How Property Tax Works

Sherman County, Kansas operates on an annual property tax system that funds essential county services including education, law enforcement, emergency services, and infrastructure maintenance. Property taxes are the primary revenue source for local government operations and school districts throughout the county. The effective tax rate in Sherman County is approximately 11.257 mills (1.1257%) for the 2025 levy year, though this represents a baseline rate that varies significantly by location within the county.

Actual property tax rates vary considerably depending on your specific location within Sherman County due to overlapping special taxing districts. These districts may include school districts, fire districts, cemetery districts, and other municipal service areas, each with their own approved levy rates. Property owners should expect their total effective rate to differ from the base county rate based on which special districts serve their property location.

Section 4

Supplemental Tax Bills

Supplemental property taxes in Sherman County are triggered by changes in property ownership, completion of new construction, or significant property improvements that increase assessed value during the tax year. When these events occur, the county assessor calculates additional taxes owed on the increased assessed value for the remaining portion of the current tax year.

For example, if you complete a $100,000 home addition in March that increases your assessed value by $11,500 (using Kansas's 11.5% assessment ratio for residential property), and your local tax rate is 30 mills, you would owe supplemental taxes of approximately $345 for the remaining 9 months of that tax year. Supplemental tax bills are typically issued within 60 days of the assessment change and follow the same payment schedule as regular property taxes.

Escrow & Property Taxes

Most mortgage lenders in Sherman County require borrowers to maintain an escrow account for property tax payments. Lenders collect monthly payments equal to 1/12 of your estimated annual property tax bill and pay the county directly when taxes are due. The escrow account is analyzed annually, and your monthly payment may be adjusted based on actual tax bills and account balance.

Property taxes in Sherman County are due annually by November 15, though the county allows payment in three equal installments due November 15, February 15, and May 15 to avoid interest charges. Lenders typically make the full annual payment in November or utilize the installment schedule. Property owners should verify their mortgage servicer is making timely payments and receiving current tax bills to avoid penalties or liens.
