Home » 2026 Section 179 Deduction: Complete Guide & Limits

Updated: January 2026

Use Section 179 to expense qualifying business equipment and software in the year it’s placed in service. This guide covers the 2026 rules (tax years beginning in 2026), including current dollar limits, phase-outs, vehicle caps, and how Section 179 can be combined with bonus depreciation.








Note: The Section 179 deduction phases out dollar-for-dollar when the total cost of qualifying property placed in service exceeds $4,090,000 and is fully phased out at $6,650,000.

These limits are updated annually for inflation. For background on recent rule changes and effective dates, see our Legislative History page.

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

How the 2026 Deduction Limits and Phase‐Out Threshold Work

What Is the Maximum Section 179 Deduction for 2026?

For tax years beginning in 2026, businesses can elect to expense up to $2,560,000 of qualifying purchases. This is the maximum total Section 179 amount you can write off, subject to the taxable income limitation and the phase-out rules below.

  • Placed in service during the tax year you’re claiming the deduction
  • Used for business purposes more than 50% of the time
  • Qualifies under IRS guidelines

Spending Cap and Phase-Out Rules

The Section 179 deduction begins to phase out when the total cost of qualifying property placed in service exceeds $4,090,000:

  • Phase-out begins: above $4,090,000 of total qualifying property placed in service
  • Dollar-for-dollar reduction: the $2,560,000 limit is reduced by the amount over $4,090,000
  • Fully phased out: at $6,650,000
  • After Section 179: remaining basis may still qualify for bonus depreciation (if eligible)

How Does Section 179 Apply to Business Vehicles?

Special rules apply to vehicles:

  • Vehicles rated at 6,000 lbs. GVWR or less follow standard depreciation rules
  • SUVs over 6,000 lbs. GVWR but under 14,000 lbs. GVWR: Limited to $32,000 Section 179 deduction for certain SUVs
  • Vehicles over 6,000 lbs. GVWR such as heavy work trucks and vans may be eligible for full Section 179 expensing
  • Vehicles with beds at least six feet long are not subject to the SUV limitation

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
