Your Car Could Be Saving You Money at Tax Time
Most people know you can deduct mileage on your taxes. Far fewer actually do it — and those who try often leave money on the table because they didn’t track things properly throughout the year. Whether you’re self-employed, a freelancer, or you use your personal vehicle for work-related trips, understanding how mileage deductions work can make a real difference when tax season rolls around.
Who Can Actually Claim It?
Not everyone qualifies, so it’s worth being clear upfront. If you’re a W-2 employee, the 2017 Tax Cuts and Jobs Act eliminated the deduction for unreimbursed employee business expenses at the federal level — at least through 2025. But if you’re self-employed, run a small business, or work as an independent contractor, you’re in good shape.
Common situations that qualify include:
- Driving to meet clients or visit job sites
- Traveling between two workplaces
- Running business-related errands (picking up supplies, dropping off deliveries)
- Medical travel, in certain circumstances
- Driving for charity volunteer work
Your daily commute from home to your regular office doesn’t count. That’s considered personal travel, regardless of how far you drive.
The Two Methods: Standard Mileage vs. Actual Expenses
The IRS gives you two ways to calculate your deduction, and picking the right one can affect how much you get back.
Standard Mileage Rate
This is the simpler option. The IRS sets a rate per mile each year — for 2024, it’s 67 cents per mile for business use. You multiply your total qualifying miles by that rate, and that’s your deduction. No need to track gas receipts, oil changes, or insurance costs separately.
For example, if you drove 8,000 miles for business in 2024, your deduction would be 8,000 × $0.67 = $5,360. Clean and straightforward.
Actual Expense Method
This one takes more effort but can yield a larger deduction if you drive a lot or own an expensive vehicle. You calculate the percentage of miles driven for business versus total miles, then apply that percentage to your actual car-related costs: fuel, insurance, repairs, depreciation, registration fees, and so on.
If your car costs $10,000 a year to operate and 60% of your driving is for business, you can deduct $6,000. The math works in your favor when your vehicle costs are high relative to what the standard rate would give you.
How to Track Your Miles the Right Way
This is where most people slip up. The IRS requires contemporaneous records — meaning you need to log trips as they happen, not try to reconstruct six months of driving from memory in April.
A compliant mileage log should include:
- The date of each trip
- The starting and ending location
- The business purpose of the trip
- The number of miles driven
You don’t need to be fancy about it. A simple spreadsheet works fine. But if you want something more automatic, apps like MileIQ, Everlance, or Stride track your trips via GPS and let you swipe to classify each one as business or personal. They generate reports that are audit-ready, which is a nice layer of protection if the IRS ever comes knocking.
Claiming the Deduction on Your Return
Self-employed individuals report vehicle expenses on Schedule C, under “Car and truck expenses.” If you’re using the standard mileage rate, you’ll enter your total business miles and the IRS does the math. With the actual expense method, you’ll need to fill out Form 4562 if you’re claiming depreciation.
Keep your mileage logs and any supporting documentation for at least three years after filing — that’s the standard window the IRS has to audit a return.
A Few Things People Often Miss
One trip type that gets overlooked: driving from your home office to a client location. If your home is your principal place of business, that trip qualifies. The same goes for trips to the bank, post office, or office supply store when the purpose is clearly business-related.
Also, if you start the year using the standard mileage rate, you can switch to actual expenses in a later year. But if you use actual expenses first, you’re locked out of the standard mileage rate for that vehicle going forward.
Small details like these add up. The mileage deduction isn’t complicated once you understand the rules — the real work is just staying consistent with your tracking throughout the year. Build the habit early, and you’ll have everything you need when it counts.
