Editorial Policy
Sources
Every rate, threshold, taper formula, surcharge tier, and commencement date on this Site is verified against the administering revenue office's own published material or the legislation itself. The eight sources are:
- Revenue NSW (NSW)
- SRO Victoria (VIC)
- Queensland Revenue Office (QLD)
- RevenueWA (WA)
- RevenueSA (SA)
- Tasmanian Revenue Office (TAS)
- ACT Revenue Office (ACT)
- NT Revenue (NT)
No statutory section pinpoint is published unless it has been opened and verified. An Act name alone is acceptable where a pinpoint could not be confirmed.
Verification cadence
Each jurisdiction is verified quarterly and following each state and territory budget. Verification dates are published beside every figure on the rate table and on each jurisdiction page, with a link to the source. The full sourcing and verification standard is set out on our methodology page.
One source of truth
Every figure that appears in prose, tables, FAQs, schema, PDF exports or metadata is interpolated from the rate registry (FY_RATE_REGISTRY). No hardcoded tax figures exist in components or content files. Worked examples are generated by calling the calculation engine, so the example and the calculator can never disagree.
Not tax advice
eHealth Systems Pty Ltd is not a registered tax agent and does not provide tax advice. The calculators produce estimates for discussion with a registered tax agent or specialist adviser. See our disclaimer.
Correction process
If you report a suspected error, we will check it against the administering revenue office's published material. Confirmed corrections are published with a date beside the corrected figure and noted on the rate changes log where applicable. Expected turnaround for a confirmed correction is 5 business days.
No fabricated trust signals
This Site publishes no ratings, review counts, user counts, testimonials, or “trusted by X” claims. Trust is established by publishing sources, verification dates, and the correction process above.
