Most people think the Section 179 deduction is some mysterious or complicated tax code. It really isn't, as you will see below.
Essentially, Section 179 of the IRS tax code allows businesses to deduct the full purchase price of qualifying equipment and/or software purchased or financed during the tax year. That means that if you buy (or lease) a piece of qualifying equipment, you can deduct the FULL PURCHASE PRICE from your gross income. It's an incentive created by the U.S. government to encourage businesses to buy equipment and invest in themselves.
Several years ago, Section 179 was often referred to as the "SUV Tax Loophole" or the "Hummer Deduction" because many businesses have used this tax code to write-off the purchase of qualifying vehicles at the time (like SUV's and Hummers). But, that particular benefit of Section 179 has been severely reduced in recent years, see 'Vehicles & Section 179' for current limits on business vehicles.
Today, Section 179 is one of the few incentives included in any of the recent Stimulus Bills that actually helps small businesses. Although large businesses also benefit from Section 179 or Bonus Depreciation, the original target of this legislation was much needed tax relief for small businesses - and millions of small businesses are actually taking action and getting real benefits.
