CGT Toolkit · Free · Educational

Tools for Australian CGT and business valuation matters.

Eight free tools to help you understand whether you need a valuation, identify what kind of CGT event you’re dealing with, and pre-check eligibility for the small business CGT concessions. Educational only — confirm with your accountant before acting.

Important: Tools in this toolkit are educational only and do not constitute tax or legal advice. Prismi is not a registered tax agent. We do not provide tax advice. For tax matters, consult your accountant or a registered tax adviser. For independent business valuations, we are happy to help.

A note on how these tools work

Each tool walks you through a structured set of questions and returns an educational output — a diagnostic, an indicator, or an indicative range. None of the tools output a specific tax-payable figure. None of them constitute advice. Every tool ends with a recommendation to consult your accountant or tax adviser before acting, and a path to discuss the valuation aspect with us if relevant.

We built this toolkit because the line between “needing a market valuation” and “not needing one” is often unclear to business owners, and because the supporting evidence required for CGT events is poorly understood. The tools help you orient. The work — when you need it — happens in the engagement.
