New Change Starting in 2018 Tax Year as per Publication 463:

Employees can no longer claim the cost of using their car as unreimbursed employee travel expenses as a miscellaneous itemized deduction. Therefore, you can no longer deduct unreimbursed business use expenses of your car if you are an employee that used your car for work. This is because of the suspension of miscellaneous itemized deductions that are subject to the 2% floor detailed in section 67 of publication 463. The suspension applies to tax years beginning after Dec 2017. Deductions for expenses that are deductible in determining adjusted gross income are not suspended. This applies to the employee whether they use the standard rate tax deduction method of the actual car expense method. However, this does not apply to freelancers and independents.

The Standard Mileage Rate Method

The standard mileage rate is a method of deducting an IRS-established per mile tax-deductible dollar amount. The established per mile amount is only deductible for mileage driven for business purposes. Further, this method can only be used by the owner or lessor of the vehicle. For 2019, the standard mileage rate method is $0.58 per mile.

For an up-to-date list of the standard mileage rate deductions bookmark our post, IRS Standard Mileage Rate Tax Deductions.

To use this method the taxpayer must keep a record or log of the miles traveled for business. This includes information such as the destination and business purpose (IRS Publication 463, Ch 5, Recordkeeping). In addition, the taxpayer must document proof of ownership of the vehicle or a lease. Further, this information is added to the individuals’ tax return at the end of the year using IRS Form 2106. Also, business-related parking and tolls expenses are tax-deductible mileage expenses under the standard mileage rate deduction method.

The Standard Mileage Rate cannot be used if the taxpayer …

  • Uses the car for hire (such as a taxi)
  • Uses five or more cars at the same time (as in a fleet operation)
  • Claims depreciation or a section 179 deduction (Publication 463, Chapter 4)
  • If a rural mail carrier receives a qualified reimbursement (Publication 463, Chapter 4).

The required information for a Standard Rate Mileage method mileage report:

  • the miles you drove for business (ie your mileage) 
  • the places you drove for business 
  • the business purpose of your trip
  • the date of your trip

What qualifies for IRS mileage reimbursement?

To qualify for IRS mileage reimbursement you need to drive for business and record the miles you drove for business as specified by the IRS under the Standard Mileage Rate Expense method.

The Actual Car Expense Method

The actual car expense method allows taxpayers to deduct the following vehicle and vehicle-related expenses:

  • Depreciation
  • Lease payments
  • Registration fees
  • Licenses
  • Gas
  • Insurance
  • Repairs
  • Oil
  • Garage rent
  • Tires
  • Tolls
  • Parking fees

If the business use of the car is less than 100%, expenses must be proportionally allocated between business and personal use. For example, say you drive your car 20,000 miles in one year–10,000 for business and 10,000 for personal. In this case, the taxpayer can only deduct 50% of the vehicle’s expenses from their tax return. Therefore, in the cases of mixed personal and business use of the car, it is recommended that the taxpayer keep a log of the miles traveled and distinguish the business from personal travel. This will facilitate ease in the determination and calculation of the percentage of vehicle usage for business purposes. In addition, the taxpayer should keep receipts and invoices of vehicle expenses. Taxpayers that use the Actual Car Expense method can use IRS form 2106-EZ, Unreimbursed Employee Business Expenses, to claim these expenses on their tax return. Download this form, here.

Whether you should use the standard mileage rate or depends on your vehicle and the amount that you drive your vehicle for work. With strong record-keeping calculating the deductions for both methods can help the taxpayer determine which method will maximize their tax return. Both methods require the taxpayer to keep a mileage log.
