Most car purchases are not tax deductible, but some business and medical uses are

If you bought a car for personal use — commuting to a job, running errands, taking vacations — you cannot deduct the purchase price on your taxes. The IRS does not allow deductions for personal vehicles, even if you use them occasionally for work.

However, if you use a car primarily for business purposes, medical treatment, or charitable work, you may be able to deduct part or all of the cost. The key is understanding which uses may have access to and how to document them. The rules differ depending on whether you own the car outright, finance it, or lease it.

Key Takeaways

  • Personal car purchases and commuting costs are never deductible, even if you work from home part-time or drive to a job site.
  • Business vehicles can be deducted using either the standard mileage rate (a per-mile deduction set by the IRS each year) or actual expense method (tracking fuel, maintenance, insurance, and depreciation).
  • Medical and charitable driving may be deductible at a lower rate than business mileage, but only if you track dates, destinations, and miles driven.
  • You must choose your deduction method in the year you first use the vehicle for business, and switching methods later requires IRS permission.
  • Leased vehicles follow the same deduction rules as owned vehicles, but you cannot deduct lease payments for personal use.

Business vehicle deductions: the two methods

If you use a car for business — whether you are self-employed, a contractor, or an employee with unreimbursed work expenses — you can deduct the cost using one of two approaches. The standard mileage rate is simpler: you multiply the number of business miles driven by the IRS rate for that year. For 2024, the rate is 67 cents per mile for business driving (this rate changes annually). You only need to track miles and dates; you do not deduct the actual purchase price.

The actual expense method requires more record-keeping but may yield a larger deduction if your vehicle is expensive to operate. You track and deduct the actual costs: purchase price (depreciated over several years), fuel, maintenance, repairs, insurance, registration, and loan interest. You calculate what percentage of your annual miles are business miles, then deduct that same percentage of your total expenses. For example, if 60% of your driving is business-related, you deduct 60% of your insurance, fuel, and other costs.

You must choose one method in the year you first use the vehicle for business and stick with it for the life of the vehicle, or request permission from the IRS to switch. Most people find the standard mileage rate easier unless they drive a luxury vehicle or have very high maintenance costs.

Medical and charitable driving

Driving to medical appointments or to volunteer for a may have access to charity may also be deductible, but at a lower rate than business mileage. For 2024, the medical mileage rate is 21 cents per mile, and the charitable rate is 14 cents per mile. These rates also change annually.

To claim these deductions, you must track the date, destination, miles driven, and the purpose of each trip. A general note like "doctor visits in January" is not enough; the IRS wants to see that you drove to a specific appointment on a specific date. Keep a mileage log in your car or use a mileage-tracking app that records GPS data.

Medical driving includes trips to your own medical appointments, to pick up prescriptions, or to drive a dependent to their medical care. Charitable driving must be for a may have access to organization — typically a 501(c)(3) nonprofit — and you must be driving on behalf of the organization, not just attending an event there.

What you cannot deduct

Commuting to a regular job is never deductible, even if you drive a long distance or work in multiple locations. The IRS considers commuting a personal expense. If you work from home and occasionally drive to a client meeting, only those specific trips count as business miles; your regular commute does not.

Parking fees and tolls related to commuting are also not deductible. However, parking and tolls for business trips, medical appointments, or charitable work are deductible as part of your mileage or actual expenses.

If you use a vehicle for both personal and business purposes, you can only deduct the business portion. If you drive 10,000 miles per year and 4,000 of those are for business, you deduct only 40% of your expenses or mileage.

Documentation you need to keep

The IRS requires contemporaneous written evidence of your mileage — meaning you should record it at or near the time you drive, not months later from memory. A mileage log does not need to be fancy; a straightforward notebook in your car works, or you can use an app like MileIQ, Stride Health, or Everlance that records trips automatically.

Your log should include the date, starting and ending odometer readings (or total miles), destination, business purpose, and whether the trip was business, medical, or charitable. If you use the actual expense method, also keep receipts for fuel, maintenance, insurance, and registration.

If you are audited, the IRS will ask to see this documentation. Without it, you cannot claim the deduction. A general statement that you drove for business is not enough.

Leased vehicles and financed vehicles

If you lease a car for business use, you can deduct the lease payments using the same methods as an owned vehicle. You can either use the standard mileage rate (which implicitly accounts for lease costs) or deduct your actual lease payments as part of the actual expense method. You cannot use both methods simultaneously.

If you financed a car purchase, you can deduct the business portion of the vehicle cost through depreciation, but you cannot deduct the loan interest separately if you are using the standard mileage rate. The standard rate already factors in depreciation. If you use the actual expense method, you can deduct both the depreciated cost and the interest paid on the loan.

How to report the deduction on your taxes

If you are self-employed, you report vehicle deductions on Schedule C (Profit or Loss from Business) as part of your business expenses. The line item is typically "vehicle expenses" or "depreciation," depending on your method.

If you are an employee claiming unreimbursed work expenses, the rules are more restrictive. As of 2018, employees can no longer deduct unreimbursed business expenses on their federal tax return, with rare exceptions (military reservists, performing artists, and government officials have limited deductions). Check with a tax professional if you fall into one of these categories.

If you are claiming medical or charitable mileage, you report it on Schedule A (Itemized Deductions) as a miscellaneous deduction, but only if you itemize rather than take the standard deduction. Medical mileage goes under "medical and dental expenses," and charitable mileage goes under "charitable contributions."

Frequently Asked Questions

Can I deduct a car I bought to drive for a rideshare service like Uber?

Yes, if you use the vehicle primarily for rideshare work. You can deduct either the standard mileage rate for all miles driven while working, or your actual expenses. Keep detailed records of when you are logged into the app and which miles are work-related versus personal. Some rideshare drivers use the standard mileage rate because it is simpler than tracking fuel and maintenance separately.

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

You deduct only the business portion. If you drive 12,000 miles per year and 5,000 are for business, you can deduct 5,000 miles at the business rate. You must track business miles separately from personal miles. The IRS is skeptical of claims that more than 80% of driving is business-related, so keep detailed logs.

Do I have to use the standard mileage rate, or can I always use actual expenses?

You can choose either method in the first year you use the vehicle for business. Once you choose, switching requires IRS permission (Form 3115). Most people stick with their initial choice. The standard rate is easier if you drive moderate distances; actual expenses may save money if you have a luxury vehicle or very high maintenance costs.

Can I deduct a car purchase if I use it occasionally for work?

Only if the work use is significant enough to be your primary use. Occasional work trips do not may have access to. For example, if you drive to a client meeting once a month but use the car for personal errands the rest of the time, you cannot deduct the purchase. You can deduct only those specific business miles at the standard rate.

What happens if I do not have mileage records?

Without contemporaneous written records, you cannot claim the deduction. The IRS will disallow it in an audit. If you forgot to log miles, you can estimate based on your work schedule and typical driving patterns, but this is risky and may not hold up under scrutiny. Start tracking when ready if you have not already.
