At a glance
The Construction Industry VAT Domestic Reverse Charge (DRC) measure applies to supplies of construction work from 1 March 2021. The measure had been due to commence in October 2019, but was Delayed twice due to Brexit and the Coronavirus.
- Under the CIS DRC, the customer accounts for the supplier's output VAT.
- This measure only applies to construction supplies made by a business to another business.
Apply the reverse charge when all the following are met:
- There is a supply for VAT of construction services and materials.
- The supply is made at the standard or reduced rate of VAT.
- The supply is made between a UK VAT registered supplier and UK VAT registered customer.
- Both supplier and customer are registered for the CIS.
- The customer intends to make an ongoing supply of construction services to another party.
- The supplier and customer are not connected.
- The supplier is not an employment business.
- The customer is not an 'end-user'.
The CIS reverse charge does not apply to any of the following supplies:
- Supplies of VAT exempt building and construction services.
- Supplies that are not covered by the CIS, unless linked to such a supply.
- Supplies of staff or workers.
- Supplies of materials only.
The CIS reverse charge does not apply to taxable supplies made to the following customers:
- A non-VAT registered customer.
- 'End-users' i.e. a VAT registered customer who is not intending to make further ongoing supplies of construction.
- 'Intermediary suppliers'.
The aim of the measure is to reduce VAT fraud in the construction sector.
It will have required a significant change of approach in many CIS businesses:
- Staff need to be trained to identify relevant CIS contracts and end-users.
- Accounting and bookkeeping systems need to be modified to cope with the new invoicing and reporting obligations.
- The use of the VAT Flat rate scheme and Cash accounting may not be possible.
- Cash flow will be affected and those at the start of the supply chain may become VAT repayment claimants: they need to consider whether to file monthly returns.
- It may require a business that is the recipient of the supply to VAT register.
Example: How the CIS reverse charge works
John the Roofer (who is VAT registered) supplies the materials and roofs a new office building for Mr Contractor (who is also VAT registered) and in turn, supplies its construction services to Ms Developer (also VAT registered). Ms Developer finds and develops land and will, in this case, bring the build to completion and supply a finished commercial building to Enduser, its client.
- John the Roofer would under the old VAT system, invoice Mr Contractor £120,000, comprising of his £100,000 bill for materials, labour and works, plus £20,000 in VAT (at 20%).
From March 2021, under the new CIS reverse charge mechanism, he invoices £100,000. His invoice states that 'the CIS reverse charge applies' (see invoicing requirements in subscriber guide: CIS: Construction Industry reverse charge) and that the applicable rate of VAT is 20%.
- Mr Contractor pays John the net £100,000 fee. It then accounts for output and input VAT of £20,000 on the supply on its own VAT return.
- John does not account for output VAT in his accounting system as he has invoiced only his fee of £100,000.
- As a consequence of the reverse charge procedure, John charges and receives £20,000 less than under the old system (where he would charge £100,000 + VAT). He does not have to account to HMRC for any output tax on the transaction.
- When he is paid by Mr Contractor he includes the value of the sale in box 6 of his VAT return. He does not add VAT to box 1 as he receives no output VAT.
- The change may well impact John’s cash flow, as under the old rules, if Mr Contractor was a prompt payer he could hope that he could use the £20,000 in VAT to purchase his materials. He could then purchase his materials and offset the input tax paid against his output liability.
- Mr Contractor has a cash flow advantage, he does not have to pay John £20,000 and then at the end of its VAT quarter it cannot reclaim £20,000 as it is accounting for the reverse charge and the output VAT offsets the input VAT.
- As Mr Contractor is supplying CIS services it must also consider the reverse charge. Will its client (Ms Developer) be involved in the onward supply of CIS services? In this case, this may be difficult to determine as apparently Ms Developer is selling a finished building to Enduser as an investor and the reverse charge does not apply. It is Ms Developer's responsibility to notify down the supply chain.

Certain services can become included
- If there is a reverse charge element in a supply, then the whole supply will be subject to the domestic reverse charge.
- If there has already been a reverse charge service between two parties on a construction site, and if both parties agree, any subsequent construction supplies on that site between the same parties can be treated as reverse charge services.
- If there is doubt whether a type of works falls within the definition of a specified service, as long as the recipient is VAT registered and the payments are subject to CIS, the reverse charge should apply.
- The contractor is asked to consider all construction contracts with a sub-contractor. If they can see that the reverse charge applies to more than 5% of contracts (by volume or value) with that sub-contractor, then the reverse charge may be applied to all of the contracts.
- A joiner constructing a staircase offsite and then installing it onsite is making a reverse charge service, even if the charge for installation is only a minor element of the overall charge.
Treatment of existing contracts at 1 March 2021
The VAT treatment is determined for payments due on any supplies entered into your accounting system before 1 March 2021, but paid on or after 1 March 2021.
|Date entered in customer’s accounting system
|Date payment made
|Before 1 March 2021
|On or before 31 May 2021
|Normal VAT rules
|Before 1 March 2021
|On or after 1 June 2021
|Domestic reverse charge
|On or after 1 March 2021
|On or after 1 March 2021
|Domestic reverse charge
For contracts starting after 1 March 2021, you should decide whether the reverse charge applies from the start of the contract.
- Cash accounting cannot be used for CIS reverse charge.
- Businesses will need to review their schemes.
- If a business is likely to become a VAT repayable business it will be beneficial for it to move to monthly VAT returns.
- Where both the supplier and the recipient are VAT registered or should be VAT registered, the recipient is liable to account for and pay the VAT to HMRC on behalf of the supplier.
- The supplier will not make a VAT payment on those supplies.
When supplying a service subject to the CIS reverse charge, suppliers must show all the information that is normally required on a VAT invoice, except that:
- A note on the invoice must make clear that the CIS reverse charge applies and that the customer is required to account for the VAT.
- No VAT is charged on the invoice.
- It should state how much VAT is due under the reverse charge, or the rate of VAT if the VAT amount cannot be shown, but that VAT should not be included in the amount charged to the customer.
Under VAT Regulation 1995, invoices for services subject to the reverse charge where the customer is liable for the VAT must include the reference ‘reverse charge’. Here are some examples of wording that meets the legal requirement:
- Reverse charge: VAT Act 1994 Section 55A applies.
- Reverse charge: S.55A VATA 94 applies.
- Reverse charge: Customer to pay the VAT to HMRC.
