Vehicle Deductions for the Self-Employed: Standard Mileage vs. Actual Expenses Explained

If you’re self-employed and using a vehicle for your business, the IRS gives you two ways to deduct those costs.

But there are rules, and the decision you make the first year the vehicle is placed in service matters more than most people realize.

Let’s break it down.

First: This Does Not Apply to W-2 Employees

If you receive a W-2 paycheck, vehicle reimbursements are handled between you and your employer. Those rules are completely separate.

This blog applies only to:

• Self-employed individuals

• Schedule C filers

• Business owners with entities filing separate tax returns

You Must Track Mileage, No Matter What

Regardless of which deduction method you choose, you must track:

• Total annual miles

• Business miles

• Personal miles

The IRS requires us to calculate the business-use percentage every year.

If your vehicle is used less than 50% for business, certain deductions become limited.

Good habit: use an app like MileIQ or Quickbooks, or keep a notebook in your glovebox to record odometer readings at the beginning and end of the year. Consistency matters more than perfection.

Your Two Deduction Options

Option 1: Actual Expenses Method

With this method, you deduct:

• Depreciation (usually over 5 years)

• Possible bonus depreciation (if available that tax year)

• Gas

• Repairs and maintenance

• Insurance

• Registration and plates

• Tires, oil changes, etc.

Everything is multiplied by your business-use percentage.

This requires detailed recordkeeping and a worksheet reconciling costs to your tax return.

Important note: You can switch from standard mileage to actual expenses later. You generally cannot switch from actual expenses back to mileage.

So the first-year decision is strategic.

Option 2: Standard Mileage Rate

The IRS sets a rate each year. For 2025, it’s 70 cents per business mile.

This rate already factors in:

• Depreciation

• Fuel

• Maintenance

• Repairs

You simply multiply business miles by the IRS rate.

This method:

• Simplifies recordkeeping

• Often works well for newer vehicles

• Requires fewer receipts

When Title and Ownership Matter

If your business files a separate tax return (LLC, S-Corp, etc.):

• To claim actual expenses, the vehicle must be titled in the business’s name.

• Otherwise, you may need an accountable plan to reimburse yourself.

This is where proper planning prevents problems later.

What You Cannot Deduct

Commuting is never deductible.

Driving from your home to your regular workplace and from your workplace back home is considered personal use — even if you’re self-employed.

However, if you qualify for a legitimate home office (used 100% exclusively for business), that can change how mileage is treated. And “exclusive” truly means exclusive. Not part-time. Not shared. Not occasional.

Special Situations

If you’re in either of these situations, you need strategic guidance:

• You can make a one-time change from mileage to actual expenses.

• If you operate more than five vehicles as a fleet, standard mileage is not allowed.

The Bigger Picture For Vehicle Tax Deductions

Vehicle deductions seem straightforward.

But the method you choose affects:

• Depreciation timing

• Long-term tax strategy

• Audit risk

• Retirement income projections
