Owner-Operator Tax Deductions & Expenses

Your biggest expense and your biggest deduction. Every gallon of diesel you buy for business use is deductible. A typical solo owner-operator spends $50,000–$80,000/year on fuel. Keep every receipt — or better, use a fuel card that logs purchases automatically.

DEF (Diesel Exhaust Fluid) and reefer fuel are also deductible separately. If you use a major fleet fuel card (EFS, Comdata, and similar), your purchases can be categorized by state automatically — which also feeds your IFTA calculations.

If you own your truck, you can deduct the cost through depreciation (typically over 3-5 years using MACRS). If you lease, your monthly lease payment is fully deductible as a business expense.

Section 179 allows you to deduct the full purchase price of a qualifying truck in the year you buy it, up to the current limit. For a $150,000 truck, that's a massive deduction in year one. Talk to your CPA about whether Section 179 or standard depreciation is better for your situation.

All business insurance premiums are deductible:

• Liability insurance — $8,000–$12,000/year (higher for new authority)
• Cargo insurance — $400–$1,200/year
• Physical damage / comprehensive & collision — $2,000–$5,000/year
• Bobtail / non-trucking liability — $300–$600/year
• Occupational accident insurance — $100–$200/month
• Workers' comp — if required in your state

Oil changes, tires ($400-$600 each, 18 on a semi), brakes, engine repairs, APU maintenance, trailer repairs — all deductible. A well-maintained truck averages $0.12-$0.18 per mile in maintenance costs.

Routine maintenance is expensed in the year it's paid. Major repairs or overhauls (engine rebuild at $15,000-$25,000) may need to be capitalized and depreciated — check with your CPA.

The DOT per diem rate allows truck drivers to deduct a set amount per day for meals when away from their tax home overnight. The current rate is 80% of the federal meals rate — which works out to roughly $59/day (80% of the $74 M&IE rate for most locations).

For an OTR driver away 300 days/year, that's approximately $17,700 in deductions. This is one of the largest and most commonly missed deductions for owner-operators.

The IRS pays attention to certain patterns:

• Claiming 100% business use on a truck you also drive personally — be honest about the split
• No receipts for large deductions — especially fuel and maintenance
• Per diem claimed for days you were home — only claim days you were away from your tax home overnight
• Mixing personal and business expenses — use a separate business bank account and fuel card

You can only deduct what you can document. The IRS requires records for every business expense. Come tax time, you need categorized totals, not a shoebox of receipts.
