Guide to Tax Mileage Deduction for Work Travel

If you're a business owner, self-employed professional, or contractor; understanding the methods and rules for mileage tax deductions is essential for optimizing your tax benefits. Here, we'll explore the ins and outs of deducting mileage, helping you navigate the road to potential tax savings on your tax return.

Who Can Claim the Mileage Tax Deduction?

Prior to the Tax Cuts and Jobs Act (TCJA) of 2017, employees could claim tax deductions in excess of 2% of their adjusted gross income for mileage incurred during their work duties. However, the TCJA instated changes that suspended the deduction for employee business expenses. As a result, most employees are no longer eligible to deduct mileage and other unreimbursed expenses on their taxes.

However, there are still specific groups that retain the ability to deduct business miles driven on their tax returns, including:

  • Small Business Owners. This includes people who operate small businesses and self-employed individuals who file under Schedule C or Schedule F.

  • Other Self-Employed Workers. This category encompasses independent contractors and freelancers.

  • Certain Types of Employees. Qualified performing artists, reservists in the armed forces, and fee-based government officials may still be eligible to claim mileage deductions.

Two Ways of Calculating the Mileage Deduction

There are two methods for computing deductions related to vehicle expenses: Standard Mileage Rate and Actual Expenses.

Standard Mileage Rate Method

The standard mileage rate method is a simplified way to calculate mileage deductions. It offers a fixed rate per mile driven for business purposes. For the 2023 tax year, the Internal Revenue Service (IRS) has issued a standard mileage deduction rate of 65.5 cents per mile. To claim deductions using this method, you must meet the following requirements:

  • Business Travel. The mileage you claim must be for business purposes and may include:

  • Owner or Lessee of the Vehicle. The taxpayer must either be the owner or lessee of the vehicle in question.

    • Owner. If you own the vehicle, you must opt for the standard mileage rate in the initial year the vehicle is available for business use. In subsequent years, you have the flexibility to choose between the standard mileage rate and actual expenses.

    • Lessee. If you have a leased car and choose the standard rate, you're committed to using this method throughout the entire lease period, including any renewals.

  • Record Keeping. While this method simplifies the process, it still requires accurate record-keeping. You should maintain a detailed mileage log as described below.

  • Unreimbursed Mileage. If your client or company reimburses you for mileage expenses, you cannot claim the mileage deduction using this method.

Limitations On Claiming the Standard Mileage Deduction

Some of the limitations that prevent you from claiming the IRS standard mileage rate include:

  • More Than Four Vehicles. Utilizing more than four vehicles simultaneously, such as in fleet operations.

  • Depreciation Deduction. You previously claimed a depreciation deduction for the vehicle using any method other than the straight-line method of depreciation.

  • Section 179 Deduction. You previously claimed this deduction on the vehicle.

  • Special Depreciation Allowance. You previously claimed this allowance on the vehicle.

Note: If you use this method, you can still deduct vehicle loan interest, registration fees, property tax fees, parking fees, and tolls, as long as they are business-related.

Standard Mileage Method Example

Suppose you own a business in Jacksonville, Florida, and during 2023 you drove 25,000 miles for business purposes. By applying the mileage deduction rate of 65.5 cents per mile, you're eligible to claim $16,375 for the year.

Actual Expense Method

The actual expense method offers the potential for more substantial deductions but requires more extensive record-keeping. To qualify to deduct expenses using this method, you must meet the following conditions:

  • Business Use. The same business travel rules apply as stated above.

  • Documenting Expenses. You need to keep a detailed mileage log and detailed records of all the actual costs related to your vehicle. Maintaining receipts and documentation is crucial to substantiate your claims when you use the actual expense method. Allowed deductible costs include:

    • Rental or lease payments

    • Vehicle loan interest

    • Insurance

    • Fuel and oil

    • Maintenance and repairs

    • Tires

    • Licenses

    • Registration fees and taxes

    • Tolls and parking fees

    • Garage rent

    • Depreciation

  • Unreimbursed Mileage. As with the standard mileage rate method, only unreimbursed business mileage can be claimed.

Important note: If you choose the actual expense method in the first year, you must stick with it for that vehicle in all subsequent years.

Actual Expenses Method Example

For 2023, your annual vehicle expenses were $7,500 including:

  • Lease payments: $4,000

  • Gas and oil: $1,800

  • Repairs: $900

  • Tires: $300

  • Insurance: $500

You drove a total of 50,000 miles with 25,000 for business purposes.

To determine your business mileage percentage, divide your business miles by your total mileage:

25,000 business miles / 50,000 total miles = 50%

Now, calculate the deduction by multiplying your business mileage percentage by your total car expenses:

50% X $7,500 = $3,750

Under the actual expense method, you can claim $3,750 for the business mileage deduction.

How Do You Decide Which Method to Use?

Selecting the appropriate method for tracking your mileage deductions depends on your individual circumstances. Factors to consider include:

  • Simplicity vs Documentation. The standard mileage rate method is a great choice for those who prefer a simplified process and don't want to deal with extensive record-keeping. On the other hand, the actual expense method requires meticulous documentation but can lead to more substantial deductions on your tax return.

  • Vehicle Operating Costs. If you drive a vehicle with relatively low operating costs and few business-related expenses, the standard mileage rate method may be the better option. However, if your vehicle comes with high expenses, such as repairs, maintenance, and lease payments, the actual expense method could potentially result in higher deductions.

  • Record-Keeping Abilities. Consider your record-keeping abilities and the time you're willing to invest. The actual expense method demands diligent documentation, while the standard mileage rate method relies on simpler mileage logs.

The IRS May Want to See Your Records

Regardless of the method you choose, the IRS may request your mileage records as part of a tax audit. One of the top IRS audit triggers is irregular business mileage deductions, e.g. claiming 100% business mileage. Therefore, it's crucial to maintain accurate records and documentation, such as a mileage log of all business miles driven along with all vehicle-related expense receipts.

How Do You Keep a Mileage Log?

Maintaining a mileage log is a fundamental part of claiming mileage deductions no matter which deduction method you choose. Follow these steps to keep an organized mileage log:

  1. Choose a Format. Decide whether you'll keep a physical mileage log or use an app to track mileage automatically.

  2. Include Essential Details. For each trip, record the date, destination, purpose (e.g., client meeting, business errands), odometer readings, and the number of miles driven.

  3. Regular Updates. Make a habit of updating your mileage log promptly after each trip to ensure accuracy.

  4. Preserve Supporting Documentation. Keep receipts and records of expenses related to your vehicle. This documentation can serve as evidence if your deductions are audited.

  5. Backup and Security. If using an app, regularly back up your mileage data and ensure it's secure.

  6. Consult a Tax Professional. If you have questions about your mileage deductions, consider hiring a tax professional. They can provide valuable guidance and help ensure you're following IRS regulations.

Rev Up Your Tax Savings With Mileage Deductions

Taking potential tax savings through mileage deductions requires a clear understanding of the rules, methods, and eligibility criteria. By carefully tracking your business-related travel and staying informed about the latest tax regulations, you can make the most of this valuable tax benefit.

Remember that this guide serves as an informative resource, but for personalized tax advice and guidance, it's always a wise decision to consult with a qualified tax professional. They will be able to evaluate your specific situation and help you determine which method would be the best fit for you.
