Tax Home.
IRS-defined principal place of business; for truckers, typically the home base or domicile where the driver lives between trips.
What it is
Tax home is the IRS-defined principal place of business. For truckers, it is generally the city where the driver lives, has family ties, and maintains a permanent residence. Per diem deductions require being "away from tax home" overnight on business — so establishing a clear tax home is a prerequisite for the deduction. Truck drivers who have no fixed home and effectively live in the truck are considered "itinerant" under IRS rules and cannot claim per diem or unreimbursed travel expenses.
Tax home is different from legal domicile (the state of residence for state-tax purposes), though they often align. Establishing a clear tax home requires a permanent residence, a regular return pattern to that residence, and family or financial ties to one location. Documentation includes utility bills, lease or mortgage, vehicle registration, voter registration, driver's license, and ties to local financial accounts.
Why it matters for trucking finance
Drivers without a clear tax home lose per diem deductions worth $13K+ per year — the single largest avoidable tax leakage for an itinerant operator. An itinerant driver also can't deduct other work-related travel expenses, compounding the loss. For new owner-operators, establishing and documenting tax home is one of the most impactful tax decisions in the first year of business. State of tax home affects state income tax exposure — some operators relocate to tax-favorable states (TX, FL, TN, NV — no state income tax) when establishing their owner-op career, and the savings can run $3K–$8K per year on top of the federal per diem deduction.
