Tax Benefits of Commercial Real Estate: Depreciation, K-1s, and Deferral

What are the tax benefits of commercial real estate? They are a set of provisions in the Internal Revenue Code that let a property owner deduct the cost of a building over time, pass those deductions through to individual investors, and defer tax on gain when the property is sold. Four mechanisms do nearly all of the work: depreciation, cost segregation with bonus depreciation, the partnership Schedule K-1 that carries an investor's share, and deferral tools such as the Section 1031 exchange. None of them is a loophole. Each is a timing rule with its own limits.

Those limits are where most of the confusion lives. A deduction that appears on a tax form is not automatically a deduction on a return, and tax deferred is not tax avoided. This guide covers where each benefit comes from, how it reaches a passive owner, what stops it, and what arrives at the end of the hold. Readers newer to the asset class may want to start with how commercial real estate investing works.

Key Takeaways

• Depreciation is the core benefit: the tax code allows a deduction for part of a building's cost each year even while the property holds its value.
• Nonresidential real property is depreciated straight line over 39 years, and land is never depreciable, so the purchase price has to be allocated first.
• Cost segregation and bonus depreciation change when deductions are taken, not how many exist in total. Pulling them forward raises the recapture question later.
• A fund investor receives a Schedule K-1 rather than a Form 1099, and depreciation often makes the reported figure a loss in a year when cash was distributed.
• Passive activity rules generally stop a rental loss from offsetting wages, so a paper loss on the form is not automatically a deduction on the return.
• A 1031 exchange defers gain on a property sale, but it is deferral rather than forgiveness, and it applies to real property rather than to partnership interests.

Why Depreciation Is the Engine

Depreciation is the largest tax benefit in commercial real estate because it is a deduction that requires no spending in the year it is claimed. The tax code treats a building as an asset that wears out over a fixed period, so the owner deducts a portion of its cost every year, including years in which the property is fully leased and gaining value.

Two allocation rules shape the size of that deduction. Land is not depreciable, because land does not wear out, so the purchase price has to be split between land and improvements before anything is calculated. Only the improvement portion generates deductions, which means a property in an expensive land market produces a smaller depreciation deduction than an identical building sitting on cheaper dirt.

The recovery periods are set by statute rather than by judgment. Under the Modified Accelerated Cost Recovery System, nonresidential real property is depreciated straight line over 39 years using a mid-month convention, and residential rental property over 27.5 years. In a hypothetical purchase where $3.9 million of the price is allocated to the building, the annual deduction is $100,000, which is one thirty-ninth of the allocated basis, deducted the same way every year until the schedule runs out.

The practical result is the central fact of real estate taxation. A property can collect rent, service its debt, distribute cash, and still report a loss for tax purposes, because a large deduction ran through the calculation without any money leaving the bank account. Investors sometimes call this a paper loss, and whether it can actually be used is a separate question covered further down.

Lease structure does not change any of this. In a net lease, the tenant pays operating costs directly, which affects the property's cash flow but not the depreciation schedule of the building the owner holds. The mechanics of that cost allocation are covered in the guide to how triple net lease structures assign operating expenses.

Cost Segregation and Bonus Depreciation: Pulling Deductions Forward

Cost segregation is an engineering-based study that separates a building into components with shorter depreciable lives instead of treating the whole structure as one 39-year asset. Items such as specialty electrical, certain fixtures, carpeting, signage, parking areas, and landscaping can qualify for 5, 7, or 15-year treatment, which moves deductions from the distant future into the early years of ownership.

Bonus depreciation is what makes that reclassification powerful, because it allows an immediate deduction for a percentage of qualifying shorter-lived property in the year it is placed in service. The percentage has changed repeatedly. IRS Publication 946 states that P.L. 119-21, commonly known as the One Big Beautiful Bill Act, reinstated the 100% special depreciation allowance for certain qualified property acquired and placed in service after January 19, 2025, with an election available to take a reduced allowance instead for the first tax year ending after that date. Property acquired earlier falls under the phase-down percentages that applied in its own year, which is why two acquisitions in the same portfolio can be treated differently.

Qualified improvement property, a defined category of interior improvements made to an existing nonresidential building, has its own rules and is a common subject of these studies. Whether a specific improvement qualifies is a technical determination rather than an assumption.

Two honest caveats belong with all of this. First, cost segregation does not create deductions that did not exist. It reorders them. The total depreciation available over the life of the asset is the same, so the benefit is the time value of taking it sooner, and a study has a real cost that has to be weighed against that. Second, accelerating deductions into the early years makes the reported loss larger in exactly the years when an investor may have the least capacity to use it, and it changes the character of gain at sale. Both of those consequences arrive later, and both are covered below.

How the Benefit Reaches a Passive Investor

An individual who does not own property directly reaches these deductions through a pass-through entity. Private real estate funds and syndications are typically organized as limited partnerships or LLCs taxed as partnerships, and a partnership pays no federal income tax itself. It files Form 1065 and allocates each item of income, deduction, and credit to its partners, who report them on their own returns.

The delivery vehicle is Schedule K-1. Instead of the Form 1099 a brokerage sends, each investor receives a K-1 reporting a share of what the entity earned, spent, and depreciated, whether or not any cash was distributed. Net rental real estate income or loss appears in Box 2, distributions appear separately in Box 19, and the two numbers routinely disagree. That disagreement is the depreciation effect described above, not an error.

One feature of the pass-through structure is worth naming because it is genuinely favorable. Items retain their tax character on the way through, so rental income stays rental income, interest stays interest, and capital gain stays capital gain rather than arriving as one blended figure. That is why the form has so many boxes, and why a preparer spends most of the time on the coded items rather than on the obvious ones.

Timing is the other feature, and it surprises first-year investors. Calendar-year partnerships face a March 15 deadline for Form 1065 and can extend six months to September 15, so a K-1 frequently arrives after an individual would otherwise have filed. Extending a personal return is ordinary in this asset class rather than a signal that something went wrong, and an extension of time to file is not an extension of time to pay. The form itself, box by box, is covered in the guide to reading a Schedule K-1 from a real estate fund.

The Limits: Passive Losses, Basis, and At-Risk

A loss reported on a K-1 is not automatically deductible. Three separate limits sit between the form and the return, and each one is applied at the investor level rather than at the fund level, which is why two people holding identical interests can get different results from the same allocation.

The passive activity rules come first and bite hardest. IRS Publication 925 treats rental activities as passive even where the taxpayer materially participates, unless the taxpayer is a real estate professional, and it states that generally the passive activity loss for the tax year is not allowed. A passive loss ordinarily offsets passive income rather than wages or portfolio income, and unused amounts are suspended and carried forward. They are generally released when the entire interest in the activity is disposed of.

Two exceptions get more attention than they deserve for passive fund investors. The special allowance permits up to $25,000 of loss from rental real estate in which the taxpayer actively participated to offset nonpassive income, but it is reduced by 50% of modified adjusted gross income above $100,000 and disappears entirely at $150,000. Limited partners generally do not meet the active participation standard in the first place. Real estate professional status is the other, and Publication 925 requires both that more than half of the personal services performed in all trades or businesses be in real property trades or businesses in which the taxpayer materially participated, and that more than 750 hours of such services be performed during the year. A physician or attorney working full time in that profession will not clear the first test.

Basis and at-risk limits come next and are easy to overlook. A loss is not deductible beyond an investor's adjusted tax basis in the partnership interest, and the at-risk rules impose a separate ceiling. Basis starts with the amount invested, rises with allocated income and contributions, and falls with allocated losses and distributions. The capital account shown on a K-1 resembles basis and is not the same figure.

Deferral at Sale, and What Recapture Takes Back

Two things happen at the end of a hold that determine whether the earlier benefits were real or borrowed. An owner selling real property may defer gain through a Section 1031 like-kind exchange, and any owner who claimed depreciation faces recapture on the deductions already taken. They pull in opposite directions and are best understood as one question.

The 1031 rules are procedural and strict. Since the Tax Cuts and Jobs Act, Section 1031 applies only to exchanges of real property, and the IRS notes that real property in the United States is not like-kind to real property outside the United States. The replacement property must be identified in writing no later than 45 days after transferring the relinquished property, and received by the earlier of the 180th day after that transfer or the due date of the return, including extensions, for the year of the transfer. Because the seller cannot take receipt of the proceeds without defeating the exchange, these transactions are ordinarily administered through a qualified intermediary. Cash or other non-like-kind consideration received in the exchange, commonly called boot, triggers recognized gain to that extent.

One point matters specifically for fund investors and is regularly misunderstood. A 1031 exchange is executed by the entity that owns the real property. An interest in a partnership is not real property, so an investor holding a limited partner interest generally cannot exchange that interest for another one, and whether a fund exchanges at the asset level is a decision made by the sponsor under the governing documents.

Recapture is the bill for the deductions. Depreciation claimed on the building is accounted for at sale as unrecaptured Section 1250 gain, which the IRS states is taxed at a maximum 25% rate rather than at the long-term capital gains rate. Shorter-lived components identified in a cost segregation study are generally Section 1245 property, and depreciation on those is typically recaptured as ordinary income. That is the trade embedded in accelerating deductions: a deduction taken today against ordinary income can come back as ordinary income later, so the benefit is timing and rate arbitrage rather than permanent savings.

What These Benefits Do Not Do

The most common error in this area is treating a tax benefit as a return. Depreciation reduces taxable income. It does not produce cash, improve a property's operations, or make a weak tenant creditworthy. A property that loses money economically and generates deductions has still lost money, and a deduction is worth the marginal rate it offsets rather than its face amount.

Deferral is not forgiveness. A 1031 exchange moves basis into the replacement property and carries the deferred gain forward, so each exchange lowers basis and increases the potential gain in the next transaction. Rules exist that can change the outcome when property is held until death, and those rules have their own requirements and have been the subject of repeated legislative proposals. That is an estate planning question for an attorney and a tax advisor rather than a feature to be assumed.

Several other items land on real returns and are routinely missed. A fund that owns property in multiple states can create nonresident filing obligations for its partners, turning a single return into several. Investment income above statutory thresholds can attract the additional 3.8% net investment income tax. Suspended passive losses can sit unused for years before a disposition releases them. And the figures that matter most, including basis, marginal rate, residency, and other passive income available to absorb a loss, are all facts about the investor rather than facts about the property.

That is the reason every specific answer in this area has to be worked out individually. Freedom Commercial Real Estate does not provide tax advice, and nothing here is tax advice. Anyone weighing how depreciation, a K-1 allocation, or a deferral strategy would actually affect their return should work through it with their own CPA or tax advisor, because the answer genuinely changes from person to person.

Frequently Asked Questions

Q: Can commercial real estate losses offset my W-2 income?

A: Usually not. IRS Publication 925 treats rental activity as passive, and passive losses generally offset passive income rather than wages, with unused amounts suspended and carried forward until there is passive income to absorb them or the interest is disposed of. The $25,000 special allowance phases out between $100,000 and $150,000 of modified adjusted gross income and generally requires active participation, which limited partners typically do not have.

Q: Is 100% bonus depreciation still available?

A: Publication 946 states that the One Big Beautiful Bill Act reinstated the 100% special depreciation allowance for certain qualified property acquired and placed in service after January 19, 2025, with a reduced-percentage election available for the first tax year ending after that date. Property acquired before that falls under the phase-down percentage for its own year, so the answer depends on when a specific asset was acquired and placed in service.

Q: What is depreciation recapture and when does it apply?

A: It is the accounting for depreciation already deducted, and it applies at sale. Depreciation on the building is treated as unrecaptured Section 1250 gain, taxed at a maximum 25% rate rather than the long-term capital gains rate. Depreciation on shorter-lived components identified through cost segregation is generally Section 1245 property and is typically recaptured as ordinary income, which is the cost of having accelerated those deductions.

Q: Can I do a 1031 exchange with my interest in a real estate fund?

A: Generally no. Section 1031 applies to exchanges of real property, and a limited partner interest in a partnership is not real property. The exchange, if one happens, is done by the entity that owns the asset, under the terms of the governing documents. Because that answer turns on the specific entity, your own holding period, and your basis, it is a question for your own CPA or tax advisor rather than one with a universal answer.
