CGT 50% discount deadline — 2027 reform for Australian investors

What Is the CGT 50% Discount?

The Capital Gains Tax (CGT) 50% discount is a concession provided by the Australian Taxation Office (ATO) that allows eligible investors to reduce the taxable portion of a capital gain by half. In practical terms, if you sell an asset and make a $100,000 gain, only $50,000 is included in your assessable income — potentially saving you tens of thousands of dollars depending on your marginal tax rate.

This concession was introduced as part of the Ralph Review reforms in 1999, replacing the previous CPI indexation method that adjusted the cost base for inflation. For more than two decades, it has been a cornerstone of long-term investment strategy for everyday Australians — rewarding patient, buy-and-hold investors over short-term traders.

Who Is Eligible for the CGT 50% Discount?

To qualify for the CGT 50% discount, you must satisfy two key conditions simultaneously:

1. Hold the asset for at least 12 months
The ATO’s definition of ’12 months’ is more precise than most investors realise. You must exclude both the day you acquired the asset and the day you sold it from your count. This means the actual minimum holding period is 367 days (or 368 days in a leap year). Mark this in your records carefully — selling even one day too early disqualifies you entirely from the discount.

2. Be an Australian resident for tax purposes at the time of the sale
The discount is only available to Australian tax residents. Foreign residents who acquired assets after 8 May 2012 are generally not entitled to the concession. Former Australian residents may be eligible for a partial discount based on the proportion of time they held the asset while a resident.

Who can access the discount:

  • Individual investors
  • Partnerships
  • Trusts
  • Self-managed super funds (SMSFs) — though at a reduced rate of 33.33%

Who cannot access the discount:

  • Companies — corporations are excluded from the CGT discount entirely and must use a cost base approach instead.
Which assets qualify for the CGT 50% discount in Australia

Which Assets Qualify?

The 50% CGT discount applies to a broad range of investment assets, including:

  • ASX shares and managed funds — among the most common assets Australian investors hold
  • Exchange-Traded Funds (ETFs) — whether tracking the ASX 200 or international indices
  • International shares — including US stocks held directly
  • Investment properties — residential and commercial
  • Cryptocurrency — the ATO treats crypto as a CGT asset, not currency
  • Collectables — subject to certain limitations and thresholds
  • Certain small business assets — which may also qualify for additional small business CGT concessions

Notably, your primary residence (main home) is generally exempt from CGT altogether under the main residence exemption, making the discount most relevant for investment assets held outside your home.

What is the CGT 50% discount in Australia?

The ATO requires a specific order of operations when calculating your capital gain. Getting this wrong can lead to underpaying or overpaying tax. Here is the correct sequence:

Step 1: Calculate your total capital gain — this is the sale proceeds minus your cost base (which includes the purchase price, brokerage, and certain other acquisition costs).

Step 2: Apply any capital losses — use current-year capital losses first, then any carried-forward losses from prior years. Critically, capital losses must be applied before the CGT discount, not after.

Step 3: Apply the 50% CGT discount to the remaining net gain.

Step 4: Include the discounted amount in your taxable income and report it in your annual income tax return.

Worked example:

  • Sale of shares: $150,000
  • Cost base: $50,000
  • Gross capital gain: $100,000
  • Less capital losses (carried forward): $10,000
  • Net capital gain before discount: $90,000
  • Less 50% CGT discount: $45,000
  • Taxable capital gain: $45,000

If your marginal tax rate is 37%, you would pay approximately $16,650 in tax on this gain — compared to $33,300 if the discount did not apply. That is a $16,650 saving from holding one day longer than 12 months.

Strategic CGT decisions for ASX investors

When does the CGT discount change in 2027?

Savvy investors use the CGT 50% discount not just passively, but as an active part of their portfolio management strategy. Here are some of the most effective approaches:

Timing disposals carefully
If you are approaching the 12-month mark on an asset, it almost always makes sense to wait until you cross the threshold before selling. The tax saving from the discount typically far outweighs any short-term market movements.

Harvesting capital losses
If you hold assets sitting at a loss, consider realising those losses in the same financial year as a large gain. Because losses are applied before the discount, they are effectively worth double in after-tax terms compared to offsetting post-discount gains.

Income splitting through trusts
Family trusts can distribute capital gains (after applying the 50% discount) to beneficiaries on lower marginal tax rates, further reducing the household’s overall tax burden. This requires proper legal and tax advice to implement correctly.

Superannuation timing
If you are approaching retirement and plan to move assets into a self-managed super fund, timing when you hold or sell assets can significantly affect your tax outcome. Inside super, the discount is 33.33% rather than 50%, so holding assets personally until they qualify for the full discount may be preferable in some circumstances.

Affordable housing bonus
If you own a residential rental property and provide affordable housing to low-to-moderate income earners through an approved rental housing provider, you may qualify for an additional 10% CGT discount — bringing your total concession to 60%. This is a niche but meaningful incentive for investors open to this type of tenancy arrangement. The eligibility criteria are specific, so confirm your arrangements qualify with a tax adviser before relying on this enhanced rate.

How to calculate CGT discount on shares?

If you are disposing of business assets, the CGT framework becomes considerably more complex — but also potentially more generous. The ATO provides a suite of small business CGT concessions that are applied in a specific sequence before the standard 50% discount is calculated. Misapplying the order can cost you significantly.

The four concessions, applied in this sequence, are:

  1. Small business 15-year exemption — if you have continuously owned an active business asset for 15 or more years and are aged 55 or older (or retiring or permanently incapacitated), the entire gain may be exempt from CGT. No further concessions need to be considered if this applies.
  2. Small business 50% active asset reduction — reduces the capital gain on qualifying active business assets by 50%. This step applies after the 15-year exemption test has been considered and found inapplicable or only partially applicable.
  3. Small business retirement exemption — allows up to $500,000 of capital gains to be contributed to superannuation tax-free over a lifetime. Amounts contributed under this exemption count toward the lifetime limit regardless of age, though investors under 55 must make the contribution to super.
  4. Small business rollover — defers the remaining gain if you reinvest in qualifying replacement assets within the prescribed timeframe.

Importantly, after applying whichever of the above concessions you are eligible for, you may still be able to apply the standard 50% CGT discount on any remaining gain — provided you meet the 12-month holding period and other eligibility criteria. This combination can result in a capital gain being reduced by as much as 75% before it reaches your assessable income.

One critical warning: the ATO’s anti-avoidance provisions under Part IVA of the Income Tax Assessment Act apply with particular force in this space. Arrangements that convert what were originally trading stock or ordinary income assets into capital assets — primarily to access the small business concessions or the 50% discount — can be unwound where the dominant purpose is tax reduction rather than genuine business or investment activity. The ATO is vigilant about these arrangements. Small business CGT concessions are complex and carry strict eligibility tests; specialist tax advice is strongly recommended before any disposal where these concessions may apply.

Property Investors: Negative Gearing, Main Residence, and Cost Base

The CGT 50% discount is frequently discussed in the context of Australian investment property, and for good reason — property transactions often involve the largest capital gains individual investors will ever realise. Several property-specific rules interact with the discount in ways that are worth understanding clearly.

Negative gearing and the CGT discount
Rental losses from negative gearing offset your ordinary income during the holding period, reducing your tax in those years. However, when you sell, those same revenue-account losses do not reduce your capital gain — the sale proceeds and cost base calculation operate entirely separately from the annual rental deficit. This means investors in negatively geared properties effectively receive two distinct tax benefits: annual deductions during the holding period, and then the 50% CGT discount on the eventual sale. The two concessions are complementary, not mutually exclusive.

Main residence exemption and partial CGT liability
Your primary home is generally fully exempt from CGT, representing the most valuable CGT concession available to individual taxpayers. However, if you have ever rented out your main residence or used it for income-producing purposes — even partially — a proportionate CGT liability may apply when you sell. The taxable portion is calculated based on the floor area used for income-producing purposes and the time during which the property was used that way. The 50% discount is then available on the taxable portion, provided the 12-month holding period is satisfied.

Cost base uplift through capital improvements
Capital improvements — such as renovations, extensions, new fencing, landscaping, or structural additions — are added to your cost base and directly reduce your capital gain on sale. This is a legally straightforward but frequently overlooked method of legitimately reducing your CGT exposure. Keeping meticulous records of all capital expenditure throughout ownership is not just good practice; it is a legal requirement, and underestimating your cost base because of poor records is one of the most common — and avoidable — sources of inflated CGT liabilities.

Residency Edge Cases: Temporary Residents, Dual Residency, and Apportionment

Residency status at the time of a CGT event is not always straightforward, and the consequences of getting it wrong are material. Several scenarios deserve specific attention.

Temporary residents
Individuals who hold temporary visas and are considered temporary residents for tax purposes are generally not entitled to the CGT 50% discount on most assets. The exception is taxable Australian property (such as Australian real estate or interests in land-rich entities), where the discount may still apply. If you hold shares, ETFs, or other non-property assets as a temporary resident, you should not assume the discount is available — confirm your entitlement with a registered tax agent.

Dual residency and time overseas
If you have spent extended periods overseas, you may have been a tax resident of both Australia and another country simultaneously under each country’s domestic rules. Australia’s tax treaties with various countries include tie-breaker rules that determine which country has primary taxing rights over your income and gains during periods of dual residency. For CGT purposes, your residency status at the date of the disposal (the CGT event date) is what determines discount eligibility — not your historical residency, and not your intention to return.

Apportionment for partial residency periods
Former Australian residents who became non-residents during the holding period of an asset may still access a partial CGT discount. The discount is apportioned based on the proportion of the total holding period during which the taxpayer was an Australian resident. This calculation can be complex, particularly for assets held across multiple periods of residency and non-residency, and professional advice is essential before any disposal in these circumstances.

Can you claim CGT discount on cryptocurrency?

In what represents the most significant change to Australian CGT in over 25 years, the Federal Government has announced that the 50% CGT discount will be abolished from 1 July 2027. This is not a minor adjustment — it fundamentally changes the tax treatment of long-term investment gains.

What replaces it?
From 1 July 2027, the discount method will be replaced with:

  • CPI indexation of the cost base — your purchase price is adjusted upward by the Consumer Price Index (CPI) for the holding period, meaning only real gains above inflation are taxed.
  • A 30% minimum tax rate on gains above the inflation-adjusted cost base.

How will existing assets be treated?
The reform will not apply retrospectively. For assets held before 30 June 2027, a hybrid system applies:

  • Gains accrued up to 30 June 2027 (from original cost to the asset’s value on that date) — the 50% CGT discount applies
  • Gains accrued after 1 July 2027 (from the 30 June 2027 value to eventual sale) — CPI indexation plus the 30% minimum tax applies

This split treatment applies to individuals, trusts, and partnerships. Practically speaking, the ATO will require investors to establish the market value of their assets as at 30 June 2027 — making accurate valuations at that date critically important.

What this means for your strategy now
The years between now and 30 June 2027 represent a window of opportunity. Investors using platforms like Crowdfolio to manage diversified portfolios should be actively reviewing their holdings, identifying assets with large unrealised gains, and working with a tax adviser to model whether realising gains before the cut-off date is beneficial given their personal circumstances. In many cases, locking in the 50% discount before the deadline will prove significantly more tax-efficient than deferring the sale into the new regime.

Special Circumstances and Edge Cases

Several special rules apply to the CGT discount that can catch investors off guard:

Relationship breakdown: If you received an asset through a property settlement following a relationship breakdown, the 12-month holding period includes the time the asset was held by your former spouse. So if they held it for eight months and you held it for a further six months, the combined 14-month period satisfies the eligibility requirement.

Deceased estates: Assets inherited from a deceased estate where the deceased acquired the asset on or after 20 September 1985 can still qualify for the CGT discount. The holding period generally commences from the date the deceased originally acquired the asset.

Cryptocurrency: The ATO treats cryptocurrency as a CGT asset. If you hold crypto for more than 12 months before disposing of it (including selling, swapping, or using it to purchase goods), you are entitled to the 50% discount on any gain — though meticulous record-keeping of acquisition dates and cost bases is essential.

New builds: Under the transitional arrangements for the 2027 reforms, investors in newly constructed residential properties retain certain preferential treatment. The precise rules for new builds are still being legislated, and investors should monitor ATO guidance closely.

Key Takeaways

  • The CGT 50% discount reduces your taxable capital gain by half when you hold an eligible asset for at least 367 days (12 months, excluding the acquisition and disposal dates) and are an Australian tax resident.
  • Capital losses must be applied to your gain before the 50% discount is applied — getting this order wrong can result in an incorrect tax calculation.
  • The discount applies to a wide range of assets including ASX shares, ETFs, investment property, international shares, and cryptocurrency — but not to companies.
  • Self-managed super funds (SMSFs) access a reduced 33.33% CGT discount, not the full 50% available to individual investors.
  • Small business CGT concessions can be stacked with the general 50% discount in a specific four-step sequence, potentially reducing a gain by up to 75% — but Part IVA anti-avoidance provisions apply strictly to arrangements designed primarily to access these concessions.
  • Property investors benefit from two complementary concessions: annual negative gearing deductions during ownership and the 50% CGT discount on eventual sale — and capital improvements throughout ownership reduce the taxable gain.
  • Temporary residents are generally not entitled to the discount on non-property assets; dual residents and former residents should have their eligibility assessed at the date of disposal, with apportionment applying where residency changed during the holding period.
  • From 1 July 2027, the 50% CGT discount will be replaced by CPI indexation of the cost base plus a 30% minimum tax — one of the largest changes to Australian investment taxation in decades.
  • Gains accrued up to 30 June 2027 on existing assets will still attract the 50% discount under a hybrid transitional arrangement, making asset valuations as at that date critically important.
  • The period between now and 30 June 2027 is a strategic window for Australian investors to review their portfolios and potentially crystallise gains under the current, more favourable discount regime.
  • Investors providing qualifying affordable housing may access an additional 10% CGT discount, bringing the total concession to 60%.
