As of today (1 Oct), the ATO has (been forced to) dropped card payment fees to 0%, meaning you can pay your tax bill or ATO debt using a credit card without eating any transaction surcharges.
This creates a short 2-month window to harvest reward points/frequent flyer points on tax payments effectively for free before the ATO officially stops accepting credit card payments altogether on 30 November 2026.
The ATO page has been updated to show:
Card payment fee
Card payment fees do not apply to payments.
Happy to be corrected if I'm missing something.
This should also apply to other gov agencies if they're still accepting credit card payments.
Mod 9/10: Deal extended until 30 June 2027.
Treasurer Jim Chalmers has delayed the Australian Taxation Office (ATO)’s planned credit card payment ban until June 30, 2027, following intense backlash from small businesses and industry groups


This is in line with RBA removal of credit surcharge from 1 October. It applies to all businesses. Whether it will reduce cost or not is debatable.
