How Property Tax Works

Knox County, Nebraska operates on an annual property tax system that funds essential local services including schools, county operations, emergency services, and infrastructure maintenance. Property taxes are the primary revenue source for these vital community services, with taxes calculated based on assessed property values and local tax rates set by various taxing authorities.

The property tax rate for Knox County varies by location within the county due to different combinations of special taxing districts such as school districts, fire districts, and municipal services. For the 2025 tax year, the base county rate is 0.132144 per $100 of assessed valuation, though your total effective rate will likely be higher when school district levies and other special assessments are included. Property owners should expect their actual tax rate to vary depending on which specific taxing districts serve their property location.

Property taxes in Knox County are assessed annually based on market value as of January 1st, with payments due in two installments throughout the year. The county follows Nebraska's standard assessment practices, with most residential properties assessed at approximately 100% of market value, though various tax credits may be available to qualifying property owners who submit the required applications.

Supplemental Tax Bills

Supplemental taxes in Knox County are additional property tax assessments that occur when there are changes to property ownership, improvements, or new construction after the January 1st assessment date. These taxes ensure that property tax obligations are properly allocated when properties change hands or increase in value due to improvements during the tax year.

Supplemental taxes are most commonly triggered by: property sales that result in reassessment, completion of new construction or major renovations, and additions or improvements that increase property value. The supplemental tax is calculated based on the difference between the old assessed value and the new assessed value, prorated for the remaining months in the tax year.

For example, if you purchase a home in Knox County in July that was previously assessed at $200,000 but now has a market value of $300,000, you would receive a supplemental tax bill for the $100,000 difference in assessed value, calculated for the remaining 6 months of the tax year. This ensures that you pay the appropriate amount based on the property's current value rather than the previous owner's assessment.

Escrow & Property Taxes

Most mortgage lenders in Knox County require property tax escrow accounts to ensure timely payment of property taxes. Your lender collects 1/12th of your estimated annual property tax bill each month along with your mortgage payment, then pays your property taxes directly to Knox County when they become due.

Knox County property taxes are due in two installments: the first half payment is due by June 1st, and the second half payment is due by December 1st. Your lender will typically pay these installments on your behalf using funds collected in your escrow account. Lenders usually conduct annual escrow analyses to adjust your monthly payment based on actual tax bills and any changes in assessed value or tax rates.

If you pay your own property taxes without escrow, you're responsible for making both installment payments directly to Knox County by the due dates. Late payments are subject to penalties and interest charges. You can verify your tax amounts and payment status through the Knox County Treasurer's office, and it's important to keep records of all payments for tax deduction purposes.
