There still seems to be a great deal of confusion about VAT in the construction industry.
I often have to send invoices back to subcontractors for amendment because the wrong VAT code has been applied. Usually causing a VAT headache for them in the process.
So here it is in the simplest terms I can muster.
If you are a subcontractor who is not VAT registered, you can crack on and ignore this post. It doesn’t apply to you.
If you are a VAT registered subbie working for another contractor, here’s what you need to do:
First, ask the contractor if they are VAT registered.
If they aren’t, invoice them in the normal way, charging the applicable VAT rate (0%, 5% or 20%) on your invoice.
If the contractor is VAT registered, then the following applies:
Check with the contractor whether the project you’re working on is zero-rated, reduced rate, or standard rate for VAT.
For zero-rated projects, invoice in the normal way.
For reduced rate (5%) and standard rate (20%) projects, do not add VAT to your invoice. Instead, show the VAT as DRC 5% or DRC 20% and add a line stating: 'Domestic Reverse Charge Applies.'
Using accounting software such as Xero (there are many others) will help ensure your invoices are correct, look professional, and that your VAT returns are reported to HMRC properly.
Additional points to note:
If the job falls under DRC, it applies to the whole supply, including materials you are supplying as part of the job. You do not charge normal VAT on the materials. The reverse charge applies to both labour and materials together.
Do not confuse DRC VAT and CIS Tax. They are completely separate schemes.
Getting VAT wrong in construction is expensive and time consuming to fix. If you’re serious about running your subcontracting business properly, make sure your invoicing process is set up correctly from the start.
