CIS marker in Customer Record

Hello Oil234, Essentially when you tick that box you are recording that is a contractor when you tick the box it will ask you to enter more information such as the utr number. When  you are receiving money from a contractor, once ticked if you select the contractor from the top of the page on the invoice  QuickBooks will use your CIS rate to calculate the CIS to deduct (CIS suffered). If you're charging for materials on this job, you can add these too. More information on CIS IN QuickBooks can be found here

Thanks for your reply.  I should have stated in my original question that we have gross CIS status, so is there any point in ticking the box if no tax will be deducted from payments we receive?  

However, now I am wondering whether this box needs to be ticked for the upcoming VAT reverse charge to work correctly?

Hello Oil234, 

So having the box ticked doesn't mean that the CIS is automatically calculated, you would still have to use the relevant CIS accounts on the bill.

So I don't think there is any point marking a customer as CIS if we are gross paid, but you haven't answered my question as to whether this needs to be ticked for the upcoming VAT Reverse Charge for CIS change from 1st March?

 Hello Oil234, they don’t have to be a CIS customer for you to use the RCCIS code. The RCCIS VAT code works independently of CIS deductions.
