How does tax & government work in Australia?
Our tax & government calculators apply the same formulas, brackets and buffers that banks and the ATO use internally. We update assumptions weekly from RBA, APRA and ATO releases. Run the math →
Are the numbers reliable?
Yes—every calculation is auditable. We show the working, and the rates come from what every bank publishes under the Consumer Data Right, the RBA cash rate and ATO 2026 brackets. They're estimates, not advice. Run the math →
Do I need to sign up?
No. There are no signups and no upsells. The calculators run in your browser — only a question you choose to send the assistant leaves it. We earn nothing from any bank or product. The math is the product. Run the math →
What can the AI assistant do?
Ask questions in plain English. The assistant runs the calculators live, cites the formulas, and explains the result in your situation—linking back to the underlying tools. Run the math →
