What we got wrong, and when we fixed it.
Errors in tax figures matter, so we log them publicly rather than editing quietly. Every correction below shows the date, what was wrong, and what it was changed to. If you have found a mistake, please tell us.

A confirmed error in a published tax figure is fixed as a priority and logged on this page the same day.
The most useful things to include are: the page URL, the figure you believe is wrong, what you think it should be, and the ATO or Fair Work page you're working from. Every report is checked against the primary ATO or Fair Work source before anything changes.

Correction | The Medicare levy low-income threshold, corrected again — this time
against the legislation.
The single low-income threshold for 2025–26 is $28,011, and the phase-in limit is $35,013. The same pair applies to 2026–27. Authority: Treasury Laws Amendment (Delivering an Efficient and Trusted Tax System) Act 2026, Schedule 5 — item 5 substitutes $28,011 for $27,222, item 3 substitutes $35,013 for $34,027, and item 14 applies the Schedule to "assessments for the 2025–26 year of income and later years of income". This supersedes the entry below, which moved the 2025–26 threshold the wrong way earlier the same day. |
| 15 Aug 2026 | Correction SUPERSEDED |
The Medicare levy single low-income
threshold for 2025–26 was stored as $28,011 — the 2026–27 figure.
Corrected to $27,222.
This entry was wrong and is retained only for the record. It was based on secondary tax commentary that dated the increase to 2026–27. The amending Act says otherwise: the increase applies from 2025–26. The threshold was returned to $28,011 the same day — see the entry above. What we changed as a result. Medicare low-income thresholds are routinely amended retrospectively, so summary pages describe the pre-amendment position for months. Our sourcing rule for these figures is now the amending Act on legislation.gov.au, not commentary and not a summary page. The threshold in our data file carries that citation inline. Who was affected. Only visitors who manually selected the 2025–26 financial year in Advanced options, with a taxable income between $28,011 and about $35,013, during roughly six hours on 15 August 2026. They would have seen a Medicare levy of up to about $78 that was not payable. The default 2026–27 year was correct throughout. |
| 15 Aug 2026 | Update | The Medicare phase-in limit is now taken from the statute ($35,013) instead of being derived as threshold ÷ 0.8 ($35,013.75). Parliament rounds the limit down to whole dollars, which leaves a deliberate step of about six cents at the limit. We now implement the Act rather than the tidier arithmetic, and the test suite pins the step so it cannot be silently "fixed". |
| 15 Aug 2026 | Correction | The Low Income Tax Offset taper returned a fractionally negative value at exactly $66,667, which added about half a cent of tax instead of nothing. Now clamped at zero. |
| 15 Aug 2026 | Correction | The redundancy calculator displayed the label "ETP tax to $260k cap" while correctly applying the $270,000 cap for 2026–27. The label now reads the cap from the data for the selected year. |
| 15 Aug 2026 | Correction | The redundancy module was internally labelled as financial year 2025–26 while carrying 2026–27 figures. Both financial years are now available and correctly labelled, with 2025–26 values ($13,100 + $6,552 per year, $260,000 ETP cap) added. |
| 15 Aug 2026 | Update | Employer Super Guarantee is now capped at the maximum contribution base, which became an annual $270,830 from 1 July 2026 under payday super. Salaries above that previously over-stated employer super. |
| 15 Aug 2026 | Update | Removed an on-screen note describing the 2026–27 Medicare levy thresholds as provisional placeholders. The indexed 2026–27 threshold ($28,011) is published, so the note was no longer accurate. |
| 15 Aug 2026 | Update | Structured data removed from two pages that declared themselves to be applications without containing a calculator. One (second job) now has a working calculator; the other (pay by state) is now correctly marked up as a guide. |
How we classify changes
- Correction — a figure or calculation was wrong and someone could have been misled. Logged with what it was and what it became.
- Update — a figure changed because the law or an indexed threshold changed, or because we added detail that was previously missing.
- Clarification — the number was right but the wording was ambiguous.
- Superseded — an earlier entry on this page turned out to be wrong. It is struck through and kept, never deleted, with an explanation of what replaced it and why. A change log that quietly edits its own history is worth nothing.
