Inheriting real estate comes with one of the more favorable rules in the entire tax code, and most heirs do not fully understand it until they are already sitting across from a closing table. The property's basis generally resets to its fair market value on the date of the original owner's death, which can erase decades of built-up gain the deceased owner would have paid tax on had they sold it themselves.
How Stepped-Up Basis Actually Works
If a parent bought a rental house decades ago for $80,000 and it is worth $450,000 at the time of their death, the heir's basis becomes $450,000, not $80,000. If the heir sells shortly after inheriting at close to that same fair market value, there is little to no capital gain to tax, even though the original owner would have owed tax on nearly $370,000 of appreciation had they sold the week before.
This step-up applies to real estate included in the decedent's taxable estate, and the value used is typically the appraised fair market value as of the date of death, or in some cases an alternate valuation date the estate elects.
What Happens to Depreciation the Original Owner Claimed
Depreciation recapture, which follows an owner during their lifetime and would have been owed on a sale, generally does not carry over to the heir. The stepped-up basis resets the recapture exposure along with the capital gains exposure, which is part of why holding appreciated rental property until death, rather than selling it during life, is such a commonly discussed estate planning strategy.
When an Heir Still Owes Tax
- The property appreciates further after the date of death and before the heir sells
- Multiple heirs inherit jointly and one wants to sell while others want to keep the property, creating a taxable buyout of shares above their stepped-up basis
- The estate elects an alternate valuation date that differs from the date of death
- Community property rules in certain states change how the step-up applies to jointly owned property
Most of an heir's tax exposure on inherited property comes from appreciation after inheriting, not from the original owner's gain, which the step-up generally erases.
Should an Heir Consider a 1031 Exchange on Inherited Property
An heir who wants to keep the value working in real estate, rather than cashing out immediately, can still use a 1031 exchange on inherited investment property, deferring any gain that accrues after the stepped-up basis date. Because the basis reset already removed most of the built-in gain, the exchange is less about avoiding a large existing liability and more about preserving flexibility to reposition into a different property, or a different market, without triggering tax on appreciation that happens between inheriting and selling.
Documentation an Heir Needs Before Selling
A qualified appraisal or comparable market analysis dated as close to the date of death as possible is the single most important document an heir can secure, since it establishes the basis the IRS will expect to see if the sale is ever questioned. Waiting years to sell without ever pinning down that value makes it much harder to prove basis later, especially if the market moved significantly in the interim.
Common Questions
Do I owe capital gains tax if I sell an inherited house right away?
Usually very little or none, because the stepped-up basis generally resets your cost basis to the fair market value at the date of death, so a quick sale near that value produces minimal taxable gain.
Does stepped-up basis apply to property held in a trust?
It depends on the type of trust and how it was structured. Property in a revocable living trust that becomes part of the decedent's estate generally still gets the step-up, while certain irrevocable trust structures may not, which makes this a detail worth confirming with an estate attorney.
What if the property was jointly owned by a married couple and one spouse dies?
In community property states, the surviving spouse often receives a full step-up on both halves of the property. In common law states, typically only the deceased spouse's half receives the step-up, leaving the surviving spouse's original basis on their portion.
Can multiple siblings who inherit a property together each do their own 1031 exchange?
Yes, if the property is properly divided into separate ownership interests known as tenants in common before the exchange, each sibling can direct their own share into a separate replacement property through their own qualified intermediary, though this needs to be structured correctly well before any sale.
