Kansas Rental Income Tax: What Out of State Landlords Owe on KS Side Rentals

Buy a duplex in Overland Park or a cash flow rental in Kansas City, Kansas, and most out of state owners assume the tax picture looks like the Missouri side of the metro. It does not. Kansas runs its own income tax code, its own nonresident filing form, and its own rate schedule, and none of it cares which state cashed the earnest money check. If your rental sits in Johnson County or Wyandotte County, Kansas wants a return even if you have never set foot in the state.

This is the Kansas mirror of the Missouri rental income tax question we get from the same investors, and the mechanics are close but not identical. Kansas sources rental income to the property, not to the owner, taxes that profit at 5.2 percent or 5.58 percent depending on the bracket, and lets depreciation and operating expenses reduce the number before the state ever applies its nonresident allocation formula. We manage properties in Overland Park, Lenexa, Shawnee, and Kansas City, Kansas alongside our Missouri side portfolio, and the filing gap we see most is not a missed payment. It is a missed return entirely, filed years late once the Kansas Department of Revenue sends a notice.

This post covers the Kansas income tax side only. Jackson County and Johnson County property tax assessments, appeals, and payment deadlines are their own topic, covered on our Kansas City landlord compliance page and in our dedicated property tax coverage on the blog.

What Is Kansas Rental Income Tax and Am I a Nonresident Who Owes It?

Kansas imposes its individual income tax on net profit from any rental property physically located in the state, regardless of where the owner lives, banks, or files a federal return. The Kansas Department of Revenue defines this as Kansas source income: income from real or tangible personal property located in Kansas is taxable to Kansas whether the recipient is a resident, a part year resident, or a full nonresident.

That rule pulls in every out of state owner of a Shawnee single family home, a Lenexa fourplex, or a Kansas City, Kansas duplex the moment the property produces net rental profit. There is no minimum door count and no minimum dollar threshold that exempts a small portfolio. One rental with one dollar of Kansas source taxable profit creates a Kansas filing obligation, a rule the Kansas Department of Revenue lays out directly in its 2025 individual income tax booklet.

That nonresident status applies even if you have never set foot in the state. Kansas defines a nonresident as anyone whose permanent domicile is outside Kansas, and nonresidents are taxed only on their Kansas source income, not on their wages, other rentals, or investment income earned elsewhere. Practically, this means a Dallas based investor with a Lenexa rental and no other Kansas ties still files a Kansas nonresident return reporting only the Kansas property, while every dollar of Texas income stays off the Kansas form entirely.

What Kansas Tax Rate Applies to Rental Profit in 2025 and 2026?

Kansas collapsed its old three bracket system into two brackets effective with the 2024 tax year, and those are the rates in place for 2025 returns filed in 2026: 5.2 percent on the first $23,000 of taxable income for single filers and married filing separately ($46,000 for married filing jointly), and 5.58 percent on taxable income above that threshold. There is no separate, lower rate carved out for rental or passive income. Rental profit is taxed at the same rates as wages once it lands on the Kansas return.

Kansas lawmakers passed a trigger mechanism in 2025 that would step both rates down toward a flat 4 percent as state revenue clears specific surplus benchmarks, but the reduction only activates in a year the state hits its trigger, and independent analysis of the fund balance did not expect the first cut before fiscal year 2026 collections were confirmed, according to Tax Foundation's coverage of the reform. Do not assume a lower rate applies to a given tax year. Confirm the current bracket on the Kansas Department of Revenue's income tax booklet before you file.

How Do I Calculate the Kansas Source Percentage on My Return?

Nonresidents do not simply pay Kansas tax on the rental profit in isolation. Kansas Schedule S, Part B walks through a two step method: first, the state computes what the tax would be if all of your income, from every state, were taxed at Kansas rates, then it multiplies that hypothetical tax by a nonresident allocation percentage equal to your Kansas source income divided by your total income from all sources.

Here is the mechanism with numbers. Say a Missouri based owner earns $85,000 in Missouri wages and nets $9,000 in Kansas rental profit from a Shawnee property, for total income of $94,000. The Kansas source percentage is 9,000 divided by 94,000, or roughly 9.6 percent. Kansas calculates tax on the full $94,000 at its brackets, then applies that 9.6 percent allocation to arrive at the actual Kansas liability, before the state's own standard deduction and exemption amounts reduce the number further. The mechanism matters because it means a high income year from a job or a business in another state raises the hypothetical tax base even though none of that outside income is ultimately taxed by Kansas.

How Do Depreciation and Operating Expenses Flow Through to the Kansas Number?

Kansas builds its return on top of federal adjusted gross income, so the net rental profit or loss you already calculated on federal Schedule E, after mortgage interest, repairs, management fees, and depreciation, is the starting figure Kansas works from. Kansas does not require a separate state depreciation schedule for a standard residential rental building depreciated straight line over the federal 27.5 year life.

Run the math on a Kansas City, Kansas rental with a $250,000 depreciable structure basis, land value excluded: $250,000 divided by 27.5 years is $9,091 in annual depreciation, deducted federally before Kansas ever touches the number. That deduction, plus the 50 percent of first month's rent lease up fee and the tiered management fee an owner pays for professional oversight, both reduce the federal Schedule E profit that becomes the Kansas source income figure. Kansas does carry its own state specific expensing election on Schedule S, Part A, separate from federal bonus depreciation, so an owner running cost segregation or heavy first year write offs should confirm the treatment with a preparer rather than assume full federal conformity on every line.

Do I Owe Kansas Tax Twice If I Live in Missouri or a Third State?

No, not if the credit is claimed correctly, though the sequence matters. Kansas taxes the rental profit because the property sits in Kansas. Your home state then typically allows a credit for the tax you already paid to Kansas on that same income, so the profit is not taxed twice at full rate in both states.

For a Missouri resident, that credit runs through Form MO CR, the Missouri resident credit for taxes paid to another state as described on the Missouri Department of Revenue nonresident page, and it requires attaching a copy of the completed Kansas return. The Kansas return has to be finished first because the credit calculation depends on the actual Kansas tax paid, not the withholding or an estimate. Owners who live in a third state entirely, say a California or Illinois resident with a Kansas rental, follow the same logic under their own state's equivalent credit, but the credit mechanics, caps, and forms vary by state of residence and should be verified against that state's revenue department rather than assumed from the Missouri example.

What Forms Do I File and What Is the Filing Sequence?

Nonresident owners file Form K-40 along with Schedule S, Part B, reporting Kansas source rental income in the right hand column and total income from all sources in the left hand column to establish the allocation percentage described above. A copy of the federal return, including Schedule E, typically accompanies the filing. Verify the current year's due date and any extension conformity directly on the Kansas Department of Revenue's site before you file, since deadlines and extension rules can shift year to year.

The order matters for anyone claiming a credit in a second state: complete the Kansas nonresident return first, then use the finished Kansas figures to complete the resident credit form in the state where you actually live.

How Does This Compare to the Missouri Side of the Line?

The two states share the core sourcing idea, income from real property is taxed where the property sits, but the mechanics differ enough that an owner with rentals on both sides of the state line is filing two genuinely different nonresident forms, not one form twice.

Should I Hire a Kansas Specific Preparer or Can My Home State CPA Handle This?

A CPA licensed and practicing in your home state can absolutely prepare a Kansas nonresident return. Kansas does not require an in state preparer. What matters is experience with the specific mechanics above, the total income versus Kansas source income allocation, the credit sequencing with your resident state, and the current bracket thresholds, since those numbers move when the legislature acts. An out of state investor with rentals in both Overland Park and, say, Raytown or Independence on the Missouri side is effectively running two state tax relationships from one portfolio, and asking a preparer directly whether they have filed a Kansas Schedule S before is a fair, specific question to ask before tax season starts.

None of this changes how the property itself should be run day to day. Rent collection, maintenance, and lease compliance on a Johnson County or Wyandotte County rental work the same whether the owner lives in Missouri, Texas, or California, and our Kansas property management team handles that side while an owner's tax preparer handles the return.
