In this blog, we go through what happens regarding the domestic reverse charge for supplies of building and construction services from the 1st of March 2021.

So, to start with, below is the flow chart which explains whether the Domestic VAT reverse charge must be used for your business. You need to sequentially assess the scenario and check whether the reverse charge VAT will be applicable for you.

Question 1: Does the supply fall within scope of CIS?

To decide whether the supply to CIS-registered customers falls within the purview of CIS, important considerations must be made.

Generally, the following services provided to CIS-registered customers are applicable for the reverse charge of VAT:
– Construction, altering, repairing, or demolishing of building.
– Internal cleaning 0f building if it’s part of construction, alteration of repair work.
– Installing heating lighting drainage or similar system.
– Internal external painting or decorating of building.
– Construction, altering, repairing or demolishing any work foaming part of land – like walls, roadwork, or powerlines.
– Preparation or completion work of other specified services – Site clearance, excavation, landscaping etc.

Other CIS ‘Specified Services’ can be found on Construction Industry Scheme: a guide for contractors and subcontractors (CIS 340) – GOV.UK (

Question 2: Is the supply chargeable at standard rate or zero rate?
If VAT is chargeable at standard rate or reduced rate, then move on to check your applicability for the next question.
Question 3: Is your customer VAT-registered?
On VIES ( , the information can be found regarding whether the customer for the sub-contractor (which may be mostly contractor) is VAT registered.
Alternatively, the customer may periodically issue a statement of CIS deductions which carries VAT registration details of customer.

Question 4: Is your customer is registered for CIS?

The web page below can be used to verify whether a customer is registered for CIS services:
Construction Industry Scheme (CIS) online service – GOV.UK (

Question 5: Has the customer has confirmed they are not the end user?

Written confirmation (via e-mail or paper) is required from the customer to show they are not the end user of services.
If the customer answers “yes” to all 5 questions, Domestic VAT Reverse charge applies for all Invoices issued from 1/3/21 to their customer. In such case, the subcontractor will not charge Normal VAT on Invoice.

However, it is important that the sub-contractor displays either the VAT Rate OR VAT Amount that he is not specifically charging under Normal VAT.

Additionally, they may need to put the following note below invoice:

The following changes need to be made in Business Central OR Navision for contractors (customers) who are using sub-contractor (suppliers) services (if they are required to account for reverse charge VAT as mentioned in the conditions above):

1. Open New VAT Business Posting Group as Sub Contractor
2. Open New VAT Prod Posting Group for associated CIS Specified Services
3. Make Changes in VAT Posting Setup for combination of above two with VAT calculation Type as Reverse Charge
4. Map the above combinations in VAT statements for submission to HMRC, using Making Tax Digital as follows:
(1.) Change in Box 1: VAT due in this period on sales and other outputs (For Vat liability)
(Please note since this is domestic reverse charge VAT the liability thereof to be covered under Box 1 instead of Box 2)
(2.) Change in Box 4: VAT reclaimed in this period on purchases and other inputs (for reclaiming VAT liability mentioned in Box 1)

To summarise, the table below explains representation on VAT statement changes in Sub-Contractor (Seller) & Contractor (Purchaser) Books:

And so, contractors will start calculating the reverse charge on all purchase invoices accounted on or after the 1st of March. This will be for CIS specified services purchased from their sub-contractor and will also be accounted as a liability in the books of the contractor’s accounts.
