⚡ Key Takeaways
- CGT is not a separate tax — it is part of your income tax. You make a capital gain or loss when you dispose of a CGT asset (sell, gift, swap, or convert to personal use). The net gain is added to your taxable income and taxed at your marginal rate. [5]
- The 50% CGT discount (for assets held 12+ months by individuals) currently halves the taxable gain — but this will be replaced from 1 July 2027 with inflation-based cost-base indexation and a minimum 30% tax rate on net gains. [1][2][4]
- The new rules only apply to gains that accrue from 1 July 2027 — transitional provisions allow gains accrued before that date to be treated under the old rules. [3][4]
- Your main residence is fully CGT-exempt — but the exemption is easy to lose by renting out part of it, using it for business, or not understanding the six-year rule when you move out and rent it. [6]
- The Parliamentary Budget Office estimates the 50% CGT discount will cost $247 billion over the next decade, with almost 60% of the benefit going to the wealthiest 1% of taxpayers. [12]
- Tax firms including Andersen, William Buck and EY report significant client activity around timing disposals before 1 July 2027 and restructuring holdings into companies or super funds. [3][8][10]
Capital Gains Tax in Australia Explained Simply: Property, Shares & Crypto (2026)
By The Fine Print editorial team | Last updated: June 2026 | 12 min read | ⚠️ Not financial advice
Capital gains tax in Australia isn’t just a line on a tax return — it quietly decides who gets rewarded for holding assets, who gets punished for selling, and who can afford to play the property and share game at all. In 2026, the rules are being rewritten in the biggest CGT reform since 1999. If you don’t understand them, you’re not just paying tax — you’re paying for someone else’s discount.📋 What’s in This Guide
What CGT Is and When It Applies
The ATO is clear: CGT is not a separate tax. It is part of your income tax. When you dispose of a CGT asset — by selling it, gifting it, swapping it, or converting it to personal use — you calculate a capital gain or loss. Any net gain is added to your other taxable income and taxed at your marginal rate (plus Medicare levy). Capital losses can be offset against gains before the discount is applied, and unused net capital losses carry forward indefinitely to offset future gains. [5]CGT applies to most real estate other than your main residence, listed shares, ETFs, managed funds, crypto assets, and business assets — unless they were acquired before 20 September 1985 (when CGT was introduced) or fall into specific exemptions. [5][6]Current Rules: Property, Shares and Crypto (Pre-2027)
The 50% CGT discount (while it lasts)
If you hold an asset for 12 months or more before selling, you currently qualify for the 50% CGT discount — meaning only half the nominal gain is included in your taxable income. This is the mechanism that has allowed property and share investors to pay dramatically less tax on long-term gains than on wage income. It applies to individuals and trusts, but not companies. [5][7]Investment property
CGT applies to rental properties, vacant land, subdivisions and improvements, former homes that become rentals, and holiday homes and second properties. The cost base for property includes the purchase price plus stamp duty, legal fees, improvement costs and other acquisition expenses — many investors under-calculate this and overpay CGT as a result. [6][5]Shares and managed funds
For listed shares and ETFs, CGT is triggered when you sell — dividends are taxed separately as income. Managed funds and ETFs often distribute capital gains to investors each year, which you must include in your tax return even if you reinvest the distribution. Forgetting these annual distributions is a common and costly mistake. [5]Crypto assets
The ATO treats most cryptocurrency — Bitcoin, ETH, and most altcoins — as CGT assets. A CGT event occurs when you sell crypto for fiat currency, swap one crypto for another, use crypto to buy goods or services, or gift crypto. Only very small personal-use crypto holdings can escape CGT; long-term crypto investments are subject to the normal CGT rules, including the 50% discount where the holding period and other conditions are met. [5]⚠️ Crypto swap trap: Many people don’t realise that swapping one cryptocurrency for another (e.g. trading Bitcoin for ETH on an exchange) is a CGT event — not just selling for dollars. Each swap is treated as a disposal of the first asset at market value on the date of the swap. If you’ve been actively trading crypto without tracking every transaction, you may have significant CGT obligations you haven’t accounted for. [5]
The Main Residence Exemption — and How to Accidentally Lose It
For most Australian homeowners, the main residence exemption is the most valuable tax break they will ever receive — it means you can sell your home completely CGT-free, no matter how large the gain, provided the rules are met. But people regularly lose partial or full exemption without realising it. [6]Common ways to accidentally trigger a partial CGT liability on your home: renting out part of it (even a spare room through Airbnb); using a meaningful portion as a registered home office or business premises; owning land over 2 hectares; and subdividing or selling part of the property separately. Each of these can convert a portion of what you assumed was a CGT-free gain into a taxable CGT event — sometimes costing tens of thousands in unexpected tax. [6]💡 The six-year rule: If you move out of your home and rent it, the main residence exemption can continue to apply for up to six years — meaning you can rent it out and still sell it CGT-free — provided you don’t treat another property as your main residence during that period. This is one of the most powerful (and most misunderstood) CGT rules in Australia. If you’re renting out a former home, or thinking about it, this rule is worth understanding in detail before you sell. [6]
The 2027 CGT Overhaul: What’s Actually Changing
The 2026–27 Budget announced the most significant CGT reform since the Howard government introduced the 50% discount in 1999. From 1 July 2027: [2][4][1]- The 50% CGT discount is replaced for individuals, trusts and partnerships with an inflation-based cost-base indexation — similar to the system that applied before 1999. You adjust your cost base for inflation, then pay tax on the real gain, not the nominal gain.
- A minimum 30% tax rate on net capital gains will apply, regardless of the investor’s marginal income-tax rate. This ensures high earners pay at least 30% on their real gains rather than using the 50% discount to convert wage-taxed income into lightly-taxed capital gains.
- The new rules only apply to gains accrued from 1 July 2027. Transitional provisions allow the gain on pre-2027 accruals to be separately calculated under the old rules — so selling a property you’ve held for years won’t mean the entire gain is taxed under the new regime.
- New builds get a choice: investors who buy qualifying new-build residential properties can choose between the old 50% discount or the new inflation-based discount with 30% minimum tax. This is designed to encourage investment in housing supply. [4][11]
⚠️ What this means for lower-income investors: The 30% minimum tax could actually hurt some investors on lower marginal rates who previously benefited from the 50% discount more than high earners did. If your marginal rate is below 30%, the new minimum tax may result in you paying more CGT than under the current system. EY and William Buck have both flagged this as a concern — it’s worth modelling your specific situation before making decisions. [9][8]
Who Wins, Who Loses, and the Fairness Debate
The Guardian’s 2026 reporting on Parliamentary Budget Office estimates sparked significant debate: the 50% CGT discount will cost $250 billion over the next decade — more than its entire first 25 years combined — with most benefits flowing to the wealthiest 1% of taxpayers and asset-rich retirees. Critics argue this is intergenerationally unfair: younger Australians without assets effectively subsidise tax breaks for older, wealthier investors. [12]AHURI’s long-standing research explains that the 50% CGT discount, combined with negative gearing, encourages investors to focus on capital gains rather than rental yields — pushing more capital into housing speculation and contributing to price inflation that prices out first-home buyers. The 2026 Budget reforms are explicitly designed to dial back this distortion, although grandfathering and new-build carve-outs mean the system continues to privilege certain forms of property investment. [7]On the investor behaviour side, tax firms report that people who understand CGT — and can afford advice — have always timed disposals strategically: selling in years with lower income, harvesting capital losses to offset gains, and carefully calculating cost bases. Those without advice sell in the wrong year, fail to apply losses, or miscalculate cost base (forgetting stamp duty, legal fees and improvement costs), leading to higher taxable gains than necessary. The 2026 reforms don’t fix this complexity gap. [3][7][5]✅ Three Moves to Stop CGT Ambushing You
Action 1: Map your CGT exposure across all assets right now
Make a simple inventory of every asset that could trigger CGT: investment properties, holiday homes and vacant land; share portfolios, ETFs and managed funds; and crypto holdings. For each, record the purchase date (to determine whether the 12-month threshold is met), the full cost base (purchase price plus stamp duty, legal fees, brokerage, and any capital improvements), and the current market value. This gives you a clear picture of your largest unrealised gains and any capital losses you could harvest. Most people have no idea of their actual CGT exposure until they receive a tax assessment — at which point it’s too late to do anything about it. [5][6]Action 2: Plan timing around the 1 July 2027 changes — with professional advice
If you are sitting on large unrealised gains on assets held for more than 12 months, talk to a registered tax agent now about whether it makes sense to crystallise some of those gains before 1 July 2027 under the existing 50% discount — paying tax now at a known rate rather than facing the new 30% minimum tax plus inflation-indexation regime. Also consider whether realising existing capital losses in 2026–27 to offset gains under the current rules makes sense. For new-build property purchases, understand the choice you’ll have between the old 50% discount and the new indexation system — run worked examples before assuming either is better for your situation. [3][8][10][1]Action 3: Use the ATO’s free CGT tools — and keep every record
Before you buy or sell anything, read the ATO’s CGT guides — they cover which assets are exempt, how to calculate cost base and adjust for improvements, and how the 12-month rule and discount apply. The guides are free, accurate and updated for the 2026 changes. More importantly, keep all purchase and improvement records for every CGT asset: property contracts, stamp duty receipts, legal fees, improvement invoices, brokerage records and crypto transaction histories. Missing records are one of the most common reasons ordinary investors pay more CGT than they legally owe — if you can’t prove your cost base, the ATO will use a lower number. [5][6]❓ Frequently Asked Questions
How does CGT work in Australia in 2026?
CGT is part of your income tax — gains are added to taxable income and taxed at your marginal rate. Hold an asset 12+ months and you currently get the 50% discount (only half the gain is taxable). Losses offset gains before the discount is applied and carry forward indefinitely. [5]What is changing with CGT from 2027?
From 1 July 2027: the 50% discount is replaced with inflation indexation + a 30% minimum tax on net gains. Only applies to gains accruing from that date — pre-2027 value is calculated separately. New-build property investors get a choice between the old and new system. [2][4][1]Is my home exempt from CGT?
Generally yes — but the exemption can be partially lost by renting out rooms, using it as a business premises, or owning land over 2 hectares. The six-year rule can preserve the exemption for up to six years after you move out and rent it, provided another property isn’t treated as your main residence. [6]Does CGT apply to crypto in Australia?
Yes — the ATO treats most crypto as CGT assets. CGT is triggered when you sell for fiat, swap cryptos, use crypto to buy goods, or gift it. Every transaction needs to be tracked. The 12-month discount applies if eligible. Only very small personal-use holdings may escape. [5]⚖️ The Fine Print Verdict
Capital gains tax in Australia has always quietly rewarded the people who understood it — and punished the people who didn’t. The 50% discount gave high-income investors a way to convert wage-taxed income into lightly-taxed capital gains that most ordinary Australians never accessed. The 2027 reforms are trying to fix that — but with grandfathering and new-build carve-outs, the system still picks winners. Before 1 July 2027, if you have significant unrealised gains, you have a decision to make: crystallise under the old rules, or hold under the new ones. That decision is worth getting advice on. After 2027, the rules will be different — but the principle will be the same: those who understand them will pay less.
👉 Map your exposure. Know your cost bases. Keep your records. And if you’re sitting on large gains, get advice before 1 July 2027.
