Claim Mileage with the Actual Expense Method

As a self-employed professional or freelancer using your personal vehicle for business purposes, you have two options for claiming tax deductions on your vehicle expenses: the standard mileage rate or the actual expense method.

Standard mileage rate or actual expenses: How to get the biggest tax deduction? 

Standard Mileage Rate Method 

The standard mileage rate method is straightforward. With this approach, you simply multiply your business miles by the standard IRS mileage rate, which is adjusted annually to reflect the average vehicle ownership and operation costs. 

For example, if you drove 100 business miles and the current rate is $0.70 per mile, your deduction would be $70.

This flat rate accounts for car-related expenses like fuel, insurance, maintenance, and depreciation. Many choose this method for its simplicity.

Actual Expense Method

With the actual expense method, you track and deduct the actual costs of operating your vehicle for business instead of using the standardized rate. This method requires more diligent record-keeping but might result in larger deductions depending on how much (or little) you drive, your vehicle, and your expenses.

When using the actual expense method, you'll need to:

• Track all expenses related to your car throughout the year
• Calculate what percentage of your vehicle use was for business purposes
• Deduct that same percentage of your total car-related expenses

When to use the actual expense method?

Determining which mileage deduction method works best for you depends on several factors. The actual expense method might be more beneficial in certain scenarios, but it will also differ from year to year. If you drive a moderate amount for business purposes while incurring high vehicle-related expenses, you should consider using the actual expense method. 

The actual expense method typically benefits you most when:

• You own an expensive vehicle with substantial depreciation
• Your vehicle had significant repair costs during the tax year
• You pay high insurance premiums or finance charges
• Your business mileage is moderate rather than extremely high

The IRS recommends calculating your potential deduction using both methods and selecting the one that provides the greater tax benefit. This comparison is worth the extra effort, as the difference can be substantial depending on your circumstances. See IRS' Topic no. 510, Business use of car. 

Qualified expenses under the actual expense method

You can deduct a wide range of vehicle-related costs when using the actual expense method. These include:

• Gas
• Depreciation
• Repairs 
• Lease payments
• Registration and license fees
• Insurance
• Maintenance (such as oil changes)

But exclude car expenses for parking fees and tolls, attributable to business, which are separately deductible for self-employed, whether you use the standard mileage rate or actual expenses. Always maintain detailed records of all expenses throughout the year to substantiate your deductions if questioned by the IRS.

Record-keeping requirements 

Proper documentation is essential. The IRS requires you to retain relevant records for at least three years from the date you file your return. However, many tax professionals recommend keeping these records longer in case of delayed audits. For the actual expense method, records could include receipts and payment records for vehicle expenses as well as detailed mileage logs showing business vs. personal use.

Your mileage log should include each business trip's date, destination, purpose, and distance. These logs establish the business-use percentage of your vehicle, which directly affects the amount you can deduct. Many professionals find that using a mileage tracker app significantly simplifies this process. This way you can easily classify trips as business or personal and maintain detailed records of your driving patterns throughout the year, ensuring you have complete and accurate documentation when preparing your tax return.

Calculating your deduction

Determining your actual expense deduction involves three primary steps:

1. Add up all qualified vehicle expenses for the entire tax year
2. Calculate your business-use percentage by dividing business miles by total miles
3. Multiply your total expenses by the business-use percentage to find your deduction

This final figure represents the portion of your vehicle expenses attributable to business use, which is deductible on your tax return.

Example calculation:

Suppose you drove 5,000 business miles out of 10,000 total miles during the tax year, resulting in a 50% business-use percentage. Your vehicle expenses for the year included:

• Gas: $2,000
• Depreciation: $5,000
• Repairs: $1,000
• Registration and fees: $100
• Insurance: $1,500
• Maintenance: $500

Adding these expenses gives you a total of $10,100 in vehicle costs. Multiplying this amount by your 50% business-use percentage results in a deduction of $5,050 for the tax year.

Switching between actual expense and standard rate method 

The IRS allows some flexibility in choosing your deduction method from year to year, but important restrictions must be considered. 

Key points about switching methods:

• You can generally switch between methods from year to year to maximize your deduction
• If you use the actual expense method in the first year, you cannot switch to standard mileage later for that vehicle
• If you start with standard mileage, you can switch to actual expenses later (if you haven't fully depreciated the vehicle)
• The year you purchase a new vehicle requires careful consideration of which method to use initially

This flexibility allows you to adapt to changing circumstances, such as years with unusually high repair costs, when the actual expense method might be particularly advantageous.

Best practices for tracking business miles

Consistent and accurate mileage tracking forms the foundation of a successful actual expense deduction. Without reliable mileage records, you cannot determine your business-use percentage, which is essential for calculating your deduction.

Take time to evaluate both deduction methods based on your specific vehicle and business use patterns to ensure you're claiming the maximum allowable deduction. While the actual expense method isn't right for everyone, it can provide significant tax savings for those who meet the criteria outlined in this guide.

Remember to consult with a qualified tax professional about your specific situation, as tax laws and regulations may change, and individual circumstances vary. Proper planning and documentation allow you to maximize your vehicle expense deductions while remaining compliant with IRS requirements.
