DSTs and the 1031 Same-Taxpayer Rule: LLCs, Trusts, and Co-Owners

By Jerry Baker

In a 1031 exchange, the taxpayer selling the old property generally must be the taxpayer buying the replacement, including a qualifying DST interest. The names on the forms can differ when an LLC or trust has the same federal tax owner. Ask your CPA, attorney, and qualified intermediary to confirm the owner and signer before closing.

Why ownership deserves an early review

Property selection gets most of the attention in an exchange. The owner listed on the new subscription can seem like a small detail. It is not small if it changes who acquires the replacement.

Section 1031 applies to an exchange of qualifying business or investment real estate. It does not give one person a general right to defer gain by having someone else buy an investment with the sale proceeds. [1]

People call this the “same-taxpayer rule.” The phrase is useful. But it does not just mean “copy the name and tax ID into every box.” The legal owner and the owner for tax can differ. The forms must reflect both roles correctly.

I would rather settle those questions before you reserve an investment. A deadline is an awkward time to discover that the new LLC is taxed differently from the old one.

Distinguish the owner, the taxpayer, and the signer

RoleQuestionExample
Legal ownerWho holds the property or interest under the documents?An individual, LLC, or trustee in a stated capacity
Federal tax ownerWho is treated as owning the asset for income tax?The owner of a disregarded LLC
Authorized signerWho has power to sign for the legal owner?An LLC manager or trustee

One person can occupy more than one role. But the roles are still distinct. A manager signing for an LLC does not buy the investment personally just by signing the document.

Ask for the full title and capacity on each agreement. “Alex Lee” and “Alex Lee, as trustee” may describe different legal roles. The tax review then determines who is treated as owning the assets behind that title.

A family relationship or common mailing address does not resolve these questions. Neither does using the same bank for both transactions. Follow the ownership facts and documents.

Why a qualifying DST can serve as replacement property

Revenue Ruling 2004-86 describes a DST with a key tax feature. Its owners are treated as owning their share of the real estate beneath the trust. With those facts, the DST interest can qualify for an exchange. The other Section 1031 rules still apply. [2]

The investor acquires a beneficial interest rather than a deed to a separate apartment or warehouse. The federal tax treatment is why that particular structure can work. It does not mean every interest labeled “trust” is qualifying real estate.

The offering's tax structure is one question. Your ownership of the interest is another. An otherwise qualifying DST does not solve a problem caused by the wrong taxpayer subscribing for it.

Have the tax team review the offering and the proposed buyer together. The analysis should connect the property being sold, the exchange documents, and the owner that will hold the new interest.

A single-member LLC may be disregarded

A U.S. LLC with one owner is usually not treated as separate from that owner for federal income tax. This is called a disregarded entity. It can elect to be taxed as a corporation instead. Without that election, its activity appears on its owner's return. It still exists as an LLC under state law. [3]

Suppose Morgan owns all of an LLC that holds a rental property. The LLC has not elected corporate treatment. If it sells, the federal tax review generally looks through that LLC to Morgan.

Morgan may buy the replacement directly. Another valid disregarded LLC owned only by Morgan may also work. In each case, the same person remains the tax owner. The team must still check the forms, and the sponsor must accept that buyer.

Do not stop at counting members. Review any tax elections, ownership changes, and prior filings. An LLC with one member that is taxed as a corporation is not the same as a disregarded LLC.

The owner need not be a person. It could be a partnership or corporation. The IRS generally treats a disregarded LLC's activity as part of that owner. Trace that chain. Do not assume the person who manages the LLC is its tax owner. [3]

An EIN is not a stand-alone test

A disregarded LLC can have its own employer identification number, or EIN. That alone does not make it a separate owner for federal income tax. The rules for payroll tax and some excise taxes treat the LLC differently. [3]

For income-tax information reporting, the IRS generally directs a disregarded single-member LLC to use its owner's Social Security number or EIN. Its own EIN may still exist for payroll, banking, or other needs.

Form W-9 has rules for both the owner's name and the disregarded entity's name. The owner's tax class also matters. An LLC taxed as a partnership or corporation follows different rules. Complete the form based on the facts. Do not change entries just to make the numbers match. [4]

If two forms show different numbers, ask why. It might be an error, or it might reflect different reporting duties. If two forms show the same number, that alone does not prove that legal and tax ownership are correct.

A living trust needs a tax-owner check too

A revocable living trust is often a grantor trust while its creator keeps certain powers. With a grantor trust, the relevant income and deductions generally belong to its tax owner. The owner might be treated as owning all of the trust or just part. [5]

If you are treated as owner of the relevant trust assets before and after the exchange, using that trust may preserve continuity. The lawyer should confirm the trust terms and the CPA should confirm the federal tax treatment.

Do not use “revocable” and “irrevocable” as complete tax answers. An irrevocable trust can have grantor-trust features. A trust can also be only partly a grantor trust. The relevant assets and owner must be identified.

A trust name may remain the same while its tax treatment changes, such as after a death. A change of trustee may affect signing authority without necessarily changing the tax owner. Each event deserves its own review.

The Form 1041 instructions describe different reporting methods for grantor trusts. A trust's separate tax number or a particular form title is therefore not enough to settle the ownership question. [5]

A partnership's property is not each partner's property

When a partnership sells real estate, the usual exchange is at the partnership level. The fact that its tax results flow through to partners does not mean each partner sold a direct share of the building.

A U.S. LLC with two or more members is usually taxed as a partnership. Other rules or an election can change that result. The members being related does not by itself make it disregarded. Nor does having no employees. [3]

If the partnership is the exchanging owner, it can consider acquiring a qualifying DST interest. A disregarded subsidiary owned by that same partnership may also be part of a structure reviewed by counsel. The individual partners are not automatically the replacement buyers.

A sale of a partnership interest differs from a sale of the partnership's land or building. In general, the interest is not Section 1031 replacement property. The IRS describes a narrow exception for a valid Section 761(a) election. Have counsel review it before relying on it. [6]

Ask whether your proposed transaction is an asset sale, an interest sale, a distribution, or a combination. The everyday phrase “selling my share” is too vague to decide the tax result.

When partners want different outcomes

One partner may want cash. Another may want a DST. A third may want a building to manage. Those goals are understandable, but a common wish to split the money does not create three separate exchanges.

Have counsel review the entity documents, tax basis, liabilities, sale stage, and proposed transfers well before closing. Partnership distributions and changes in debt shares can carry their own tax effects. [7]

A “drop and swap” moves property interests out of an entity before the owners sell or exchange them. It is not just a form that erases the past. Counsel must review who owned the property and why it was held. The sale plan and any related parties also matter.

No universal number of days makes a last-minute distribution safe. Nor does waiting until after the replacement closes automatically make a planned ownership change harmless. The legal and tax analysis must address the actual plan and sequence.

Sometimes the best available route will differ from what one partner hoped to do. Identify that conflict before relying on a particular DST allocation or a closing date.

Direct co-owners can present a different case

Two people may own direct interests in the same rental property without owning a partnership interest. IRS guidance distinguishes mere co-ownership of rental property from arrangements that amount to a business partnership. The actual activity matters. [7]

Suppose two unrelated individuals each own a direct 50% interest and counsel confirms they are not a partnership for tax purposes. Each person's sale and replacement plan can then be reviewed for that person's share.

One may choose a taxable sale while the other pursues an exchange. That is different from assuming partners in an LLC can divide the entity's sale proceeds and obtain the same result.

The percentage, closing statements, QI arrangements, and replacements should reflect the actual owners. Do not assume an equal split of a bank transfer proves equal property ownership. Use the deeds, agreements, and tax history.

If the co-owners provide services or operate under a joint business plan, ask whether that activity changes the federal classification. A tenancy-in-common label alone should not end the review.

Marriage does not remove the ownership questions

For a married couple, begin with the source and character of the old property's ownership. It might be separate property, community property, joint ownership, or property held by an entity or trust.

Filing a joint income-tax return does not mean every asset can be retitled freely during an exchange. The tax preparer and attorney need to identify the owners and their shares under the applicable rules.

A special IRS rule applies to some entities owned only by spouses as community property. A qualifying entity may be disregarded or taxed as a partnership, based on how it is reported. A change between those treatments counts as an entity conversion. [3]

The rule has conditions. The entity must be wholly owned as community property, no other person can be a federal tax owner, and it cannot be treated as a corporation. Do not assume every married couple's two-member LLC meets them.

Review prior returns as well as current wishes. An estate-planning change may be useful, but it should be coordinated with the exchange instead of added to the subscription at the last minute.

Adding another owner needs more than a name change

You may want a spouse, child, or business partner to own part of the new investment. That can change the taxpayer or the share acquired by the exchanging owner. It may also involve a gift, sale, contribution, or new entity.

Separate the goals. First determine what replacement interest the exchanging taxpayer must acquire. Then review any proposed co-investment or transfer, its funding, and its timing. Do not assume that adding another person's name to the entire interest is harmless.

Some purchases can involve distinct owners bringing separate funds for separate interests. Whether a specific arrangement works depends on what each person acquires and the full transaction. It should not be treated as a blanket exception or a universal prohibition.

Tell the tax team about any plan to transfer ownership soon after closing. The investment-purpose requirement applies to the property acquired. A prearranged transfer can raise questions that a completed subscription alone does not answer. [1]

Build an ownership file before the property sells

Start with the recorded title and the document showing how the current owner acquired the property. Add the current entity or trust documents and amendments. Include a clear list of owners and their shares.

Provide the CPA with prior tax returns that show how the property and entity have been reported. Include any classification elections and their effective dates. An online formation certificate does not show the whole tax history.

Ask counsel to identify the people who can sign and whether consent from others is required. If a power of attorney will be used, confirm that the parties will accept it for this transaction.

Keep a short written summary of the conclusions: legal seller, federal tax owner, proposed replacement holder, tax reporting details, and signer. The purpose is to keep everyone working from the same facts, not to create a do-it-yourself tax opinion.

Check the whole ownership timeline

An ownership chart shows a point in time. An exchange needs a history as well. Ask the team to list when the old owner acquired the property, when any tax election took effect, and when members joined or left. Add the sale contract date, sale closing, and planned replacement closing.

Consider an LLC that began with one owner and later admitted a second member. Its original formation file does not tell you its tax status at the sale. A return from before that change may not answer the question either. The CPA needs the dates and the facts behind the change.

Use that timeline to spot gaps in the file. If the deed, tax return, and operating agreement seem to tell different stories, ask why before funds move. Keep the answer with the records. The goal is to describe what happened, not to choose whichever date or document gives the easiest answer.

Translate the confirmed ownership into the subscription

Before signing, compare the subscription's purchaser name with the approved ownership summary. Check the trust date, entity name, state of formation, ownership share, and signer capacity where relevant.

Then compare the QI agreement, assignment documents, identification, and closing instructions. A correct subscription does not fix an exchange agreement prepared for the wrong party. A correct QI agreement does not fix a purchase made by someone else.

The deferred-exchange rules cover what the taxpayer gives up and receives. They also set deadlines and rules for naming the replacement property. Having the same tax owner matters. It does not resolve every other exchange rule. [8]

Confirm that the sponsor has accepted the purchaser and received any required entity or trust documents. Do not assume a signed form guarantees acceptance or that an allocation is held indefinitely.

I can help coordinate the offering paperwork around the structure your advisers confirm. The tax and legal conclusions should come from the professionals reviewing your facts.

Pause new ownership changes while the exchange is underway

An ownership change does not pause the exchange clock. In a standard deferred exchange, the identification period is generally 45 days. The completion period ends at the earlier of 180 days or the applicable tax return due date, including extensions. [8]

Before adding a member, making a tax election, changing a trust, or distributing property, contact the tax and legal team. Explain what has already closed and what remains pending. Dates can matter as much as the final ownership chart.

If a death, divorce, merger, or other major event occurs, obtain advice on that specific event. Do not apply an ordinary titling checklist as though it resolves special succession or transfer rules.

Also check practical timing. The sponsor may need new documents or approvals. A bank may need updated signing authority. Build those tasks into the closing plan rather than assuming all parties can make changes on the last day.

What to do if the paperwork looks wrong

Raise the issue as soon as you see it. Send the relevant documents to the CPA, attorney, QI, and sponsor contact. Describe the difference plainly: wrong owner, wrong capacity, wrong tax number, or an unexplained mismatch.

A spelling error and a real change in tax ownership are not the same problem. Counsel should determine what happened and what can be corrected. Do not assume the exchange has failed, but do not assume a replacement form cures everything either.

Keep the original records and a dated correction history. Do not backdate documents or alter a signed form to make the file appear consistent. If funding has not occurred, ask the responsible parties how to handle the pending closing while the issue is reviewed.

After closing, retain the final ownership summary with Form 8824, basis records, and the offering's annual tax packets. The next preparer should be able to follow the transaction without guessing why the names differ.

Frequently asked questions

Must every name and tax ID match exactly?

The documents must be accurate, but a simple name or number comparison is not the whole tax test. Disregarded entities and grantor trusts can create valid differences. Have the advisers trace the actual federal tax owner and correct the reporting.

Can I buy a DST through my single-member LLC?

It may work if the LLC is disregarded to the same tax owner that gave up the old property. Confirm elections, ownership, the offering's acceptance rules, and the documents before purchase. A corporate-taxed LLC is different. [3]

Does an LLC's own EIN mean it is a separate tax owner?

No. A disregarded LLC can have its own EIN for certain purposes. Income-tax reporting generally uses the owner's tax identification information under IRS rules. Confirm why each number is being used.

Can my revocable trust hold the replacement?

Often it can when the same person remains the tax owner of the relevant assets. The trust terms, grantor status, and signing authority need review. A trust's name alone does not establish its treatment.

Can partners each exchange their share of an LLC's sale proceeds?

Not simply because income passes through to them. Identify whether the LLC is a partnership and whether it, rather than the members, sold the property. Any plan to divide property or ownership requires separate advance review.

Does filing jointly let spouses use either name?

No blanket rule permits that. Separate property, community property, direct ownership, and entity ownership can produce different facts. Review the old and new ownership with advisers familiar with the applicable state rules.

Who should confirm the final DST owner?

The CPA and attorney should confirm tax treatment and legal title, while the QI coordinates the exchange documents. The sponsor checks its purchaser requirements. Keep their conclusions aligned before signing and funding.
