IRS Notice 2026-16: QPP Implementation Guidance
IRS Notice 2026-16 provides implementation guidance for Section 168(n) Qualified Production Property under OBBBA. The Notice defines construction-begin for QPP purposes, specifies qualified production use categories, addresses partial-property treatment, and clarifies the placed-in-service rules for production facilities.
Construction-begin definition
Construction begins for QPP purposes on the date physical work of a significant nature starts. The Notice references the standard used for energy tax credits as a parallel definition. Site preparation, foundation work, and major structural work all count as construction-begin events.
Pre-construction activities (design, permitting, land acquisition) do not begin construction. The property must reach the physical-work stage to clock the construction-begin date.
Qualified production use
Manufacturing facilities, agricultural production property, and other production-related nonresidential real property qualify. The Notice provides specific category definitions and exclusions.
Pure office space, retail, or warehousing for non-production purposes does not qualify. The property must be used in qualified production after placed in service.
Placed-in-service rules
The property must be placed in service before January 1, 2031. Standard placed-in-service rules apply: the property must be ready and available for its assigned production function.
Multi-phase construction projects can have multiple placed-in-service dates. Each phase is analyzed independently under the QPP requirements.
