Tax Planning

What is a 1031 exchange, and how can a dentist use one?

Ian McGinnis, Founder & Financial PlannerPublished 3 min read

Short answer: a 1031 exchange (from IRC Section 1031) lets you sell investment or business real estate and defer the capital-gains tax by reinvesting the proceeds into “like-kind” real estate. It’s one of the most powerful tax-deferral tools in real estate — but it runs on strict deadlines (45 and 180 days) and precise rules, so it must be set up correctly before you sell.

How does a 1031 exchange work?

When you sell appreciated investment real estate, you’d normally owe capital-gains tax (plus depreciation recapture). A 1031 exchange lets you roll the entire proceeds into a new “like-kind” property and defer that tax. “Like-kind” is broad for real estate — you can exchange, say, a rental building for raw land, an apartment, or a fractional interest — as long as both are real property held for investment or business use. Your personal residence doesn’t qualify.

What are the 1031 deadlines?

  1. 1Day 0 — you sell (relinquish) your property; the proceeds go to a qualified intermediary, not to you.
  2. 2Within 45 days — you must formally identify potential replacement property in writing.
  3. 3Within 180 days — you must close on the replacement property.
  4. 4To fully defer — reinvest all the proceeds and replace the debt; any cash or debt relief you keep (“boot”) is taxable.

What are the requirements and pitfalls?

  • Qualified intermediary — a third party must hold the proceeds; you cannot receive them.
  • Like-kind real property held for investment or business — not a primary home or property held to flip.
  • Equal or greater value and debt — to fully defer, don’t “trade down” or pocket cash.
  • Same taxpayer — the entity that sold generally must be the one that buys.
  • The clock is unforgiving — 45 and 180 days include weekends and holidays.

What if you can’t find a replacement in time?

This is where passive vehicles help. A Delaware Statutory Trust (DST) is pre-packaged institutional real estate whose fractional interests qualify as like-kind replacement property — useful when the 45-day clock is running and you can’t close on a whole building in time. A 721/UPREIT structure can extend the strategy further.

Does a 1031 ever eliminate the tax?

Not by itself — it defers. But investors often “swap till they drop”: exchanging repeatedly to keep deferring, then passing the property to heirs, who may receive a step-up in basis at death that effectively erases the deferred gain. Whether that fits your estate plan is a question for your CPA and estate attorney.
