721 Exchange Explained: Property, OP Units, and REIT Shares

By Jerry Baker

A 721 exchange generally lets you contribute property to a partnership for an ownership interest without recognizing gain at that time. In an UPREIT, you receive units in a REIT’s operating partnership, rather than REIT shares or another property you own directly. The tax result depends on the transaction, and the move changes your control, reporting, and future exit choices. [1] [2]

What actually changes in a 721 exchange?

Picture an owner who wants to stop managing an apartment building. A sale would turn the property into cash and could create a tax bill. A 1031 exchange could move the owner into other qualifying real estate. A 721 contribution offers a different path: the owner transfers property to a partnership and receives a stake in that partnership.

Section 721 is the tax rule. UPREIT is the ownership structure. The terms are related, but they do not mean the same thing. Section 721 can apply to many kinds of partnerships; it was not written only for REIT transactions. [1]

An UPREIT generally has a REIT above an operating partnership, or OP. The OP holds real estate directly or through other entities. Property owners who contribute assets can receive OP units. The REIT typically controls the OP and holds a large share of its units. [2]

You have moved from making decisions about one asset to owning an interest in a business run by others. That may reduce your work. It also means you cannot treat the contributed building as your own property to refinance, sell, or leave to one child apart from the rest of your investment.

My first question is not whether the structure sounds clever. It is whether you want the investment that comes after the contribution. Tax deferral cannot make a poor fit into a good one.

Real estate, OP units, and REIT shares are different assets

What you ownWhat it representsWhat to check
Direct real estateA property interestTitle, debt, leases, and authority over the property
OP unitsAn interest in the operating partnershipPartnership rights, tax allocations, and limits on transfers or redemptions
REIT sharesStock in the REITShare class, trading market or repurchase plan, and shareholder rights

These are not three names for the same thing. A unit may have an economic link to a REIT share under the documents. That does not make the unit freely tradable stock. Read the terms that apply to your exact class and transaction.

Ordinary OP units generally are not real property eligible for a 1031 exchange. REIT shares also do not qualify as direct 1031 replacement property. The regulation has narrow exceptions for certain other interests, including a partnership with a valid Section 761(a) election. That exception is not a reason to treat a typical UPREIT interest as exchangeable real estate. [3]

This change deserves attention before you invest. An owner who values another personal 1031 exchange later may prefer a different path. A future sale by the partnership does not give each unit holder a personal right to direct where the proceeds go.

How property value becomes a number of units

The contribution agreement sets the value being accepted and how many units you receive. Debt, costs, reserves, and closing adjustments can change that result. A headline property value alone does not tell you the value of your new equity stake.

Consider a simplified example, with no fees or other adjustments:

The arithmetic is $1 million divided by $25. It does not establish fair value, tax basis, or a guaranteed future sale price. It also does not tell you how the debt will be allocated for tax purposes.

I would ask how both sides of the exchange were valued. A strong price for your building is less helpful if the units you receive are also priced too high. Compare appraisals, valuation dates, transaction costs, and any conflicts when related parties set the terms.

Ask what happens if the deal changes before closing. A roof repair, loan consent fee, or change in property value could alter the final number of units. Your review should use the closing terms, not just the first proposal.

Your property still has to clear a closing review

A willing owner and an attractive building are only the start. Ask what the receiving partnership needs to approve: title, environmental reports, leases, property condition, financial records, and the proposed loan treatment. Set dates for those reviews before you rely on the transaction.

If a loan stays in place, have counsel check consent and transfer terms. If it must be paid off, get a payoff statement and ask about penalties or other charges. Do not assume that receiving units removes the lender from the process.

Make sure every owner understands the plan. A family entity may have people who want cash and others who want units. Ask your advisers how those choices would be handled, who must sign, and whether they change the tax analysis. Separate the family decision from the property's investment review. An agreement that works for one owner may not work for all of them.

Tax deferral has conditions

The general Section 721 rule covers a contribution of property in exchange for a partnership interest. It can apply to a new or existing partnership. It does not say that every transaction labeled a “721 exchange” avoids current tax. [1]

Your CPA and attorney need to review the entire deal. The questions include who owns the property, what each party receives, how debt changes, and whether part of the transaction is really a sale.

Cash or other payments tied to the contribution can raise separate tax issues. A contribution followed by a related payment may fall under the disguised-sale rules. Those rules consider the facts and timing. Waiting for a chosen date does not turn a sale into a valid tax-deferred contribution by itself. [4]

There is also an exception for contributions to a partnership treated as an investment company under the applicable rules. That is one reason your adviser must check the receiving entity’s assets and tax structure. A real estate label on a brochure does not settle the analysis. [4]

Neither the amount of cash you receive nor the number of units tells the whole tax story. Liability shifts can create taxable gain even when no cash lands in your bank account.

Why debt relief can create tax without cash

Partnership tax rules track your share of liabilities. An increase can be treated as a money contribution. A decrease can be treated as a money distribution. Those changes affect the tax basis of your partnership interest. [4]

Assume a property has a $600,000 adjusted tax basis and a $1 million loan. After the contribution, assume the properly calculated share of OP debt allocated to you is $200,000. The net debt relief is $800,000.

In this simplified case, $800,000 of deemed cash exceeds the $600,000 basis by $200,000. That can produce $200,000 of taxable gain, even without an actual cash payment. This example assumes no other basis adjustments or special rules change the result. It illustrates the mechanism; it is not a tax calculation for a particular offering. [4]

The solution is not to pick a debt number that makes the spreadsheet work. Tax allocations must follow the rules and the real transaction. Recourse and nonrecourse debt can be allocated differently. Guarantees require review of their substance and terms.

Ask for a written debt-and-basis analysis before signing. Then ask what could happen later if the OP pays down loans, refinances, sells assets, or changes your share of debt. A contribution that works on day one still needs ongoing tax planning.

Your old gain does not simply disappear

Tax basis is a separate record from market value. In general, contributed property carries its adjusted basis into the partnership, subject to applicable adjustments. Your basis in the partnership interest also follows tax rules; it does not simply equal the value printed on your account statement. [4]

The difference between property value and tax basis at contribution is often called built-in gain. Partnership allocations must account for that difference. If the OP later sells the property in a taxable transaction, gain tied to your contribution can be allocated to you even if you still hold all your units. [4]

That is an important limit on the phrase “hold the units and keep deferring.” Keeping your units does not prevent every possible taxable event inside the partnership.

Some transactions include a tax protection agreement. Such a contract may require a payment if a covered action triggers specified taxes during a stated period. It is not a promise from the IRS. For example, Gladstone Commercial’s 2025 annual report discusses possible future tax protection agreements while stating that none were then in place. That illustrates why the actual contract matters more than a generic UPREIT description. [5]

If protection is offered, ask which actions are covered, when protection expires, what exceptions apply, and who must pay. Have counsel review the remedy and the payer’s ability to honor it. Do not assume a payment right gives you a veto over a sale.

Income and tax reporting after the contribution

An OP taxed as a partnership generally passes income, deductions, gains, and losses through to its partners. Partners normally receive Schedule K-1 information. That is different from owning REIT stock and receiving shareholder tax reporting. [4]

Cash distributions and taxable income are not the same measure. You may owe tax on income allocated to you even if the OP keeps the cash. A cash distribution can also have a different tax result depending on basis and the relevant rules. Do not budget taxes by multiplying your monthly deposit by a single guessed rate. [4]

Ask for the expected reporting schedule, state information, and contact for tax questions. Your CPA will need contribution records, basis history, debt allocations, and annual statements. Keep these records together from the start.

I also want to know how distributions are funded and what could reduce them. A stated payment rate does not answer whether rents cover expenses, debt service, and reserves. Review the portfolio and the cash plan rather than treating distributions as guaranteed income.

When can you turn OP units into cash?

The answer comes from the documents. Read the holding period, notice rules, transfer limits, valuation method, and who can choose cash or shares. A right to request redemption is not necessarily a right to receive cash on the day you want it.

For one concrete example, Gladstone Commercial’s 2025 report describes a one-year mandatory holding period for its OP units, other restrictions, and the company’s option to settle redemptions with common shares. Those are that issuer’s reported terms. They do not establish a universal one-year rule or a universal conversion ratio for all UPREITs. [5]

Then look at the shares themselves. Publicly traded REIT shares have a market price and trade on an exchange. Non-traded REIT shares do not offer the same open-market access. Registration with the SEC does not mean shares are exchange-listed. [6]

For any repurchase plan, read its caps, pricing, eligibility rules, and suspension rights. Keep OP redemption terms separate from REIT share repurchase terms. Moving from one instrument to another may add a second set of limits.

A taxable redemption or exchange may bring deferred gain into income. Selling shares received can have further tax consequences. The result depends on basis, debt relief, transaction form, and other facts. Have your CPA estimate the after-tax amount before treating a redemption request as spending money. [4]

How a DST can fit before a 721 contribution

A Delaware statutory trust, or DST, may be part of a two-stage plan. First, an investor completes a 1031 exchange into a qualifying DST interest. Later, the property interests may be contributed to an OP under a separate transaction intended to qualify under Section 721.

The IRS’s DST ruling treats owners as holding interests in the underlying real estate only under the described facts. It does not approve every DST, every offering, or every later contribution. Both stages need their own review. [7]

The first stage still has 1031 requirements. A standard deferred exchange generally requires written identification within 45 days and completion within 180 days, or the tax return due date including extensions if sooner. The later 721 plan does not erase those first-stage deadlines. [8]

A direct Section 721 property contribution does not acquire those 45- and 180-day deadlines merely because people call it an exchange. Its contractual closing conditions and other tax rules still matter. Keep the two sets of requirements separate. [1] [8]

Read who controls the later choice. Does each investor decide, does the sponsor have an option, or do the documents require investors to participate when stated conditions occur? “Optional” is incomplete unless it says whose option it is.

Also ask what happens if the contribution never occurs. You should understand the DST as a stand-alone investment, including its property, debt, cash flow risks, and possible exits. A hoped-for next step is not a substitute for a workable first investment.

What you gain, and what you give up

An OP interest may offer access to a larger portfolio and professional management. But owning more buildings through one platform does not eliminate risk. You remain exposed to that platform’s debt, markets, managers, costs, and decisions.

I would compare the proposed portfolio with what you already own. A large apartment portfolio may still add to your existing apartment exposure. A national name may hold assets in markets facing similar problems. Count the actual exposures, not just the number of properties.

Review fees at each level. There may be property costs, management fees, financing costs, transaction charges, and share-class expenses. Ask which figures are already reflected in projected distributions so you do not subtract them twice—or miss them entirely.

Consider control as carefully as cost. Which decisions need unit-holder approval? Can terms change? Who resolves conflicts between contributors and REIT shareholders? What information will you receive, and what rights will you have if you disagree?

A useful comparison includes keeping the property, a taxable sale, a qualifying 1031 exchange, and the proposed contribution. Compare after-tax cash, future flexibility, work required, concentration, and risk. The lowest tax bill today is only one part of that decision.

Estate planning still needs its own review

Units may be easier to divide among heirs than a single building, but transfer rights and estate documents still matter. Confirm how a trust, estate, or beneficiary can hold the units and what paperwork the issuer will need.

Inherited property generally receives a basis tied to its value under the applicable estate rules, subject to exceptions. That value can be lower as well as higher than the prior basis. Inherited partnership interests also involve a distinction between the heir’s basis in the interest and the partnership’s basis in its assets. [9] [4]

A partner’s death does not automatically reset every underlying asset’s basis. A partnership election or another applicable rule may be relevant. Avoid a blanket promise that all tax disappears if you hold units until death. Your estate attorney and CPA need the partnership terms and tax records to assess the actual result. [4]

What I would ask for before signing

Bring the proposed contribution agreement, partnership agreement, offering documents, valuation support, loan terms, and any tax protection contract to your advisers. A short marketing summary is useful for orientation. It is not enough to judge the transaction.

Build a one-page decision sheet with five answers: what you contribute, what you receive, which taxes may arise now, which choices you lose, and how you could exit. List unanswered questions beside the person responsible for resolving them.

Then test the plan against a less friendly outcome. What if distributions fall, a redemption is delayed, or your household needs cash sooner? Keep a separate liquid reserve instead of relying on a future exit that you cannot control.

The goal is a decision you understand. If the numbers work only when every assumption goes your way, I want to know that before you hand over the property.

Frequently asked questions about 721 exchanges

Do I receive REIT shares in a 721 exchange?

In a typical UPREIT contribution, you receive operating partnership units. A later redemption may involve cash or REIT shares under the documents. Units and shares have different rights and tax treatment; they should not be described as interchangeable. [2]

Is a 721 contribution always tax-free?

No. The general rule allows nonrecognition for qualifying property contributions, but debt relief, sale features, investment-company rules, and other facts can create current tax. Deferral also does not mean the gain is erased. Review the full transaction with your tax adviser. [1] [4]

Can I use OP units in my next 1031 exchange?

Ordinary OP units generally do not qualify as 1031 real property. REIT shares do not qualify either. Do not assume that owning real estate through a partnership gives you the same exchange rights as directly owning the property. [3]

Can tax arise while I still own my units?

Yes. An OP’s taxable sale of contributed property may allocate built-in gain to you. Annual income and changes in your share of debt can also affect taxes. A tax protection agreement, if offered, has its own scope and limits. [4] [5]

Can I redeem the units after one year?

There is no universal promise. Your documents determine holding periods, restrictions, notice, pricing, and settlement choices. Even if units can become shares, non-traded shares may remain difficult to sell. Review both stages of access to your money. [5] [6]

Does a 721 plan replace the DST’s 1031 deadlines?

No. If you first use a deferred 1031 exchange to acquire a DST interest, that exchange has its own deadlines and rules. The later contribution is a separate step. Confirm whether it is required, optional for you, or controlled by another party. [7] [8]

Who should review the proposed transaction?

Your CPA should review basis, debt, allocations, and tax costs. Your attorney should review title, contracts, rights, and estate effects. Your investment professional should help assess the receiving investment and alternatives. These reviews answer different questions; one does not replace the others.
