Self-Employment Tax

SE Tax = Gross × 0.9235 × 15.3%

$85K × 0.9235 × 0.153

= $12,010

0.9235 accounts for the deductible half of SE tax. You pay both employee and employer FICA as a 1099 contractor.

Half-SE Deduction (above-the-line)

Deduction = SE Tax ÷ 2

$12,010 ÷ 2

= $6,005

The IRS lets you deduct half of SE tax before computing income tax.

Adjusted Gross Income (AGI)

AGI = Gross + Other Income − Pre-tax Deductions − ½ SE Deduction

$85K + $0 − $3K − $6K

= $76K

Taxable Income

Taxable = AGI − Standard Deduction

$76K − $15K

= $61K

2024 standard deduction: $14,600 (single)

Federal Income Tax (bracket)

Tax = Σ (bracket income × bracket rate)

= $8,560 → 10.1% effective

Marginal rate: 22% — but you only pay that on dollars above the bracket threshold.

Combined Effective Rate

Effective Rate = Total Tax ÷ Gross Income

$24,370 ÷ $85K

= 28.7% → $61K take-home

Key insight

Self-employed contractors pay 15.3% SE tax on top of federal income tax — but you can deduct half of it before computing income tax. This is why 1099 rates feel so high vs. W-2.
