What are the 2025 IRS mileage rates for business use?

The 2025 mileage rates set by the IRS are 70 cents per mile for all miles of business use (business standard mileage rate), 14 cents per mile for charitable activities, and 21 cents per mile for medical or military moving purposes. These standardized rates are crucial for small business owners because they offer a way to manage vehicle expenses, ensuring precise reimbursements and tax deductions.

That’s how much US businesses lose annually due to expense fraud, according to a survey by Chrome River ^[1]. With over 6% of employees submitting incorrect expense claims ^[2] and nearly one in four employees admitting to expense fraud ^[3], American businesses are bleeding money.

Do you know what’s a common culprit?

Mileage reimbursement.

Data from TripLog ^[4] shows that nearly 30% of travel reimbursement claims by employees over-report miles. Between January 2018 and January 2021, approximately 2.8 million trips were over-reported, inflating mileage by 27.2%, or about 14.26 million miles.

Accurate mileage logs are essential for maximizing tax deductions, ensuring compliance with IRS regulations and a smooth tax season. Misreporting mileage can lead to lost deductions or even audits, which can be costly and time-consuming.

As a small business owner, you could be making many costly errors, including losing hard-earned money if you are not diligent with bookkeeping and expense tracking as these inaccuracies can significantly impact the bottom line. Self-employed individuals, including freelancers and contractors, should also pay close attention to their mileage tracking.

This blog will discuss the 2025 IRS mileage rates, show you how to calculate mileage reimbursement, and provide tips to help you avoid the pitfalls of inflated expense claims.

What is mileage reimbursement?

The IRS mileage rate, sometimes referred to as the federal mileage rate or mileage reimbursement rate, is established by the Internal Revenue Service (IRS)^[5].

This rate provides a standardized method for calculating deductible vehicle expenses for business purposes, and employers compensate employees for using their personal vehicles for business-related activities. This compensation is calculated based on the miles driven and includes vehicle-related expenses incurred during business operations.

For instance, if an employee drives from the main office to a client’s location for a business meeting, they qualify for mileage reimbursement.

The IRS mileage rate simplifies the process for taxpayers by providing a straightforward way to determine deductible mileage expenses. By following the IRS guidelines for mileage deductions, both employees and employers can ensure they are claiming the correct amount, which helps reduce the risk of audits or penalties for inaccurate reporting.

For small business owners, understanding and utilizing the IRS mileage rate is crucial. It helps in accurately reimbursing employees and serves as a benchmark for setting fair reimbursement rates.

What is considered business mileage?

Here’s a breakdown to help you avoid any confusion about what classifies as business mileage and what doesn’t.

What counts as business mileage:

• If you travel from your main office to a secondary office.
• Any trips taken specifically for meeting clients or attending business conferences.
• If you travel from your home to a temporary office location.

What doesn’t count as business mileage:

Your regular commute from home to your normal office does not qualify.

Special consideration for home-based businesses:

If you’re self-employed or an independent contractor and your home is your primary place of work, it qualifies as an office. This means you can deduct mileage between your home and another work location as long as it’s for the same business.

What is the current IRS mileage rate for 2025?

Staying updated on the IRS mileage rate is essential for small business owners and self-employed individuals who use vehicles for work purposes.

On Dec. 19, 2024, the IRS has announced the standard mileage rates for 2025 as follows:

• Business: 70 cents per mile.
• Charity: 14 cents per mile.
• Medical and/or moving: 21 cents per mile.

These rates are determined based on an annual study of the fixed and variable costs of operating an automobile, which we will discuss in the later sections. The business mileage rate includes variable costs such as gas but does not account for fixed costs like insurance, which remain constant regardless of mileage.

Here are a couple of things to keep in mind:

• The standard mileage rates apply to vehicles running on electricity, hybrids, and diesel and gas.
• For moving purposes, the rate is specifically for active-duty members of the Armed Forces moving under orders to a permanent change of station.
• If you use other types of vehicles (including motorcycles and boats) for business, you can still deduct your expenses, but you must use the actual expenses method instead of the standard mileage rate.

What records do you need for mileage reimbursement?

To ensure accurate mileage reimbursement, the IRS requires you to keep detailed records of the following:

• Date: When the travel occurred.
• Destination: Where you traveled to.
• Purpose of travel: The business reason for the trip.
• Odometer readings: Record the start and stop readings, and calculate the total miles traveled.
• Type of expenses incurred: Document any related expenses.
• Expense amount paid: The total cost of the expenses.

If you have an employer, they might have additional requirements based on their reimbursement policy, so it’s important to check with them in advance.

Here’s an example of a daily business mileage and expense log according to IRS guidelines:

Best mileage reimbursement practices for employers

Understanding mileage reimbursement rules is crucial for you as an employer, particularly if your business exists in states like California, Massachusetts, and Illinois, where reimbursement is mandated. While federal law does not require mileage reimbursement, providing it can foster positive employer-employee relationships.

Keep in mind that not reimbursing work-related mileage expenses could lead to legal consequences if it causes employees’ net income to fall below the federal minimum wage.

Reimbursing your employees for mileage isn’t just for their benefit; it favors you too. The reimbursed amounts can be deducted as business expenses which can lower the taxable income for the business, potentially reducing the amount of taxes owed.

You have flexibility in choosing the reimbursement method that suits your company policies. The IRS standard mileage rate for 2025 is 70 cents per mile, but you can set your own flat rate, which can be higher or lower than the IRS rate.

There are alternative methods for reimbursing mileage, such as mileage allowances or the Fixed And Variable Rates (FAVR) method:

• Monthly mileage allowance: Paid in advance to cover the month’s business mileage expenses.
• Fixed and Variable Rates (FAVR) Method: Combines a fixed cost (insurance, depreciation) and a variable cost (fuel, oil) typically calculated per mile.

Here’s what you should do as an employer:

• Establish a clear reimbursement policy: This should include how employees can log their business mileage, covering details like dates, miles traveled, destinations, and the purpose of each trip.
• Set reimbursement rates: Ensure that any mileage reimbursement does not exceed the IRS-approved rate to avoid the excess being treated as taxable income for the employee.

Since the Tax Cuts and Jobs Act of 2017, W-2 employees cannot claim mileage expenses as tax deductions, a rule in place until January 1, 2026. However, certain groups such as Reserves of the Armed Forces and state or local government officials paid on a fee basis are exceptions and may still deduct unreimbursed travel expenses using the standard business mileage rate.

By implementing a fair and comprehensive mileage reimbursement policy, you not only comply with applicable laws but also support your employees in managing their work-related expenses effectively.

For self-employed individuals

Self-employed individuals have different rules. If a vehicle is used solely for business, all related expenses are deductible. For mixed-use vehicles, only expenses incurred during business use can be deducted.

How to calculate your mileage reimbursement – Standard mileage rate vs actual expenses for business

There are two methods to calculate mileage for tax deductions:

1. Standard mileage rate method: Calculate the deduction based on the standard IRS mileage rate.
2. Actual expense method: Deduct the actual costs of using the vehicle for business purposes, such as gas, maintenance, repairs, and depreciation. This method is more complex and requires thorough record-keeping.

Let’s break them down with examples to illustrate how you can calculate your mileage reimbursement.

Standard mileage rate method

Calculating your mileage reimbursement is pretty simple when following the IRS standard reimbursement rules.

Here’s how it works:

Suppose you’ve traveled 500 miles in a month, and 200 of those miles are for business purposes.

The IRS standard mileage rate for 2025 is 70 cents per mile.

To calculate your mileage reimbursement:

70 cents × 200 business miles = $140

Using the standard mileage method, you can deduct $140 as your mileage tax deduction for the month.

Actual expense method

The actual expenses method is a bit more complicated and requires detailed record-keeping of all vehicle-related expenses such as fuel, maintenance, repairs, insurance, depreciation, and more.

Here’s how you can calculate your deduction using this method:

Suppose you spend around $800 monthly on fuel, maintenance, insurance, depreciation, etc.
You’ve driven a total of 500 miles, with 200 of those miles being for business purposes.

To calculate your deduction:

1. Determine the total business miles driven: 200 miles
2. Calculate the business use percentage: (200 ÷ 500) × 100 = 40%.
3. Calculate the deduction by multiplying the total actual expenses by the business use percentage:

$800 × 40% = $320

Using the actual expenses method, you can deduct $320 as your mileage tax deduction for the month.

How to manage a mileage reimbursement policy

Understanding mileage reimbursement and its calculation is just the first step. As an employer, it’s essential to create a clear mileage reimbursement policy for your employees to follow.

Your policy should cover everything from mileage rates and reimbursable expenses to the necessary records employees need to keep and how to track them.

Here are some tips for creating and managing mileage reimbursements in your business:

1. Effectively communicate your mileage reimbursement policy: Clearly explain how to track mileage, the rules employees must follow, whom to contact for issues, and how reimbursements will be paid.
2. Ask employees to record all business-related trips: Ensure records include the date, total miles driven, odometer readings before and after the trip, the trip’s purpose, and any other incurred expenses.
3. Automate the process with mileage tracker software: Get user-friendly software that can automatically track distance traveled, record trip purposes, deduct commuting miles, enforce policies, and help employees manage their mileage reimbursements effortlessly.

How does the IRS set the mileage rate?

The IRS sets these rates based on a thorough data analysis to estimate transportation costs. Understanding the current mileage rate is essential whether you’re a business owner reimbursing employees for travel or an individual looking to deduct mileage on your taxes.

• Gas prices: Since fuel is a major cost directly tied to mileage, fluctuations in gas prices can significantly impact annual rates. Unexpected spikes or drops in fuel prices can alter projections and adjustments.
• Vehicle maintenance: Costs for parts, labor, and tires also play a role. When these costs rise, the mileage rate increases to cover the gap. Conversely, improvements and cost reductions in maintenance can slow the rate of growth.
• Insurance premiums: Trends in vehicle and commercial rideshare insurance pricing are factored into the mileage deduction. Changes in insurance premiums can influence the mileage rate set by the IRS.
• Inflation: High inflation in transportation costs boosts the mileage rates to keep up with the increasing expenses. Conversely, low inflation contributes to a slower growth rate.
• Used car prices: The cost of used cars affects depreciation costs factored into the mileage rate. Higher used car prices lead to higher depreciation costs and thus higher mileage rates.
• Tax policy: Changes in the tax code regarding business mileage can influence yearly rate decisions. Any alterations to tax policies can have a direct impact on the mileage rate.
• Industry factors: Wider economic or industry issues that affect personal transportation costs also play a role. These can include anything from supply chain disruptions to changes in demand for personal vehicles.

Usually, the factors discussed above are considered when setting each year’s rate. However, inflation and gas prices were the key influencers for the 2025 IRS mileage rates. As for the charity rate, it has been set by statute and has not changed since 1998. To learn more, read: 2025 standard mileage rates.^[7]
