For those claiming actual expenses rather than using the standard mileage rate, the Annual depreciation and expensing deductions for so-called luxury autos are limited to specific dollar amounts. These amounts are inflation-adjusted each year. The IRS has announced that for autos (not trucks or vans) first placed in service during 2017, the dollar limit for the first year an auto is in service is $3,160 ($11,160 if the bonus first-year depreciation allowance applies); for the second tax year, $5,100; for the third tax year, $3,050; and for each succeeding year, $1,875. These dollar limits are the same as those that applied for autos first placed in service in 2016.
For light trucks or vans (passenger autos built on a truck chassis, including minivan and sport-utility vehicles (SUVs) built on a truck chassis) first placed in service during 2017, the dollar limit for the first year the vehicle is in service is $3,560 ($11,560 if the bonus first-year depreciation allowance applies); for the second tax year, $5,700; for the third tax year, $3,450; and for each succeeding year, $2,075. For a light truck or van placed in service in 2017, the dollar figures are the same as for such vehicles first placed in service in 2016, except that the third-year amount is $100 higher.
A taxpayer that leases a business auto may deduct the part of the lease payment representing its business/investment use. If business/investment use is 100%, the full lease cost is deductible. So that auto lessees can't avoid the effect of the luxury auto limits, however, taxpayers must include a certain amount in income during each year of the lease to partially offset the lease deduction. The amount varies with the initial fair market value of the leased auto and the year of the lease, and is adjusted for inflation each year. The IRS has released a new inclusion amount table for autos first leased during 2017.
