How to Calculate Truck Driver Taxes
Owner-operators are self-employed and file Schedule C for business income. The key advantage is the DOT per diem deduction β truckers under DOT hours-of-service rules can deduct 80% of $69 per day ($55.20/day), compared to just 50% for other workers.
The Formula
Per Diem Deduction = Days on Road Γ $69 Γ 80%
Total Deductions = Fuel + Truck Payment + Insurance + Maintenance + Tolls + Per Diem + Other
Net Income = Gross Income β Total Deductions
SE Tax = Net Income Γ 92.35% Γ 15.3% (SS capped at $184,500)
AGI = Net Income β (SE Tax Γ· 2)
Total Tax = Income Tax + SE Tax + State Tax
Total Deductions = Fuel + Truck Payment + Insurance + Maintenance + Tolls + Per Diem + Other
Net Income = Gross Income β Total Deductions
SE Tax = Net Income Γ 92.35% Γ 15.3% (SS capped at $184,500)
AGI = Net Income β (SE Tax Γ· 2)
Total Tax = Income Tax + SE Tax + State Tax

Total deductions: ~$107,800 | Net income: ~$72,200
SE tax: ~$10,207 | Federal tax: ~$6,500 | State: ~$3,600 | Total: ~$20,307
Per diem: 250 Γ $69 Γ 80% = $13,800 | Fuel: $45K | Truck: $24K | Insurance: $12K
Total deductions: ~$107,800 | Net income: ~$72,200

Frequently Asked Questions
What is the DOT per diem rate for truck drivers?
The IRS special per diem rate for Department of Transportation (DOT) transportation workers is $69 per day for 2026 (for continental US travel). Unlike most workers who can only deduct 50% of meal expenses, DOT-regulated drivers can deduct 80% of the per diem amount. This means the effective deduction is $69 Γ 80% = $55.20 per day on the road.
Can owner-operators deduct their truck under Section 179?
Yes. Under Section 179, owner-operators can deduct up to $1,160,000 in the first year for qualifying business equipment including semi-trucks. Additionally, 60% bonus depreciation is available in 2026 for new and used property. This can dramatically reduce your taxable income in the year you purchase the truck, though it may create a large income swing between years.
What is the difference between an owner-operator and a company driver for taxes?
Company (W-2) drivers have taxes withheld and can only deduct unreimbursed expenses via Form 2106 (very limited after 2017 tax reform). Owner-operators (1099 or LLC) file Schedule C and can deduct ALL business expenses directly from income before calculating SE tax and income tax. Owner-operators pay both halves of FICA (15.3% SE tax) but get a 50% SE tax deduction.
Are truck payments deductible for owner-operators?
The loan principal on a truck payment is not deductible, but you can deduct either: (1) actual depreciation and interest, or (2) Section 179/bonus depreciation for the full purchase price in year one. Lease payments are 100% deductible as a business expense. Fuel, maintenance, insurance, tires, and repairs are always deductible regardless of ownership method.
How do owner-operators handle quarterly estimated taxes?
Owner-operators must pay quarterly estimated taxes by April 15, June 16, September 15, and January 15. The safe harbor rule: pay at least 100% of last year's total tax (110% if your prior year AGI exceeded $150,000) to avoid underpayment penalties. Many truckers set aside 25-30% of net income each time they receive payment.
