Section 179 of the United States Internal Revenue Code provides a valuable tax incentive for businesses. It allows them to deduct the entire cost of qualifying equipment and software purchases in the year the assets are placed in service, rather than depreciating them over several years. This can significantly reduce a business's taxable income and tax liability in the short term, encouraging investment in equipment and technology. 

Key aspects of Section 179

• Eligibility: Generally, tangible personal property acquired for business use qualifies, including machinery, equipment, vehicles (subject to limitations), computers, and off-the-shelf software. Certain real property improvements, like roofs, HVAC, and security systems on non-residential buildings, also qualify.

• Deduction limits: The maximum deduction amount and investment phase-out thresholds are subject to annual inflation adjustments by the IRS. For 2024, the maximum Section 179 expense deduction is $1,220,000, and the deduction begins to phase out when the cost of qualifying property placed in service exceeds $3,050,000.

• Business use: The property must be used more than 50% for business purposes to qualify for the Section 179 deduction.

• Taxable income limitation: The Section 179 deduction cannot create or increase a net loss for the business. If the deduction exceeds the business's taxable income, the excess can be carried forward to future tax years.

• Election: Businesses must elect to take the Section 179 deduction by completing and filing Form 4562 with their tax return. 

Example

Imagine a small business purchases a new piece of qualifying machinery for $50,000 in 2025. Instead of depreciating the machine over its useful life (e.g., 5 or 7 years), the business can elect to deduct the full $50,000 in 2025 under Section 179, reducing its taxable income by that amount. This can lead to significant tax savings in the current year. 

Important considerations

• Section 179 is different from bonus depreciation. While both allow for accelerated depreciation, bonus depreciation is a percentage-based deduction that applies to all eligible assets within a certain class, while Section 179 is a dollar-based deduction that can be applied on an asset-by-asset basis.

• If the business use of property for which a Section 179 deduction was taken drops below 50% in a subsequent year, a portion of the deduction may be subject to recapture as taxable income.

• It's always recommended to consult with a tax professional to determine how Section 179 might benefit your specific business and to ensure compliance with all IRS regulations.
