If you’re in the Construction Industry Scheme (CIS) and VAT registered, HMRC have recently announced a further delay to the implementation of the new VAT reverse charge rules.
The new rules are now planned to be introduced on 1st March 2021 and will change how you account for VAT. The new rules are complex and you may need to change the way you present information on your invoices to your customers and prepare your VAT returns.
What is the VAT reverse charge?
The reverse charge is a way of accounting for VAT where the end-customer accounts for VAT and the supplier of construction services does not. The reverse charge means the customer receiving construction services has to pay the VAT to HMRC instead of the supplier. The end-customer recovers VAT subject to the normal rules set by HMRC.
How are the new rules applied?
When introduced, the new rules apply to standard rate VAT or reduced-rate construction services provided by VAT registered businesses. The reverse charge does not apply to supplies of services which are zero-rated, such as the construction of housing. If you don’t make an onward supply of construction services, you are the end customer and normal VAT rules apply.
If invoices have CIS and non-CIS registered supplies, the reverse charge applies to the whole invoice amount.
A typical situation where the reverse charge applies is where a sub-contractor makes a supply of services to a customer (or contractor) who then makes an onward supply of the same construction services to another customer. A typical supply chain is shown below. All parties in the chain are VAT registered. When the customer confirms they are the end of the supply chain, normal VAT rules apply.

How does this affect me?
That depends on your position in the supply chain highlighted above. You can use the following flowchart to work out if you should apply the reverse charge or whether normal VAT rules apply.

What do I have to do?
If you are a subcontractor
If you’re invoicing a customer (or contractor) in a supply chain, you’ll either have to charge VAT as normal or apply the reverse charge. For the reverse charge, your invoice total will not include VAT.
However, your invoice must include a statement advising your customer (or contractor) that the reverse charge rules apply, stating the amount of output VAT to be applied (20% if it’s the standard rate of VAT). Your customer (or contractor) will need to include that amount on their VAT return. You do not include anything on your VAT return about the reverse charge.
Your customer (or contractor) will need to include that amount on their VAT return. You do not include anything on your VAT return about the reverse charge.
If you are a main contractor
If you are a main contractor receiving a VAT reverse charge invoice from a subcontractor, you should continue to record it as a normal expense invoice and include input VAT on your VAT return.
You’ll also need to account for the reverse charge VAT the subcontractor has notified you about. The overall effect on your VAT liability is neutral as the output VAT is covered by the input VAT
Other matters
It may be possible to be a subcontractor on one project and a main contractor on another, so you need to consider the VAT status of your services for each construction project you work on.
If you’re currently on the Flat Rate VAT Scheme and the majority of your supplies are affected by the VAT reverse charge, you might want to consider changing to the Standard VAT scheme as:
- The Flat Rate Income amount will be reduced, possibly to nil
- You will be losing the opportunity to reclaim input VAT on expenses.
In the lead up to 1st March 2021, we recommend that you speak to an accountant or specialist tax advisor if you believe the new reverse charge VAT rules apply to your business.
