Qualified Production Property: Definition and How It Works

Qualified production property (QPP) is a category of nonresidential real property — specifically domestic manufacturing, processing, refining, extraction, mining, agricultural, and construction facilities — that is eligible for 100% first-year expensing under IRC §168(n), a provision enacted by the One Big Beautiful Bill Act (OBBBA, July 4, 2025). The significance of the provision is that buildings and structural components are normally ineligible for bonus depreciation under IRC §168(k) — those assets are assigned a 39-year MACRS recovery period — but §168(n) creates a parallel immediate-expensing rule for qualifying production facilities, allowing a taxpayer constructing a new domestic factory to deduct 100% of the building's cost in the year it is placed in service rather than at roughly $25,600 per million dollars per year under standard MACRS.

Four Criteria for QPP Status

IRC §168(n) defines qualified production property as nonresidential real property (and its structural components) that meets all four of the following requirements:

  1. Used in a qualified production activity. The property must be actively used in manufacturing, production, refining, extraction, mining, agriculture (including horticulture and aquaculture), or construction. Administrative buildings, sales offices, and warehouses that merely store finished goods generally do not qualify — the production activity must occur in the space itself. IRS Notice 2025-44 provides preliminary activity-boundary guidance and signals forthcoming proposed regulations.

  2. Located in the United States. The property must be within the United States as defined by IRC §638 — the 50 states, the District of Columbia, and U.S. territorial waters. Puerto Rico and U.S. territories are excluded from §168(n) unless separately designated by statute.

  3. Original use begins with the taxpayer. The taxpayer must be the first to place the property in service. Acquiring an existing manufacturing facility does not qualify. Substantial rehabilitation that amounts to new construction may qualify on a facts-and-circumstances basis, but the IRS has not issued definitive guidance (IRS Notice 2025-44 §4.04).

  4. Construction begins after January 19, 2025, and the property is placed in service after that date. For buildings under construction at OBBBA's enactment, the "construction begins" safe harbor from §168(k) applies: at least 10% of total project cost must be incurred on or after January 20, 2025. Pre-enactment costs are not eligible.

How the §168(n) Deduction Works

The §168(n) deduction is 100% of the adjusted basis of the qualifying building and structural components in the year placed in service. Key mechanical features:

  • No income limitation. Unlike Section 179, §168(n) can create or increase a net operating loss (NOL) with no floor. A taxpayer building a $15 million qualifying facility can claim the full $15 million deduction even if it results in a $12 million business loss.
  • Applied before other depreciation. The §168(n) deduction is computed before the Section 179 election and before §168(k) bonus depreciation on the same return.
  • No phase-down schedule. The OBBBA made the 100% rate permanent; unlike the TCJA's scheduled phase-out for bonus depreciation, QPP expensing does not decrease over time under current law.
  • Elect-out available. Taxpayers may elect out of §168(n) for any property class placed in service during the year. The election is made on the timely filed return for that year and is irrevocable without IRS consent.
  • Reported on Form 4562. QPP is identified separately from §168(k) bonus property on the depreciation schedule; practitioners should monitor IRS form instructions for 2025 and 2026 returns, as the IRS is expected to update Form 4562 to reflect §168(n).

Key Planning Considerations

Recapture at Sale

The most significant planning risk for QPP is depreciation recapture. When a taxpayer claims 100% §168(n) expensing, the adjusted basis of the building falls to zero. A subsequent sale triggers recapture of the entire gain (up to the amount expensed) as ordinary income under IRC §1245 — not the preferential 25% unrecaptured §1250 rate that typically applies to real property. A client who expenses a $10 million QPP facility and sells it five years later for $9 million recognizes $9 million of ordinary income, which at a combined federal-state ordinary rate of 40%+ is materially worse than the §1250 outcome that would have applied under standard depreciation. Clients who anticipate a near-term sale should model the recapture cost against the time-value benefit before claiming the deduction.

Excess Business Loss Limitation

For pass-through entities (S corporations, partnerships, and sole proprietors), a large §168(n) deduction flowing to individual owners may exceed the excess business loss (EBL) threshold — $325,000 for single filers and $650,000 for married filing jointly in 2026 under IRC §461(l). Disallowed loss becomes a net operating loss carryforward subject to the 80% income limitation. C corporations are not subject to §461(l) and can absorb the full deduction without this restriction, which may favor C corporation structure for large-scale domestic capital investment programs.

State Tax Non-Conformity

States with static IRC conformity (such as New York) will not recognize §168(n) without separate state legislation. States with rolling conformity may adopt the provision by default. California, which decoupled from federal bonus depreciation, is expected to treat QPP under its pre-OBBBA depreciation rules. The practical result is an addition modification in year one on the state return — increasing state taxable income — with subtraction modifications in later years as state depreciation continues. Model the state tax cost before finalizing the §168(n) election, particularly for multi-state manufacturers.

Interaction With Cost Segregation

Cost segregation loses part of its traditional function for new QPP construction: because the building itself is immediately expensed under §168(n), reclassifying building components into shorter MACRS lives provides no additional federal acceleration for the structural portion. However, cost segregation retains value for (1) qualified improvement property (QIP) in existing buildings, (2) partial §168(n) opt-out scenarios, and (3) state returns in non-conforming jurisdictions where the reclassified components receive accelerated state depreciation. See Cost Segregation Studies: When They're Worth It and How to Execute Them for the QIP analysis that remains relevant regardless of §168(n) elections.

Related Terms

  • Bonus Depreciation — the §168(k) companion provision that covers personal property and QIP but excludes buildings; QPP fills the gap for manufacturing structures
  • MACRS — the standard depreciation system that applies to QPP if the §168(n) election is not made or is elected out of; 39-year nonresidential real property
  • Depreciation Recapture — §1245 recapture on expensed QPP sold above adjusted basis; ordinary income rate applies rather than the lower §1250 capital gain rate
  • Excess Business Loss — the §461(l) limit that can cap a QPP deduction for pass-through entity owners in the year of claim
  • Net Operating Loss (NOL) — §168(n) can generate an NOL in the year the building is placed in service; excess business loss converts to an NOL carryforward subject to the 80% limitation

How CPAs Use QPP in Practice

QPP analysis arises whenever a manufacturing, agricultural, or industrial client is undertaking new domestic construction. The CPA's role is to determine: (1) whether the intended use of the facility qualifies under the §168(n) activity test (IRS Notice 2025-44 is the current guidance), (2) whether the client's tax profile favors immediate expensing or a conventional depreciation approach given recapture risk, EBL limitations, and state non-conformity costs, (3) how the deduction interacts with the QBI calculation — UBIA for §199A purposes is not reduced by §168(n) expensing, preserving the UBIA deduction component even after full first-year write-off, and (4) whether cost segregation still adds value for QIP or state tax purposes. For the full planning analysis, including the §168(n) vs. §168(k) vs. §179 comparison table and opt-out modeling framework, see Qualified Production Property Expensing Under OBBBA: The CPA's Guide to IRC §168(n).
