COM95015 - Payments: quarterly instalment payments: interest

Clerical Interest indicator (CII)

The ‘clerical interest’ indicator (CII) is set to instruct COTAX not to calculate and charge late payment interest automatically. Setting CII to 'Y' also inhibits automatic repayment, reallocation and the issue of payment applications.
You can set CII on an Accounting Period (AP) where the pursuit status is RFI, LA or LA-ENF using functions RAPP (Revise AP Pursuit) or MAPS (Maintain AP Signals).


COTAX sets CII where any one of the following apply:

  • a clerical interest charge is raised using function RMIC (Raise Manual Interest Charge)
  • an ACT or loss carry-back claim results in repayment and/or reallocation
  • relief is given under Section 458 Corporation Tax Act (CTA) 2010 where a loan, or part of it, has been repaid

Where CII is set, the total interest accrued to date shown in function VPPD (View Payment and Posting Details) on screen COT215C is either the amount charged or nil.

Credit/debit interest indicator (CDII)

The ‘credit/debit interest’ indicator (CDII) is set on quarterly instalment payment cases to instruct COTAX not to calculate and charge credit and/or debit interest automatically.
Setting CDII to ‘Y’ causes the Accounting Period (AP) to be made RFI or LA and also inhibits automatic repayment and reallocation.
You can set CDII on an AP where the pursuit status is RFI, LA or LA-ENF using functions RAPP (Revise AP Pursuit) or MAPS (Maintain AP Signals).
