When you invest in improving your building’s interior — whether to modernize your space, attract tenants, or enhance operations — the IRS offers an often-overlooked reward: Qualified Improvement Property (QIP). This designation allows business owners to depreciate interior improvements faster, unlocking powerful cash flow benefits.
At AE Tax Advisors, we help business owners classify and deduct improvements under IRS Publications 946, 535, and 527, ensuring compliance with the current Qualified Improvement Property (QIP) rules established by Congress in the CARES Act and Tax Cuts and Jobs Act (TCJA).
This article builds upon The Business Owner’s Guide to Cost Segregation Studies and Building Component Analysis, The Complete Guide to Real Estate Depreciation for Business Owners, and The Complete Guide to Section 179 and Bonus Depreciation.
What Is Qualified Improvement Property (QIP)?
Qualified Improvement Property (QIP) refers to any improvement made to the interior of nonresidential real property after the building was first placed in service.
In simpler terms: if you own an office, retail space, or warehouse and make interior renovations — those costs likely qualify as QIP.
Under Section 168(e)(6) of the Internal Revenue Code, QIP has a 15-year recovery period and is eligible for 100% bonus depreciation through 2022, phasing down to 60% in 2025.
AE Tax Advisors identifies which interior projects qualify for accelerated deduction treatment under these updated provisions.
Step 1: What Qualifies as QIP
According to IRS Publication 946 and IRC §168(k), QIP includes:
- Interior renovations to nonresidential buildings.
- Lighting, drywall, ceilings, and flooring upgrades.
- HVAC, plumbing, and electrical improvements.
- Fire protection and alarm systems.
To qualify, the improvement must:
- Be made to the interior of the building.
- Occur after the building was first placed in service.
- Not enlarge the building or add new structural framework.
AE Tax Advisors categorizes each renovation detail to ensure it meets these standards for tax purposes.
Step 2: What Does Not Qualify
Certain property improvements do not qualify as QIP:
- Building expansions or new additions.
- Elevators or escalators.
- Structural framework work (load-bearing walls, roofs, etc.).
- Residential rental property improvements.
QIP applies only to nonresidential real estate — commercial buildings, warehouses, offices, or retail spaces.
AE Tax Advisors reviews architectural and contractor invoices to separate QIP from non-qualifying structural work.
Step 3: The QIP Correction Under the CARES Act
When Congress passed the Tax Cuts and Jobs Act (TCJA) in 2017, they accidentally assigned QIP a 39-year recovery period — excluding it from bonus depreciation. The CARES Act of 2020 corrected this error retroactively, setting the recovery period at 15 years and reinstating bonus depreciation eligibility.
That correction opened the door for property owners to amend prior returns or file Form 3115 for catch-up deductions under IRC §481(a).
AE Tax Advisors helps clients review renovations completed between 2018 and 2020 to capture missed deductions — often resulting in substantial refunds.
Step 4: Bonus Depreciation on QIP
For 2025, bonus depreciation on QIP is 60% under Section 168(k). This means business owners can deduct 60% of the cost of qualifying improvements immediately in the year they’re placed in service.
Example:
- $300,000 of interior improvements qualify as QIP.
- 60% bonus depreciation = $180,000 immediate deduction.
- Remaining $120,000 depreciated over 15 years.
AE Tax Advisors applies bonus depreciation automatically where advantageous, optimizing timing across current and future tax years.
This ties directly to The Complete Guide to Section 179 and Bonus Depreciation.
Step 5: QIP vs. Section 179 Expensing
Both QIP and Section 179 allow immediate write-offs, but their rules differ.
Section 179 allows up to $1,220,000 in deductions (2025 limit), but it phases out at $3,050,000 in total purchases and cannot create a loss.
Bonus depreciation on QIP has no spending cap and can generate losses.
AE Tax Advisors compares both methods to select the combination that yields the greatest net tax savings.
Step 6: Common QIP Examples
Examples of QIP include:
- Upgrading tenant suites.
- Converting office layouts.
- Installing new lighting and drop ceilings.
- Replacing carpets, tile, or wall coverings.
- Adding fire sprinklers or soundproofing.
Even cosmetic or comfort-related improvements may qualify when performed within the building envelope.
AE Tax Advisors documents each improvement category with itemized contractor breakdowns for compliance.
Step 7: Integration With Cost Segregation
Cost segregation and QIP often work together. Cost segregation identifies short-life assets (5-, 7-, or 15-year property), while QIP focuses specifically on interior improvements.
When combined, they can accelerate both the original structure’s components and subsequent renovations.
AE Tax Advisors coordinates these analyses for a unified depreciation strategy under Publication 946.
This connects directly to The Business Owner’s Guide to Cost Segregation Studies and Building Component Analysis.
Step 8: Partial Dispositions and Write-Offs
If you remove or replace existing components during renovation, you can write off the remaining basis of those removed items under partial disposition rules in Publication 946.
Example:
If you replace a $50,000 HVAC system with a new $80,000 unit, the remaining undepreciated value of the old system becomes an immediate deduction.
AE Tax Advisors tracks these components within your fixed asset schedule to ensure proper write-offs.
This ties to The Ultimate Guide to Business Asset Disposal and Replacement.
Step 9: Leasehold vs. Owner Improvements
QIP benefits both landlords and tenants:
- Landlords can claim QIP on capitalized tenant improvements.
- Tenants may claim QIP if they pay for and own the improvements.
Ownership is determined by who bears the cost and controls the asset — not necessarily who occupies the space.
AE Tax Advisors reviews lease language to allocate deductions properly and avoid duplication.
Step 10: QIP in Buildouts and Tenant Allowances
When negotiating tenant improvements (TIs) or buildouts, proper structuring determines who can take the deduction.
Example:
If a landlord provides a $200,000 tenant improvement allowance, and the tenant directs the construction, the landlord typically owns the improvement — and takes the deduction.
AE Tax Advisors advises both parties on structuring TI agreements for maximum tax benefit and clear compliance.
Step 11: How to Claim QIP
You claim QIP depreciation on Form 4562. If claiming bonus depreciation, it must be reflected in Part II of the form, and the asset should be listed as 15-year property.
For missed deductions, Form 3115 (Change in Accounting Method) allows retroactive adjustments under the §481(a) catch-up provision.
AE Tax Advisors prepares these filings with detailed QIP documentation, ensuring every deduction is captured and defensible.
Step 12: Recordkeeping for QIP
To substantiate QIP deductions, retain:
- Invoices and contracts describing the improvements.
- Photos and plans showing interior-only work.
- Dates when the improvements were placed in service.
- Cost segregation reports if applicable.
AE Tax Advisors maintains digital QIP audit files under Publication 583 guidelines, ensuring IRS compliance and long-term traceability.
