Reference/Frequently Asked Questions
Tax-strategy questions, answered plainly.
The most common questions we receive about 1031 exchanges, 721 UPREIT contributions, California clawback rules, DST structures, and how 721 Hub operates.
What's the difference between a 1031 exchange and a 721 UPREIT contribution?
A 1031 exchange under Section 1031 of the Internal Revenue Code allows you to defer capital gains taxes by rolling the proceeds from a sold property into a like-kind replacement property within strict deadlines (45-day identification window, 180-day close). A 721 UPREIT contribution under Section 721 allows you to contribute real property to an Operating Partnership in exchange for OP units, also deferring gain recognition at the time of contribution. The key differences: a 1031 exchange requires you to acquire another direct property interest, while a 721 contribution results in OP unit ownership that is economically equivalent to REIT shares. The 721 path removes management responsibilities entirely but subjects you to the REIT's liquidity and redemption timeline. Many investors use a 1031 into a DST as a bridge, then execute a 721 drop-and-swap into the sponsor's UPREIT at the end of the DST hold period.
Why does 721 Hub focus on the West Coast first?
California accounts for a disproportionate share of 1031 exchange volume in the United States, driven by decades of appreciation in multifamily, industrial, and commercial property. The state's unique tax complexity -- the clawback mechanism under Revenue and Taxation Code Section 18032, Mello-Roos obligations, high county-recorder fees, and the absence of a state-level no-exchange-period extension -- creates a decision tree that is materially different from Arizona, Texas, or Florida. West Coast investors also face concentrated equity gains from tech-adjacent commercial markets, particularly in the Bay Area. We cover these markets in depth first because the tax stakes and exchange complexity are highest there.
What's a clawback, and how does California's apply to my 1031?
California's clawback (Revenue and Taxation Code Section 18032) requires a California resident who completes a 1031 exchange into out-of-state replacement property to pay California tax on the deferred gain when that out-of-state property is ultimately sold in a taxable transaction. The clawback does not trigger at the time of the 1031 exchange itself -- only at final disposition. This matters because many California investors use their 1031 to reposition into Texas or Florida properties to avoid future state income tax on appreciation. California tracks these transactions and will assert tax on the original deferred gain when it receives notice of the final sale. Careful structuring -- including evaluation of whether a subsequent 1031 into California property would reset the clock -- is essential. Consult a California-licensed CPA before structuring any exchange involving out-of-state replacement property.
Can I roll a DST into another DST or a 721 UPREIT?
You can roll a DST interest into another DST via a 1031 exchange, provided you satisfy the standard exchange requirements. The DST interest you are selling must have been held for investment or productive use, and the replacement DST must qualify as like-kind. A DST interest is treated as a direct interest in real property for 1031 purposes under Rev. Rul. 2004-86. The 721 path (DST to UPREIT) requires that the DST sponsor offer a 721 exchange option at wind-down -- this is specific to certain DST structures built with that exit in mind. Not all DSTs have a 721 pathway. Confirm the exit structure with the sponsor before selecting a DST if UPREIT conversion is part of your long-term plan.
Why use a Qualified Intermediary instead of holding the proceeds yourself?
Section 1031 and Treasury Regulations Section 1.1031(b)-2 require that the exchanger not receive, pledge, borrow against, or otherwise have constructive receipt of the exchange proceeds at any point during the exchange period. If you hold the proceeds -- even briefly -- the IRS will likely treat the entire transaction as a taxable sale. A Qualified Intermediary (QI) holds the proceeds in a segregated escrow account, acquires the replacement property on your behalf, and transfers it to you at closing. The QI structure is not optional; it is a prerequisite for a valid deferred exchange. Choosing a QI with adequate errors-and-omissions insurance and bonding is a material due diligence step, since QI failures (fraud, insolvency) have cost exchangers their deferred gain.
What does swap-til-you-drop actually mean for my heirs?
Swap-til-you-drop is the strategy of continuously deferring capital gains through successive 1031 exchanges until death. At death, your heirs receive a stepped-up cost basis under Section 1014 of the Internal Revenue Code -- the basis resets to the fair market value of the property at the date of death. The result: all deferred capital gains that accumulated over years or decades of 1031 exchanges are permanently extinguished. Your heirs inherit the property at current market value with no embedded tax liability. The strategy requires that the property remain inside a 1031 structure (not converted to personal use) and that you do not trigger a taxable recognition event before death. Changes to the step-up basis rules have been debated in Congress repeatedly; the current rules under Section 1014 remain in effect as of the date of this publication.
Are tax-strategy articles a substitute for talking to a CPA?
No. 721 Hub articles are educational frameworks that explain how tax rules work in general terms. They cite IRC sections, Treasury Regulations, and IRS rulings to give you the structural vocabulary before you sit down with a tax professional. They do not account for your specific basis history, prior exchange transactions, passive activity loss carryforwards, state-specific complications beyond what is explicitly noted, or the full complexity of your individual return. Do not make any tax or investment decision based solely on editorial content published here. A licensed CPA with 1031 and real estate tax experience is the correct professional to analyze your specific exchange.
Is 721 Hub a broker-dealer or registered investment adviser?
No. 721 Hub is an independent publication. We publish tax-strategy and geographic market analysis. We do not sell securities, offer investment advice, or provide brokerage services. Consult your own CPA, tax attorney, and licensed advisor before any investment, tax, or legal decision.
Do you cover commercial markets outside the U.S.?
No. Section 1031 is a provision of the U.S. Internal Revenue Code and applies only to U.S. real property exchanged for U.S. real property. Foreign real property is explicitly excluded from like-kind exchange treatment under Section 1031(h). Our geographic coverage is limited to U.S. markets where 1031 exchange activity, state tax complexity, and DST/UPREIT availability are most relevant to our readers.
What happens if my market isn't on the list?
Our initial market coverage focuses on 12 high-volume 1031 exchange markets across the West Coast, Southwest, Texas, Mountain West, and key Eastern metros. If your primary market is not yet covered, the strategy library and tax-analysis articles apply across all U.S. markets -- the 1031 mechanics, clawback considerations, and UPREIT structuring questions are not market-specific. You can send a market coverage request to tips@721hub.com. We are actively expanding coverage based on exchange volume and reader demand.
What are the downsides of a 721 UPREIT exchange?
The main downsides of a 721 UPREIT exchange are irreversibility, the end of future 1031 flexibility, and a tax bill that is deferred rather than eliminated. Once you contribute property for operating-partnership (OP) units, you generally cannot execute a 1031 exchange back into direct real estate, and converting OP units into REIT shares is a taxable event. Investors also give up direct control of the underlying real estate: the REIT sponsor manages the portfolio, sets distribution policy, and controls the redemption timeline. Liquidity is tied to the REIT's redemption program rather than a sale you initiate. These trade-offs are why the 721 path suits investors prioritizing passivity and diversification over control and continued tax deferral.
What are the tax implications when you sell or convert your OP units?
Contributing property for OP units defers your capital gain, but that deferral ends when you sell the units or convert them into REIT shares -- either is a taxable event that recognizes the previously deferred gain, even though a conversion may generate no cash. Because the OP units take a carryover basis from the contributed property, the embedded gain travels with them until a recognition event occurs. One exception is holding the units until death: under Section 1014 of the Internal Revenue Code, heirs generally receive a stepped-up basis, which can extinguish the deferred gain. Model the eventual conversion or sale with a CPA before contributing, because the timing of recognition is the crux of the 721 decision.
Can you reverse a 721 UPREIT exchange once it is done?
No. A 721 UPREIT contribution is generally a one-way door. Once real property becomes OP units, you cannot execute a tax-deferred 1031 exchange back into direct real estate -- exiting means selling the units or converting them to REIT shares, both taxable events that recognize the deferred gain. This is the single most important structural difference from a 1031 exchange, where you can keep rolling gains into new properties indefinitely. Confirm you are comfortable with a permanent move out of direct ownership before contributing, and review the sponsor's redemption terms so you understand how and when you can access liquidity.
Does a 721 exchange have the same 45-day and 180-day deadlines as a 1031?
No. The 45-day identification and 180-day closing deadlines are Section 1031 requirements and do not apply to a 721 contribution itself -- a 721 UPREIT contribution has no statutory identification window or exchange-period clock. In practice, many investors first complete a 1031 exchange into a DST built with a 721 exit (which does carry the 45/180-day deadlines), then convert to OP units later when the sponsor offers the UPREIT option. So the deadlines can still matter to the overall sequence, just not to the 721 step. Confirm the exit structure with the sponsor before selecting a DST if a later 721 conversion is part of your plan.
