Can You Claim a Mileage Deduction for Unreimbursed Business Mileage on Your Tax Return?

Do you drive for work and wonder if those miles can save you money on taxes? Mileage deductions are a valuable tax break, but not all trips qualify. With the latest IRS guidelines for 2025, understanding what’s deductible and how to claim it is more important than ever. In this article, explore the rules to help you maximize your tax benefits and ensure you’re not leaving money unclaimed.

What is Considered Deductible Mileage by the IRS?

Types of Business Mileage That Qualify for Deductions

1. Client Meetings and Customer Visits
   If you drive your vehicle for business purposes, such as meeting clients or customers, the IRS considers this deductible business mileage. For example, driving to a client’s office to close a deal or deliver a service qualifies under the mileage deduction rules. Keep a detailed mileage log that includes the date, destination, and purpose of the trip.
2. Traveling Between Multiple Workplaces
   For small business owners or those who are self-employed, any miles driven between two places of business are tax-deductible. This is particularly relevant for those filing a Schedule C for the tax year 2025. However, ensure these trips are for business purposes, as the IRS will want to see clear documentation of these work-related travels.
3. Driving to a Temporary Worksite
   If you’re working at a location expected to last less than one year, you can claim mileage on taxes for the miles driven. For instance, contractors or freelancers often qualify for this mileage tax deduction. These trips can add up quickly throughout the year, resulting in significant tax savings when you deduct mileage.

Non-Deductible Mileage: Understanding the Rules

1. Commuting From Home to a Regular Workplace
   Driving to your regular place of business from home is considered commuting, and commute mileage is not deductible. Even if you’re using your vehicle to carry tools or equipment, the IRS considers these trips personal and not eligible for a mileage rate deduction.
2. Misconceptions About Car Advertising and Commuting
   Placing a business logo or advertisement on your car does not make your commute deductible. Similarly, hauling tools or supplies during your drive to work doesn’t convert personal commuting miles into deductible mileage. Remember, business miles only apply when the trip’s purpose aligns directly with your business activities.

How Does the Standard Mileage Rate Work in 2025?

The 2025 Standard Mileage Rate: Key Numbers You Need to Know

• The IRS standard mileage rate for business use of your car in 2025 is $0.70 per mile. This rate covers operating expenses like fuel, depreciation, and maintenance for trips made specifically for business purposes.
• In addition to the rate per mile, you can deduct tolls and parking fees incurred during these trips. However, expenses like gas for personal travel or commuting miles are not included.

How to Use the Standard Mileage Rate to Claim Deductions

1. Step-by-Step Example Calculation
   If you drove 5,000 miles for business in 2025, multiply that by the standard mileage rate:
   • 5,000 miles x $0.70 per mile = $3,500 in mileage tax deductions.
     Add any business-related tolls or parking fees to this total to maximize your deduction.
2. Eligibility Criteria for Using This Method
   • You must own or lease the vehicle.
   • To use the standard mileage rate method, it must be chosen in the first year your car is used for business. After that, you can switch to the actual expense method, but not vice versa.
   • If you’re leasing, you must use the standard mileage rate for the lease’s entire term.

What is the Actual Expense Method for Mileage Deduction?

Deductible Expenses Under This Method

When using the actual car expense method, you can deduct specific costs associated with operating your vehicle for business purposes. These include:

• Depreciation deduction for the vehicle’s wear and tear.
• Fuel and maintenance costs such as oil changes, tire replacements, and repairs.
• Car insurance, registration fees, and licenses required to use your car for work.
• Other costs like garage rent, interest on a car loan, and tolls and parking fees.

Choosing Between Standard and Actual Expense Methods

1. Factors to Consider Based on Car Value and Usage
   • If your car is new or expensive to maintain, the actual expenses method often provides a higher deduction because it accounts for depreciation deductions and other costs.
   • For older or fuel-efficient cars, the standard mileage rate method is simpler and often more beneficial.
2. Restrictions on Switching Between Methods
   • If you use the actual expense method in the first year of business use, you cannot switch to the standard mileage rate in future years.
   • For leased vehicles, the method chosen must be maintained for the lease’s entire duration.

What Records Does the IRS Require for Mileage Deductions?

Tools and Best Practices for Mileage Tracking

1. Using Mileage Tracking Apps for Compliance
   Apps like MileIQ or QuickBooks Self-Employed simplify mileage tracking and ensure you maintain IRS-compliant logs. These tools can automatically track miles, categorize trips, and calculate deductions based on the business mileage rate.
2. What to Log: Dates, Destinations, and Purposes
   For every business trip, record:
   • Date of travel
   • Starting and ending locations
   • Purpose of the trip (e.g., client meeting, delivery, or attending a work-related event)
     This level of detail helps verify your mileage tax deduction if audited.

Ensuring IRS-Compliance: Documentation You Need

1. Odometer Readings for the Year
   At the start and end of the tax year, log your vehicle’s odometer readings. This ensures accurate reporting of mileage driven for both business and personal purposes.
2. Receipts for Tolls, Parking, and Maintenance Expenses
   Keep all receipts for tolls, parking fees, and maintenance related to your vehicle’s business use. These are separate from the cents per mile deduction but can still be added for additional tax savings when using the actual expense method.

Key Takeaways

• Understand What’s Tax-Deductible: If you drive for business, trips like client meetings and temporary worksite visits qualify for a tax deduction for mileage, but mileage to and from work does not.
• Choose the Right Deduction Method: You can claim the IRS standard mileage at the 2025 IRS rate of 70 cents per mile or deduct your actual expenses, like gas, maintenance, and depreciation under the Section 179 deduction.
• Keep Detailed Records: Accurate logs of your annual mileage, odometer readings, and receipts for car and truck expenses are essential for claiming mileage on your taxes and ensuring every deduction you deserve.
• Self-Employed? Maximize Tax Savings: If you’re self-employed, unreimbursed mileage counts as a business expense under self-employed mileage deduction rules, offering significant small business tax benefits.
• Consult a Tax Expert: Whether navigating the Tax Cuts and Jobs Act, handling car for business reimbursements, or ensuring your adjusted gross income includes every write-off, a tax expert can help you get every credit and deduction while staying compliant.
