Courier and delivery service businesses range from independent Amazon DSP drivers to medical courier services, legal document delivery, and same-day local delivery. The tax picture is vehicle-dominant: fuel, insurance, maintenance, and depreciation are the largest expenses. For gig economy drivers (DoorDash, Uber Eats, Instacart), the standard mileage deduction is often the single most important tax item. For dedicated courier businesses, route density and fleet management drive profitability. This business isn’t a specified service trade or business (SSTB) under IRC 199A.

✓Key takeaway

Courier/delivery tax structure:

SSTB status: NOT an SSTB. Full QBI deduction available at all income levels.

Vehicle deduction (the dominant expense):

Standard mileage (2025): 70 cents per mile
A full-time delivery driver covers 25,000-40,000+ business miles/year
At 30,000 miles: $21,000 standard mileage deduction
OR actual expenses: fuel ($5,000-$10,000/year), maintenance ($2,000-$4,000/year), insurance ($2,000-$4,000/year), depreciation
Standard mileage is usually better for cars and light vehicles
Actual expenses are usually better for vans and cargo vehicles with high depreciation

Business models affect the tax picture:

Independent contractor (gig delivery): Schedule C, all vehicle expenses deductible, no employees
Dedicated courier (medical, legal, same-day): Higher revenue per delivery, route contracts, may have employees
Amazon DSP (Delivery Service Partner): Fleet of vans, employees, high revenue but tight margins
Last-mile delivery (FedEx, USPS contractor): Route-based, requires specific vehicles, predictable revenue

Workers’ comp: low rates for delivery work (2-5% of payroll), making the S-Corp more attractive than in high-risk trades.

S-Corp break-even: approximately $60,000-$70,000 net income (low workers’ comp + low admin costs make the break-even lower than construction trades)

What does the tax picture look like for a courier service?

Hypothetical example

Round numbers. A sole proprietor medical courier service. Revenue: $150,000 (contracts with hospitals, labs, pharmacies). Single filer.

Revenue: $150,000

Deductions:

Vehicle (35,000 miles x $0.70): $24,500
Insurance (commercial auto + GL): $4,000
Phone and GPS: $1,200
Dispatch/routing software: $600
Vehicle maintenance (beyond what standard mileage covers: the standard mileage rate includes depreciation, insurance, and maintenance, so these can’t be deducted separately): $0 (included in standard mileage)
Marketing and contracts: $2,000
Uniforms: $400
Total deductions: $32,700

Net profit: $117,300

As sole proprietorship:

SE tax: $117,300 x 92.35% x 15.3% = $16,564
QBI deduction: $117,300 x 20% = $23,460
Taxable income: $117,300 - $8,282 - $15,000 - $23,460 = $70,558
Income tax: approximately $10,600
Total tax: $27,164

As S-Corp (reasonable salary: $45,000):

FICA on salary: $6,885
Workers’ comp: $45,000 x 3% = $1,350
Distribution: $117,300 - $45,000 - $1,350 = $70,950
QBI: $70,950 x 20% = $14,190
Taxable income: $45,000 + $70,950 - $15,000 - $14,190 = $86,760
Income tax: approximately $13,800
S-Corp admin: $1,500
Total tax + costs: $23,535

Net S-Corp savings: $3,629/year

The low workers’ comp rate (3%) makes the S-Corp clearly beneficial at $117,300 net income. Courier and delivery businesses are among the best candidates for S-Corp election because:

Low workers’ comp rates
No materials inventory (no COGS complexity)
High vehicle deduction reduces net income but not the S-Corp benefit structure
Predictable revenue from contracts

Gig delivery driver comparison: A DoorDash/Uber Eats driver earning $60,000 gross with 25,000 miles:

Standard mileage deduction: $17,500
Net profit: $42,500
SE tax: $6,001
The S-Corp doesn’t make sense at $42,500 net (below the break-even)
Stick with sole proprietorship and maximize the mileage deduction
