We are not a byline site — 89+ calculators are maintained as a team, not published under one person's name. So instead of a founder's reputation, here is the actual process: where our figures come from, how often we check them and what happens when we get one wrong.
ATO rates on this site were last verified against official source pages on 2 August 2026. This date updates automatically — see "How we check rates" below.
Every rate, threshold or figure on this site traces back to a government or official regulator source — never to a secondary summary or another calculator site. We link to the source on the page it appears so you can check it yourself.
A scheduled check runs weekly against the official ATO source pages our income tax engine is built from. If a rate has drifted from what we publish, the check fails loudly rather than silently — it opens an internal issue rather than letting the site go stale. On a pass, the verified date shown across the site (the badge above, and the one under every calculator) updates automatically. Data-driven pages built on ABS, RBA and APRA figures refresh on their own published release cadence (monthly or quarterly, depending on the series) rather than a fixed schedule, since that is how often the underlying data actually changes.
Behind the 89+ calculators is a shared library of maths, not one-off page logic — the same tax engine, for example, powers salary, pay rise, redundancy and dozens of other tools, so a fix in one place fixes all of them. Every engine ships with automated tests that check it against known, worked examples before any change reaches the site. Where we have found a real defect during development — a wrong income test, a bracket applied per-child instead of per-family — we have written it up, fixed it and added the test that would have caught it. We would rather publish that history than pretend it does not happen.
Tax law changes, sometimes mid-year, and we are maintaining a large surface area. If a figure looks wrong, tell us at hello@ozfinancehub.com.au with the page and what you expected — we treat every report as a possible defect until we have checked the source ourselves, not as a support ticket to close. Real corrections get fixed, tested and shipped; we do not quietly edit a number and move on.
This process exists independently of how the site is funded — see how we make money for what pays for it, and our disclaimer for what this site is not: financial, tax, credit or legal advice.
