Introduction

Depreciation is one of the most powerful tax advantages available to real estate investors. Unlike many investments that generate taxable income with limited deductions, multifamily properties allow owners to recover the cost of their assets through annual depreciation deductions.

However, not all depreciation strategies are the same. Understanding bonus depreciation vs standard depreciation can dramatically impact after-tax returns, cash flow, and overall investment performance.

In 2026, this conversation has become even more important due to major legislative changes. The restoration of permanent 100% bonus depreciation under the OBBBA has created new planning opportunities for multifamily investors looking to maximize first-year deductions while balancing long-term tax consequences.

This guide explains how standard depreciation works, how bonus depreciation accelerates deductions, where cost segregation fits into the equation, and what investors should consider before making a decision.

Standard Depreciation: 27.5-Year Residential vs 39-Year Commercial

The IRS generally requires real estate assets to be depreciated over a prescribed recovery period under the Modified Accelerated Cost Recovery System (MACRS).

According to IRS Publication 946, residential rental property uses a 27.5-year depreciation schedule, while nonresidential commercial property uses a 39-year schedule. This system spreads deductions across the useful life of the asset rather than allowing an immediate write-off. IRS Publication 946 recovery period table.

Standard Depreciation Overview

Property Type	Recovery Period
Residential Rental Property	27.5 Years
Nonresidential Commercial Property	39 Years
Land	Not Depreciable
Qualified Land Improvements	Often 15 Years

For multifamily investors, most building value falls into the 27.5-year category. Land itself cannot be depreciated.

Benefits of Standard Depreciation

• Predictable annual deductions
• Lower risk of future recapture issues
• Simpler tax reporting
• Suitable for long-term holders

Standard depreciation creates consistency, which many investors value when planning long-term cash flow and taxable income.

Bonus Depreciation: Front-Loading the First-Year Write-Off

Bonus depreciation allows taxpayers to deduct a significant portion, or potentially all, of certain qualifying assets in the year they are placed in service rather than depreciating them over multiple years.

Under IRC §168(k), bonus depreciation generally applies to property with a recovery period of 20 years or less.

The biggest misconception among investors is that apartment buildings themselves qualify for bonus depreciation. They generally do not. Instead, investors use cost segregation studies to identify components within the property that qualify for shorter recovery periods.

How Bonus Depreciation Works

Without bonus depreciation:

• Asset depreciated over 5, 7, or 15 years

With bonus depreciation:

• Eligible asset can be largely or fully deducted immediately

The tax savings occur upfront, increasing early-year cash flow.

Why Investors Like Bonus Depreciation

• Larger first-year deductions
• Improved after-tax cash flow
• Ability to offset taxable rental income
• Greater flexibility for high-income investors

The strategy does not create new deductions; it accelerates existing deductions into earlier years.

The Class-Life System (5-, 7-, 15-, 27.5-, 39-Year)

The IRS uses a recovery system known as class life depreciation to determine how quickly different assets can be depreciated.

Common Recovery Periods

Asset Category	Typical Recovery Period
Appliances	5 Years
Carpeting	5 Years
Furniture	7 Years
Landscaping	15 Years
Parking Lots	15 Years
Multifamily Building Structure	27.5 Years
Commercial Building Structure	39 Years

IRS MACRS recovery period guidance outlines these classifications.

Understanding these categories is critical because bonus depreciation generally applies to assets with recovery periods of 20 years or less.

Cost Segregation: How It Unlocks Bonus Depreciation

Cost segregation is the bridge between multifamily real estate and bonus depreciation. A cost segregation study identifies building components that can be reclassified from the 27.5-year category into shorter recovery periods. This is why cost segregation bonus depreciation has become one of the most discussed tax strategies among apartment investors.

Common Reclassified Assets

• Flooring
• Cabinetry
• Appliances
• Decorative lighting
• Landscaping
• Sidewalks
• Parking areas
• Fencing

Many engineering-based cost segregation studies identify approximately 20% to 35% of a property’s depreciable basis as qualifying for shorter recovery periods. STR Tax’s discussion of cost segregation allocations and bonus depreciation.

Example

Assume:

• Purchase Price: $5,000,000
• Land Value: $1,000,000
• Depreciable Basis: $4,000,000

Without cost segregation:

• Entire building depreciated over 27.5 years

With cost segregation:

• Approximately $1,000,000 may qualify for accelerated schedules
• Potentially eligible for bonus depreciation

This is where the largest tax savings opportunities typically emerge.

The OBBBA Update (Permanent 100% Bonus, Post-1/19/2025)

One of the biggest developments affecting multifamily depreciation 2026 is the enactment of the One Big Beautiful Bill Act (OBBBA).

Under prior law, bonus depreciation was scheduled to phase down:

Year	Bonus Depreciation Rate
2025	40%
2026	20%
2027	0%

However, the OBBBA changed the landscape. According to Wipfli’s OBBB tax change summary, property acquired and placed in service after January 19, 2025 now qualifies for permanent 100% bonus depreciation.

Acquisition timing determines eligibility under the new rules.

Why This Matters

Investors can once again:

• Conduct cost segregation studies
• Accelerate qualifying components
• Potentially deduct 100% of eligible assets in year one

The restoration of permanent bonus depreciation significantly increases the value of cost segregation strategies for multifamily investors.

Section 179 vs Bonus Depreciation

Many investors confuse section 179 vs bonus depreciation, but they operate differently.

Key Differences

Feature	Section 179	Bonus Depreciation
Income Limitation	Yes	No
Creates Losses	Limited	Yes
Property Types	More Restricted	Broader Eligibility
Automatic Application	No	Generally Yes
Phase-Out Threshold	Yes	No

The OBBBA also increased Section 179 limits. According to CPA Validated’s OBBBA breakdown, the Section 179 cap increased to $2.5 million with a $4 million phaseout threshold.

Which Is Better?

For many multifamily investors:

• Bonus depreciation offers greater flexibility.
• Section 179 may be useful for smaller businesses with equipment purchases.
• Real estate investors often rely more heavily on bonus depreciation due to broader applicability.

When to Choose Each

There is no universal answer.

Bonus Depreciation May Be Better When

• Income is unusually high
• Investors want maximum deductions immediately
• Cost segregation identifies substantial short-life assets
• Cash flow preservation is important

Standard Depreciation May Be Better When

• Investors expect higher future tax rates
• Long-term income smoothing is preferred
• The holding period is short
• Recapture concerns outweigh current tax savings

Some investors intentionally elect out of bonus depreciation because they prefer future deductions rather than immediate ones.

Tax strategy should align with investment strategy, not simply maximize deductions in the current year.

Worked Example: $5M Multifamily Asset Through Both Methods

Assume:

• Purchase Price: $5,000,000
• Land: $1,000,000
• Building Basis: $4,000,000

Scenario A: Standard Depreciation

Annual deduction:

$4,000,000 ÷ 27.5

= Approximately $145,455 annually

Scenario B: Cost Segregation + Bonus Depreciation

Assume:

• 25% of building basis reclassified
• Reclassified amount = $1,000,000
• Remaining building basis = $3,000,000

First-year deductions:

Component	Deduction
Bonus Depreciation Assets	$1,000,000
Remaining Building Depreciation	~$109,091
Total Year-One Deduction	~$1,109,091

Result

Method	First-Year Deduction
Standard Depreciation	~$145,455
Cost Seg + Bonus	~$1,109,091

This example demonstrates why cost segregation studies remain highly valuable for multifamily acquisitions.

Recapture at Sale: The Hidden Cost

One of the most overlooked topics in accelerated depreciation planning is recapture at sale.

When investors claim depreciation deductions, the IRS generally requires a portion of those deductions to be recaptured when the property is sold.

Why It Matters

The larger the accelerated depreciation deduction today:

• The smaller the future tax basis
• The larger potential recapture later

Investors often focus on the upfront benefit while ignoring the eventual tax liability.

Industry discussions among investors and tax professionals consistently highlight recapture as a major consideration when evaluating cost segregation strategies, particularly for shorter holding periods. Example discussion regarding recapture considerations and holding periods.

Strategies to Manage Recapture

• Longer holding periods
• Strategic refinancing
• 1031 exchanges
• Careful exit planning

Bonus depreciation can create substantial tax savings today, but investors should understand the future tradeoff.

Investor Action Items

If you’re evaluating multifamily acquisitions in 2026, consider the following checklist:

Before Closing

• Review depreciation assumptions
• Estimate land allocation
• Evaluate projected taxable income
• Determine if cost segregation is warranted

After Acquisition

• Order a cost segregation study
• Review bonus depreciation eligibility
• Confirm OBBBA qualification dates
• Coordinate with a CPA specializing in real estate

Before Sale

• Model depreciation recapture
• Explore 1031 exchange opportunities
• Analyze after-tax proceeds

A proactive approach can significantly improve overall after-tax returns.
