Business expense deductions

expenses + mileage + home office

= $8,100

Expenses: $4,000 + Mileage: 5,000 mi × $0.67/mi = $3,350 + Home office: 150 sq ft × $5 = $750

IRS 2024 standard mileage rate: $0.67/mi; simplified home office: $5/sq ft max 300 sq ft

2

Net SE income

gross gig income − all deductions

= $51,900

$60,000 − $8,100 = $51,900

3

SE tax base

net SE income × 0.9235

= $47,930

IRS rule: SE tax applies to 92.35% of net self-employment income (not 100%)

IRC §1402(a)

4

Self-employment tax

SE base × 15.3% (Social Security 12.4% + Medicare 2.9%)

= $7,333

$47,930 × 15.3% = $7,333. W-2 employees only pay 7.65% — gig workers pay both halves.

IRC §1401

5

Half SE deduction (reduces AGI)

SE tax × 50% = deductible

= $3,667

Self-employed may deduct half of SE tax before federal brackets (IRC §164(f))

IRC §164(f)

6

Adjusted gross income (AGI)

net SE income + other W-2 income − half SE deduction

= $48,233

$51,900 + $0 W-2 − $3,667 half-SE = $48,233

7

Taxable income (after standard deduction)

AGI − standard deduction

= $33,633

$48,233 AGI − $14,600 standard deduction (single) = $33,633

2024 standard deduction: $14,600 single, $29,200 MFJ, $21,900 HoH

8

Federal income tax

2024 marginal brackets applied to taxable income

= $3,804

Highest bracket hit: 12.0% marginal rate

9

State income tax

net SE income × 0.0% (Texas)

= $0

Texas has no state income tax

10

Total annual tax burden

SE tax + federal income tax + state income tax

= $11,137 (18.6% effective rate)

$7,333 SE + $3,804 federal + $0 state = $11,137

11

Quarterly estimated payment

total annual tax ÷ 4

= $2,784 due Apr 15, Jun 17, Sep 15, Jan 15

IRS requires estimated payments if you expect to owe $1,000+ in taxes

IRS Form 1040-ES

12

Net take-home

gross income − expenses − mileage − home office − all taxes

= $40,763 (you keep 81.4%)

Of every $1.00 earned, you keep $0.81 after taxes and deductible expenses
