ChangeGPS Capital Gains Tax assesses all four Small Business CGT Concessions under Division 152 of the Income Tax Assessment Act 1997 (ITAA 1997). The 15-Year Exemption allows a full exemption from capital gains tax where a business asset has been continuously owned for at least 15 years and a Significant Individual is retiring or permanently incapacitated. The 50% Active Asset Reduction reduces the capital gain by 50% where the asset has been an active asset for the required period. The Retirement Exemption excludes up to $500,000 of capital gains from income tax over a stakeholder's lifetime (amounts must be contributed to superannuation if the stakeholder is under age 55). The Roll-over Relief allows the capital gain to be deferred by replacing the asset or contributing the proceeds to superannuation. ChangeGPS CGT models all four concessions and assesses eligibility automatically based on the information you enter.
