How Property Tax Works

Montgomery County, Kansas operates on a property tax system that serves as the primary funding source for essential local services including public schools, county government operations, emergency services, and various special districts. Property owners in Montgomery County can expect effective tax rates that generally align with Kansas's statewide average of approximately 1% of assessed value, though actual rates vary significantly based on your specific location within the county due to overlapping special taxing districts such as school districts, fire districts, and municipal services.

The county uses a market value assessment system where properties are appraised at their full market value, with taxes calculated based on this assessed value multiplied by the applicable mill levy rates. Your total property tax bill represents a combination of county-wide levies plus additional assessments from the specific taxing districts that serve your property location. It's important to understand that tax rates can vary considerably between different areas of Montgomery County depending on which school district, fire district, city, and other special districts your property falls within.

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 Montgomery County are additional property tax assessments that occur when there are mid-year changes to a property's assessed value. The most common triggers include ownership transfers where the property is reassessed at current market value, completion of new construction or major improvements, and discovery of previously unassessed improvements or structures.

When a supplemental tax is issued, it covers the difference between the previous assessment and the new assessment, prorated for the remaining portion of the tax year. For example, if you complete a $100,000 home addition in March and your total mill rate is 100 mills, you would owe approximately $750 in supplemental taxes (calculated as $100,000 × 0.10 mill rate × 9/12 months remaining in the tax year). Supplemental tax bills are typically issued within 60-90 days of the triggering event and have separate due dates from your regular annual property tax bill.

Escrow & Property Taxes

Most mortgage lenders in Montgomery County require property tax escrow accounts for borrowers with less than 20% equity in their homes. Your lender collects approximately 1/12 of your estimated annual property tax bill each month along with your mortgage payment, then pays your property taxes directly to Montgomery County when they become due on November 15th each year.

Lenders typically conduct annual escrow analyses to ensure adequate funds are collected, and may adjust your monthly payment if property taxes increase or decrease significantly. You should receive your annual property tax statement directly from Montgomery County even when using escrow, allowing you to verify the accuracy of tax calculations and ensure your lender pays the correct amount. If you pay property taxes independently without escrow, remember that the full annual amount is due by November 15th, and the county begins charging interest and penalties on December 16th for delinquent payments.
