Section 179 of the IRS tax code gives businesses the opportunity to deduct the FULL purchase price of qualifying new and used equipment, and software placed into service during the tax year they were purchased or financed. This tax break encourages small businesses to invest in themselves and to purchase equipment sooner rather than later. There are some limits, however, to the amount that can be written off. Use this calculator to help determine your Section 179 write off amount and the tax savings it might generate for you.
