I have added CIS regular 20% to the invoice but it is not deducting it or showing the working out. How do I do this?

I choose the standard CIS 20% as the product, and have checked the contractor as CIS but it is not calculating or showing on the invoice. I have done this before for another company and the invoice doesn't show the calculation until you send it, but now it is not doing the calculation at all.

Hi mike.

Thank you for contacting Community.

In order for the CIS suffered to be calculated on the invoice itself, both the customer and yourself would have to be recorded as a Contractor and Subcontractor.

If you have already gone into the Customer details and ticked the 'Is a CIS Contractor' you would also need to do this on your own account as a Sub-Contractor. If you go into the Settings section by clicking the cog and go into the Advanced settings section, under CIS you will have a tick box that will allow you to record yourself as a CIS Sub-Contractor. If you tick this, and select a CIS account form the account list when raising an invoice, when you enter a total it will show the amount with a section that shows the CIS deduction.

Let me know if you have any queries. Or, if you'd like to go through this over the phone, you can call our dedicated team who will be happy to assist you. Our contact details can be found here along with our opening hours.

CIS Suffered / CIS Return

So in Quickbooks settings are already there and ready to go for CIS Suffered. The invoices we are raising are working fine and postings are going to the correct CIS GL accounts.

However, I have just run the CIS return for period ending 5th Oct and only the sub-contractor CIS deducted is showing. The CIS suffered, for invoices we have received payment for, are not.

Why is this not working?
Or do I still enter manually - is the CIS suffered purely used in Quickbooks for recording the accounting transactions and NOT to enable and calculate on the CIS return?

Re: CIS Suffered / CIS Return

Hi @sashalankshear,

The system is also calculating your CIS suffered amount. It's located on a different report, which is the CIS Suffered Summary report.


Here's how to run the report:

  1. Go to the Reports tab.
  2. In the search box, type in CIS Suffered Summary.
  3. Select the correct Report period, as well as the necessary Accounting method.
  4. Click Run report.

All things CIS-related are in this article: CIS in QuickBooks. You can find the steps on how to enable CIS, adding a contractor, and a subcontractor as well.
