Most car purchases are not tax deductible, but business use and certain donations may be

A car you buy for personal use—commuting to work, running errands, taking vacations—cannot be deducted from your taxes. The IRS does not allow you to write off the purchase price of a personal vehicle, even if you use it occasionally for work.

However, if you use a car primarily for business purposes, you may be able to deduct mileage or actual expenses. If you donate a car to a may have access to charity, you may also deduct its fair market value. The rules differ depending on how and why you own the vehicle, so understanding which category applies to you matters.

Key Takeaways

  • Personal vehicles cannot be deducted, even if you drive them to a job or use them for occasional work tasks.
  • If you use a car for business—such as running a delivery service or visiting client sites as part of your work—you can deduct either the standard mileage rate or your actual expenses, but not the purchase price itself.
  • Donating a car to a may have access to charity may allow you to deduct its fair market value, but you must have a written acknowledgment from the charity.
  • Commuting to a regular job is never deductible, even if your employer requires you to use your own vehicle.

Business use: the mileage deduction and actual expense method

If you own a car and use it for business purposes, you have two ways to deduct the cost: the standard mileage rate or the actual expense method. You cannot deduct the purchase price itself under either approach, but you can deduct the cost of operating the vehicle.

The standard mileage rate is a per-mile deduction set by the IRS each year. For 2024, the rate is 67 cents per business mile. You multiply the number of business miles you drove by this rate to get your deduction. This method is simpler because you only need to track mileage, not receipts for gas, maintenance, or repairs.

The actual expense method lets you deduct a percentage of all your car costs—gas, oil changes, insurance, registration, depreciation, and repairs—based on the percentage of miles you drove for business. If you drove 12,000 business miles out of 20,000 total miles, you can deduct 60 percent of those expenses. This method requires detailed record-keeping but may yield a larger deduction if your car is expensive to operate.

You must choose one method in the year you first use the car for business and can switch methods in later years, though switching has restrictions. Keep a mileage log showing the date, destination, business purpose, and miles driven for each trip.

Commuting is never deductible

Driving to and from your regular job is considered commuting, and the IRS does not allow you to deduct commuting expenses under any circumstance. This is true even if you drive a long distance, even if your employer requires you to use your own car, and even if you perform work tasks during the drive.

The distinction between commuting and business use is whether the trip is to your primary workplace. If you work at an office five days a week and drive there each morning, that is commuting. If you leave your home to visit a client site, a job site, or a second location as part of your work, that is business use and may be deductible.

If you work from home and drive to a client meeting or a temporary work location, those miles may be deductible. If you work from home and drive to a coworking space that serves as your office, that is commuting and not deductible.

Car donations to charity

When you donate a car to a may have access to charity, you may deduct its fair market value. Fair market value is what a willing buyer would pay a willing seller for the car, not the price you paid or what you owe on a loan.

The charity must be recognized by the IRS as a may have access to organization—typically a nonprofit with 501(c)(3) status. You can search the IRS Tax Exempt Organization Search tool online to confirm a charity's status before donating.

You must obtain a written acknowledgment from the charity stating the vehicle's identification number, the date of the donation, and a description of the vehicle. If the car is worth more than $500, you must also file Form 8283 with your tax return. If it is worth more than $5,000, you need a may have access to appraisal and Form 8283 Section B completed by the appraiser.

The charity does not have to sell the car for you to claim the deduction. Even if they keep it for their own use, you can deduct the fair market value. However, if the charity sells the car, they must report the sale price to the IRS, and your deduction is limited to the sale price if it is lower than the fair market value you claimed.

Self-employed and business owners

If you are self-employed or own a business, the rules are the same: you cannot deduct the purchase price of a vehicle, but you can deduct the cost of operating it for business purposes. You must still track business mileage and choose between the standard mileage rate and actual expenses.

Some business owners purchase vehicles and depreciate them over several years, which is different from a mileage deduction. Depreciation allows you to deduct a portion of the vehicle's cost each year as it loses value. This approach requires more complex record-keeping and may be better suited to vehicles used exclusively for business. Consult a tax professional to determine whether depreciation or mileage deductions make sense for your situation.

Keeping records for business vehicle deductions

The IRS requires contemporaneous written evidence of business mileage. A mileage log should include the date, starting location, ending location, business purpose, and miles driven. You do not need to log every single trip if you keep a summary, but the IRS expects the log to be created at or near the time of the trip, not reconstructed months later from memory.

If you use the actual expense method, keep receipts for gas, maintenance, repairs, insurance, registration, and loan interest. Photograph or scan these receipts and store them with your tax records for at least three years.

Many drivers use mileage-tracking apps or a straightforward spreadsheet to log trips. Some apps sync with your phone's location data to help you remember trips. Others require manual entry. Either way, the log must be in writing and available if the IRS asks to see it.

Frequently Asked Questions

Can I deduct the cost of a car I bought for work?

No, you cannot deduct the purchase price of any car, even if you use it entirely for work. You can only deduct the cost of operating it—gas, maintenance, insurance—using either the standard mileage rate or actual expenses. The purchase price itself is not deductible.

What if I use my car for both personal and business driving?

You can only deduct the business portion. If you drove 8,000 business miles and 12,000 personal miles in a year, you can deduct the business percentage of your expenses. Keep a mileage log to prove the split between business and personal use.

Is a car donation deductible if the charity sells it?

Yes, but your deduction is limited to the sale price if it is lower than the fair market value you claimed. If you deducted $8,000 but the charity sold the car for $5,000, your actual deduction is $5,000. The charity reports the sale price to the IRS.

Can I deduct my car payment or loan interest?

Car loan interest is not deductible for personal vehicles. If you use a car for business and use the actual expense method, you can deduct the interest portion of your loan payments as part of your vehicle expenses. The standard mileage rate already accounts for depreciation and financing costs, so you cannot use both.

Do I need to report business mileage on my tax return?

You report the deduction amount on your tax return, not the mileage itself. If you use Schedule C (for self-employed income), you enter the vehicle expenses or mileage deduction there. The IRS may ask to see your mileage log if they audit your return, so keep it for at least three years.
