Qualified Production Property 100% Deduction 2026: OBBBA's New Factory Depreciation Rule

QPP’s 100% Deduction, the Direct Answer First

Here’s my read on this one: the biggest change in US manufacturing tax policy for 2026 isn’t a credit — it’s a depreciation rule most people are still sleeping on. OBBBA (the One Big Beautiful Bill Act, signed July 2025) created a new category called Qualified Production Property under IRC §168(n), and it lets a company write off the entire cost of a new factory building in the year it opens, instead of spreading that cost over 39 years the way commercial real estate normally works.

For decades, the split was simple and a little unfair to heavy manufacturers: equipment could be expensed fast under bonus depreciation or Section 179, but the building around it — walls, roof, foundation, the structural shell — sat on the slow 39-year straight-line schedule no matter how capital-intensive the project was. QPP breaks that pattern specifically for production real estate. If you’re pouring concrete for a semiconductor fab, a battery plant, or an auto parts facility, the building itself now depreciates like equipment.

I’ll flag the trap early because it’s the one I see companies walk into most: people assume “100% depreciation” is automatic once a factory is built in the US. It isn’t. The construction-start window, the placed-in-service deadline, and how much of the building counts as non-production space all determine whether you get the full deduction, a partial one, or none at all. Get the classification wrong and you either leave real money on the table or face a painful recapture years later.

What Is Qualified Production Property, Exactly?

QPP is the new depreciation category under IRC §168(n). It allows 100% first-year expensing of a nonresidential building used as an integral part of manufacturing, production, or refining activity conducted in the United States.

The key word is “building.” Equipment inside a plant has had a fast-depreciation path for years through §168(k) bonus depreciation and Section 179. The structure itself — the shell, the foundation, the fixed production infrastructure built into the building — never did. QPP reverses that specifically for facilities engaged in:

• Manufacturing — converting raw materials into finished or intermediate goods
• Production — creating tangible property through a physical process
• Refining — processing raw inputs into a sellable finished form

Pure R&D facilities, warehouses without a production function, distribution centers, and office buildings generally fall outside this definition. Projects with mixed use need a tax advisor’s review before ground is broken.

How Does QPP Differ From Section 179 and §168(k) Bonus Depreciation?

These three provisions get lumped together constantly, but they cover different assets with different mechanics. This is the question I get most from manufacturers planning a US build.

	QPP (§168(n))	Section 179	§168(k) Bonus Depreciation
Covers	New nonresidential building structure used for manufacturing/production/refining	Tangible personal property, some real property improvements (roofs, HVAC), software	Tangible personal property, machinery, equipment, most land improvements
Deduction rate	100% in year placed in service	Immediate expensing up to an annual cap	100% (restored by OBBBA for property acquired after 1/19/2025)
Dollar cap	None	Yes — annual limit plus an investment phase-out, both inflation-adjusted	None
Taxable income limit	None — can create or increase an NOL	Yes — capped at active trade or business income for the year	None
New vs. used	Generally new construction, original-use requirement	New or used	New or used
Timing windows	Construction-start and placed-in-service deadlines apply	None beyond placing the asset in service that year	Acquisition and placed-in-service dates apply
Recapture	Yes — multi-year recapture if production use stops	Yes — if business use drops below 50%	Yes — on disposition or change of use

In practice, one factory project usually splits across all three. Production-line machinery goes under §168(k). Smaller improvements and office fit-out often go under Section 179. The building shell itself — the part that used to be stuck on a 39-year schedule — goes under QPP. Treat depreciation as “one bucket” and you’ll almost certainly under-claim.

What Building Qualifies, and What Are the Timing Windows?

QPP runs on a defined window. As currently structured, construction generally needs to begin after January 19, 2025 and before January 1, 2029, with the property placed in service before January 1, 2031. Both the “begin construction” test and the “placed in service” test carry their own technical definitions that the IRS may further clarify — confirm the exact rules on IRS.gov before you commit a project schedule to them.

Here’s a first-pass eligibility checklist worth running against any new facility.

QPP Eligibility Checklist

Item to verify	What to confirm
Location	Property is in the United States (50 states plus certain territories)
Use	Integral to manufacturing, production, or refining
Original use	Taxpayer is the first user of the newly constructed property
Non-qualified space	Office, R&D, sales, lodging, and parking area isn’t an oversized share of the building
Construction start	Ground was broken within the required window
Placed in service	Facility became operational within the required deadline
Long-term intent	No planned sale or use-change within roughly 10 years (recapture exposure)
Documentation	Cost segregation study and construction records are in place

The “non-qualified space” line is where most disputes happen. Office areas, R&D labs, employee cafeterias, and parking generally don’t count as production use, and if that non-production share of the building is too large, it can jeopardize eligibility for that portion — or the whole structure in worse cases. Separating production and non-production space clearly on the architectural plans, before construction starts, is the single highest-leverage move for maximizing this deduction.

Which Industries and Businesses Actually Use QPP?

QPP doesn’t name specific industries in the statute, but it concentrates in capital-intensive manufacturing that’s genuinely building new production real estate on US soil:

• Semiconductor and display fabrication, plus the equipment and materials supply chain around it
• Battery cell and EV component manufacturing
• Automotive assembly and parts production
• Steel and metals processing
• Chemical and petroleum refining
• Large-scale food and beverage processing
• Pharmaceutical and biologics manufacturing

This lines up with the broader US reshoring push — companies bringing chip fabs, battery plants, and parts manufacturing back onshore are the clearest beneficiaries. A midsize domestic manufacturer building a single new plant qualifies just as much as a multinational, as long as the facility itself meets the use and timing tests. One caveat worth repeating: the provision is built around the entity that actually runs production in the building. A pure landlord building a shell to lease out to an unrelated manufacturer runs into limits unless the lease fits a specific related-party exception. Companies weighing how to structure the entity that will own the new facility often need to revisit broader entity-choice questions at the same time — our LLC vs. S-Corp tax strategy guide is a reasonable starting point for that side of the decision.

How Does the 10-Year Recapture Rule Work?

A 100% deduction comes with a long-term commitment attached. If the building stops being used for qualified production purposes within roughly 10 years of being placed in service, a meaningful portion of the deduction already claimed gets added back to income and taxed in the year the change happens.

Situations that commonly trigger recapture:

• Relocating production to another site and selling the original building
• Converting the facility to warehouse, distribution, or office use
• Transferring the property intra-group in a way that changes its qualified use
• Winding down the business and disposing of the property

Because the recapture calculation depends on how much of the intended holding period remains, the real planning question comes before you file anything: is this facility genuinely a long-term production asset, or is there a realistic chance of sale or repurposing within a decade? If there’s real uncertainty, comparing QPP against standard 39-year depreciation — instead of automatically taking the 100% deduction — can be the more conservative call.

How Do You Actually Claim QPP?

QPP is claimed on Form 4562 (Depreciation and Amortization) attached to the business return, but the supporting work is substantial given the size of a typical facility.

1. Document the construction-start and placed-in-service dates — construction contracts, permits, and the certificate of occupancy, organized chronologically.
2. Commission a cost segregation study — this splits total construction cost between production-related structure and fixed equipment versus non-qualified space (offices, parking, etc.), and it’s the backbone of your deduction calculation.
3. Confirm the original-use test — document whether this is new construction or a qualifying conversion of an existing building, since the requirements differ.
4. Calculate the non-production space ratio — based on architectural plans and actual use, to determine what portion of the building qualifies.
5. Complete and attach Form 4562 — with the depreciation method, asset classification, and deduction amount.
6. Document your long-term use intent internally — to manage recapture exposure if questions come up later.

Given the dollar amounts and documentation involved, tax counsel and a cost segregation firm typically get involved from the earliest stages of the project, not after the building opens. Reconstructing this documentation after the fact is possible but harder, and some records simply can’t be recreated retroactively.

What Planning Moves Should You Consider Before Claiming It?

A deduction this large deserves deliberate structuring, not a reflexive “claim the max” approach.

• Align project timing with the statutory window — if a new facility is in the planning stage, check whether the construction-start date can realistically fall inside the required period.
• Model the NOL impact — QPP can generate a net operating loss well beyond current taxable income, so model how that NOL carries forward and offsets future years before assuming it’s pure upside.
• Split equipment and building claims deliberately — pair §168(k) on machinery with QPP on the structure rather than defaulting to one blanket depreciation method.
• Check state-level incentives in parallel — many states run their own manufacturing tax credits or property tax abatements, and some require separate additions back for federal bonus depreciation, so the interaction needs a state-by-state review.
• Weigh recapture risk against standard depreciation — for a facility with real relocation or resale risk inside 10 years, the conservative math sometimes favors regular depreciation.

Projects at this scale usually run alongside broader financing and cash-flow decisions. If your company is also weighing how leftover working capital or seasonal cash gets deployed while a plant is under construction, our ERC claim guide covers another area where manufacturers have left money unclaimed simply from not knowing the mechanics.

The Most Common Mistakes to Avoid

• Treating the building and equipment as one depreciation decision — companies that skip the split between §168(n) building costs and §168(k) equipment routinely under-claim.
• Skipping the cost segregation study — estimating the non-production space ratio without a formal study rarely holds up if the IRS asks for support.
• Misreading the construction-start date — confusing a signed design contract with the actual physical start of construction can throw off the whole timing calculation.
• Claiming 100% without weighing recapture risk — taking the full deduction on a facility with a realistic five-to-seven-year sale horizon, then getting hit with an unplanned recapture later.
• Assuming a lease structure automatically qualifies — a straightforward landlord-tenant build-to-suit deal often doesn’t meet the requirement without a specific exception.
• Ignoring how state incentives interact with federal bonus depreciation — some states require an add-back for federal bonus depreciation that changes the real net benefit of stacking both.

One more thing worth saying plainly: QPP is brand-new as of 2025, and the technical details — exactly how “begin construction” is tested, how much non-production space is tolerable, the precise recapture mechanics — are likely to get further Treasury guidance over the next couple of filing seasons. Treat what’s in this article as the current framework, and confirm the specifics on IRS.gov, ideally with a manufacturing-focused tax advisor, before you commit to claiming this on a project of any real size.
