What's different here
- Owner-operators are the classic line-1 case. A driver with an LLC, an EIN from the bank, and a personal SSN on the CDL will give you whichever number is handy. The W-9 has to carry the pair the IRS recognizes (see the W-9 name guide), and the volume means the mismatch rate is high unless onboarding forces the question.
- Carrier authority is a separate check. A carrier needs active FMCSA operating authority (MC/USDOT), insurance on file (BMC-91/91X), and no out-of-service order. None of that is in IRS records. A TIN match plus an authority check plus an insurance check is the minimum before the first load, and authority can lapse mid-year.
- Double-brokering and identity fraud are the sector's specific exposure: a fraudster presents a real carrier's MC number with a different TIN and bank account. The defense is verifying that the legal name on the W-9, the name on the FMCSA record, and the name on the insurance certificate all match, and paying only to the verified entity.
- Factoring companies complicate reporting: when a carrier factors its receivables, you pay the factor but the 1099-NEC still goes to the carrier that performed the service, with the carrier's TIN. Notice-of-assignment records need to preserve the underlying payee.
- Fuel advances, detention, accessorials are all part of the reportable amount to the carrier; reimbursed tolls and scale fees under an accountable arrangement are not.
- Foreign carriers (Canadian and Mexican cross-border) document with a W-8BEN-E and are outside 1099 reporting, but the authority and insurance checks still apply.
An onboarding sequence that holds up
- Collect the W-9 (or W-8BEN-E) and verify the name/TIN pair against IRS records before carrier setup; ask the SSN-or-EIN question explicitly.
- Verify FMCSA authority status, insurance filings and out-of-service status; record the date and re-check on a schedule (monthly for active carriers) because authority lapses.
- Match the legal name across the W-9, FMCSA and insurance records before the first payment; a mismatch is a fraud signal before it's a tax problem.
- Screen the carrier and principals against OFAC; sanctioned parties appear in freight more than most sectors expect.
- For factored carriers, record the assignment and keep the carrier's TIN as the 1099 payee.
