Heirs who inherit a house or a piece of investment real estate in Michigan often assume they are about to face a large tax bill on decades of appreciation their parents or grandparents never paid tax on. Most of the time that assumption is wrong, because of a rule most people have never heard of until it applies to them.
The Stepped-Up Basis Rule
When someone inherits real property, the tax basis generally resets to the property's fair market value on the date of the original owner's death, not the amount that owner originally paid for it decades earlier. A Detroit rental house bought for 40,000 dollars in the 1980s and worth 260,000 dollars at the owner's death passes to the heir with a basis of roughly 260,000 dollars, which means the decades of appreciation that happened before the death is never taxed at all, to anyone. If the heir sells shortly after inheriting, at or near that stepped-up value, there is often little or no capital gain to tax in the first place.
Where Heirs Still Owe Something
The stepped-up basis erases prior appreciation, but it does not erase gain that accrues after the date of death. An heir who inherits a Grand Rapids duplex, holds it for three more years while it continues to appreciate, and then sells owes capital gains tax on the growth that happened during those three years of ownership, calculated the normal way against the stepped-up basis rather than the original purchase price.
- appreciation before death, erased entirely by the stepped-up basis
- appreciation after death and before sale, taxed normally
- any depreciation the heir claims during their own ownership, subject to recapture at sale
- Michigan's flat 4.25 percent state rate applied to whatever gain remains
When a 1031 Exchange Still Makes Sense for an Heir
Because the basis step-up already wipes out the biggest source of taxable gain, many heirs sell inherited Michigan property with minimal tax exposure and do not need an exchange at all. An exchange becomes worth considering when the heir holds the property for a period of time first, letting it appreciate further, or when multiple heirs inherit a property together and one wants to defer their share of a later sale into a different investment. A common pattern is siblings who inherit a parcel of farmland or a small commercial building together, hold it as rental property for a few years while deciding what to do, and then use individual 1031 exchanges when they eventually sell and want to redirect their share into separate replacement properties.
Sorting Out the Numbers Before Listing
The first step for any Michigan heir is establishing the actual fair market value at the date of death, usually through an appraisal or a documented comparable analysis, since that figure becomes the new basis for every future calculation. Once that number is set, it becomes much clearer whether a straightforward sale makes sense or whether continued ownership, and eventually an exchange, fits the heir's goals better than an immediate sale would.
Timing matters too. An heir who sells within a year of the date of death, close to the stepped-up value, generally faces a small tax bill regardless of the property's history. An heir who holds the property for several years while values keep climbing across a market like Grand Rapids or Ann Arbor is building new taxable gain the whole time, which is exactly the scenario where planning ahead for a possible exchange starts to matter more than it did the day the inheritance closed.
Common 1031 Exchange Questions
Do I owe capital gains tax on the full value of a house I inherited in Michigan?
Usually not on the appreciation that happened before the original owner's death, since the basis generally steps up to fair market value at death. You would only owe tax on appreciation that happens after you inherit it.
How is fair market value determined for a stepped-up basis on Michigan property?
Typically through a professional appraisal dated at or near the date of death, or in some cases a documented comparable sales analysis, since that figure becomes the new basis for all future gain calculations.
Can I do a 1031 exchange on inherited property immediately after receiving it?
You can, though since the stepped-up basis often means little or no gain exists yet at that point, an exchange right away may not provide much benefit compared to simply selling if that is your goal.
What if multiple siblings inherit the same Michigan property together?
Each sibling generally holds their share with the same stepped-up basis and can decide independently whether to sell for cash or direct their portion into a separate 1031 exchange when the property eventually sells.
Does depreciation I claim after inheriting a rental property get taxed later?
Yes, any depreciation you personally claim during your ownership becomes subject to recapture when you eventually sell, separate from and in addition to whatever appreciation gain occurs after the date you inherited it.
