Section 179 Tax Deduction for Commercial Buildings

Section 179 Tax Deduction for Commercial Buildings

Are you thinking about investing money into your business? You couldn’t have picked a better time!

A recent change to the Section 179 Deduction, under the Tax Cuts and Jobs Act, has increased the amount of money that taxpayers are allowed to deduct (up to $1 million) on their income taxes as an expense, rather than requiring the cost of the property to be capitalized and depreciated.

As of Jan. 1, 2019, the Tax Cuts and Jobs Act has expanded the definition of qualified property that is eligible for expensing under Section 179 Tax Deduction; this includes improvements to commercial roofing.

Section 179 Explained

It may seem daunting when you start looking into tax law, but Section 179 is not as complicated as it may seem. Section 179 of the IRS Tax Code allows a business to deduct, for the current tax year, the full purchase price of equipment and off-the-shelf software that qualifies for the deduction.

Simply put, the US government wants businesses to invest in themselves, so if you purchase something for your business that qualifies, you can deduct the full price of that business purchase on your taxes of that same calendar year.

What Qualifies?

The Section 179 Tax Deduction covers business supplies, upgrades, improvements, and property that is purchased or leased in the same calendar year. Since the deduction was created with all businesses in mind, the list includes purchases that many companies need.

The list of qualifying purchases includes, but is not limited to:

  • Certain improvements to existing non-residential buildings: roofing, fire suppression, alarms and security systems, and HVAC.
  • Equipment (machines, etc.) purchased for business use
  • Business Vehicles with a gross vehicle weight more than 6,000
  • Computers and “Off-the-Shelf” Software
  • Office Furniture and Equipment
  • Property attached to your building that is not a structural component of the building (e., a printing press, large manufacturing tools, and equipment)



There are a few limitations to consider with the Section 179 tax deduction:

  1. Dollar Amount – The dollar limitation has changed over the years, but after the most recent update (as of July 2019) the dollar limit is $1 million.

  1. To qualify for the Section 179 deduction for any given tax year, the equipment must be purchased (or financed/leased) and placed into service between January 1 and December 31 of that year.

  1. If a taxpayer places more than $2 million worth of Section 179 property into service during a single taxable year, the Section 179 deduction is reduced, by the amount exceeding the threshold.

  1. The amount allowed as a deduction can’t exceed the aggregate amount of taxable income for the business during that year.
