Corrections & updates log
A public record of substantive changes to this site's calculators and content. Corrections fix something we got wrong; updates track routine maintenance such as annual rate changes. Minor copy edits are not logged.

- correction
Medicare levy surcharge calculation base corrected
We previously applied the Medicare levy surcharge rate to the broader income amount used to select the surcharge tier. That could overstate the surcharge in salary-sacrifice scenarios. The broader income-for-MLS-purposes amount now selects the tier, while the calculator applies the rate to taxable income within the amounts it models.
Affected: Income Tax Calculator, MLS Guide, Methodology
- update
2026–27 income-tax settings completed
Added the 15% resident tax bracket for income from $18,201 to $45,000, the $1,000 standard work-related deduction, updated Medicare levy low-income settings, indexed MLS thresholds, and 2026–27 HELP repayment bands. The 2027–28 configuration also records the legislated 14% bracket and Working Australians tax offset.
Affected: Income Tax Calculator, $1,000 Deduction Guide, Tax Brackets Guide
- correction
2025–26 HELP calculation and MLS thresholds corrected
Corrected the combined income-tax estimate to use the 2025–26 marginal HELP repayment calculation. We also replaced outdated MLS bands with the 2025–26 thresholds used to determine the surcharge tier.
Affected: Income Tax Calculator, HELP Repayments Guide, MLS Guide
Report a possible error
Email [email protected] with the page URL and a short description of what appears incorrect. For calculator issues, include the inputs needed to reproduce the result, but do not send tax file numbers, payslips, identity documents, employer records, bank details, or complete tax returns.
A link to an official source, legislation, regulator guidance, or other supporting evidence helps us investigate more quickly.
What happens next
- 1
Reproduce and verify
We check the page, calculation path, cited source, and relevant assumptions.
- 2
Assess materiality
We distinguish a factual or calculation error from a reasonable difference in assumptions or circumstances.
- 3
Correct the source and explanation
If a material error is confirmed, we update the calculation or text and review related pages that may rely on the same information.
- 4
Record meaningful changes
We update the page review date when the correction materially changes a result, threshold, benchmark, or conclusion.
A different estimate is not necessarily an error
A final tax assessment depends on residency, income sources, deductions, offsets, private health cover, family circumstances, reportable amounts, and other facts a general calculator cannot fully capture.
Privacy when reporting
