Can I Write Off My Car as a Business Expense in Houston? A Complete Tax Guide for 2025
You can write off your vehicle expenses in full or in part against your income at tax time if you use the car for business. This kind of deduction can be a source of good savings for many self-employed professionals and small business owners in Houston. However, the IRS scrutinizes vehicle deductions, and erroneous claims could lead to audits or penalties.
Wondering if you can write off your car as a business expense in Houston? Here's a guide that will take you through everything Houston entrepreneurs need to know regarding car-related tax write-offs in 2025. Working with expert tax preparation services in Houston, TX, will help to tackle compliance with these deductions.
Who Can Write Off Car Expenses?
If you are self-employed, a sole proprietor, an LLC, or operating an S-Corp, and you use your personal or company car for business activity, you're eligible to deduct vehicle expenses. However, a quick note: commuting to and from your primary place of employment simply cannot be deducted as business mileage. Instead, potential deductions include:
· Driving to client meetings
· Traveling between job sites
· Picking up supplies for the business
· Attending conferences or industry events
To write off any car expenses properly, you will need to know how much you use the vehicle for business and how much for personal activities. This percentage must be accurate, and tax preparation services for small businesses in Houston can help you figure out this ratio and justify it.
Standard Mileage Vs. Actual Expenses
The IRS gives you two methods for writing off vehicle costs: the Standard Mileage Rate and the Actual Expense Method. You need to pick an option wisely, considering its impact on tax savings.
1. Standard Mileage Method
With this method, a standard rate per business mile is allowed as a deduction. This rate is set by the Internal Revenue Service (IRS) for each calendar year. As of 2025, the rate is set at 70 cents per mile for self-employed individuals and businesses, with an expected update for 2026.
This method is easy to use and is best for people with low operating costs who don't want to keep track of every receipt. One must still prove and provide a detailed mileage log.
2. Actual Expense Method
In this option, you can deduct the actual costs for operating the vehicle, which may include:
Fuel
Oil changes
Repairs and maintenance
Tires
Car insurance
Depreciation (for owned vehicles)
Lease payments (for leased vehicles)
The proof of these expenses should be in detail, and there should be receipts to support the claims. Expert tax preparation services in Houston, TX, can assist in comparing the two options and then help you select the most advantageous one while complying with the IRS.
Documentation You’ll Need for Vehicle Deductions
Documentation is a must, irrespective of which method you choose. The IRS needs exact records to support every business vehicle claim. As a taxpayer, if your records are missing or expenses remain unsupported, you may face a series of tax audits.
Documents should include the following:
A mileage log with the date, purpose, starting point, and miles driven for each business trip.
Receipts for gas, oil, insurance, maintenance, and repairs.
Year-end odometer readings.
Invoices or meeting notes to justify business-related travel.

Vehicle Purchases and Sales Tax in Texas
Texas imposes a motor vehicle sales tax of 6.25% on purchases. For business-owned vehicles, this sales tax may be deductible or even avoidable in specific contexts, depending on how the vehicle is titled and used.
If you’re buying a vehicle specifically for your business, you might also need to deal with sales and use tax services in Houston, TX, to ensure proper filings with the Texas Comptroller’s office. For example:
Was the vehicle used for resale?
Are you leasing it?
Are you paying tax upfront or over time?
A lot of business owners end up misclassifying their purchases unknowingly and face problems later on. When you opt for expert sales tax compliance services in Houston, Texas, you can set up your purchase in a way that provides maximum deductions and deters any state-level penalties.
What You Shouldn’t Do When Writing Off Vehicle Expenses
Even seasoned business owners sometimes make mistakes when writing off vehicle expenses. Here are some of the most common pitfalls, and how to avoid them:
Combining personal and business mileage without a clear split
Double-dipping by claiming both mileage and actual expenses
Failing to document trips with a detailed mileage log
Not accounting for depreciation when using the actual expense method
Incorrectly handling leased vehicles vs. purchased ones on the return
With such mistakes, you may end up inviting IRS red flags. With Skyline’s tax preparation services for small businesses in Houston, you’ll know exactly what to track and how to report it correctly.
