Most restaurant owners who own their building depreciate the entire property over 39 years and never think about it again. A restaurant cost segregation study challenges that assumption, and for good reason: restaurants contain one of the densest concentrations of reclassifiable assets of any commercial property type.
Commercial cooking equipment, hood systems, POS infrastructure, specialized plumbing, custom millwork, and exterior site improvements all qualify for depreciation schedules far shorter than the building shell they sit inside. Done correctly, a cost segregation study separates those components and front-loads their deductions into the years when the financial benefit is highest.
The sections below cover why restaurants are exceptional candidates for this strategy, how the process works at Seneca, what savings look like at typical restaurant property values, and when the timing makes the most sense.
- ●35 to 45 percent of building cost reclassifies: Restaurants shift far more into shorter schedules than office or retail. Kitchen equipment, hood systems, specialized plumbing, and custom millwork all qualify for 5-year and 15-year treatment instead of the 39-year default.
- ●$150K to $250K Year 1 savings on a $2M property: A typical restaurant building generates this range when cost segregation is combined with 100 percent bonus depreciation for qualifying property placed in service after January 19, 2025. Capital that funds the next renovation cycle rather than waiting on a 39-year schedule.
- ●Every renovation is a new opportunity: Restaurant operators renovate every 5 to 7 years on average. Each remodel generates a fresh pool of reclassifiable assets, and interior improvements to a nonresidential building qualify as Qualified Improvement Property with a 15-year life.
- ●Owners who bought years ago can still recover missed deductions: A retrospective study files all accumulated missed depreciation as a single current-year deduction without amending prior returns.
- ●IRS publishes restaurant-specific guidance: The Cost Segregation Audit Technique Guide includes asset classification rules for food service. An engineering-based study applies that guidance at the component level, the approach the IRS identifies as most defensible under examination.
Why Restaurants Are Prime Candidates for Cost Segregation
Restaurants outperform nearly every other commercial property category for cost segregation because of what they are built to contain.
A standard office or retail buildout is primarily structural: walls, floors, ceilings, and basic mechanical systems. A restaurant buildout is dominated by specialized equipment, purpose-built systems, and finishes that have useful lives far shorter than the building envelope around them.
The IRS recognizes this distinction. Its Cost Segregation Audit Technique Guide provides specific guidance on restaurant asset classification, identifying the components unique to food service that qualify for accelerated depreciation schedules. The IRS’s own framework confirms that commercial kitchen systems, FF&E, and specialized site improvements belong on shorter schedules when properly documented.
That documentation is the work. It is what an engineering-based study provides, and it is what software-only or rule-of-thumb approaches cannot replicate.
Kitchen Equipment and Specialized FF&E
Five-year personal property is the primary driver of first-year savings in a restaurant cost segregation study. In a typical restaurant buildout, FF&E represents 15 to 30 percent of total construction cost, all of it potentially qualifying for accelerated depreciation.
The table below maps common restaurant assets to their MACRS depreciation periods:
The defining characteristic of 5-year personal property is function and removability: assets that serve a specific operational purpose and can be removed or replaced without affecting the building’s structural integrity.
In a restaurant, that covers most of what makes the space operationally functional.
Land Improvements and Site Utilities
Fifteen-year land improvements cover exterior infrastructure tied to the site rather than the building. Restaurants with dedicated parking areas, patio structures, exterior signage, and landscaping carry meaningful pools of 15-year eligible basis.
Qualifying site improvements typically include:
- ●Parking lot paving and striping
- ●Exterior walkways and curbing
- ●Patio structures and outdoor seating infrastructure
- ●Site drainage systems
- ●Exterior monument and pole signage
- ●Landscaping and planters
These elements are frequently recorded as part of the total building cost on the tax return and left on the 39-year schedule by default.
Separating them into the 15-year category is one of the most consistent and overlooked reclassifications in restaurant studies.
Qualified Improvement Property
Qualified Improvement Property (QIP) covers interior improvements to a nonresidential building made after the building was originally placed in service. QIP carries a 15-year depreciation life and qualifies for bonus depreciation under current law.
For restaurant owners, QIP is the primary classification bucket for renovation and remodel costs. Interior work (new flooring, updated kitchen layouts, bar buildouts, lighting upgrades, accessibility improvements, and booth reconfiguration) qualifies as QIP when the work is done after the original building was placed in service.
What does not qualify as QIP: structural enlargements to the building, elevators, escalators, and the internal structural framework. The interior operational improvements that define a restaurant renovation almost always qualify.
The practical consequence is significant. A $400,000 restaurant remodel that qualifies entirely as QIP is eligible for 15-year depreciation and, under current law, potentially full first-year expensing through bonus depreciation. Without a cost segregation study identifying and documenting the QIP components, those same costs default to the 39-year schedule.
The Seneca Restaurant Cost Segregation Study Process
At Seneca, here is what a restaurant cost segregation study looks like from the first conversation through CPA-ready report delivery.
The four stages below move from initial feasibility through tax filing:
Stage 1: Property Review and Feasibility Check
We begin with a review of the property details, purchase or construction cost, tax year, and any renovation history to estimate the potential reclassifiable basis and project whether a study will generate savings that clearly justify the cost.
This feasibility review is provided at no cost and with no commitment. Use the cost segregation calculator as a first-pass estimate, then reach out for a property-specific proposal before deciding to proceed.
For most restaurant properties with a building cost basis above $500,000, the study economics work. Larger properties generate proportionally stronger results.
Stage 2: Engineering Analysis and Asset Classification
A Seneca engineer conducts an on-site or virtual walkthrough of the restaurant property, documenting and photographing individual building components with the specificity required for defensible IRS classification.
Each component is then assigned to its correct asset class (5-year, 7-year, 15-year, or 39-year) using the restaurant industry guidance in the IRS Cost Segregation Audit Technique Guide. This engineering-based approach is what the IRS identifies as the most defensible methodology in the ATG.
Software-only or rule-of-thumb studies that apply percentages to broad categories rather than engineering each component individually cannot replicate the documentation depth this step produces.
Stage 3: Cost Allocation and Report Delivery
The completed study report includes component-level asset schedules, depreciation calculations for each reclassified asset, and full supporting documentation for every classification.
The report is delivered to the restaurant owner and their CPA in a format ready for direct implementation on the tax return.
Stage 4: Filing and CPA Implementation
Our team works alongside the property owner’s CPA to apply the new depreciation schedules on the tax return. For retrospective studies on properties already in service, Form 3115 (Application for Change in Accounting Method) captures all accumulated missed depreciation as a single current-year deduction without requiring amended prior-year returns.

The Financial Returns of a Restaurant Cost Segregation Study
The financial case for a restaurant cost segregation study is built on two dynamics: the reclassification rate and the timing of when deductions hit.
Typical Tax Savings by Property Size
The table below shows estimated first-year federal tax savings for restaurant properties at common cost basis levels. Savings estimates assume 35 percent reclassification, 100 percent bonus depreciation for qualifying property placed in service after January 19, 2025, and a 37 percent federal marginal tax rate.
As a rough rule of thumb, most restaurant properties generate approximately $75,000 to $130,000 in additional first-year federal tax savings per $1,000,000 in building cost.
Whether cost segregation is worth it for your specific property depends on the building composition and your marginal tax rate.
Bonus Depreciation and How It Stacks With Cost Segregation
Cost segregation and bonus depreciation work together because they operate at different layers of the same deduction. Cost segregation identifies which assets qualify for 5-year, 7-year, and 15-year recovery periods. Bonus depreciation then determines what percentage of those reclassified assets can be fully expensed in the year they are placed in service.
The One Big Beautiful Bill, signed July 4, 2025, permanently restored 100 percent bonus depreciation for qualifying property placed in service after January 19, 2025.
For restaurant owners completing construction, purchasing a property, or finishing a renovation today, the combination of cost segregation and full bonus depreciation produces the maximum available first-year federal deduction under current law.
For properties placed in service before January 20, 2025, the prior TCJA phase-out rates apply: 40 percent for 2025 placements before the OBBB effective date and 20 percent for 2026 under the old schedule. Confirming the acquisition or placed-in-service date with your CPA determines which rate applies.
When a Restaurant Cost Segregation Study Makes the Most Sense
Cost segregation delivers maximum benefit at specific moments in a restaurant’s ownership timeline.
The four scenarios below represent the highest-value entry points:
New Construction and Ground-Up Builds
The ideal time for a restaurant cost segregation study is the same tax year the property is placed in service. New construction generates complete, contemporaneous cost records (contractor pay applications, architectural drawings, change orders), which allow the engineer to identify and document qualifying components with the highest accuracy.
Front-loading depreciation at the start of operations improves cash flow in the years when capital is most constrained. For a new restaurant built and placed in service after January 19, 2025, qualifying components can be fully expensed in the first year through bonus depreciation.
Property Acquisitions and Recent Purchases
A cost segregation study should be ordered in the same tax year as a restaurant property purchase. Acquiring a property resets the depreciable basis to the acquisition price, and that stepped-up basis is what the study reclassifies.
Waiting until after year-end delays the bonus depreciation opportunity and reduces the Year 1 financial impact. For most restaurant acquisitions above $500,000 in building cost basis, the study economics are clear.
Renovations and Remodels
Every significant restaurant renovation creates a new cost segregation opportunity. Most restaurant operators renovate on a 5- to 7-year cycle, and each renovation generates a fresh pool of reclassifiable assets, particularly through Qualified Improvement Property.
A $300,000 kitchen renovation or $500,000 full remodel that qualifies as QIP is eligible for 15-year depreciation and, under current bonus depreciation rules, potentially full first-year expensing. That renovation investment generates a tax benefit the same year it is made.
Retrospective Studies on Existing Properties
Restaurant owners who acquired or built their property years ago without commissioning a study have not forfeited the benefit.
A retrospective cost segregation study applies the same engineering methodology to properties already in service. All accumulated missed accelerated depreciation from prior years is captured as a single current-year deduction through a Section 481(a) adjustment on Form 3115.
No amended prior-year returns are required, and the IRS allows lookback studies on properties placed in service as far back as 1987.
For a restaurant owner who purchased a $2 million property five years ago and has been depreciating on the standard 39-year schedule, the accumulated missed deductions can represent $200,000 or more available in the current tax year. This is one of the most overlooked opportunities in the restaurant real estate space.
How to Find the Right Cost Segregation Firm for Your Restaurant
The right cost segregation partner for a restaurant property meets three criteria that directly affect study accuracy and audit defensibility:
Engineering-based methodology: The IRS Audit Technique Guide identifies the detailed engineering approach from actual cost records as the most defensible study methodology. A qualified firm documents each component through physical or virtual inspection and traces every classification to specific cost records. Software-only or statistical sampling approaches produce results that are faster and cheaper to produce, but they lack the component-level documentation required to withstand IRS scrutiny. Ask any provider specifically how they document individual asset classifications and what review process each study undergoes before delivery.
Restaurant industry experience: Restaurants have a distinct component profile (commercial kitchen systems, specialized plumbing, QIP-eligible interior improvements) that requires familiarity with the IRS’s restaurant-specific classification guidance. A firm experienced with food service properties produces more accurate results and catches asset categories that a general-purpose provider may miss entirely.
Audit defense included as standard: Audit protection should come with every study as a written commitment, not as an optional add-on. A firm that stands behind its work unconditionally during an IRS examination demonstrates the quality of its methodology.
Frequently Asked Questions
Here are answers to the questions restaurant owners most commonly have before getting started:
Conclusion
Restaurant owners who default to 39-year straight-line depreciation on their building are leaving a meaningful portion of their tax benefit tied up in the wrong schedule. The density of specialized, short-lived assets in a food service buildout (kitchen systems, dedicated electrical infrastructure, QIP-eligible interior work, and site improvements) means that 35 to 45 percent of total restaurant construction costs typically qualify for faster write-offs under existing IRS rules.
The retrospective study is the opportunity that most owners do not know about. If you have owned your restaurant building for any amount of time without a cost segregation study, the accumulated missed deductions are recoverable in the current filing year without amending a single prior return.
