The Section 179 deduction limit for tax year 2026 is $2,560,000, with a dollar-for-dollar phase-out once total qualifying purchases pass $4,090,000 (Rev. Proc. 2025-32). For 2025 returns, the limits are $2,500,000 and $4,000,000, doubled from the old $1,250,000/$3,130,000 schedule by the One Big Beautiful Bill Act (OBBBA). OBBBA also made 100% bonus depreciation permanent for property acquired after January 19, 2025, so most businesses can now write off the full cost of equipment, machinery, and heavy vehicles in year one.

Four Ways to Deduct Equipment Purchases:
Key Changes for 2026:
Current Expenses (Operating Expenses):
Long-Term Assets (Capital Expenses):
Long-term assets require special tax treatment. Without Section 179 or bonus depreciation, you'd have to deduct their cost over 5-39 years through regular depreciation. This ties up tax deductions for years.
Example:
You buy $100,000 of equipment (5-year MACRS property):
Without Section 179:
- Year 1: Deduct $20,000 (20%)
- Year 2: Deduct $32,000 (32%)
- Year 3: Deduct $19,200 (19.2%)
- Years 4-6: Deduct the remaining $28,800
- Full tax savings take six tax years to arrive
With Section 179:
- Year 1: Deduct $100,000 (100%)
- Immediate tax savings: $35,000 (at a 35% tax rate)
Legal Citation: IRC § 263(a) - Capital expenditures must be capitalized and depreciated unless an exception applies (Section 179, bonus depreciation).
The de minimis safe harbor allows you to immediately deduct the cost of property that costs $2,500 or less per item. This is the simplest deduction method.
Legal Citation: IRS Reg. 1.263(a)-1(f) - De minimis safe harbor for tangible property
✅ No dollar limit on total purchases - Deduct unlimited items under $2,500 each ✅ No Form 4562 required - Treated as operating expenses on Schedule C ✅ No depreciation schedules - No ongoing tracking required ✅ No recapture risk - If you later use the item personally, no tax penalty

Non-Qualifying Property:
Scenario: You purchase the following items for your business:
| Item | Cost | Qualifies? |
|---|---|---|
| Laptop | $2,200 | ✅ Yes |
| Office chair | $800 | ✅ Yes |
| Desk | $1,900 | ✅ Yes |
| Conference table | $3,200 | ❌ No (over $2,500) |
| Total qualifying | $4,900 | Immediate deduction |

❌ Don't use when:
Section 179 allows businesses to immediately deduct the full purchase price of qualifying equipment and software placed in service during the tax year, rather than depreciating it over time.
Legal Citation: IRC § 179 - Election to expense certain depreciable business assets
| Metric | 2026 Limit |
|---|---|
| Maximum deduction | $2,560,000 |
| Phase-out begins at | $4,090,000 |
| Complete phase-out at | $6,650,000 |
How Phase-Out Works:
For every dollar you spend above $4,090,000 in qualifying property, your Section 179 limit decreases by one dollar.
Example:
Total equipment purchases: $5,000,000
Excess over phase-out: $910,000 ($5M - $4.09M)
Available Section 179: $1,650,000 ($2.56M - $910K)
✅ Tangible Personal Property:
✅ Vehicles:
✅ Software:
✅ Qualified Real Property Improvements:
❌ Cannot use Section 179 for:
Critical Rule: Your Section 179 deduction cannot exceed your business's taxable income for the year.
Taxable business income includes:
Example: Income Limitation
Your business net income: $150,000
Equipment purchases: $250,000
Maximum Section 179 deduction: $150,000 (limited by income)
Unused Section 179: $100,000 → Carries forward indefinitely
Good News: Unused Section 179 deductions carry forward to future years when you have sufficient business income.
Property must be used more than 50% for business to qualify for Section 179.
Example:
| Scenario | Business Use | Qualifies? | Deduction |
|---|---|---|---|
| Delivery van | 100% | ✅ Yes | Full amount |
| Laptop | 75% | ✅ Yes | 75% of cost |
| Vehicle | 45% | ❌ No | Regular depreciation only |
Important: If business use drops to 50% or below in later years, you must recapture (pay back) the excess Section 179 deduction. See the depreciation recapture guide for how that income is reported.
First-Year Section 179 Limit: $32,000 (2026, Rev. Proc. 2025-32)
Examples of 6,000+ lbs vehicles:
Pickups with a cargo bed of at least six feet (many F-150, Sierra, and Ram 1500 configurations) escape the SUV cap entirely and qualify for full Section 179.
Calculation Example:
Purchase price: $80,000 (Chevrolet Suburban)
GVWR: 7,300 lbs
Business use: 100%
Section 179: $32,000 (2026 max for SUVs)
Remaining: $48,000
Bonus depreciation (100%): $48,000
Total first-year deduction: $80,000
For the standard-mileage-vs-actual-expense decision and the full vehicle write-off rules, see the business vehicle tax deduction guide.
No limit - Full Section 179 deduction available
Qualifying vehicles:
Example:
Purchase price: $55,000 (Ford Transit cargo van)
Section 179 deduction: $55,000 (full amount)
First-Year Limit: $20,300 (2026, including bonus depreciation, per Rev. Proc. 2026-15)
Required Form: IRS Form 4562 - Depreciation and Amortization
What to include:
Filing deadline: Must be filed with your timely-filed tax return (including extensions)
Use-It-or-Lose-It Rule: If you don't elect Section 179 on your original return, you generally cannot claim it later (though limited exceptions exist).
Bonus depreciation allows you to deduct a large percentage of an asset's cost in the first year you place it in service. For 2026, bonus depreciation is 100% of the asset's cost.
Legal Citation: IRC § 168(k) - Special depreciation allowance for certain property
| Year | Bonus Depreciation Rate |
|---|---|
| 2023 | 80% |
| 2024 | 60% |
| 2025 | 100% if acquired after Jan 19, 2025 (40% if acquired earlier) |
| 2026 | 100% |
| 2027+ | 100% (permanent under OBBBA) |
Major Change: The One Big Beautiful Bill Act (OBBBA, H.R.1, signed July 4, 2025) made 100% bonus depreciation permanent for qualified property acquired after January 19, 2025. Under the old TCJA phase-down it would have dropped to 40% in 2025 and 20% in 2026.
✅ Qualifying Property:
✅ Key advantage over Section 179:
| Factor | Section 179 | Bonus Depreciation |
|---|---|---|
| Maximum amount | $2,560,000 | Unlimited |
| Income limit | Yes (limited to taxable income) | No |
| Phase-out | Yes (at $4.09M purchases) | No |
| Used equipment | Yes | Yes |
| Can create NOL | No | Yes |
| Recapture risk | Yes (if business use drops below 50%) | Yes |
Optimal Strategy:
Example: Large Equipment Purchase
Total equipment purchases: $5,000,000
Taxable business income: $1,200,000
Strategy:
Step 1: Section 179: $1,200,000 (limited by income)
Step 2: Bonus depreciation (100%): $3,800,000
Total first-year deduction: $5,000,000
Tax savings (at 35% rate): up to $1,750,000 — $420,000 offsets
current-year income; the excess creates an NOL for future years
You can elect out of bonus depreciation for any asset class.
Why opt out?
How to opt out: Make an election statement on your tax return. The election applies to all property in the same asset class (e.g., all 5-year property).
MACRS (Modified Accelerated Cost Recovery System) is the standard method for depreciating property over its "useful life."
Legal Citation: IRC § 168 - Accelerated cost recovery system
✅ Use regular depreciation when:
| Asset Type | Recovery Period | Examples |
|---|---|---|
| 3-year property | 3 years | Tractors, race horses, breeding hogs |
| 5-year property | 5 years | Computers, cars, light trucks, office equipment |
| 7-year property | 7 years | Office furniture, desks, manufacturing equipment |
| 15-year property | 15 years | Land improvements, restaurant property |
| 27.5-year property | 27.5 years | Residential rental property |
| 39-year property | 39 years | Commercial buildings, nonresidential real property |
Two Methods:
Example: 5-Year Property (Computer Equipment)
Purchase price: $10,000
Method: 200% Declining Balance
Recovery period: 5 years
Year 1: $2,000 (20.00%)
Year 2: $3,200 (32.00%)
Year 3: $1,920 (19.20%)
Year 4: $1,152 (11.52%)
Year 5: $1,152 (11.52%)
Year 6: $576 (5.76%) ← Half-year convention
Note: MACRS uses a "half-year convention" - assumes property is placed in service mid-year, regardless of actual date.
Half-Year Convention (Default):
Mid-Quarter Convention:
Repairs:
Improvements (Betterments):
| Expense | Classification | Tax Treatment |
|---|---|---|
| Patching roof leak | Repair | Deduct immediately |
| Replacing entire roof | Improvement | Depreciate over 39 years (or Section 179) |
| Repainting building | Repair | Deduct immediately |
| Adding new wing | Improvement | Depreciate over 39 years |
| Fixing broken equipment | Repair | Deduct immediately |
| Equipment upgrade | Improvement | Depreciate or Section 179 |
| Oil change for vehicle | Repair | Deduct immediately |
| Engine replacement | Improvement | Depreciate |
Legal Citation: IRS Reg. 1.263(a)-3 - Amounts paid to improve tangible property
Cannot use Section 179 or bonus depreciation for:
Depreciation period:
Special rules for certain building improvements:
✅ Qualifies for Section 179 (nonresidential buildings only):
✅ Qualified improvement property (interior improvements to nonresidential buildings):
Requirements for QIP:
Example:
You install a new HVAC system in your office building: $150,000
Option 1: Section 179: $150,000 (immediate deduction)
Option 2: Regular depreciation: about $3,846 per year over 39 years
First-year difference: $146,154 more in deductions with Section 179
Bonus depreciation applies to building work only when it qualifies as QIP (interior improvements, 15-year property). A rooftop HVAC unit or a full roof replacement is 39-year building property, so Section 179 is the only immediate-expensing route for those.

Recommendation:
Tax savings: up to $2,100,000 at a 35% rate ($700,000 offsets current-year income; the rest carries forward as an NOL)
Calculation of phase-out:
Purchases: $6,000,000
Exceeds phase-out threshold by: $1,910,000 ($6M - $4.09M)
Section 179 limit reduced to: $650,000 ($2,560,000 - $1,910,000)

The Section 179 deduction allows businesses to immediately expense the full purchase price of qualifying equipment and property placed in service during the tax year, rather than depreciating it over several years. For 2026, the maximum Section 179 deduction is $2,560,000, with a phase-out beginning when total equipment purchases exceed $4,090,000. The deduction is limited to your taxable business income for the year, but unused amounts carry forward.
The bonus depreciation rate for 2026 is 100%, also referred to as the special depreciation allowance under IRC Section 168(k). The One Big Beautiful Bill Act made the 100% rate permanent for qualified property acquired after January 19, 2025; under the original TCJA phase-down it would have been just 20% in 2026. Bonus depreciation has no dollar limit and can create a net operating loss, making it useful when Section 179 is exhausted or limited by business income.
Vehicles eligible for Section 179 in 2026 depend on their gross vehicle weight rating (GVWR):
Heavy SUVs (6,001–14,000 lbs GVWR) — up to $32,000 Section 179 in 2026: Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, Toyota Sequoia, Cadillac Escalade, Lincoln Navigator, Mercedes GLS, BMW X7, Jeep Grand Cherokee L, Land Rover Defender, Tesla Model X
Heavy pickups with a 6-foot-plus bed and cargo vans/work trucks — full Section 179 (no SUV cap): Ford F-150/F-250/F-350 (long-bed configurations), Chevrolet Silverado 1500/2500, GMC Sierra, Ram 1500/2500, Toyota Tundra, Ford Transit, Ford E-Series, Mercedes Sprinter, Ram ProMaster, Chevrolet Express, GMC Savana
Passenger vehicles (under 6,000 lbs) — limited to $20,300 first-year (Rev. Proc. 2026-15): Most sedans, small SUVs, and crossovers fall in this category with lower deduction limits.
The special depreciation allowance is the official IRS term for what's commonly called "bonus depreciation." For 2026, the special depreciation allowance is 100% of the cost of qualifying property. It applies to both new and used assets with a recovery period of 20 years or less. The allowance is claimed on Form 4562, Part II (Special Depreciation Allowance). Unlike Section 179, the special depreciation allowance has no dollar cap and no business income limitation.
The 2026 depreciation rules provide three main options for deducting business assets: (1) Section 179 expensing for immediate deduction up to $2,560,000, (2) 100% bonus depreciation (special depreciation allowance) with no dollar limit, and (3) regular MACRS depreciation over 3-39 years depending on asset type. Most businesses should use Section 179 first (up to their taxable income limit), then bonus depreciation for any excess, and regular MACRS only when they want to spread deductions over future years.
Equipment deductions represent one of the most powerful tax-saving opportunities for business owners. With the 2026 Section 179 limit at $2,560,000 and 100% bonus depreciation available, you can immediately deduct virtually unlimited equipment purchases—turning every dollar spent on business assets into immediate tax savings.
The key is strategic planning:
Remember: The difference between depreciating equipment over 7 years versus deducting it immediately in Year 1 can mean hundreds of thousands of dollars in time-value of tax savings. Every piece of equipment you buy is an opportunity to reduce your tax bill—but only if you know how to properly claim the deduction.
