How prop firm payouts are taxed

Most prop firms pay US traders as independent contractors and report payouts on a 1099-NEC. Nothing is withheld. Payouts minus your trading costs are self-employment income: you pay income tax on them at the rate your day job already puts you in, plus self-employment tax (Social Security and Medicare) of about 15.3% on 92.35% of the net.

Because nothing is withheld, the IRS expects you to pay during the year: quarterly estimated payments (Apr 15, Jun 15, Sep 15, Jan 15), or more withholding from your day job through a new W-4. Withholding counts as paid evenly through the year, so raising it late in the year still helps.

The 60/40 rule for Section 1256 futures contracts generally does not apply to prop firm payouts, because you are paid for a service, not for trading your own account. Confirm your situation with a CPA.
