Automobile Expense Deductions for Small Businesses: A Guide with Examples

5 Key Points

  1. Choose Wisely: The standard mileage rate and actual expense method offer different advantages. Consider your vehicle type, mileage, and recordkeeping capabilities when selecting the most beneficial approach.
  2. Document Everything: Accurate mileage logs and expense receipts are essential, especially if you use your vehicle for both personal and business purposes.
  3. Heavier Vehicles, Bigger Breaks: If your business relies on vehicles with a GVWR over 6,000 pounds, explore the potential for significant deductions under Section 179 and bonus depreciation.
  4. Honesty is Key: The IRS takes auto deductions seriously. Inflate your business use percentage at your own risk.
  5. Spend Strategically: The best way to maximize your bottom line is to spend money wisely in the first place. Prioritize necessary expenses that generate a return for your business.

Small Business Tax Deduction Primer

First, let's briefly explain a deduction because they are often simplified in popular media to make it seem like when something is deductible, it is free. 

Small businesses can deduct certain business expenses from their taxable income, lowering their overall tax burden. However, it's important to understand that a tax deduction isn't a magic bullet for saving money. It doesn't eliminate the cost itself but offers a discount on your spending. The discount is based on your tax rate, so a higher tax bracket yields a larger "savings" on the deduction. While deductions are valuable, responsible spending is the best way to save money. By being frugal and minimizing unnecessary business expenses, you reduce the overall amount you need to spend, maximizing the income you realize. 

Auto Deduction Methods and Numeric Examples

Now on to autos; Small businesses can deduct vehicle expenses using one of two methods approved by the IRS: the Standard Mileage Rate method or the Actual Expense method. The choice of method can affect the ease of recordkeeping and the deduction amount.

1. Standard Mileage Rate Method:

The IRS sets an annual standard mileage rate to calculate business auto use deductions. For 2023, this rate is 65.5 cents per mile driven for business purposes. 

Example:

Imagine you drove 5,000 miles for business purposes in 2023. Using the standard mileage rate, your vehicle expense deduction would be:

5,000 miles×$0.655/mile=$3,2755,000 miles×$0.655/mile=$3,275

This method requires less detailed recordkeeping, but you must keep a log of the business miles traveled.

This method can be particularly beneficial for businesses that use smaller, fuel-efficient vehicles. For example, a flower company using a 7-year-old Prius for deliveries might find that actual maintenance and fuel costs are lower than the standard mileage deduction amount. Toyotas are known for their reliability and efficiency, further maximizing the benefit of taking the standard rate. The method is also straightforward, minimizing the business's bookkeeping requirements. 

The IRS provides updates on the standard mileage rate annually in publications such as Notice 2023-03. More details can be found on their website: IRS Standard Mileage Rates.

2. Actual Expense Method:

This method involves deducting all expenses related to the vehicle's operation and allocating them according to the percentage of business use based on miles driven.

Example:

Suppose your total vehicle expenses for the year (including gas, repairs, insurance, and depreciation) amount to $9,000. If 70% of the total 10,000 miles driven were for business, your deduction would be:

$9,000×70%=$6,300$9,000×70%=$6,300

This method requires comprehensive recordkeeping of all expenses and mileage logs to substantiate business use proportion. This method is most advantageous when the vehicle's operating costs are high due to maintenance costs, low gas mileage efficiency, or a costly vehicle being involved. 

Relevant IRS Information:

Details on what expenses are deductible and how to calculate them can be found in IRS Publication 463 (Travel, Gift, and Car Expenses), available at IRS Publication 463.

Addressing Personal Use

Personal use of a business vehicle complicates deductions. Only the portion of expenses attributed to business use is deductible. It's essential to keep detailed records distinguishing between business, commuting, and personal miles.

Example:

If you drive your vehicle 12,000 miles in a year, with 8,000 miles for business, 2,000 miles for commuting, and 2,000 miles for other personal use, the business use percentage is:

8,000 miles12,000 miles×100%=66.7%12,000 miles8,000 miles​×100%=66.7%

Your deductible expenses will be 66.7% of the total actual expenses incurred during the year.

Tax Breaks for Vehicles Over 6,000 Pounds

This is another TikTok favorite rule to cite,, and it is true: Under certain IRS rules, heavier vehicles qualify for more significant tax deductions.

1. Section 179 Deduction:

Vehicles with a GVWR over 6,000 pounds used more than 50% for business purposes qualify for the Section 179 deduction, which allows for an immediate expense deduction.

Example:

You buy a new SUV for business use at $50,000 and use it 80% for business. The maximum Section 179 expense deduction for 2023 is $27,000 for vehicles over 6,000 pounds. Thus, your potential deduction is:

$27,000×80%=$21,600$27,000×80%=$21,600

Relevant IRS Information:

The latest updates and limits for the Section 179 deduction can be found in IRS Publication 946 (How to Depreciate Property), accessible at IRS Publication 946.

2. Bonus Depreciation:

This allows for an additional deduction in the first year of use, which can be up to 100% for new vehicles. But again, this is only applicable to the business portion of the asset, not the personal use

Example:

Suppose the SUV in the previous example is new. In that case, you might claim the entire business-use portion ($40,000) as a bonus depreciation in the first year.

They are on the IRS Radar

Be careful. The IRS closely scrutinizes automobile deductions because they are a common target for abuse. Taxpayers often overstate the business use percentage of their vehicles, leading to inflated deductions. This can happen intentionally for fraudulent purposes or unintentionally due to poor recordkeeping. Because of this potential for abuse, the IRS pays extra attention to vehicle-related deductions during audits.

Truely Maxiumizing Small Business Income

Do you really need to spend it? By understanding these methods and leveraging available tax breaks, small businesses can reduce their taxable income. However, the absolute best way to increase your business income is through a mindset of frugality. Before making any purchase, ask yourself: Is this expense truly necessary for the success of my business? Will it generate a return on investment? Often, the greatest profit boost doesn't come from complex tax strategies, but from the simple discipline of avoiding unnecessary spending.  

Consulting with a tax professional for specific guidance tailored to your business situation is advised.
