How Property Tax Works

Osborne County, Kansas operates under the state's property tax system to fund essential local services including schools, roads, public safety, and county operations. Property taxes are calculated based on assessed values determined by the county assessor, with the current effective tax rate for 2025 set at approximately 1.6% of assessed value. This rate represents the combined levy from multiple taxing jurisdictions including the county, school districts, townships, and various special districts.

Actual tax rates vary significantly by location within Osborne County due to different combinations of special taxing districts such as school districts, fire districts, cemetery districts, and municipal services. Property owners should expect their specific rate to differ from the county average based on which services and districts apply to their property location. The county assessor determines property values annually, while elected officials from various taxing jurisdictions set the mill levies that determine your final tax obligation.

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental taxes in Osborne County are additional property tax assessments that occur when there are changes to property ownership, improvements, or new construction outside the regular assessment cycle. These are typically triggered by property transfers, completion of new buildings, major renovations that increase property value, or corrections to previous assessments.

Supplemental taxes are calculated by applying the current tax rate to the difference between the new assessed value and the previous assessed value, prorated for the portion of the tax year remaining. For example, if you complete a $100,000 home addition in October and your tax rate is 1.6%, you would owe supplemental taxes of approximately $800 ($100,000 × 1.6% × 6/12 months remaining in the tax year). These supplemental bills are issued separately from regular tax statements and have their own due dates, typically 30 days from the issue date.

Escrow & Property Taxes

Most mortgage lenders in Osborne County require property tax escrow accounts for borrowers with less than 20% down payment. Your lender collects monthly property tax payments along with your mortgage payment, depositing these funds into an escrow account. The lender then pays your property taxes directly to Osborne County when they become due in April.

Lenders typically conduct an annual escrow analysis to ensure adequate funds are collected, which may result in payment adjustments if taxes increase or decrease. Property owners are responsible for providing updated tax information to their lenders and should verify that payments are made timely. If you pay taxes directly without escrow, you're responsible for the full payment by the April 15 deadline to avoid interest and penalties.
