When a real estate syndication performs a cost segregation study, the accelerated depreciation flows through to investors on Schedule K-1, often producing a large first-year paper loss. Whether you can actually use that loss against your other income is a separate question from whether it appears on your K-1. For most limited partners, the loss is passive and can generally only offset passive income, not wages or business profit. It is not lost, it carries forward, and it typically becomes usable when the property is sold. Understanding this before you invest changes how you evaluate the deal.
An orthopedic surgeon in Sioux Falls, South Dakota invested $200,000 in an apartment syndication. The sponsor's materials had highlighted the tax benefits prominently, including a cost segregation study planned for year one. When the K-1 arrived the following spring, it showed a loss allocation of roughly $150,000.
He was thrilled. He earns a high income, he is in the top bracket, and a $150,000 deduction against that income would be worth a great deal. He forwarded the K-1 to his CPA expecting good news.
His CPA called back with a more complicated answer. The $150,000 was real. It was correctly calculated and properly reported. But he could not use it against his surgical income. It was a passive loss, he had essentially no passive income, and so the deduction sat suspended, carrying forward to some future year.
He had not been misled. The sponsor never claimed the loss would offset his wages. But nobody had explained the distinction either, and he had assumed a deduction was a deduction. This article explains what he wishes someone had told him before he wired the money.
Start with the mechanics, because they are actually straightforward.
A syndication buys a property, typically through a partnership or an LLC taxed as a partnership. The entity, not the individual investors, owns the real estate. When the sponsor commissions a cost segregation study, the study is performed on the property at the entity level. It identifies components of the building that qualify for shorter recovery periods than the building structure itself.
The resulting accelerated depreciation is a deduction of the partnership. Partnerships generally do not pay federal income tax themselves. Instead, items of income, deduction, gain, and loss pass through to the partners and are reported to each partner on Schedule K-1. Your share of the depreciation, determined by the partnership agreement and the allocation provisions in it, shows up on your K-1.
With 100 percent bonus depreciation restored permanently by the One Big Beautiful Bill Act, signed into law on July 4, 2025, for qualifying property placed in service after January 19, 2025, the reclassified components can generate a very large first-year deduction. Spread across investors, that produces exactly the eye-catching K-1 the surgeon received.
So far, so good. The complication is not in how the loss is generated. It is in what you are permitted to do with it.
The tax code sorts your activities into buckets, and the boundary that matters here is between passive and non-passive.
Rental real estate activity is generally treated as passive by default. On top of that, a limited partner in a syndication is typically not materially participating in the business. You wired money, you receive reports, you attend an annual call. The sponsor makes the operating decisions. Under the material participation rules, that ordinarily makes your interest passive.
The consequence is the rule that surprised the surgeon. Passive losses can generally only offset passive income. They generally cannot offset wages, salary, business income you actively earn, or portfolio income like interest and dividends. If you have no passive income, a passive loss has nothing to absorb it in the current year.
The loss does not vanish. It becomes a suspended passive loss, carried forward indefinitely, waiting for passive income to offset or for a disposition that frees it. But waiting is not the same as using, and the time value difference is real. A deduction you take this year is worth meaningfully more than the same deduction taken in year six.
There are several paths, and which apply depends heavily on your facts. This is your CPA's territory, but you should know the terrain.
Other passive income. The most direct route. If you hold other investments generating passive income, suspended passive losses can offset it. Investors with a portfolio of syndications sometimes find that losses from newer deals offset income from stabilized older ones. This is part of why experienced passive investors think about their holdings as a portfolio rather than as isolated deals.
Disposition of the activity. Generally, when you dispose of your entire interest in a passive activity in a fully taxable transaction, the suspended losses attributable to that activity are freed. In practice, for many syndication investors, this is when the benefit finally lands: the property sells, the deal winds up, and the suspended losses come loose to offset the gain and potentially other income. The deduction was not lost, it was deferred to the exit.
Real estate professional status. Qualifying as a real estate professional can change the character of rental activity, but the requirements are demanding and involve substantial time spent in real property trades or businesses in which you materially participate. A full-time surgeon is not going to qualify on the strength of a passive syndication interest. For genuine real estate professionals, the analysis is different and worth having.
The short-term rental treatment. Certain short-term rental arrangements are treated differently under the rules than typical long-term rentals, which can affect the passive characterization. Whether it applies depends on specific tests and facts, and it is its own detailed topic.
None of these are things you can decide unilaterally after the K-1 arrives. They depend on your overall tax situation, and several depend on facts established long before the K-1 was issued.
Put figures on it, because the honest math is more useful than either the sponsor's optimism or the surgeon's disappointment.
He invested $200,000 and received a $150,000 first-year loss allocation. If that loss had been usable against his ordinary income at a 37 percent marginal rate, it would have been worth about $55,500 in reduced tax in year one. That is the number he had in his head.
Because the loss was passive and he had no passive income, the actual year-one tax benefit was zero. The $150,000 became a suspended loss.
Now, is the deal bad? No, and this is where a fair analysis matters. The suspended loss is still an asset. When the property sells in, say, year six, the suspended losses are generally freed and can offset the gain from the sale, reducing the tax on his exit. He also received cash distributions along the way, which the depreciation sheltered at the entity level, meaning those distributions may have come to him without current tax. The tax benefit is real. It simply arrives later and in a different form than he expected.
Keith Cunningham's framing is the useful one. The deal did not fail. The forecast failed, because it counted a benefit in a year it could not land. The number was right and the timing was wrong, and in finance, timing is not a detail.
The lesson is not to avoid syndications. It is to evaluate the tax story accurately, which means asking questions the marketing deck usually does not answer.
Ask whether the projected depreciation benefit assumes you can use the loss currently. Many projections show a first-year deduction without addressing usability, because usability depends on the investor, not the deal. The sponsor cannot know your situation. You can.
Ask whether you have passive income to absorb the loss. If yes, the year-one benefit may be real. If no, model the benefit as arriving at disposition instead, and discount it accordingly.
Ask about the hold period. A suspended loss freed at disposition in year four is worth more than the same loss freed in year ten. The hold period is part of the tax analysis, not just the return analysis.
Ask whether the sponsor is actually doing an engineered study. A study that overreaches on classifications produces a deduction that looks impressive on the K-1 and creates exposure at the entity level, which flows to every investor. A study that underreaches leaves money unclaimed. This is a question about the quality of the sponsor's underwriting, and it is fair to ask.
If you sponsor deals, the investor-side confusion described here is your problem too, because it produces disappointed investors who felt oversold even when you said nothing untrue.
The fix is disclosure that treats investors as capable adults. State the projected entity-level depreciation, then state plainly that whether an individual investor can use the allocated loss currently depends on that investor's passive activity situation and should be discussed with their own tax advisor. Investors who understand the timing are not disappointed by it. Investors who discover it from their CPA in April feel misled.
The quality of the underlying study matters as well. Accelerated depreciation allocated to dozens or hundreds of investors is a position that has to hold up. An engineered study built under the IRS-preferred methodology, with the documentation to support it, protects every investor on the cap table. A cheap software model that overreaches puts them all in the same exposed position.
The Cost Seg America team has completed more than 16,000 studies and defended studies through more than 125 IRS audits with zero losses and zero dollars ever returned to the IRS. On a syndicated property, that defensibility is not an abstraction. It is the difference between a deduction your investors keep and one they have to give back.
Assuming a K-1 loss offsets your salary. The most common and most expensive assumption. For most limited partners, the loss is passive and cannot offset wages or active business income.
Treating a suspended loss as a lost loss. It carries forward indefinitely and is generally freed on disposition of the activity. Deferred is not destroyed.
Modeling year-one tax savings you cannot claim. If the loss will be suspended, the honest model shows the benefit at exit, discounted for time, not in year one.
Ignoring the quality of the entity-level study. Every investor inherits the entity's position. An aggressive study is a shared risk.
Waiting until the K-1 arrives to ask the question. Usability depends on facts largely fixed before you invest. Ask first.
If you are a passive investor in real estate syndications, have a conversation with your CPA about your passive activity picture before your next investment, not after the next K-1. The question is simple: do I have passive income to absorb allocated losses, and if not, when would these losses realistically become usable? The answer tells you how to value the tax component of every deal you look at.
If you are a sponsor, the Cost Seg America team performs engineered studies on syndicated properties and works with sponsors and their CPAs to make sure the entity-level position is documented and defensible for every investor on it.

Can I use the loss on my syndication K-1 against my salary?
Usually not. Rental real estate is generally passive, and a limited partner typically does not materially participate, so the allocated loss is generally a passive loss that can only offset passive income. It carries forward rather than offsetting wages.
Is the suspended loss gone?
No. Suspended passive losses carry forward indefinitely. They can offset future passive income, and generally they are freed when you dispose of your entire interest in the activity in a fully taxable transaction.
Why does the sponsor advertise big tax benefits then?
The entity-level depreciation is real, and the sponsor is reporting it accurately. Whether an individual investor can use their allocated share currently depends on that investor's own tax situation, which the sponsor cannot know. The gap is usually in expectations, not in the numbers.
Does real estate professional status help?
It can change the character of rental activity, but the requirements involve substantial time in real property trades or businesses with material participation. Passive syndication interests generally do not get you there on their own.
When do I actually get the benefit?
For many passive investors, at disposition, when suspended losses are generally freed and can offset the gain on sale. Depreciation also shelters entity-level income along the way, which can affect the tax character of distributions you receive.
How do I evaluate a deal's tax story properly?
Ask whether the projection assumes current usability, assess your own passive income, factor in the expected hold period, and ask whether the sponsor is commissioning an engineered study. Then run it past your own CPA rather than the sponsor's materials.
