How Property Tax Works

Sedgwick County, Colorado operates under the state's property tax system, which funds essential local services including schools, fire protection, law enforcement, and infrastructure maintenance. Property taxes are assessed annually on the actual value of real estate as of January 1st, with different mill levy rates applied based on your specific location within the county and the various special taxing districts that serve your area.

The county's property tax rates vary significantly depending on which school district, fire district, and other special taxing jurisdictions serve your property. For 2025, total mill levy rates in Sedgwick County range from approximately 114 mills to over 149 mills, translating to effective tax rates between 1.14% and 1.49% of assessed value. Your actual tax bill depends on your property's assessed value (typically around 7.15% of market value for residential properties) multiplied by the combined mill levy rate for all taxing districts serving your location.

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 Sedgwick County are additional property tax bills issued when there are significant changes to your property's assessed value during the tax year. This typically occurs due to new construction, major renovations, or changes in property ownership that trigger a reassessment. The supplemental tax represents the difference between what you've already paid and what you owe based on the updated assessment.

For example, if you complete a $100,000 home addition mid-year, the county assessor will issue a supplemental assessment for the increased value. If your mill levy rate is 140 mills and the addition increases your assessed value by $7,150 (typical 7.15% assessment ratio), your supplemental tax would be approximately $1,001 ($7,150 × 0.140). Supplemental taxes are prorated based on the number of months remaining in the tax year when the change occurred.

Escrow & Property Taxes

If you have a mortgage, your lender likely requires property taxes to be paid through an escrow account. Your monthly mortgage payment includes a portion that goes into this escrow account, which your lender uses to pay property taxes on your behalf when they become due on January 1st. Lenders typically collect 1/12th of your estimated annual property tax bill each month, plus a small cushion to account for potential increases.

Your lender will conduct an annual escrow analysis to ensure the correct amount is being collected. If property taxes increase due to rising assessments or mill levy rates, your monthly escrow payment may increase. Conversely, if you successfully apply for tax credits like the homestead exemption, your escrow payments may decrease. You can verify that your lender paid your property taxes correctly by checking with the Sedgwick County Treasurer's office or viewing your account online. If you pay property taxes directly (without escrow), remember that payments can be made in two equal installments or one full payment, with the first installment due by the end of February and the second by June 15th.
