Section 179
Section 179 of the IRS tax code allows businesses to write-off the full purchase price of qualifying piece of equipment -- such as machinery or technology hardware -- or computer software in the year it was purchased or financed. For example, if a business financed $100,000 worth of qualifying equipment during the 2022 tax year,, they can deduct the entire $60,000 from their 2020 taxable income.
Taxpayers, except trusts, estates and certain non-corporate lessors, can elect (on Form 4562) to expense the cost of qualifying property used in the active conduct of a trade or business. The portion of the cost not expensed under Sec 179 is depreciable. If the taxpayer’s use of the property drops to 50% or less in a subsequent year, recapture of some of the deduction benefit is required.
