For transportation & logistics businesses

Yes. Interstate motor carriers require: DOT number (free, federal safety identification), MC number (operating authority, $300 federal fee), BMC-91 / BMC-91X insurance filings, BOC-3 process agent designation, UCR (Unified Carrier Registration), IFTA (International Fuel Tax Agreement) license + decals. Intrastate-only carriers have state-specific requirements. File.Business handles DOT/MC authority + ongoing renewals.

LLC is typical for owner-operators (1-5 trucks). Larger fleets often use S-Corp election for SE tax savings on driver-owner compensation. Asset-heavy carriers often separate truck ownership entity from operating entity for liability protection. File.Business handles multi-entity structures for transportation operators.

Federal minimum (general freight): $750,000 liability. Hazardous materials: $5M. Household goods movers: $300K cargo + $5K cargo/single shipment. Most carriers carry $1M-$2M liability (above federal minimum) + cargo insurance + physical damage + bobtail/non-trucking liability. Coverage filed via BMC-91 with FMCSA.

Interstate truck operators must register for IFTA (International Fuel Tax Agreement) and file quarterly returns reporting miles driven and fuel purchased in each state/province. IFTA reconciles fuel tax between states - you pay fuel tax to the state where the fuel was burned, not just where it was purchased. Quarterly returns required even if no miles driven that quarter.

DOT number (or USDOT number): federal safety identification, required for most commercial vehicles. MC number: operating authority, required for FOR-HIRE interstate transportation of regulated commodities. Most carriers need BOTH. Intrastate-only carriers usually need only DOT. File.Business issues both numbers as part of the MC + DOT bundle.
