Owner-Operator Taxes: What You Actually Need to Know

Taxes are the part of trucking that surprises new owner-operators the most. When you drove for a company, taxes were handled. Now they're your problem — quarterly. Here's what you need to understand.

You pay taxes four times a year now

As a self-employed owner-operator, you're required to make estimated tax payments quarterly:

• •April 15 (for Jan–Mar income)
• •June 15 (for Apr–May income)
• •September 15 (for Jun–Aug income)
• •January 15 (for Sep–Dec income)

Miss these and you'll owe penalties on top of your tax bill in April. A rough rule of thumb: set aside 25–30% of every payment you receive into a separate tax account. Don't touch it.

Self-employment tax hits hard

On top of income tax, you pay self-employment tax — which is Social Security and Medicare that an employer would normally split with you. As a self-employed person, you pay both halves: 15.3% on the first $168,600 of net earnings (2024 threshold).

The good news: you can deduct half of SE tax from your income taxes.

Your biggest deductions

Fuel is your largest deductible expense, but everything that keeps the truck moving and you legal is deductible:

• •Truck payment interest (the interest portion, not the principal)
• •Insurance premiums
• •Maintenance and repairs
• •IFTA taxes paid
• •ELD, phone, and communication tools
• •Permits and licensing fees
• •Scales and weigh stations
• •Lumper fees
• •Association dues and industry publications
• •Accounting and bookkeeping fees

Per diem is a big one many owner-operators underuse. If you're away from home overnight for work, you can deduct a per diem for meals and incidentals. The IRS rate for transportation workers is currently 80% of $69/day ($55.20/day deductible). On 200 nights away from home, that's $11,040 off your taxable income.

Depreciation through Section 179 lets you deduct the full cost of a new or used truck in the year of purchase rather than depreciating it over years. Talk to your accountant about whether this makes sense for your situation.

Get a trucking-specific accountant

This cannot be overstated. A general CPA who does mostly individual returns will miss deductions and may not understand IFTA, operating authority, or the per diem rules for transportation workers. The difference in your tax bill can easily exceed what a specialized accountant costs.

The OOIDA (Owner-Operator Independent Drivers Association) has a referral network of trucking-savvy CPAs. Worth the call.
