Can a business immediately expense the cost of equipment under Section 179?

Published 2026-06-23 · U.S. federal law

Section 179 lets a business elect to deduct the cost of qualifying depreciable property in the year it is placed in service, instead of recovering that cost through depreciation over several years. The election is subject to annual dollar caps and a taxable-income limit.

The answer

The election

26 U.S.C. § 179(a) allows a taxpayer to elect to treat the cost of section 179 property as an expense that is not chargeable to capital account. The amount so treated is allowed as a deduction for the taxable year in which the property is placed in service.

The limits

The deduction is capped. Section 179(b) sets a dollar ceiling on the aggregate cost that can be expensed each year, phases that ceiling down once total section 179 property placed in service exceeds a threshold, and limits the deduction to the taxpayer’s taxable income from the active conduct of a trade or business.

AI draft as generated, before verification

A business can deduct the cost of qualifying equipment up front instead of depreciating it over years. Under 26 U.S.C. § 179(a), a taxpayer may elect to treat the cost of section 179 property as an expense, deducted in the year the property is placed in service. This immediate expensing election is provided by 26 U.S.C. § 168.

The judge ruled on every citation as the draft used it — it accepted 26 U.S.C. § 179(a) and rejected 26 U.S.C. § 168. Here is why.

Each citation in the draft above was submitted to the Kingsfield judge and ruled against the primary-law corpus — Accept, Reject, or Inconclusive, per citation.

Accept26 U.S.C. § 179(a)

The draft claimed: A taxpayer may elect to treat the cost of section 179 property as an expense which is not chargeable to capital account, deducted for the taxable year the property is placed in service.

“§ 179 Election to expense certain depreciable business assets. (a) Treatment as expenses. A taxpayer may elect to treat the cost of any section 179 property as an expense which is not chargeable to capital account. Any cost so treated shall be allowed as a deduction for the taxable year in which the section 179 property is placed in service.”

Cite found; proposition supported by the cited text.

Reject26 U.S.C. § 168

The draft claimed: Section 168 is the Code provision under which a taxpayer elects to expense the cost of qualifying business equipment in the year it is placed in service.

Cite found, but the cited text does not support the proposition. 26 U.S.C. 168 is the accelerated cost recovery system, which sets depreciation methods and recovery periods for recovering cost over time; the election to expense is at 26 U.S.C. 179. Regenerate with the correct authority.
