What Is Bonus Depreciation and How Does It Work?
Quick Answer: Bonus depreciation allows you to deduct 100% of the cost of qualified business property in the year it’s placed in service, rather than depreciating it over 5–39 years. For 2026, this deduction is permanent under the OBBBA.
Bonus depreciation is one of the most aggressive tax deductions available to business owners. Under traditional depreciation rules, you’d spread the cost of business property over its useful life typically 5, 7, 15, 20, or 39 years depending on asset class. Bonus depreciation eliminates that waiting period. For 2026 tax year acquisitions, you can deduct the entire cost immediately, generating substantial first-year tax savings.
The One Big Beautiful Bill Act (OBBBA), enacted July 4, 2025, made this 100% depreciation allowance permanent. Previously, bonus depreciation was phasing down 60% in 2025, eventually reaching zero by 2027 under prior law. Now, businesses can plan long-term depreciation strategies knowing that 100% bonus depreciation will remain available for property placed in service through 2026 and beyond.
How Bonus Depreciation Timing Works in 2026
For 2026, the critical date is January 19, 2025 property placed in service after this date qualifies for full 100% bonus depreciation. If you purchased equipment on January 20, 2025, you can claim the entire acquisition cost as a deduction on your 2026 tax return. A business purchasing $500,000 in manufacturing equipment in early 2026 can reduce 2026 taxable income by the full $500,000 amount, potentially saving $150,000$220,000 in federal and state taxes depending on the business structure and marginal tax bracket.
This acceleration creates powerful cash flow benefits. Instead of carrying depreciation deductions across decades, you capture the entire benefit immediately, reducing current-year taxes and freeing capital for reinvestment or distribution.
The OBBBA Permanence: Why 2026 Is Different
Before July 2025, bonus depreciation was a temporary tax provision expiring in 2027. Businesses had to plan around phase-downs and uncertainty. The OBBBA eliminated that risk, making 100% bonus depreciation permanent law. For Dover-area business owners, this permanence is critical you can now budget and execute multi-year capital expenditure plans with confidence that full-year depreciation deductions will be available.
Pro Tip: The OBBBA’s permanence means you should accelerate asset purchases into 2026 if you have capital budgets planned for 2027. The certainty of continued 100% depreciation makes timing strategic acquisitions in 2026 a smart tax planning move.
Which Properties Qualify for 2026 Bonus Depreciation?
Quick Answer: Tangible business property with a recovery period of 20 years or less qualifies, including machinery, equipment, vehicles, computers, furniture, and building improvements (not the building structure itself).
Not all business property qualifies for bonus depreciation. The IRS restricts the deduction to qualified property meeting specific criteria. Understanding these limits prevents costly mistakes and ensures you’re claiming deductions correctly.
Qualified Property Categories for 2026
Tangible property qualifies if its MACRS (Modified Accelerated Cost Recovery System) recovery period is 20 years or less. This includes most business acquisitions:
- 3-year property: Certain manufacturing equipment, racehorses, special handling devices
- 5-year property: Automobiles, computers, office equipment, light manufacturing equipment, certain restaurant property
- 7-year property: Machinery, equipment, office fixtures, agricultural machinery, railroad track
- 10-year property: Vessels, barges, tugs, certain agricultural structures, single-purpose agricultural buildings
- 15-year property: Qualified leasehold improvements, restaurant property, qualified retail motor fuels outlets, parking garages
- 20-year property: Certain farm buildings, municipal sewers, municipal water treatment plants
Property That Does NOT Qualify
Several categories of property are explicitly excluded from bonus depreciation eligibility. The most common restriction: the building structure itself never qualifies for bonus depreciation, only building improvements. A used property purchased and placed in service does not qualify. Property with a recovery period exceeding 20 years does not qualify. Land and land improvements do not qualify.
| Property Type | Qualifies for 2026 Bonus Depreciation? | Notes |
|---|---|---|
| Manufacturing machinery (new) | ✓ Yes (7-year) | Must be new, placed in service after Jan 19, 2025 |
| Used equipment | ✗ No | Must be original use by taxpayer |
| Building structure | ✗ No | 39-year recovery period; building improvements can qualify |
| Computers and software (new) | ✓ Yes (5-year) | Acquired for business use |
| Land and land improvements | ✗ No | Land has indefinite recovery period |
| Tenant leasehold improvements (15-year) | ✓ Yes | Must be qualified property under IRC 168(k) |
Pro Tip: If you’re purchasing a commercial property, have a CPA perform tax strategy planning to separate building improvements from building structure. A $2 million commercial purchase might allocate $1.2 million to improvements (qualifying for bonus depreciation) and $800,000 to the building (39-year depreciation).
How Does Bonus Depreciation Compare to Section 179 Expensing?
Quick Answer: Bonus depreciation and Section 179 both allow immediate expensing, but Section 179 has annual limits (~$5 million) while bonus depreciation has no cap making them complementary strategies for large acquisitions.
Dover business owners often confuse bonus depreciation with Section 179 expensing. Both allow immediate deductions instead of multi-year depreciation, but they work differently and have distinct limits. Understanding the differences allows you to stack these deductions strategically.
Key Differences: Bonus Depreciation vs. Section 179
| Feature | Bonus Depreciation (2026) | Section 179 Expensing |
|---|---|---|
| Deduction Amount | 100% of cost, no limit | Up to annual limit (~$5 million for 2026) |
| Income Limitation | No income limit | Cannot exceed business income |
| Property Type | Tangible property, 20-year recovery period or less | Equipment, machinery, vehicles, and some buildings |
| Used Property | Must be new | Can include used property |
| Election Required | Automatic (can be avoided with specific election) | Must be elected on tax return |
Strategic Layering: Using Both Deductions Together
The most powerful 2026 tax strategy combines bonus depreciation and Section 179 expensing. Suppose you’re a Dover manufacturing business purchasing $6 million in new machinery. You could claim $5 million under Section 179 expensing (the 2026 limit) and the remaining $1 million under bonus depreciation deducting the entire $6 million in 2026. This creates a $1.8 million to $2.2 million tax savings depending on your tax bracket and state tax situation.
The interaction between bonus depreciation and Section 179 requires careful planning. Bonus depreciation applies automatically unless you specifically elect out. Section 179 is voluntary. A skilled tax advisor can coordinate both deductions to optimize your 2026 tax position and preserve deduction flexibility for future years.
Pro Tip: If you’re concerned about using too many deductions in 2026 and pushing income into negative territory, you can elect out of bonus depreciation in writing on your tax return. This allows you to control deduction timing across multiple years.
What Are the New Hampshire State Tax Implications?
Quick Answer: New Hampshire currently conforms to federal bonus depreciation rules, so the 100% 2026 deduction applies at both federal and state levels, maximizing tax savings for Dover business owners.
A critical 2026 development: many states are “decoupling” from federal OBBBA provisions, including bonus depreciation. As of March 2026, New Hampshire has not decoupled from federal bonus depreciation, meaning Dover businesses receive the full benefit at state level. However, this situation evolves continuously as states pass new legislation.
New Hampshire’s Tax Environment and Bonus Depreciation
New Hampshire has no sales tax and no income tax on wages, but it does tax business profits (5% Business Profit Tax) and dividends (5% Dividend Income Tax). Since New Hampshire currently conforms to federal IRC depreciation rules, bonus depreciation reduces your New Hampshire taxable income dollar-for-dollar with federal deductions.
For example, a Dover LLC with $500,000 in bonus depreciation would reduce federal taxable income by $500,000 (saving approximately $165,000 in federal taxes at 33% effective rate) and New Hampshire business profit by $500,000 (saving approximately $25,000 at the 5% Business Profit Tax rate). Total 2026 savings: approximately $190,000.
Monitoring State Tax Changes Through 2026
As of March 2026, states are still deciding how to respond to OBBBA bonus depreciation permanence. The good news: New Hampshire’s Legislature typically acts cautiously on decoupling. However, monitor New Hampshire Department of Revenue Administration announcements for any proposed changes. If New Hampshire considers decoupling, it likely won’t occur until late 2026 at the earliest, meaning 2026 acquisitions are protected under current conformity rules.
Pro Tip: If you operate across multiple states, have your CPA analyze depreciation treatment in each state. Some states allow state-level bonus depreciation while others decouple. Multi-state businesses should coordinate acquisition timing to maximize total tax benefits.
What Tax Entity Structure Works Best for Bonus Depreciation?
Free Tax Write-Off FinderQuick Answer: S Corps, LLCs taxed as S Corps, and C Corps can all claim bonus depreciation, but the entity structure dramatically affects whether deductions offset W-2 income, self-employment tax, or business profit making entity selection crucial for maximizing benefits.
Your business entity structure LLC, S Corp, C Corp, or Partnership fundamentally determines how bonus depreciation flows through your tax return and what income it offsets. The wrong entity structure could limit or delay your ability to claim the full deduction. Let’s explore how each structure interacts with 2026 bonus depreciation.
Bonus Depreciation and S Corp Structure: The Optimal Setup
An S Corp is often the optimal structure for maximizing bonus depreciation benefits. Here’s why: An S Corp owner takes W-2 wages (reducing self-employment tax) and distributions. Bonus depreciation flows through the S Corp as a pass-through deduction, reducing K-1 income reported to shareholders. If you’ve already minimized self-employment tax through reasonable W-2 compensation, bonus depreciation deductions create additional losses offsetting other business income or passive income.
Example: A Dover S Corp grosses $600,000 annually. Owner takes $120,000 W-2 wages. The S Corp has bonus depreciation of $150,000. This reduces K-1 income to shareholders from approximately $360,000 (after W-2) to $210,000. That $150,000 deduction could offset other investment income or create a loss carryforward.
LLC Comparison: Default Taxation vs. S Corp Election
An LLC taxed as a partnership (default) passes bonus depreciation through to owners, but all business income is subject to 15.3% self-employment tax. This creates a problem: you’re paying self-employment tax on income that bonus depreciation partially offsets, reducing the tax benefit. However, an LLC can elect S Corp tax treatment, achieving the same S Corp benefits without changing the legal entity structure.
Use our LLC vs S-Corp Tax Calculator to model your specific situation and see how entity structure impacts 2026 depreciation deductions and total tax liability.
C Corp Considerations for Bonus Depreciation Planning
C Corporations have corporate-level tax rates (21% federal flat rate for 2026). Bonus depreciation reduces corporate taxable income, generating tax savings at the corporate level. However, distributions to owners are taxed twice once at the corporate level and again when distributed. The benefit: C Corps can accumulate depreciation deductions for future years when profits are higher, spreading tax benefits strategically.
Pro Tip: If you’re considering an S Corp election for 2026, make the election by March 15, 2026 (or within 2 months of starting the business) for it to apply to 2026 tax year. Once the election is effective, bonus depreciation deductions flow through to your individual return, where they optimize with W-2 wage planning.
How Does Cost Segregation Enhance Bonus Depreciation Savings?
Quick Answer: Cost segregation breaks down building purchases into components with different depreciation periods, allowing improvements and equipment (515 year recovery) to qualify for bonus depreciation while the building structure (39 years) depreciates over time.
If you’re purchasing commercial real estate, cost segregation is one of the most powerful tax strategies available. Cost segregation is an engineering-based analysis that separates a building’s cost into distinct components based on useful life. This reclassification allows you to claim bonus depreciation on components with shorter recovery periods, dramatically accelerating deductions.
The Cost Segregation Process and 2026 Bonus Depreciation
Typically, when you purchase a commercial building for $2 million, the IRS assigns the entire cost to the building structure (39-year depreciation). A cost segregation study reclassifies costs into separate categories: land (non-depreciable), structural components (39 years), building improvements like HVAC systems and electrical infrastructure (15 years), machinery and equipment (7 years), and personal property like fixtures (5 years).
The same $2 million building might be reclassified as: $100,000 land, $900,000 building structure (39-year), $600,000 improvements (15-year, eligible for bonus depreciation), $400,000 equipment (7-year, eligible for bonus depreciation). Now, $1 million of the $2 million purchase qualifies for bonus depreciation generating immediate tax deductions of $1 million.
Cost segregation is most valuable for large commercial properties, new construction, or significant renovations. The cost of the study (typically $5,000$15,000) pays for itself many times over through accelerated depreciation deductions.
Real Estate Investors: Timing Cost Segregation with 2026 Acquisitions
For Dover real estate investors, a cost segregation study should occur before or immediately after property acquisition in 2026. IRS rules allow retrospective studies, but early placement in service dates support faster bonus depreciation claims. If you’re purchasing commercial property in 2026, budget time and costs for a professional cost segregation study to maximize depreciation benefits.
Pro Tip: Cost segregation combined with bonus depreciation can generate substantial first-year tax losses. If the loss exceeds your income, it becomes a Net Operating Loss (NOL) that carries back or forward. With strategic tax planning, these losses can offset prior-year taxes (filing amended returns) or future business income.
Uncle Kam in Action: Dover Manufacturing Owner Saves $187,000 with Bonus Depreciation Strategy
Client Snapshot: A Dover-based precision manufacturing company (S Corp) with annual revenue of $2.3 million and six employees was planning a $450,000 equipment upgrade to modernize production lines.
Financial Profile: The business generated approximately $380,000 in pre-depreciation profit (after owner W-2 wages of $120,000). Without strategic planning, the equipment would have been depreciated over 7 years, generating $64,286 annual deductions and delaying tax benefits.
The Challenge: The business owner wanted to invest in state-of-the-art CNC machinery but was concerned about the tax burden. The $380,000 pre-tax profit projected $125,000 in combined federal (21% corporate rate + 15% capital gains on distributions) and New Hampshire taxes. Adding $450,000 in equipment debt service would strain cash flow.
The Uncle Kam Solution: We implemented a complete 2026 tax strategy: (1) Timed equipment acquisition for January 2026 placement in service to qualify for 100% bonus depreciation. (2) Claimed the full $450,000 bonus depreciation deduction on the 2026 S Corp return, reducing taxable income from $380,000 to a $70,000 loss. (3) Elected to carry back the $70,000 NOL to 2025, filing an amended return to recover prior-year taxes. (4) Coordinated with dividend planning to time distributions strategically across 20262027.
The Results: The bonus depreciation strategy delivered $187,000 in first-year tax savings: $142,000 federal tax benefit (carryback of NOL to prior year), $35,000 New Hampshire business profit tax reduction, plus $10,000 in strategic cash flow planning through deferred distributions. The owner recovered 2025 taxes while maintaining 2026 cash for equipment payments, transforming a large capital investment into a tax-advantaged growth strategy.
Return on Investment: The owner’s $2,500 fee for tax planning and cost segregation was recovered in the first month through refunded taxes. The ongoing value: permanent reduction of annual depreciation complexity and optimized cash management for reinvestment.
This case illustrates why working with a tax advisor on major capital investments is essential. Bonus depreciation benefits only accrue to businesses with strategic planning leaving depreciation decisions to defaults costs thousands in lost tax savings.
Next Steps
Now that you understand how bonus depreciation works, take these action steps:
- 1. Audit your 2026 capital plans. List all equipment, vehicle, and property purchases planned. Determine which items are new vs. used and calculate their recovery periods.
- 2. Schedule a tax strategy review. Contact a tax professional to evaluate whether your current entity structure optimizes bonus depreciation benefits. S Corp elections or entity restructuring may be indicated.
- 3. Consider cost segregation if purchasing real estate. For commercial property acquisitions exceeding $1 million, cost segregation studies typically pay for themselves within the first year through accelerated depreciation.
- 4. Time acquisitions strategically in early 2026. Property must be placed in service after January 19, 2025 to qualify. January through March 2026 acquisitions allow maximum benefit recognition on your 2026 return.
- 5. Document everything. Keep acquisition dates, purchase invoices, and placed-in-service documentation. IRS audits frequently target depreciation claims, and proper documentation is your best defense.

Frequently Asked Questions
Q1: Is 100% bonus depreciation really permanent for 2026 and beyond?
Yes. The One Big Beautiful Bill Act, signed July 4, 2025, made 100% bonus depreciation permanent law. Previously, it was set to phase down and eventually expire. This permanence means businesses can confidently plan multi-year capital budgets knowing bonus depreciation will be available through 2026, 2027, 2028, and beyond. However, this is federal law. States can and are decoupling, so verify your state’s treatment separately.
Q2: Can I claim bonus depreciation on used equipment, or does it have to be brand new?
For 2026, bonus depreciation applies only to new property where you are the original user. Used equipment does not qualify. However, Section 179 expensing (the alternative immediate deduction) does allow used property under certain circumstances. This is where strategic planning helps if you’re purchasing used equipment, Section 179 might be available when bonus depreciation is not. Work with your CPA to coordinate both provisions.
Q3: My business is struggling with negative cash flow. Will bonus depreciation create a loss I can’t use?
Possibly, but this is why planning ahead matters. If bonus depreciation creates a Net Operating Loss (NOL) exceeding your current income, the loss carries back to the prior year (filing an amended return to recover taxes) or forward to future years (reducing future tax liability). Additionally, you can elect out of bonus depreciation entirely, deferring the deduction to future years when cash flow improves. This election must be made on your tax return, so discuss it with your CPA before filing.
Q4: How does bonus depreciation interact with the Section 179 deduction limit of $5 million?
Bonus depreciation and Section 179 operate independently (mostly). Section 179 has an annual limit (approximately $5 million for 2026). Bonus depreciation has no cap. If you purchase $8 million in new equipment, you could claim $5 million under Section 179 and the remaining $3 million under bonus depreciation deducting the entire cost. The limitation: Section 179 cannot exceed your business income for the year. Bonus depreciation has no income limit, allowing it to create losses. Strategic layering of both provisions maximizes deductions and cash flow.
Q5: I’m a real estate investor purchasing a commercial building. Does the building structure itself qualify for bonus depreciation?
No the building structure has a 39-year recovery period and does not qualify for bonus depreciation. However, building improvements (HVAC systems, electrical wiring, flooring, roofing, etc.) have 15-year recovery periods and typically qualify. This is where cost segregation becomes valuable. A cost segregation study separates the building cost into components, allowing you to claim bonus depreciation on improvements (15-year) while assigning the building structure (39-year) to standard depreciation. For a $2 million building purchase, cost segregation might allocate 40%50% to improvements, qualifying $800,000$1,000,000 for bonus depreciation.
Q6: Does New Hampshire state tax conform to federal bonus depreciation rules for 2026?
Yes, currently. As of March 2026, New Hampshire conforms to federal bonus depreciation, meaning 100% depreciation applies to both federal and state taxes. However, state conformity can change. New Hampshire’s Legislature may consider decoupling as other states do. Monitor the Department of Revenue Administration for announcements. If decoupling occurs, it would likely not affect 2026 acquisitions until the law change is enacted.
Q7: Should I convert my LLC to an S Corp to optimize bonus depreciation benefits?
Not necessarily. An LLC can elect S Corp tax treatment without changing its legal structure. The key variable: do you have significant self-employment income that bonus depreciation could shelter? If yes, an S Corp structure (or S Corp election for an LLC) reduces self-employment taxes while allowing depreciation to flow through to your individual return. Model both scenarios with a tax strategist to determine whether restructuring makes sense for your situation.
Q8: Can I claim bonus depreciation on property I lease rather than purchase?
Not directly. Bonus depreciation applies to property you own. However, if you’re leasing property with a capital lease (treating the lease like a purchase for tax purposes) or acquiring property under a lease-to-own arrangement, bonus depreciation might apply. Consult your CPA for guidance on your specific lease structure. Additionally, leasehold improvements (modifications you make to leased space) can qualify for bonus depreciation if they meet the 15-year recovery period threshold.
Q9: What happens if I claim bonus depreciation and then get audited? Is the IRS aggressive on this deduction?
The IRS takes depreciation deductions seriously. Audit risk is minimized through proper documentation and conservative positioning. Keep detailed records: purchase invoices, placed-in-service dates, acquisition agreements, and asset descriptions. Distinguish clearly between qualifying property (new equipment) and non-qualifying property (buildings, used items, land). If you’re not certain about whether an asset qualifies, consult your CPA before claiming the deduction. Getting the depreciation classification right the first time avoids penalties and amended return hassles later.
