Section 179 of the Internal Revenue Code lets small businesses deduct the full purchase price of qualifying equipment and software in the year they buy it — instead of spreading the cost over multiple years through depreciation. The One Big Beautiful Bill Act (OBBBA) nearly doubled the maximum deduction, making this one of the most powerful tax tools available to small businesses in 2026.
2026 Section 179 Limits at a Glance
| Detail | Pre-OBBBA (2025) | Post-OBBBA (2026) |
|---|---|---|
| Maximum deduction | $1.25 million | $2.56 million* |
| Phase-out threshold | $2.5 million | $4.09 million* |
| Heavy SUV limit | $30,500 | $32,000* |
| Inflation indexing | Yes | Yes (permanent) |
*2026 inflation-adjusted estimates. The OBBBA set base amounts at $2.5 million (deduction) and $4 million (phase-out) for tax years beginning after 2024, with annual inflation adjustments.
What Is Section 179?
Normally, when a business buys equipment or assets that last more than a year, it must “depreciate” the cost — deducting a portion each year over the asset’s useful life (called the recovery period). A $50,000 piece of equipment with a 5-year recovery period would yield $10,000 in deductions per year.
Section 179 lets you skip this waiting period and deduct the entire cost in Year 1. That $50,000 piece of equipment? You deduct all $50,000 in 2026.
This is not a loan or a deferral — it’s an immediate, permanent deduction that reduces your taxable income in the year of purchase.
What Property Qualifies for Section 179?
Qualifying Property
- Tangible personal property: Machinery, equipment, computers, furniture, tools
- Off-the-shelf software: Business software that’s available for purchase by the general public
- Business vehicles: Cars, trucks, vans, SUVs used for business (subject to limits)
- Certain improvements to nonresidential real property (OBBBA expanded):
- Roofs
- HVAC systems
- Fire protection and alarm systems
- Security systems
- Qualified improvement property (QIP): Interior improvements to nonresidential buildings
Property That Does NOT Qualify
- Buildings and structural components (other than the specific improvements listed above)
- Land and land improvements
- Property used outside the United States
- Property acquired from related parties
- Property used for lodging (hotels, rental apartments)
- Air conditioning or heating units for residential property
- Property held for investment (not used in active trade or business)
How Section 179 Works: Step by Step
Step 1: Buy Qualifying Property
Purchase and place the property in service during the 2026 tax year. “Placed in service” means the asset is ready and available for use in your business — not just ordered or paid for.
Step 2: Determine Business Use Percentage
The property must be used more than 50% for business. If it’s used 100% for business, you can deduct the full cost. If it’s used 75% for business, you can deduct 75% of the cost.
Step 3: Calculate Your Deduction
Your Section 179 deduction is the lesser of:
- The cost of the qualifying property (up to $2.56 million total)
- Your taxable business income for the year
Important: Section 179 cannot create or increase a business loss. If your business income is $80,000 and you buy $100,000 in equipment, your Section 179 deduction is capped at $80,000. The remaining $20,000 carries forward to future years.
Step 4: File Form 4562
Report your Section 179 deduction on IRS Form 4562 (Depreciation and Amortization), which attaches to your business tax return.
Section 179 vs. Bonus Depreciation
Both Section 179 and bonus depreciation let you deduct the full cost of assets in the year of purchase. But they have key differences:
| Feature | Section 179 | Bonus Depreciation |
|---|---|---|
| Dollar limit | $2.56 million (2026) | No limit |
| Can create a loss? | No — capped at business income | Yes — can create a business loss |
| Election required? | Yes — you must elect it | Automatic (opt out if you don’t want it) |
| Used property? | Yes | Yes (first use by taxpayer) |
| Phase-out | Begins at $4.09M total purchases | No phase-out |
| Real property improvements | Roofs, HVAC, fire, security | Qualified improvement property |
| Carryforward of unused amount | Yes | No (but loss carries forward) |
Strategy: Many businesses use Section 179 first (because you choose which assets to expense), then apply bonus depreciation to remaining qualifying property. Your tax advisor can help determine the optimal mix.
Vehicle Deductions Under Section 179
Business vehicles have special rules:
Heavy Vehicles (Over 6,000 lbs GVWR)
- Heavy SUVs: Section 179 capped at $32,000 (2026). Remaining cost can use bonus depreciation.
- Heavy trucks and vans: Full Section 179 deduction available (no SUV cap) — a heavy-duty pickup truck costing $70,000 can be fully deducted.
Passenger Vehicles (Under 6,000 lbs)
- Subject to “luxury auto” depreciation limits
- 2026 first-year limit with bonus depreciation: approximately $20,400
- Much lower limits in subsequent years
Record-keeping requirement: You must document your business use percentage with a mileage log or similar record. An app like SparkReceipt’s mileage tracker makes this effortless.
Common Section 179 Scenarios
Scenario 1: Freelance Photographer
| Purchase | Cost | Section 179 Deduction |
|---|---|---|
| Camera body and lenses | $8,500 | $8,500 |
| Lighting equipment | $3,200 | $3,200 |
| Editing computer + monitor | $4,800 | $4,800 |
| Studio furniture | $2,000 | $2,000 |
| Total | $18,500 | $18,500 |
At a 24% tax rate + self-employment tax savings, this deduction saves roughly $7,270 in taxes.
Scenario 2: Small Construction Company
| Purchase | Cost | Section 179 Deduction |
|---|---|---|
| Heavy-duty pickup truck | $72,000 | $72,000 |
| Excavator | $95,000 | $95,000 |
| Power tools and equipment | $15,000 | $15,000 |
| Office computer and software | $3,000 | $3,000 |
| Total | $185,000 | $185,000 |
At the 24% bracket, this saves approximately $44,400 in federal income tax alone — plus self-employment or payroll tax savings depending on structure.
Record-Keeping Requirements
To claim Section 179, you need documentation for each asset:
- Purchase receipt or invoice showing the date, vendor, item description, and cost
- Proof of payment (credit card statement, cancelled check, bank record)
- Date placed in service — when the asset was first used for business
- Business use percentage — especially important for vehicles and mixed-use equipment
- Asset description and category — for your depreciation schedule
Scan and store purchase receipts for every significant business asset. SparkReceipt’s AI scanner extracts the vendor, date, and amount automatically, creating a digital record that’s easily searchable at tax time. For large purchases, also save the invoice and any financing documents.
Frequently Asked Questions
Can I use Section 179 if I’m a sole proprietor or freelancer?
Absolutely. Section 179 is available to all business types — sole proprietors, LLCs, S-Corps, partnerships, and C-Corps. Freelancers who buy equipment for their business can deduct the full cost in the year of purchase.
Do I have to buy the equipment outright, or does financed equipment qualify?
Financed and leased-to-own equipment qualifies for Section 179. You can deduct the full purchase price in the year you place it in service, even if you’re making payments over several years. This means your tax savings can exceed your first-year payments.
What happens if I stop using the equipment for business?
If business use drops to 50% or below in any year during the recovery period, you may have to “recapture” some of the Section 179 deduction — meaning you’d owe taxes on the excess deduction. Keep documentation of ongoing business use.
Can I use Section 179 and bonus depreciation on the same asset?
Not exactly on the same portion. You can apply Section 179 to some assets and bonus depreciation to others. For heavy SUVs, you’d use Section 179 for the first $32,000 and bonus depreciation for the remainder. Your tax advisor can optimize the allocation.
What’s the deadline to purchase equipment for 2026 Section 179?
The equipment must be purchased and placed in service before December 31, 2026. “Placed in service” means it’s set up and ready for use — not just ordered. Plan ahead to avoid year-end rush deliveries.
Bottom Line
The OBBBA’s expansion of Section 179 to $2.56 million makes 2026 an excellent year for small businesses to invest in equipment, technology, and vehicles. Combined with permanently restored 100% bonus depreciation, you can deduct virtually any business asset purchase immediately.
The key is documentation. Keep receipts for every equipment purchase, track business use percentages, and maintain records of when each asset was placed in service. Start tracking your business purchases with SparkReceipt to ensure every deductible asset is documented and ready for tax time.
