Crypto prop firm tax handbook (US, UK, BR, AU)

Prop firm payouts are not capital gains. In all four jurisdictions covered here they are treated as earned income, trading income, or foreign-source financial income — categories that are taxed differently (and usually higher) than crypto held as an investment. The structural misconception drives more tax trouble than any other single mistake funded traders make.

The structural question: payouts are not capital gains

When you trade on your own exchange account, your gains may be taxed as capital gains depending on jurisdiction and holding pattern. When you trade a prop firm's capital and receive a payout, you are being paid for providing a service — trading skill applied to their balance sheet. Every tax authority covered in this guide has converged on the same interpretation: prop firm payouts are ordinary / trading / foreign-source income, not capital gains.

The practical consequence: your effective rate is higher than you would pay on long-term crypto capital gains, and you may owe self-employment or trading-related surcharges that don't apply to passive investment. Budget accordingly.

United States — 1099-NEC, Schedule C, and the OBBBA threshold change

Summary for US-resident funded traders (2026): prop firm payouts are classified as nonemployee compensation — ordinary income, not capital gains. US-domiciled firms report on Form 1099-NEC (threshold $2,000 starting tax year 2026 under the One Big Beautiful Bill Act, up from $600). Reportable regardless of 1099 receipt. Filed on Schedule C of Form 1040 as sole-proprietor business income. Federal income tax applies at your marginal rate, and self-employment tax adds 15.3% on the first $168,600 of net earnings (Social Security 12.4% + Medicare 2.9%), plus 0.9% Medicare surtax above $200K single / $250K MFJ. Quarterly estimated payments on Form 1040-ES are required if annual liability exceeds $1,000. Foreign prop firms don't issue 1099s but payouts remain reportable. Statutory basis: IRC §§ 61, 1401, 6654. (IRS, OBBBA 2026.)

US-domiciled prop firms classify funded traders as independent contractors. Your payouts flow through Form 1099-NEC (nonemployee compensation), which you report on Schedule C as sole-proprietor business income. Two taxes stack on top.

Income tax at your marginal federal rate (plus state, if applicable) on net business profit. Self-employment taxat 15.3% on the first $168,600 of net earnings in 2026 — that's 12.4% Social Security + 2.9% Medicare. An additional 0.9% Medicare surtax applies above $200,000 single / $250,000 married filing jointly. Self-employment tax is the number that catches most traders off guard; it's what your employer would normally pay as the employer-side FICA, and now you owe both halves.

The 2026 threshold change (OBBBA)

Under the One Big Beautiful Bill Act, the reporting threshold for 1099-NEC filings rises from $600 to $2,000 starting in tax year 2026. If you earn less than $2,000 from a given firm, they no longer send you a 1099. Per IRS guidance, this does not change your reporting obligation — you still must declare all payouts — but it does reduce the paper trail. Traders who file only what they receive 1099s for will under-report.

Quarterly estimated payments

If you expect to owe $1,000+ in federal tax for the year, the IRS requires quarterly estimated payments on Form 1040-ES. The quarters end April 15, June 15, September 15, and January 15. Underpayment triggers a penalty regardless of whether you pay the full amount at filing. For a trader pulling $50K+ in annual payouts, this is not optional.

Foreign prop firms and US traders

Most of the firms we cover are not US-domiciled: HyroTrader (Estonia), FundedNext (multiple), FTMO (Czechia), BrightFunded (Netherlands), FundingPips (UAE). When you trade with a foreign firm, you generally don't receive a 1099, and your bank may not flag the incoming payout as trading income. This changes nothing about your tax obligation. Every payout is reportable on Schedule C regardless of paper trail; the IRS considers foreign prop firm income equivalent to domestic prop firm income for reporting purposes. For payouts over $10,000 in aggregate foreign accounts, you also have FBAR (FinCEN 114) and potentially Form 8938 obligations — separate filings from your 1040.

Deductible expenses on Schedule C

• Challenge fees — every fee paid to attempt a prop firm evaluation, including reset fees and retry discounts.
• Platform subscriptions — TradingView, NinjaTrader, data feeds, execution platforms not covered by the prop firm.
• Hardware — multiple monitors, dedicated trading computer, networking equipment allocated to trading use.
• VPS / execution infrastructure — any server running your execution bots or copy-trade infra.
• Trading education — courses, mentorship, books directly related to your trading strategy.
• Home office — proportional rent, utilities, and internet if you have a dedicated trading workspace.

United Kingdom — the badges of trade, MTD for ITSA

Summary for UK-resident funded traders (2026/27): HMRC classifies systematic funded-trader income as trading income under the badges of trade framework (BIM20205) — not capital gains. Gross trading income exceeding £1,000 per tax year (the trading allowance threshold) triggers mandatory Self Assessment registration and SA100 filing by 31 January following the 5 April year-end. Income tax applies at marginal rates 20/40/45% alongside Class 2 and Class 4 National Insurance Contributions on trading profits. From April 2026, Making Tax Digital for Income Tax Self Assessment (MTD for ITSA) mandates quarterly digital updates via HMRC-recognised software for traders whose combined self-employment and property gross income exceeds £50,000; the £30K threshold follows in April 2027. Challenge fees, reset fees, platform subscriptions, and VPS costs are allowable business expenses if wholly and exclusively incurred for the trade. Statutory basis: ITTOIA 2005 Pt 2; FA 2022 s 62. (HMRC BIM20205; MTD for ITSA guidance.)

HMRC's foundational test for funded-trader income is the badges of trade framework. The nine badges assess: the profit motive, frequency of transactions, nature of the asset, existence of supplementary work, length of ownership, financing method, modifications to the asset, transaction method, and supplementary activity pattern. For a funded trader taking regular, systematic payouts with an explicit profit motive, the result is almost always the same: this is a trade, not passive investment.

That classification has concrete consequences. Payouts are trading income, not capital gains. Self-employment income rules apply. Income Tax rates are 20% (basic), 40% (higher), and 45% (additional). National Insurance Contributions (Class 2 and Class 4) apply on top. Crypto held as an investment enjoys a Capital Gains Tax annual exemption; trading income does not.

Self Assessment registration

If your gross trading income exceeds £1,000/year, you must register for Self Assessment and file an SA100 return. The deadline is 31 January following the tax year end (5 April). Most funded traders blow past the £1K threshold within one or two successful payouts.

Below £1,000, the trading allowance lets you keep the income tax-free without filing. This is rarely the case for serious funded traders but applies to occasional payouts from a small evaluation.

Making Tax Digital for ITSA — April 2026

From April 2026, individuals with combined gross income from self-employment and property exceeding £50,000 fall under Making Tax Digital for Income Tax Self Assessment (MTD for ITSA). The obligations: quarterly digital updates of income and expenses through HMRC-recognised software, plus an End of Period Statement and Final Declaration. The £30K threshold follows in April 2027 and the £20K threshold in April 2028.

Allowable expenses on Self Assessment

The test is “wholly and exclusively” incurred for the trade. Deductible items mirror the US list: challenge fees, reset fees, TradingView and data subscriptions, VPS costs, dedicated hardware (via capital allowances), home office proportional costs, trading courses directly supporting the strategy. Mixed-use items (phone, internet, personal laptop also used for trading) get a reasonable business-use percentage.

Brazil — Lei 14.754/2023 and the anti-deferral regime

Summary para residentes fiscais no Brasil (2026): sob a Lei 14.754/2023 (vigente desde 1º de janeiro de 2024), rendimentos de prop firms estrangeiras são classificados como aplicação financeira no exterior — não ganho de capital. Apuração anual obrigatória em 31 de dezembro a alíquota fixa de 15% sobre o resultado positivo, independente de repatriação — o regime anti-diferimento substituiu a tributação diferida anterior. Prejuízos compensáveis apenas com ganhos de outras aplicações financeiras no exterior no mesmo ano, com carryforward limitado à mesma classe. Taxas de desafio e fees de plataforma reduzem o resultado apurado. Declaração na DAA (IRPF) ficha Rendimentos Sujeitos à Tributação Exclusiva/Definitiva; saldos acima de R$ 300.000 em contas no exterior exigem CBE separada no Banco Central. Base estatutária: Lei 14.754/2023; IN RFB 2.180/2024. (Receita Federal; Banco Central do Brasil.)

Brazil rewrote foreign-asset taxation with Lei 14.754/2023, effective 1 January 2024. The law applies to all Brazilian tax residents holding financial assets abroad — including crypto on foreign exchanges and, critically for our readers, prop firm payouts from any non-BR firm.

The anti-deferral regime

Before Lei 14.754, Brazilians could defer taxation on foreign financial income until the proceeds were repatriated. The new law eliminates that deferral. Positive results are assessed annually on 31 December at a flat 15% rate, regardless of whether the funds were brought back to Brazil. The obligation is settled at the Declaração de Ajuste Anual (annual IRPF filing) the following April.

Loss compensation

Losses from foreign financial applications can be offset against gains from other foreign financial applications within the same year, per Instrução Normativa RFB 2.180/2024. Losses that exceed same-year gains can be carried forward to future years but only against the same asset class — foreign financial losses cannot offset Brazilian-source income.

Crypto-specific treatment

Crypto held on a foreign exchange (Bybit, Kraken, Binance international) falls under the new rule as foreign financial application. If you're trading via a prop firm that uses foreign exchange execution, the payout stream and the underlying crypto disposals both attach to this regime. Brazilian-domiciled exchanges (Mercado Bitcoin, Foxbit) operate under the older domestic rules (monthly DARF, progressive rates up to 22.5%) — but that's not where prop firm trading happens.

IRPF reporting

In the annual IRPF (Declaração de Ajuste Anual), foreign application results appear under the Rendimentos Sujeitos à Tributação Exclusiva/Definitiva ficha. Balances held in foreign accounts over R$ 300,000 also require Banco Central CBE (Capitais Brasileiros no Exterior) reporting, separate from the IRPF. The BC CBE has its own annual and quarterly schedules.

Australia — PSI rules, ABN, and CGT on stablecoin payouts

Summary for AU-resident funded traders (2026): prop firm payouts are ordinary income, generally classified by the ATO as either personal services income (PSI) under Division 84 of ITAA 1997 or business income, depending on whether the activity meets the personal-services-business (PSB) tests. Marginal rates apply (up to 45%) plus the 2% Medicare levy. Foreign-firm payouts are taxable in the same way — Australian residents are taxed on worldwide income. Crypto received as payment (USDT/USDC) is acquired at its AUD market value on receipt and is then subject to CGT on subsequent disposal.

PSI vs business income classification

Single-trader funded accounts where the income is substantially the reward for one person's personal skill default to personal services income. The PSI regime prevents income-splitting and limits deductions to those directly related to the work. Traders who meet the PSB tests (results test, unrelated clients test, employment test, or business premises test) can shift to business income classification, which restores normal small-business deduction rules and access to structures like discretionary trusts. Most retail funded traders fall on the PSI side; passing PSB requires evidence of unrelated “clients” — typically traders who run accounts at multiple firms with different terms.

ABN, GST, and PAYG

An Australian Business Number (ABN) is strongly recommended once annual payouts exceed AU$ 18,200 (the tax-free threshold) and effectively required above AU$ 75,000 — the GST registration threshold. Note: prop firm income is generally input-taxed financial supply, so GST is not charged on payouts even when registered; the ABN exists for income-reporting purposes. PAYG instalments apply quarterly once a tax return shows $1,000+ of taxable income — the ATO will issue activity statements automatically.

CGT on stablecoin payouts

When USDT or USDC arrives in your wallet as payout, the AUD spot value on receipt becomes both your income basis (taxed as ordinary income that year) and your CGT cost base for the stablecoin. Subsequent disposal — selling to AUD, swapping to another crypto, or spending — triggers a capital event with gain or loss measured against that cost base. Holding more than 12 months unlocks the 50% CGT discount for individuals, but for stablecoins held to fund operating expenses the gain/loss is usually negligible because the AUD value tracks the USD parity peg.

Records and references

The ATO requires records for five years from the date the return is lodged. Minimum set: ABN, every challenge fee paid (deductible against PSI/business income), every payout with AUD value at receipt date, the prop firm's terms of service, and the trading platform's monthly statements. ATO guidance on crypto assets (QC 42159) and personal services income (TR 2022/3) together govern most edge cases. Where the activity might cross into carrying on a business of trading rather than PSI, engaging a registered tax agent is the right move — the classification has flow-through consequences for losses, deductions, and superannuation contributions.

Foreign firm ≠ no tax — the universal mistake

In all four jurisdictions, the single most expensive misconception is the same: “My prop firm is based in X, so I don't owe tax here.” That is wrong everywhere.

• US: Every dollar of foreign prop firm payout is reportable on Schedule C. Absence of 1099 is not a free pass.
• UK:HMRC taxes UK-resident trading income regardless of where the firm is domiciled. The badges of trade test applies to the activity, not the counterparty's nationality.
• Brasil: Lei 14.754 was designed specifically to close the foreign-income deferral loophole. There is no longer a jurisdictional shield available to BR tax residents.
• Australia:AU residents are taxed on worldwide income. Foreign-firm payouts hit your assessable income at the AUD value on receipt; the firm's domicile is irrelevant to the ATO.

The tax authority in each jurisdiction has chain-of-custody visibility on the stablecoin rails most prop firms use: USDT/USDC on-chain flows to centralized exchanges trigger KYC disclosure at the fiat off-ramp. Assuming the income is invisible is a strategy with a short half-life.

What to track all year — minimum records

Across all three jurisdictions, the records that make tax season survivable:

• Every challenge fee paid, including reset fees and retries. Deductible in all three.
• Every payout received, with date, amount in local currency at the receipt date, and source (firm name + rail).
• Every payout's cost basis in local currency at receipt. For USDC/USDT payouts this is the spot rate when the stablecoin hit your wallet, not when you later converted to fiat.
• Every trading-related expense — TradingView, VPS, hardware, courses — with receipts.
• Quarterly running totals for US estimated-tax planning or UK MTD quarterly updates.
• Foreign account balance snapshots — US FBAR requires the high-water mark across the year; BR CBE requires a 31 December snapshot if balances exceed R$ 300K.

When DIY stops making sense

Concrete thresholds where our read is that a professional pays for themselves:

• US: Above $75K annual net prop firm income, the combination of Schedule C, quarterly estimates, SE tax, and potential state reciprocity issues (if you move states mid-year) is worth outsourcing.
• UK: The moment you cross the £50K MTD threshold, because the compliance overhead of quarterly digital filings with HMRC-recognised software usually outweighs the accountant cost.
• Brasil: Above R$ 100K annual foreign-source income, because the interaction between Lei 14.754, IN RFB 2.180, CBE reporting, and the crypto ancillary rules becomes non-trivial to compose correctly.
• Any jurisdiction:If you trade multiple prop firms in a year and any of them is domiciled in a third country you don't reside in, the reporting surface compounds quickly.
