An employee’s paycheck usually arrives with income tax already taken out. An independent owner-operator’s settlement generally does not. It may show other deductions, but the income tax and self-employment tax on that money are usually yours to pay, so part of what arrives is already owed, and the bill for it can come long after the freight was delivered. Drivers who have a bad first April often did not earn too little. They spent money that was already owed.
Why is your take-home lower than your settlement statement?
As a company driver, tax came out before you saw the money. As an independent owner-operator you are self-employed, income tax is generally not withheld from your settlements, and paying it is your responsibility, in advance, on a schedule you have to keep without being reminded.
There are two layers. Income tax works the way it always did, on profit rather than on revenue. On top of it sits self-employment tax, which is the layer company drivers never see because an employer was quietly paying half of it. Now you pay both halves.
This is also why gross rate per mile is a misleading way to compare an owner-operator seat with a company seat. The honest comparison is what is left after operating costs and after tax, and working out the first half of that is covered in the earnings guide.
What is self-employment tax, and who pays it?
The IRS sets the self-employment tax rate at 15.3 percent, made up of 12.4 percent for social security and 2.9 percent for Medicare (IRS, self-employment tax). It is charged on your net earnings from self-employment, which means profit after business expenses, not the total the carrier paid you.
Three things follow that catch people out:
- It starts almost immediately. The IRS requires Schedule SE once net earnings from self-employment reach 400 dollars. There is no comfortable band at the bottom.
- It sits on top of income tax, not instead of it. Two separate calculations on the same profit.
- Part of it comes back. The IRS lets you deduct the employer-equivalent portion of your self-employment tax when figuring adjusted gross income. It softens the number; it does not remove it.
Above a threshold that depends on your filing status, an additional 0.9 percent Medicare tax applies to self-employment income. Whether you reach it is one more reason to have a preparer look at the full picture.
Want a settlement you can plan around?
StarBriges pays cargo van owner-operators weekly by direct deposit. Send your MC and van details. We’ll review them within one business day.

Open a second account on the day you start, and move money into it from every settlement before you pay anything else. Not at the end of the month, and not what is left over. Before.
How much to move depends on profit, not gross, because that is what the tax is calculated on. Take what the settlement paid, subtract what that week cost you to run, and set aside a share of what is left. Until you know your cost per mile, keep that share on the high side and adjust it once your records show real numbers. Releasing money you held back is easy. Finding extra money in March is not.
What makes this workable is bookkeeping you actually keep. Every settlement in, every fuel stop, repair, insurance payment and permit out, recorded weekly rather than reconstructed annually. Your tax bill is calculated on profit, and an expense you cannot document is an expense you may not be able to deduct. A driver with a shoebox of receipts and a driver with a spreadsheet can pay different amounts on identical freight.
When do you actually pay?
Not once a year. The IRS expects estimated tax payments from self-employed people who expect to owe 1,000 dollars or more for the year, and it divides the year into four payment periods with their own due dates, published on Form 1040-ES (IRS, estimated taxes).
Miss them and the penalty is not for being short at the end of the year. It is for being late during it. The IRS describes a safe harbor: you generally avoid the penalty if you owe less than 1,000 dollars after withholding and credits, or if you paid at least 90 percent of the current year’s tax or 100 percent of the tax shown on the prior year’s return, whichever is smaller. If your prior-year adjusted gross income was over 150,000 dollars (75,000 if married filing separately), the prior-year figure becomes 110 percent (IRS Publication 505).
For a first-year owner-operator with no prior self-employed return to lean on, that safe harbor is thinner than it looks, which is another argument for holding back too much rather than too little in the first year.
What can you deduct?
The general test is ordinary and necessary for the business. In a van operation that reaches further than most new owners expect:
- Fuel, tolls, parking and scales. The daily spending, and the easiest to lose track of.
- Maintenance, tires and repairs, including the roadside ones you paid cash for.
- Insurance premiums on the commercial policies the business carries.
- Authority, registration, permits and filing fees, including the annual ones that recur quietly.
- Load boards, dispatch fees, factoring fees and bank charges on the business account.
- Phone, data, navigation and any software the operation runs on, to the extent it is business use.
- Straps, blankets, load bars, tools and safety equipment.
- Lodging on the road, and meals, which are treated under their own rules rather than as a straight business expense.
Meals deserve a warning. The general rule limits the deductible share of an unreimbursed business meal, and there is a separate standard meal allowance for people working in the transportation industry, set as a daily figure that the IRS revises from year to year. There is also a distinct rule for individuals subject to the Department of Transportation hours of service limits, and whether that reaches you depends on whether your van counts as a commercial motor vehicle, which turns on its weight rating or actual weight and on running interstate, not on the kind of freight you haul. Do not copy a figure from a forum post. Get the current year’s number and the right rule from a preparer who has road freight clients.
How does the van itself get deducted?
Not all at once as a purchase, and not never. The van is a business asset, and its cost comes back to you over time through depreciation, with provisions that can accelerate a large part of it into the year you put the van into service.
Those provisions carry dollar limits and eligibility conditions that change from tax year to tax year, and they interact with how the van was financed and how much of its use is business use. How you depreciate the van can affect your deductions for several years, so it is worth reviewing with a tax professional against the current year’s rules rather than last year’s advice.
There is a second decision alongside it, between deducting actual vehicle costs and using a mileage method. Which one you can use depends on your situation, and the first year’s decision can limit your options in the years after it. Ask the question before you file, not after.
Do you need an LLC or an S corporation?
You do not need either one to start. You can operate as a sole proprietor with your authority and insurance in your own name. The self-employment tax above applies either way, because a single-member LLC is, by default, taxed the same way as a sole proprietor.
What an entity does give you is separation between business liabilities and personal assets, and a clean line between business and personal money that makes the bookkeeping above much easier to keep honest. The S corporation conversation, which is genuinely about tax, is usually worth having once your profit is consistent and large enough for the extra filing and payroll work to be paid for by what it saves. That is a conversation with an accountant and a profit and loss statement in front of you, not a decision to make in week one.
Everything on this page is general information rather than tax advice, and the numbers that carry a year attached to them move. What does not move is the habit: hold money back from every settlement, keep records weekly, pay quarterly, and ask a professional the two or three questions that are specific to your van. The rest of the owner-operator guides cover the operating side of the same arithmetic. StarBriges pays weekly, so owner-operators who choose to set aside tax money from each settlement can do so on a regular schedule.
