Trading and prop firm income on a 1099-NEC typically carries 15.3% self-employment tax. An S-Corp's salary-plus-distribution split can trim thousands off that layer — see what the math could look like for your numbers in about 60 seconds.
For most profitable traders, an S-Corp typically trims $3,000–$15,000 per year off self-employment tax. The savings come from paying SE/payroll tax on a reasonable salary only, instead of on every dollar of net income — distributions typically skip the 15.3% layer entirely. Every situation varies.
| Net SE Income | Sole-Prop SE Tax | S-Corp Payroll Tax* | Est. Savings† |
|---|---|---|---|
| $60,000 | $8,478 | $4,239 | ~$2,739 |
| $80,000 | $11,304 | $5,652 | ~$4,152 |
| $120,000 | $16,955 | $8,478 | ~$6,978 |
| $150,000 | $21,194 | $10,597 | ~$9,097 |
*On a reasonable salary modeled at half of net income, capped at $80,000. †Net of ~$1,500/yr typical S-Corp admin — payroll, extra return, state fees vary. Simplified: applies the full 15.3% under the Social Security wage base ($184,500 for 2026); the 12.4% portion stops above it, while the 2.9% Medicare portion has no cap. The election itself is filed on IRS Form 2553.
The savings are real for most traders above the break-even, but an S-Corp is a real business structure with real upkeep — non-scary, just worth going in with open eyes:
For most profitable traders with self-employment income, typically $3,000–$15,000 per year. The savings come from paying the 15.3% SE/payroll tax on a reasonable salary only instead of on every dollar of net income — distributions typically skip that layer. Every situation varies.
The IRS expects S-Corp owners to take a salary comparable to what similar work would pay. Many trader S-Corps land near a 50/50 salary-to-distribution split — this calculator models salary as half of net income, capped at $80,000. A CPA typically documents the number with comparable-pay data.
Typically around $80,000+ in net self-employment income. Below roughly $60,000–$80,000 net, the SE-tax savings usually don't clear the real-world $1,500–$3,000+ per year in payroll, bookkeeping, and separate-return costs (this calculator models a $1,500 baseline). Above that level the savings typically outpace overhead quickly — every situation varies, which is why most traders model it before electing.
Prop firm traders with 1099-NEC payouts are typically strong candidates, because payouts are self-employment income. Personal-account traders are different — capital gains aren't subject to SE tax, so an S-Corp usually helps only where trader tax status and entity structure create earned income. A trader-specialist CPA typically sorts out which bucket applies.
Entity setup packages typically include state LLC formation, EIN registration, the S-Corp election paperwork (IRS Form 2553), and operating-agreement basics — with a TraderTax-matched CPA reviewing whether the election actually fits before anything is filed. Packages start at $297 plus state fee; see the entity setup page for tiers.
