Using a Car for Business: New Rules under TCJA (2024)

Many of the tax provisions under tax reform were favorable to small business owners including those relating to using a car for business. Here’s what you need to know.

  1. Section 179 Expense Deduction

If you buy a new car in 2018, and use it more 50 percent for business use, you can take advantage of the Section 179 expense deduction when you file your 2018 tax return. Under Section 179 you can immediately deduct (rather than depreciating) the cost of certain property in the year it is placed in service. In 2018, the Section 179 expense deduction increases to a maximum deduction of $1 million, if you have no more than $2.5 million of qualifying equipment placed in service during the year. It is indexed to inflation for tax years after 2018.

For sport utility vehicles (defined as four-wheeled passenger automobiles between 6,000 and 14,000 pounds), however, the maximum deduction is $25,000 (also indexed for inflation). Certain exceptions may apply, however such as a seating capacity of more than nine persons behind the driver’s seat. Vehicles weighing more than 14,000 pounds are typically considered “work vehicles” and would not be used for personal reasons. As such, there is no expense deduction limit.

  1. Luxury Auto Depreciation Allowance

For luxury passenger automobiles placed in service after 2017, the cap on allowable depreciation increases to a maximum of $10,000. The cap increases to $16,000 for the second year, then decreases to $9,600 for the third year and $5,760 for the fourth year and for years beyond. These dollar amounts will be indexed for inflation in the future. Deductions are based on a percentage of business use, i.e. a business owner whose business use of the vehicle is 100% can take a larger deduction than one whose business use of a car is only 50%.

  1. Additional First-Year Bonus Depreciation for Passenger Vehicles

For passenger autos eligible for the additional bonus first-year depreciation, the maximum first-year depreciation allowance remains at $8,000. It applies to new and used (“new to you”) vehicles acquired and placed in service after September 27, 2017, and remains in effect for tax years through December 31, 2022. When combined with the increased cap on the depreciation allowance above, the deduction can amount to as much as $18,000.

  1. 100 Percent First-Year Bonus Depreciation for Heavy Vehicles

For tax purposes, pickup trucks, vans, and SUVs whose gross vehicle weight rating (GVWR) is more than 6,000 pounds are treated as transportation equipment instead of passenger vehicles. Heavy vehicles (new or used) placed into service after September 27, 2017, and before January 1, 2023, qualify for a 100% first-year bonus depreciation deduction as well, if business-related use exceeds 50%. These deductions are based on percentage of business use, and vehicles used less than 50% for business are required to depreciate the vehicle cost over a period of six years.

  1. Deductions Eliminated for Unreimbursed Expenses for Business Use of a Car

Under tax reform, miscellaneous itemized expenses were repealed. As such, starting in 2018, if you are an employee who is required to use your own vehicle for business-related use and are not reimbursed for these expenses by your employer, you are no longer able to claim a deduction for unreimbursed expenses for business use of a car on your tax return.
