Capital Gains Tax Discount Australia 2025: Complete Guide to the 50% CGT Discount

What is the 50% CGT Discount?

The 50% Capital Gains Tax (CGT) discount is a significant tax concession that allows eligible Australian taxpayers to reduce their capital gain by half before it is added to their taxable income. This discount was introduced on 21 September 1999 to encourage long-term investment and replace the previous indexation method.

When you sell an asset (such as shares, property, or cryptocurrency) for more than you paid for it, the profit is called a capital gain. Without the discount, this entire gain would be added to your taxable income and taxed at your marginal tax rate. With the 50% discount, only half the gain is taxable.

Key Benefit

The 50% CGT discount can effectively halve the tax you pay on investment profits. For someone in the 37% tax bracket, this means paying an effective tax rate of just 18.5% on their capital gains instead of 37%.

How the CGT Discount Works

The calculation process is straightforward:

Calculate your capital gain: Sale price minus cost base (purchase price plus associated costs)
Apply any capital losses: Reduce the gain by any available capital losses
Apply the 50% discount: If eligible, reduce the remaining gain by 50%
Add to taxable income: The discounted amount is added to your other income and taxed at your marginal rate

Who is Eligible for the CGT Discount?

Not everyone can claim the 50% CGT discount. The ATO has specific eligibility requirements that must be met.

Entity Type	CGT Discount Rate	Eligibility
Individuals	50%	Eligible (if held 12+ months)
Trusts (distributing to individuals)	50%	Eligible (if held 12+ months)
Superannuation Funds	33.3%	Eligible (if held 12+ months)
Companies (Pty Ltd)	0%	NOT eligible - no discount
Non-residents (after 8 May 2012)	0%	NOT eligible for Australian property

Important: Companies Cannot Claim the Discount

Companies (Pty Ltd entities) are NOT eligible for the CGT discount. Capital gains in a company are taxed at the full company tax rate (25% or 30%). This is a crucial consideration when choosing your investment structure.

Non-Resident Rules

Foreign residents face restricted access to the CGT discount:

Assets acquired before 8 May 2012: May still be eligible for discount on gains accrued until that date
Assets acquired after 8 May 2012: No CGT discount available for taxable Australian property (primarily real estate)
Foreign residents remain eligible for the discount on non-Australian assets

The 12-Month Holding Period Rule

The 12-month rule is the cornerstone of the CGT discount. You must own the asset for more than 12 months before selling to qualify for the discount.

Critical: "More Than" 12 Months

The rule requires more than 12 months - not 12 months exactly. If you bought shares on 15 January 2024, you must sell on 16 January 2025 or later to qualify. Selling on exactly 15 January 2025 would NOT qualify.

How the 12-Month Period is Calculated

Start date: The day after you acquire the asset (contract date, not settlement date)
End date: The date you dispose of the asset (contract date for property, trade date for shares)
Counting: The period must exceed 365 days (366 in a leap year)

Example: Timing the 12-Month Rule

Scenario: You bought BHP shares on 20 March 2024

Ownership period starts: 21 March 2024

12 months completed: 20 March 2025

First eligible sale date: 21 March 2025

Selling on 20 March 2025 = No discount (exactly 12 months)

Selling on 21 March 2025 = 50% discount applies

Step-by-Step Calculation Examples

Example 1: Share Investment

Sarah buys 1,000 shares in Commonwealth Bank at $100 each (plus $20 brokerage) and sells them after 18 months at $130 each (minus $20 brokerage).

Step	Calculation	Amount
1. Purchase cost (cost base)	1,000 x $100 + $20 brokerage	$100,020
2. Sale proceeds	1,000 x $130 - $20 brokerage	$129,980
3. Capital gain (before discount)	$129,980 - $100,020	$29,960
4. Apply 50% CGT discount	$29,960 x 50%	$14,980
5. Taxable capital gain	Added to income	$14,980

If Sarah is in the 32.5% tax bracket, her CGT liability would be:

Without discount: $29,960 x 32.5% = $9,737 tax
With 50% discount: $14,980 x 32.5% = $4,869 tax
Tax saved: $4,868

Example 2: Investment Property

Michael bought an investment property in Brisbane for $500,000 in 2020 and sells it in 2025 for $750,000.

Component	Amount
Purchase price	$500,000
+ Stamp duty	$15,925
+ Legal fees (purchase)	$1,500
+ Capital improvements (new deck)	$25,000
Total cost base	$542,425
Sale price	$750,000
- Agent commission (2%)	-$15,000
- Legal fees (sale)	-$1,200
Net sale proceeds	$733,800
Capital gain (before discount)	$191,375
After 50% discount	$95,688

At the 37% marginal tax rate, Michael's tax would be:

Without discount: $191,375 x 37% = $70,809
With discount: $95,688 x 37% = $35,405
Tax saved: $35,404

CGT Discount for Property Investors

Property investors benefit significantly from the CGT discount, especially given the typically large capital gains involved in real estate transactions.

What's Included in the Cost Base for Property?

Purchase price: The contract price of the property
Stamp duty: State government transfer duty
Legal and conveyancing fees: Both purchase and sale
Capital improvements: Renovations, additions, structural changes
Real estate agent commissions: On sale
Marketing costs: Advertising for sale

Important: Deductible Expenses Are NOT Part of Cost Base

Expenses you have already claimed as tax deductions (such as repairs, property management fees, insurance, or depreciation) cannot also be added to your cost base. This includes depreciation claimed on the building and fixtures.

Capital Works Deductions and CGT

If you've claimed capital works deductions (Division 43 - building depreciation at 2.5% per year), your cost base is reduced by the amount deducted. This means a larger capital gain when you sell.

Example: Capital Works Impact

Purchase price: $400,000 (building value $250,000)

Years owned: 8 years

Capital works claimed: $250,000 x 2.5% x 8 = $50,000

Adjusted cost base: $400,000 - $50,000 = $350,000

This increases your capital gain by $50,000

The CGT discount is particularly valuable for share investors due to the frequency of trading and potential for significant gains over time.

Key Considerations for Share Investors

Parcel Selection

When you sell only part of your shareholding, you can choose which parcels to sell. This allows tax planning:

Sell high cost base parcels first: Minimises the capital gain
Sell parcels held 12+ months: Ensures CGT discount applies
Sell parcels with losses: Create losses to offset other gains

Dividend Reinvestment Plans (DRP)

Each DRP purchase creates a new parcel with its own acquisition date and cost base. This can complicate CGT calculations but also provides flexibility.

DRP Tip

DRP shares are considered acquired on the date dividends are paid, not when originally enrolled. Each DRP allocation has its own 12-month clock for the CGT discount.

ETF Distributions

ETF investors receive annual tax statements showing various components including "CGT concession" amounts. This reflects capital gains within the ETF that already qualify for the discount. You may need to make adjustments to your cost base based on these distributions.

CGT Discount and Cryptocurrency

The ATO treats cryptocurrency as a CGT asset, and the 50% discount applies if you hold crypto for more than 12 months before disposing of it.

CGT Events for Crypto

The following actions trigger CGT events:

Selling crypto for Australian dollars
Trading one cryptocurrency for another (e.g., BTC to ETH)
Using crypto to purchase goods or services
Gifting cryptocurrency
Converting crypto to stablecoins

Crypto Trading Warning

Each crypto-to-crypto trade is a CGT event. If you regularly swap between cryptocurrencies, you may lose the 12-month discount on holdings that are frequently traded. The clock resets each time you acquire new crypto.

Personal Use Asset Exemption

Cryptocurrency acquired for less than $10,000 and used personally (e.g., buying goods) may qualify for the personal use asset exemption. However, this rarely applies as most crypto is held as an investment.

CGT Discount in Super Funds (33.3%)

Superannuation funds receive a reduced CGT discount of 33.3% (one-third) instead of 50%. This applies to both self-managed super funds (SMSFs) and industry/retail funds.

Scenario	Individual	Super Fund
Capital gain	$100,000	$100,000
CGT discount	50%	33.3%
Taxable gain	$50,000	$66,700
Tax rate	37%*	15%
Tax payable	$18,500	$10,005

*Assuming 37% marginal rate for individual

Despite the lower discount, super funds often pay less total CGT because of the low 15% tax rate.

Pension Phase

Assets held in pension phase (retirement phase) within a super fund are exempt from CGT entirely - the 0% tax rate applies to both income and capital gains. This makes transferring assets to pension phase before selling highly advantageous.

Timing Strategies to Maximise the Discount

Strategy 1: Wait for the 12-Month Mark

If you're close to the 12-month holding period, waiting a few extra days can save significant tax. Model the impact before making a decision.

Example: Worth the Wait?

Capital gain: $50,000

Marginal tax rate: 37%

Sell before 12 months: $50,000 x 37% = $18,500 tax

Sell after 12 months: $25,000 x 37% = $9,250 tax

Waiting saves: $9,250

Strategy 2: Time Sales Around Financial Years

Consider which financial year your sale falls into:

Low income year: If you expect lower income next year (career break, study), delay the sale
High income year: If income will be higher next year, sell this year
June 30 deadline: The contract date determines the financial year, not settlement

Strategy 3: Harvest Capital Losses

Before June 30, review your portfolio for loss-making positions. Selling these can offset gains and reduce your CGT liability. You can reinvest in similar (but not identical) assets after selling.

Strategy 4: Spread Gains Across Years

For large portfolios, consider selling in stages across multiple financial years to avoid pushing yourself into higher tax brackets.

CGT Event Timing and Settlement Dates

Understanding when a CGT event occurs is crucial for both the 12-month rule and determining which financial year the gain falls into.

Asset Type	CGT Event Date
Shares (on-market)	Trade date (T+2 settlement doesn't matter)
Property	Contract date (not settlement date)
Cryptocurrency	Date of transaction/disposal
Off-market share sales	Date contract becomes binding

Property Example

If you sign a contract to sell your investment property on 25 June 2025 with settlement on 20 July 2025, the capital gain is assessable in the 2024-25 financial year (contract date), not 2025-26.

Capital Losses and the CGT Discount

Capital losses interact with the CGT discount in a specific order that's important to understand.

Order of Application

Calculate total capital gains for the year
Apply capital losses (current year and carried forward) against total gains
Apply the 50% CGT discount to the remaining gain (if eligible)

Key Point: Losses Applied Before Discount

Capital losses reduce your gain BEFORE the 50% discount is applied. This means losses effectively offset gains at full value, not at 50%.

Example: Losses and Discount

Capital gain (held 2 years): $80,000

Capital loss from other sale: $20,000

Step 1: $80,000 - $20,000 = $60,000 (net gain)

Step 2: $60,000 x 50% = $30,000 (after discount)

Taxable capital gain: $30,000

Capital Losses Cannot Create a Refund

If your capital losses exceed your capital gains, you cannot use the excess to reduce your other income. Instead, carry the loss forward to offset future capital gains indefinitely.

Main Residence Exemption Interaction

Your main residence (home) is generally exempt from CGT. However, the interaction between the main residence exemption and CGT discount becomes relevant when:

You rent out part of your home
You use part of your home for business
You move out and rent your home (using the 6-year rule)
The property was previously an investment property

Partial Main Residence Exemption

When only part of the gain is exempt (e.g., you rented out 30% of the property), the taxable portion can still qualify for the 50% CGT discount if held for more than 12 months.

Example: Partial Exemption

Total capital gain: $200,000

Main residence exemption: 70%

Taxable portion: 30% x $200,000 = $60,000

After 50% CGT discount: $60,000 x 50% = $30,000

Final taxable gain: $30,000

The 6-Year Absence Rule

If you move out of your main residence and rent it out, you can maintain the main residence exemption for up to 6 years. During this period, you cannot claim another property as your main residence.

Frequently Asked Questions

Can I get the CGT discount if I'm a temporary resident?

Temporary residents can claim the CGT discount on assets that aren't "taxable Australian property" (mainly real estate). However, temporary residents are generally only taxed on Australian-sourced income, so the discount is most relevant for Australian property sales.

Does the 12-month period include weekends and public holidays?

Yes, the 12-month period is calendar days. All days count, including weekends and public holidays. The period must exceed 365 days (or 366 in a leap year).

What if I bought shares in multiple parcels?

Each parcel has its own 12-month clock. When selling, you can choose which parcels to sell (specific identification method) or use FIFO (first in, first out). This allows you to strategically select parcels that qualify for the discount.

Is there a CGT discount for inherited assets?

Yes. For inherited assets, you can include the deceased's ownership period when calculating whether the 12-month rule is satisfied. The cost base rules vary depending on when the deceased acquired the asset.

Can a trust distribute capital gains with the discount?

Yes. When a trust distributes capital gains to individual beneficiaries, those beneficiaries can receive the benefit of the 50% discount (if the asset was held by the trust for 12+ months). The trustee must correctly categorise the distribution.

What about shares received through employee share schemes?

The 12-month period generally starts when you acquire the shares under the scheme (or when taxing point occurs for deferred schemes). The rules are complex - seek specific advice for employee share schemes.
