Every property broker and freight forwarder operating under U.S. Federal Motor Carrier Safety Administration (FMCSA) authority is required by federal law to maintain a $75,000 surety bond on file with the FMCSA. The bond is filed using FMCSA Form BMC-84. Without an active BMC-84 (or an alternative BMC-85 trust fund), the FMCSA will not issue broker authority, and an existing authority will be revoked within 30 days of a bond lapse.
The bond is one of the most misunderstood pieces of the freight broker business. The good news: for most credit-qualified brokers, getting one approved takes less than a day. The bad news: a single late payment, address change, or lapsed renewal can pull your authority — and reinstating it isn't a phone call, it's starting over.
What the BMC-84 actually guarantees
A surety bond is a three-party promise. You (the broker, called the principal) promise the obligee (the FMCSA, on behalf of the carriers and shippers you do business with) that you'll perform your obligation — in this case, paying the motor carriers who haul your loads. The surety company guarantees that promise. If you fail to pay a carrier, the carrier can file a claim against the bond and the surety pays out, up to the $75,000 limit. The surety then bills you to recover what it paid.
Important: the bond does not protect you. It protects the carriers and shippers you do business with. The premium you pay for the bond is the surety's fee for taking on the risk that you might not pay.
What it actually costs
You don't pay $75,000. You pay an annual premium for the surety's guarantee. The premium depends almost entirely on your personal credit score and, for established brokers, your business financials.
- FICO 750+, 3+ years operating
- $900 – $1,200 / yr
- FICO 700–749, established
- $1,200 – $1,800 / yr
- FICO 650–699
- $1,800 – $2,800 / yr
- FICO 600–649
- $2,800 – $5,000 / yr
- FICO 575–599 (substandard)
- $5,000 – $8,000 / yr
- Below 575 — BMC-85 cash trust instead
- $75,000 cash deposited (no annual premium)
These ranges shift with market conditions and individual surety appetite, but they're a reliable starting point. Your actual rate depends on credit, time in business, claim history, and whether you indemnify with personal assets.
Approval process — what to expect
- Apply with an agent who represents multiple surety markets (not just one). The application asks for the entity name, EIN, contact info, owner(s) with 10%+ ownership, owner SSN(s) for soft credit check, and FMCSA docket number (if you already have one).
- The surety runs a soft credit pull. Standard markets prefer 650+; substandard programs go lower at higher premium.
- If approved, you bind the bond by paying the first year's premium.
- The surety electronically files the BMC-84 with the FMCSA. The filing appears in the FMCSA Licensing & Insurance (L&I) system, usually within 1–3 business days.
- Once the filing posts, FMCSA activates (or maintains) your broker authority.
BMC-85 — the cash alternative
If your credit is low enough that no surety will write a BMC-84 at any rate, federal regulation lets you post $75,000 in cash with an FMCSA-approved financial institution as a trust fund (BMC-85). It satisfies the same requirement. The upside: no credit underwriting. The downside: $75,000 of your working capital is locked up indefinitely.
Most brokers with adequate credit prefer BMC-84 because the annual premium is dramatically cheaper than tying up $75,000 in cash. Brokers with credit issues, or those with deep balance sheets who'd rather not deal with underwriting, sometimes choose BMC-85.
Three mistakes that revoke more authorities than anything else
1. Letting the bond lapse for non-payment
Most surety policies auto-renew. If your payment doesn't go through — expired card, ACH failure, address change that delays the invoice — the surety will cancel the bond and notify the FMCSA. From the FMCSA notice, you have 30 days to reinstate before authority is revoked. After revocation, you reapply from scratch, including a 10-business-day waiting period for new authority.
Fix: set up auto-pay on a card that doesn't expire for at least three years, and confirm the surety has your current address.
2. Multiple authorities, one bond
Each FMCSA broker authority requires its own $75,000 bond. If you operate as ABC Logistics LLC and also as ABC Freight Solutions LLC, each LLC needs its own BMC-84. You cannot share a single bond between two MC numbers.
3. Carrier claims that go unanswered
If a carrier files a claim against your bond, the surety will contact you for a response. If you ignore it, the surety will eventually pay the claim and demand reimbursement from you — and your renewal premium will spike or your bond will be non-renewed entirely. Always respond to claim notices, even if just to say you dispute the claim.
Renewing the bond
BMC-84 bonds are issued for one-year terms and renew annually. A good broker insurance agent will start the renewal conversation 60 days before expiration — re-underwriting your credit and financials, shopping the renewal to multiple surety markets if your profile has improved, and confirming the filing remains active with FMCSA.
Getting started
If you're a new property broker applying for FMCSA authority, you'll need the BMC-84 filed before your authority becomes active. If you're an existing broker shopping renewal, you'll want at least three quotes — premium differences between standard and substandard surety markets can be 3–5×.
