LLC, EIN, and State Business Licensing

Before you file anything with the FMCSA, you need a legal business entity, a tax ID from the IRS, a business bank account, and state permission to operate. This page walks through each step.

Sole proprietorship vs. LLC: the real trade-off

Sole proprietorship is the simplest route. You are your business. No paperwork. No cost. You file taxes as an individual using your Social Security number, and you can start operating immediately.

The catch: you are personally liable. If the business is sued, or if a factoring company or broker puts a lien on you, your personal home, car, and bank account are at risk. For many new owner-operators, this risk is not worth the $0 startup cost.

LLC (Limited Liability Company) costs money and paperwork upfront—typically $50–$500 depending on your state—but it creates a legal barrier between your personal assets and your business. If the LLC is sued or owes money, the creditor can pursue the LLC, not your house. This is the structure most small carriers choose.

The decision: If you’re hauling for other people (broker loads, factoring), an LLC is strongly recommended. If you own one truck and are just running your own small operation with minimal debt, a sole proprietorship is simpler. But most new carriers form an LLC to protect themselves.

Getting an EIN (Employer Identification Number)

An EIN is your business’s tax ID. The IRS assigns them for free.

You need an EIN even if you’re a single-member LLC with no employees. Most banks will not open a business account without one, and you’ll need it to file business taxes and hire any contractors.

How to get one:

Go to IRS.gov and search for “Apply for an EIN.”
You can apply online for free and get your EIN immediately (literally the same day).
You’ll need basic information: your name, business address, business structure, and Social Security number.
The IRS will mail you an official EIN letter, but you can use the number right away to open a bank account.

This step takes 15 minutes online. Do not use a tax preparer or payroll service unless you have other reasons to—you don’t need to pay for something free.

Opening a business bank account

Once you have an EIN, open a separate business bank account. This sounds obvious, but it’s critical.

Commingling business and personal money does two things:

Practically: Your bookkeeping becomes a mess, making taxes and insurance renewals harder.
Legally: It can undermine the liability protection your LLC is supposed to provide. Courts have pierced the corporate veil when business and personal finances were completely mixed.

What you’ll need to open an account:

Your EIN (which the IRS will email or mail to you)
Photo ID
Social Security number
Proof of your business address (utility bill, lease agreement, or mailbox receipt)

Shop around. Different banks have different requirements and fee structures. Some have no monthly fee for small business accounts, while others charge $10–$15/month. Online banks (like Mercury or Brex) often have lower fees than traditional brick-and-mortar banks.

Keep business and personal accounts completely separate. Don’t use your personal card for business expenses. Don’t transfer money back and forth casually. Your bookkeeper (or you, if you’re self-bookkeeping) will thank you, and your accountant will definitely thank you.

Registering with your state

State business licensing requirements vary. Some states require a general “business license” or “business registration.” Others require specific licenses depending on the industry. Some let you register online in minutes. Others require paperwork mailed to your county clerk.

You need to check your specific state. The outline is intentionally not giving you a universal rule because there isn’t one.

Where to start:

Go to your state’s Secretary of State website (Google “[Your State] Secretary of State”).
Look for “business license,” “business registration,” “DBA” (Doing Business As), or “sole proprietorship registration.”
If your state’s site is unclear, contact your county clerk’s office.

Some states require you to file with both the state and your county. Some states have an annual renewal fee. Some have none. You must check your state. If you operate without the required license, you could face penalties or have trouble renewing insurance later.

The sequence, spelled out

Do it in this order:

Choose sole proprietorship or LLC. If LLC, file formation documents with your state (usually online, through your Secretary of State website). Cost: $50–$500 depending on state.
Apply for EIN online. Takes 15 minutes, free. You get the number the same day.
Open a business bank account using your EIN. Takes a few days to a week.
Register with your state as an operating business. Requirements vary; check your state’s Secretary of State site.

Once all four are done, you have a legal business with tax ID, a bank account, and state permission to operate. You’re ready for the Authority phase.

Next steps

With these paperwork steps complete, you can move to the FMCSA side of starting: USDOT number, MC number, BOC-3 form, insurance, and UCR. See USDOT, MC numbers, and authority for that process.

You should also understand the realistic costs before you commit: truck prices, insurance premiums, and initial authority fees. See Business plan and startup costs.
