Are you finding that rising property taxes are becoming one of the biggest challenges affecting cash flow, profitability, and long-term investment planning?
You’re not alone.
While the Kansas City metro continues to attract new residents, strong housing demand and increasing property values are also creating higher tax burdens for landlords.
Taxes depend on several factors, including property valuations, local mill levies, housing market conditions, and how proactively investors manage their portfolios. What is clear, however, is that Johnson County landlords should prepare for continued pressure on operating costs this year.
According to Johnson County’s 2026 market study analysis, approximately 90% of residential properties are expected to increase in value, with average residential increases projected around 5–7%.
For rental investors, that means understanding how property taxes work and developing strategies now to protect profitability.
Our Overview:

Why Are Property Taxes Rising in Johnson County?
Property taxes in Kansas are largely based on two things:
- The appraised value of the property
- The local mill levy rate
When property values rise, tax bills often rise as well, even if mill levy rates remain relatively stable.
Johnson County’s 2026 revaluation report showed continued increases across both residential and multifamily property categories. Apartment property appraised values increased approximately 11%, while residential properties increased roughly 6% countywide.
Several factors are contributing to these increases.
- Strong Housing Demand Continues
Johnson County remains one of the most desirable areas in Kansas due to strong schools, job growth, low unemployment, and access to Kansas City metro amenities. There’s also continued residential development. Higher market values typically translate into higher appraisals.
- Multifamily Properties Face Additional Pressure
Rental demand has remained relatively healthy throughout Johnson County, particularly in cities such as Overland Park, Olathe, Lenexa, and Shawnee. County reports indicate multifamily occupancy has remained in the low 90% range while rent growth continues steadily. As apartment income and occupancy remain strong, multifamily properties may face more aggressive valuation increases.
- Local Government Budget Needs
Even when mill levies stay relatively flat, growing property values can still generate larger tax revenues. Johnson County officials have emphasized maintaining public services, infrastructure, parks, libraries, and public safety investments while managing inflationary pressures.
How Do Property Taxes Affect Rental Investors?
Property taxes directly impact rental profitability in several ways.
- Reduced Cash Flow. Higher taxes increase monthly operating expenses, reducing net income and cash flow. For investors with adjustable-rate loans, thin operating margins, older properties, or high maintenance costs, even moderate tax increases can significantly affect annual returns.
- Increased Escrow Payments. Landlords with mortgages often experience increased escrow requirements after reassessments. This can create sudden monthly payment increases that impact budgeting and reserves.
- Pressure on Rental Pricing. As expenses rise, some landlords attempt to offset costs through rent increases. However, rental pricing must still align with market conditions. Overpricing units can increase vacancy risk and tenant turnover.
How Are Kansas Property Taxes Calculated?
Many landlords misunderstand how Kansas property taxes work.
In Johnson County:
- Residential property is assessed at 11.5% of appraised value
- Commercial property is assessed at 25%
- Tax bills are then calculated using the applicable mill levy rate
Because mill levies vary by city, school district, and taxing jurisdiction, tax amounts can differ substantially across Johnson County communities.
Review Your Property Valuations Carefully
One of the most important things rental investors should do in 2026 is carefully review annual valuation notices. Do not assume the county’s valuation is automatically accurate.
- Compare nearby sales and market trends within your neighborhood. If your valuation appears significantly inflated compared to comparable properties, you may have grounds for appeal.
- Understand the appeals process. Kansas property owners have the right to appeal valuations. You’ll have to meet with the appraiser, submit your evidence, and potentially attend a formal hearing.
While landlords cannot fully control tax increases, they can improve operational performance elsewhere, which can help offset higher tax costs.
Plan for Tax Increases in Future Acquisitions
Many investors underestimate future tax exposure when purchasing rental properties.
When analyzing acquisitions in Johnson County, investors should:
- Stress-test future operating costs
- Estimate reassessed tax values
- Build larger reserve funds
- Avoid relying on outdated tax bills
A property purchased at today’s market value may eventually be reassessed much higher than the seller’s previous valuation. Conservative underwriting is increasingly important.
Keep a Long-Term Perspective
Although rising taxes create challenges, Johnson County remains one of the strongest long-term rental markets in Kansas.
Population growth, strong schools, economic development, and limited housing inventory continue supporting demand throughout much of the county.
Investors who plan carefully, manage expenses proactively, and maintain strong properties are often better positioned to navigate rising tax environments successfully.
