New IRS Guidance on Special Depreciation Rules Explained

Investing in new facilities or expanding production capacity can be one of the most significant financial decisions a business makes. Recent tax changes may make those investments far more attractive.

The Treasury Department and the Internal Revenue Service (IRS) recently released Notice 2026-16, interim guidance that allows businesses to deduct a much larger portion of certain property costs upfront. The guidance focuses on qualified production property and is part of broader tax changes introduced by the One Big Beautiful Bill Act.

For small business owners considering facility upgrades or production expansion, this development could create meaningful tax savings. By accelerating depreciation deductions, businesses may reduce taxable income in the year they invest, improving cash flow and freeing up capital for growth.

Understanding the rule and its requirements is important. Like many tax changes, the opportunity is significant, but the details matter. Use this guide to better understand the special depreciation rules and how they may apply to your business operations. 

Key Highlights

• Businesses may be able to deduct up to 100% of a property’s unadjusted basis in the year it is placed in service.

• The rule generally applies to qualifying property placed in service after July 4, 2025, and before January 1, 2031.

• Eligible property typically includes nonresidential buildings used in manufacturing, agriculture, chemical production, or refining.

The IRS Issues New Guidance on Special Depreciation Rules

The IRS recently issued Notice 2026-16, which provides interim instructions on how businesses can claim a special depreciation allowance for qualified production property. The announcement, detailed in the official IRS release on IRS guidance on qualified production property, outlines how the new rule works and how taxpayers can apply it. Formal regulations are still under development.

The guidance stems from provisions included in the One Big Beautiful Bill, a major piece of tax legislation passed in 2025 designed to stimulate domestic investment and economic growth. The legislation restored several pro-investment tax policies and introduced new expensing rules that encourage businesses to build or expand production facilities.

According to the analysis of these One Big Beautiful Bill business tax changes, the law reinstates 100% bonus depreciation rules and expands expensing opportunities for certain types of capital investment. The new production property rule is one of those provisions.

The IRS guidance clarifies how businesses can begin applying the rule immediately, even though additional regulations are expected. Until formal regulations are issued, taxpayers may rely on this interim guidance to determine eligibility and claim the deduction.

For many businesses, this means several new opportunities to accelerate deductions on major property investments. 

What Is the Special Depreciation Allowance?

To understand the IRS depreciation rules for manufacturing facilities, defining qualified production property first will help.

In general, depreciation allows businesses to recover the cost of property used in their operations over time. Buildings, machinery, and equipment are typically deducted gradually over several years according to IRS depreciation schedules. The IRS explains these rules in detail in IRS depreciation guidance 2026 for business assets. However, a special depreciation allowance changes that timeline.

Instead of spreading deductions over decades, certain tax provisions allow businesses to deduct a much larger portion of the cost immediately. The new rule created under the One Big Beautiful Bill expands this concept for production facilities.

Under the IRS guidance, businesses may be able to claim up to 100% of the unadjusted basis of qualified production property in the taxable year the property is placed in service.

Accelerated deductions improve several aspects of your organization, including: 

• Business cash flow

• Long-term investment planning 

• Annual tax strategy

Why accelerated depreciation matters

Accelerated deductions can significantly affect a company’s financial position. The advantages of accelerated depreciation include:

• Lower taxable income in the investment year

• Improved short-term cash flow

• Greater flexibility for reinvestment

• More predictable tax planning

For example, consider a business that invests several million dollars in a new manufacturing facility. Under traditional depreciation schedules, the company might deduct the cost over many years. With accelerated depreciation, a large portion of that investment could be deducted immediately.

For growing businesses, the impact on cash flow can be substantial.

What Counts as Qualified Production Property?

Not all buildings or property improvements qualify for this new IRS guidance special depreciation rule. The IRS guidance includes specific criteria that determine eligibility.

Definition of Qualified Production Property

So, what is qualified production property? Qualified production property generally refers to nonresidential real property used in production activities. These properties must be used as an integral part of production processes, rather than administrative or office activities.

Common examples may include:

• Manufacturing plants and facilities

• Agricultural processing buildings

• Chemical production facilities

• Petroleum refinement facilities

The key factor determining qualified production property depreciation eligibility is whether the property directly supports the production process. If it does, it likely qualifies for special depreciation. 

What Is a Qualified Production Activity?

The rule focuses on facilities involved in activities that transform raw materials into finished or intermediate products. If a substantial transformation occurs, it likely qualifies for business property owners.

Examples of qualifying production activities include:

Facilities used primarily for office work, retail operations, or general administration services typically do not qualify.

Because classification can be complex, businesses often benefit from professional guidance when evaluating whether a facility meets the requirements. Guidance provided by a cost segregation study for one or multiple properties can help determine whether a property satisfies these rules.

Key Timing Rules Businesses Should Know

Timing is critical when determining eligibility for the special depreciation allowance IRS rule.

When the Property Must Be Placed in Service

The new rule applies to qualified production property placed in service during a specific window. Without an extension, the property will no longer qualify for this rule starting in 2031.

The “placed in service” requirement generally means the property must be ready and available for its intended business use.

For businesses planning new construction or facility upgrades, these dates could influence project timelines. Investments completed during this window may qualify for accelerated deductions.

When Businesses Must Make the Election

The IRS guidance also explains how businesses must elect to treat property as qualified production property.

Key election considerations include:

• The election must be made on a timely filed tax return.

• Taxpayers must properly classify and document qualifying property.

• Additional procedures may be clarified in the upcoming proposed regulations.

Because elections are often difficult to reverse, careful planning is essential.

How the New Rule Could Benefit Small Businesses

Although the rule primarily targets production facilities, many smaller businesses could still benefit.

Companies that manufacture products, process agricultural goods, or operate production plants may see the most direct advantages. However, the broader economic impact may extend to suppliers and contractors involved in facility construction or upgrades.

Potential benefits include:

• Immediate tax deductions for large investments

• Lower taxable income during expansion years

• Greater flexibility for reinvesting capital

• Improved cash flow during growth periods

For example, a manufacturer building a new production line may qualify to deduct a large portion of the facility’s cost upfront. That deduction can reduce the company’s tax liability in the year the facility begins operating.

Maintaining accurate financial records is also critical when claiming deductions tied to property investments. 1-800Accountant's full-service professional bookkeeping solution for small businesses helps ensure financial data supports tax positions and documentation requirements.

Situations Where Businesses Should Be Careful

While the rule offers clear benefits, it also introduces compliance considerations.

Depreciation Recapture Rules

If the same property that qualified for accelerated depreciation later no longer meets the eligibility requirements, the business may need to recognize depreciation recapture.

This means previously claimed deductions for the entire property could be partially treated as taxable income.

IRS recapture rules may apply if:

• The property is converted to a non-qualifying use

• The property is sold or disposed of

• The production activity no longer meets the qualification requirements

Understanding these rules is important before claiming the full deduction.

Complex Qualification Requirements

Another potential challenge is determining whether a property truly qualifies.

Some buildings may serve mixed purposes. For example, a facility might include production space alongside office or administrative areas. In these situations, businesses may need to allocate costs between qualifying and non-qualifying uses carefully.

Because tax treatment can depend on technical definitions and documentation, businesses often benefit from expert business tax planning guidance to determine eligibility and maximize deductions.

How This Fits Into the Broader Tax Changes in the One Big Beautiful Bill

The new production property rule is part of a larger set of tax changes included in the One Big Beautiful Bill.

These provisions aim to encourage investment and strengthen domestic production capacity. The legislation has impacted several areas for business owners, including: 

• Restoring 100% bonus depreciation

• Expanding expensing opportunities

• Introducing new incentives tied to business investments

According to an analysis of new expensing rules under the One Big Beautiful Bill, the legislation reverses the phase-down of bonus depreciation that began in recent years. Businesses can once again fully deduct qualifying investments instead of depreciating them over longer periods.

The law also makes several other changes affecting businesses, including adjustments to reporting thresholds and other tax provisions. Together, these changes represent one of the most significant shifts in business tax incentives.

For businesses that are expanding operations or considering capital investments, understanding these changes could unlock meaningful tax benefits.

Why Tax Planning Matters When New IRS Rules Are Released

Tax law changes rarely operate in isolation. New guidance often introduces technical definitions, election requirements, and documentation rules that can confuse many business owners. Without careful planning, businesses may miss opportunities or inadvertently create compliance risks.

Strategic tax planning can help your business:

• Identify investments that qualify for accelerated deductions

• Structure projects to maximize available tax benefits

• Properly document property classification and use

• Stay compliant with evolving IRS rules

This is why many business owners rely on year-round advisory support from 1-800Accountant. Working with professionals who monitor tax law developments helps to ensure opportunities like the new depreciation rule are applied correctly.

Year-round tax advisory can help your business evaluate upcoming investments and integrate tax planning into long-term financial strategy.
