Every freight broker you work with will ask for your W-9. Without it, they legally cannot pay you. This guide explains exactly what the W-9 is, why it matters, and how to fill it out correctly as an owner-operator or trucking company.
What is a W-9 form?
The W-9 (officially "Request for Taxpayer Identification Number and Certification") is an IRS form that you fill out and give to anyone who pays you for services. It tells the payer: your legal name, your business name (if different), your tax classification, and your Taxpayer Identification Number (TIN) — which is either your Social Security Number (SSN) or your Employer Identification Number (EIN).
Freight brokers use your W-9 to issue you a 1099-NEC at the end of the year — the tax form that reports what they paid you as a contractor. Without your W-9, they cannot legally make payments to you or properly report those payments to the IRS.
Where to get the W-9 form
Download the current W-9 form for free directly from the IRS at irs.gov/forms-pubs/about-form-w-9. Always use the current version — the form is updated periodically. Do not use a W-9 from a third-party website that might be outdated.
How to fill out a W-9 as an owner-operator
Line 1: Name
Enter the name on your tax return. If you file as an individual (sole proprietor), this is your personal legal name. If you file as an LLC or corporation, this is the legal name of the entity as it appears in your formation documents.
Line 2: Business Name / DBA
If your business has a trade name or DBA (Doing Business As) name that is different from Line 1, enter it here. Example: Line 1 might be "John Rodriguez" and Line 2 might be "Rodriguez Trucking LLC." If there's no DBA, leave Line 2 blank.
Line 3: Tax Classification
Check the box that matches your business structure:
- Individual/Sole proprietor or single-member LLC — if you operate as an individual or have a single-member LLC that hasn't elected to be taxed as a corporation
- LLC — if you have a multi-member LLC, enter C, S, or P in the space provided based on your tax election
- C Corporation or S Corporation — if your business is structured as a corporation
Most new owner-operators check "Individual/sole proprietor or single-member LLC." If you're unsure, consult your accountant.
Line 4: Exemptions
Leave blank. This section is for exempt payees (large corporations, government entities). Owner-operators are not exempt payees.
Lines 5-6: Address
Your current business address. This is where the broker will mail your 1099 at year-end.
Part I: Taxpayer Identification Number
This is the most important part. Enter either your Social Security Number (SSN) or Employer Identification Number (EIN) — whichever you use to file your taxes.
- If you have an EIN — use your EIN. Your EIN keeps your SSN private and is recommended for any business owner.
- If you don't have an EIN — use your SSN. You can apply for a free EIN at irs.gov/businesses/small-businesses-self-employed/apply-for-an-employer-identification-number-ein-online
Important: Do not use both. Choose one and use it consistently with all brokers and for your tax filings.
Part II: Certification
Sign and date the form. By signing, you are certifying that the information is correct and that you are a US person for tax purposes.
Pro tip: Get an EIN if you don't have one
Apply for a free EIN at irs.gov. It takes about 10 minutes online and you get your number immediately. Using an EIN instead of your SSN on W-9s protects your Social Security Number from being distributed to every broker you work with.
⚠ Your W-9 is a separate document from your carrier packet
TruckerPacket includes a W-9 information summary in your carrier packet PDF — a quick reference with your EIN and business name. However, the actual IRS W-9 form is a separate document you must download, fill out by hand (or digitally), sign, and attach separately. Do not send just the summary — brokers need the actual signed IRS form.
