Understanding Capital Gains Tax in Australia: A Complete Guide

Capital gains tax in Australia is not a separate tax - it is part of your income tax. A capital gain is added to your assessable income in the year the CGT event occurs:

• CGT assets: Shares, units in managed funds and ETFs, investment property, cryptocurrency, options, rights, and most other property - anything that can generate a gain on disposal
• CGT event A1: The most common CGT event - disposal of an asset (sale, gift, destruction) triggers assessment in the income year the contract is signed, NOT when settlement occurs
• Contract date rule: If you sign a contract to sell an investment property on 25 June 2025 but settlement occurs on 20 August 2025, the gain is assessed in the 2024-25 income year - this is critical for tax timing
• Capital gain calculation: Proceeds minus cost base = gross capital gain; if held 12+ months, apply 50% discount = net capital gain added to assessable income
• Capital loss treatment: Capital losses can only be offset against capital gains (not ordinary income); excess losses carry forward indefinitely; apply to current-year gains first, then reduce discountable gains before non-discount gains
• Tax rate: CGT is taxed at your marginal rate - there is no separate CGT tax rate; at 47% (including Medicare levy) top rate with 50% discount, the effective CGT rate is 23.5%
• Market value substitution: If you dispose of an asset below market value (gifting to a family member), the ATO deems proceeds to be market value - you cannot gift to avoid CGT

The cost base reduces your capital gain - getting it right can save significant tax. Many investors understimate their cost base by forgetting allowable inclusions:

• Element 1 - Acquisition cost: What you actually paid for the asset including brokerage; for gifted assets, market value at time of gift
• Element 2 - Incidental costs of acquisition: Stamp duty on property purchase, conveyancing fees, property inspection costs, legal fees for the transaction
• Element 3 - Ownership costs: Only for non-rental property (not typically applicable to investment property); includes council rates, insurance on vacant land
• Element 4 - Capital improvements: Renovation costs on investment property that are capital in nature (new kitchen, extension) - not the same as repairs and maintenance (which are immediate deductions)
• Element 5 - Incidental costs of disposal: Agent's commission on sale, legal fees, advertising costs for property sale - these reduce the gross proceeds, lowering the gain
• DRP reinvestments: Each distribution reinvestment creates a separate cost base parcel at the unit price on reinvestment date - missing these parcels inflates your assessed gain; Sharesight and the ATO's myTax pre-fill captures these
• CGT-reduced cost base: For calculating capital losses (not gains), ownership costs (Element 3) are excluded - prevents artificial loss inflation
• Indexation method (pre-1999 assets): Assets acquired before 21 September 1999 and held for 12+ months can use CPI indexation of cost base to September 1999 as an alternative to the 50% discount - useful only when inflation-adjusted cost base exceeds half the gain

The discount method - halving the capital gain for assets held 12 months or more - is the most widely used CGT concession in Australia. Understanding its boundaries is important:

• Eligibility: Individual taxpayers, trusts distributing to individual beneficiaries, and complying superannuation funds (which get a 1/3 discount instead of 50%); companies do NOT get the discount
• 12-month test: Counted from the date of acquisition contract to the date of disposal contract - not based on settlement dates at either end
• Partial ownership period: If you acquired an asset in stages (e.g., exercising options), only the portion held 12+ months qualifies for the discount
• Superannuation funds: SMSFs and APRA funds pay 10% effective CGT rate (15% headline minus 1/3 discount) on gains from assets held 12+ months - significantly better than the 23.5% effective rate at the top marginal rate outside super
• Trust distributions: If a trust distributes a discounted capital gain, the beneficiary grosses it up (doubles it), applies the discount, and includes the net gain in their income - the trust preserves the character of the gain for individual beneficiaries
• Non-residents: Foreign tax residents do NOT get the 50% discount on Australian taxable property (direct real estate, shares in companies whose value is principally Australian real property) acquired after 8 May 2012
• Carry-forward losses offset sequence: Current-year capital losses reduce gains before you apply the discount - i.e., you offset losses against non-discountable gains first to maximise the discount applied to the remaining gain

Your principal place of residence is generally exempt from CGT - but the rules are more complex than most people realise:

• Full exemption conditions: The property must be your main residence for the entire ownership period, must not be used to produce income, and must be on land of 2 hectares or less
• Absence rule: If you move out of your home and rent it, you can treat it as your main residence for up to 6 years (if you have another main residence) - this is a powerful strategy that can shelter years of capital gain
• Partial exemption - rental period: If the property was your main residence for part of your ownership, the exempt proportion is: (days as main residence / total days owned) × total gain
• Moving into an investment property: If you buy an investment property and later move in, you can elect to treat it as your main residence from the date you moved in - gains before that date are taxable (less any depreciation recaptured)
• Two-property overlap: When buying a new home before selling the old one, both can be treated as your main residence for up to 6 months - the overlap must not exceed 6 months
• Death and inherited property: A 2-year period applies for beneficiaries to sell an inherited property and claim the main residence exemption; after 2 years, partial exemption applies based on the deceased's use
• Depreciation recapture: If you claimed building allowance (Div 43) on an investment property and later sell, the depreciation claimed reduces your cost base - increasing your taxable gain; this is NOT the same as recapture in some other countries but the mathematical effect is similar

Assets acquired before 20 September 1985 are 'pre-CGT' and entirely exempt from CGT on disposal. Inherited assets have their own special rules:

• Pre-CGT date: 20 September 1985 is the cut-off - assets acquired before this date are not subject to CGT when disposed of; gains are entirely tax-free
• Pre-CGT company shares: If a company holds pre-CGT assets and you later sell shares in that company, the company's underlying pre-CGT assets retain their exempt status - but post-CGT company shares are taxable
• Inherited pre-CGT assets: If you inherit a pre-CGT asset, you take it at its market value as at the date of death as your cost base; any subsequent gain from that value is subject to CGT under your ownership
• Inherited post-CGT assets: You step into the deceased's shoes - you inherit their original cost base and acquisition date; if the deceased held the asset 12+ months, you can apply the 50% discount immediately on sale
• No CGT at death: Australia has no estate duty or death duty - CGT is only triggered when you actually sell the inherited asset (deferred, not forgiven)
• Market value at death: For post-CGT assets where the deceased acquired after 20 Sept 1985, the beneficiary takes market value at date of death as the cost base - not the original acquisition price
• Spousal rollovers: Assets transferred to a spouse on breakdown of marriage or de facto relationship roll over at the original cost base - CGT is deferred until the receiving spouse later sells

There are several legitimate, ATO-accepted strategies to reduce your CGT liability - none of these are avoidance schemes:

• Hold for 12+ months: The simplest and most effective strategy - the 50% discount halves your tax on the gain
• Time disposals across financial years: If you're selling in June, consider whether delaying to July reduces your marginal rate (lower income year ahead, or deferring tax 12 months)
• Harvest losses: Sell underperforming assets before 30 June to realise losses that offset gains from that year - then repurchase after 30+ days if you still want the exposure (to reduce wash-sale risk)
• Super as a low-CGT environment: Assets held inside super pay 10% effective CGT (with discount) vs up to 23.5% outside - consider which assets are best held where
• Donate appreciated assets: Donating listed shares or property to a DGR charity uses the cost base as the deemed proceeds - you receive a charitable deduction equal to market value while the asset's embedded gain is not taxed
• Small business CGT concessions: For active business assets with net assets under $6 million - four concessions can reduce or eliminate CGT on business sale proceeds (15-year exemption, 50% active asset reduction, retirement exemption, rollover)
• Instalment contracts: Spreading the sale proceeds over two financial years (instalment contract with payment in year 1 and year 2) spreads the capital gain across two income years - reducing the marginal rate impact in each year
