A lot of business owners assume they can write off everything related to their car. Gas, payments, insurance, repairs, and even the full cost of the vehicle. That’s not exactly how it works.
The rules around vehicle expenses can save you money, but they can also get you into trouble if you don’t understand them. The Internal Revenue Service pays close attention to vehicle deductions because they’re often abused or misunderstood. Let’s clear it up.
You Can Only Deduct Business Use
This is the most important rule. You can only deduct the portion of your vehicle that is used for business. If you use your car 70% for business and 30% for personal use, you can only deduct 70% of the expenses. A lot of people try to write off 100% of their vehicle, even though they use it for everyday personal driving. That’s a red flag. The key is being honest and having a way to support your numbers.
Two Ways to Deduct Vehicle Expenses
There are two main methods to deduct your car expenses. You don’t use both. You choose one. The first is the standard mileage method. This is the simpler option. You track your business miles and multiply them by the IRS mileage rate.
The second is the actual expense method. This includes things like gas, insurance, maintenance, repairs, and depreciation. The mileage method is easier and requires less tracking. The actual expense method can sometimes give you a bigger deduction, but it requires detailed records.
You Can’t Just Write Off Your Car Payment
This is where a lot of people get it wrong. You can’t simply deduct your monthly car payment. Instead, you deduct depreciation, which spreads the cost of the vehicle over time.
If you’re using the actual expense method, a portion of your car’s value may be deductible each year, along with other expenses. But it’s not as simple as writing off the full payment.
Gas and Repairs Are Not Automatically Deductible
Gas, oil changes, tires, and repairs can be deductible, but only under certain conditions. If you’re using the mileage method, these expenses are already built into the mileage rate. You don’t get to deduct them separately. If you’re using the actual expense method, then you can include them, but again, only the business-use percentage.
Trying to claim both methods at the same time is a mistake that can cause problems.
Commuting Does Not Count
Driving from your home to your main place of business is considered commuting. That is not deductible. This surprises a lot of people.
However, driving between job sites, meeting clients, or running business errands can count as business mileage. Understanding the difference is important because commuting miles cannot be included in your deduction.
You Need a Mileage Log
If you’re claiming vehicle expenses, you need records. A mileage log should include dates, destinations, the purpose of the trip, and miles driven. It doesn’t have to be complicated, but it does need to be consistent. Without a log, it becomes difficult to prove your deduction if it’s ever questioned.
This is one of the first things the Internal Revenue Service will ask for if your vehicle expenses are reviewed.
Large Vehicle Write-Offs Can Raise Questions
Some business owners try to write off a large portion of a vehicle all at once. In certain cases, like with heavier vehicles, larger deductions may be allowed. But if it doesn’t match your income or business activity, it can draw attention. The issue isn’t claiming a deduction. It’s making sure the deduction makes sense for your situation.

Final Thought
Your car can be a legitimate business deduction, but it’s not a free write-off. You need to track your usage, choose the right method, and understand what actually qualifies. When done correctly, it can reduce your taxes. When done wrong, it can create unnecessary problems. The goal is simple. Take the deduction the right way and keep it clean.
