Deduction of Vehicle Expenses for Individual Taxpayers

It’s not just businesses that can deduct vehicle-related expenses. Individuals also can deduct them in certain circumstances. Unfortunately, the Tax Cuts and Jobs Act (TCJA) might reduce your deduction compared to what you claimed on your 2017 return.

For 2017, miles driven for business, moving, medical and charitable purposes were potentially deductible. For 2018 through 2025, business and moving miles are deductible only in much more limited circumstances. TCJA changes could also affect your tax benefit from medical and charitable miles.

Current limits vs. 2017

Before 2018, if you were an employee, you potentially could deduct business mileage not reimbursed by your employer as a miscellaneous itemized deduction. But the deduction was subject to a 2% of adjusted gross income (AGI) floor, which meant that mileage was deductible only to the extent that your total miscellaneous itemized deductions for the year exceeded 2% of your AGI. For 2018 through 2025, you can’t deduct the mileage regardless of your AGI. Why? The TCJA suspends miscellaneous itemized deductions subject to the 2% floor.

If you’re self-employed, business mileage is deducted from 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 a work-related move in 2017 were generally deductible “above the line” (that is, itemizing isn’t required to claim the deduction). But for 2018 through 2025, under the TCJA, moving expenses are deductible only for certain military families.

Miles driven for health-care-related purposes are deductible as part of the medical expense itemized deduction. Under the TCJA, for 2017 and 2018, medical expenses are deductible to the extent they exceed 7.5% of your AGI. For 2019, the floor returns to 10%, unless Congress extends the 7.5% floor.

The limits for deducting expenses for charitable miles driven haven’t changed, but keep in mind that it’s an itemized deduction. So, you can claim the deduction only if you itemize. For 2018 through 2025, the standard deduction has been nearly doubled. Depending on your total itemized deductions, you might be better off claiming the standard deduction, in which case you’ll get no tax benefit from your charitable miles (or from your medical miles, even if you exceed the AGI floor).

Differing mileage rates

Rather than keeping track of your actual vehicle expenses, you can use a standard mileage rate to compute your deductions. The rates vary depending on the purpose and the year:

  • Business: 54.5 cents (2018), 58 cents (2019)
  • Medical: 18 cents (2018), 20 cents (2019)
  • Moving: 18 cents (2018), 20 cents (2019)
  • Charitable: 14 cents (2018 and 2019)

In addition to deductions based on the standard mileage rate, you may deduct related parking fees and tolls. There are also substantiation requirements, which include tracking miles driven.

Two Major Tax Law Changes for Individuals in 2019

Medical expense deduction threshold

With rising health care costs, claiming whatever tax breaks related to health care that you can is more important than ever. But there’s a threshold for deducting medical expenses that was already difficult for many taxpayers to meet, and it may be even harder to meet this year.

The TCJA temporarily reduced the threshold from 10% of adjusted gross income (AGI) to 7.5% of AGI. Unfortunately, the reduction applies only to 2017 and 2018. So for 2019, the threshold returns to 10% — unless legislation is signed into law extending the 7.5% threshold. Only qualified, unreimbursed expenses exceeding the threshold can be deducted.

Also, keep in mind that you have to itemize deductions to deduct medical expenses. Itemizing saves tax only if your total itemized deductions exceed your standard deduction. And with the TCJA’s near doubling of the standard deduction for 2018 through 2025, many taxpayers who’ve typically itemized may no longer benefit from itemizing.

Tax treatment of alimony

Alimony has generally been deductible by the ex-spouse paying it and included in the taxable income of the ex-spouse receiving it. Child support, on the other hand, hasn’t been deductible by the payer or taxable income to the recipient.

Under the TCJA, for divorce agreements executed (or, in some cases, modified) after December 31, 2018, alimony payments won’t be deductible — and will be excluded from the recipient’s taxable income. So, essentially, alimony will be treated the same way as child support.

Because the recipient ex-spouse would typically pay income taxes at a rate lower than that of the paying ex-spouse, the overall tax bite will likely be larger under this new tax treatment. This change is permanent.

TCJA impact on 2018 and 2019
