Business Vehicle Expenses: Buy, Lease, Deduct Smarter

Buying or leasing a vehicle through your business can unlock major deductions — but how much you save depends on what you buy, how you pay, how much you use it for work, and how you track it. We’ll help you navigate the rules, avoid common mistakes, and keep more of what you earn.

🛍️ Buy vs. Lease: Which Strategy Fits You?

There’s more to life than taxes. When deciding whether to buy or lease a vehicle, it’s important to keep your priorities in mind:

‍

Goals:

‍

Preserve cash now

✔️ Lower monthly outflow.

❌ Higher upfront cost.

‍

Maximize early deductions.

‍❌ Lease payments spread out

✔️ Bonus depreciation if >50% business use.

‍

Drive luxury or light vehicles.

‍✔️ Avoids depreciation caps

❌ May hit luxury car deduction limits.

‍

‍Long-term asset ownership.

‍❌ No equity at end of lease

✔️ You own it and keep resale value.

‍

‍Keep things simple

‍✔️ Standard deduction of lease cost

❌ Requires asset tracking and depreciation schedules.

‍

🚘 If You Buy

Heavyweight bonus

‍

Vehicles over 6,000 lbs (think Range Rover, Tahoe, F-150) aren’t subject to luxury car limits. These can qualify for 60% bonus depreciation in 2025, potentially giving you a huge write off in year one.
Lighter vehicles are subject to luxury auto depreciation limits, capping deductions at around $20K in early years and even less over time.

‍

You don’t need to pay cash

‍

You don’t need to pay in full to maximize your depreciation deduction. As long as the vehicle is placed in service by year-end and primarily used for business, you can still take full bonus depreciation, even if you finance it.

‍

Strategy Unlocked: When you finance a heavy vehicle used primarily for business, your tax deduction could outperform your cash flow in early years.

‍

📄 If You Lease

Deduct payments based on business use - ideal for lower-mileage drivers or those who like to change vehicles frequently.
No large upfront deduction, but easier to budget month-to-month.

‍

⚖️ Choosing the legal owner

Business-owned vehicles are eligible for full business deductions, but commercial insurance may cost more.
Personally owned vehicles are still eligible for the same deductions, but require careful documentation of business use and record-keeping of costs for reimbursement.

‍

Bottom line: If you want big write-offs and drive a qualifying vehicle more than 50% for business, buying is usually better. If you want flexibility, lower commitment, and simplicity, leasing can make more sense.

‍

📊 Business Use %: The Key to Every Vehicle Deduction

No matter what you drive, the percentage of your miles used for business directly impacts your deduction.

‍

To qualify for…

‍

Bonus depreciation or Section 179: You must establish at least 50%+ business use
Any deduction at all: must track and substantiate your business use percent.

‍

You don’t need to track every mile.

‍

Yep, you read that right. Per IRS guidelines, you can:

‍

Record odometer readings at the start and end of the year
Keep a representative mileage log to estimate annual business use
Supplement with calendar, CRM, delivery logs, or appointment records

‍

Example: Instead of tracking every mile, track all of your miles for two typical weeks straight, three times a year. This would be considered acceptable support for your annual business use percent.

‍

🚙 Mileage vs. Actual Expenses: Choose the Best Method

There are two ways to calculate your annual vehicle deduction, the standard mileage method and the actual expense method.

‍

🛣️ Standard Mileage Method

‍

IRS sets the rate (70 cents/mile in 2025)
Covers gas, wear and tear, and maintenance
Easy to use, but often leaves money on the table, especially for expensive or high-mileage vehicles

‍

💰 Actual Expense Method

‍

Deduct a percentage of actual costs based on business use
Acceptable costs include gas, insurance, maintenance, registration, depreciation (if owned), loan interest (if financed through the business) and more
Offers much larger write-offs for newer, heavier, or more expensive vehicles
Required if you want to claim bonus depreciation

‍

Heads up: If you start with the mileage method, you can’t switch to actual expenses later for that same vehicle.
