100% Bonus Depreciation Is Back — Save Thousands This Tax Season

The Biggest Tax Break in Years Just Became Permanent

If you bought equipment, software, or vehicles for your business in the last year and haven't claimed 100% bonus depreciation, you could be leaving tens of thousands of dollars on the table. The One Big Beautiful Bill Act (OBBBA), signed into law in 2025, permanently restores 100% first-year bonus depreciation for qualifying assets — and the IRS just issued interim guidance clarifying exactly how small businesses can take advantage.

This isn't a temporary extension or a partial phase-in. It's the full deduction, permanently. And for small business owners filing 2025 returns right now or planning 2026 purchases, the timing couldn't be better.

What Changed — and Why It Matters to Your Bottom Line

Before the OBBBA, bonus depreciation was on a death spiral. Under the 2017 Tax Cuts and Jobs Act, the deduction was phasing down: 80% in 2023, 60% in 2024, 40% in 2025, and headed to zero by 2027. Small businesses were watching their most powerful tax tool disappear.

Now it's back — permanently at 100%. Here's what that means in plain English:

When you buy a qualifying asset for your business, you can deduct the entire cost in the year you put it into service. No spreading the deduction over 5, 7, or 39 years. The full amount comes off your taxable income immediately.

The Cash Flow Impact Is Massive

Let's look at what this means in real dollars:

Asset Purchase	Without Bonus Depreciation (Year 1)	With 100% Bonus Depreciation (Year 1)	Tax Savings at 24% Rate
$50,000 truck	$10,000 deduction	$50,000 deduction	$9,600
$30,000 equipment	$4,286 deduction	$30,000 deduction	$6,171
$15,000 software	$5,000 deduction	$15,000 deduction	$2,400
$100,000 buildout	$2,564 deduction	$100,000 deduction	$23,385

That $50,000 work truck you bought? Instead of deducting $10,000 per year over five years, you deduct all $50,000 in year one. At a 24% tax rate, that puts $9,600 back in your pocket this year instead of trickling in over half a decade.

What Qualifies for 100% Bonus Depreciation

Not everything qualifies, but the list is broader than most business owners realize. According to RSM's analysis of the OBBBA provisions, eligible property includes:

Definitely Qualifies

Equipment and machinery — manufacturing tools, restaurant equipment, construction gear
Computer hardware and software — servers, laptops, point-of-sale systems, off-the-shelf software
Vehicles over 6,000 lbs — work trucks, vans, SUVs used for business (subject to some limits for passenger vehicles)
Office furniture and fixtures — desks, chairs, shelving, display cases
Qualified improvement property — interior improvements to leased or owned non-residential buildings (HVAC, lighting, flooring, security systems)
Certain building components — identified through cost segregation studies as having shorter useful lives

The New Category: Qualified Production Property

The OBBBA also created a new temporary category — qualified production property — which extends bonus depreciation to certain building components used in manufacturing and production. This is a significant expansion that could benefit manufacturers, food processors, and other production-oriented small businesses.

What Doesn't Qualify

Land and land improvements (landscaping, paving in some cases)
Buildings themselves (the structure, not the interior improvements)
Property used outside the United States
Property acquired from related parties
Assets placed in service before certain qualifying dates

Important timing note: The IRS interim guidance clarifies that property must be acquired after January 19, 2025 to qualify for the restored 100% rate. Equipment ordered before that date under the old phase-down schedule may only qualify for the reduced percentage. Check with your tax preparer on the specific transition rules.

The QBI Deduction Is Now Permanent Too

While bonus depreciation grabs the headlines, the OBBBA also made the 20% Qualified Business Income (QBI) deduction permanent for pass-through entities. If you operate as an LLC, S-corp, partnership, or sole proprietorship, this is enormous.

As Bradley's OBBBA guide for small businesses explains, the QBI deduction was set to expire after 2025 — meaning pass-through business owners faced a significant tax increase starting in 2026. That cliff is now gone.

Here's how these two provisions can work together:

Bonus depreciation reduces your taxable income by the full cost of qualifying assets
QBI deduction then takes 20% off your remaining qualified business income
Combined effect: Dramatically lower tax bill and more cash staying in your business

For a small business owner with $200,000 in qualified business income who also purchased $75,000 in equipment, the combined savings could easily exceed $25,000 in a single year.

Three More OBBBA Changes You Shouldn't Miss

1. SALT Deduction Increase

The state and local tax (SALT) deduction cap rises from $10,000 to $40,000 in 2026, with annual increases through 2029. If you're in a high-tax state like California, New York, or New Jersey, this alone could save you thousands.

2. Higher 1099 Reporting Threshold

The threshold for filing 1099-NEC and 1099-MISC forms increases from $600 to $2,000. Meanwhile, the 1099-K threshold for payment platforms like PayPal and Venmo returns to $20,000 and 200 transactions. Less paperwork, fewer compliance headaches.

3. Section 179 Expansion

The Section 179 expensing limits have been increased and made permanent, giving small businesses another option for immediate deduction of qualifying purchases — with slightly different rules than bonus depreciation that may be advantageous depending on your situation.

How to Maximize Your Savings This Tax Season

Knowing about bonus depreciation is one thing. Actually capturing every dollar you're entitled to is another. Here's your action plan:

For Your 2025 Returns (Filing Now)

Inventory every asset you purchased or placed in service after January 19, 2025
Check the acquisition date — the IRS transition rules matter for assets ordered before the cutoff
Consider a cost segregation study if you own commercial property — reclassifying building components as shorter-lived assets can unlock massive deductions
Compare Section 179 vs. bonus depreciation — depending on your income level and state tax situation, one may be more beneficial than the other

For 2026 Planning

Accelerate planned purchases — if you're considering equipment, vehicles, or technology upgrades, buying sooner means deducting sooner
Model the cash flow impact — understand exactly how much you'll save and when, so you can reinvest strategically
Track your estimated tax payments — large deductions change your quarterly estimated tax obligations
Document everything — keep invoices, purchase orders, and records of when assets were placed in service

The Visibility Problem

Here's where most small businesses stumble: they don't have real-time visibility into how tax decisions affect their cash flow. You buy a $60,000 piece of equipment, claim the bonus depreciation, but don't account for how that changes your quarterly tax payments, working capital, or borrowing needs.

This is exactly the kind of scenario where an AI-powered financial tool pays for itself. CFO bot connects directly to your QuickBooks, Xero, or Stripe accounts and models how major purchases and deductions ripple through your entire financial picture. Instead of waiting until April to discover you overpaid estimated taxes — or underpaid and owe penalties — you see the impact in real time.

Need to ask "What happens to my cash flow if I buy $80,000 in equipment this quarter and claim bonus depreciation?" You get an instant, data-backed answer from an AI CFO available 24/7 via chat — not a $300/hour consultation two weeks from now. And when questions get complex enough to need a human expert, the CPA backstop ensures you get professional-grade answers without the full-time price tag.

Don't Let This Opportunity Pass You By

The OBBBA represents the most business-friendly tax environment in years. Between permanent 100% bonus depreciation, the QBI deduction lock-in, and expanded SALT caps, small businesses have more tools than ever to reduce their tax burden and keep cash flowing.

But here's the catch: these deductions don't claim themselves. You need to know what qualifies, time your purchases strategically, and model the downstream effects on your cash flow and tax obligations. The businesses that will benefit most aren't just the ones who know about these changes — they're the ones with the financial infrastructure to act on them quickly and confidently.

The difference between paying $40,000 in taxes and $25,000 in taxes might come down to whether you had the right financial visibility when it mattered.
