Individuals can deduct some vehicle-related expenses in certain
circumstances. Rather than keeping track of the actual costs, you can use a
standard mileage rate to compute your deductions. For 2017, you might be able
to deduct miles driven for business, medical, moving and charitable purposes.
For 2018, there are significant changes to some of these deductions under the
Tax Cuts and Jobs Act (TCJA).
Mileage rates vary
The rates vary depending on the purpose and the year:
Business: 53.5 cents (2017), 54.5 cents (2018)
Medical: 17 cents (2017), 18 cents (2018)
Moving: 17 cents (2017), 18 cents (2018)
Charitable: 14 cents (2017 and 2018)
The business standard mileage rate is considerably higher than
the medical, moving and charitable rates because the business rate contains a
depreciation component. No depreciation is allowed for the medical, moving or
charitable use of a vehicle. The charitable rate is lower than the medical and
moving rate because it isn’t adjusted for inflation.
In addition to deductions based on the standard mileage rate,
you may deduct related parking fees and tolls.
2017 and 2018 limits
The rules surrounding the various mileage deductions are
complex. Some are subject to floors and some require you to meet specific tests
in order to qualify.
For example, if you’re an employee, only business mileage not
reimbursed by your employer is deductible. It’s a miscellaneous itemized
deduction subject to a 2% of adjusted gross income (AGI) floor. For 2017, this
means mileage is deductible only to the extent that your total miscellaneous
itemized deductions for the year exceed 2% of your AGI. For 2018, it means that
you can’t deduct the mileage, because the TCJA suspends miscellaneous itemized
deductions subject to the 2% floor for 2018 through 2025.
If you’re self-employed, business mileage can be deducted
against self-employment income. Therefore, it’s not subject to the 2% floor and
is still deductible for 2018 through 2025, as long as it otherwise qualifies.
Miles driven for health-care-related purposes are deductible as
part of the medical expense deduction. And an AGI floor applies. Under the TCJA,
for 2017 and 2018, medical expenses are deductible to the extent they exceed
7.5% of your adjusted gross income. For 2019, the floor will return to 10%,
unless Congress extends the 7.5% floor.
And while miles driven related to moving can be deductible on
your 2017 return, the move must be work-related and meet other tests. For 2018
through 2025, under the TCJA, moving expenses are deductible only for certain
military families.
Substantiation and more
There are also substantiation requirements, which include
tracking miles driven. And, in some cases, you might be better off deducting
actual expenses rather than using the mileage rates.
We can help ensure you deduct all the mileage you’re entitled to
on your 2017 tax return but don’t risk back taxes and penalties later for
deducting more
than allowed. Contact us for assistance and to learn how your mileage deduction
for 2018 might be affected by the TCJA.
