Owner-operators have more deductible expenses than most small business owners realize. Almost everything you spend to keep your truck running and yourself on the road qualifies as a business expense.

Truck payments or lease payments are deductible. If you own the truck outright, you can depreciate it over several years or use Section 179 to deduct the full purchase price in one year. Trailers, ELD devices, GPS units, and CB radios all count too. Keep records of purchase dates and amounts because how you deduct equipment depends on when you bought it.

Fuel is usually your biggest expense and it’s fully deductible. Save receipts or use a fuel card that generates reports. DEF fluid, oil, and other fluids count too. The IRS expects documentation for fuel expenses, so relying on memory or estimates creates problems during an audit.

Maintenance and repairs are deductible when they happen. Tires, brake work, oil changes, engine repairs, truck washes. If something breaks and you fix it, that’s a deduction. Upgrades that improve the truck get treated differently and may need to be depreciated rather than expensed immediately.

Per diem is a significant deduction unique to transportation businesses. Instead of tracking every meal receipt, you can claim a daily rate for meals while away from home overnight. The DOT rate is currently $69 per day for domestic travel. You can deduct 80% of that amount. Track your nights away from your tax home and multiply by the rate. This alone can add up to thousands in deductions annually.

Insurance premiums are fully deductible. Commercial truck insurance, cargo insurance, bobtail insurance, and occupational accident coverage all count. Health insurance premiums for yourself and your family are deductible too if you’re self-employed and not eligible for coverage through a spouse’s employer.

Tolls and scale fees are deductible. Keep receipts or use a transponder that generates statements. Parking fees at truck stops count too. Lumper fees you pay out of pocket are deductible as long as you document them.

Licensing and regulatory fees add up and they’re all deductible. CDL renewal, MC authority fees, IFTA quarterly taxes, IRP registration, UCR registration, drug testing, and DOT physicals. Association dues for OOIDA or other trucking organizations count as well.

Phone and internet expenses are deductible for the business portion. If you use one phone for business and personal, estimate the business percentage and deduct that amount. Load board subscriptions, dispatch service fees, and factoring fees are fully deductible business expenses.

Home office deduction applies if you have a dedicated space at your tax home where you handle administrative work. The simplified method gives you $5 per square foot up to 300 square feet. Not every owner-operator has a home office, but if you do, claim it.

Professional services including accounting, bookkeeping, and legal fees are deductible. Working with a bookkeeping service in Macomb that understands owner-operator expenses helps you capture deductions throughout the year instead of scrambling at tax time.

What you cannot deduct includes personal meals when you’re home, commuting from home to your truck if it’s parked elsewhere, traffic tickets and fines, and the personal portion of any mixed-use expense.

The owner-operators who pay the most in taxes are usually the ones who don’t track expenses throughout the year. Fuel receipts get lost, per diem days aren’t logged, and small expenses that add up to real money never make it onto the tax return. Good recordkeeping is the difference between paying what you owe and overpaying because you can’t prove what you spent.
