721 Exchanges and Inherited Basis: What Heirs Need to Know

By Jerry Baker

Heirs who inherit operating partnership units after a 721 exchange may receive a tax-basis adjustment, often called a step-up. It may reduce future taxable gain without erasing every tax item inside the partnership. A sound plan checks the heir's unit basis, the partnership's property basis, and the records needed to connect them.

Why the owner's low basis matters

A qualifying Section 721 contribution can defer gain when an owner transfers property for a partnership interest. It generally does not give the property a fresh tax basis just because the parties agree on a higher value. Nonrecognition means the tax is not recognized at that step; it does not mean the tax history disappears. [1]

The operating partnership, or OP, owns the real estate. The investor owns units in that partnership. Tax rules track both the property and the owner's interest. Contributions, income, losses, cash distributions, and debt can affect those records over time. [2]

This is why I would not describe a 721 exchange as a way to wipe the tax slate clean. It changes the ownership structure. An inherited-basis adjustment is a later rule with its own requirements. The plan needs to work during the owner's life, even if the hoped-for estate result never occurs.

The inherited-property rule can adjust basis up or down

Section 1014 generally uses fair market value at death for qualifying property acquired from a decedent. Other valuation rules and exceptions can apply. If value is below the old basis, the adjustment may be a step-down. The common term “step-up” describes only one direction. [3]

For a simple illustration, assume a debt-free inherited asset qualifies for this rule and has no special exceptions. If the prior basis was $300,000 and the required valuation is $900,000, the new basis is $900,000. If the prior basis was $1 million and the required value is $900,000, the basis instead falls.

That rule is not unique to UPREIT units. It can also apply to real estate inherited directly. An owner should compare the investments on control, risk, cash flow, and family needs rather than assume only a 721 route offers this potential tax treatment.

The right question is which asset passes at death and which rule sets its basis. The answer may differ for units, shares, a trust asset, or a right to receive income.

Keep outside basis and inside basis separate

Outside basis is the investor's tax basis in the partnership interest. Inside basis is the partnership's tax basis in its assets. A change in one does not automatically change the other by the same amount.

For inherited partnership interests, Treasury Regulation 1.742-1 generally starts with the interest's fair market value at the applicable date. It adds the successor's share of partnership liabilities and reduces the amount for value attributable to income in respect of a decedent. That is more involved than copying the account value onto a tax return. [4]

The buildings may still have low tax basis on the partnership's records. A later building sale could produce partnership gain even though the heir recently received a higher basis in the units. Special adjustment rules help address this mismatch when their requirements are met.

I find it helpful to label the two records by owner: “basis of my units” and “basis of partnership assets.” The labels are plain, but the distinction prevents a major planning error.

The contributed property's tax history needs review

When an owner contributes appreciated property, Section 704(c) rules generally keep its built-in gain from being shifted to other partners. The rules also address transfers of a contributing partner's interest. A successor can inherit the relevant allocation history. [5]

That does not mean heirs necessarily pay all of the original gain. It means the CPA must coordinate that history with the heir's basis and any special inside-basis adjustment. Skipping either side can produce a misleading estimate.

Ask the partnership tax team for the contributed-property schedules and any remaining built-in gain records. The tax capital account on a K-1 is not a substitute for a full outside-basis schedule. One box on a form cannot answer every basis question.

If the investment has gone through mergers, property sales, or new contributions, retain those records as well. The tax history may follow more than one asset or tier of partnerships. An account statement rarely explains that path.

What a Section 743(b) adjustment does

Section 743 provides for certain adjustments to partnership property after an interest transfers by sale, exchange, or death. A Section 754 election is a common route. The statute also requires adjustments in certain substantial built-in loss cases. An election is not always the only route. [6]

The adjustment is for the successor partner. It does not reset the common basis of every building for every investor. It can be positive or negative, based on the difference between the successor's outside basis and the relevant share of inside basis.

Treasury Regulation 1.743-1 explains the calculations and how special basis is tracked. It uses partnership capital, liabilities, and other tax facts. A simple ownership percentage times the portfolio's total basis may not produce the right result. [7]

For an owner considering a program, a useful question is: “How does the partnership handle a holder's death and a successor's basis adjustment?” The answer should come from the tax documents and responsible team, not a general statement that heirs receive a step-up.

A worked example with inherited units and debt

Here is a simplified, fictional example. Nora inherits OP units with a fair market equity value of $1 million. Her allocated share of partnership liabilities is $400,000. Assume no value is attributable to income in respect of a decedent, and assume the general inherited-basis rules apply.

Her initial outside basis is $1.4 million: the $1 million interest value plus the $400,000 liability share. The extra $400,000 is a tax-basis component. It is not cash Nora receives and does not mean the units are worth $1.4 million in her account.

Next, assume the partnership's tax team determines that her relevant share of inside basis is $600,000. With the required Section 754 election in effect, the simplified positive Section 743(b) adjustment is $800,000: $1.4 million minus $600,000.

Illustrative itemAmountWhat it means
Inherited interest value$1,000,000Equity value of the units
Allocated partnership liabilities$400,000Debt included in this basis calculation
Initial outside basis$1,400,000Basis in Nora's interest
Relevant share of inside basis$600,000Assumed tax-team calculation
Special positive adjustment$800,000Adjustment for Nora, allocated under tax rules

This table illustrates the two levels. It is not a tax worksheet for a real estate portfolio. Actual debt allocations, valuation, prior tax history, and asset-by-asset calculations can change the result. [4] [7]

Who makes the election, and who provides notice?

The partnership makes a Section 754 election. It must follow the filing rules. Generally, it files the election with a timely partnership return, including extensions, for the relevant year. A valid election already in effect can continue to apply. An heir does not make that partnership election merely by choosing a basis on a personal return. [8]

The family should promptly notify the partnership of the death and ask for its tax-information checklist. Regulation 1.743-1 includes a written notice requirement within one year of death for the described transfer where an election is in effect. The required notice includes identifying and valuation information. Do not treat that outer rule as a reason to wait. [7]

The estate's return deadlines or a proposed sale may require work much sooner. Assign someone to gather the records, someone to confirm delivery, and someone to follow up on the partnership's calculation.

Keep proof of what was supplied. If a valuation changes, the tax team needs the revised facts. A missing adjustment can be hard to diagnose years later when the heir no longer has the original correspondence.

The special adjustment must be assigned to assets

An $800,000 adjustment is not automatically an $800,000 current deduction. Section 755 rules allocate the adjustment among partnership assets and different types of income property. The assets receiving the adjustment affect how and when it matters. [9]

An adjustment linked to land will not work like one linked to a depreciable building. An adjustment may affect later gain or depreciation, depending on the asset and tax rules. An heir cannot simply divide the whole amount by a chosen number of years and deduct the result.

Request a schedule that connects the total adjustment to its asset allocations. Then ask the CPA to check how it appears in the partnership's annual reporting. The schedule should explain changes after sales or other transactions.

In a large portfolio, this may be detailed work. Complex tax work does not alone make an investment a poor fit. But the family needs to know what that work involves. It should have skilled help before it relies on a hoped-for tax benefit.

Basis keeps changing after the inheritance

The date-of-death calculation is a starting point. Later income, losses, distributions, and liability changes can alter outside basis. Special inside-basis adjustments may also be used over time. A future sale needs the basis on that future date, not an unchanged number from the estate appraisal.

Schedule K-1 instructions explain that the partner must maintain basis information and that taxable partnership income can differ from cash distributions. A distribution should not be labeled tax-free simply because the interest was inherited. [10]

Return to Nora's example. If all relevant facts stayed unchanged, a hypothetical sale for $1 million cash with $400,000 of debt relief would have $1.4 million of amount realized. Against $1.4 million of outside basis, the simplified overall gain is zero. This excludes costs and special character rules.

If the cash price instead rose to $1.08 million under those same simplifying assumptions, the overall gain would be $80,000. Real transactions require intervening basis changes and any ordinary-income portion to be checked. The phrase “sold soon after death” is not a complete tax calculation. [2]

Use a supported valuation for the right interest

The asset being valued is the actual inherited interest, with its rights and limits. A property appraisal, a REIT share price, and the value of restricted OP units are not automatically interchangeable. The estate adviser should decide which valuation evidence is appropriate.

IRS Publication 551 explains the general inherited-basis rules and exceptions. A valid alternate valuation election can change the relevant valuation date. It is not a free choice to use whichever later price produces the best income-tax answer. [11]

Retain the valuation date, unit count, class, supporting method, and information about restrictions. If someone proposes a discount, ask for its legal and factual basis. Do not assume every private interest qualifies for a standard percentage reduction.

A family should also avoid mixing values from different dates in one calculation. Using a death-date unit value with a much later debt allocation may give a neat-looking figure that is wrong. The tax team needs records that line up.

Lifetime gifts and trust ownership need separate review

A lifetime gift generally follows gift-basis rules rather than the inherited-property rule. For appreciated property, carryover basis is often central; loss situations and other adjustments can differ. Moving units to a child before death does not automatically give the child a current-value basis. [11]

Trust labels can also mislead. Revenue Ruling 2023-2 describes an irrevocable grantor trust whose asset was transferred by completed gift and was outside the owner's gross estate. Under those facts, the owner's death did not create a Section 1014 basis adjustment. Grantor-trust income-tax treatment alone was not enough. [12]

That ruling does not say every trust fails to qualify. Counsel must review the actual powers, ownership, inclusion rules, and method by which property passes. A trust created for one goal may have a different income-tax effect from a revocable living trust.

Before retitling units, coordinate estate, gift, income-tax, and transfer-restriction issues. A change meant to simplify ownership can have effects that are difficult to reverse.

Separate remaining income tax from estate tax

Section 1014 excludes rights to income in respect of a decedent from its general basis adjustment. Future partnership income also remains subject to the applicable tax rules. These are reasons to avoid promising heirs that every payment will be tax-free. [3]

Estate tax is a different tax on transfers at death. Whether an estate owes it depends on the whole estate and applicable rules, not just the unit basis. Form 706 filing, payment, and election questions should be reviewed separately from the heir's eventual sale. [13]

For property subject to the consistent-basis rules, the tax basis must align with the required estate valuation. Treasury rules also recognize later lawful basis adjustments, including partnership adjustments. Keep the estate records and the heir's tax records connected. [14]

The goal is one supported set of facts used for the right purpose on each return. It is not to use a low value for one tax and an unrelated high value for another.

Give the family a record they can use

Before a transfer, ask the owner to keep a list of what went into the partnership. Include the old property basis, the value used at closing, the debt, and the number of units received. Keep later tax schedules with that file. The people who inherit should not have to rebuild decades of records from bank deposits.

After a death, start a new page for the new owner. Note the date, the unit count, the value, and who prepared the value. Then add the tax team's figures for debt and basis. Mark any estimate as an estimate until the adviser has enough facts to finish the work.

Here are five questions the family can take to the CPA:

Ask for the answer to the last question before signing an exit request. A form that looks routine can start a tax event. It helps to give the CPA the actual form, the agreement, and the proposed date, rather than describe the transaction from memory.

If two heirs receive different shares of an interest, keep a record for each. If one heir sells while another holds, their later basis schedules will no longer move together. The family can share a filing system without assuming that every person's tax result is the same.

This work is easier when the estate lawyer, CPA, and partnership tax team know who is responsible for each task. Agree on the next date to check progress. A missing document is more likely to be found when one person has a clear job and a date to report back.

A tax benefit does not decide the investment question

Inherited-basis planning does not remove property risk, debt risk, fees, or loss of control. Nor does it create a right to sell. Non-traded REIT shares can have limited liquidity, and OP units have their own contractual restrictions. [15]

An owner should ask whether the investment works for current income, likely holding time, health needs, and family cash reserves. A possible tax benefit at death is not a reason to accept a portfolio the owner cannot comfortably hold.

Also consider future flexibility. Ordinary OP units and REIT shares are not direct Section 1031 replacement real property. A higher inherited basis does not change that rule. [16]

My job is to help explain the investment choices and tradeoffs. The CPA and estate lawyer determine the family's tax treatment. Before moving ahead, I would want both conversations to use the same ownership structure and current documents.

Frequently asked questions

Do inherited OP units receive a step-up in basis?

They may receive an inherited-basis adjustment under the applicable rules. The calculation considers value, partnership liabilities, and certain income items. It can be a step-down if value has fallen. Confirm the result for the actual owner and interest. [4]

Does that erase all the deferred gain inside the partnership?

Not automatically. The heir's outside basis and the partnership's inside basis are separate. Contributed-property allocations and a possible Section 743(b) adjustment must be coordinated. A statement that all gain simply vanishes skips that important work.

Can I make the Section 754 election myself?

The partnership makes the election through its tax filing. Ask whether one is already in effect and what the tax team requires after a death. The estate and heir still need to provide timely, accurate information and review the resulting basis schedules. [8]

Is a special basis adjustment an immediate deduction?

No. It must be allocated among assets under the tax rules. Its use depends on the assets and later events, such as depreciation or a sale. It is not cash, and it does not automatically reduce the current year's taxable income by the full amount. [9]

Can heirs sell right after death without tax?

A supported basis adjustment may reduce gain, but a sale still needs a calculation. Debt relief, costs, post-death changes, and special income rules matter. The investment must also permit the transaction. No-tax treatment and immediate liquidity are separate questions.

Does putting units in a trust guarantee a step-up?

No. The trust's terms and the tax rules determine the result. A grantor trust can be outside the owner's gross estate and fail to receive the adjustment under the facts in Revenue Ruling 2023-2. Have estate counsel review the actual structure. [12]

Is this basis benefit available only through a 721 exchange?

No. Other qualifying inherited assets, including directly held real estate, can receive inherited-basis treatment. A 721 exchange should be evaluated for its full investment and ownership effects. It should not be presented as the only path to a possible basis adjustment for heirs.
