1031 Exchange for Orthopedic Surgeons: Deferring Tax on Real Estate Sales

An orthopedic surgeon who owns a medical office building and sells it alongside the practice faces a layered federal tax bill: 20% long-term capital gains rate, 3.8% Net Investment Income Tax, and up to 25% on accumulated depreciation recapture — on top of whatever state taxes apply. A properly executed 1031 like-kind exchange defers all of that by rolling the proceeds into a qualifying replacement property.

Section 1031 of the Internal Revenue Code has not been eliminated — the One Big Beautiful Bill Act (OBBBA, July 2025) left it completely intact — and it remains one of the most powerful tax deferral tools available to orthopedic surgeons who own investment real estate. The mechanics are strict: wrong timing, wrong intermediary, or wrong property type disqualifies the exchange and triggers the full tax bill immediately.

What you're actually deferring: the tax math

Before deciding whether a 1031 exchange is worth structuring, quantify what you're deferring. For an orthopedic surgeon selling a medical office building at a $1.5M gain after 10 years of ownership:

State taxes are additional. A California surgeon deferring a $1.5M gain avoids 13.3% state capital gains tax — another $200,000. A 1031 exchange in a high-tax state can defer over 50 cents per dollar of gain. That deferred capital compounds inside the replacement property rather than being paid to the IRS.

The gain is not eliminated — it is deferred until you sell the replacement property (and can be deferred again with another exchange). If you die holding the replacement property, your heirs receive a stepped-up cost basis and the deferred gain disappears entirely under § 1014.⁴

What qualifies: like-kind property after TCJA

The Tax Cuts and Jobs Act (2017) narrowed the definition of qualifying exchange property to real property only. Before TCJA, equipment, art, aircraft, and other personal property could be exchanged. Today, only U.S. real property held for investment or business use qualifies — and the "like-kind" definition for real property is broad: a single-family rental can be exchanged for an apartment building, raw land for a commercial warehouse, or a medical office building for a fractional interest in a Delaware Statutory Trust (DST) that owns institutional real estate.

What qualifies:

• Medical office building held in a practice real estate LLC
• Investment rental property (residential or commercial)
• Raw land held for investment
• Commercial warehouse, retail building, multifamily property
• DST fractional interests that satisfy IRS Rev. Rul. 2004-86

What does not qualify:

• Your primary residence (separate exclusion rules under § 121 apply)
• ASC membership interests (LLC membership = personal property, ineligible since TCJA)
• Medical equipment, practice furniture, or instruments
• Foreign real property exchanged for U.S. real property
• Property held primarily for sale, not investment (dealer property)

The timeline: two hard deadlines

The IRS allows no exceptions to these deadlines — not for illness, travel, or market conditions:

Day 0: Closing on the sale of the relinquished property. Proceeds go directly to a Qualified Intermediary (QI); you cannot touch them or the exchange is immediately disqualified ("constructive receipt").

Day 45: You must identify potential replacement properties in writing to the QI by midnight. You may identify up to three properties of any value (the "3-property rule"), or more if specific value rules are met. The identification list is binding — you can only acquire properties from this list.

Day 180: You must close on the replacement property. The 180-day window is measured from the sale closing, not from the 45-day identification deadline. If your tax return is due before Day 180, the exchange must close before the return due date or by filing an extension.

Boot: when partial exchanges trigger partial taxes

To defer 100% of the gain, you must: (1) reinvest all net proceeds from the sale into the replacement property, and (2) acquire replacement property with equal or greater debt. If you receive cash or reduce your debt load, that amount is "boot" — taxable in the year of exchange at capital gains rates.

Orthopedic surgeons commonly encounter boot when selling a fully-depreciated MOB and buying a lower-value replacement property. If you sold for $2M and only need $1.5M in replacement property, the $500K difference is boot, taxed at 23.8% federal plus state. You can either pay the tax on the boot and defer the rest, or identify replacement properties worth at least $2M to eliminate boot entirely.

Delaware Statutory Trusts: the passive replacement option

Identifying replacement property within 45 days is one of the most operationally stressful aspects of a 1031 exchange. For a surgeon selling a building during a practice transition — when you're simultaneously closing the practice sale, negotiating employment terms, and managing the move — actively acquiring a new property on a 45-day clock is often impractical.

A Delaware Statutory Trust (DST) solves this. A DST is a fractional ownership interest in institutional real estate — commonly medical office buildings, multifamily, industrial, or commercial — managed by a sponsor. Under IRS Revenue Ruling 2004-86, DST beneficial interests qualify as like-kind replacement property for 1031 purposes.⁵

DSTs allow you to:

• Close into a ready-made replacement property without active deal management
• Split proceeds across multiple DSTs to diversify while meeting the exchange rules
• Transition from active landlord to passive income recipient — relevant if you're selling your MOB as part of a practice exit
• Receive monthly cash distributions from institutional-quality real estate at a fraction of direct ownership cost

DST investments are illiquid (typically 5–10 year hold periods), carry sponsor and property risk, and are accredited-investor-only offerings. They are not appropriate as a growth vehicle — their role in a 1031 exchange is preserving deferred gain while generating passive income during retirement or a practice deceleration phase.

OBBBA interaction: bonus depreciation on replacement property

The OBBBA permanently restored 100% bonus depreciation for qualifying property placed in service after January 19, 2025. This creates a meaningful opportunity when acquiring replacement property in a 1031 exchange — but with an important limitation: bonus depreciation applies only to the new basis in the replacement property, not to the carryover basis from the exchanged property.⁶

Example: You sell an MOB with $0 remaining basis (fully depreciated) and acquire a $2.5M replacement property, using $1.5M of exchange proceeds and $1M of new financing. The $1.5M carryover basis cannot be bonus depreciated (it represents deferred gain from the original property). The $1M of new investment (the additional debt) represents a new basis position eligible for bonus depreciation via cost segregation. A cost segregation study on the replacement property can identify the portion of that new basis that qualifies for immediate expensing.

1031 vs. QOZ vs. installment sale: which is right?

When 1031 does not make sense

You plan to hold until death. If your estate plan is to hold real estate, convert it into passive income, and pass it to heirs with a § 1014 step-up, a 1031 exchange may be unnecessary complexity — you get the gain elimination at death either way. For a 65-year-old surgeon with a small gain, the exchange overhead may not justify the deferral benefit.

You have capital loss carryforwards from investment accounts. Large carryforward losses can offset real estate gain directly, reducing or eliminating the tax you're trying to defer. Run the tax math against your actual loss carryforward balance before structuring an exchange.

The replacement property doesn't pencil out as an investment. The purpose of a 1031 exchange is tax deferral — not justification for a bad real estate investment. Acquiring an overpriced replacement property solely to avoid tax is a worse outcome than paying the tax and redeploying capital efficiently. The gain deferral has value, but it does not add returns to a bad deal.

The timeline doesn't work. If you can't identify a qualifying replacement property within 45 days — realistic in thin markets or during a complex practice transition — you may be setting up a failed exchange that triggers the full tax bill plus interest. Sometimes a clean sale is cleaner.

Checklist: before you close on the sale

1. Engage a Qualified Intermediary — before closing, not after. The QI must be in place before you sign the settlement statement.
2. Confirm property type — verify that the relinquished property is real property held for investment or business use (not primary residence, not personal property).
3. Identify replacement property candidates — you have 45 days from closing. DST sponsors can provide same-day identification documents when active deal flow is thin. Have alternatives ready.
4. Calculate your boot exposure — if there's any chance the replacement property value will be lower than sale proceeds, model the boot tax now so you can decide whether to accept it or find additional replacement property.
5. Coordinate with your CPA on § 1250 recapture — depreciation schedules from the relinquished property determine the recapture amount and its carryover to the replacement property's basis.
6. File Form 8824 — the like-kind exchange is reported on your tax return in the year of the exchange. Your CPA needs all QI documentation before tax filing.
