Prop Firm Australia Tax: What the ATO Expects From You

If you are an Australian resident earning payouts from a prop firm, the Australian Taxation Office (ATO) wants its share. Your payouts are almost certainly classified as ordinary income, not capital gains, which means they get added to your assessable income and taxed at your marginal rate. There is no trader-friendly loophole hiding in the tax code.

How the ATO Classifies Prop Firm Income

The ATO looks at prop firm payouts and sees assessable income. Not a capital gain. Not a windfall. Not a friendly gift from a company in Prague. Assessable income, earned through a trading activity that looks, walks, and quacks like a business.

Why does this matter? Because ordinary income gets taxed at your full marginal rate — up to 45% plus the 2% Medicare levy at the top bracket. If you were hoping for the 50% CGT discount that applies to assets held longer than 12 months, I have bad news. The ATO has clear tests for determining whether your activity is a business or an investment, and funded prop traders tick every box for "business."

Important: I am not a registered tax agent. Nothing in this article constitutes financial or tax advice. Speak to a registered tax agent who understands trading income before lodging your return. You can find official guidance directly from the ATO Business or Hobby page and the ATO GST Registration page. This is informational only.

Trading Business vs Hobby vs Capital Gains

The ATO classifies trading activity into three categories, and the one you fall into determines how your payouts get taxed. Here is the breakdown:

1. Carrying on a business (most funded traders)

If you trade regularly, use systematic strategies, spend significant time on analysis and execution, and intend to make a profit, the ATO considers you to be carrying on a business. Your prop firm payouts are ordinary assessable income.

2. Hobby (very rare for funded traders)

If you trade occasionally, make little to no profit, and do not approach it in a business-like manner, the ATO may consider it a hobby. Hobby income is not assessable. But here is the catch: if you passed a prop firm challenge and are receiving regular payouts, the ATO will almost certainly classify this as a business, not a hobby.

3. Capital gains (almost never applies to prop traders)

Capital gains tax (CGT) applies when you dispose of a CGT asset. Prop firm funded traders do not own the capital in their accounts. You are not buying and holding assets. You are receiving a share of profits generated on a simulated or firm-owned account. There is no CGT asset to dispose of, which makes the capital gains argument extremely weak.

The ATO published Taxation Ruling TR 2006/2 which discusses whether a taxpayer is carrying on a financial services business. Key factors include the volume and regularity of transactions, the amount of capital employed, and whether the activity is organised in a business-like way. Funded prop traders typically satisfy all of these indicators.

Do You Need an ABN for Prop Trading?

An Australian Business Number (ABN) is not strictly required for all prop traders, but in most cases you should get one. Here is why.

If the ATO classifies your prop trading as carrying on a business — and for most funded traders it will — then you are effectively a sole trader. Registering for an ABN is free, takes about 15 minutes online, and makes your tax life significantly easier.

Benefits of having an ABN as a prop trader:

• You can register for GST if your turnover exceeds $75,000 (required by law)
• You can claim deductions against your prop firm income more easily
• Your tax return is cleaner — business income reported properly as sole trader income
• Some prop firms may request an ABN for their own invoicing records

You register for an ABN through the Australian Business Register (ABR). Select "sole trader" as your business structure. Your business activity is trading or financial services.

If you only trade occasionally and earn small amounts, you may not need an ABN. But if you are receiving regular payouts from a funded account, the ATO will expect you to be operating as a business, and having an ABN demonstrates that you are treating it as one.

Tax Rates for Australian Prop Traders

As a sole trader earning ordinary income from prop firm payouts, you pay tax at individual marginal rates. Your prop firm income is added to any other income you earn (salary, investments, etc.) and taxed accordingly.

Here are the Australian individual income tax rates for 2025-26:

On top of these rates, add the 2% Medicare levy. So at the top bracket, you are effectively paying 47% on every extra dollar earned. Not including the Medicare Levy Surcharge if your income is high enough and you do not have private health insurance.

Here is a practical example. Say you earn $90,000 from your day job and $40,000 from prop firm payouts. Your total taxable income is $130,000 (assuming minimal deductions). The $40,000 in prop firm income falls in the 30% bracket, meaning you lose roughly $12,000 of it to tax, plus Medicare levy.

GST Registration and BAS Obligations

This is where prop trading gets administratively annoying in Australia. If your annual turnover from prop trading exceeds $75,000 AUD, you must register for Goods and Services Tax (GST).

The $75,000 threshold is based on your GST turnover — basically your gross revenue from business activities. If you earn $80,000 in prop firm payouts, you exceed the threshold and must register within 21 days.

What GST registration means for prop traders:

• You must lodge a Business Activity Statement (BAS) — usually quarterly, sometimes monthly
• You charge GST on your services (10% of your revenue)
• You can claim GST credits on business purchases
• Your BAS reports both GST and your PAYG instalments (if applicable)

Most part-time funded traders earn well below $75,000 per year from prop payouts and do not need to register. If you are in this camp, you can skip GST entirely.

If you do exceed the threshold, register through the ATO online services portal or through your myGov linked ATO account. You will receive a GST-registered ABN and BAS reporting obligations from that point forward.

One important note: whether prop firm payouts count as a "taxable supply" for GST purposes depends on the specific arrangement. Some tax agents argue that receiving a profit share from an overseas entity may not constitute making a taxable supply in Australia. This is an area where professional advice is essential.

PAYG Instalments: Quarterly Tax Payments

The ATO does not wait until tax time to collect your money. If you earn business or investment income above certain thresholds, the ATO requires you to pay tax in quarterly instalments through the Pay As You Go (PAYG) system.

You enter the PAYG instalment system when:

• The ATO estimates your tax liability on business or investment income will exceed $500 for the year, and
• You lodged a previous tax return showing notional tax of more than $500

The ATO calculates your instalment amount based on your previous year's tax return. They send you a notice with the quarterly amount, and you pay it via BAS or directly through your myGov account.

Quarterly due dates:

• Q1 (July–September): 28 October
• Q2 (October–December): 28 February
• Q3 (January–March): 28 April
• Q4 (April–June): 28 July

If you miss PAYG instalments, the ATO charges interest at their general interest charge rate, which compounds daily. It is not worth the headache. Set aside 25-30% of every payout into a separate account so the money is ready when the BAS is due.

This is similar to the quarterly instalment system in Canada, but the thresholds and mechanics are different.

Deductible Expenses for Australian Prop Traders

Operating as a sole trader means you can deduct business expenses from your assessable income. Every legitimate dollar you claim reduces your tax bill. Here is what you can and cannot deduct:

Generally deductible expenses:

• Challenge fees: The cost of evaluations, including failed challenges and resets, are business expenses
• Reset fees: Account resets you paid for
• VPS hosting: Server costs for EA hosting or low-latency execution
• Data feeds and subscriptions: Market data, charting platforms like TradingView, news services
• Platform fees: Monthly platform or license fees charged by the prop firm
• Internet: The business portion of your internet costs
• Home office: Dedicated workspace expenses — occupancy costs, utilities, depreciation on equipment
• Computer equipment: Monitors, laptops, peripherals — deductible immediately if under $300, depreciated if over
• Educational materials: Trading courses, books, subscriptions related to your trading business
• Accounting and tax agent fees: The cost of getting professional tax help is itself deductible

What you cannot deduct:

• Personal time or labour
• Losses from the funded account (you do not own the capital)
• Personal expenses with no business connection
• Fines or penalties (including ATO penalties)

Keep receipts for everything. The ATO requires records to substantiate your claims, and they will ask for evidence if you are reviewed.

Record Keeping: What the ATO Expects

The ATO requires you to keep business records for five years from the date you lodge your tax return. For most prop traders, that means keeping everything related to your trading business for at least five years.

Records you must keep:

• Payout confirmations from the prop firm (screenshots, PDFs, emails)
• Bank statements showing payout deposits
• Receipts for all deductible expenses
• Challenge fee payment receipts
• Reset fee receipts
• VPS hosting invoices
• Data feed and subscription receipts
• Trading logs or statements from the prop firm platform
• GST records if registered (tax invoices, BAS lodgements)

I explain record keeping in more detail in our prop firm tax records guide, which covers what to keep and for how long across multiple jurisdictions.

The ATO can audit your returns up to five years back. If you cannot produce records to support your income and expense claims, they can disallow deductions and issue amended assessments with penalties and interest. Five years of records is non-negotiable.

Common Tax Mistakes Australian Prop Traders Make

These are the mistakes I see repeatedly in r/AusFinance and prop trading communities. Do not be the person who learns these the expensive way.

• Assuming payouts are capital gains: The most common mistake. Traders assume that because they are trading financial instruments, profits must be CGT. The ATO almost never sees it that way for active prop traders. Claiming the 50% CGT discount on income the ATO classifies as ordinary income triggers an amended assessment, penalties, and interest.
• Not declaring overseas income: Most prop firms are based outside Australia. That does not exempt you from Australian tax. Australian residents are taxed on worldwide income. Every payout from every prop firm, everywhere, goes on your return.
• Ignoring PAYG instalments: The ATO sends you a notice saying you owe quarterly instalments. You ignore it because "I will sort it at tax time." The ATO charges daily compound interest on late payments. Sort it when the notice arrives.
• Not getting an ABN: If you are earning regular prop firm payouts, you are carrying on a business. Register for an ABN. It is free and it makes everything else easier.
• Poor record keeping: Not keeping receipts for challenge fees, data subscriptions, or VPS costs. Then at tax time, you cannot claim deductions and pay tax on money you already spent. Keep everything.
• Mixing personal and business finances: Prop firm payouts landing in your everyday transaction account alongside groceries and Netflix. Open a separate account for trading income and expenses.

The best investment you can make as an Australian prop trader is one session with a registered tax agent. The fee is deductible, and it can save you thousands in penalties. Do not wait until you have already lodged incorrectly for two years.
