How does REPS cost segregation work together?

When a taxpayer qualifies as a real estate professional and materially participates in rental activities, cost segregation depreciation becomes non-passive. This allows it to offset ordinary income including wages, self-employment income, and business profits, rather than being suspended under the passive loss rules.

What are the reps depreciation benefits in dollar terms?

The dollar value depends on the property basis, the amount reclassified to shorter life assets, whether bonus depreciation applies, and the taxpayer's marginal rate. A qualifying investor in the 37% bracket who generates $500,000 of non-passive depreciation from cost segregation would reduce tax liability by approximately $185,000 in that year.

Can real estate professional cost segregation deductions offset W-2 income?

Yes. Non-passive rental losses generated by a real estate professional who materially participates can offset W-2 wages on Form 1040. This is the primary financial motivation for investors with high employment income to pursue REPS qualification.

Does REPS status apply to all properties in a portfolio automatically?

REPS status qualifies the taxpayer, not individual properties. Each property still requires material participation to produce non-passive losses. A grouping election aggregates the properties, which makes it easier to satisfy material participation across the portfolio as a whole.

What happens to suspended passive losses when REPS status is achieved?

Prior suspended passive losses from years before REPS status was achieved remain passive and cannot be released simply by qualifying in a later year. They continue to be suspended until the taxpayer has sufficient passive income or disposes of the passive activity. The REPS treatment applies prospectively to the years it is satisfied.

How does bonus depreciation interact with REPS cost segregation tax savings?

Bonus depreciation accelerates cost segregation deductions into a single year rather than spreading them over 5, 7, or 15 years. Combined with REPS status, this creates a large non-passive deduction in year one, which can substantially reduce or eliminate federal income tax liability in that year.

Are the reps tax savings permanent or timing differences?

The tax savings are primarily timing benefits. Cost segregation accelerates deductions that would otherwise be taken over a longer period. The total depreciation deducted over the life of the property is the same; the benefit is having those deductions available earlier when the time value of money makes them more valuable.

Does cost segregation with REPS create depreciation recapture risk?

Yes. Accelerated depreciation claimed today creates potential depreciation recapture exposure on disposition. Section 1245 recapture applies to personal property components and is taxed as ordinary income. Section 1250 recapture applies to real property and is taxed at a maximum 25% rate. These recapture rules apply regardless of REPS status.

How REPS Changes Cost Segregation Benefits

REPS cost segregation is the combination that transforms accelerated depreciation from a deferred tax asset into an immediate, usable deduction. Without real estate professional status, cost segregation studies create passive losses that are suspended for investors without passive income to absorb them. With REPS status and material participation, the same depreciation becomes non-passive and can offset wages, business income, and other forms of ordinary income in the current year.

Understanding real estate professional status requirements is the prerequisite for this analysis. The financial impact of combining REPS with cost segregation depends on the property's depreciable basis, the available bonus depreciation percentage, the investor's marginal tax rate, and how effectively the taxpayer satisfies both the REPS and material participation tests.

TL;DR - Key Takeaway

REPS cost segregation converts suspended passive depreciation into current-year non-passive deductions against ordinary income. A qualifying investor can use accelerated cost segregation losses to offset W-2 wages, business profits, and other non-passive income. The real estate professional depreciation benefits are a timing advantage, not permanent tax elimination, and create depreciation recapture exposure on disposition. Suspended losses from pre-REPS years remain passive; the REPS treatment applies only in years the tests are satisfied.

Why REPS Transforms Cost Segregation

The passive activity rules under IRC Section 469 automatically classify rental activities as passive for most taxpayers. Passive losses can only offset passive income. An investor without passive income from other sources receives no current benefit from those losses - they accumulate as suspended passive losses and are released only upon a fully taxable disposition of the activity or the generation of future passive income.

Real estate professional cost segregation changes this outcome by removing the passive classification from rental activities for qualifying taxpayers. A taxpayer who satisfies REPS and material participation requirements treats rental losses as non-passive. Those losses can immediately offset wages, business income, investment income, and other non-passive income in the year they arise.

The difference between suspended passive losses and usable non-passive losses is the difference between a deferred benefit and an immediate one. Given the time value of money, this transformation is often the single most important variable in the economics of a cost segregation engagement for high-income investors.

Passive Loss Rules Without REPS

For investors who do not qualify as real estate professionals, rental losses from cost segregation are passive. These losses cannot be used to reduce W-2 income, self-employment income, or business profits. The only exception for non-qualifying investors is the $25,000 rental loss allowance under Section 469(i), which phases out between $100,000 and $150,000 of adjusted gross income.

An investor with $300,000 of AGI who does not qualify as a real estate professional receives zero current-year benefit from $200,000 of cost segregation losses. Those losses are suspended and will only generate a tax benefit when the investor sells the property, acquires passive income from other sources, or eventually qualifies as a real estate professional in a future year.

Cost segregation studies are still performed by investors who do not qualify for REPS, but the investment case is different. For a comparison of the value of cost segregation under both scenarios, see the analysis of cost segregation without real estate professional status.

REPS Cost Segregation Mechanics

The mechanics work in three steps. First, a qualifying cost segregation study reclassifies building components from 27.5 or 39-year property to 5, 7, or 15-year property (and in some cases land improvements). Second, the reclassified components generate accelerated depreciation under MACRS, or immediate expensing under bonus depreciation. Third, because the taxpayer qualifies as a real estate professional and materially participates, those depreciation deductions are non-passive and flow through to reduce ordinary income on Form 1040.

The study itself is performed the same way regardless of the taxpayer's REPS status. What changes is how the resulting deductions are classified and used on the tax return. The same cost segregation report that produces passive losses for a non-qualifying investor produces non-passive deductions for a qualifying real estate professional.

Real Estate Professional Depreciation: Scale of Benefit

The scale of real estate professional depreciation benefits depends primarily on the property's depreciable basis and the percentage of that basis that can be reclassified to shorter recovery periods. For a typical commercial building, cost segregation might reclassify 20 to 40 percent of the depreciable basis to personal property and land improvements qualifying for accelerated treatment.

Property Value	Depreciable Basis	Reclassified (30%)	First Year Deduction (100% Bonus)	Tax Savings (37%)
$1,000,000	$800,000	$240,000	$240,000	$88,800
$3,000,000	$2,400,000	$720,000	$720,000	$266,400
$5,000,000	$4,000,000	$1,200,000	$1,200,000	$444,000

These figures represent maximum theoretical savings when 100% bonus depreciation is available and the full reclassified amount is deductible against non-passive income. Actual results vary based on bonus depreciation rates in the applicable year, the property type, and the taxpayer's overall tax position.

Cost Segregation With REPS and Bonus Depreciation

The combination of cost segregation with REPS and bonus depreciation has been one of the most impactful strategies available to qualifying real estate investors in recent years. Bonus depreciation phases down from 100% in 2022 to 80% in 2023 and continues declining by 20 percentage points per year under current law, though legislative changes may modify this schedule.

When bonus depreciation is available, the reclassified short-life assets can be fully expensed in year one rather than depreciated over 5, 7, or 15 years. This concentrates the deduction into a single tax year, maximizing the current-period benefit for investors who need to offset income in a high-tax year.

As bonus depreciation rates decline, the annual deduction from cost segregation decreases, though the study still generates accelerated depreciation relative to straight-line. The REPS benefit remains meaningful even as bonus depreciation phases out.

REPS Tax Savings Calculation

Calculating REPS tax savings from a cost segregation engagement involves three inputs: the non-passive depreciation deduction generated, the taxpayer's marginal federal income tax rate, and the applicable state income tax rate.

The calculation is straightforward: multiply the non-passive deduction by the combined marginal rate. A $400,000 non-passive deduction for an investor in the 37% federal bracket with 5% state taxes generates approximately $168,000 of combined tax savings in the year of deduction. This ignores recapture and assumes full absorption of the deduction against other income.

Investors should compare these projected savings against the cost of the study and the cost of qualifying for and maintaining REPS status. For a broader framework on evaluating cost segregation return on investment, the analysis should incorporate the recapture exposure on sale and the opportunity cost of the study fee.

Suspended Passive Losses and REPS

An investor who qualifies as a real estate professional for the first time in a given year cannot retroactively apply REPS treatment to losses from prior years. Losses that were suspended as passive in years before REPS qualification remain suspended. They are not released simply because the investor now qualifies.

The suspended losses will eventually become deductible when the investor has sufficient passive income, or upon a fully taxable disposition of the activity. Planning around the release of these suspended losses is an important element of the overall investment and tax strategy for investors who transition into real estate professional status after years as a passive investor.

Depreciation Recapture Considerations

Cost segregation accelerates depreciation, and accelerated depreciation creates a larger recapture liability on disposition. Personal property (5- and 7-year assets) is subject to Section 1245 recapture, taxed as ordinary income at rates up to 37%. Land improvements (15-year assets) are also typically subject to Section 1245 treatment for portions accelerated via bonus depreciation.

Investors who benefit from REPS cost segregation in the year of acquisition and then sell the property within a few years may find that much of the tax saved via accelerated depreciation is recaptured on sale. The net benefit depends on the holding period, the change in marginal rates between the deduction year and the sale year, and the availability of installment sale or like-kind exchange planning.

REPS and Net Investment Income Tax

The 3.8% net investment income tax (NIIT) under IRC Section 1411 applies to passive income and passive losses. When rental income is passive, it is generally subject to NIIT. When a real estate professional treats rental income as non-passive because of REPS status and material participation, that income may escape NIIT classification, depending on the facts.

This is an additional benefit of REPS qualification that is often overlooked in planning discussions. Investors with significant rental income who qualify as real estate professionals should analyze their NIIT exposure as part of the overall tax planning around the REPS qualification.

Spouse REPS and Cost Segregation Planning

On a joint return, one spouse's real estate professional status can make rental losses non-passive for purposes of the joint return when that spouse also materially participates in the rental activities. This allows a family unit where one spouse qualifies for REPS to use cost segregation losses against the other spouse's wages or business income.

The mechanics and planning considerations for this scenario are covered in the analysis of a spouse qualifying for real estate professional status. The interplay between spousal qualification, material participation, and cost segregation requires careful coordination with a tax advisor familiar with both the passive activity rules and cost segregation mechanics.
