K-1 vs. 1099-DIV: How Real Estate Investments Are Taxed

The first piece of mail many investors who are new to private real estate don't expect is a state tax return for somewhere they've never set foot. Indiana, say, or South Carolina. They open it, blink at it, and call their CPA on a Saturday. The CPA, who has been through this before, exhales patiently and explains that they'll be fine — that's just how a JV partnership works.  

The form on the doorstep is a Schedule K-1. You may have invested in something called a syndication or a private fund, and you may have grown used to a particular kind of paperwork from your brokerage: neat 1099s, arriving on schedule, easy to hand to your tax software and forget. The K-1 is not that. The K-1 is what happens when the tax code treats you as a co-owner of the building, because, in a real and useful sense, you are one.

That difference is not clerical. A Schedule K-1 means you own a share of a partnership, so the property's depreciation flows through to your own tax return and can shelter part of your distributions from current tax. A Form 1099-DIV means you own shares of a corporation, usually a REIT, which uses that depreciation itself before it pays you. Same asset class, often the same kind of building. Which form arrives in your mailbox depends on which side of the depreciation you sit, and that determines how much of every distribution you keep.

K-1 vs. 1099-DIV: What Each Tax Form Is

What Is a Schedule K-1?

A Schedule K-1 is the tax form a partnership, or an LLC taxed as one, sends each partner every year to report that partner's share of the business's income, deductions, credits, and depreciation. For real estate partnerships, the form is Schedule K-1 (Form 1065). The partnership itself pays no federal income tax. Its tax items pass through to the partners in proportion to their ownership, and each partner reports them on their own return.

Most direct real estate syndications, including the single-asset deals we do at Lightstone DIRECT, are partnerships, which is why our investors get K-1s.  For a calendar-year partnership, K-1s are due to partners by March 15, or by September 15 if the partnership extends its return, which many real estate partnerships do.

What Is Form 1099-DIV?

Form 1099-DIV is the tax form a corporation, mutual fund, or REIT sends shareholders to report the dividends and distributions it paid them during the year. A REIT is a corporation that generally avoids entity-level tax by distributing at least 90% of its taxable income, but it still calculates that income, depreciation included, at the entity level. Shareholders see the result, broken into categories such as ordinary dividends, capital gain distributions, and return of capital, rather than the underlying mechanics.

Listed REITs like AvalonBay and Equity Residential issue 1099-DIVs, as do non-traded REITs like BREIT, SREIT, and Ares REIT. Most accredited investors will, over a long enough career, hold both. The difference that matters most is what each form does to the after-tax math.

Where Depreciation Lands

The biggest difference between the two forms is depreciation.

The IRS lets you depreciate real estate on the theory that a building wears out over 27.5 years (residential) or 39 years (commercial), even if the building is, in fact, doing perfectly well and gaining market value. That fiction generates a paper loss every year. On a $50 million multifamily property with $40 million of depreciable basis, straight-line depreciation alone is roughly $1.45 million per year. Add a cost segregation study, which carves out personal-property components that depreciate over 5, 7, or 15 years and front-loads those deductions, and the first-year depreciation can be considerably larger.  

Where that deduction lands is what separates a K-1 from a 1099-DIV.  

In a partnership, depreciation flows through to the partners. You get your share, on your K-1, as a paper loss. That loss could offset some or all of the cash distribution you received, so the cash that hits your account in the early years may be partly or fully tax-deferred in the year of receipt. One caveat that matters: under the passive activity loss rules, these losses can generally only shelter passive income, unless you qualify as a real estate professional — a status that most accredited investors don't have and shouldn't try to manufacture. The deferred tax also doesn't vanish; when the property eventually sells, the accumulated depreciation is "recaptured" at a federal rate of up to 25% on the portion of the gain attributable to it. But you have had years of cash flow that, in tax terms, looked a great deal smaller than it actually was.  

In a REIT, depreciation gets used at the entity level. The REIT subtracts it from its own income before deciding what to pay out. You, as a shareholder, never see it. You see a distribution on your 1099-DIV, a portion of which is labeled "ordinary dividends" and taxed at your marginal income rate. REIT ordinary dividends are not "qualified dividends," by the way; the preferential 20% rate that applies to most corporate dividends does not apply here, because REITs don't pay corporate tax in the first place and so the double-taxation argument that justifies the lower rate falls away. Other portions of your distribution may be classified as "return of capital," which reduces your cost basis instead of being taxed immediately, or as "capital gain distribution," taxed at long-term rates. The Section 199A deduction lets shareholders deduct up to 20% of qualified REIT dividends, a provision the One Big Beautiful Bill Act made permanent in 2025. That narrows the gap: at the top federal bracket, it brings the effective rate on those dividends to about 29.6%. But it is a deduction against income you have already received, not a loss that shelters it.

So: same asset class, same underlying depreciation. In one structure, it shelters you. In the other, it shelters the issuer.

The Friction of a K-1

The K-1 form has pluses and minuses. The tax advantage is real; the friction is also real; depending on the rest of your situation, either form can be the more welcome one to receive in the mail.

‍

• ‍K-1s are more likely to arrive late. A well-run sponsor will have K-1s out by early March, but plenty don't, and the IRS extension is essentially built into private real estate. If you hate filing for extensions, you will mildly resent your sponsor every spring. This issue may be exacerbated by third-party syndication (or “real estate crowdfunding”) platforms; despite the best intention, the platform may be relying on the sponsor to provide documentation, then conduct reconciliation before finally distributing tax docs to investors. While we cannot make a blanket promise, Lightstone DIRECT is well equipped to deliver K-1s on time: we are a vertically integrated firm, directly managing the investment, and employ in-house accounting professionals across numerous lines of business, including Lightstone DIRECT.‍
• K-1s mean multi-state filings. If the partnership's property sits in a state with an income tax — most of them — and you live somewhere else, congratulations: you owe a return in the state where the property sits, too. Composite filings can simplify the mechanics. They don't eliminate them.‍
• K-1s mean illiquidity. You cannot sell out of a private partnership the way you can sell shares of a listed REIT. The cash you receive is real, but the underlying position is locked up for the hold period. For most Lightstone DIRECT offerings, this hold period is most often four-six years.

‍

K-1-bearing investments are generally best for accredited investors who already have meaningful passive income (from existing rental real estate, business interests, or other syndications) and who have a competent CPA capable of absorbing the additional complexity without breaking a sweat. For the investor whose tax preparer still faxes things, K-1 friction can eat into the tax advantage on its own. Lightstone strives to conduct a compliant and thorough cost segregation study for each Lightstone DIRECT asset, which can meaningfully benefit investors with preexisting passive income.

Where the 1099-DIV Earns Its Keep

A 1099-DIV is simpler. One form, one set of state returns (yours), and — at least for listed REITs — shares you can sell on a Tuesday afternoon. For the portion of a portfolio that genuinely needs to be liquid and low-friction, listed REITs provide real utility. They aren't a tax-efficiency win, but tax efficiency isn't the only thing portfolios optimize for.  

When I received my first K-1 from a real estate investment, years ago, I read it once, understood roughly a third of it, and put it in a folder marked TAX. I called my accountant in a small panic. He told me to relax, and to expect three more before the year was out. He was right. The form is unfamiliar at first, and the multi-state filing in particular feels like a small bureaucratic insult. But once you have spent a year or two with it, it stops being a nuisance and starts being a tool. The depreciation that flows through to you is one of the most powerful provisions in the U.S. tax code for high-income earners, and it only flows through if you co-own the asset — which is exactly what a K-1 tells you: that you do.

The Question to Ask Before You Subscribe

If there is one practical takeaway: when you compare one real estate investment to another, look at the tax form you will receive, not just the headline yield. Depending on your situation, a 5% distribution that arrives on a K-1 with a paper loss attached is not the same investment as a 5% distribution that arrives on a 1099-DIV taxed at your marginal rate. The cash hits the same account. The math underneath, as pertains to post-tax returns, is different.  

In one case, you are a shareholder of a corporation that happens to own real estate. In the other, you are, in a real and useful sense, a co-owner of the building. The form on your doorstep tells you which.
