Capital Gains Tax (CGT) is a ChangeGPS app that helps accountants and tax advisors calculate capital gains on the disposal of business assets and assess eligibility for the four Small Business CGT Concessions under Division 152 of the Income Tax Assessment Act 1997 (ITAA 1997). The app guides you through a structured five-step wizard, automates the eligibility assessment, allows you to model multiple concession scenarios side by side, and generates a professional CGT advice report for your client.
CGT is available in Australia.
What Capital Gains Tax does
The CGT app calculates the capital gain or loss on the disposal of a business asset based on the cost base, sale price, and relevant dates — with real-time recalculation as you enter data.
The app assesses eligibility for all four Small Business CGT Concessions under ITAA 1997 Division 152 — the 15-Year Exemption, the 50% Active Asset Reduction, the Retirement Exemption, and Roll-over Relief — through a structured eligibility questionnaire.
CGT models multiple concession scenarios side by side, allowing you to compare the after-tax outcome of applying different concessions or combinations of concessions to the same capital gain.
The app generates a professional CGT tax advice report that includes the capital gain calculation, concession eligibility assessment, and scenario comparison.
Who should use Capital Gains Tax
The CGT app is designed for accountants and tax advisors whose clients are selling or have sold a business asset that may be eligible for Small Business CGT Concessions. This includes clients who own a business through an individual, company, or trust structure and are disposing of active assets such as goodwill, business real property, or shares in a small business company.
The app is also valuable in pre-sale planning — modelling scenarios before a transaction completes to identify which concessions are available and what the after-tax proceeds will be.
