Prop firm payouts: 1099-NEC, not 1099-B

Prop payouts are contractor income, not capital gains

Prop firm tax structure trips up new traders constantly. You pass a challenge, hit your profit target on the firm's account, and get a payout. Where does that money show up on your taxes? Not where you'd guess. Quick disclaimer: this is education, not tax advice. Talk to a CPA.

Here's the structural reason. When you trade your own brokerage account, you own the positions. The broker reports your sales on Form 1099-B, you fill out Form 8949, and capital gains rules apply. At a prop firm, you do NOT own the positions. The firm owns the account. You're effectively a contractor running their book in exchange for a profit share. So your payout is fee-for-service income, not a capital gain. It comes on Form 1099-NEC (non-employee compensation), and it flows to Schedule C as self-employment income.

Why does this matter? Two big reasons. One: capital gains rates can be lower than ordinary income rates, especially for high earners. A prop trader misses out on the 60/40 split that a Section 1256 futures trader gets. Two: self-employment tax (the combined Social Security and Medicare portion) adds about 15.3% on top of regular income tax, up to the wage base. That can be a meaningful chunk of your payout if you weren't expecting it.

The upside: as a Schedule C filer, you can deduct legitimate business expenses against your prop payouts. Challenge fees, data subscriptions, education, a portion of your home office and equipment if it qualifies. None of those are deductible against personal-brokerage capital gains for most retail traders (you'd need full 'trader tax status' under Section 475(f), and prop traders don't qualify because you don't own the positions). Discuss with a CPA what's legitimately deductible in your situation.

Recap: prop payouts come on 1099-NEC and go on Schedule C as self-employment income. Subject to SE tax. Business expenses are deductible. Different game from personal brokerage. Not tax advice.
