As per attached ATO in regard to MCB is $270,830, will Chris 21 update to the nearest $10 multiple so it's exactly $32500 for high income earners in the TXP screen. (under maximum super contribution base)
If we manually calculate 270830 * 12% = $32499.60 however as per ATO it should be $32500. Please let us know.
FYI. Attachment reads:
How the maximum contribution base is calculated
The maximum contribution base for a financial year is calculated using the following formula (rounded down to the nearest $10 multiple):
Concessional contributions cap × 100 ÷ charge percentage
The concessional contributions cap is the basic concessional contributions cap for the financial year in which the payment is made. From 1 July 2026, the concessional contributions cap is $32,500.
The charge percentage is the super guarantee rate, which is currently 12%.
Therefore the maximum contribution base for 2026–27 is:
$32,500 × 100 ÷ 12 = $270,830

Hi Team,
Any update on this?
Hi and thank you for your query.
The ATO has recently confirmed that using $32,499.60 (rather than rounding to $32,500) is acceptable for super contribution calculations based on the MCB. No system adjustment is currently required to round this to the nearest $10 multiple.
Thanks Christelle. Could you please provide the source, as I can't seem to find that on ATO site.
Hello and thank you for your query. The ATO’s guidance on the maximum contributions base guidance can be found here:
https://www.ato.gov.au/businesses-and-organisations/super-for-employers/paying-super-on-payday/what-payments-are-qualifying-earnings/maximum-contributions-base
It explains how super guarantee applies once an employee’s qualifying earnings reach the annual cap.
In the ATO example, Michael’s qualifying earnings reach the maximum contributions base during the year. Super is therefore only calculated up to that cap, not on the full amount paid after the cap has been reached.
In simple terms, once Michael’s qualifying earnings reach the annual maximum contributions base, no further super guarantee is required on earnings above that cap, unless another obligation applies, such as an award, enterprise agreement or employment contract.
