How owner-operator taxes work

If you run under your own authority or lease onto a carrier as a 1099 contractor, nothing is withheld from your settlements. You pay 15.3% self-employment tax on net profit (Social Security portion capped at $184,500 in 2026) plus federal income tax at your bracket — and the IRS expects it in quarterly estimated payments. Company drivers on a W-2 don't use this calculator; their taxes come out of payroll.

The trucker per diem: don't leave it on the table

Drivers subject to DOT hours-of-service rules can claim a per diem of $80 per night away from home (the special transportation-industry rate), deductible at 80% — that's $64 of deduction per night, no meal receipts needed. A driver out 250 nights a year deducts $16,000 on top of actual operating costs. Heavy trucks can't use the cents-per-mile rate, so everything else runs on actual expenses: fuel, insurance, repairs and tires, truck/trailer depreciation or lease payments, permits and plates, ELD subscriptions, load-board fees, factoring fees, and business use of your phone.

Also remember Form 2290 heavy vehicle use tax (up to $550/truck/year, deductible) and that fuel purchases already include IFTA fuel taxes you reconcile quarterly — sloppy IFTA records cost real money at audit time.

Frequently asked questions

How much tax does an owner-operator pay?

Typically 20–30% of net profit in federal tax once self-employment tax and income tax are combined. On $180,000 gross with $95,000 of expenses and full per diem, the federal bill usually lands around $14,000–$18,000.

What is the trucker per diem rate for 2026?

$80 per full day away from home for transportation workers, deductible at 80% ($64/day). Partial travel days claim 75% of the rate. You must actually be away overnight under DOT rules.

Can truckers use the standard mileage deduction?

No — semis and heavy trucks are excluded from the cents-per-mile method. Owner-operators deduct actual costs: fuel, repairs, insurance, depreciation, lease payments, and so on.

Should an owner-operator form an LLC or S-corp?

An LLC adds liability protection with no tax change. Once profit consistently clears roughly $60,000–$80,000, an S-corp election can cut self-employment tax meaningfully — run it through our S-corp calculator.

Do I pay quarterly taxes as a trucker?

Yes — if you'll owe $1,000+ for the year. Due dates for 2026: April 15, June 15, September 15, and January 15, 2027.
