You Are Taxed on the Fund's Trading, Not on Yours
A managed fund is a flow-through structure: it does not pay tax itself, it attributes its income and realised capital gains to unit holders each year. That means you can owe tax on a fund you did not sell, in a year the unit price fell, because the manager sold something inside it.
- The answer: Annual distributions carry interest, dividends, franking credits and realised capital gains, each taxed in your hands under its own rules.
- The trap: Reinvested distributions are taxed exactly like cash ones. No money arrives and the tax is still payable.
- The recommendation: Add every reinvested distribution to your cost base as you go, or you will pay tax twice on the same amount when you eventually sell.
Where the AI summary above gets this wrong
"You only pay tax on a managed fund when you sell it."
That's surface-true. Here's what it misses:
- Distributions are taxed every year — The fund attributes its income and realised gains to you annually, whether you take them in cash or reinvest them.
- Reinvestment does not defer anything — A reinvested distribution is taxed as though it were paid to you and then used to buy more units, because that is legally what happened.
01 What a distribution contains
An annual distribution statement breaks the amount into components: interest, unfranked dividends, franked dividends with their franking credits, discounted and other capital gains, foreign income with any foreign tax paid, and tax-deferred amounts.
Each component is taxed under its own rules in your return. Franking credits are added to income and then offset against the tax payable; discounted capital gains are grossed up and then reduced by the CGT discount.
Tax-deferred amounts are not taxed on receipt but reduce your cost base, which increases the capital gain when you eventually sell. They defer, they do not exempt.
The distribution components differ from what a directly held share portfolio produces mainly in the presence of that attributed capital gain — the comparison is in the distributions post.
02 Why a falling fund can still tax you
The capital gains component reflects what the manager sold inside the fund during the year, not what happened to the unit price. A manager rebalancing out of a long-held position realises a large gain regardless of the fund's return that year.
That is why a fund can fall in value and still distribute a taxable capital gain. Investors who bought late in the year receive an attribution for gains accrued before they arrived.
Buying a fund shortly before its distribution date exposes you to exactly that: you receive a distribution that is largely a return of your own capital, and it is taxable.

03 Keeping the cost base right
Every reinvested distribution buys units at a price, and that price is the cost base of those units. Failing to record it means the eventual sale calculation treats the reinvested amount as gain, taxing it a second time.
Tax-deferred components reduce the cost base of your existing units and must be tracked separately from the reinvestment purchases.
Losses realised on sale can be carried forward indefinitely against future gains, which is what makes the record-keeping worth the trouble — the mechanics are in the capital losses reference.
Shows: the tax payable on an annual distribution split into its franked, unfranked and discounted capital gain components. Ignores: the Medicare levy, foreign income and tax offsets, and tax-deferred amounts.

The one that catches people is buying a fund in May and receiving a June distribution that is mostly a return of the money they just put in — and paying tax on it. If you are making a large purchase near the end of the financial year, ask when the distribution date is.
FAQ
How are managed funds taxed in Australia?
The fund attributes its income and realised capital gains to unit holders each year. Each component — interest, franked and unfranked dividends, capital gains — is taxed under its own rules in your return.
Am I taxed if I reinvest the distribution?
Yes. A reinvested distribution is taxed as though it were paid to you and used to buy more units, which is legally what happened. Add the reinvested amount to your cost base.
Can a fund that fell in value still create a tax bill?
Yes. The capital gains component reflects what the manager sold inside the fund, not the unit price. A rebalance can realise a large gain in a year the fund fell.
