What is CIS?
CIS (construction industry scheme) is a tax levied on contractors. Please read the HMRC guide to know if it applies to you: https://www.gov.uk/what-you-must-do-as-a-cis-subcontractor/get-paid
You can edit this through your 'Company settings'. Click into the CIS percentage setting and choose your percentage (or if you are not registered, there is an option to show this too) and click 'Save' once you've done so.
Can I edit this later?
Yes, these details can be edited at any time.
Does this get added to all invoices?
No, you have a dropdown to select which line items on the invoice need CIS against them.
Does this send across to my accounting package?
Yes, if you use FreeAgent, Kashflow or Sage Accounting and invoices with CIS enabled on Commusoft will transfer into your accounting package correctly.
