Why Qualified Improvement Property Matters
When property owners invest in renovations, the tax treatment of those improvements can vary significantly depending on how they are classified. Qualified Improvement Property (QIP) is a tax category that allows certain interior building improvements to be recovered at a much faster rate than typical building components — turning what would otherwise be decades-long deductions into front-loaded tax savings.
For investors and operators focused on cash flow, this distinction matters. Accelerating depreciation means larger deductions in the early years of ownership, which can offset income and improve the overall return on a renovation investment. This is especially worth understanding for those making post-acquisition improvements or operating short-term rentals that may qualify under nonresidential property rules.
What Is Qualified Improvement Property?
At its core, QIP is a federal tax classification for a specific type of building improvement. Congress established the category to encourage investment in commercial real estate by making interior renovations more economically attractive from a tax standpoint.
To fall under QIP, an improvement must check several boxes. It must be made to the interior of a building that is already in use — meaning the work happens after the property has been placed in service, not as part of initial construction or setup. The property itself must be nonresidential real estate, and the work cannot involve structural changes, building expansions, or the addition of elevators or escalators.
In short, QIP targets practical, functional interior renovations — the kind of work that upgrades or refreshes a space without altering the building’s fundamental structure.
How QIP Accelerates Depreciation Compared to Standard Building Property
The standard depreciation period for commercial real property is 39 years. Under QIP rules, qualifying interior improvements are instead recovered over 15 years — more than cutting the timeline in half. That shift alone can produce substantially larger annual deductions for property owners who renovate after acquisition.
On top of the shortened recovery period, QIP also opens the door to bonus depreciation. This provision allows a property owner to deduct a significant portion — or even the full amount — of the improvement cost in the very year it is placed in service, rather than spreading it across 15 years.
Under prior law, bonus depreciation had been scheduled to phase down annually. However, legislation enacted in January 2025 restored 100% bonus depreciation for qualifying property placed in service after January 18, 2025. The applicable bonus rates are therefore:
- 2023: 80%
- 2024: 60%
- January 1–January 18, 2025: 40%
- After January 18, 2025: 100%
This restoration significantly changes renovation timing strategy. Improvements completed after January 18, 2025 may again qualify for a full immediate deduction, allowing property owners to recover costs faster and improve short-term cash flow. As a result, renovation planning decisions are no longer constrained by the previously scheduled phase-out timeline — and many owners are reassessing project timing to take advantage of the reinstated benefit.
When Short-Term Rentals May Be Treated as Nonresidential Property
Because QIP is limited to nonresidential real property, short-term rental operators face an additional threshold question: does the property itself qualify? The answer is not automatic. Residential rental properties are generally excluded from QIP, so the classification of the property determines whether any of its interior improvements can benefit from this treatment.
Short-term rentals occupy a gray area. When a short-term rental operates more like a lodging or hospitality property than a traditional residential rental, it may qualify as nonresidential real property for depreciation purposes depending on the specific facts and usage of the property. The following operational characteristics tend to support that classification:
- Average guest stays of fewer than 30 days
- High occupancy turnover between different guests
- Fully furnished units provided for short stays
- Housekeeping or cleaning services between each stay
- Active, hospitality-style management practices
It is worth emphasizing that no short-term rental is automatically classified as nonresidential. Each property must be assessed individually based on how it is actually operated, and the factual record supporting that classification should be well-documented.
Timing Rules for STR Renovations
Even when a short-term rental qualifies as nonresidential real property, the timing of improvements still plays a critical role. Interior improvements only qualify as QIP if they are completed after the property has already been placed in service. Work completed before the property is first placed in service as income-producing nonresidential property generally does not qualify as QIP.
This means that for STR operators, the sequence of events matters just as much as the nature of the work itself. A renovation completed one month after the property begins accepting guests may qualify, while identical work done in the weeks before the first guest checks in may not. Keeping clear records of when the property was first placed in service and when each improvement was completed is essential for supporting a QIP classification.
Examples of STR Upgrades That May Become QIP
When a short-term rental meets both the nonresidential classification requirement and the placed-in-service timing rule, many common renovation projects can qualify for QIP treatment. Examples of improvements that may qualify include:
- Flooring replacements throughout guest spaces
- Interior lighting upgrades and fixture replacements
- Cabinet installation in kitchens and bathrooms
- Electrical modifications inside walls
- Interior partitions and layout improvements
These are the types of upgrades STR operators frequently make between ownership cycles or as part of property refreshes — and when properly documented and timed, they can generate meaningful accelerated deductions rather than being slowly recovered over decades.
Interior Improvements That Typically Qualify as QIP
Beyond STR-specific examples, a broad range of interior renovation work qualifies as QIP across nonresidential properties generally. The common thread is that qualifying improvements are interior, functional, and do not alter the structural character of the building. Common examples include:
- Drywall installation and interior framing
- Ceiling work and finishes
- Flooring replacement of any type
- Interior lighting system upgrades
- Plumbing modifications within the building interior
- Electrical upgrades and rewiring inside walls
- Interior doors and hardware
- Built-in cabinetry and millwork
- Non-structural partition walls and layout changes
These improvements share a key characteristic — they enhance or modernize a space without touching the core structure that holds the building together.
Improvements That Do Not Qualify as QIP
Understanding the exclusions is just as important as knowing what qualifies, because misclassifying ineligible work as QIP is a frequent and costly mistake. The following improvements do not qualify:
- Roof replacements and exterior structural repairs
- Modifications to load-bearing walls or the building’s structural framework
- Building expansions or additions
- Installation of elevators or escalators
Any work that touches the building’s structural skeleton — the components that define its size, shape, and load-bearing capacity — is outside the scope of QIP regardless of how significant or expensive the project is.
Exterior Improvements That Are Not QIP but May Still Qualify for Accelerated Depreciation
Exterior site improvements also fall outside QIP, but that does not mean they are without tax benefits. Many exterior land improvements qualify for a 15-year recovery period under a separate depreciation classification, including:
- Parking lots and paved surfaces
- Sidewalks and walkways
- Fencing
- Landscaping
The important distinction is that these items should not be filed as QIP — they belong in their own category. Structural exterior components like roofs typically remain on the standard 39-year schedule. Getting this right matters both for accuracy and for audit protection.
Timing Rules That Determine Whether Improvements Qualify
One rule that catches many property owners off guard is the placed-in-service requirement. For an improvement to qualify as QIP, the building must already be in service before the renovation work is completed. Improvements done as part of getting a building ready for its very first use — even if they are otherwise identical to qualifying work — do not meet this standard.
This rule has real implications for how renovation projects are planned and documented. In some cases, phasing improvements strategically — completing some work after the property is already operational — can make a meaningful difference in what qualifies for accelerated treatment. Keeping detailed records of when work was contracted, when it started, and when it was completed is essential for supporting a QIP classification during any IRS review.
Common Mistakes Property Owners Make When Identifying QIP
A few errors come up repeatedly when property owners attempt to identify QIP on their own:
- Misclassifying residential rental property as nonresidential. Standard long-term residential rentals are generally ineligible for QIP. Without clear facts supporting a nonresidential classification, improvements to those properties remain on the 27.5-year residential depreciation schedule.
- Including structural or exterior improvements incorrectly. Roof work, structural repairs, and land improvements each belong in separate depreciation categories — not QIP. Grouping them together inflates QIP claims and creates audit exposure.
- Overlooking the placed-in-service timing rule. Improvements made before or during a building’s initial setup period do not qualify, regardless of what the work involves or how much it cost.
Key Takeaways: How QIP Supports Faster Cost Recovery
Qualified Improvement Property offers a clear and practical path to recovering interior renovation costs faster for owners of qualifying nonresidential real estate. Rather than waiting 39 years to fully deduct the cost of improvements, eligible work is recovered over 15 years — and potentially much sooner through bonus depreciation.
For short-term rental operators, QIP adds another layer of planning value. Properties that qualify as nonresidential and undergo interior improvements after being placed in service may benefit from the same accelerated treatment available to traditional commercial properties.
The key is making sure the right pieces are in place: the property classification is supportable, the improvements are interior and non-structural, and the timing follows the placed-in-service rule. When all of those conditions are met, QIP becomes one of the more straightforward and impactful tools available for reducing taxable income in the years renovations are completed.
