I would like to clarify how the 85% rule applies to PAYG instalment variations and potential General Interest Charges (GIC).


My Situation:

  • Annual salary: $140,000 (PAYG withholding by my employer: ~$33,138)
  • Interest income for the year: $3,660
  • ATO PAYG instalment issued: $577 per quarter (based on last year’s notional tax: $2,178.25)
  • I'm Considering varying PAYG instalment to $0

I understand that if my varied PAYG instalments are less than 85% of the total tax payable, I may have to pay a GIC on the shortfall, as mentioned here: How to vary your PAYG instalments | Australian Taxation Office [link replaced by moderator]


I'm a bit confused about this rule.


If my total tax payable for the year is ~$34,492 (for salary + interest + medicare), and my employer already withholds ~$33,138 (which is more than 85% of my total tax payable), does this mean I will not have to pay a GIC for varying my PAYG to $0?


Would appreciate any clarification from the ATO. Thanks!

Hi

It is calculated just on the 'instalment income' which is your gross business and investment income (i.e. doesn't include your salary and wages).
