How Property Tax Works

Grant County, Kansas operates under the state's property tax system to fund essential local services including schools, roads, law enforcement, fire protection, and county government operations. Property taxes in Grant County are calculated based on assessed value multiplied by the local tax rate, with Kansas using an assessment ratio of 11.5% of fair market value for residential properties.

The effective tax rate in Grant County typically ranges around 1% of market value, though this can vary significantly depending on your specific location within the county. Different areas are served by various special taxing districts including school districts, fire districts, townships, and municipalities, each of which may impose additional levies beyond the base county rate. Property owners should verify their specific tax rate by identifying all applicable taxing districts for their property 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 Grant County are additional tax bills issued when property undergoes changes that affect its assessed value during the tax year. Common triggers include new construction, property improvements, ownership transfers that prompt reassessment, or corrections to the original assessment.

When supplemental taxes are levied, they are calculated by applying the current tax rate to the difference between the new assessed value and the original assessed value, prorated for the portion of the tax year remaining. For example, if you complete a $100,000 home addition in July, you would owe taxes on the increased assessed value (11.5% of $100,000 = $11,500 additional assessed value) for the remaining half of the tax year. This would result in a supplemental bill of approximately $575 if your total tax rate is 100 mills ($11,500 × 0.100 ÷ 2 = $575).

Escrow & Property Taxes

Most mortgage lenders in Grant County require property tax escrow accounts to ensure timely payment of property taxes. Your lender collects monthly payments equal to 1/12th of your annual property tax bill, holds these funds in an escrow account, and pays your taxes directly to Grant County when due.

Property taxes in Grant County are typically due in two installments: the first half due by April 1st and the second half due by October 1st, with final payment required by December 31st of the tax year. Your lender will receive tax bills directly and make payments according to this schedule. Lenders are required to provide annual escrow analysis statements showing account activity and any required payment adjustments based on actual tax amounts versus estimates. If your taxes increase due to reassessment or rate changes, your monthly escrow payment may be adjusted accordingly.
