1099 take-home: $50,000 → $39,539.11 (single)
A W-2 paycheck has an employer matching half of FICA. A 1099 / Schedule C filer pays both halves as self-employment tax (SECA), then files Form 1040 for income tax. This calculator runs both in one pass:
- SECA: 12.4% Social Security + 2.9% Medicare on 92.35% of net earnings (IRS Topic 554). Social Security stops at the $184,500 2026 wage base.
- ½ of SE tax is deductible above the line (IRC § 164(f)).
- 2026 standard deduction (Rev. Proc. 2025-32): $16,100 single / $32,200 MFJ / $24,150 HoH.
- Form 1040 §1 rate tables for 2026, not the Pub 15-T withholding tables.
This page is U.S. federal only; it is not Mexico, Colombia, or Guatemala take-home.
SECA = 12.4% × min(0.9235 × net, remaining SS wage base) + 2.9% × (0.9235 × net)
AGI = net − ½ SECA taxable = max(0, AGI − standard deduction) income tax = Form 1040 §1 lookup (Rev. Proc. 2025-32) take-home = net − SECA − income tax
Worked example: $50,000 single → $39,539.11
Single, $50,000 Schedule C net profit, no W-2 wages:
- SECA: $7,064.78 (IRS Topic 554 golden case)
- ½ SE deductible: $3,532.39 → AGI $46,467.61
- Taxable: $46,467.61 − $16,100 = $30,367.61
- Income tax: $1,240 + 12% × $17,967.61 = $3,396.11
- Take-home: $39,539.11 — about 79.1% of net profit. Quarterly estimate: $2,615.22

W-2 wages share the Social Security base
| Scenario | SE Social Security | SE Medicare | SECA total | Take-home |
|---|---|---|---|---|
| $50,000 SE only (single) | $5,725.70 | $1,339.08 | $7,064.78 | $39,539.11 |
| $50,000 SE + $180,000 W-2 SS wages | $558.00 | $1,339.08 | $1,897.08 | $44,396.75 |
With $180,000 already paid on a W-2, only $4,500 of the $184,500 2026 Social Security wage base remains for SECA. Medicare stays uncapped on the full 92.35% of Schedule C net.

1099 take-home $80,000 → $61,169.76
Single filer, no W-2 wages: SECA $7,064.78 + income tax $3,396.11 = total tax $10,460.89 → take-home $39,539.11 and a quarterly estimate of $2,615.22. Married filing jointly on the same profit keeps $41,508.46 because the $32,200 standard deduction lowers income tax to $1,426.76.
FICA is what an employer withholds from a W-2 (6.2% + 1.45% employee share, plus the employer match). SECA is what a self-employed person pays alone: 12.4% Social Security + 2.9% Medicare on 92.35% of net earnings. Half of the SE tax is deductible on Form 1040.
W-2 withholding uses the Pub 15-T percentage-method tables. A self-employed person files Form 1040, which uses the § 1 rate tables from Rev. Proc. 2025-32. They are different numbers on purpose — a $50,000 W-2 paycheck and a $50,000 Schedule C profit are not the same tax shape.
QBI (§199A), Additional Medicare Tax 0.9%, NIIT, credits, estimated-tax penalties, and state or local tax. $8,000 single still owes SECA $1,130.36 even when income tax is $0. It is an educational estimate, not tax advice.
