Can a CRE broker write off a vehicle purchase?
Yes ā to the extent you actually use the vehicle for business. Property tours, site visits, and client meetings are legitimate business miles, and brokers typically deduct vehicle costs through either the standard mileage rate or actual expenses with depreciation. For a heavier SUV or truck used mostly for business, first-year depreciation can be substantial. But the deduction is limited to your business-use percentage, and the answer to "should I buy the vehicle for the write-off" is almost always a modeling question, not a yes.
Two ways to deduct a vehicle
The IRS gives you two methods, and you generally pick one per vehicle:
- Standard mileage. A flat per-mile rate (roughly 70 cents per business mile in recent years ā the IRS updates it annually) that bundles gas, insurance, maintenance, and depreciation into one number. Simple, and often the better answer for high-mileage, lower-cost vehicles.
- Actual expenses. You deduct the business-use share of real costs ā fuel, insurance, repairs, registration ā plus depreciation on the purchase price. This is where the large first-year deductions live, and it usually wins for newer, more expensive vehicles.
Once you use actual expenses with accelerated depreciation on a vehicle, you generally can't switch that vehicle back to the standard mileage rate. The choice matters up front.
Why the heavy-SUV rule gets so much attention
Passenger cars face annual "luxury auto" depreciation caps that stretch the write-off over many years. Vehicles with a gross vehicle weight rating above 6,000 pounds ā which covers many full-size SUVs and trucks brokers actually drive ā escape those caps. For those vehicles, Section 179 expensing (subject to a specific SUV dollar cap, roughly low-$30,000s and inflation-adjusted each year) plus bonus depreciation can put a large share of the purchase price into year one.
The part everyone skips: business-use percentage
Every depreciation figure above gets multiplied by your business-use percentage. Drive the vehicle 70% for business, and 70% of the depreciation is deductible ā period. Two other rules follow from this:
- Below 50% business use, the aggressive options disappear. Section 179 and bonus depreciation generally require more-than-50% business use, and falling below that line in a later year can trigger recapture ā previously claimed depreciation added back to income.
- A mileage log is not optional. Business-use percentage is established by contemporaneous records. "I drive a lot for work" does not survive an audit; a mileage app does.
Illustrative only. The actual result depends on the year's 179 SUV cap, bonus depreciation percentage, your marginal bracket, QBI interactions, and state conformity ā several states don't follow federal bonus depreciation. A big deduction now also means little or no depreciation later, and a lower basis when you sell.
The trap: buying a vehicle "for the write-off"
A deduction reduces your taxes by your marginal rate ā it never pays for the vehicle. Spending $80,000 to save roughly $20,000 only makes sense if you needed the vehicle anyway. There's also the exit: when you sell or trade a heavily depreciated vehicle, the gain (often most of the sale price, since your basis is near zero) comes back as income. The first-year deduction is partly a timing benefit, not free money.
Get the actual number before you buy
The decision has enough moving parts ā mileage vs. actual, 179 caps, bonus percentage, business-use share, your bracket, your state, the resale exit ā that gut feel gets it wrong in both directions. Our Vehicle Purchase Analysis models all four scenarios on your actual numbers and shows you the year-by-year after-tax cost of the specific vehicle you're considering, before you sign anything.
