What Section 179 Does

Section 179 of the IRS code lets businesses deduct the full purchase price of qualifying equipment in the year the equipment is placed in service, rather than depreciating it gradually over 5–10 years. For 2026, the maximum Section 179 deduction is $1,160,000 with a phase-out beginning at $2,890,000 of total equipment placed in service.

Critically, Section 179 applies to financed equipment too — you can deduct the full purchase price even if you only paid 10% of it as down payment. That timing mismatch (large deduction now, payments over years) is exactly what makes equipment financing combined with Section 179 so tax-efficient.

This is general tax information, not personal tax advice. Consult your accountant for application to your specific situation.

How Section 179 Works With Equipment Financing

Walking through a concrete example: you finance a $200,000 piece of equipment with 10% down ($20,000) and a 5-year loan for the remaining $180,000.

  • Cash spent in year 1: $20,000 down payment + ~$45,000 in loan payments = ~$65,000
  • Section 179 deduction in year 1: $200,000 (full purchase price)
  • Tax savings (assuming 25% effective tax rate): $200,000 × 25% = $50,000
  • Net cash impact year 1: $65,000 cash out − $50,000 tax savings = $15,000 net cash out

You acquired $200,000 of equipment and effectively spent $15,000 net in year 1. The remaining loan payments occur in years 2–5, but those years no longer benefit from Section 179 — depreciation is already taken.

This is why Section 179 timing matters. Taking the deduction in a year you have strong taxable income produces significantly more tax benefit than spreading depreciation over 5+ years.

Qualifying Equipment for Section 179

Equipment must be:

  • Tangible business property — not real estate, not intangibles
  • Used more than 50% for business — personal-use percentage is excluded
  • Acquired by purchase — financed purchases qualify; operating leases do not (since you don't own the equipment)
  • Placed in service during the tax year — not just purchased, but actually in operation

Qualifying categories: machinery, equipment, vehicles (with limits), computers, off-the-shelf software, office furniture, and certain improvements to non-residential real property.

Vehicle limits: heavy SUVs (over 6,000 lb GVW) qualify for full Section 179 up to $30,500. Light vehicles have lower limits. Heavy trucks, vans, and equipment vehicles have higher allowances.

Section 179 Limits and Phase-Outs

Three key limits for 2026:

  • Maximum deduction: $1,160,000 per business per year
  • Phase-out threshold: Begins at $2,890,000 in total equipment placed in service. Above this, the maximum deduction reduces dollar-for-dollar.
  • Income limit: Section 179 deduction can't exceed your taxable business income. Excess can be carried forward to future years.

For most small and mid-sized businesses, none of these limits are binding. The maximum deduction matters mostly for businesses making large equipment investments in a single year. The income limit matters for businesses with limited taxable income (the deduction can't create a loss carryforward beyond what bonus depreciation already does).

Section 179 vs Bonus Depreciation

Bonus depreciation is a separate tax provision that can also let you deduct equipment in the year of purchase. Key differences from Section 179:

  • No dollar cap on bonus depreciation. Section 179 caps at $1.16M; bonus depreciation has no cap.
  • Bonus depreciation can create a net operating loss (NOL). Section 179 is limited to taxable income.
  • Bonus depreciation percentage is phasing down. 2025: 40%, 2026: 20%, 2027: 0% under current law (subject to legislative change).
  • Section 179 is selective. You can choose to apply Section 179 to specific equipment and not others. Bonus depreciation generally applies to all qualifying equipment.

For most businesses, the strategy is: use Section 179 first (up to the cap and the income limit), then use bonus depreciation for any remaining equipment cost. Your accountant should run both for your specific situation.

Practical Strategy: Combining Financing With Section 179

The combination of equipment financing and Section 179 produces three practical advantages:

1. Cash conservation. You preserve operating cash by financing the equipment, while still capturing the full tax deduction in year 1. The deduction reduces your tax bill by an amount that often exceeds your year-1 down payment.

2. Tax timing flexibility. If you have a strong tax year coming, accelerating equipment purchases into that year captures the largest possible benefit. Some businesses time equipment purchases specifically for Section 179 optimization.

3. Avoid the lease tradeoff. Operating leases don't qualify for Section 179, since you don't own the equipment. Equipment financing or $1 buyout leases preserve Section 179 eligibility, which is often the deciding factor in lease vs finance decisions.
