IRS problems aren't as complicated as they look once you see the structure. I'm attorney Darrin Mish. I've represented taxpayers before the IRS for three decades — in Florida, Colorado, Texas, and internationally. Here's the plain-English breakdown.
I'm Darrin Mish. Tampa tax attorney, 32 years in, more than $100 million in IRS debt resolved. That's my resolution practice. What follows is the other side of the desk – the planning moves that keep you from ever needing it.
The One Big Beautiful Bill Act reset the clock on bonus depreciation, restoring the 100% deduction that had been phasing down since 2022. If you bought equipment, vehicles, or certain property improvements in 2026, you can now write off the full cost immediately instead of depreciating it over years. That's the headline. What matters is whether your CPA caught the nuances and whether you're making purchases that actually qualify.
What Changed Under the One Big Beautiful Bill Act
The Tax Cuts and Jobs Act of 2017 introduced 100% bonus depreciation, but Congress built in a phasedown. By 2023, the deduction dropped to 80%. In 2024, it fell to 60%. The trajectory pointed to 40% in 2025 and 20% in 2026.
The One Big Beautiful Bill Act reversed that schedule. For property placed in service after December 31, 2024, you get 100% bonus depreciation again. The phasedown is gone. This applies retroactively to assets you placed in service in 2025 and forward through at least 2026.
Most business owners heard "100% bonus depreciation is back" and stopped there. What they missed: the restoration isn't permanent unless Congress acts again, the placed-in-service date matters more than the purchase date, and not every asset qualifies just because you use it in your business.
The Placed-in-Service Requirement
You don't get bonus depreciation 2026 treatment just by signing a purchase order. The asset must be placed in service – ready and available for its intended use – during the tax year. Buy a delivery van in December 2026 but don't start using it until January 2027? That's a 2027 deduction, not 2026.
This timing issue trips up year-end planning. You see the tax benefit, rush to buy equipment in late December, then find out delivery pushes into January. The deduction moves to next year. Your tax bill stays high this year.
What Actually Qualifies for Bonus Depreciation in 2026
Section 168(k) defines qualified property. You need property with a recovery period of 20 years or less, certain computer software, water utility property, or qualified improvement property. That's the technical definition. In practice, most business equipment qualifies. Real estate usually doesn't, except for specific improvements.
Common qualifying assets include:
- Machinery and manufacturing equipment
- Computers, servers, and office technology
- Vehicles rated over 6,000 pounds GVWR
- Office furniture and fixtures
- Certain restaurant equipment
- Qualified improvement property (interior improvements to nonresidential buildings, with exceptions)
What doesn't qualify:
- Building structures themselves
- Land or land improvements
- Property you owned previously (must be new to you)
- Property acquired from related parties
- Property with a class life over 20 years
Understanding Section 168(k) requirements helps you identify which purchases make sense from a tax perspective. The rules aren't intuitive. A $70,000 SUV qualifies. The building you operate from doesn't. Interior build-out might, depending on when you placed the building in service and what the improvements are.
Qualified Improvement Property Gets Complex
Before the Tax Cuts and Jobs Act, qualified improvement property had a 39-year recovery period. Congress meant to fix that in 2017 but made a drafting error. The correction didn't come until the CARES Act in 2020, which made the change retroactive.
Now qualified improvement property has a 15-year recovery period and qualifies for bonus depreciation. That includes improvements to interior portions of nonresidential buildings placed in service after the building itself. But it excludes enlargements, elevators, escalators, and internal structural framework.
You renovate your office space. New walls, electrical, HVAC ductwork, lighting. Most of that qualifies. You add square footage? That enlargement doesn't qualify. You replace the building's core HVAC system? Probably doesn't qualify because it's part of the structural framework.
The restoration of 100% bonus depreciation makes these distinctions matter again. At 40% bonus depreciation, the error cost you money. At 100%, the error costs you more.
Bonus Depreciation vs. Section 179: When to Use Which
Section 179 lets you expense up to $1,220,000 of qualifying property in 2026, with a phase-out starting at $3,050,000 of total purchases. Bonus depreciation has no dollar limit. Both deliver immediate deductions. They're not the same tool.
| Feature | Section 179 | Bonus Depreciation |
|---|---|---|
| Maximum deduction | $1,220,000 (2026 limit) | Unlimited |
| Income limitation | Cannot exceed business taxable income | No income limitation |
| Phase-out | Begins at $3,050,000 purchases | No phase-out |
| Qualifying property | Tangible personal property, some real property | Broader – includes new and used property |
| State conformity | Varies widely by state | More states conform |
Section 179 makes sense when you want to control the deduction amount or when you're under the dollar thresholds. It doesn't help you if your business shows a loss before depreciation. The deduction can't create or increase a net operating loss.
Bonus depreciation 2026 works whether you're profitable or not. Take the full deduction, create a loss, carry that loss forward. How bonus depreciation carry forwards work becomes relevant when you're making major equipment purchases in a down year. You get the deduction now, use the loss against future profits.
The State Tax Complication Nobody Mentions
Your federal return shows 100% bonus depreciation. Your state return might not. State tax codes don't automatically adopt federal changes. Some states conform to the Internal Revenue Code as of a specific date. Some adopt changes selectively. Some don't allow bonus depreciation at all.
California, for example, has historically not conformed to federal bonus depreciation provisions. You take the deduction federally, add it back on your California return, then depreciate on the state schedule. That creates a temporary difference – lower federal tax now, higher state tax now, reversed over time.
You need to model this. A business owner in Florida (no state income tax) gets the full benefit immediately. A business owner in California gets a smaller net benefit because the state clawback reduces the value. The decision to buy equipment in December 2026 versus January 2027 carries different weight depending on where you operate.
Strategic Planning Moves for Bonus Depreciation in 2026
The restoration of 100% bonus depreciation changes year-end planning. You're not deciding between 40% now and 60% spread over time. You're deciding between 100% now and 100% next year. The question becomes: which year needs the deduction more?
If you expect higher income in 2026 than 2027:
- Accelerate purchases into 2026
- Maximize the deduction against your highest marginal rate
- Consider pulling forward planned 2027 equipment buys
If you expect higher income in 2027 than 2026:
- Defer purchases to 2027 if operationally feasible
- Save the deduction for the year with more income to shelter
- Evaluate whether current-year needs justify lower tax benefit
Most CPAs default to "buy now, take the deduction." That works when you're always profitable and rates stay constant. It doesn't work when your income fluctuates or when rate changes are coming. The bonus depreciation planning strategies you need depend on your specific situation, not generic advice.
The Election to Opt Out
You can elect out of bonus depreciation on a class-by-class basis. Why would you? Because sometimes you want the deduction spread over multiple years instead of concentrated in one.
Consider a business with $500,000 in income and $600,000 in qualifying equipment purchases. Take 100% bonus depreciation and you have a $100,000 loss. That loss carries forward, but you get no current-year benefit. Elect out of bonus depreciation, take regular depreciation over five or seven years, and you shelter income now and in future years.
The election is irrevocable. You make it on your timely filed return (including extensions). You can't change your mind later when you see how the year played out. The decision requires forecasting – how much income will you have, how stable is it, what's your marginal rate trajectory.
Real Estate and Cost Segregation in the Bonus Depreciation Era
Residential and commercial buildings depreciate over 27.5 or 39 years. You can't bonus depreciate the structure. But components of that building have shorter class lives. Cost segregation identifies those components, reclassifies them, and makes them eligible for bonus depreciation.
A cost segregation study on a $2 million commercial building might identify $400,000 of personal property and land improvements with 5-, 7-, or 15-year class lives. With 100% bonus depreciation restored, you deduct that $400,000 immediately instead of spreading it over 39 years. The tax savings hit your return now, not gradually over decades.
Real estate investors using bonus depreciation see the biggest impact from cost segregation. Buy a rental property in 2026, commission a cost segregation study, bonus depreciate the reclassified components. A property that would normally generate a small loss or break-even can generate a six-figure tax loss that shelters other income.
The Catch: Depreciation Recapture on Sale
Everything you bonus depreciate gets recaptured when you sell. Personal property recapture comes back as ordinary income, taxed at your marginal rate. That $400,000 you deducted at 37%? When you sell, it comes back at whatever your rate is then.
This isn't a reason to avoid bonus depreciation. It's a reason to plan for it. Know that the tax benefit is a timing benefit, not a permanent exclusion. You're deferring tax, not eliminating it. In many cases, that deferral is worth it – money now is worth more than money later, and your rate might be lower when you sell.
But if you're buying equipment or property you'll sell in two or three years, the recapture happens quickly. The benefit shrinks. The planning calculation changes.
What Most CPAs Miss About Bonus Depreciation in 2026
Your CPA probably mentioned that 100% bonus depreciation is back. What they might not have analyzed: whether your state conforms, whether you should elect out, how it interacts with your retirement planning, or what it means for your multi-year tax strategy.
| What CPAs Usually Do | What You Need |
|---|---|
| Apply bonus depreciation by default | Analysis of whether to elect in or out |
| Calculate federal tax savings | Model state tax impact and net benefit |
| Process current-year returns | Multi-year projection showing carry forward effects |
| Record depreciation | Strategic asset purchase timing recommendations |
The difference isn't competence. It's focus. Most CPAs are compliance-focused. They prepare returns accurately, apply the law correctly, file on time. That's valuable. It's not the same as strategic tax planning.
Strategic planning asks: should we buy this equipment in 2026 or 2027? Should we elect out of bonus depreciation to smooth income? How does this interact with our retirement contributions and our three-year income forecast? Tax planning strategies for 2026 require someone looking forward, not just backward.
Used Property and the Original Use Requirement
Bonus depreciation used to require original use – the first business use of the property had to be by you. The Tax Cuts and Jobs Act changed that for property acquired and placed in service after September 27, 2017. Now used property qualifies if it's new to you and you didn't acquire it from a related party.
You can buy a used delivery truck, used manufacturing equipment, used office furniture. As long as you didn't previously own it and didn't buy it from someone related to you, it qualifies for bonus depreciation in 2026. This expands planning options significantly.
The related party prohibition matters more than most people realize. You can't buy property from a family member, a controlled business entity, or certain other related parties and claim bonus depreciation. The IRS defines related parties broadly in Section 267(b) and Section 707(b). A corporation you own 50% of is related. Your spouse is related. Your partnership is related.
Business owners try to restructure ownership to get around this. Move the equipment to a new entity, sell it to yourself, claim the deduction. The IRS knows these games. The regulations close the loopholes. If you're considering a related-party transaction to trigger bonus depreciation, you're in planning territory that needs specialized advice.
The Alternative Minimum Tax Consideration
Corporations face a 15% corporate alternative minimum tax (CAMT) on adjusted financial statement income if average annual financial statement income exceeds $1 billion over three years. For businesses subject to CAMT, bonus depreciation creates a timing difference between book income and tax income.
Take $1 million in bonus depreciation for tax purposes. Your financial statements still show straight-line depreciation over the asset's useful life. That creates a difference. Your regular tax liability drops. Your CAMT liability might not drop as much or at all.
Most businesses reading this aren't near the $1 billion threshold. But if you're in a partnership with large partners, or if you're in a consolidated group, the CAMT calculation affects your planning. The mechanics get complex quickly. The point: bonus depreciation under the One Big Beautiful Bill Act doesn't operate in isolation from other tax provisions.
When Bonus Depreciation Doesn't Help You
Zero taxable income means zero benefit from bonus depreciation this year. You can't deduct expenses against nothing. The deduction creates a net operating loss that carries forward, but you get no immediate tax savings.
If you're already showing a loss, buying more equipment for the tax deduction doesn't help. You're making a business decision – do you need this equipment operationally? The tax benefit will come later when you have income to shelter.
Bonus depreciation provides little value when:
- Your business is unprofitable or marginally profitable
- You're in a low tax bracket (standard deduction exceeds income)
- You plan to sell the asset quickly (recapture eliminates benefit)
- Your state doesn't conform and you're in a high-tax state
- You have significant NOL carryforwards already
The planning move here is to consider Section 179 instead, which at least lets you control the deduction amount, or to elect out of bonus depreciation entirely and take regular depreciation when you have income to shelter.
Documentation Requirements Nobody Follows Until Audit
The IRS doesn't require you to file anything special to claim bonus depreciation. You report it on Form 4562, list the assets, take the deduction. Simple on the surface. Painful if you get audited and can't substantiate what you bought, when you placed it in service, and what you paid.
What you need to maintain:
- Purchase invoices showing date and amount
- Proof of payment (cancelled checks, credit card statements)
- Documentation of placed-in-service date (delivery receipts, installation records)
- For vehicles, proof of business use percentage
- For improvements, records showing the property was placed in service after the building
- For used property, documentation showing it's new to you
Most businesses keep the invoice. They don't keep the delivery confirmation. They don't document when the equipment actually became operational. Three years later, in an audit, they can't prove the placed-in-service date. The IRS disallows the deduction or moves it to a different year.
This isn't paranoia. This is pattern recognition from 32 years of seeing what breaks down under examination. Your accounting software tracks the depreciation. It doesn't track the underlying documentation. That's on you.
The 2027 Question: What Happens Next Year?
The One Big Beautiful Bill Act restored 100% bonus depreciation for property placed in service after December 31, 2024. It didn't set an end date. That means 100% bonus depreciation continues until Congress changes it again.
Congress could extend it permanently. Congress could let it phase down again. Congress could eliminate it entirely. Nobody knows. The political environment, budget priorities, and economic conditions will determine what happens.
What that means for planning: don't assume 100% bonus depreciation lasts forever, but don't panic and rush purchases because it might end tomorrow. Make business decisions based on operational needs. Use the tax benefit as a factor, not the deciding factor.
The businesses that win over time are the ones that buy equipment when they need it, structure purchases to optimize tax benefits, and don't let tax considerations override business judgment. The tax tail shouldn't wag the business dog.
Bonus depreciation 2026 gives you immediate deductions for qualifying property, but only if you understand what qualifies, when to elect in or out, and how it fits your multi-year tax strategy. Most compliance work misses those planning opportunities. Taxt builds strategic tax planning into every client relationship, with projections that show you exactly how timing and elections affect your tax liability this year and next, backed by a guarantee that the savings show up or you don't pay.
