Contact OzCalc
Questions, corrections and advertising queries go to a real inbox. We are independent — not the ATO, a bank or an energy retailer.
Prefer to write it yourself? Use that address. We aim to reply within a few business days.

Use the form if you would rather start from a draft. It opens your own mail app — we do not run a comment server.
What to include
Reporting a wrong result
This is the most useful kind of message we get. Name the calculator, the exact inputs you used and the figure you expected instead — ideally with the source you are comparing against. That is enough to reproduce the problem. Please do not send private financial or identifying information; we do not need it to check arithmetic.
A rate or threshold is out of date
Tell us which figure and link to the authority that publishes it. Regulated figures live in versioned datasets that record their source and review date, so a correction updates every calculator and guide that depends on it. Our editorial policy explains that process.
Suggesting a calculator or a guide
Describe the calculation you were trying to do and where you got stuck. Requests that come with a real scenario are far more likely to be built, because they tell us which inputs actually matter. We do not publish a tool until it has a working result, a formula, assumptions, an example and a source.
Privacy, advertising and permissions
Privacy questions, including about analytics and advertising, are answered in the privacy policy. Advertising enquiries and requests to reproduce content beyond what the terms of use allow can go to the same address.
What we cannot help with
We cannot give you tax, financial, credit, legal or employment advice, tell you what you will be assessed or approved for, or intervene in a dispute with the ATO, a lender, a landlord or an employer. We are an independent calculator site, not an adviser or an agency — see the disclaimer. For those questions, the authority named as the source on the relevant calculator page is the right place to start.
