The Tax Cuts and Jobs Act (TCJA) made changes that impact the depreciation and expensing of vehicles.

2018 Depreciation Limitations On Luxury Automobiles And Personal Use Property
For passenger automobiles placed into service after December 31, 2017, SECTION 13202 of the Tax Cuts And Jobs Act increases the dollar limitations on depreciation and expensing for passenger automobiles. For 2018, the amount of the depreciation and expensing deduction for a passenger car, light duty truck or van shall not exceed--

• $10,000 for the 1st taxable year in the recovery period,
• $16,000 for the 2nd taxable year in the recovery period,
• $9,600 for the 3rd taxable year in the recovery period, and
• $5,760 for each succeeding taxable year in the recovery period.

These numbers shall be adjusted for inflation after 2018. As such, for 2018, the limits for light-duty trucks, vans, and passenger cars are the same.
The TCJA retained the $8,000 limit for additional first-year depreciation for passenger automobiles. So in 2018, the maximum amount a taxpayer can deduct for a passenger automobile in the first year is $18,000.

Larger Vehicles
The TCJA increased bonus depreciation to 100 percent for qualifying property acquired and placed into service after September 27, 2017, and before January 1, 2023. It also extended bonus depreciation to used property acquired and placed into service after September 27, 2017.
SUVs with a gross vehicle weight rating above 6,000 lbs. are not subject to depreciation limits. They are, however, limited to a $25,000 IRC §179 deduction. IRC § 179(b)(5)(A). No depreciation or §179 limits apply to SUVs with a GVW more than 14,000 lbs. Trucks and vans with a GVW rating above 6,000 lbs. but not more than 14,000 lbs. generally have the same limits: no depreciation limitation, but a $25,000 IRC §179 deduction. These vehicles, however, are not subject to the §179 $25,000 limit if any of the following exceptions apply:

• -The vehicle is designed to have a seating capacity of more than nine persons behind the driver’s seat;
• -The vehicle is equipped with a cargo area at least 6 feet in interior length that is an open area or is designed for use as an open area but is enclosed by a cap and is not readily accessible directly from the passenger compartment; or
• -The vehicle has an integral enclosure, fully enclosing the driver compartment and load-carrying device, does not have seating behind the driver’s seat, and has no body section protruding more than 30 inches ahead of the leading edge of the windshield.

Although SUVs purchased after September 27, 2017, remain subject to the $25,000 IRC § 179 limit, they are eligible for 100% bonus depreciation if they are above 6,000 lbs. This is true for both new and used vehicles. For a taxpayer’s first taxable year ending after Sept. 27, 2017, taxpayers may elect to apply a 50 percent allowance instead of the 100 percent allowance. To make the election, they must attach a statement to a timely filed return (including extensions) indicating they are electing to claim a 50% special depreciation allowance for all qualified property. Once made, the election cannot be revoked without IRS consent. As noted above, taxpayers may also elect out of bonus entirely for any class of property by filing an election on a timely filed return. Once filed, that election can also not be revoked without IRS consent.

Business Use Of Car
If you use your car in your job or business and you use it only for that purpose, you may deduct its entire cost of operation (subject to limits). However, if you use the car for both business and personal purposes, you may deduct only the cost of its business use.
You can generally figure the amount of your deductible car expense by using one of two methods: the standard mileage rate method or the actual expense method. If you qualify to use both methods, you may want to figure your deduction both ways before choosing a method to see which one gives you a larger deduction.
Standard Mileage Rate – The Internal Revenue Service issued the 2018 optional standard mileage rates used to calculate the deductible costs of operating an automobile for business, charitable, medical or moving purposes.
Beginning on Jan. 1, 2018, the standard mileage rates for the use of a car (also vans, pickups or panel trucks) will be:

• 54.5 cents for every mile of business travel driven, up 1 cent from the rate for 2017.
• 18 cents per mile driven for medical or moving purposes, up 1 cent from the rate for 2017.
• 14 cents per mile driven in service of charitable organizations.

The business mileage rate and the medical and moving expense rates each increased 1 cent per mile from the rates for 2017. The charitable rate is set by statute and remains unchanged.
The standard mileage rate for business is based on an annual study of the fixed and variable costs of operating an automobile. The rate for medical and moving purposes is based on the variable costs.
Taxpayers always have the option of calculating the actual costs of using their vehicle rather than using the standard mileage rates.
A taxpayer may not use the business standard mileage rate for a vehicle after using any depreciation method under the Modified Accelerated Cost Recovery System (MACRS) or after claiming a Section 179 deduction for that vehicle. In addition, the business standard mileage rate cannot be used for more than four vehicles used simultaneously.
Use of Standard Mileage Rates
To use the standard mileage rate, you must own or lease the car and:

• You must not operate five or more cars at the same time, as in a fleet operation,
• You must not have claimed a depreciation deduction for the car using any method other than straight-line,
• You must not have claimed a Section 179 deduction on the car,
• You must not have claimed the special depreciation allowance on the car,
• You must not have claimed actual expenses after 1997 for a car you lease, and
• You can’t be a rural mail carrier who received a “qualified reimbursement.”

To use the standard mileage rate for a car you own, you must choose to use it in the first year the car is available for use in your business. Then, in later years, you can choose to use the standard mileage rate or actual expenses.
For a car you lease, you must use the standard mileage rate method for the entire lease period (including renewals) if 
you choose the standard mileage rate.
Actual Expenses – To use the actual expense method, you must determine what it actually costs to operate the car for the portion of the overall use of the car that’s business use. Include gas, oil, repairs, tires, insurance, registration fees, licenses, and depreciation (or lease payments) attributable to the portion of the total miles driven that are business miles.
Note: Other car expenses for parking fees and tolls attributable to business use are separately deductible, whether you use the standard mileage rate or actual expenses.
Depreciation                 
Generally, the Modified Accelerated Cost Recovery System (MACRS) is the only depreciation method that can be used by car owners to depreciate any car placed in service after 1986. However, if you used the standard mileage rate in the year you place the car in service and change to the actual expense method in a later year and before your car is fully depreciated, you must use straight-line depreciation over the estimated remaining useful life of the car.
Recordkeeping
The law requires that you substantiate your expenses by adequate records or by sufficient evidence to support your own statement.

​Lower Tax Rates and Changed Income Ranges
The bill retains the seven tax brackets found in current law but lowers a number of the tax rates. It also changes the income thresholds at which the rates apply.
The current brackets are: 10%, 15%, 25%, 28%, 33%, 35% and 39.6%
The new brackets will be: 10%, 12%, 22%, 24%, 32%, 35% and 37%
The income thresholds at which these brackets kick in have changed, as well.

​For single filers:
Alternative Minimum Tax Exemptions Increased
The bill also eases the burden of the individual alternative minimum tax (AMT) by raising the income exempted from $84,500 (adjusted for inflation) to $109,400 married filing jointly and from $54,300 (adjusted for inflation) to $70,300 for single taxpayers, so fewer taxpayers will pay it.
Tax Relief for Individuals and Families
Increased standard deduction:
The new tax law nearly doubles the standard deduction amount. Single taxpayers will see their standard deductions jump from $6,350 for 2017 taxes to $12,000 for 2018 taxes (the ones you file in 2019).
Married couples filing jointly see an increase from $12,700 to $24,000. These increases mean that fewer people will have to itemize. Today, roughly 30% of taxpayers itemize. Under the new law, this percentage is expected to decrease.
Increased Child Tax Credit:
For, families with children the Child Tax Credit is doubled from $1,000 per child to $2,000. In addition, the amount that is refundable grows from $1,100 to $1,400. The bill also adds a new, non-refundable credit of $500 for dependents other than children. Finally, it raises the income threshold at which these benefits phase out from $110,000 for a married couple to $400,000.
 
Eliminations or Reductions in Deductions
Personal and dependent exemptions:
The bill eliminates the personal and dependent exemptions which are currently $4,050 for 2017 and were expected to increase to $4,150 in 2018.
State and local taxes/Home mortgages:
The bill limits the amount of state and local property, income, and sales taxes that can be deducted to $10,000. In the past, these taxes have generally been fully tax deductible.
The bill also caps the amount of mortgage indebtedness on new home purchases on which interest can be deducted at $750,000 down from $1,000,000 in current law.
Health care:
The bill eliminates the tax penalty for not having health insurance after December 31, 2018. It also temporarily lowers the floor above which out-of-pocket medical expenses can be deducted from the current law floor of 10% to 7.5% for 2017 and 2018
So for 2017 and 2018, you can deduct medical expenses that are more than 7.5% of your adjusted gross income as opposed to the higher 10%.
Self-employed (contractors, freelancers, sole proprietors) and small businesses:
The bill has a myriad of changes for business. The biggest includes a reduction in the top corporate rate to 21%, a new 20% deduction for incomes from certain type of “pass-through” entities (partnerships, S Corps, sole proprietorships), limits on expensing of interest from borrowing, almost doubling of the amount small businesses can expense from the 2017 Section 179 amount of $510,000 to $1,000,000, and eliminates the corporate alternative minimum tax (AMT).
