For many businesses, the use of vehicles for work-related travel is a daily necessity. Whether it's visiting clients, traveling between job sites, or running business errands, these trips accumulate mileage. The Internal Revenue Service (IRS) allows businesses and self-employed individuals to deduct the costs associated with this business mileage. Understanding how to categorize and claim these "mileage expenses" is crucial for accurate bookkeeping and tax optimization.

This guide will explain what mileage expenses entail, important considerations for claiming them, examples of deductible mileage, the tax implications, and how a modern expense management tool like Fyle can help automate and simplify the tracking process.

Mileage Expenses Category

"Mileage Expenses" typically refer to the deduction a business or self-employed individual can claim for the business use of a car, van, pickup, or panel truck. This deduction isn't usually a direct sum of receipts for "miles" but is calculated using one of two IRS-approved methods:

  1. The Standard Mileage Rate Method: This is a simplified method where you multiply the number of business miles driven by a standard rate set annually by the IRS (e.g., 67 cents per mile for business use in 2024 ). This rate is designed to cover various vehicle operating costs, including depreciation (or lease payments), maintenance and repairs, gasoline (including taxes), oil, insurance, and vehicle registration fees.
  2. The Actual Expense Method: This method involves tracking and deducting the actual costs of operating the vehicle for business purposes. These costs include gasoline, oil, repairs, tires, insurance, registration fees, licenses, depreciation (or lease payments), and other miscellaneous vehicle-related expenses.

When recorded in an accounting system, the deduction calculated (whether via standard rate or actual expenses) typically falls under categories like:

  • Car and Truck Expenses
  • Vehicle Operating Expenses
  • Travel Expenses (if the mileage is part of an overnight business trip)

Some Important Considerations When Claiming Mileage Expenses

Business Mileage Expense Considerations

Business Purpose is Paramount

Only mileage for trips directly related to your trade or business is deductible. Personal trips, including regular commuting between your home and primary workplace, are generally not considered business mileage.

Choosing Between Standard Mileage Rate and Actual Expenses

  • Standard Rate: Offers simplicity as you don't need to track every single vehicle operating cost. However, you must choose this method in the first year the car is available for use in your business if you own the car, to retain flexibility to switch to actual expenses in later years. For a leased car, if you choose the standard rate, you must use it for the entire lease period.
  • Actual Expenses: May result in a larger deduction for some, especially if vehicle costs are high, but requires meticulous tracking of all individual expenses. If you use an accelerated depreciation method (like MACRS other than straight-line) or claim a Section 179 deduction in the first year for a car you own, you cannot switch to the standard mileage rate for that car in subsequent years.

Tolls and Parking Fees

Regardless of whether you use the standard mileage rate or the actual expense method, business-related parking fees and tolls can be deducted separately.

Meticulous Recordkeeping

The IRS requires detailed, contemporaneous records to substantiate mileage deductions. This is crucial for both methods. Your records should show:

  • The date of each business trip.
  • Your starting point.
  • Your destination.
  • The business purpose of the trip.
  • The mileage for each business trip.
  • Total miles driven during the year (business, commuting, and other personal miles).
  • Odometer readings (start and end of the year, and ideally for each trip).

Commuting Miles

Daily transportation expenses incurred traveling between your home and your main or regular place of work are considered personal commuting expenses and are not deductible. However, mileage between two different business locations during the same day, or from your home to a temporary work location outside your metropolitan area (if you have no regular place of work), or from your qualifying home office to another work location in the same business, may be deductible.

Employee Reimbursements for Mileage

If an employer reimburses employees for business mileage using their personal vehicles, these reimbursements are generally non-taxable to the employee and deductible by the employer if made under an accountable plan. An accountable plan requires employees to substantiate their mileage (date, place, purpose, mileage) and return any excess allowance within a reasonable time. Reimbursements up to the standard IRS mileage rate are generally considered substantiated for amount.

Examples of Deductible Mileage Expenses

The following are common situations where mileage driven can be considered a deductible business expense:

  • Driving from your office to a client's location for a meeting or service call.
  • Traveling between different branches or work sites of your business.
  • Driving to a temporary work location (e.g., a specific project site) if you have a regular place of business.
  • If your home office qualifies as your principal place of business, mileage from your home to visit clients or conduct other business activities.
  • Driving to attend a business conference, seminar, or trade show (as part of deductible travel expenses).
  • Mileage for business-related errands, such as trips to the bank, post office, or to pick up business supplies.

Tax Implications of Mileage Expenses

Standard Mileage Rate

  • You deduct an amount equal to your business miles driven multiplied by the applicable IRS standard mileage rate for the year (67 cents per mile for 2024).
  • This rate includes an allowance for depreciation. Therefore, if you use the standard rate, you cannot separately deduct depreciation or most actual operating costs. You must reduce the basis of your vehicle by the depreciation component of the standard rate used. (IRS Publication 463, Chapter 4 provides a table for the depreciation rate allowed in the standard mileage rate for different years ).
  • Business-related parking fees and tolls are deductible in addition to the standard mileage rate amount.

Actual Expense Method

  • You deduct the business-use percentage of all actual vehicle operating costs. This includes gas, oil, repairs, tires, insurance, registration fees, licenses, and depreciation (or lease payments).
  • Depreciation deductions are subject to limits, especially for passenger automobiles (see IRS Publication 946 for details on MACRS, Section 179, and special depreciation allowances).

Recordkeeping is Non-Negotiable

For both methods, the IRS requires detailed and contemporaneous records of your business mileage, including dates, destinations, business purposes, and odometer readings. Without adequate records, your deduction may be disallowed.

Reporting

  • Sole Proprietors: Report car and truck expenses (whether using standard rate or actual expenses) on Line 9 of Schedule C (Form 1040). Part IV of Schedule C or Form 4562 (Depreciation and Amortization) must be completed to provide details about vehicle usage and depreciation if claimed.
  • Eligible Employees: Certain employees (Armed Forces reservists, qualified performing artists, fee-basis state/local government officials) report unreimbursed mileage expenses on Form 2106, Employee Business Expenses.
