Cost Segregation in Maryland: Accelerate Depreciation on Your Commercial Property

Cost segregation allows commercial property owners in Maryland to accelerate federal depreciation deductions, generating immediate tax savings and improved cash flow. While Maryland currently decouples from federal bonus depreciation rules, the federal tax savings alone typically deliver returns exceeding 10:1 -- making cost segregation valuable for Baltimore, Columbia, and DC-metro commercial real estate investors.

Why Maryland Is a Strong Market for Cost Segregation

Maryland's commercial real estate market benefits from its strategic location adjacent to Washington, D.C., its diverse economic base, and its concentration of federal contractors, healthcare systems, and technology firms. From the urban core of Baltimore to the affluent suburbs of Montgomery County, from Frederick's bioscience corridor to Annapolis's government and maritime activity, commercial property values support meaningful cost segregation opportunities.

The state's proximity to the nation's capital creates consistent demand for office space, data centers, and specialized facilities serving government contractors. Major healthcare systems -- Johns Hopkins, University of Maryland Medical System -- operate extensive real estate portfolios. The I-270 biotech corridor and emerging markets in Columbia and Frederick generate commercial activity across multiple property types.

How Cost Segregation Works in Maryland

Cost segregation is an IRS-approved tax strategy that applies engineering analysis to commercial property. A qualified team examines your building, reviews construction documents, and identifies components that qualify for shorter depreciation lives under federal guidelines.

Standard depreciation spreads deductions over 39 years for commercial buildings. Cost segregation reclassifies qualifying components into shorter recovery periods:

• 5-year property: Specialized electrical, decorative lighting, carpet, certain fixtures

• 7-year property: Furniture, fixtures, and equipment (FF&E)

• 15-year property: Land improvements, paving, landscaping, site utilities, qualified improvement property

• 39-year property: Nonresidential building structure (remaining basis)

Under the One Big Beautiful Bill Act (OBBBA), property with a recovery period of 20 years or less and placed in service after January 19, 2025 may qualify for 100% first-year bonus depreciation. This applies at the federal level, delivering substantial immediate deductions for reclassified 5-, 7-, and 15-year property.

Maryland and Federal Bonus Depreciation: What You Need to Know

Maryland has historically decoupled from certain federal bonus depreciation provisions. For the 2025 tax year, Maryland decouples from IRC § 168(n) -- the OBBBA bonus depreciation provision.

What this means for Maryland property owners:

• Your cost segregation study still generates substantial federal tax savings through accelerated depreciation and 100% bonus depreciation

• Maryland requires standard MACRS depreciation for state income tax purposes

• The federal savings alone typically justify the study cost many times over

• Your CPA handles the state-federal difference on your return -- the study documentation supports both

• Absent legislative action to permanently decouple, Maryland may conform to OBBBA changes beginning in 2026

The key point: Maryland's decoupling does not eliminate the value of cost segregation. The federal tax savings remain substantial, and most commercial properties in Maryland generate benefits far exceeding study costs.

Maryland Commercial Real Estate Markets

Baltimore -- The Urban Core

Baltimore anchors Maryland's commercial real estate market. The city spans downtown office towers, industrial facilities in the port area, healthcare campuses, and revitalized mixed-use developments.

Cost segregation opportunities in Baltimore include:

• Industrial and port-related facilities: Warehouse and distribution properties carry substantial site work, specialized electrical, and material handling equipment that reclassify at 25-35% of basis.

• Healthcare: Johns Hopkins Hospital and the University of Maryland Medical Center operate extensive real estate with specialized equipment and infrastructure generating high reclassification percentages.

• Hospitality: Inner Harbor hotels and tourism-serving properties carry heavy FF&E loads -- typical reclassification runs 30-40%.

• Office and mixed-use: From the central business district to Harbor East, office buildings contain substantial reclassifiable components.

Columbia -- Planned Community, Active Commercial Market

Columbia represents one of the most successful planned communities in the United States. Its commercial market includes:

• Office parks: The Columbia Gateway corridor hosts corporate campuses and government contractors.

• Retail and mixed-use: The Merriweather District and village centers generate commercial activity.

• Medical office: Howard County General Hospital and affiliated practices operate specialized facilities.

Montgomery County -- Affluent Suburbs and Federal Contractors

Montgomery County's commercial real estate market is concentrated along the I-270 corridor and near the District line:

• Germantown: Industrial parks, data centers, and logistics facilities serving the broader DC metro.

• Silver Spring: Mixed-use development, government offices, and retail near the District border.

• Bethesda: High-value office, life sciences, and medical office properties.

These markets feature higher property values and specialized tenants -- both factors that increase cost segregation benefits.

Frederick -- Bioscience and Manufacturing Growth

Frederick has emerged as a significant bioscience and advanced manufacturing hub:

• Biotech and laboratory facilities: The presence of Fort Detrick and clustered bioscience companies creates demand for specialized R&D properties with high reclassification potential.

• Manufacturing and industrial: Advanced manufacturing facilities carry specialized equipment and infrastructure.

• Healthcare: Frederick Health and affiliated medical offices generate steady commercial activity.

Annapolis -- Government, Maritime, and Tourism

Maryland's capital city combines government activity with tourism and maritime commerce:

• Hospitality: Hotels serving state government visitors, Naval Academy families, and tourists carry substantial FF&E.

• Maritime industrial: Boatyards, marine services, and port facilities generate industrial property opportunities.

• Office: State government contractors and professional services firms occupy office properties throughout the city.

Real Maryland Savings: A Worked Example

Consider a $3.8 million office building in the Baltimore metro area -- a 45,000-square-foot professional office property acquired and placed in service in 2026.

A detailed engineering-based cost segregation study identifies the following reclassifiable components:

• 5-year property (12% of basis): $456,000 -- specialized electrical, decorative lighting, dedicated HVAC units, cabling infrastructure

• 7-year property (6% of basis): $228,000 -- furniture, fixtures, security systems, communications equipment

• 15-year property (10% of basis): $380,000 -- parking lot resurfacing, site utilities, landscaping, sidewalks

• 39-year property (72% of basis): $2,736,000 -- building shell and structural components

Total reclassified basis: $1,064,000 (28% of total basis)

Under current federal law, this reclassified property qualifies for 100% bonus depreciation. At a 37% federal marginal tax rate, the first-year federal tax savings approximate:

$1,064,000 × 37% = $393,680 in federal tax savings

Maryland state tax savings are limited to the standard MACRS depreciation schedule due to decoupling, but the federal savings alone represent a return on investment exceeding 15:1 for a typical study fee.

Frequently Asked Questions

Does Maryland conform to federal bonus depreciation?

For the 2025 tax year, Maryland decouples from IRC § 168(n), the provision establishing 100% bonus depreciation under OBBBA. This means bonus depreciation applies at the federal level but not for Maryland state tax purposes. However, absent legislative action to permanently decouple, Maryland may conform to OBBBA changes beginning in 2026. The federal savings alone typically justify a cost segregation study.

How much does a cost segregation study cost in Maryland?

Fees depend on property size, complexity, and documentation requirements. Most commercial properties between $500,000 and $10 million in basis see study fees ranging from $4,000 to $15,000. Given typical federal tax savings of $100,000 to $800,000 or more, the fee represents a small fraction of the benefit.

Can I get a cost segregation study on property I bought years ago?

Yes. The IRS allows a change in accounting method to catch up missed depreciation without amending prior returns. This "look-back" study generates an immediate deduction for all previously missed accelerated depreciation in the current tax year.

What types of Maryland properties benefit most?

Industrial, hospitality, healthcare, and specialized facilities (laboratories, data centers, government contractor facilities) typically show the highest reclassification percentages. However, any commercial property with a basis exceeding $500,000 should be evaluated. Office buildings and medical properties in Baltimore, Bethesda, and Columbia typically generate substantial savings.

How long does a cost segregation study take?

Most studies are completed within 4 to 6 weeks from engagement. Complex properties or those requiring extensive documentation review may take slightly longer. We coordinate with your CPA to ensure timely delivery before your tax filing deadline.
