Section 179 Tax Deduction: Everything you need to know
What is Section 179 and how can I use the tax deduction?
Section 179 lets businesses deduct the full purchase price of qualifying equipment or vehicles purchased, leased, or financed during the tax year. Instead of spreading the write-off over several years through depreciation, you can deduct the entire cost up front.
Example: Buy a $50,000 truck → deduct $50,000 this year (instead of $10,000/year over 5 years).
This incentive encourages small and medium businesses to invest in equipment now—not later.

Three Vehicle Categories Under Section 179
1. Vocational Trucks and Vans or Vehicles Over 14,000 lb. (100% Section 179 Deduction)
These vehicles generally have no personal‑use function and typically qualify for the full Section 179 deduction.
Qualifying examples include:
- Heavy trucks over 14,000 lb. GVWR
- Delivery trucks with minimal passenger seating
- Cargo vans with permanent commercial modifications (e.g., enclosed cargo area, no seating behind driver)
2. Certain Heavy SUVs & Passenger-Type Vehicles 6,000–14,000 lbs. GVW ($32,000 maximum Section 179 deduction; remaining eligible basis may qualify for bonus depreciation)
SUVs, trucks, and vans in this weight class have a special $32,000 Section 179 cap for 2026. The remaining eligible cost above $32,000 may qualify for bonus depreciation in 2026.
3. Cars, Light Trucks & SUVs Under 6,000 lbs. GVW ($20,300 maximum first-year deduction with bonus depreciation)
Traditional passenger vehicles are subject to special depreciation limits. For vehicles placed in service in 2026 and eligible for bonus depreciation, the maximum first-year deduction is $20,300 when used 100% for business.
Section 179 Qualified Financing Benefits
Section 179 does not require an upfront cash payment. Both purchases and non-tax capital leases can qualify, provided they meet the 50% business-use threshold and other IRS criteria.
Financing allows you to:
- Claim the full eligible deduction in 2026
- Spread payments over multiple years
- Improve cash flow while gaining immediate tax savings
What Is the Maximum Section 179 Deduction for 2026?
For 2026, businesses can deduct up to $2,560,000 in qualifying purchases. This represents the total amount you can write off under Section 179, provided your equipment meets these key criteria:
- Placed in service during the 2026 tax year
- 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 your equipment purchases exceed $4,090,000:
- Dollar-for-dollar reduction above $4,090,000
- Complete phase-out at $6,650,000
- Additional purchases may still qualify for bonus depreciation
How Do Carryover & Limitations Work?
Your Section 179 deduction generally cannot exceed your taxable income from the active conduct of a trade or business. If your allowable Section 179 deduction exceeds this income limitation, the unused portion generally carries forward to future tax years, subject to applicable limits.
Example: How Does Section 179 Generate Tax Savings?
This example illustrates how Section 179 can dramatically reduce your after-tax equipment costs. For a $3,000,000 purchase:

| Maximum Section 179 Deduction | $2,560,000 |
| 100% Bonus First-Year Depreciation | $440,000 |
| Total First-Year Deduction ($2.56M + $440K) | $3,000,000 |
| Tax Savings (assumes 35% tax rate) | $1,050,000 |
| Equipment Cost After Tax Savings | $1,950,000 |
Note: Qualifying property must be placed into service by December 31, 2026
