How to Deduct Your Vehicle the Right Way as a North Dallas Business Owner

For a lot of business owners in Carrollton, Plano, Frisco, and across North Dallas, their vehicle is one of their biggest business tools. Contractors drive to job sites. Consultants drive to client meetings. Sales professionals drive all over the Metroplex every week. The good news is that the IRS allows you to deduct the business use of your vehicle. The important word there is business use.

The Two Methods: Standard Mileage vs. Actual Expenses

There are two ways to deduct vehicle expenses. The standard mileage method is simpler: you multiply your total business miles by the IRS standard mileage rate for that year. The actual expense method lets you deduct a percentage of your actual vehicle costs (fuel, insurance, maintenance, registration, depreciation) equal to your business use percentage.

If you drive a vehicle that is exclusively used for business, the actual expense method typically yields a larger deduction, especially for expensive or heavily maintained vehicles. If you also use the vehicle personally, you need to calculate your business use percentage accurately.

You Must Track Your Mileage

This is where most people fall short. The IRS requires a contemporaneous mileage log: a record kept as you drive that shows the date, destination, business purpose, and miles for each business trip. Reconstructing your mileage from memory at the end of the year is not sufficient and will not hold up in an audit.

There are several mileage tracking apps that make this automatic. MileIQ, Everlance, and similar tools run in the background and log your trips automatically. This is one of those small habits that pays for itself every single tax season.

Commuting Miles Are Never Deductible

Driving from your home to your regular office or primary place of business is commuting, and commuting miles are not deductible regardless of how far you drive. This is one of the most common misunderstandings we see. However, if you drive from your office to a client's location, that is a deductible business trip. If you work from a home office, driving from home to a client location can be deductible.

Section 179 and Bonus Depreciation for Vehicles

If you purchase a vehicle for business use, you may be able to deduct a significant portion of the purchase price in the year of purchase using Section 179 expensing or bonus depreciation. For heavy vehicles with a gross vehicle weight rating above 6,000 pounds, the deduction limits are higher. Many trucks, SUVs, and vans common in the North Dallas trades community qualify for these accelerated deductions.

However, if you use the vehicle for both business and personal purposes, only the business-use percentage of the deduction applies. A vehicle that is 70 percent business use generates a deduction for 70 percent of the eligible amount.
