How Property Tax Works

Marion County, Kansas operates under the state's property tax system where property taxes serve as the primary funding source for local government services, including schools, roads, law enforcement, and county operations. The county's property tax system is administered by the County Assessor's office, which determines property values, and the County Treasurer's office, which collects taxes.

Property tax rates in Marion County vary significantly by location within the county due to different combinations of special taxing districts, including school districts, cities, townships, and improvement districts. While Kansas maintains a statewide average effective rate of approximately 1%, Marion County's actual rates depend on your specific property location and the taxing jurisdictions that serve your area. Property owners should expect their effective tax rate to differ based on which school district, city limits, and special districts apply to their property.

All property taxes in Marion County are due annually by November 15th, with delinquent taxes accruing interest after this date. The county offers online payment options through the Kansas Property Tax Payment system for taxpayer convenience.

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 Marion County occur when there are changes to property ownership, new construction, or improvements that alter a property's assessed value during the tax year. These situations trigger a recalculation of the annual tax bill to account for the change in assessed value or ownership period.

Common triggers for supplemental taxes include: completion of new construction or major renovations, property splits or combinations, successful assessment appeals that increase value, and corrections to property characteristics discovered during the year. The supplemental tax is calculated by applying the current year's tax rate to the change in assessed value, prorated for the portion of the tax year affected by the change.

For example, if a property owner completes a $50,000 addition to their home in March, and the county assesses this improvement at $40,000, a supplemental tax would be calculated on the $40,000 increase in assessed value for the remaining months of that tax year. The property owner would receive a supplemental tax bill in addition to their regular annual property tax bill.

Section 5

Escrow & Property Taxes

Most mortgage lenders in Marion County require property tax escrow accounts for loans with less than 20% down payment, though some lenders may require escrow regardless of down payment amount. Your lender collects monthly escrow payments as part of your mortgage payment, typically 1/12th of the annual property tax bill plus a cushion amount allowed by federal law.

Property taxes in Marion County are due November 15th annually. Lenders typically pay property taxes on behalf of borrowers in late October or early November to ensure timely payment and avoid penalties. After paying your property taxes, your lender should provide you with a copy of the payment receipt and tax bill for your records.

Lenders are required to perform annual escrow analyses to ensure adequate funds are collected. If your property taxes increase significantly due to reassessment or rate changes, your lender may require increased monthly escrow payments or a lump sum payment to cover any shortage. Property owners can verify their tax payments and balances by contacting the Marion County Treasurer's office or checking online through the Kansas Property Tax Payment system.
