Corporation Tax self-assessment (CTSA): the payment obligation: late payment interest

TMA70/S87A applies to late payment of CT.  Under Section 87A, interest runs from the normal due date until payment.

See CTM92220 onwards for the interest consequences of claims to carry back certain losses.

Interest on tax charged by an assessment made to recover:

  • an over-repayment of tax (and/or an overpayment of repayment interest) under FA98/SCH18/PARA52
  • an overpayment of tax credit (and/or an overpayment of repayment interest on it) (under CTA2010/S1110)
  • runs from the date the repayment being recovered was made until payment.

For the effect on late payment interest under CTSA of a claim under CTA2010/S458 see CTM98240.
