Understanding the 2017 Standard Mileage Rates
If you are filing an amended tax return (Form 1040-X) for the 2017 tax year, or simply auditing your past records, it is critical to use the specific mileage rates assigned by the IRS for that calendar year. Using current year rates for past tax years will result in calculation errors and potential issues with the IRS.
For the tax year 2017, the Internal Revenue Service issued Notice 2016-79, which set the optional standard mileage rates used to calculate the deductible costs of operating an automobile for business, charitable, medical, or moving purposes. These rates applied to miles driven between January 1, 2017, and December 31, 2017.
Key 2017 Rates:
Business: 53.5 cents per mile (down from 54 cents in 2016).
Medical & Moving: 17 cents per mile (down from 19 cents in 2016).
Charitable Service: 14 cents per mile (statutory fixed rate).
How to Use This Calculator
This tool is specifically calibrated for 2017 returns. To calculate your deduction:
Review your 2017 Mileage Log: Sum up the total miles driven specifically for business purposes. Do not include commuting miles (driving from home to your regular place of work), as these were not deductible in 2017.
Enter Medical/Moving Miles: In 2017, you could deduct mileage for medical care or moving expenses if you met specific criteria (e.g., the distance test for moving). Enter these miles in the second field.
Enter Charitable Miles: If you drove your personal vehicle while volunteering for a qualified non-profit, enter those miles.
Add Parking & Tolls: While the standard mileage rate covers gas, insurance, and wear & tear, it does not cover parking fees and tolls. These can be added separately at 100% of the cost.
Business Mileage Eligibility in 2017
The business standard mileage rate of 53.5 cents was available for self-employed individuals and, at that time, certain employees with unreimbursed business expenses. Note that the Tax Cuts and Jobs Act of 2017 suspended the deduction for unreimbursed employee business expenses for tax years 2018 through 2025, but for the 2017 tax year, this deduction was still available under miscellaneous itemized deductions (subject to the 2% floor).
Why are 2017 rates lower than 2016?
You might notice the 2017 business rate (53.5 cents) is slightly lower than the 2016 rate (54 cents). The IRS adjusts these rates annually based on an in-depth study of the fixed and variable costs of operating an automobile. In 2017, lower fuel prices contributed to a slight reduction in the standard deduction rate compared to the previous year.
Record Keeping Requirements
To claim a mileage deduction on an amended 2017 return, you must have contemporaneous records. This means you should have a log created at or near the time of the trip containing:
The date of the trip.
The mileage driven (odometer readings are best).
The destination.
The business purpose of the trip.
Estimates are generally not accepted by the IRS during an audit. This calculator assumes your input numbers are backed by such records.
