Debt and return pursuit: CIS: in-year and end-of-year process: identifying errors on returns

When you have checked the end of year tab and identified that the return is not finalised it may be that there is an error on the return.

On the Returns tab:

  • select the return by selecting the check box
  • select ‘Return details’ button
  • check the subcontractor ‘Total deducted field’.

If this shows an unreadable field, you will see XXXX instead of the amount.

If the contractor has included a minus figure (this is also classed as an unacceptable field), you will see the minus figure.

The CIS Team in Newcastle will hold an exception for these returns and will correct the error.

If you identify an error on the return

If the scheme is for less than 25 subcontractors and the correction is straightforward, ask the contractor to ring the CIS Helpline 0300 200 3210.

If the scheme has 25 subcontractors (a large scheme) or the corrections are complex, ask the contractor to write to CIS Team in Newcastle at:

National Insurance Contributions and Employers Office
HM Revenue and Customs
United Kingdom

If we already have details in writing, forward this to the CIS Team in Newcastle by eForm to ‘NICEO PAYEmp EOY’.


  • use RECORD ACTIONS to record for example Tele Call/Correspondence/Clerical
  • select Other
  • make a Further Information note
  • set a new BF date for 14 days later.

When the correction has been processed on CIS, IDMS will receive an update.
