Section 179 for 2018


Section 179 is an incentive created by the U.S. government to spur businesses into buying equipment and investing in themselves by way of a depreciation deduction that allows them to deduct the cost of qualifying tangible goods as an expense, rather than requiring the cost to be capitalized and depreciated.

Section 179 Tax Deduction for 2018

Section 179 of the U.S. tax code allows businesses to deduct the full price of qualifying equipment or off-the-shelf software purchased, financed or leased during the 2018 tax year from their gross income.


2018 Deduction Cap: $1,000,000

This deduction is good on new or used equipment, in addition to off-the-shelf software. To take the deduction for tax year 2018, equipment must be financed or purchased (or leased) and put into service between January 1, 2018 and the end of December 31, 2018.

2018 Limit on Equipment Purchases: $2,500,000

This is the maximum amount that can be spent on equipment before the Section 179 Deduction available to your company begins to be reduced on a dollar for dollar basis. This spending cap makes Section 179 a true “small business tax incentive” (because larger businesses that spend more than $3.5 million on equipment won’t get the deduction.)

2018 Bonus Depreciation: 100%

Bonus Depreciation is ordinarily taken after the Section 179 Spending Cap is reached and is available for both new and used equipment.
