What Is Section 179 (and Why Does It Matter in 2026)?

Section 179 of the Internal Revenue Code empowers businesses to deduct the full purchase price of qualifying equipment and software in the same tax year they’re put into service. Instead of stretching depreciation across several years, you can claim the entire cost upfront—dramatically improving your cash flow and creating immediate tax benefits.

Why Section 179 Matters for Your Business

• Immediate Tax Impact : Rather than waiting years for depreciation benefits, claim the deduction in 2026
• Enhanced Cash Flow : Keep more working capital in your business when you need it most
• Strategic Growth : Upgrade equipment sooner and maintain competitive advantages in your market

• Placed in service during the tax year you’re claiming the deduction

• Qualifies under IRS guidelines

Spending Cap and Phase-Out Rules

How Do Carryover & Limitations Work?

Your Section 179 deduction cannot exceed your business’s net taxable income. However, if your Section 179 election exceeds your taxable business income in a given year, you can choose a partial Section 179 election. Any unused portion of the deduction carries forward to subsequent tax years, allowing you to apply it once you have sufficient income. This means if you can’t fully utilize Section 179 in the current year, you retain the remaining deduction for future use—ensuring you never lose the benefit.

Example: How Does Section 179 Generate Tax Savings?

This simplified example illustrates how Section 179 can reduce after-tax equipment costs. It assumes the purchase qualifies, the business has enough taxable income to use the full Section 179 election, and any remaining basis is eligible for bonus depreciation. For a $2,750,000 purchase:

• Section 179 Deduction: $2,560,000
• Bonus Depreciation: $190,000(if eligible)
• Total Tax Savings: $962,500(assumes a 35% combined tax rate)
• Final Equipment Cost: $1,787,500
