CFD and Forex Tax in Australia: Why You Never Get the 50% Discount

Two Australians make the same $20,000 profit on the same index over the same fourteen months. One bought the shares. One traded a CFD over them. The share investor halves their taxable gain. The CFD trader does not, and never will, no matter how long the position stays open.

That is not a loophole anyone is missing. It is structural, it comes from a taxation ruling written in 2005, and it is the single most misunderstood fact about trading in Australia. This guide sets out how the ATO actually treats CFDs and retail forex, what the treatment costs you, the one real advantage it hands back, and where the investor-versus-trader line sits.

This is the tax guide the Trading in Australia hub points at.

Revenue account, and what that means

Under taxation ruling TR 2005/15, the ATO generally assesses CFD trading as a profit-making activity carried on with the intention of profit. That places it on revenue account rather than capital account, with two consequences that define everything else.

• Profits are ordinary income, taxed at your marginal rate, in the year they are derived.
• Losses are generally deductible against other ordinary income, subject to the non-commercial loss rules.

The reason is not arbitrary. A CFD is a derivative contract settled in cash against a reference price. You never acquire the underlying currency, share, index or commodity. Without an underlying capital asset there is nothing for capital gains treatment to attach to, and so no CGT discount can apply – the discount is a concession on the disposal of an asset you owned for more than twelve months, and you owned nothing.

Illustrative only, ignoring the Medicare levy, other income, and any offsets. The point is not the exact figures. It is that the instrument, not the holding period, decided the outcome – and it decided it by a factor of two.

What the treatment gives back

Revenue account is not purely a penalty, and the compensation is genuinely valuable to a trader who is still learning.

A capital loss on shares can only be offset against capital gains, and carried forward until you have some. A CFD loss on revenue account is generally deductible against other ordinary income in the same year – salary included. A trader who loses $15,000 on CFDs and earns a salary may reduce assessable income by that amount, rather than banking a capital loss against gains that may never arrive.

The constraint is the non-commercial loss rules, which can defer a loss from an activity that does not meet certain tests of commerciality or scale. This is exactly the point where general guidance stops being useful and a tax agent starts, because the answer turns on your income, the structure and how the activity looks in aggregate.

Share trader or share investor?

The parallel question for anyone trading shares directly rather than derivatives, and the one where people assume the wrong answer is the better one.

The ATO weighs the whole activity: commercial purpose and character, intention to make a profit, repetition and regularity, organisation in a businesslike way with proper records, and the scale of the operation. There is no trade count, no holding period and no dollar figure that settles it.

Being assessed as a share trader means shares are trading stock, profits are ordinary income and losses are deductible – and the 50% CGT discount is gone. Being a share investor means capital treatment, the discount on assets held beyond twelve months, and capital losses quarantined against capital gains.

For a profitable long-horizon holder, trader status is a downgrade. People pursue it believing it sounds more professional, and pay for the privilege.

What changes on 1 July 2027

Changes announced in the 2026–27 Federal Budget replace the 50% CGT discount with cost base indexation plus a minimum tax on capital gains, from 1 July 2027. The ATO has confirmed the changes do not affect Tax Time 2026, and gains accrued before that date are reported as keeping the existing treatment.

The irony for readers of this page: CFD traders lose nothing, because they were never getting the discount in the first place. The change lands on long-term share investors, which narrows the gap between the two regimes from the other direction. Verify the legislated detail before acting on it – announced is not enacted, and the mechanism matters.

Records the ATO expects

• Every closed position with dates, amounts and the AUD value.
• Financing and commission charges, which form part of the calculation rather than a separate deduction.
• Platform, data and subscription costs, which are deductible against revenue-account income and which most traders forget to claim.
• Broker statements downloaded at the time. Platforms change and accounts close.

Where this sits in Mind, Method, Money

This is Money. A tax difference of that size dwarfs the edge most retail strategies produce, and it is decided before the first trade by a choice most people make on the basis of which tab the broker opened by default. The trader who spends six months on entries and no time on classification is optimising the small number.

Frequently asked questions

Do I pay CGT on CFD profits in Australia?

Generally no – CFD profits are normally assessed as ordinary income on revenue account under TR 2005/15, taxed at your marginal rate. Because there is no underlying asset, the capital gains rules and the 50% discount do not apply regardless of holding period.

Can I claim CFD losses against my salary?

Often yes, because revenue-account losses are generally deductible against other ordinary income in the same year, unlike capital losses. The non-commercial loss rules can defer that deduction, which is why this one deserves a registered tax agent rather than a forum.

How is retail forex taxed in Australia?

Retail forex trading through a CFD or margin product is treated the same way – ordinary income on revenue account. Holding actual foreign currency long term can fall under different rules, but that is uncommon for retail traders.

Is it better to be classified as a share trader?

Usually not, if you are profitable and hold positions beyond twelve months, because trader status converts discountable capital gains into fully taxed ordinary income. It helps when losses need to be deductible against other income.

Does the 2027 CGT change affect CFD traders?

No, because CFD traders never had the 50% discount. The announced change from 1 July 2027 affects investors holding capital assets beyond twelve months.
