You bought the truck. Now everyone's telling you to "set up an LLC." But should you? And what about an S-corp, or just running as yourself? Here's the plain-English version, minus the legal jargon.

This is education, not legal or tax advice. Talk to a CPA who knows trucking before you file anything.

The three ways to structure one truck

Sole proprietor

This is the default. If you do nothing, you're a sole proprietor. Your business and your personal finances are legally the same thing. Simple to start, cheap, and easy at tax time.

The downside: no liability separation. If your business is sued and loses, your personal assets can be on the line.

LLC (Limited Liability Company)

An LLC creates a legal wall between your business and your personal stuff. If the business gets sued, your house and personal savings are generally protected (assuming you keep the finances separate and follow the rules).

By default, a single-member LLC is taxed exactly like a sole proprietor. No extra tax forms, no double taxation. You get the liability protection without changing how you file. That's why the LLC is the popular middle ground for one-truck operators.

S-corp

An S-corp isn't a separate business type. It's a tax election you can make on top of an LLC. The pitch: you pay yourself a "reasonable salary" and take the rest as distributions, which can lower your self-employment tax.

The catch: S-corps mean payroll, more paperwork, and higher accounting bills. The tax savings usually only outrun those costs once your net profit is solidly high. A CPA can run your numbers and tell you if you're there yet.

What an EIN is for

An EIN (Employer Identification Number) is a tax ID for your business, like a Social Security number for your company. It's free from the IRS.

You'll want one to:

  • Open a business bank account
  • Keep your SSN off paperwork
  • Run payroll if you go the S-corp route

You can get an EIN as a sole proprietor too. It doesn't require an LLC.

When structure actually matters (and when it doesn't)

Here's the honest part. Your business structure affects liability and taxes. It does not decide whether you can get good freight or how you run day to day.

A big point of confusion: business structure is separate from operating authority. Whether you're a sole prop or an LLC, you still need a legal way to haul freight. Some owner-operators chase their own DOT/MC authority. Others lease on to an established carrier and run under that carrier's authority instead.

That's how ARI works. ARI is a motor carrier, not a broker. When you lease on, you run under ARI's DOT/MC authority, so you don't need your own. Your LLC or sole prop still exists for tax and liability purposes, but the authority, compliance, and billing side is handled. Note: with ARI you run under ARI's authority; you can't run your own authority through ARI.

That setup keeps the business decision simple. Pick a structure that fits your tax and liability situation, then focus on running loads instead of managing your own MC number, insurance filings, and IFTA paperwork.

A practical starting point

  • Talk to a CPA about LLC vs. S-corp based on your expected profit.
  • Get an EIN (free) and a separate business bank account.
  • Keep business and personal money strictly separate.
  • Decide how you'll operate: your own authority, or leased on under a carrier's.

If you'd rather skip the authority-and-compliance headache and just haul, leasing on is the cleaner path. ARI keeps that side straightforward with a true 82% revenue share, zero escrow, and same-day pay when you deliver on time.
