Prefer email?

This is a personal project operated by Chas Walker. Emails are checked regularly but response times are not guaranteed.

Reporting a calculation error?

Please include as much detail as possible so the issue can be reproduced and fixed quickly:

The salary or income amount you entered
Which options were selected (HECS, private health, residency, tax year)
What result the calculator showed
What result you expected, and why (e.g., a link to the ATO page or your payslip)

Response times

This is a personal project run in spare time. We aim to respond to emails within a few days, though this is not guaranteed. Calculation errors affecting accuracy are treated as high priority and addressed as quickly as possible.

Please note: We are not able to provide personalised tax advice. For questions about your specific tax situation, please contact a registered tax agent or the ATO directly at ato.gov.au or call 13 28 61.
