Real estate is usually the single largest asset in a family estate, and it gets treated two different ways depending on when the tax question is asked. While the owner is alive and selling, the concern is capital gains tax on appreciation. After death, the concern shifts to federal estate tax on the total value of everything owned, real estate included, though the two rarely apply to the same dollar of gain because of how basis resets at death.
Who Actually Owes Federal Estate Tax
The federal estate tax exemption is high enough that most families never owe it. For 2026, an individual can pass several million dollars in total assets, real estate, investments, business interests, everything combined, without triggering federal estate tax, and a married couple can generally combine exemptions. Tennessee does not have a separate state estate or inheritance tax, so a Nashville-area family's exposure is limited to the federal threshold. Owners with substantial commercial real estate portfolios in areas like Brentwood or Green Hills are the ones most likely to bump against the exemption, particularly if the exemption amount is reduced by future legislation.
The Stepped-Up Basis And Why It Matters More Than People Expect
When real estate passes to an heir at death, its basis generally resets to fair market value on the date of death rather than carrying forward the original purchase price. An heir who inherits a Nashville rental the parent bought decades ago for a fraction of its current value can sell it soon after inheriting with little or no capital gains tax owed, because the built-in gain the original owner would have paid tax on is effectively erased for that heir. This is a separate benefit from the federal exemption amount and applies regardless of whether the estate owes any estate tax at all.
- Basis resets to date-of-death fair market value for most inherited property
- The built-in gain the original owner deferred through a 1031 exchange also resets at death
- This benefit applies to the heir, not to the original owner during their lifetime
- Estate tax exposure and capital gains exposure are calculated separately
Why Some Owners Keep Deferring Instead Of Selling
Because the stepped-up basis erases built-in gain at death, some real estate owners deliberately avoid selling appreciated property during their lifetime and instead keep deferring the gain through successive 1031 exchanges, sometimes referred to informally as swap-until-you-drop. A Nashville-area landlord who has exchanged the same equity through several properties over thirty years can, in many cases, pass the final replacement property to heirs with the entire deferred gain wiped out at the stepped-up basis, rather than ever paying the capital gains and recapture tax that would have been due on a lifetime sale.
Where This Strategy Has Real Limits
This approach is not a guaranteed outcome and depends on tax law staying roughly as it is, which is not assured over a multi-decade holding period. It also requires the owner to keep managing real estate, or transition into a passive Delaware Statutory Trust interest through a 1031 exchange, rather than cashing out for liquidity or diversification. Owners with larger estates should also coordinate any exchange strategy with estate planning counsel, since combining lifetime deferral with the federal exemption and any available portability election between spouses requires more than a single transaction to get right.
A qualified intermediary and a CPA familiar with both exchange rules and estate planning should be brought in well before the final property in the chain is ever listed, since the sequencing between the last exchange and the eventual transfer to heirs can affect whether the deferred gain actually resets cleanly.
Common Questions
Does Tennessee charge a separate estate or inheritance tax?
No. Tennessee has no state estate tax or inheritance tax, so a Nashville-area family's exposure is limited to the federal estate tax exemption threshold.
Does the stepped-up basis apply even if the original owner deferred gain through 1031 exchanges for decades?
Generally yes. The deferred gain carried through successive exchanges typically resets to fair market value at the owner's death, along with the rest of the property's basis, for the heir who inherits it.
Do heirs owe capital gains tax if they sell inherited real estate right away?
Usually little to none on the built-in gain that existed before death, since the basis has already reset to date-of-death value. Any appreciation after the date of death would still be taxable.
Can a Delaware Statutory Trust interest still receive a stepped-up basis at death?
Generally yes, since a DST interest acquired through a 1031 exchange is treated as real property ownership for tax purposes and follows the same stepped-up basis rules as directly held real estate.
