Debt and return pursuit: CIS: the CIS computer system

CIS computer system

The CIS computer system is browser-based which allows contractors and subcontractors access to the new system and will bring with it an increased use of the e-channel.

The system can be used to:

  • authenticate CIS customers to ensure they are who they say they are
  • verify subcontractors to find out the appropriate rates of tax deduction (it’s mandatory to do this online from 6 April 2017)
  • correct any errors on the monthly return
  • view customer records
  • log and capture returns
  • amend CIS customer details.
