HMRC have made changes to how VAT is processed in the construction sector from 1 March 2021, introducing domestic VAT reverse charge. This article will provide an overview of these changes and how they apply to you.

This applies to SBCA users where construction services are supplies and any goods are supplied in conjunction.

The new rules imposed by HMRC mean that those supplying construction services, that fall within the scope of the CIS, to a VAT-registered contractor, no longer account for the VAT themselves.

On 1 March 2021, SBCA introduced a domestic reverse charge functionality to support this legislation (and provide for some other use-cases). Please also consult the guidance issued by Sage Accounting on the correct treatment of these changes.

AutoEntry support for this functionality was released on 9 March 2021. In AutoEntry, simply:

  1. Re-sync your tax codes to obtain the two new "Domestic reverse charge" codes - for the Standard and Reduced rates respectively (for a note on re-sync'ing data see here), and then

  2. Select the appropriate new tax code when coding up your invoice e.g.

Note that if either the invoice is dated pre-1 March, or it involves a customer or supplier that does not use the new VAT reverse charge in SBCA (i.e. with the new "VAT Reverse Charge" tickbox disabled), then a warning message will display on attempting to publish e.g.

Lastly, if you attempted to publish an invoice dated from 1 March involving a customer or supplier that uses the VAT reverse charge in the week between SBCA releasing their functionality (1 March) and AutoEntry support for it being released (9 March), then you will have received the following error:

1.base - VAT reverse charge cannot be applied

In this event, simply re-syncing your company data, unpublishing the invoice and selecting the new tax code that is now available in AutoEntry will allow you to publish the invoice correctly.
