721 Exchange FAQ: OP Units, Taxes, Deadlines, and Exits

By Jerry Baker

A 721 exchange generally contributes property to a partnership for units without recognizing gain at that point, subject to exceptions. For real estate owners, that partnership may be part of an UPREIT connected to a REIT. These questions explain what changes, what can create tax, and what to check before you trade a building for units.

I want you to understand the trade before focusing on the tax benefit. You may gain professional management and exposure to a different portfolio. You also give up direct control and accept the partnership's rules for income, transfers, and exits. Whether that is a good trade depends on the actual terms and your needs.

Keep value, equity, and basis separate

Three numbers appear throughout these answers. Property value is what the parties agree the real estate is worth. Equity is value after debt and relevant deal adjustments. Tax basis is the amount tracked under tax rules to calculate gain, loss, and other items. They are not interchangeable.

Suppose a property is worth $2 million, has $600,000 of debt, and has a $700,000 adjusted tax basis. Before costs or other adjustments, the property has $1.4 million of equity and $1.3 million of built-in gain. If the agreed OP-unit value is $25, that equity would translate to 56,000 units.

The unit count does not determine tax basis. Assume the debt analysis properly assigns the investor $400,000 of partnership liabilities after contribution. In a simple contribution with no other adjustments, outside basis would start at $700,000. Subtract $600,000 of debt relief and add $400,000 of allocated debt. The result is $500,000. The net $200,000 deemed money does not exceed the $700,000 starting basis in this example. [1] [2] [3]

That is an illustration, not an approval of a transaction. Debt allocations must follow the law. Cash payments, disguised-sale rules, special unit rights, and other facts can change the result. Bring your actual numbers to your CPA rather than copying the example into an agreement.

Frequently asked questions about 721 exchanges

What does Section 721 actually do?

Section 721 generally allows property to be contributed to a partnership for a partnership interest without recognizing gain or loss at that time. It applies to more than real estate and is not limited to UPREITs. This guide focuses on the real estate use: an owner contributes property to a REIT's operating partnership for OP units. The rule has exceptions, including certain transfers to investment companies. A transaction labeled a contribution can still contain a sale or another taxable element. The written label does not replace a review of what each party actually gives and receives. [4] [5]

What is an UPREIT?

In an UPREIT, a REIT holds real estate through an operating partnership. The REIT holds an interest in that partnership, and contributing property owners may hold OP units alongside it. That creates a way to accept property without requiring every contributor to take REIT shares directly. The operating partnership agreement sets the unit holder's economic and other rights. Ask for the ownership chart and identify the entity receiving your property. A presentation that uses “the REIT” for every entity can hide important differences in ownership, debt, and contractual obligations.

Are OP units the same as REIT shares?

No. OP units are partnership interests. REIT shares are interests in the REIT itself. They may have related economic terms, but they are not the same legal or tax asset. Your unit class may have its own rules for payments, votes, transfers, and exits. Do not assume a one-for-one relationship or identical rights without reading the documents. A unit's possible future exchange for shares also does not make it a share today. Ask which entity sends payments and tax reports. Which entity must honor a permitted request to redeem units?

How is a 721 contribution different from a 1031 exchange?

A 1031 exchanges qualifying real estate for like-kind real estate. A 721 contribution receives a partnership interest. Ordinary OP units do not qualify as Section 1031 real property, even if the partnership owns buildings. The real-property rules have a narrow exception for some partnerships with a valid Section 761(a) election. Do not assume an ordinary UPREIT meets it. This difference affects your next exit decision. A 721 can qualify under its own rules. The units need not qualify as Section 1031 replacement property. [4] [6]

Can I sell my property first and then use 721 to defer that sale?

Not by simply contributing the cash afterward. The property sale has its own tax result. Putting the sale cash into a partnership later does not erase that gain. For the direct real estate strategy described here, the plan is to contribute the property. Talk with your tax and legal advisers before signing a sale arrangement that could close off that path. If you already sold, show them the closing records and any exchange documents. Other rules may matter, but calling the next investment a 721 is not a repair for an earlier taxable sale. [5]

Does every kind of property qualify?

Section 721 is a broad property-contribution rule. It does not contain the same investment-use and dealer-property restrictions as Section 1031. That does not mean every property is suitable for an UPREIT or that every transfer avoids tax. The partnership must want the asset, and counsel must check the transaction's tax treatment, liabilities, and other rules. A personal-use property raises practical and tax questions that differ from a leased commercial asset. Do not import 1031 requirements into 721 as though they were the same statute, or treat the absence of that restriction as approval. [4]

Can a small property owner use this approach?

Possibly, but there is no universal minimum property value in Section 721. Direct-contribution programs can set their own size, property-type, location, and financial requirements. A building may be legally transferable yet too small or otherwise unsuitable for a particular operating partnership. Ask about acceptance criteria early, before ordering expensive reports. Some owners consider a qualifying DST investment with a possible later contribution, but that is a different sequence with separate risks and rules. A later UPREIT deal is not assured. The sponsor may be unable or unwilling to complete it.

Can I 1031 into a DST and later receive OP units?

That can be possible under a properly structured plan. Revenue Ruling 2004-86 supports real-property treatment for the DST described in it. The other exchange rules still must be met. The initial exchange must stand on its own; the later contribution must qualify separately. Ordinary REIT shares or OP units cannot simply replace the DST in that first step. Read whether a later contribution is required, permitted, or only contemplated, and ask counsel to review the entire sequence. An attractive second step cannot cure an invalid first exchange. [7] [6]

Who decides whether a DST converts into OP units?

The governing documents decide. A sponsor might hold a purchase or contribution option. Investors might receive an election, or the plan may have limited investor choice. “Optional 721 exit” is incomplete unless you know whose option it is. Ask what votes or consents are required. How is value set? What happens if you object? What choices remain if the receiving partnership declines? Keep the written answer with the offering documents. A salesperson's expectation is not the same as an enforceable right to choose a different exit.

Are there 45-day and 180-day deadlines for a direct 721?

Those are deferred 1031 exchange deadlines, not a general timetable imposed by Section 721. A direct contribution follows the agreed transaction schedule and any other applicable rules. If you start with a 1031 exchange into a DST, identify within 45 days. Complete by the earlier of 180 days or the return due date, including extensions. The periods overlap. Work to earlier practical dates for document review and wires. A direct contribution can also face tight lender or contract deadlines even though the 1031 clock does not govern it. [4] [8]

Is a two-year wait required before every contribution?

No universal two-year waiting period makes every 721 transaction valid. Two-year presumptions appear in the disguised-sale regulations for related property and money transfers. Transfers within two years generally raise a sale presumption. Transfers more than two years apart generally receive the opposite presumption. Facts and exceptions can change either result. That is not a blanket DST holding-period safe harbor. Counsel must also review any earlier 1031 exchange, intent, planned steps, and binding agreements. Waiting a set number of days cannot replace that analysis. [9]

Can I receive some cash and some units?

A transaction can be structured with both, but the cash is not automatically tax deferred. Depending on the facts, the arrangement can include a partial sale, a distribution, or a disguised sale. Ask for separate calculations of the cash, liabilities, contributed portion, unit basis, and recognized gain. Also confirm whether receiving cash changes your pricing or unit rights. A partial taxable transaction may still meet your goals, but it should be a conscious choice with a tax reserve. “Part cash, part units” describes the payment; it does not establish the tax result. [5] [9]

What happens to my old tax basis?

Section 722 generally carries the old property basis into your basis in the partnership interest. The rule also requires certain adjustments. Debt shifts also affect outside basis. That is different from the fair value used to issue units. Later income, losses, distributions, and other items can change basis again under Section 705. Keep a basis schedule from the contribution forward. Do not replace that schedule with the account's market value. The capital account on a K-1 may also differ from outside basis. Those numbers serve different purposes. [1] [10]

Can debt create tax even if I receive no cash?

Yes. A net reduction in your share of liabilities can be treated as money distributed under Section 752. Money distributed beyond your adjusted outside basis can create gain under Section 731. Liability treatment under the disguised-sale rules requires a separate review as well. For example, assume a $300,000 net deemed distribution and $250,000 of basis. With no other adjustments, the simple distribution rule can create $50,000 of gain. Actual debt allocations cannot be chosen merely to make the calculation work. Have the CPA review the loan facts and allocation method. [2] [3]

Will I owe tax while I still own the units?

You can. Partnership income is generally allocated to partners, and tax can be due even if that income is not paid out. The partnership may also sell an asset or take another action that creates gain. Section 704(c) addresses built-in gain and loss tied to contributed property. Holding your units therefore does not ensure that all gain stays deferred until you redeem them. Ask about expected tax distributions, reporting dates, and the manager's plans for the property you contributed. Keep cash reserves for your own estimated payments. [11] [12]

Does a nonrecourse loan remove the investment risk?

No. The loan terms may protect your personal assets. The lender can still have a claim against the property. Debt payments and loan maturities still matter. Consider an asset worth $10 million with $5 million of debt. If value falls to $8 million while debt stays fixed, equity falls from $5 million to $3 million. The property lost 20% of its value; the equity lost 40%, before costs. That simple example shows why debt matters even without a personal guarantee. Review the loan documents and any exceptions to limited liability with counsel.

Does a tax-protection agreement guarantee no tax?

No. It is a contract with specific promises, conditions, limits, and remedies. It may address a property sale, debt maintenance, or compensation for certain tax costs. Check how long it lasts and which actions it covers. Read the exceptions. What happens if the party that owes you money cannot pay? Ask your attorney to explain the remedy in a concrete example. A promise to reimburse a defined tax cost is different from preventing the taxable event. The agreement should be reviewed with the partnership documents and your tax calculation.

Are distributions guaranteed or equal to the quoted yield?

No. A stated distribution rate may be a target, a recent rate, or a calculation using a particular unit value. Confirm which one. Payments depend on assets, income, expenses, debt, reserves, and the unit terms. They may change. Also ask whether distributions include borrowed money or a return of capital rather than operating cash. A distribution rate is not total return: you can receive payments and still lose money if unit value falls. Match your spending plan to a range of possible payments rather than a single advertised percentage.

How are my property and the OP units valued?

They are two sides of the pricing decision. A generous property value may not help if the units received are overpriced. Ask how the property was valued and request the appraisal if one exists. Check the unit value date, fees, and closing adjustments. Ask how the receiving portfolio was valued. For a nontraded REIT, an estimated value is not a quoted market price you can necessarily realize. SEC staff guidance highlights valuation disclosures and the limits of estimated share values. Review both values before focusing on the number of units. [13]

When can I redeem units or convert them to shares?

Read the agreement for your exact unit class. There may be a waiting period, notice requirements, limits, and exceptions. The partnership or REIT may choose how to settle a permitted request. You might receive cash or shares. Do not assume every program provides a one-year exit or automatic conversion. Ask for the steps from request to completed payment and identify who can delay them. A right that becomes available on a certain date is not the same as cash arriving that day. Plan important spending without relying on an uncertain redemption.

Does a public REIT mean I will have liquid shares?

Not necessarily. A publicly registered nontraded REIT can file reports without having shares listed on a stock exchange. Its repurchase plan may have limits or be suspended. Exchange-listed shares generally have a market, but your units must first become transferable shares under the applicable terms and securities rules. Private REITs have another set of disclosure and liquidity features. Confirm which category applies today. A proposed listing or future liquidity event is a business plan, not an existing market for your investment. [14]

What tax can arise when I sell or redeem units?

The result depends on the transaction. Selling a partnership interest generally recognizes gain or loss under Section 741. Section 751 requires ordinary-income treatment for certain items. That can include certain recapture items. A redemption treated as a partnership distribution follows distribution rules. Exchanging units for REIT shares is generally a taxable disposition. Do not apply one capital-gain rate to the whole account value. Have the CPA calculate proceeds, debt relief, adjusted basis, gain character, and state consequences before the request becomes binding. [15] [16] [3]

Can I redeem only part of my investment?

Some agreements permit partial requests, subject to minimums and other limits. That may help match cash needs over time, but the tax result still needs a calculation for the units involved. Changes in basis, allocated debt, values, and ordinary-income items can affect the amount recognized. Ask about request size, frequency, proration, and the form of payment. A partial-redemption plan is useful only if the contract allows it and the investment has capacity to honor requests. It should not be presented as a guaranteed way to spread taxes evenly over several years.

Can I exchange the units back into a building under 1031?

Ordinary OP units are partnership interests and generally cannot be used in a Section 1031 exchange for real estate. That is why the move deserves careful thought when future 1031 flexibility matters. It does not mean every possible partnership property distribution is always taxable; partnership distributions have their own complex rules. But a tax-free return to the property you contributed should not be assumed or promised. A sale or redemption followed by a building purchase can leave you investing after-tax proceeds. [6] [3]

What happens if I die while holding OP units?

Inherited basis may change under Section 1014, subject to exceptions. For inherited units, the outside-basis calculation generally starts with fair market value. It adds the successor's share of partnership debt. It subtracts applicable income-in-respect-of-a-decedent amounts, a special category of income the decedent had not yet reported. The partnership's asset basis does not automatically rise in the same way. Section 743 and a Section 754 election may be relevant. Do not assume every deferred tax disappears. Have the estate attorney and CPA review the ownership, beneficiary plan, unit transfer rules, and outside- and inside-basis treatment together. [17] [18] [19]

Do I have to be an accredited investor?

It depends on the offering and securities exemption. Many private programs are limited to accredited investors, and a Rule 506(c) offering requires reasonable verification of that status. Other offering rules differ. Ask which exemption is being used and which standards apply to your purchase. Passing that test does not show that the investment fits. You still need to assess your needs, risk capacity, and time horizon. It also does not mean the SEC has approved the offering. Eligibility, tax qualification, and investment suitability are separate questions. [20]

Which costs should I compare?

Ask about property closing costs, transfer costs, acquisition charges, ongoing management fees, fund expenses, performance compensation, and exit costs. Determine who pays each charge and whether it affects the units issued or later returns. Compare projections after the same categories of expense. If one illustration includes costs and another omits them, the difference is not meaningful. A recurring 0.75% charge on a $2 million base is $15,000 per year. The amount changes if the base changes. That may be only one layer of expense. [21]

What should I bring to a first meeting, and who reviews what?

Bring ownership records, debt terms, tax-basis records, recent property income and expenses, your income target, and expected cash needs. Include any sale contract or exchange paperwork already in place. I can help evaluate the available investment and explain its tradeoffs. Your CPA reviews tax calculations and reporting; your attorney reviews rights, agreements, and structure. Ask the sponsor for written answers on valuation, unit terms, and the business plan. The decision should remain understandable after everyone leaves the meeting. You should know what you own next, how you might exit, and which risks you have accepted.
