DST 1031 Replacement Property

Using a DST beneficial interest as replacement property does not remove any part of the standard 1031 mechanics. The relinquished property still closes through a qualified intermediary, the 45-day identification clock and the 180-day closing clock still run from the date that closing, and the exchanger still has to identify specific replacement property in writing within that window. What changes is what gets identified and funded: instead of a single parcel with one closing date set by negotiation, the exchanger is buying into an offering with its own subscription deadline, minimum investment, and closing schedule set by the sponsor, not by the exchanger.

That difference matters because a DST offering can sell out, close early, or have its available allocation reduced between the day it looks attractive and the day exchange funds are actually ready to move. Treating a DST as a fallback identified alongside direct property, rather than the only option identified, is a common way experienced exchangers manage that timing exposure.

Replacement property must be identified in writing to the qualified intermediary within 45 days of the relinquished property's closing, under the identification rules in 26 CFR 1.1031(k)-1. A DST interest is identified by the legal description of the trust's real property and the exchanger's intended percentage or dollar interest in it, the same way a fractional tenancy-in-common interest would be identified. Because DST offerings can close to new investors on their own schedule, exchangers frequently identify one or more DSTs alongside a directly sourced property under the three-property or 200 percent identification rules, so a closed offering does not strand the exchange.

Waiting until late in the 45-day window to start reviewing DST offerings compresses due diligence into days rather than weeks. The offering documents, sponsor history, and property-level debt terms take real time to work through, and that review should start as soon as the relinquished property is under contract, not after it closes.

Exchange proceeds held by the qualified intermediary are wired directly to the DST sponsor or its escrow agent at closing, in the same way funds would move to a title company for a direct purchase. The exchanger never takes constructive receipt of the cash at any point, which is the core requirement that preserves tax deferral. Sponsors set a minimum investment for each offering, commonly in the range of a hundred thousand dollars, though the figure varies by offering and should be confirmed in the current subscription documents rather than assumed from a prior deal.

Because the minimum is fixed per offering, an exchanger with proceeds that do not divide evenly across DST minimums may need to combine a DST allocation with a smaller direct property, a different DST, or accept some taxable boot on the leftover amount. Working through the arithmetic with the qualified intermediary and the DST sponsor's back office before the closing date avoids a last-minute funding shortfall.

Nothing in Section 1031 requires a single replacement property, and DST proceeds are commonly split across two or more offerings to diversify property type, geography, or sponsor exposure. Each DST allocation is identified and funded separately, and each has its own PPM, debt terms, and distribution schedule. Splitting proceeds this way trades simplicity for diversification, and it increases the amount of offering-document review required, since each trust's restrictions and fee structure need to be checked independently rather than assumed to match a prior offering from the same sponsor.

Exchangers who split across multiple DSTs also take on multiple K-1s or trust reporting statements at tax time, which a tax preparer should be told about in advance so depreciation and income are tracked correctly across each interest.

To defer all recognized gain, the total value acquired in replacement property, DST interests included, generally needs to equal or exceed the net sale price of the relinquished property, and the equity reinvested needs to equal or exceed the equity taken out. A DST's built-in mortgage debt at the trust level counts toward satisfying the debt-replacement side of that test in proportion to the investor's beneficial interest, which is why the leverage ratio of a specific offering is a diligence item and not a side note; too little debt in the replacement DST relative to debt paid off on the relinquished property can leave boot exposed to tax.

Basis in the DST interest carries over from the relinquished property under the standard 1031 basis rules, adjusted for any boot recognized, and that carryover basis is what determines depreciation going forward. IRS Publication 544 and the Form 8824 instructions cover how gain, basis, and boot are calculated and reported for the exchange.

The 180-day closing deadline is fixed by the relinquished property's sale date and is not extended because a DST offering sells out or delays its closing. A sponsor's own subscription timeline, lender approval process, or offering size limits can move independently of the exchanger's deadline, which is why identifying a single DST as the only replacement property carries real risk if that offering closes to new capital before day 180.

Confirming current offering availability directly with the sponsor close to the identification deadline, rather than relying on marketing material that may already be stale, is a basic step that protects the exchange. An exchanger working against a tight closing window should have a funded backup identified, whether that is a second DST, a direct property, or an installment structure, before the 45-day identification period closes rather than after.
