An owner of appreciated commercial or investment real estate faces two separate tax questions that get resolved differently depending on when the property changes hands: capital gains tax, which applies to a sale during the owner's lifetime, and estate tax, which applies to the value of the estate at death above the current exemption threshold. Real estate held until death receives a step-up in basis to fair market value, which can erase the capital gains liability entirely for heirs, but that benefit only applies at death, not to any lifetime sale or exchange along the way.
The Step-Up in Basis and Why It Matters
When a property passes to heirs through an estate, its cost basis generally resets to fair market value as of the date of death, which means decades of accumulated appreciation and depreciation recapture can disappear for capital gains purposes if the heirs sell shortly after inheriting. This is why many long-term real estate owners plan around holding appreciated property until death rather than selling it during their lifetime, particularly when the embedded gain is large. The step-up applies to the value in the estate, though, so it does not eliminate exposure to federal or state estate tax if the estate's total value exceeds the applicable exemption.
Where Estate Tax Exposure Comes From
Federal estate tax applies above a per-person exemption that has moved substantially over the past decade and is scheduled to change again, so the current threshold should always be confirmed rather than assumed from a prior year. For an owner whose real estate holdings, combined with other assets, approach or exceed that threshold, the value of the property itself becomes part of the taxable estate regardless of how much appreciation the step-up in basis would otherwise shelter for heirs. Utah does not impose its own separate estate tax, but owners with property in other states or with estates near the federal threshold still need to plan around it.
Using a 1031 Exchange to Manage the Lifetime Portion
A 1031 exchange does not change estate tax exposure directly, since the deferred gain is a basis question rather than an estate-value question, but it lets an owner continue growing and consolidating real estate holdings during their lifetime without triggering the capital gains and depreciation recapture that an outright sale would create along the way. Many owners use a series of exchanges over years or decades to move from smaller, management-intensive properties into larger or more passive holdings, such as a DST allocation, while keeping the deferred gain intact until the eventual step-up resolves it at death. That sequencing, exchange during life, step-up at death, is one of the more common long-horizon strategies for appreciated commercial real estate.
An exchange completed shortly before death does not accelerate any tax, since the replacement property still receives the step-up in basis along with everything else in the estate.
Coordinating With the Broader Estate Plan
- Whether the property will pass through a trust, and how that trust holds title for 1031 purposes
- Current federal exemption levels and whether the estate is likely to approach that threshold
- Whether heirs intend to keep, sell, or exchange the property after inheriting it
- How illiquid real estate holdings fit alongside any estate tax liability that must be paid in cash
These questions sit closer to an estate attorney's expertise than a real estate one, but the real estate strategy, including whether and when to exchange, should be built around the answers rather than in isolation.
A Practical Sequence for Long-Term Owners
An owner in their sixties or seventies holding appreciated Park City commercial property with a large embedded gain often benefits from exchanging into a lower-management replacement, such as a DST position, rather than selling outright and paying the current tax bill. That preserves the eventual step-up for heirs while reducing the day-to-day burden of active property management in the meantime. It is not a strategy for everyone, since DST allocations carry their own illiquidity and are limited to accredited investors, but for the right owner it bridges the gap between wanting less hands-on responsibility and not wanting to trigger a large taxable sale.
Common 1031 Exchange Questions
Does the step-up in basis eliminate estate tax on real estate
No, the step-up in basis addresses capital gains exposure for heirs after inheriting, while estate tax is a separate calculation based on the total value of the estate above the applicable exemption threshold.
Does a 1031 exchange reduce estate tax exposure
Not directly; an exchange defers capital gains and depreciation recapture during the owner's lifetime, but the replacement property's value is still included in the taxable estate at death.
Can heirs do a 1031 exchange on inherited real estate
Yes, once heirs receive property with a stepped-up basis, they can still use a 1031 exchange on a future sale to defer any gain that accrues after the date of inheritance.
Is a DST a good fit for an older owner planning around estate tax
It can be, since a DST allocation reduces active management responsibility while preserving 1031 deferral, though it requires accredited investor status and comes with illiquidity that should be weighed against the owner's broader estate plan.
Does Utah have its own estate tax separate from the federal exemption
No, Utah does not currently impose a separate state estate tax, though owners with property in other states should confirm exposure under each state's rules.
