Prop Firm Taxes for US Traders: What You Actually Owe

I’ve seen prop firm traders ask about taxes in almost every trading community I follow, and the answers are usually wrong. “You just file a 1099” doesn’t begin to cover it. The tax treatment of prop firm income is specific, the self-employment tax hit is significant, and there are deductions most traders miss.

This guide covers federal tax treatment for US-based traders using futures prop firms like Apex, Topstep, MFF, and similar. I am not a CPA. This is educational, not tax advice. Get a professional for your specific situation.

How the IRS classifies your prop firm income

Prop firm payouts are ordinary business income, classified as self-employment income. You are an independent contractor, not an employee. The IRS doesn’t care whether your account is labeled “simulated” or “live” — they care that you received money for a service (your trading skill).

This means your prop firm income is NOT treated like capital gains from your own trading account. This distinction matters a lot, and I’ll explain why in a minute.

Do prop firms send you a 1099?

US-based firms (Apex, Topstep, Tradeify) issue Form 1099-NEC for payouts over $600. Topstep confirmed they sent 1099s via email on January 31, 2026 for the 2025 tax year.

Some firms use payment processors like Rise or Deel, which issue the 1099-NEC on behalf of the prop firm. So the 1099 might come from Rise or Deel rather than the firm itself. It’s the same income either way.

International firms (FTMO, some MFF plans) are NOT required to issue US tax forms. But — and this is critical — you must report ALL income regardless of whether you receive a 1099. Not reporting income because a foreign firm didn’t send paperwork is tax evasion. The IRS doesn’t accept “I didn’t get a form” as an excuse.

The self-employment tax hit

This is the part that surprises most traders. As an independent contractor, you pay self-employment tax on top of your regular income tax. The rate is 15.3%:

• 12.4% for Social Security (capped at roughly $168,600 in 2026)
• 2.9% for Medicare (no cap)
• Additional 0.9% Medicare surtax on income over $200,000 (single) or $250,000 (married filing jointly)

Here’s what that looks like in real numbers:

That’s BEFORE federal income tax and state income tax. A trader making $100,000 from prop firms in California is looking at roughly $14,130 in SE tax + $24,000 in federal income tax + $9,300 in CA state tax = about $47,430 total. Keep about 53 cents of every dollar.

The half-good news: you can deduct half of your SE tax from your adjusted gross income on Form 1040. It reduces your income tax slightly, but it doesn’t eliminate the SE tax itself.

Why prop firm income gets worse tax treatment than your own account

If you trade futures in your OWN brokerage account, you get Section 1256 contract treatment. This means 60% of your gains are taxed at long-term capital gains rates (currently 15-20%) and 40% at short-term rates (your ordinary income rate). This is a significant tax advantage.

Prop firm income doesn’t get Section 1256 treatment. It’s all ordinary income. All of it taxed at your marginal rate plus 15.3% self-employment tax.

Example on $100,000 in futures trading profits (single filer, no other income):

Own account (Section 1256):

• 60% ($60,000) at 15% LTCG = $9,000
• 40% ($40,000) at 22% ordinary = $8,800
• SE tax: $0
• Total federal tax: ~$17,800

Prop firm (ordinary + SE):

• 100% at ordinary income rates: ~$17,400
• SE tax: ~$14,130
• Total federal tax: ~$31,530

That’s almost $14,000 more in taxes on the same $100,000 in profits. The self-employment tax alone nearly doubles the federal tax bill.

This is one of the strongest financial arguments for transitioning to trading your own capital once you’ve built enough. The tax savings on $100K+ in annual trading income are massive.

What forms you need to file

• Form 1099-NEC: You’ll receive this from prop firms or their payment processors for payouts $600+
• Schedule C (Form 1040): Report all prop trading income and deduct business expenses
• Schedule SE (Form 1040): Calculate your 15.3% self-employment tax
• Form 1040-ES: Quarterly estimated tax payment vouchers
• Form 1040: Your main annual tax return

On Schedule C, use Business Activity Code 523910 (Miscellaneous Intermediation) or 523130 (Commodity Contracts Dealing).

Important: the 1099-NEC reports your GROSS payout amount (before processing fees). Deduct fees separately on Schedule C. Don’t accidentally pay tax on the $30 withdrawal fee Topstep charged.

What you can deduct

As a self-employed trader, your business expenses reduce your taxable income. These are all deductible on Schedule C:

100% deductible:

• Evaluation/challenge fees — even the ones you FAILED
• Reset fees and re-entry fees
• Monthly subscription/data fees from prop firms
• Rithmic data feed ($85/month or $140 lifetime)
• Trading platform licenses (NinjaTrader, etc.)
• Market data subscriptions (CME, etc.)
• VPS or cloud hosting for trading
• Trading education (courses, mentorship, books)
• Computer hardware and monitors (Section 179 depreciation or spread over useful life)
• Professional services (CPA, tax advisor, legal counsel)
• Payout processing fees ($30 per Topstep withdrawal, Deel fees, etc.)

Partially deductible:

• Internet service — only the business-use percentage
• Home office — two methods available:
  • Simplified: $5 per square foot, max 300 sq ft = $1,500 max deduction
  • Regular: actual percentage of rent/mortgage interest, utilities, insurance based on square footage of dedicated trading space
• Cell phone — business-use percentage only

One thing traders miss: failed evaluation fees are deductible. If you spent $2,000 on evaluations you didn’t pass, that’s a $2,000 business expense that reduces your taxable income. Keep records of every evaluation purchase.

What you CANNOT deduct

Trading losses inside funded accounts are NOT deductible. It’s the firm’s capital, not yours. You didn’t lose your own money, so there’s no loss to claim. No capital loss deductions. No $3,000 annual offset. This is a meaningful difference from trading your own account, where losses can offset gains.

Wash sale rules also don’t apply to prop firm trading, since these aren’t your capital gains or losses. Small silver lining.

Quarterly estimated taxes

If you expect to owe $1,000 or more in taxes for the year, the IRS requires quarterly estimated payments. Miss them and you’ll owe penalties and interest even if you pay everything at year-end.

2026 due dates:

• Q1: April 15, 2026
• Q2: June 15, 2026
• Q3: September 15, 2026
• Q4: January 15, 2027

Safe harbor rule: Pay at least 90% of your current year tax liability OR 100% of your prior year liability (110% if your AGI exceeds $150,000). Meet either threshold and you won’t owe penalties even if you underpay slightly.

My recommendation: set aside 25-30% of every prop firm payout into a separate savings account earmarked for taxes. When quarterly payments come due, you have the money ready. Don’t spend your gross payouts and scramble for tax money later.

State taxes

State income tax applies on top of everything above. The impact varies enormously:

No state income tax (best for traders): Texas, Florida, Nevada, Wyoming, Washington, South Dakota, Alaska, Tennessee, New Hampshire (limited to interest/dividends)

Highest state tax burden: California (up to 13.3%), New York (up to 10.9%), New Jersey, Oregon, Minnesota

If you’re a prop firm trader making $100K+, your state of residence can cost or save you $5,000-$13,000 per year in taxes. Some full-time traders relocate specifically for this reason.

Some states also require separate quarterly estimated state tax payments.

Entity structure: when to form an LLC or S-Corp

For income under $50,000/year, file as a sole proprietor. The simplicity isn’t worth giving up for the marginal benefits of an entity.

For income between $50,000-$80,000, a single-member LLC provides liability protection with the same tax treatment. Worth the small filing cost.

For income consistently above $60,000-$80,000/year, an S-Corp election can save significant money on self-employment tax. Here’s how it works:

As a sole proprietor making $120,000, you pay SE tax on all $120,000 (~$16,956).

As an S-Corp, you split the $120,000 into a “reasonable salary” of $60,000 (which you pay SE tax on) and $60,000 in distributions (no SE tax). SE tax drops to ~$8,478. You save roughly $8,478 per year.

The “reasonable salary” has to be defensible — the IRS will question a $120K earner paying themselves a $30K salary. Work with a CPA to find the right split.

Note: Topstep specifically does NOT allow C-Corp, S-Corp, or multi-member LLC accounts. Check each firm’s entity requirements before restructuring.

The constructive receipt trap

One last thing. Income is taxable when it’s available to you, not when you withdraw it. If your prop firm credits $5,000 to your payout balance and you choose not to withdraw it, the IRS may still consider that income in the year it was credited. This is the “constructive receipt” doctrine.

In practice, most prop firms require you to actively request a payout, which means income is recognized when the payout is processed. But if a firm’s system credits money directly to an external wallet or account you control, it may be taxable immediately.

When in doubt, recognize income in the year the payout is processed. Don’t try to defer by leaving money in the firm’s system — it creates ambiguity you don’t want during an audit.

Summary: your tax checklist

1. Set aside 25-30% of every payout for taxes
2. Track ALL expenses (eval fees, data feeds, platforms, home office)
3. Make quarterly estimated payments (April, June, September, January)
4. File Schedule C and Schedule SE with your 1040
5. Report all income even if you don’t receive a 1099
6. Consider S-Corp election if consistently earning $60K+
7. Consider relocating to a no-income-tax state if earnings justify it
8. Hire a CPA who understands trader taxation (Green Trader Tax is a good resource)

The tax bill on prop firm income is the ugliest part of the business. Self-employment tax plus ordinary income rates plus state tax can take 40-50% of your gross payouts. Knowing this upfront and planning for it is the difference between a sustainable trading business and a surprise bill in April.
