses the value of the supply that would attract the DRC as the numerator, over the total invoice value as the denominator. Where invoices routinely mix CIS and non-CIS elements, knowing this threshold avoids unnecessary complexity.
Zero-rated new-build: outside the DRC entirely
New-build residential construction (and certain conversions and renovations qualifying for the zero rate under VATA 1994 Schedule 8) is zero-rated, not standard-rated. Condition 5 of the DRC test requires the supply to be standard-rated or reduced-rated. Zero-rated work therefore falls entirely outside the DRC, regardless of whether the other four conditions are met.
A subcontractor on a zero-rated new-build site invoices at 0% VAT in the normal way. There is no reverse-charge obligation on either party. The zero-rate is a fundamental VAT exemption from the construction chain, not a variant of the reverse charge.
Note that partial new-build sites can be complex. A development that includes qualifying new-build residential units and non-qualifying commercial or mixed-use elements may have different VAT treatments for different parts of the work. Where there is genuine mixed-use complexity, specialist VAT advice is the right approach rather than a blanket assumption about the whole site.
Cash-flow impact for subcontractors
The DRC has a material cash-flow effect on subcontractors that is often underestimated when a business first encounters it.
Under normal VAT rules, a subcontractor collects 20% output VAT from their customers on each invoice. If they invoice £10,000 a month net, they collect £2,000 in VAT, and they hold that money until their quarterly VAT return is due (then pay net of any input VAT they have themselves incurred). The VAT float, roughly three months of output VAT, can be a meaningful source of working capital, particularly for a business in growth.
Under the DRC, the subcontractor no longer collects any VAT. They invoice at net only. The VAT float disappears. At the same time, the subcontractor continues to pay input VAT on materials, tools, vehicles and other business expenses. With output VAT reduced to zero (or close to it on a predominantly-DRC book of work), the subcontractor is very likely in a net VAT repayment position each period. On a quarterly VAT return that means reclaiming from HMRC once every three months, with repayment taking up to a further 30 days in practice.
The practical response is to switch to monthly VAT returns. Monthly returns allow the subcontractor to reclaim input VAT every month rather than every quarter. For a subcontractor spending £2,000 a month on materials (including 20% VAT), switching from quarterly to monthly returns accelerates £400 of VAT recovery per month. Over a year, that can represent a significant improvement in available cash.
Switching to monthly returns is a simple application to HMRC online. There is no requirement to demonstrate a reason and no financial cost. Most subcontractors for whom the DRC applies to the majority of their work should be on monthly returns. If you are currently on quarterly returns and a significant portion of your construction income is subject to the DRC, speak to your accountant about making the switch. The Trade Tax Specialists services page covers how we help subcontractors with VAT compliance alongside CIS.
How the DRC and CIS interact on the same payment
It is common for the same payment to attract both the VAT reverse charge and a CIS deduction. The two calculations run independently, but understanding the order avoids errors.
CIS deductions apply to the labour element of the net (ex-VAT) payment. Under the DRC, no VAT is charged by the subcontractor, so the net payment is also the gross payment from the contractor's perspective. The CIS deduction is then applied to the labour portion of that net figure. Materials are excluded from the CIS deduction base, as with all CIS payments. For more detail on how CIS deductions work, including the labour-only rule, see our guide to CIS deduction rates.
Example: a groundworker (registered CIS subcontractor, 20% CIS rate) invoices a main contractor under the DRC for £6,000 net (£4,500 labour, £1,500 materials). The main contractor accounts for VAT of £1,200 (20% of £6,000) in their own VAT return, with no cash movement between the parties on account of VAT. The CIS deduction is 20% of £4,500 (labour only), which is £900. The main contractor pays the groundworker £6,000 minus £900 CIS, netting to £5,100.
| Component | Amount | Note |
|---|---|---|
| Labour (net) | £4,500 | Subject to CIS deduction |
| Materials (net) | £1,500 | Excluded from CIS deduction base |
| Invoice total (net) | £6,000 | No VAT charged (DRC applies) |
| VAT (accounted for by contractor) | £1,200 | Contractor declares in their own return |
| CIS deduction (20% of £4,500 labour) | £900 | Deducted from payment by contractor |
| Net payment to groundworker | £5,100 | £6,000 minus £900 CIS deduction |
Practical checklist before raising a reverse-charge invoice
Before treating an invoice as subject to the DRC, confirm each of the following:
- The work is a specified CIS service (not design, surveying, or manufactured components only).
- You (the supplier) are VAT-registered.
- Your customer is VAT-registered (request their VAT number if you do not have it and record it).
- Your customer is CIS-registered (confirm their status via the HMRC CIS verification service, which also serves the subcontractor verification duty under CIS).
- Your customer is not an end user or intermediary supplier. If there is any doubt, obtain a written statement from the customer confirming they are not the end user and that they will account for VAT under the reverse charge.
- The supply is standard-rated or reduced-rated, not zero-rated.
- The CIS element of the invoice exceeds 5% of the total invoice value (if the invoice mixes CIS and non-CIS supplies).
Keep written evidence of conditions 3, 4 and 5 for each customer relationship. HMRC can ask suppliers to demonstrate why the DRC was applied, and a file note or customer declaration is far more defensible than a verbal understanding.
Getting the DRC right as a CIS subcontractor
For most CIS subcontractors, the domestic reverse charge is one of several compliance obligations running in parallel: CIS deductions, Self Assessment or corporation tax, MTD for Income Tax (for those above the £50,000 gross income threshold from April 2026), and now the DRC. Each has its own rules and deadlines, and errors in one can create knock-on problems in another.
The most common DRC errors in practice are: charging VAT when the DRC should apply (which creates a VAT debt for the supplier and a recovery headache for the customer), failing to charge VAT when the customer is an end user (which is equally wrong in the other direction), and staying on quarterly VAT returns when a predominantly-DRC workbook makes monthly returns materially better for cash flow.
If you also need to split an invoice between labour and materials for CIS purposes, our CIS invoice splitter shows how the deduction is calculated on the labour element alone.
If you are a subcontractor trying to get the right VAT treatment across a mixed book of work, or a main contractor uncertain whether a particular customer is an end user, the Trade Tax Specialists accounting services for construction businesses cover VAT compliance, CIS compliance and tax planning as an integrated service.
