Section 179 and Bonus Depreciation 2026: The Complete Tax-Driven Equipment Financing Strategy Guide

1. The 2026 Tax Reset: Why This Year Is Different

For five years, bonus depreciation was on a death march. The 2017 Tax Cuts and Jobs Act locked in 100% bonus expensing through 2022, then began stepping it down 20 points per year: 80% in 2023, 60% in 2024, 40% in 2025, on track to hit zero by 2027. Operators who timed equipment purchases against that ramp made very different decisions than operators who didn't. Then, on July 4, 2025, the One Big Beautiful Bill Act (Public Law 119-21) blew the schedule up.

OBBBA didn't just pause the phase-down — it restored 100% bonus depreciation permanently for qualifying property acquired and placed in service after January 19, 2025, per Grant Thornton's depreciation alert. The IRS followed with Notice 2026-11 in January 2026, providing interim guidance on the acquisition-date rules and binding-contract exceptions that determine whether your 2025 purchase qualifies at 100% or the legacy 40%.

At the same time, Section 179 limits jumped. Rev. Proc. 2026-15 set the 2026 maximum at $2,560,000 with phase-out starting at $4,090,000 — a doubling from the pre-OBBBA $1.25M cap, per Section179.org. The full phase-out point is $6,650,000, meaning genuinely large equipment buyers still benefit from Section 179 but middle-market operators between $4M and $6.65M of placed-in-service property need to model the haircut carefully.

The macro effect has been immediate. The Equipment Leasing and Finance Association's Capex Finance Index reported $11.6B in new equipment-finance volume in January 2026 — a record monthly figure, driven heavily by operators front-loading purchases to lock in 100% bonus on assets they would have otherwise spread over MACRS recovery periods.

For a broader view of how depreciation fits into the full architecture of business capital, see our complete guide to capital stacking and our explainer on what your accountant doesn't know about business funding.

A second under-discussed reset: the political durability of permanent 100% bonus depreciation. Past tax reforms have been reversed within an election cycle — we saw it with the 2017 phase-down. The current Congressional framing makes a near-term repeal unlikely, but "permanent" in tax legislation means "until the next major bill." For operators making 10-year capital decisions, model the strategy assuming the rule could change in 2029-2031. Buy what you actually need now; don't lock in long-dated debt service betting that the deduction will be available identically in five years.

2. Section 179 Mechanics: How It Actually Works

Section 179 of the Internal Revenue Code lets a business elect to expense the cost of qualifying tangible property in the year placed in service, rather than capitalizing and depreciating it over the asset's MACRS class life. It's an election, not an automatic treatment — you choose how much to expense on Form 4562, asset by asset, up to the annual cap.

The Three Hard Limits

The taxable income limitation is the one that catches operators off guard. If your business generates $400K of taxable income before the §179 deduction and you try to expense $800K of equipment, only $400K runs through §179 — the remaining $400K carries forward indefinitely. Bonus depreciation has no such restriction.

When the Phase-Out Actually Bites

Most operators never hit the phase-out threshold — the $4.09M trigger is a high bar. But middle-market manufacturers, large fleet operators, and commercial real-estate buyers running cost segregation often clear it. At that point, the layering question becomes mathematical: each dollar of qualifying property between $4.09M and $6.65M reduces §179 capacity by exactly one dollar. Above $6.65M of placed-in-service property, §179 is zero. Bonus depreciation has no equivalent phase-out, which is why high-capex operators rely on bonus as the primary lever and use §179 only on strategic carve-outs (state-conformity assets, QIP, mixed-class assets where per-asset granularity matters).

What Section 179 Requires

• Tangible personal property — machinery, vehicles (with caps), computers, off-the-shelf software, and certain qualified improvement property to nonresidential real estate
• More than 50% business use in the year placed in service. Drop below 50% in a later year and you trigger recapture (covered in Section 19)
• Acquired by purchase from an unrelated party — not inherited, gifted, or bought from a related entity
• Placed in service during the tax year — meaning ready and available for its intended use, not merely ordered or delivered

3. Bonus Depreciation: 100% Is Back, Permanently

Bonus depreciation under IRC §168(k) lets a business take an immediate percentage write-off on qualifying property in the year placed in service, on top of (or instead of) regular MACRS depreciation. From 2017 through January 19, 2025, the percentage stepped down: 100%, 80%, 60%, 40%. OBBBA reset it to 100% permanently for property acquired and placed in service after January 19, 2025.

The Acquisition-Date Trap

The bill draws a sharp line at January 19, 2025. Property acquired on or before that date and placed in service in 2025 falls under the legacy phase-down (40% bonus); property acquired after that date qualifies for 100%. The IRS clarified the acquisition-date mechanics in Notice 2026-11, including how binding written contracts and self-constructed property are treated.

For purchased property, acquisition is generally the date of a binding contract. For self-constructed property, it's when physical work of a significant nature begins. The 10% safe harbor — that work is "significant" once 10% of total cost is incurred — remains available. The Iowa State CALT analysis walks through the edge cases in detail.

Bonus vs §179 — The Loss Question

The fundamental structural difference: Section 179 cannot create or increase a net operating loss. Bonus depreciation can. If your business has $200K of taxable income and you place $1M of equipment in service, §179 caps out at $200K. Bonus runs through all $1M, generating an $800K NOL that you carry forward to offset future income. For high-growth businesses front-loading capex before profitability scales, bonus is the lever.

4. Section 179 vs Bonus Depreciation: The Decision Framework

Both deductions accelerate cost recovery. They differ in flexibility, income interaction, state conformity, and recapture mechanics. Sophisticated operators don't pick one — they layer them.

The Layering Strategy

The textbook order: Section 179 first, then bonus depreciation, then regular MACRS on the residual basis. But "first" doesn't mean "always max it out." Smart layering means:

• Use §179 on assets where you want per-asset control — e.g., expense the new CNC at 100% via §179, but only partially expense the office furniture so you preserve depreciation for next year's projected higher income
• Use §179 on assets in states that conform, then run bonus on the rest if your state decouples from federal bonus
• Use bonus when you need to generate an NOL — or when §179's income cap binds
• Use §179 when you want to avoid state add-back complexity in conforming states

5. Stacking 179 + Bonus + MACRS in a Single Tax Year

For an operator placing $1M+ of mixed-class property in service in a year, the optimal play is rarely "elect §179 max, take bonus on rest." It's a four-step layering exercise that requires modeling.

Note the strategic choice: §179 is used on the longest-class-life assets (yard equipment, QIP) because the time value of acceleration is highest there — the alternative is recovery over 7 or 15 years. Bonus is used on the trailers (5-year MACRS) where the deferral period is shorter and the income-cap flexibility doesn't matter.

For operators in trucking and logistics specifically, this stacking exercise often plugs into broader equipment-finance structures — see our equipment financing complete guide and equipment lease vs buy vs finance for the capital-side architecture.

6. What Qualifies: The Comprehensive List

Both §179 and bonus depreciation cover the same broad universe of tangible business property, but the edge cases differ. The IRS publishes the authoritative list in Publication 946; here is what we see most often in client capital stacks.

Tangible Personal Property (5-Year and 7-Year MACRS)

• Machinery and production equipment — CNC mills, lathes, presses, injection-molding equipment, packaging lines
• Computers, servers, networking gear, printers, point-of-sale systems
• Office furniture, fixtures, cubicles, conference tables
• Tools and shop equipment — lifts, compressors, welders, diagnostic equipment
• Restaurant equipment — ovens, walk-ins, refrigeration, dishwashers, hood systems
• Medical and dental equipment — imaging machines, dental chairs, lab equipment
• Construction equipment — excavators, skid steers, dump trucks, attachments
• Agricultural equipment — tractors, combines, irrigation, grain bins

Vehicles (Subject to GVWR Tiers — See Section 10)

• Heavy SUVs/trucks/vans 6,001–14,000 lb GVWR — §179 capped at $32,000 in 2026, remaining basis runs through bonus
• Vehicles over 14,000 lb GVWR — no §179 or §280F cap; full §179 and bonus available (semi-trucks, dump trucks, large work vans)
• Passenger autos — capped under §280F luxury auto limits ($20,300 first-year with bonus in 2026)
• Qualified non-personal-use vehicles — ambulances, hearses, vehicles seating 9+ behind driver, vehicles with cargo area 6+ feet not accessible from cabin

Real Estate Improvements

• Qualified Improvement Property (QIP) — interior improvements to nonresidential real property placed in service after building first placed in service; 15-year MACRS, bonus-eligible, §179-eligible
• Roofs on nonresidential real property — §179-eligible (not bonus-eligible unless qualifies as QIP)
• HVAC, fire protection/alarm systems, security systems on nonresidential real property — §179-eligible
• Cost-segregated 5-year, 7-year, and 15-year components carved out of a building purchase — bonus-eligible (see Section 13)

Software

Off-the-shelf computer software is §179-eligible and 100% bonus-eligible. Custom-developed software is generally treated as a §174 research expenditure (subject to its own amortization rules under OBBBA — that's a separate conversation).

7. What Doesn't Qualify (and Where Operators Get Burned)

More money is lost to misunderstanding the disqualifiers than to optimizing the deduction. Here is the full disqualification matrix as we encounter it in the field.

Categorically Ineligible

• Land — never depreciable
• Buildings themselves — residential rental (27.5-year) and nonresidential (39-year) are not §179 or bonus eligible. Components carved out via cost segregation may be.
• Property held for investment — must be used in active trade or business
• Property used predominantly outside the U.S.
• Property leased to a government entity, tax-exempt entity, or foreign person
• Inventory — expensed as COGS, not depreciated
• Intangibles — goodwill, customer lists, patents (§197 amortization, not §179)
• Property acquired from a related party (defined under IRC §267 and §707(b))
• Property acquired by gift, inheritance, or like-kind exchange (carryover basis)

§179-Specific Restrictions

• Rental of personal property to others by individual lessors (unless meets active-business tests)
• Lodging property and property used in connection with lodging (with limited exceptions for hotels/motels)
• Property used 50% or less for business in the year placed in service

The "Used by Taxpayer" Trap on Bonus

Bonus depreciation requires that the property was not previously used by the taxpayer. If your S-corp leases a piece of equipment in 2024, then exercises a buyout in 2026, the buyout typically doesn't qualify for bonus — you've been "using" it. Same for upgrades within a trade-in cycle. Structure matters.

8. Financing Integration: The Capital-Side Mechanics

Here is the single most important fact about §179 and bonus depreciation that operators routinely miss: you can fully deduct equipment that you financed. The IRS does not care whether you paid cash or borrowed the money — what matters is that you placed the property in service and you bear the burdens and benefits of ownership.

This is what makes §179 and bonus depreciation a financing tool, not just a tax tool. Consider the cash flows:

That's the entire game. You wrote off an asset you paid 10% for, and the tax savings more than covered the down payment and first-year debt service. Years 2-5, the deduction doesn't repeat — you've used it — but you have an income-producing asset on the books and a manageable monthly debt service.

The Financing Vehicles That Work With §179/Bonus

• Equipment Finance Agreements (EFAs) — You're treated as the owner immediately; full §179/bonus available. The most common structure for §179 stacking.
• SBA 7(a) loans for equipment — Eligible; SBA does not preclude §179/bonus. See our SBA loan products complete guide.
• SBA 504 loans for major equipment + real estate combos — Equipment portion is depreciable; real estate is depreciated separately. See SBA 504 real estate loan guide.
• $1 buyout leases / capital leases — Tax-treated as purchases; full §179/bonus available.
• Bank term loans secured by equipment — You're the owner; §179/bonus fully available.
• Business lines of credit used to purchase equipment — same treatment as cash purchase. See our business lines of credit guide.

What Doesn't Work for Full Year-One Expensing

• True operating leases (FMV leases) — Lessor owns the equipment; you deduct lease payments as ordinary expense, not §179/bonus.
• TRAC leases without ownership intent — Treatment depends on facts and circumstances; often operating-lease treatment.
• Sale-leaseback structures where you sell to lessor and lease back — You may have already taken depreciation, then face recapture.

9. Lease vs Loan: The Tax-Optimized Choice

The "lease vs buy" debate usually gets framed as a cash-flow comparison. From a tax-stacking perspective, it's a choice between deduction structures: deduct the asset all at once (purchase or capital lease + §179/bonus) versus deduct the lease payment over the lease term (operating lease).

For a detailed walkthrough of how to choose between these structures for non-tax reasons (covenants, residual risk, off-balance-sheet treatment, total cost of capital), see our equipment lease vs buy vs finance complete guide.

10. Vehicle Depreciation: The Three-Tier System

Vehicles get their own depreciation regime under IRC §280F and the heavy SUV provisions. The rules sort vehicles into three GVWR tiers, each with sharply different tax outcomes. Eide Bailly's 2026 auto depreciation limits and Block Advisors' vehicle list are the canonical references.

Tier 1: Passenger Autos (Under 6,000 lb GVWR)

Subject to the §280F "luxury auto" caps. For 2026:

In practice, an $80,000 BMW used 100% for business takes about 8 years to fully depreciate under §280F. The luxury auto caps are why operators reach for GVWR over 6,000 lb.

Tier 2: Heavy SUVs, Trucks, Vans (6,001–14,000 lb GVWR)

Section 179 capped at $32,000 in 2026 (up from $30,500 in 2025). The remainder of the basis can run through 100% bonus depreciation. So a $130,000 vehicle in this tier with 100% business use:

If business use is 80%, the deductible basis is $104,000, the §179 cap stays at $32,000, and bonus runs against the remaining $72,000.

Tier 3: Over 14,000 lb GVWR (and Qualified Non-Personal-Use Vehicles)

No §280F cap. No §179 SUV limit. Full §179 (up to overall cap) and 100% bonus available. This is the tier for semi-tractors, large dump trucks, large box trucks, fleet vans, and qualified non-personal-use vehicles like ambulances.

11. The G-Wagon Deduction: Mechanics, Reality, and What It's Actually For

No tax topic generates more operator content than the "G-Wagon deduction." Most of it is wrong, misleading, or borderline reckless. Here is what the actual mechanics look like, drawn from Fraim CPA's G-Wagon analysis and clean §168(k)/§179 application.

Why the G-Wagon Works

The Mercedes-Benz G-Wagon (G550, G63 AMG) has a GVWR of 7,057 lb — comfortably in the 6,001–14,000 lb heavy SUV tier. So it bypasses §280F luxury auto caps entirely and is eligible for $32,000 of §179 (2026) plus 100% bonus depreciation on the remainder, scaled by business use percentage.

Where the G-Wagon Strategy Falls Apart

• Business use must exceed 50% — documented with contemporaneous mileage logs. Not a guess. Not "I drive it to client meetings sometimes."
• Drop below 50% in a later year and you trigger recapture — the depreciation accelerated over MACRS comes back as ordinary income.
• Personal use must be added back as compensation on the W-2 of any owner-employee using the vehicle personally.
• The vehicle still has to make business sense — the IRS hates the "I bought a $200K vehicle because I'm a real estate agent and I drive clients sometimes" fact pattern. They will probe.
• Sell or convert to personal use and recapture hits at ordinary rates, not capital gains rates.

12. Industry-Specific Playbooks

The §179/bonus strategy looks different in every industry because the asset mix, financing options, and revenue patterns differ. Here is how we approach the most common verticals in our client base.

Trucking and Logistics

Class 8 tractors (over 14,000 lb GVWR) get full §179 and bonus with no luxury auto caps. Trailers are 5-year MACRS, both §179 and bonus eligible. The play: SBA 7(a) financing on the foundational fleet (10-15 year amortization on the equipment portion) layered with EFA financing on incremental tractor adds at 4-6 year terms. Use §179 to drop taxable income on incremental fleet expansion; reserve bonus for the larger SBA-financed acquisitions where the loss flexibility matters.

Construction

Heavy equipment (excavators, dozers, dump trucks over 14,000 lb) is fully bonus/§179 eligible. Used equipment qualifies as long as it's new-to-the-taxpayer. Many construction operators run S-corps with K-1 income flowing to owners' personal returns — the §179 income limit applies at both the entity and shareholder level, which complicates the cap. Construction also tends to have big revenue swings, making the §179 income cap a binding constraint in lean years. Bonus is often the better lever.

Manufacturing

CNC machinery, injection molders, packaging lines, robotics — 7-year MACRS, fully eligible for both. Manufacturers tend to be the operators most affected by the §179 phase-out because a single CNC machine line can run $1-3M. Modeling §179 vs bonus across a $4M+ capex year is critical — this is where the layered strategy in Section 5 pays off.

Medical, Dental, Veterinary Practices

Imaging equipment, dental chairs, lab gear — 5-7 year MACRS, fully eligible. Often financed via specialty medical EFAs at attractive rates. The §179 strategy interacts heavily with the QBI deduction (§199A) phaseouts for specified service trades — we coordinate with the practice's CPA, not replace them.

Restaurants and Hospitality

Kitchen equipment, walk-ins, HVAC, fire suppression, point-of-sale — all eligible. Restaurant FF&E (furniture, fixtures, equipment) is the canonical §179 stack. Combine with QIP buildout for a $300-500K opening capex that fully expenses year one. Tight working capital management is critical here; we layer SBA 7(a) for the buildout and equipment with a tier-1 line of credit for operations.

E-commerce and Light Industrial

Warehouse racking, conveyors, robotics, packaging, forklifts (5-7 year), plus QIP on the building interior. Often the QIP carve-out is bigger than the operating equipment — cost segregation (Section 13) is the lever.

13. Cost Segregation: Carving Bonus-Eligible Assets Out of Real Estate

Buy a commercial building outright and you're staring at 39-year straight-line depreciation. That's the textbook. The reality: a meaningful portion of any commercial building — sometimes 20-40% — is actually 5-year, 7-year, or 15-year property if you carve it out properly. That carving exercise is called cost segregation, and it's the single biggest depreciation play in commercial real estate.

What Cost Segregation Identifies

• Removable carpet, decorative lighting, specialty plumbing — 5-year
• Specialty electrical (process power, dedicated circuits) — 5-7 year
• Office furniture, partitions, certain millwork — 7-year
• Land improvements: paving, landscaping, fencing, signage, exterior lighting — 15-year
• Qualified Improvement Property components — 15-year

The Bonus Multiplier

Everything carved into 5-year, 7-year, or 15-year property is 100% bonus eligible under OBBBA. So a $5M commercial building purchase that conventionally would deduct $128K/year (5M / 39) might generate $1.2-1.5M of year-one bonus depreciation after a cost segregation study.

Cost seg studies typically run $5K-$25K depending on building size and complexity. The math almost always works for buildings over $1M. Below that, the engineering fee eats the benefit.

14. Three Full Capital Stack Examples

Here is how the tax and financing structures actually fit together in real client situations. Names removed, numbers rounded, structures preserved.

Example A: Manufacturing Expansion, $2.4M Capex

Example B: Trucking Fleet Add, $1.1M

Example C: Multi-Location Restaurant Group, $750K Opening Capex

15. Year-End Execution Checklist

The deduction is won or lost in November and December. Here is the operational checklist we run with clients heading into year-end:

By October 31

• Run a YTD taxable income projection with your CPA — what number are we trying to manage?
• Inventory planned Q4 capex — what's been ordered, what's pending, what's contemplated?
• Confirm financing facilities are in place for any equipment you intend to acquire (no last-minute scramble)
• Begin acquisition-date documentation on any binding contracts (relevant for OBBBA §168(k) transition rules)

By November 30

• Equipment to be expensed in current year should be ordered with delivery confirmed before December 15
• Coordinate install schedules — electricians, plumbers, network — ensure placed-in-service is feasible by December 31
• For vehicles, confirm GVWR on every unit (doorjamb sticker photo to file)
• For QIP buildouts, ensure substantial completion timeline

By December 15

• Equipment delivered, installed, operational. Photograph every asset in operation, dated.
• Vehicles registered, plated, insured, in business use. Mileage logs started.
• Final taxable income projection reviewed; §179 vs bonus allocation decided in concept
• If capex exceeds §179 phase-out threshold, confirm the bonus layering with CPA

By December 31

• All target assets placed in service (ready and available for use, not just delivered)
• Documentation file complete: invoices, install dates, photographs, GVWR confirmations, business-use logs
• Confirm financing has closed; UCC filings recorded; payment streams active

16. Audit Red Flags and Documentation Discipline

The IRS examines §179/bonus claims with predictable focus on a small set of fact patterns. Here is the audit trigger map.

Top Audit Triggers

• Vehicles claiming 100% business use — especially expensive vehicles owned by operators with no W-2 employees driving them. The IRS knows the population of S-corp owners who allegedly drive their $150K SUV exclusively for business.
• Large §179 election by a low-revenue entity — $300K §179 on a $400K revenue business invites scrutiny on the taxable income limit.
• Related-party purchases — especially equipment transferred between commonly-owned LLCs at non-arm's-length pricing.
• Placed-in-service date right at year-end — December 28-31 placed-in-service dates with no contemporaneous evidence of operation.
• Mixed-use property where business-use percentage shifts dramatically year to year — signals undocumented usage allocation.
• Section 179 carryforward without entity-level explanation — suggests the taxable income limit was missed.

Documentation Disciplines That Withstand Audit

• Purchase contract or invoice with date, vendor, payment terms, asset description
• Bill of lading or delivery receipt
• Install completion documentation (electrician sign-off, network turn-up, calibration certificate)
• Photograph of asset in operation, dated, on premises
• For vehicles: registration, insurance binder, GVWR documentation, mileage logs (contemporaneous — not reconstructed)
• For mixed-use: usage logs with date, time, purpose, mileage where applicable
• Loan documents and UCC filings showing the business as borrower/debtor
• For QIP: scope of work, before/after photos, certificate of occupancy or equivalent

17. State Conformity: The Map That Determines Real Savings

Federal §179 and bonus deductions are only half the equation. Your state's conformity determines whether you actually get the matching state tax savings — or whether you'll be book-tax-reconciling for years.

Three Categories of States

• Full conformity: Match federal §179 cap and bonus depreciation in full. Examples: Florida, Texas (no income tax), Tennessee, Colorado.
• Partial conformity: Adopt §179 with state cap, decouple from bonus entirely or partially. Examples: New York, New Jersey, Pennsylvania.
• Major decoupling: Severely restrict §179 cap, no bonus. Example: California ($25K §179, no bonus).

State Behavior at a Glance (2026 — verify current rules)

Confirm current-year rules with your CPA — states change conformity rules regularly. LSL CPAs maintains a useful California reference; many state CPA societies publish similar tracking.

18. Equipment Lenders That Understand §179 Stacking

Not every equipment lender structures financing in a way that preserves §179/bonus eligibility cleanly. The wrong lease form, the wrong UCC structure, or the wrong residual treatment can convert what should be a capital lease (deductible) into an operating lease (not §179-eligible). Lender selection matters.

Lender Categories We Use

• Specialty equipment finance companies — Crest Capital, Balboa Capital, Beacon Funding, North Mill Equipment Finance. Fast underwriting, EFA structures, broad equipment universe.
• Bank equipment finance divisions — Wells Fargo Equipment Finance, Bank of America Equipment Finance, PNC Equipment Finance. Lower rates for established credits, slower underwriting.
• Captive finance arms — John Deere Financial, Caterpillar Financial, PACCAR Financial, Daimler Truck Financial. Manufacturer-tied, often promotional rates, structure must be verified for §179 eligibility.
• SBA preferred lenders — for the larger 7(a) and 504 deals. See our coverage of SBA cumulative loan limits.
• Tier-1 banks for working capital lines — Chase, Bank of America, Amex Business, US Bank, Wells Fargo. These are the stacking-eligible banks we deploy for clients building business credit alongside equipment deals.

What to Confirm Before Signing

• Document is structured as a finance agreement or $1 buyout / 10% PUT lease (not FMV)
• Business is named as borrower/debtor, not lessee under operating lease
• UCC-1 filing identifies your entity as debtor
• End-of-term ownership transfers automatically or for nominal consideration
• No early termination clauses that void ownership intent
• For SBA-financed equipment, the SBA authorization language doesn't impose restrictions inconsistent with §179 ownership tests

19. Recapture: The Tax You Owe If You Exit Wrong

Depreciation is not a permanent tax reduction — it's a timing benefit. When you dispose of an asset, convert it to personal use, or drop below the 50% business-use threshold, the IRS recaptures some or all of the accelerated depreciation as ordinary income. This is where unsophisticated operators get caught.

The Three Recapture Triggers

1. Sale or disposition at a gain — the gain up to depreciation taken is recaptured as ordinary income (§1245 property), not capital gain. Above-basis gain is capital.
2. Conversion to personal use — treated as a deemed disposition at FMV; depreciation recapture applies.
3. Business use drops below 50% — in any year before the end of MACRS recovery, all prior §179 and bonus depreciation in excess of straight-line MACRS gets added back as ordinary income in the year of conversion.

Recapture Worked Example: G-Wagon Sold at Year 4

Note: The 0% capital gains rate that some operators dream of? Not available. Depreciation recapture under §1245 is taxed at ordinary rates up to the amount of depreciation taken. Only gain in excess of original cost qualifies as capital gain.

Strategies to Manage Recapture

• Hold until end of MACRS recovery — no acceleration to recapture
• Time disposal to a low-income year — recapture stacks on ordinary income; better to recognize in a year you're already in a lower bracket
• Like-kind exchange (now real-estate only under post-TCJA §1031) — equipment-to-equipment 1031s were eliminated; if you're rolling equipment, you trigger recapture
• Maintain business-use percentage above 50% through the recovery period — especially critical on vehicles
• Don't convert to personal use casually — the moment business use drops below 50%, you've triggered the recapture calc

20. Special Situations and Interactions With Other Funding Tools

Section 179 and bonus depreciation interact with virtually every other capital tool a business uses. Here are the interactions we see most often in client engagements, with pointers to the deeper coverage for each.

§179 With SBA Business Acquisition Financing

When you acquire a business using SBA business acquisition financing, the purchase price allocation between assets and goodwill drives the depreciation outcome. Equipment, FF&E, and tangible property allocated in the purchase agreement become §179/bonus-eligible at the buyer's basis. Goodwill amortizes over 15 years under §197. Push the allocation toward tangible assets (within fair-market reason) and you front-load deductions; allocate too much to goodwill and you spread the deduction over 15 years. Quality-of-earnings work is critical here — see our quality of earnings (QoE) complete guide for how the allocation gets defended.

§179 in International Trade and Export Operations

Operators using the SBA International Trade Loan (ITL) program to acquire equipment for export-oriented operations face an additional wrinkle: §179/bonus property must be used predominantly within the United States. Equipment that you finance domestically but deploy abroad fails the §168(g)(1)(A) predominantly-U.S.-use test. The deduction is the depreciation under the Alternative Depreciation System (ADS), which is straight-line over a longer recovery period — not §179, not bonus. Structure your operations so domestic-use equipment is U.S.-domiciled; export inventory and overseas-deployed assets are separately tracked.

§179 With ROBS, Asset Depletion, and Alternative Capital Sources

Operators capitalizing a business through a ROBS (Rollover for Business Startups) structure should be aware that the C-corp formed under ROBS retains §179/bonus eligibility on equipment purchases like any other C-corp — the funding source doesn't affect the deduction. Similarly, businesses using asset depletion loans for owner-side capital deployment can still run §179/bonus through the operating entity. The eligibility test is at the operating entity level, not the capital source.

§179 With Working Capital Financing

Aggressive year-end §179/bonus elections create cash-flow consequences in subsequent quarters. The deduction reduces current tax but doesn't change cash needs; if you wrote off $1M and the IRS gives you back $370K in tax savings, the other $630K of equipment cost still has to be paid down via debt service. We typically stack working capital tools alongside the equipment financing to absorb the cash-flow squeeze: invoice factoring or AR financing for clients with receivables cycles, purchase order financing for inventory-driven operations, and revenue-based financing for cash-flow-rich but asset-light operations.

§179 and the CFPB 1071 Data Collection Era

As CFPB 1071 small business lending rule compliance ramps up, lender underwriting visibility into your equipment finance applications increases. Aggressive §179 strategies that create NOLs reduce reported taxable income — which can affect debt service coverage ratio calculations for the next equipment loan you apply for. Plan multi-year capex against the documented income story you want underwriters to see, not just the current-year tax bill. Federal Reserve household financial data shows credit-access constraints are tightening; underwriting matters.

§179 With Section 199A QBI Considerations

For pass-through entities (S-corps, partnerships, sole props), the §179 deduction reduces qualified business income (QBI), which can reduce the §199A 20% QBI deduction. Operators near the QBI phase-in thresholds ($383,900 MFJ in 2026 inflation-adjusted) face a complex optimization where §179 dollars and QBI dollars compete. The tax community consensus in operator forums and CPA practitioner discussions is to model both scenarios — max §179 vs partial §179 preserving QBI — before electing.

§179 in Multi-Entity Structures

If you operate through multiple pass-through entities (Holdco + multiple Opcos, sister LLCs, brother-sister structures), the §179 dollar limit applies at both the entity and individual taxpayer level. A taxpayer who owns three S-corps each electing $1M of §179 doesn't get $3M of §179 deduction on the personal return — the $2.56M cap binds at the individual level. Equally important: equipment transferred between commonly-owned entities triggers related-party disallowance under §267. The Tax Adviser and AICPA practice resources document the structuring patterns that preserve §179 eligibility across affiliated entities.
