The short answer
When the trust sells its property, the sponsor closes the sale without an investor vote, the trust terminates, and your share of the net proceeds is either wired to a qualified intermediary under an exchange agreement signed before closing or paid to you as taxable cash. Your 45-day identification period and 180-day exchange period run from the trust's closing date because you own an undivided interest in the real estate, not from the day funds reach you. From there you can exchange into other DSTs or direct property, take some cash as boot, or accept a sponsor's 721 option if one exists.

|---|---|
| Clock start | The closing date, when your relinquished property is transferred (Reg. §1.1031(k)-1(b)(2)) |
| Exchange period | Earlier of 180 days or the return due date including extensions |
| QI requirement | Written exchange agreement before closing; no right to receive or borrow the money |
| Tax on a cash-out | Unrecaptured §1250 gain at up to 25%, rest at 0/15/20%, plus 3.8% NIIT over thresholds |
| Partial reinvestment | Recognized gain = smaller of realized gain or boot received (Form 8824) |
| Sponsor 721 windows | Hines: 12 months from year two; JLL: any time after two years; Ares: units or cash |
The sponsor sells without your vote and the trust ends at closing, so the decision you control is where your share goes
DST agreements follow Rev. Rul. 2004-86, in which the trust terminates on disposition of the property, and one PPM states that beneficial owners have no right to approve or disapprove of the sale. Sponsors generally market a property when its projected hold of five to ten years is reached or a loan maturity approaches, but the projected hold is not a promise and neither is the timing.
What you control is the instruction you give before closing: your share of net proceeds goes to a qualified intermediary under an exchange agreement, or it comes to you. Once cash is paid to you, or you hold the right to receive it, the exchange is over for that money.
Your 45 and 180 days run from the trust's closing date, not from the day your share arrives
Under Reg. §1.1031(k)-1(b)(2) the identification period ends at midnight on the 45th day after the date the taxpayer transfers the relinquished property, and the exchange period on the earlier of the 180th day or the due date of your return including extensions. Your relinquished property is your undivided interest in the building, which the ruling treats as ownership of the real estate itself, so the transfer date is the trust's closing.
Sale proceeds often reach the intermediary days after closing while the lender payoff and closing statements settle, and a sale that closes in the last 180 days of a year ends your exchange period at the return due date unless you extend; both traps are set out at advanced 1031 deadline traps. If a portfolio trust sells two properties on different dates and you treat them as one exchange, the regulation measures both periods from the earliest transfer, so ask your CPA whether to run them as separate exchanges.
A $300,000 share of proceeds: what cash-out, full exchange and partial reinvestment each cost in federal tax
Hypothetical: your adjusted basis in the interest, carried from the property you exchanged years ago, is $100,000; the trust's sale returns $300,000 of net equity to you, and $80,000 of depreciation has accumulated across the chain. Cashing out realizes $200,000 of gain: $80,000 of unrecaptured §1250 gain taxed at up to 25% ($20,000), $120,000 at the 15% or 20% rate ($18,000 at 15%), and 3.8% net investment income tax on the $200,000 if your income is over the $200,000 single or $250,000 joint threshold ($7,600), about $45,600 before state tax.
A full exchange through your intermediary defers all of it, but only if the replacement matches the value you gave up, including your share of the loan the trust paid off. If the trust was 50% leveraged, your $300,000 of equity stood behind roughly $600,000 of value, so the replacement needs about $600,000 of value with at least $300,000 of debt or added cash, the arithmetic at balancing value, equity and debt.
Reinvest $200,000 and keep $100,000, and Form 8824 sets recognized gain at the smaller of realized gain ($200,000) or boot received ($100,000), so $100,000 is taxed and $100,000 stays deferred. How the 25% and 15% rates split that recognized $100,000 is your CPA's computation; the planning side is at intentional boot.
Three exits at closing: cash, a new exchange into DSTs or direct property, or a sponsor 721 option if the trust was built with one
The exchange path repeats the rules you used the first time: up to three replacements of any value or any number within 200% of what you sold, each identified in writing by a distinguishable name, which for a DST is the trust's name and the interest you will buy. Sponsors often have a next offering ready, and naming a DST as a backup identification is described at using DSTs as backup properties.
Some trusts carry a fair-market-value purchase option instead: Hines Global Income Trust's 10-K gives its operating partnership a 12-month window starting two years after each DST closing to buy the interests for OP units; JLL Income Property Trust's S-11 allows exercise any time after two years for units or cash; Ares Industrial REIT's 10-K offers an OP-unit election, a cash election, or both with at least 15% of the consideration available in cash. The option belongs to the sponsor, and taking units ends future 1031 exchanges for that money, as explained at after a 721 UPREIT, can you 1031 again.
Prepare 90 days ahead: intermediary engaged, replacements screened, records in order, so day 45 is not spent opening accounts
The regulation requires a written exchange agreement with an intermediary that is not a disqualified person and that limits your right to receive, pledge, borrow or otherwise obtain the benefits of the money before the exchange period ends. Sign it before the trust's closing and give the sponsor the intermediary's wiring instructions, since a wire to you first cannot be undone; what to look for in an intermediary is at qualified intermediary requirements.
- Read the trust's quarterly reports for sale language and ask the sponsor for its expected closing window and the estimated net proceeds per $100,000 invested.
- Confirm your adjusted basis and accumulated depreciation from your records and the trust's annual tax reporting, covered at how DST income is taxed and reported.
- Pre-screen replacement offerings so identification can be signed the week of closing, using the eight-number checklist at how to read a DST PPM.
- Decide in advance how much boot you want and whether a cash-out DST fits the debt replacement, described at cash-out DST explained.
- If closing falls after early July, tell your CPA the return may need an extension to preserve the full 180 days.
- File Form 8824 with the return for the year of the trust's closing, even if the replacement closes the following year.

Related questions
Will the sponsor wire my share straight to my intermediary?
Yes, if the exchange agreement is signed and the wiring instructions are delivered before closing; sponsors ask each investor for an election because proceeds sent to you cannot be exchanged afterward.
Do I need a new intermediary and a new exchange even though I used one to buy the DST?
Yes. The earlier exchange closed when you bought the interest; the trust's sale is a new transfer of relinquished property, with its own agreement, its own 45 and 180 days and its own Form 8824.
If I hold three DSTs and one sells, is that a partial exchange?
No. Each trust's sale is a separate relinquished property, so you exchange only that share and the other two continue untouched.
Is the buyer sometimes the sponsor's own REIT?
It can be, through the FMV option described above; a sale to a third party ends the master lease and can trigger a termination payment to the trust, while an option exercise turns you into a unitholder. The PPM's conflicts section tells you which is permitted.
What paperwork proves my sale for the return?
Your share of the closing statement, the trust's final tax reporting and Form 8824 for the year of closing; keep the identification notice and exchange agreement with them, following what to do after your 1031 exchange closes.
