Delaware Statutory Trust 1031 Exchange Rules: The Seven Powers Your Trustee Cannot Have.
Rev. Rul. 2004-86 lets a beneficial interest in a Delaware statutory trust stand in for the rental you sold, which is how an investor defers a $925,000 gain without screening another tenant. The treatment survives only if the trustee is stripped of seven specific powers.

An investor sells the fourplex she has owned since 2003, wires the proceeds to a qualified intermediary, and starts the 45-day clock with no intention of ever replacing another water heater. She wants the deferral without the tenants. The Delaware statutory trust 1031 exchange rules are what make that possible, and they hang on a list of things the trust's own trustee is forbidden to do. Let the trustee hold one of those powers and every investor in the deal owns a partnership interest instead of real property, so the exchange never happened.
Why an interest in a trust counts as real property.
Pool a dozen investors into a Delaware entity that owns an apartment building and you almost always have a business entity under the check-the-box regulations, which means a partnership. Since the Tax Cuts and Jobs Act, §1031 reaches only real property, and a partnership interest is not real property. Exchange into one and you have a taxable sale with a Form 8824 stapled to it.
Rev. Rul. 2004-86 puts a DST on the other side of that line by classifying it as an investment trust under Treas. Reg. §301.7701-4(c). An investment trust is respected as a trust rather than a business entity when it has a single class of ownership interest and no power to vary the investment of its holders. Strip the trustee down to collecting rent and distributing it, and the trust is a grantor trust as to each beneficiary, so each one is treated as owning an undivided interest in the building itself. The trust is transparent because it is powerless.
The Delaware statutory trust 1031 exchange rules the trustee has to live under.
The ruling describes a trust agreement in which the trustee has no power to do seven things. Practitioners call them the seven deadly sins. This isn't a list of best practices: each item is a power that would let the trustee vary the investment, which turns every beneficiary's interest into a partnership interest. The trustee cannot:
- Sell the property and buy replacement property with the proceeds.
- Accept additional capital contributions once the offering closes, from existing investors or new ones.
- Renegotiate the existing loan or borrow new funds, except where a tenant bankruptcy or insolvency has caused or threatens a default.
- Renegotiate the existing leases or enter into new ones, subject to the same tenant bankruptcy or insolvency exception.
- Make more than minor, non-structural modifications to the property unless the law requires them.
- Hold cash between distributions in anything other than short-term obligations maturing before the next distribution date.
- Reinvest the proceeds from a sale of the property.
Two of these shape how every offering gets built. The leasing prohibition is why most DSTs sit under a master lease: the trust leases the whole property to a sponsor affiliate, and the master tenant signs the tenant leases so the trustee never does. The financing prohibition is why DST debt is fixed-rate and sized to mature well past the projected hold, since it is a loan nobody in the trust is allowed to touch.
The IRS has bent the list once, and only briefly. Rev. Proc. 2020-34, issued June 4, 2020, let a DST accept certain loan forbearances, lease modifications for tenants in COVID-19 hardship, and additional cash contributions, limited to actions requested or agreed to between March 27, 2020 and December 31, 2020. Relief here arrives narrow, dated, and expired.
The 45 days do not get longer because the replacement is a trust.
Nothing about a DST buys you time. The 45-day identification and 180-day closing deadlines run from the day the relinquished property closes. What a DST buys is closing speed: subscribing is a securities subscription rather than a purchase and sale, with no lender, no appraisal, and no inspection period, so it can fund in days. That makes it the standard third slot on a three-property identification list, and the only practical way to place an odd $137,000 of leftover proceeds no whole building will absorb.
Debt is the other reason people land here. Replace $600,000 of mortgage with nothing and the relief is treated as money received under Treas. Reg. §1.1031(b)-1(c), so gain gets recognized under §1031(b) whether or not you touched cash. DST offerings carry non-recourse debt at the trust level and allocate a share to each beneficiary, so a retired investor who no longer shows the income a lender wants can replace that $600,000 without qualifying for a loan. That often solves a timing problem more cheaply than a reverse exchange.

Tax year 2026, a married Utah couple filing jointly, property depreciated straight-line so the entire $255,000 is unrecaptured §1250 gain. Assumes taxable income above the $613,700 top of the 15% capital gain bracket for 2026 under Rev. Proc. 2025-32 and above the $250,000 §1411 threshold. Utah's flat rate is 4.45% for 2026 under S.B. 60, signed March 23, 2026 and retroactive to January 1. Deferral is not forgiveness: the $925,000 rides into the DST interest as carryover basis.
What you hand over along with the money.
You give up control and liquidity, both absolutely. No vote, no redemption right, no exit before the sponsor sells, which is usually five to ten years out and is the sponsor's call. The offering load sits inside the price per interest rather than on an invoice, so read the use-of-proceeds table and see how much of your $1,100,000 buys real estate. My verdict: the deferral is real, and it isn't a reason to own something you wouldn't buy on its own numbers.
Then find the springing LLC provision, because nearly every offering has one. If the property is heading toward default and the trust needs a power the seven prohibitions withhold, it converts into an LLC so someone can renegotiate. That saves the asset and costs you the tax treatment: the converted entity is a partnership, your interest is a partnership interest, and §1031 doesn't reach it. Your exit becomes a taxable sale in a year you didn't pick.
The pleasant version of that door is the UPREIT exit. Many sponsors plan to contribute the property to a REIT's operating partnership under §721 and hand investors OP units, which defers gain on the contribution. It is also the last like-kind exchange those dollars will ever see, because OP units and the REIT shares they convert into are not real property. Fine if you plan to hold until death for the §1014 step-up, expensive if you meant to keep exchanging.
No K-1 arrives, and the depreciation schedule is yours to build.
Because the DST is a grantor trust, the sponsor sends a grantor trust letter rather than a Schedule K-1, and your share of rents, interest, and operating expenses goes on Schedule E as though you owned the building outright. Depreciation isn't on that letter and cannot be, because it depends on the basis you carried in and the sponsor has no idea what that was. Under Treas. Reg. §1.168(i)-6 the exchanged basis keeps running over the relinquished property's remaining recovery period, and any additional cash you invested depreciates on its own new schedule. Skip that and you pay tax on income you already sheltered.
