The truck itself: your biggest deduction, your biggest decision
How you deduct the truck shapes your tax picture for years. Three paths:
- Depreciation (MACRS): the default, the truck's cost deducted over its recovery period (3 years for tractors), spreading the benefit
- Section 179: expense up to the full purchase price immediately in year one, within limits, powerful in a high-income year, wasted in a low one
- Bonus depreciation: an additional first-year percentage on qualified equipment; the available percentage has been changing year to year, which is exactly why this is a with-your-tax-preparer decision, not a checkbox
The strategy point most drivers miss: front-loading depreciation in a big year and then facing two years of high income with no truck deduction left is a common self-inflicted wound. The right split depends on your income trajectory, deductions are worth the most against your highest bracket. Financed trucks: the interest is deductible too; the principal is not (the depreciation is what deducts the truck's cost).
Operating costs: the everything-else list
- Fuel, typically the largest annual expense; fuel card statements are your documentation
- Maintenance and repairs: parts, labor, oil changes, tires, washes, chrome that keeps the truck working (not the chicken lights, see below)
- Insurance: liability, cargo, physical damage, bobtail/non-trucking liability
- Truck and trailer payments' interest; lease payments if you lease (full payment generally deductible on a true lease)
- Registration, IRP plates, permits, heavy vehicle use tax (2290), IFTA net payments
- ELD subscriptions, load boards, dispatch fees, factoring fees, yes, factoring fees are a deductible cost of doing business, which is one more reason settlements need to be booked gross, not net
- Tolls, scales, lumper fees (get receipts, cash lumpers without paper are the classic lost deduction)
- Phone and internet used for the business (business-use percentage)
- Professional services: bookkeeping, tax prep, legal, including, pleasantly, the fee for preparing this deduction list properly
Per diem: the road deduction drivers underuse
Nights away from your tax home on DOT-regulated work earn a daily meal-and-incidental deduction at the federal transportation-worker rate, no meal receipts required, just proof of the nights (logs do this). For a driver out 250+ nights, per diem is thousands in deductions that many DIY returns undercount by simply not counting nights properly.

The commonly missed list
- Truck supplies: straps, chains, tarps, tools, gloves, cleaning supplies, the CB, the inverter, the fridge
- Sleeper berth costs: bedding, curtains, the bunk heater
- Medical exams required for the job: DOT physicals, drug tests (job-required medical isn't 'personal medical')
- Training and licensing: CDL renewals, endorsements, hazmat fingerprinting, continuing education
- Business-use-of-home, if you genuinely run dispatch/admin from a dedicated space
- Depreciation on the trailer, the APU, and equipment bought separately from the truck
- Self-employed health insurance premiums, an above-the-line deduction outside the business entirely, missed constantly
- Retirement contributions: SEP-IRA or Solo 401(k), arguably the most valuable 'deduction' available to a profitable owner-operator, and the least used
What you can't deduct (stop trying)
- Commuting from home to a fixed terminal or yard, personal, even in the truck
- Everyday clothes (jeans, boots that double as street wear); DOT-required safety gear is fine
- Meals at home, or meals on the road beyond per diem rules
- The radar detector, and fines/tickets of any kind, explicitly non-deductible
- Personal miles and the personal share of mixed-use anything, claim the business percentage, documented
Documentation: the part that makes it real
Every line above survives an exam only as well as its paper: fuel cards and bank statements categorized monthly, receipts photographed at the pump and the parts counter, settlements reconciled gross with deductions itemized, logs supporting per diem nights. This is the actual case for monthly trucking bookkeeping, not tidiness, but converting real expenses into defended deductions at filing time instead of estimates and forfeits. Trucking
Frequently asked questions
I'm a lease-purchase driver, what changes?
Lease payments are generally deductible as you make them (no depreciation, since you don't own yet), and the fleet's settlement deductions, insurance, admin fees, escrow, need itemizing to be captured. Lease-purchase settlements are notoriously messy; booking them gross-vs-net correctly is half the tax battle.
Company driver moonlighting as O/O, can I deduct both?
Only the self-employed side generates business deductions; W-2 driver expenses are not federally deductible under current law. Keep the two worlds' records separate.
Should I do my own trucking return?
The return is where depreciation strategy, per diem, the QBI deduction, and entity questions (that S corp conversation at higher profits) interact, software asks none of it. We prepare returns for our trucking bookkeeping clients from books we already reconciled; the deductions arrive pre-documented. Business Tax Preparation Services
