Understanding the 2020 Standard Mileage Rates
For the 2020 tax year, the Internal Revenue Service (IRS) adjusted the optional standard mileage rates used to calculate the deductible costs of operating an automobile for business, charitable, medical, or moving purposes. This calculator uses the official rates set forth in IRS Notice 2020-05.
Key 2020 Rates at a Glance:
Business: 57.5 cents per mile (down from 58 cents in 2019).
Medical & Moving: 17 cents per mile (down from 20 cents in 2019).
Charitable: 14 cents per mile (unchanged by statute).
Who Can Use These Rates?
The standard mileage rate is an optional method for taxpayers to calculate the deductible costs of using a vehicle. Instead of tracking actual expenses (like gas, insurance, repairs, and depreciation), you can simply multiply your business miles by the standard rate of 57.5 cents.
Note that under the Tax Cuts and Jobs Act, taxpayers usually cannot claim a miscellaneous itemized deduction for unreimbursed employee travel expenses. However, self-employed individuals and certain other categories of taxpayers can still utilize these deductions.
Medical and Moving Mileage Explained
For 2020, the rate for medical care driving dropped to 17 cents per mile. This rate also applies to moving expenses, though the deduction for moving expenses is currently suspended for most taxpayers, with the exception of active-duty members of the Armed Forces moving under orders to a permanent change of station.
Documentation Requirements
To claim a mileage deduction on your 2020 tax return, the IRS requires timely and accurate records. Your log should include:
The date of the trip.
The starting point and destination.
The business purpose of the trip.
The total miles driven.
The total odometer reading at the start and end of the year.
While this calculator provides an estimate of your deduction value, always consult with a certified tax professional to ensure you meet all eligibility requirements for the 2020 tax year.
