If you run a manufacturing business, the tax landscape just changed dramatically in your favor. The One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025, is the most significant overhaul of U.S. business tax policy since the 2017 Tax Cuts and Jobs Act — and according to the Tax Foundation, manufacturers stand to benefit more than any other industry, with corporations in manufacturing expected to see the largest reduction in tax liability as a share of value added in 2026. That's not a coincidence. The law was explicitly designed to reward companies that make things. If you're planning to buy equipment, build facilities, invest in R&D, or finance expansion, this legislation changes the math on nearly every major financial decision you'll face this year. This blog breaks down the key provisions, what they mean for your bottom line, and how to position your business to capture every dollar of savings available to you.
What Is the One Big Beautiful Bill Act — and Why Should Manufacturers Pay Attention?
The OBBBA is sweeping federal tax legislation passed through budget reconciliation and signed into law on Independence Day 2025. It makes several critical provisions of the 2017 Tax Cuts and Jobs Act permanent — provisions that were set to expire or phase out — and adds new incentives specifically targeted at domestic production.
For service businesses, the law is helpful. For manufacturers, it's a game-changer. The biggest wins — 100% bonus depreciation, immediate R&D expensing, a more generous interest deduction, and a new facility write-off — all apply directly to how manufacturing businesses invest, borrow, and operate.
The reason manufacturing benefits more than other sectors is straightforward: these provisions reward capital investment in physical assets. Every new machine, every facility upgrade, every process improvement your business makes is now treated more favorably under the tax code than it has been in years. If you've been holding back on capital decisions while waiting for more certainty, that wait is over.
100% Bonus Depreciation Is Back — And It's Permanent
This is the headline provision for most manufacturers. Before the OBBBA, bonus depreciation — the ability to deduct the full cost of qualifying equipment in the year you put it in service — had been phasing out. It dropped to 40% in 2025 and was headed toward zero by 2027.
The OBBBA not only restores bonus depreciation to 100%, it makes it permanent. That means when you buy a new CNC machine, a conveyor system, a forklift, or manufacturing software, you can write off the entire purchase price in year one rather than depreciating it over five, seven, or fifteen years.
The practical impact is significant. Accelerating that deduction means lower taxable income now — and more cash available to reinvest in your operations. For manufacturers who've been deferring equipment purchases waiting for a better tax environment, the window is open.
One important detail: the provision applies to assets acquired after January 19, 2025. Equipment bought under contract before that date does not qualify under the new rules. If you're planning purchases, confirm the acquisition timing with your accounting advisor before you sign any contracts.

New 100% Deduction for Qualified Production Property (Facilities)
This is a brand-new provision with no prior equivalent — and it's one of the most powerful opportunities for manufacturers who are planning to build or expand facilities.
Under the OBBBA, if you start construction on a new U.S.-based manufacturing facility between January 19, 2025, and January 1, 2029, and place it in service before 2034, you can deduct 100% of the cost in the first year. Previously, commercial real estate was depreciated over 39 years. Writing that off upfront represents a massive acceleration of tax savings.
To qualify, the property must be nonresidential real estate used for "qualified production activities" — which covers manufacturing, production, and refining of tangible personal property. The original use must begin with you, meaning newly constructed facilities qualify, while the purchase of existing buildings generally does not.
If you're thinking about building a new plant, adding production space, or investing in a purpose-built facility, run the numbers with your CFO now. The tax savings on a $3 million or $10 million building — deducted immediately rather than over 39 years — can fundamentally reshape the return on investment for that project.
Immediate R&D Expensing: A Major Win for Process-Driven Manufacturers
For the past several years, manufacturers had to capitalize domestic research and development costs and amortize them over five years. For companies investing in new product development, process engineering, or tooling innovation, that created a real cash flow drag.
The OBBBA eliminates that burden. Effective for 2025 and beyond, you can now expense domestic R&D costs immediately — in the same year they're incurred. That means the full deduction hits your tax return the year you spend the money, not spread over half a decade.
There's also a catch-up opportunity. If your company had gross receipts of $31 million or less, you may be able to amend prior-year returns to recapture R&D deductions from 2022 through 2024. The deadline to file those amended returns is July 4, 2026. That's a hard deadline, and it requires advance preparation. If this applies to your business, don't wait to talk to your advisor.
For larger manufacturers, the transition rules allow you to deduct unamortized domestic R&D costs from 2022–2024 over one or two tax years — effectively front-loading deductions that were previously spread out. This is a one-time acceleration opportunity that requires an accounting method change.
The Interest Deduction Change That Every Leveraged Manufacturer Should Know
If your business carries debt — for equipment financing, working capital lines, or facility loans — this provision directly affects how much of that interest expense you can deduct.
Under prior law, the interest deduction was limited to 30% of EBIT (earnings before interest and taxes). For manufacturers with high depreciation and amortization, that was a tight ceiling that caused real disallowed interest.
The OBBBA restores the more favorable EBITDA-based calculation, effective for tax years beginning in 2025. Under the new formula, you add back depreciation and amortization before applying the 30% limit — which means a significantly larger portion of your interest expense becomes deductible.
This matters most for capital-intensive manufacturers who invest heavily in equipment, facilities, and long-lived assets. Your D&A is often substantial, so restoring it to the calculation gives you material additional deduction room. This is one of those provisions that can directly affect cash flow without requiring you to spend a single additional dollar.
If you're uncertain how this interacts with your current financing structure, an experienced fractional CFO for manufacturing can model the impact across different debt scenarios before you file.

The 20% QBI Deduction Is Now Permanent — What Pass-Through Manufacturers Need to Know
If you operate your manufacturing business as an S-Corp, LLC, or partnership, you've been benefiting from the 20% qualified business income (QBI) deduction since 2018. But it was set to expire at the end of 2025 — which created real uncertainty for business owners making long-term structural decisions.
The OBBBA makes the QBI deduction permanent. That's straightforward but significant. It means you can continue to deduct up to 20% of your qualified business income without worrying that this benefit disappears in a future tax year. For planning purposes — and for decisions like whether to remain a pass-through entity or convert to a C-Corp — this certainty changes the equation.
Manufacturers evaluating entity structure as part of succession planning, a potential sale, or capital raises now have a more stable tax environment to work from. It's worth revisiting your entity decision with a CFO who understands both the tax implications and the operational context of your business.
Understanding the difference between S-Corp and C-Corp structures is also relevant here — especially if you're weighing growth capital or investor conversations. Our breakdown of S-Corp vs. C-Corp tax implications covers this in detail.
How to Position Your Business to Capture These Benefits
Tax law changes only benefit you if you act on them. Here's how to approach the OBBBA strategically in 2026.
Step 1: Audit Your Planned Capital Investments
Review any equipment purchases, facility upgrades, or technology investments you've been considering. If they involve assets acquired after January 19, 2025, they likely qualify for 100% bonus depreciation. Prioritize projects accordingly and make sure acquisition dates are documented correctly.
Step 2: Evaluate Facility Construction Timing
If you have any plans to build or expand a production facility, check whether you can start construction before January 1, 2029. The 100% deduction for qualified production property has a hard construction start deadline. Missing it means reverting to a 39-year depreciation schedule.
Step 3: Identify Capitalizable R&D Costs From Prior Years
Work with your accounting team to identify domestic R&D expenses from 2022 through 2024 that were capitalized and amortized. If your gross receipts were under $31 million in any of those years, you may have an amended return opportunity — but you need to file by July 4, 2026.
Step 4: Recalculate Your Interest Deduction Capacity
Ask your CFO or accounting advisor to rerun your Section 163(j) calculation using the EBITDA-based formula. For many manufacturers, this will unlock previously disallowed interest deductions — generating immediate tax savings without any additional spending.
Step 5: Build Your 2026 Tax Plan Around These Provisions
Don't let this become something you discover during year-end close. The OBBBA rewards proactive planning. Work with your financial team now to model the impact of these provisions on your 2026 tax liability, cash position, and investment decisions. For context on how smart strategic capital allocation works inside a manufacturing business, it starts with understanding what the numbers look like before you deploy capital.

Frequently Asked Questions
Does the One Big Beautiful Bill Act apply to pass-through manufacturing businesses, or only C corporations?
Both. The permanent 100% bonus depreciation, R&D expensing, and the EBITDA-based interest deduction all apply to pass-through entities — S-Corps, partnerships, and LLCs — as well as C corporations. Additionally, the permanent 20% qualified business income (QBI) deduction applies exclusively to pass-through businesses. The qualified production property deduction for new facility construction is available to eligible taxpayers regardless of entity structure. If you're a pass-through manufacturer, these provisions are directly relevant to your tax situation.
We bought equipment in early 2025. Does it qualify for 100% bonus depreciation under the new law?
It depends on timing. The OBBBA applies to assets acquired after January 19, 2025. Equipment acquired on or before that date — or acquired under a binding contract signed before January 19, 2025 — is subject to the prior-law phase-down rates. If your equipment was acquired after January 19, 2025, and placed in service during 2025, you should be eligible for the full 100% deduction. Confirm the exact acquisition date and contract status with your accounting team before filing.
My manufacturing company does process engineering and custom product development. Does that count as R&D for expensing purposes?
It may. The OBBBA's immediate R&D expensing applies to domestic research and experimentation expenditures as defined under IRC Section 174. This can include costs related to developing or improving products, processes, or techniques — which often includes engineering work, prototype development, and process innovation common in manufacturing. Foreign R&D still must be capitalized and amortized over 15 years. Whether your specific activities qualify requires a review of the nature and documentation of those costs by a qualified tax advisor.
