The Section 179 tax deduction for 2017, is set at $500,000 this year. Instead of deducting equipment or software over time – according to a set depreciation schedule – Section 179 of the tax code allows many businesses to deduct the full purchase price the first tax year.
It works for leased or purchased equipment. When you purchase you pay the entire amount for the equipment out of pocket, and then deduct the purchase price on your taxes. When you lease  you pay only the monthly lease payments out of pocket, and still get to deduct the full purchase price on your taxes.
Whether you choose to purchase or lease equipment/software under Section 179 you’ll need to put it into service by the end of the day 12/31/2017.
