Inheriting a house or a piece of farmland in Missouri comes with a tax rule that catches a lot of heirs off guard, mostly because it works in their favor and nobody explains it clearly at the time. Basis in inherited property is generally reset to its fair market value at the date of the original owner's death, not carried over from what that person originally paid decades earlier. That single rule changes the entire capital gains conversation for most heirs.
How Stepped-Up Basis Actually Works
If a parent bought a St. Louis rental property for a modest price forty years ago and it is worth many times that today, an heir who inherits it does not inherit that original low basis. Instead, basis generally steps up to the property's fair market value as of the date of death, which means if the heir sells shortly afterward for close to that appraised value, there may be little or no taxable gain at all, even though the property appreciated enormously over the original owner's lifetime.
Establishing the Date-of-Death Value
The stepped-up basis is only as reliable as the documentation behind it. A formal appraisal dated as close to the date of death as practical, or values reported on an estate tax return if one was filed, are the strongest support. Heirs who wait years to sell and rely on a rough guess of what the property was worth at the time of death risk an IRS challenge to the basis they claim, particularly on higher-value Missouri farmland or commercial property where the swings in value can be significant.
Gain After the Step-Up
Any appreciation after the date of death, plus any depreciation the heir personally claims if the property becomes a rental, is treated the normal way: taxed as capital gain, or subject to recapture, when the property is eventually sold. Heirs who hold an inherited property for a while before selling, whether farmland near Cape Girardeau or a rental in Kansas City, are only taxed on the gain that accrued during their own ownership period, not the decades of appreciation that happened before they inherited it.
Missouri Tax Treatment and Multiple Heirs
Missouri does not impose a separate inheritance tax, and any capital gain from the eventual sale of inherited property is taxed like any other gain under the state's graduated income brackets. When a property passes to multiple heirs jointly, each heir generally takes a proportional share of the stepped-up basis, and disagreements among heirs about whether to sell, rent, or hold the property often matter more in practice than the tax mechanics themselves. For heirs who inherit investment or business real property and want to keep the capital invested in real estate rather than cash out, a 1031 exchange remains available on the inherited property's investment-use portion, the same as it would for any other investment property.
Common 1031 Exchange Questions
Does stepped-up basis apply to all inherited property, or only certain types?
It generally applies to most property inherited from a decedent, including real estate, though the specific rules can vary based on how the property was titled and whether it was jointly owned. An estate attorney or CPA can confirm the treatment for a specific situation.
What if the property is sold quickly after inheriting it?
A sale shortly after death, close to the appraised date-of-death value, often produces little or no taxable gain because the stepped-up basis is close to the sale price. Selling costs can even create a small deductible loss in some cases.
Do you need a formal appraisal to establish the stepped-up basis?
A dated, professional appraisal is the strongest documentation, particularly for higher-value property. Some estates rely on values reported on an estate tax return instead, if one was required.
Is Missouri farmland treated differently than a residential rental for this purpose?
The stepped-up basis rule applies the same way to farmland as to residential rental property. Farmland often carries additional considerations around equipment, mineral rights, or agricultural use that should be separated from the real estate value itself.
Can heirs use a 1031 exchange on inherited real estate?
Yes, as long as the property is held for investment or business use rather than personal use, an heir can generally use a 1031 exchange the same way any other owner of investment property would.
