Section 179 was designed with businesses in mind. That's why almost all types of "business equipment" that your company buys or finances qualifies for the Section 179 deduction.
All businesses need equipment on an ongoing basis, be it machinery, computers, software, office furniture, vehicles, or other tangible goods. It's very likely that your business will purchase many of these goods during the year, and will do so again and again. Section 179 is designed to make purchasing that equipment during this calendar year financially attractive.
