Capital Gains Tax (CGT) applies when you sell or dispose of an asset that has increased in value. In Australia, there is no separate CGT rate — instead, the net capital gain is added to your taxable income and taxed at your marginal rate.
When selling an investment property, the capital gain is calculated as the sale price minus the cost base. The cost base includes the original purchase price, stamp duty, legal fees, building and pest inspection costs, capital improvements, and selling costs such as agent commissions and advertising.
Share sales trigger a CGT event. The cost base is the purchase price plus brokerage fees. If you receive shares through a DRP (Dividend Reinvestment Plan), each DRP allocation has its own cost base and acquisition date. The 50% discount applies to shares held longer than 12 months.
Australian residents who hold a capital asset for more than 12 months before selling it can reduce the capital gain by 50%. This means only half the gain is added to your taxable income. Companies are not eligible for the 50% discount.
The capital gain is the sale price minus the cost base. The cost base includes the purchase price, stamp duty, legal fees, renovation costs, and selling costs (agent fees, advertising). If held over 12 months, the 50% discount applies.
Yes, your main residence (the home you live in) is generally exempt from CGT under the main residence exemption. However, if you rent it out or use part of it for business, a partial exemption may apply. The 6-year absence rule allows you to treat a property as your main residence for up to 6 years while rented.
Cryptocurrency is treated as a CGT asset. You pay CGT on the difference between what you paid for the crypto and what you received when you sold, traded, or exchanged it. The 50% discount applies if you held it for more than 12 months. Each trade is a separate CGT event.
Yes, capital losses can be offset against capital gains in the same year. If your losses exceed your gains, the net loss is carried forward to future years. Capital losses cannot be offset against ordinary income (salary, wages, etc.).
