In 2013, the IRS issued regulations clarifying when tangible real and personal business property can be expensed. The regulations provided safe harbors that let you deduct certain costs you’d otherwise have to capitalize. For example, using a de minimis safe harbor, you could elect to deduct individual capital expenditures of $500 or less if your business did not have an “applicable financial statement.” (In general, an applicable financial statement is a financial statement based on a certified audit by an accounting firm.) Effective beginning with 2016 taxable years, this safe harbor has increased to $2,500 per invoice or item. In addition, the IRS says it will not contest similar treatment in audits of earlier years.
