An investor listing a warehouse near the Fairfax Industrial District or a small office building along College Boulevard usually wants one number before the sale goes forward: what will actually be owed once the deal closes. Capital gains tax on investment property has more moving parts than most sellers expect, and the answer depends on the property type, how long it was held, and whether the proceeds are going into another investment or out of real estate entirely.
Federal Capital Gains Layer
The federal government taxes the gain above adjusted basis at long-term capital gains rates for property held more than a year, with the specific rate depending on the seller's total taxable income for the year. Below that threshold, short-term gains are taxed as ordinary income, which is a meaningfully higher rate for most investors, so timing a sale to clear the one-year mark is worth checking on any property purchased recently.
Depreciation Recapture on Commercial and Rental Assets
Any depreciation claimed during ownership gets taxed separately as recapture, at a rate that can run higher than the long-term capital gains rate on the rest of the gain. This applies to fully depreciable improvements on commercial buildings the same way it applies to residential rentals, and it is often the piece investors underestimate because it is calculated against total depreciation taken rather than against the sale price.
Net Investment Income Tax
Higher-income sellers may also owe the net investment income tax on top of the capital gains rate, an additional federal surtax that applies once modified adjusted gross income crosses a set threshold. This layer catches some Kansas City investors off guard on a large single-property sale, since the sale itself can be enough to push total income over the threshold for that year even if regular income is otherwise moderate.
State Tax on Top of Federal
Missouri and Kansas each apply their own state income tax to the gain, on top of the federal layers above. An investor selling a property on the Missouri side, such as in the River Market or Crossroads district, files under Missouri's rules, while a property in Overland Park or Olathe falls under Kansas's, and an investor with holdings scattered across the metro should not assume the two states tax the gain identically.
Deferring All of the Above With a 1031 Exchange
A 1031 exchange defers the federal capital gains tax, the depreciation recapture, and generally the state tax as well, by rolling proceeds into a qualifying replacement property instead of taking a payout. This does not make the tax disappear permanently, but it postpones every layer described above until the replacement property is eventually sold outright, which gives an investor more capital to redeploy immediately after the original sale closes.
Weighing a Sale Against a Hold
Some investors run the numbers and decide the tax cost of selling now is worth it for the flexibility of cash in hand, particularly if they are consolidating a portfolio or moving into a different asset class that does not fit neatly into an exchange timeline. Others find that stacking all four tax layers together makes deferral through an exchange the more obvious choice, especially on a property that has been depreciated for a decade or longer.
Common Questions
Does the net investment income tax apply to every investment property sale?
No, it only applies once a seller's modified adjusted gross income for the year crosses the federal threshold, which a large single-property sale can trigger even for an investor with otherwise moderate income.
Are Missouri and Kansas capital gains tax rates on real estate the same?
They are not identical, since each state sets its own income tax rates and rules, so an investor with property on both sides of the metro should have a tax advisor confirm the treatment in each state separately.
Can a 1031 exchange defer the net investment income tax along with capital gains?
A properly structured exchange defers the gain that would otherwise contribute to net investment income for that tax year, though the specific treatment should be confirmed with a tax advisor based on the investor's full income picture.
How is depreciation recapture different from the rest of the capital gain on a commercial sale?
Recapture is calculated against the total depreciation claimed during ownership and taxed at its own rate, separate from the long-term capital gains rate applied to appreciation above the original basis.
Is it ever better to just pay the tax instead of doing a 1031 exchange?
It can be, particularly for an investor exiting real estate entirely or one with offsetting losses elsewhere on their return, which is why the decision is usually run as a side-by-side comparison rather than assumed.
