Factories and other businesses that buy new equipment or build production facilities can now write off the entire purchase price in the year they acquire it, thanks to a restored 100 percent first-year depreciation deduction signed into law as part of the One Big Beautiful Bill Act. The provision, which applies to eligible property acquired after January 19, 2025, represents one of the largest business-tax changes in the 119th Congress’s reconciliation package. While supporters say the break will drive domestic manufacturing investment, critics argue it will deliver outsized benefits to the largest corporations at a steep cost to federal revenue.
Full First-Year Write-Off Returns for Equipment Buyers
The core mechanic is straightforward: instead of spreading the cost of a new machine, vehicle, or factory component across multiple tax years through standard depreciation schedules, qualifying businesses can deduct 100 percent of the cost in the first year. The Internal Revenue Service has outlined this renewed bonus depreciation in its summary of business-focused provisions, making clear that the write-off is available for a broad range of depreciable property. That single-year deduction had been phasing down since 2023 under the original terms of the 2017 Tax Cuts and Jobs Act, dropping from 100 percent to 80 percent and then 60 percent. The One Big Beautiful Bill reversed that decline and locked the deduction back at 100 percent on a permanent basis, a significant shift from the temporary structure that preceded it and a departure from the typical pattern of short-lived “extender” tax breaks.
The Treasury Department and the IRS formalized the rules through official guidance designated IR-2026-06, confirming that the permanent 100 percent additional first-year depreciation applies to eligible depreciable property acquired after January 19, 2025. In that guidance, available in the IRS’s release on the additional first-year deduction, the agencies clarify that both the acquisition date and the placed-in-service date matter for determining eligibility. That effective date means companies that purchased qualifying assets earlier this year can already claim the full deduction on their next tax filing, creating an immediate cash-flow benefit for businesses that had been waiting for clarity before committing capital. For industries with long lead times on equipment orders, such as heavy manufacturing and logistics, the certainty of a permanent 100 percent rate could influence not only what they buy, but when they choose to sign contracts.
A Separate Break for Domestic Production Facilities
Beyond the restored bonus depreciation, the law introduced a distinct category called “qualified production property,” which extends accelerated write-offs to certain assets tied directly to U.S. manufacturing. Treasury and IRS issued interim guidance on this special depreciation allowance and announced upcoming proposed regulations to define eligible property more precisely, emphasizing that the new rules are meant to steer capital into domestic plants and equipment. According to that guidance, the special depreciation allowance for qualified production property applies to assets placed in service before January 1, 2031, which introduces a sunset date that differs from the permanent treatment of general bonus depreciation. Businesses planning large factory buildouts will need to track both timelines carefully to avoid missing the window for the more targeted manufacturing incentive.
The distinction matters because the two provisions serve different policy goals and planning horizons. General bonus depreciation covers a wide range of depreciable business property, from delivery trucks and office servers to warehouse racking and certain building improvements. The qualified production property category, by contrast, is designed to channel investment specifically toward domestic manufacturing capacity and related infrastructure. The Congressional Research Service’s analysis of the reconciliation vehicle that became H.R. 1 notes that depreciation-related changes formed a central element of the bill’s economic strategy, particularly for capital-intensive sectors. For a factory owner weighing whether to expand a production line, the practical result is two overlapping but distinct paths to faster tax relief on capital spending, one broad and permanent, the other narrower but time-limited and potentially more generous for qualifying projects.
Who Benefits Most: Small Shops vs. Large Corporations
The political fight over the provision centers on distribution. A small machine shop buying a $200,000 CNC lathe gets the same percentage deduction as a multinational corporation investing billions in a new semiconductor fabrication plant. But the absolute dollar value of the tax savings scales with the size of the investment, which means the largest capital spenders capture the largest share of the benefit. Senator Elizabeth Warren, a Massachusetts Democrat, published analysis drawing on Joint Committee on Taxation projections that put a sharp number on the disparity. According to her office’s summary, JCT data showed $16 billion in retroactive benefits flowing to corporations for the 2025 and 2026 tax years, a figure her staff characterized as a giant handout to the wealthiest corporations rather than a narrowly tailored manufacturing incentive.
That framing highlights a tension the law’s supporters have not fully addressed. Proponents argue that faster write-offs reduce the after-tax cost of investment, which should encourage more factory construction, equipment purchases, and hiring, especially in sectors facing global competition. The logic tracks in theory: if a company recovers its capital outlay sooner, it can reinvest sooner, potentially compounding growth. But the JCT projections cited by Warren’s office suggest a large share of the near-term revenue loss comes from retroactive claims on equipment already purchased, not from new spending the provision induced. If companies were going to buy the equipment regardless, the deduction functions less as an incentive and more as a windfall. No publicly available IRS data yet breaks down projected uptake by firm size, leaving the distributional question partially unresolved and fueling calls from some lawmakers for future refinements that would tilt more of the benefit toward smaller manufacturers.
Practical Steps for Businesses Filing This Year
For companies preparing tax returns now, the immediate question is eligibility and documentation. The IRS has set up online tools to help filers determine whether their assets qualify, including an account lookup portal that lets taxpayers check balances and recent payments. While that tool does not itself decide depreciation treatment, it can help businesses verify that amended returns or carrybacks tied to bonus depreciation have been processed correctly. The January 19, 2025 acquisition date is the key statutory threshold: property bought or placed in service before that date does not qualify for the restored 100 percent rate and remains subject to the phase-down percentages that applied at the time of purchase. Taxpayers will need invoices, contracts, and service records to substantiate when the property was acquired and placed in service, especially in audits where timing can determine whether a full or partial deduction is allowed.
Professional guidance may be particularly important this filing season, as the interaction between permanent bonus depreciation, the temporary manufacturing allowance, and other cost-recovery rules can be complex. The IRS maintains a separate gateway for practitioners through its tax professional services page, which aggregates e-services, transcripts, and secure messaging that advisers use to manage client accounts. Businesses that handle their own filings can also consult the agency’s broader online business resources to review publications, forms, and FAQs related to depreciation and expensing. Together with the formal guidance in IR-2026-06 and the forthcoming regulations on qualified production property, these tools form the practical backbone of implementation, translating a high-profile political deal into the line-by-line calculations that will shape corporate tax bills for years to come.
