Finally, lawmakers did the right thing by increasing the luxury auto depreciation limits on business cars. The old luxury limits were unrealistic, punitive, unfair, and discriminatory against any car that cost more than $15,800. The new limits don’t create parity in all respects, but they are a big improvement.
If you bought a car in 2017 and paid more than $15,800, you were driving a luxury car that lawmakers punished you for by putting a lid on your depreciation.
For example, say in 2017 you bought a $40,000 car and drove it 100 percent for business. Your maximum depreciation deductions for the first five years would total only $15,060. To fully depreciate this car under the old rules would have taken 19 years.
