About
Who publishes CGT Calculator, what it provides, and how its work is maintained.
Last updated: 4 August 2026
Who publishes this website
CGT Calculator is published and maintained by MoneyToolkit, an independent Australian publisher of practical financial calculators and plain-English guides.
MoneyToolkit is responsible for the calculators, editorial content, updates, and corrections on this site. We use a publisher identity so the work is accountable without requiring an individual contributor to make their personal identity public.
We are not affiliated with the ATO, a tax practice, broker, exchange, property agency, or investment provider. Advertising does not influence calculator results or editorial conclusions.
What we build
The site includes a general CGT estimator and specialised calculators for property, shares, crypto, the main-residence exemption, inherited assets, small business concessions, and carried-forward losses.
They are designed for taxpayers doing early planning or checking questions to raise with a registered tax agent.
Sources you can inspect
We prioritise Australian Taxation Office guidance, Commonwealth tax legislation, explanatory material, and published Australian resident tax rates.
Reviewed when inputs change
We prioritise review when tax legislation, ATO guidance, rates, thresholds, or calculator logic changes, or when a reader reports a possible error.
Private by design
Calculator inputs are processed in your browser. You can use the tools without creating an account or sending the values you enter to us.
How to assess our work
Read the calculator methodology for the model, assumptions, and sources, and the editorial policy for our sourcing, review, and independence standards. If something appears wrong or out of date, the corrections policy explains how to report it.
Important limitation
Capital gains tax depends on ownership history, dates, residency, asset use, cost-base records, elections, exemptions, and interactions with the rest of a tax return. Results are estimates and should be checked against records and professional tax advice.
