Treasury Seeks Public Comment on New Bonus Depreciation Rules for Production Property

WASHINGTON — The U.S. Department of the Treasury and the Internal Revenue Service have announced they are seeking public comments on forthcoming regulations that will define key aspects of the 100% bonus depreciation allowance for qualified production property. The request, detailed in Notice 2026-16, invites businesses and tax professionals to weigh in on the standards for property used in manufacturing, production, and refining before a deadline of April 20, 2026. This request for public input is a critical, if often overlooked, part of the regulatory process. For businesses planning significant capital outlays in the coming years, this is a direct opportunity to influence rules that will have a tangible impact on their bottom line and investment strategy. Bonus depreciation, also known as the additional first-year depreciation deduction under section 168(k) of the Internal Revenue Code, allows businesses to immediately deduct a large percentage of the purchase price of eligible assets, rather than writing them off over many years. This tax incentive is designed to encourage capital spending by reducing the after-tax cost of equipment, machinery, and other qualified property. The Tax Cuts and Jobs Act of 2017 (TCJA) initially set the bonus depreciation rate at 100% but included a gradual phase-down. However, the recently enacted "One Big Beautiful Bill Act" (OBBBA) reinstated the 100% rate for qualified property acquired and placed in service after January 19, 2025. OBBBA also created a new category of eligible assets known as qualified production property (QPP) under IRC Section 168(n). Notice 2026-16 provides interim guidance on this new category, which taxpayers can rely on immediately, but it also highlights several areas where the agencies need more specific feedback before finalizing the rules. The request for comments centers on the definitions and standards that will determine which assets qualify for the powerful 100% deduction. According to the notice, Treasury and the IRS are specifically looking for input on defining terms such as "manufacturing," "production," and "refining." They are also seeking examples of reasonable methods for allocating a property's cost basis when a single asset is used for both eligible and ineligible activities. One of the most significant areas of uncertainty involves the definition of an "integrated facility." The agencies are asking for clarification on whether tracts of land should be considered "contiguous" if they are separated by a road, stream, or railroad. The determination could have major financial consequences for companies with large, multi-parcel industrial campuses, potentially allowing or disallowing millions of dollars in accelerated deductions. The ambiguity around terms like "contiguous" or how to allocate costs is precisely where tax planning can become complex. We often see businesses either miss out on significant deductions due to uncertainty or face challenges during audits because of aggressive interpretations. Navigating these gray areas requires a deep understanding of both the current interim guidance and the direction the final regulations are likely to take. This is a core part of the tax preparation and compliance services C&S Finance Group LLC provides at csfinancegroup.com, ensuring clients can maximize legitimate tax benefits without taking on unnecessary risk. While the final regulations are being developed, Notice 2026-16 offers a temporary framework. It confirms that many existing rules from Treasury Regulation Section 1.168(k)-2 will carry over. This includes the standards for determining when property is acquired and placed in service. For purchased property, the acquisition date is generally when a written binding contract is executed. For self-constructed property—assets a business builds for its own use—the acquisition and placed-in-service timing tests are crucial for eligibility. To qualify for bonus depreciation, an asset must generally have a useful life of 20 years or less. This includes vehicles, machinery, equipment, and computer software. The TCJA also expanded eligibility to include certain used property, provided it meets several requirements, such as not having been previously used by the taxpayer and not being acquired from a related party. Qualified improvement property, which covers certain interior upgrades to nonresidential buildings, is also eligible. For small and mid-sized businesses in the manufacturing and industrial sectors, the outcome of this comment period is particularly important. The ability to fully expense a major equipment purchase in the first year can significantly improve cash flow, freeing up capital for hiring, expansion, or further investment. Clear, practical rules reduce compliance costs and provide the certainty needed to move forward with large-scale projects. Our view is that businesses in the manufacturing and production sectors should seriously consider submitting comments, either directly or through their industry associations. Practical, real-world examples of how these definitions would apply on the ground are invaluable to regulators and can lead to more workable final rules for everyone. Following the April 20, 2026, deadline, Treasury and the IRS will review the submitted comments as they draft the proposed regulations. Businesses and tax advisors will be watching closely for the release of those proposed rules, which will provide the next level of clarity on how the permanent 100% bonus depreciation for production property will be administered.
