Tax on Investments Australia: What You Need to Know (2026)
Every Australian investor eventually faces the same realisation: the ATO has a stake in your returns. Understanding how investment income is taxed before you invest — not after — can meaningfully change your after-tax returns and the decisions you make.
This guide covers how Australian investment income is taxed in 2026: dividends, capital gains, ETFs, managed funds, interest income, and franking credits. It's written to be genuinely useful for everyday investors, not just accountants.
Disclaimer: This guide provides general information only and does not constitute tax or financial advice. Australian tax law is complex and individual circumstances vary significantly. Speak with a registered tax agent or accountant before making decisions based on tax considerations.
The Two Main Types of Investment Income
Investment income in Australia falls into two broad categories, each taxed differently:
- Income returns: Dividends from shares, distributions from ETFs and managed funds, and interest from savings accounts or bonds. Taxed as ordinary income in the year you receive them.
- Capital gains: Profit from selling an investment for more than you paid for it. Subject to Capital Gains Tax (CGT). Significant discounts apply if you hold the investment for more than 12 months.
Understanding both — and how to legally minimise them — is central to building wealth efficiently in Australia.
Dividend Tax: How Australian Share Income Is Taxed
When an Australian company pays you a dividend, it is taxed as ordinary income. The dividend is added to your other income (salary, business income, etc.) and taxed at your marginal tax rate.
2026 Australian income tax rates (residents):
| Taxable income | Marginal tax rate |
|---|---|
| $0 – $18,200 | 0% (tax free threshold) |
| $18,201 – $45,000 | 19% |
| $45,001 – $120,000 | 32.5% |
| $120,001 – $180,000 | 37% |
| $180,001+ | 45% |
The Medicare Levy (2%) applies in addition to income tax for most residents.
Example: You earn $80,000 from your job and receive $2,000 in dividends. The $2,000 is added to your $80,000, giving taxable income of $82,000. The $2,000 in dividends is effectively taxed at your marginal rate of 32.5% (plus Medicare Levy).
Franking Credits: One of the Best Features of Australian Investing
This is where Australian investing has a genuine advantage over international shares —
dividend imputation (franking credits).
When an Australian company pays tax on its profits at the corporate tax rate (currently 30% for large companies or 25% for small companies), and then pays dividends to shareholders, those dividends come with "franking credits" attached — representing the tax already paid.
As a shareholder, you can use these franking credits to offset your own income tax liability.
How it works in practice:
A company pays a fully franked dividend of $700 to a shareholder. The attached franking credit is $300 (representing the 30% corporate tax already paid on the $1,000 of profit behind the dividend).
The shareholder declares $1,000 of dividend income (the $700 cash + $300 grossed-up credit). Their tax on $1,000 at 32.5% = $325. They subtract the $300 franking credit. Net tax payable: $25.
If your marginal tax rate is lower than the corporate tax rate: You get a refund. An investor in the 19% tax bracket receives the difference back as a cash refund from the ATO. This is why Australian shares with franked dividends are particularly attractive for low-income investors and retirees — they often receive significant franking credit refunds.
Key ETFs that distribute franked dividends: VAS (Vanguard Australian Shares ETF) and A200 (BetaShares Australia 200) distribute franked dividends. International ETFs like VGS do not — dividends from overseas companies are unfranked.
Capital Gains Tax (CGT): Selling Your Investments
When you sell an investment for more than you paid for it, the profit is a
capital gain and is subject to Capital Gains Tax.
The 12-Month CGT Discount
This is one of the most important tax rules every Australian investor needs to know:
if you hold an investment for more than 12 months before selling, your capital gain is discounted by 50% before being added to your taxable income.
Example:
- You buy $10,000 of VAS
- You sell it 18 months later for $14,000
- Your capital gain is $4,000
- Because you held it for over 12 months, only $2,000 (50%) is included in your taxable income
- At a marginal rate of 32.5%, the tax on the gain is $650 — not $1,300
If you held for less than 12 months: The full $4,000 would be added to your income, with tax of $1,300 at the same rate.
The 12-month CGT discount is a powerful incentive to invest for the long term rather than trade frequently.
Capital Losses
Capital losses (selling for less than you paid) can offset capital gains in the same year. If your net position is a capital loss, you can carry it forward to offset future capital gains. Capital losses cannot be used to reduce ordinary income (salary, dividends) — only capital gains.
What Triggers CGT?
CGT events are triggered by:
- Selling shares or ETFs
- Transferring shares between accounts (in some cases)
- Certain corporate actions (mergers, demergers, bonus share issues can have CGT implications)
- Selling cryptocurrency
CGT is NOT triggered by:
- Receiving dividends (taxed as income, not a CGT event)
- Watching your shares increase in value (unrealised gains are not taxable)
- Reinvesting dividends through a DRP (though the reinvested amount becomes your new cost base)
ETF and Managed Fund Tax: Distributions Explained
ETFs and managed funds distribute income to unitholders, typically quarterly or annually. These distributions can include:
- Australian dividends (potentially franked)
- Foreign income from international shares held by the fund
- Capital gains realised by the fund when it sells holdings internally
- Interest income from bond holdings (in diversified funds)
Each component is taxed differently, and your annual tax statement from the fund will break these down. This is why many financial advisers recommend keeping investment records carefully — the tax components are relevant to your return.
VDHG Tax Complexity
VDHG (Vanguard Diversified High Growth ETF) distributes large end-of-year income distributions that can include significant capital gains components. For investors in high tax brackets, this can create an unexpectedly large tax bill in distribution years. This is a known consideration for investors with large VDHG positions in taxable accounts — not a reason to avoid it, but worth understanding.
Interest Income: Savings Accounts and Term Deposits
Interest earned on savings accounts, term deposits, and cash management accounts is taxed as ordinary income at your marginal rate. There are no special discounts or concessions.
Example: $50,000 in a savings account earning 5% = $2,500 interest. At a 32.5% marginal rate, you pay $812.50 in tax on this income.
Interest income is reported to the ATO directly by banks — it appears pre-filled on your tax return if you use myTax.
Negative Gearing: When Investment Losses Offset Income
If your investment expenses exceed your investment income in a given year, you may be "negatively geared." This net investment loss can be used to reduce your total taxable income.
In practice for share investors:
- Margin loan interest exceeding dividend income may be deductible
- Some platform fees and subscription costs (data, research tools) used for investing may be deductible
- Brokerage costs are typically added to the cost base of your investment rather than deducted in the year incurred
Negative gearing is more commonly associated with investment property, but it applies to shares and managed funds as well. Speak with a tax accountant to understand which of your investment expenses are deductible in your situation.
International Shares and Withholding Tax
When you receive dividends from US or other international shares, the foreign country typically withholds tax before paying you. For US shares, a 15% withholding tax applies for Australian residents (under the Australia-US tax treaty, provided you submit a W-8BEN form to your broker).
This withholding tax is usually creditable against your Australian tax liability — you don't pay full Australian tax plus the withheld amount. Your broker or ETF fund's annual tax statement will show foreign tax credits applicable to your situation.
Record Keeping: What You Need for Tax Time
The ATO requires you to keep records of all investment transactions. For each purchase and sale, record:
- Date of transaction
- Asset purchased or sold
- Number of units or shares
- Total consideration (cost or proceeds)
- Any transaction costs (brokerage)
- Dividends received and franking credits
Your investment platform will provide annual tax statements that contain most of this information. Keep these statements permanently — you may need them to calculate cost bases when you sell investments years or decades later.
If you use tax software (myTax, TaxAgent, or platforms like H&R Block online), many investment platforms integrate their tax data directly.
Tax-Effective Investment Strategies for Australians
1. Use the 50% CGT discount: Hold investments for 12+ months before selling to halve your capital gains tax.
2. Harvest capital losses: If you have underperforming investments in a given tax year, consider selling them to realise a capital loss that can offset other gains. (Be careful of "wash sale" rules — repurchasing similar assets immediately after selling to crystallise a loss may be challenged by the ATO.)
3. Use super for long-term investments: Investments inside super are taxed at 15% on income and 10% on capital gains for complying funds (effectively 7.5% after the discount). For high-income earners, this is substantially lower than outside super rates.
4. Time your sales: If you know you're approaching a lower-income year (parental leave, career break), consider realising capital gains in that year when your marginal rate is lower.
5. Invest in franked dividend stocks: Fully franked dividends effectively reduce your net tax rate on that income, particularly valuable for lower and middle-income investors.
The Verdict: Understanding Investment Tax Pays Off
Tax is not a reason to avoid investing — it's a reason to invest intelligently. Understanding franking credits, the CGT discount, and the tax treatment of different asset types allows you to structure your portfolio to legally minimise tax and keep more of your returns.
For investors with growing portfolios, working with a tax accountant familiar with investment income is genuinely worthwhile — the fee often pays for itself in tax savings.
Frequently Asked Questions
Do I need to declare investment income on my Australian tax return?
Yes — all dividends, ETF distributions, capital gains, and interest income must be declared on your annual tax return. Most banks and investment platforms provide pre-filled data through the ATO's systems.
Can I avoid CGT by not selling my investments?
Yes — unrealised capital gains (increases in value while you hold an investment) are not taxable. CGT is only triggered when you sell (or trigger another CGT event).
How do I claim franking credits on my tax return?
Franking credits are included in your investment platform's annual tax statement. When you lodge your tax return, include the grossed-up dividend amount and the franking credit amount — myTax applies them automatically.
Is there tax on ETF distributions?
Yes — ETF distributions include income components (dividends, foreign income) taxed as ordinary income, and potentially capital gains distributions. Your annual tax statement from the fund breaks these down.
Do I need to lodge a tax return if I only have investment income?
If your total income (including investment income) exceeds the tax-free threshold of $18,200, you must lodge a tax return. Even below this threshold, you may want to lodge to claim franking credit refunds.
