Understanding Mileage Deductions

Mileage deductions allow you to reduce your taxable income based on the miles you drive for business purposes. The IRS offers two methods to calculate this deduction:

• Standard Mileage Rate: A fixed rate per mile driven for business.

• Actual Expense Method: Deducting the actual costs of operating your vehicle, including gas, maintenance, and depreciation.

  
  

Most individuals find the standard mileage rate easier to use, but the actual expense method can yield a larger deduction if your vehicle expenses are high.

What Counts as Deductible Mileage?

Only miles driven for business purposes qualify. This includes:

• Traveling to meet clients or customers.

• Driving between job sites.

• Going to the bank or post office for business needs.

• Attending business-related conferences or meetings.

  
  

Commuting miles, or the distance from your home to your regular workplace, are not deductible.

How to Track Mileage Correctly

Accurate mileage tracking is essential. The IRS requires detailed records to support your deduction claims. Here’s how to keep proper records:

• Use a mileage logbook or app: Record the date, starting point, destination, purpose of the trip, and miles driven.

• Record trips immediately: Don’t wait until the end of the week or month to log your miles.

• Keep receipts and supporting documents: For actual expense deductions, keep fuel, maintenance, and repair receipts.

• Separate personal and business use: If you use your vehicle for both, track business miles separately.

  
  

Example of a Mileage Log Entry

| Date | Starting Point | Destination | Purpose | Miles Driven |

|------------|----------------|-----------------|----------------------|-------------|

| 2024-03-15 | Home | Client Office | Client meeting | 12 |

| 2024-03-16 | Office | Supply Store | Purchase supplies | 8 |

Choosing the Right Deduction Method

Standard Mileage Rate

For 2024, the IRS standard mileage rate is 65.5 cents per mile. This rate covers gas, maintenance, insurance, and depreciation. Use this method if:

• You drive a newer vehicle with low expenses.

• You want a simple way to calculate deductions.

• You don’t have detailed records of actual expenses.

  
  

Actual Expense Method

This method requires tracking all vehicle-related expenses, including:

• Gasoline

• Oil changes

• Repairs

• Tires

• Insurance

• Registration fees

• Depreciation

  
  

Calculate the percentage of business use by dividing business miles by total miles driven. Multiply this percentage by your total vehicle expenses to find your deductible amount.

Switching Methods

You can switch between methods from year to year, but if you use the actual expense method and claim depreciation, you must stick with it for that vehicle.

Common Mistakes to Avoid

• Not keeping a mileage log: Without records, the IRS may disallow your deduction.

• Mixing personal and business miles: Only business miles count.

• Claiming commuting miles: These are not deductible.

• Overestimating miles: Be honest and accurate to avoid audits.

• Failing to update mileage rates: Use the IRS rate for the correct tax year.

  
  

Tools to Simplify Mileage Tracking

Technology makes mileage tracking easier and more accurate. Consider these options:

• Mileage tracking apps: Apps like MileIQ, Everlance, or Stride automatically track and categorize trips.

• Spreadsheet templates: For those who prefer manual tracking, spreadsheets can organize mileage logs.

• Vehicle telematics: Some vehicles have built-in tracking systems that record mileage.

  
  

What to Do When Audited

If the IRS audits your mileage deduction, they will ask for your mileage logs and supporting documents. To prepare:

• Keep your mileage logs organized and up to date.

• Retain receipts for vehicle expenses if using the actual expense method.

• Be ready to explain the purpose of each trip.
