What sparked the conversation

A new r/tax thread from a driver weighing owner-operator and 1099 options asks whether to hire a pro, file solo, and whether to form an LLC or elect S‑corp status. Top replies stress that trucking taxes are complex, and that the choice of entity should be driven by modeled numbers, not buzzwords—echoing the experience many of you share in the field.

Entity choice: don’t chase labels—run the math

An LLC is a legal shell; by default it’s taxed like a sole proprietorship unless you elect otherwise. An S corporation can reduce exposure to self‑employment tax when profits comfortably support “reasonable compensation” plus distributions, but it also adds payroll, filings, and bookkeeping. The IRS is clear that shareholder‑employees must be paid reasonable wages before taking distributions, so build those costs into your model before you file an election.

Quarterly payments: stay ahead of penalties

If you’re paid on 1099, you’ll generally owe quarterly estimated taxes using Form 1040‑ES. For tax year 2026, the standard due dates are April 15, June 15, September 15, and January 15, 2027. Set calendar reminders and pay electronically to avoid underpayment penalties.

Your biggest 2026 deductions, explained

DOT per diem (M&IE): Transportation workers may use the special meals-and-incidental-expenses per diem instead of actual meal receipts. For travel years beginning October 1, 2025 (covering most of 2026 travel), the IRS set the rate at $80 per day within CONUS and $86 OCONUS. Drivers subject to DOT hours-of-service rules can generally deduct 80% of meals. Keep duty logs and trip records to substantiate days away from tax home.
Fuel, repairs, insurance, permits, and depreciation: Most owner‑operators use the actual‑expense method for tractors and trailers, including depreciation under MACRS and, where appropriate, Section 179 or bonus depreciation. The optimal mix depends on your equipment cost, profit outlook, and state conformity—work with a pro to model cash‑flow and multi‑year impacts.
Mileage rate (for qualifying light vehicles): If you legitimately use a car, pickup, or van that qualifies for the standard mileage method (and you meet IRS restrictions), the 2026 business rate is 72.5¢ per mile. Heavy trucks and tractors are typically handled via actual expenses, but local operations occasionally use mileage for smaller vehicles. Check eligibility rules before you choose.
Self‑employment tax: Net earnings are subject to SE tax (Social Security and Medicare) at 15.3%, with half deductible as an adjustment to income. Plan for this on top of income tax when you set your quarterly payment targets.

A 2026 wrinkle: the end of QBI for many filers

Many independent truckers benefited from the 20% qualified business income (QBI) deduction in prior years. As of May 2026, the IRS notes that the deduction applies to tax years beginning after December 31, 2017, and ending on or before December 31, 2025—meaning 2026 income generally does not qualify absent new legislation. If you counted on QBI in the past, adjust your cash flow and estimates accordingly.

Practical steps owner‑operators can take now

Separate your money: Use a dedicated business bank account and card to make expense tracking and substantiation simple.
Save before you spend: Sweep a fixed percentage of every settlement (many drivers target 25–35% depending on state and deductions) into a tax reserve to cover quarterly payments.
Document days away: For per diem, log departure/return times and overnight status; your ELD and trip sheets are your friends if the IRS asks.
Model S‑corp carefully: Price in payroll service fees, state filings, and your required W‑2 wage. An election can pay off for higher‑profit O/Os, but it’s not one‑size‑fits‑all.
Calendar the big four: Lock in your 1040‑ES dates for 2026 so penalties don’t eat your margin.

Bottom line

The Reddit consensus aligns with best practice in trucking: hire a tax pro who understands the industry, run entity decisions off real numbers, and systematize your per diem, equipment write‑offs, and quarterly payments. With QBI largely off the table for 2026, planning matters more than ever—especially for O/Os scaling up or eyeing an S‑corp.
