Every July, thousands of Australians open their ETF tax statement and discover a nasty surprise: the tax office says they earned more than the cash they actually received. Some find capital gains on a return where they sold nothing at all.
Here’s the short answer: an ETF is a trust, not a company. The fund pays no tax itself — every dollar of income and every capital gain it realises flows through to you, whether or not you saw any cash. In 2026-27, your annual AMMA statement (AMIT Member Annual statement) tells you what to declare, and it rarely matches your bank account. Master its three numbers — attributed income, cash received, and the AMIT cost base adjustment — and tax time becomes boring. Ignore them and you’ll overpay or file wrong.
This guide covers ETF distributions in 2026-27, reading your AMMA statement, the cost base adjustments investors forget, five worked examples, and what the 1 July 2027 CGT overhaul means for ETF holders. Comparing structures? See our CGT on shares guide.
Why your ETF tax never matches your bank statement
When you buy shares in BHP, BHP pays company tax, then hands you a dividend. Simple. When you buy units in an ETF, there is no company and no company tax. The ETF is a managed investment trust: a pool of assets held for unitholders, and the trust itself is invisible to the tax system.
Most big ASX ETFs — Vanguard, Betashares, iShares, VanEck — have elected into the AMIT regime (Attribution Managed Investment Trust). Under AMIT, the fund “attributes” its taxable income to you for the financial year it was earned. Attribution is not the same as payment. The fund can attribute $1,650 of income to you while paying only $1,300 in cash, and the ATO taxes you on the $1,650. Betashares’ 2026 tax guide is blunt: cash distributions “should not be used as assessable income for the preparation of your tax return.”
The gap between attributed and received isn’t lost. It adjusts your units’ cost base — up when attributed income exceeds cash, down when cash exceeds attributed income — so the same dollars aren’t taxed twice. That adjustment is the most misunderstood line in Australian investing. (Full mechanics: our CGT cost base guide.)
Your AMMA statement, decoded
Your AMMA statement arrives around late July. Part B lists your attributed components — each taxed differently:
| Component | How it’s taxed | What to watch |
|---|---|---|
| Franked income | Declare the grossed-up amount (cash + franking credit); claim the credit as an offset | You get the credit even though the company, not you, paid the tax |
| Unfranked income | Added to taxable income at your marginal rate | No offset — full rate |
| Discounted capital gains | Declare at the CGT discount method — the fund already applied the 50% discount | Do NOT halve it again |
| Non-discounted capital gains | Fully assessable at your marginal rate | From assets the fund held under 12 months |
| Foreign income | Assessable; foreign income tax offset may apply | You must calculate the offset — don’t just copy “foreign tax paid” |
| Tax-deferred amounts | Not assessable now — but they reduce your cost base | The tax is postponed, not forgiven |
| AMIT cost base net amount | Not income at all — it adjusts your cost base up or down | Skipping this is how double taxation happens |
Much of what trips people up is the cost base, not this year’s return.
Worked example 1: taxed on money you never received
Meet Maya. In March 2025 she bought 500 units of an Australian shares ETF at $20 each — a $10,000 cost base. In FY2025-26 she received $1,300 in cash distributions across the year. Then her AMMA statement arrives:
- Attributed income: $1,650
- Cash distributions received: $1,300
- AMIT cost base net amount: $350 shortfall (increase)
Maya declares $1,650 as income — not $1,300 — and increases her cost base to $10,350. Two years later she sells all her units for $12,000. Her capital gain is $12,000 − $10,350 = $1,650, not $2,000. That $350 was already taxed as distribution income in FY2025-26; without the cost base increase, she’d pay tax on it a second time. At a 32% marginal rate (30% + 2% Medicare levy), the adjustment saves her $112.
The ATO rule behind it: your cost base rises by assessable income attributed to you and falls by actual payments received, netted each year into the AMIT cost base net amount. Attributed income above cash = shortfall (increase); cash above attributed income = excess (decrease).
Worked example 2: tax-deferred — the bill that follows you
Now suppose Maya’s AMMA also shows $420 of tax-deferred income — common in property ETFs, where building allowances shelter income from tax. It’s not assessable this year, so she declares nothing — but her cost base falls $420, from $10,350 to $9,930.
Selling at $12,000, her gain is now $2,070 instead of $1,650. The tax wasn’t forgiven — it was postponed until sale, where it’ll likely qualify for the 50% CGT discount instead of ordinary income rates. A good trade, but only if you tracked the adjustment.
One edge case: if downward adjustments would push your cost base below zero, the excess becomes a capital gain in that year — you can’t defer tax below a zero cost base.
Worked example 3: the phantom capital gain
Maya sold nothing in FY2025-26. Yet her AMMA shows a $900 discounted capital gain. What happened? In March, the ETF rebalanced — it sold a bank holding it had owned for three years and replaced it with another. The fund’s gain flows straight through to unitholders.
Because the fund held the asset for more than 12 months, it already applied the 50% CGT discount before attributing the $900 to Maya. She declares $900 under the CGT discount method — and must not halve it to $450. The $900 is already the discounted figure. At her 32% rate, that’s $288 of tax on a gain she never saw as a separate payment.
This is why “I didn’t sell anything” is never a reason to skip the AMMA statement. In a year your portfolio looks flat, your fund’s internal trading can still generate real, taxable gains.
Worked example 4: the July trap — which year is it?
Maya’s June-quarter distribution of $410 was paid on 20 July 2026. Her bank statement says July; her brain says FY2026-27. Both wrong. Under AMIT, the distribution belongs to the year it was attributed to — the year ended 30 June 2026. Her AMMA statement confirms it. Report it in the wrong year and you’ve misreported two years at once. This is one of the most common ETF filing errors: the AMMA statement, not your bank statement, decides the year.
Franking credits and foreign income: the two lines people mangle
Franking. When your ETF holds Australian companies, their franking credits flow through to you. Say Maya’s AMMA shows $1,400 of franked income with $600 of franking credits. She declares $2,000 (the grossed-up amount) as income, then claims the $600 as a tax offset — a dollar-for-dollar reduction in her tax bill. If her credits exceed her total tax payable, the ATO refunds the difference, which is why franking is gold for retirees and low-income earners. The 45-day holding rule is managed at the fund level, so you take the credits as shown.
Foreign income. International ETFs pass through foreign dividends and the foreign tax already withheld on them. The trap: you can’t just copy the “foreign tax paid” figure from Part C of the AMMA into the foreign income tax offset field. The offset must be calculated under the Division 770 rules, and the number is often different. Get it wrong and you either leave money on the table or claim an offset you’re not entitled to. Our income tax calculator can model the overall effect, but the FITO calculation itself deserves care — or an accountant.
DRP: reinvesting doesn’t make the tax vanish
A distribution reinvestment plan feels like you never received anything — the cash never touches your account; it just buys more units. For tax, though, a DRP distribution is identical to cash: the full attributed amount is assessable income in that year.
And each reinvestment creates a new parcel with its own acquisition date and cost base (the price on reinvestment day). Five years of quarterly DRP reinvestments means twenty parcels, each with a different 12-month discount clock. When you later sell part of your holding, which parcels you dispose of determines your gain. Keep a register: date, units, price per reinvestment. Your future self will thank you.
What the 1 July 2027 CGT overhaul means for ETF holders
Big change on the horizon, and ETF investors are directly in its path. The Treasury Laws Amendment (Tax Reform No. 1) Act 2026 received Royal Assent on 26 June 2026. From 1 July 2027, the 50% CGT discount is replaced for individuals, trusts and partnerships by cost base indexation — your cost base is adjusted for inflation and you’re taxed on the real gain — plus a 30% minimum tax rate on those real gains. What this means for your ETFs:
- Gains accrued before 1 July 2027 keep the old treatment. Discounted capital gains your fund distributes for periods up to 30 June 2027 still carry the 50% discount. Don’t panic-sell on rumour; the transition is pro-rated.
- Distributions after 1 July 2027 use the new method inside the fund. The “discounted capital gain” line on your AMMA changes character — indexation replaces the halving, and the 30% minimum rate applies to the real gain even if your marginal rate is lower.
- Your cost base records become more important, not less. Under indexation, the timing of every dollar added to or subtracted from your cost base — including those AMIT adjustments — directly changes the inflation calculation. Sloppy records now mean wrong tax later.
- Super and the family home are untouched. Capital gains inside super are taxed as before — including the one-third discount for complying funds — gains in pension phase remain tax-free, and the main residence exemption is unchanged.
The ATO is still publishing guidance on the transition mechanics, so treat any specific strategy as provisional. But one thing is certain: the investors who sail through 2027-28 will be the ones whose cost base registers are already immaculate. (Our 50% discount guide covers the current rules while they last.)
5 mistakes that cost ETF investors real money
1. Declaring the cash, not the attributed amount. Your bank statement is not your tax return. The AMMA’s attributed figure is what the ATO pre-fills and matches against.
2. Halving a discounted capital gain a second time. The fund already applied the 50% discount. Enter the figure as shown under the CGT discount method — ATO data-matching catches this mismatch.
3. Putting a July-paid distribution in the wrong year. Paid in July for the June quarter = prior financial year. Thousands of investors get this backwards every year.
4. Ignoring AMIT cost base adjustments. Skip the annual adjustment and you’ll pay tax twice on the same dollars when you sell — or miscalculate your gain by thousands on a large holding.
5. Copying “foreign tax paid” straight into the FITO field. The foreign income tax offset has its own calculation. The AMMA figure is an input, not the answer.
Tips for a painless ETF tax time
- Wait for every AMMA statement before lodging. They typically land in late July. Lodge in early July on prefill alone and you’ll almost certainly need an amendment.
- Keep a cost base register per ETF. One row per year: opening cost base, AMIT adjustment, tax-deferred amounts, DRP parcels, closing cost base. A spreadsheet is fine.
- Save every AMMA as a PDF the day it arrives. Registries redesign portals; old statements vanish. The ATO expects records for five years after you report the gain or loss.
- Don’t trust prefill blindly. Cross-check it against your AMMA statements — especially the cost base adjustment lines, which don’t appear in prefill at all.
- Model a sale before you sell. Run the numbers through our CGT calculator — with the 1 July 2027 transition approaching, timing a large disposal a few months either way can change the outcome materially.
FAQ
Do I pay tax on ETF distributions if I reinvest them through a DRP?
Yes. Reinvested distributions are fully assessable in the year they’re attributed, exactly like cash. The reinvestment just buys new units — each a separate parcel with its own cost base and acquisition date for future CGT.
I didn’t sell any units — why does my return show a capital gain?
Your fund sold assets internally — rebalancing, redemptions, corporate actions — and realised gains that are attributed to you whether or not you sold. Check the capital gains lines on your AMMA statement.
Why doesn’t the income on my tax return match the cash I received?
Because you’re taxed on attributed income, not cash received. The two differ whenever the fund retains amounts, passes through tax-deferred income, or attributes gains without matching cash. The AMIT cost base net amount on your AMMA bridges the gap by adjusting your cost base so nothing is taxed twice.
I bought units in June and the distribution arrived in July — which year’s return?
The year the income was attributed to, which your AMMA statement confirms — normally the financial year ended 30 June. A distribution paid in July for the June quarter belongs to the prior financial year, even though the cash arrived after 1 July.
Do I still get the 50% CGT discount on gains my ETF distributes?
For distributions attributed for periods up to 30 June 2027, yes — the fund applies the discount before attributing the gain to you, and you declare it under the CGT discount method without halving it again. From 1 July 2027 the discount is replaced by indexation plus a 30% minimum tax under the new CGT rules.
Should I wait for my AMMA statement before lodging my tax return?
Yes. AMMA statements are usually issued in late July and contain attributed components, cost base adjustments and foreign tax details that don’t appear in ATO prefill. Lodging early on prefill alone is the fastest route to an amendment.
The bottom line
ETF tax has exactly three moving parts: what you’re attributed, what you received, and what happens to your cost base as a result. Get those three right — declare the attributed amount, lodge it in the right year, and adjust your cost base every June — and the rest is transcription from your AMMA statement. The investors who get burned treat an ETF like a term deposit: cash in, cash out, nothing in between. A trust is never that simple, but it rewards the small effort of understanding it. Keep the register, wait for the statement, and check the numbers before you sell.
