A landlord who has owned a duplex in Waldo or a small rental portfolio scattered across the Kansas City metro eventually runs into the same question: what does a sale actually cost after the tax bill comes due. Capital gains tax on rental property is calculated differently than a home sale, because there is no owner-occupied exclusion and because the depreciation claimed over the years gets recaptured separately from the rest of the gain.
Two Layers of Tax on One Sale
Selling a rental property triggers two distinct tax calculations that get combined on the return. The portion of gain attributable to depreciation already claimed is taxed as depreciation recapture, generally at a rate up to 25 percent, while the remaining gain above the original basis is taxed at ordinary long-term or short-term capital gains rates depending on the holding period. An investor who has owned a rental in Grandview or Belton for 10 or 15 years may find the recapture piece is larger than expected, simply because depreciation deductions compound over a long hold.
Working Out the Actual Gain
The starting basis is the original purchase price plus qualifying capital improvements, minus depreciation taken over the ownership period. From there, the net sale price after commissions and closing costs is compared against that adjusted basis to arrive at total gain. A few figures worth pulling together before running the calculation:
- original purchase price and closing costs from the acquisition
- capital improvements made during ownership, separate from repairs
- total depreciation claimed on tax returns over the hold
- expected selling costs including commission and title fees
- current mortgage payoff, which affects proceeds but not the tax calculation itself
State Line Considerations for Kansas City Landlords
Because the metro spans both Missouri and Kansas, a landlord with rentals on both sides of State Line Road needs to be aware that state tax treatment of the sale can differ even though the federal gain calculation is the same. Missouri and Kansas each have their own state income tax rules that apply to the gain, and an owner selling properties in both states in the same year should have a tax advisor confirm how each state's return treats the sale.
Deferring the Tax Through an Exchange
A 1031 exchange is the standard way rental property owners defer both the depreciation recapture and the capital gains portion of a sale, by rolling the proceeds into another qualifying investment property rather than taking a cash payout. This works for a single rental moving into a larger multifamily asset, or for several smaller rentals consolidated into one replacement property, as long as the exchange follows the identification and closing deadlines and uses a qualified intermediary to hold funds.
When Selling Outright Might Still Make Sense
Not every rental sale needs to defer the tax. An owner who is exiting real estate investing entirely, or who has losses elsewhere on their return that offset the gain, may come out ahead paying the tax now rather than carrying the deferral forward into another property. That decision usually comes down to a side-by-side comparison with a tax advisor rather than a default assumption that deferral is always better.
Common Questions
Is depreciation recapture taxed at the same rate as the rest of the capital gain?
No, depreciation recapture on real property is generally taxed at a rate up to 25 percent, separate from the long-term capital gains rate applied to the remaining gain above original basis.
Do you owe capital gains tax in both Missouri and Kansas if you sell rentals in both states?
Each state taxes the gain on property located within its borders, so a landlord selling in both states in the same year should confirm the filing requirements for each return with a tax advisor rather than assuming one filing covers both.
Can a 1031 exchange defer depreciation recapture, not just the capital gain?
Yes, a properly structured 1031 exchange defers both the depreciation recapture and the capital gains portion together, since both are part of the same deferred transaction under the exchange rules.
How does the holding period affect the tax rate on a rental sale?
Property held over a year qualifies for long-term capital gains rates, which are generally lower than the short-term rates applied to property held a year or less, though depreciation recapture is taxed under its own rate regardless of holding period.
What records should a landlord keep to calculate gain accurately at sale?
Purchase documents, records of capital improvements, and annual depreciation schedules from tax returns are the core records needed, and gathering them well before listing the property avoids a rushed calculation close to closing.
