SAM20070 – Assessments: assessments within SA: relevant dates for section 86 interest purposes


The SA system will automatically compute Section 86 interest on the basis of the entries you make in the various fields in function CREATE REVENUE ASSESSMENT. These may be

  • FIRST POA - 31st January during the year of assessment
  • SECOND POA - 31st July following the end of the year of assessment
  • BALANCE - 31st January following the end of the year of assessment

If you need to record any other relevant date(s) for Section 86 interest purposes use function AMEND RELEVANT DATES.

To determine the correct relevant dates, (and the entries you should make in function CREATE REVENUE ASSESSMENT), you must consider

  • The type of assessment being made
  • The year of assessment
  • In respect of discovery, whether the assessment is for one year only, or whether assessments for consecutive years are being made
