How do I write off my car with an LLC?

[Aaliyah]

You can write off your car with an LLC by deducting expenses proportional to business use, using either the standard mileage rate or actual expense method. For 2024, the standard rate is 67 cents per mile, rising to 70 cents in 2025. Vehicles over 6,000 lbs GVWR often qualify for significant first-year deductions like Section 179. The key is documenting that the car is used for business purposes over 50% of the time.

The deduction amount hinges on business-use percentage, not whether the car is titled in the LLC's name. Using a personal vehicle for LLC business still allows deductions. The two primary IRS-approved methods are:

Standard Mileage Rate: This is straightforward. You track every business mile driven and multiply the total by the annual IRS rate. It's often best for high mileage or simpler record-keeping, as it bundles costs like depreciation, fuel, and maintenance into one rate.

Actual Expense Method: You track and deduct the precise business-use percentage of all vehicle costs. This includes fuel, insurance, repairs, tires, registration, and depreciation. This method can yield larger deductions if you have a high-value vehicle or significant operating costs, but requires meticulous records.

For new or heavy vehicles, strategic first-year deductions are available:

• Section 179 Deduction: This allows you to deduct the full purchase price of a qualifying vehicle (often those over 6,000 lbs GVWR) in the year it's placed in service, subject to annual limits. For many heavy SUVs, the deduction is currently limited to a specific cap, with the remainder depreciated over subsequent years.
• Bonus Depreciation: This offers an additional percentage of the vehicle's cost that can be deducted in the first year, often used in conjunction with other methods.

Deduction Method	Best For	Key Requirement	How It Works
Standard Mileage Rate	High business mileage; simpler record-keeping	Detailed mileage log	Multiply business miles by IRS rate (e.g., 67¢/mile in 2024)
Actual Expenses	High-value vehicles; lower annual mileage	Receipts for all costs	Deduct business % of fuel, insurance, repairs, depreciation
Section 179	Qualifying heavy vehicles (GVWR > 6,000 lbs)	> 50% business use	Deduct full purchase price up to limits in first year
Bonus Depreciation	New qualifying vehicles	Vehicle must qualify	Additional first-year deduction percentage of cost

Record-keeping is non-negotiable. You must maintain a contemporaneous mileage log for every business trip, noting date, destination, purpose, and odometer readings. For actual expenses, keep all receipts and invoices. Without this documentation, deductions may be disallowed during an audit.

Tax laws are complex and change. The strategies mentioned, such as the specific deduction cap for heavy SUVs, are based on current statutes. Consulting with a qualified tax professional is essential to apply these rules correctly to your LLC's specific circumstances.

As a small business owner, I use the standard mileage rate. It’s just easier. I have an app on my phone that logs every trip automatically when I drive to see a client, pick up supplies, or go to the bank for the LLC. At tax time, my accountant just needs the total business miles from the app and multiplies it by the IRS rate. I don’t have to save every gas or oil change receipt. The critical part is making sure the log app notes the reason for the trip—that “business purpose” is what the IRS looks for.

Think of it as separating your car’s life into two parts: business you and personal you. The IRS only lets your business-self deduct costs. If you drive 10,000 miles a year and 7,000 are for your LLC, that’s 70% business use. You can then deduct 70% of your total annual car costs (gas, insurance, depreciation) through the actual expense method. The alternative is the mileage method, which pays your business-self a flat rate per mile. Which is better? If you drive an older, fuel-efficient car a lot for business, the mileage rate is often better. If you just bought a new, expensive truck or SUV for work and don’t drive it excessively, deducting the actual expenses (especially with first-year bonus depreciation) usually saves more.

The biggest mistake is poor records. An IRS auditor won’t accept a handwritten estimate. You need a log—digital or paper—for every business trip. Date, miles, where you went, why. “Meeting with client X” or “delivery to job site Y.” Also, understand the “listed property” rules. If your vehicle is titled under the LLC but you use it less than 50% for business, you cannot use accelerated depreciation methods like Section 179. The deductions must be spread over the standard depreciation schedule. Always confirm the current year’s standard mileage rate and Section 179 limits with your tax advisor, as these figures adjust annually.

My LLC owns our work truck outright. We went the actual expense route because it qualified for the Section 179 deduction. Since its gross vehicle weight is over 6,000 pounds, we were able to write off a large portion of the purchase price in the first year itself. Our bookkeeper tracks everything: every gallon of diesel, every maintenance invoice, and the insurance premium. We allocate 90% of those costs as a business expense because that’s our documented business-use percentage. The key is that the LLC pays for all these expenses directly from its business account. Mixing personal and business payments for a vehicle, even if it’s LLC-owned, creates a bookkeeping nightmare and can jeopardize the deductions. We keep it clean.
