How Property Tax Works

Linn County, Missouri operates on an ad valorem property tax system that funds essential county services including schools, public safety, infrastructure, and local government operations. Founded in 1839 and named after Missouri Senator Lewis Linn, the county assesses property taxes based on the state's base rate of approximately 1% of assessed value, though actual rates vary significantly by location within the county.

Property owners should note that their total tax rate depends on their specific location within Linn County, as various special taxing districts (school districts, fire districts, ambulance districts, and other municipal services) overlay additional levies on the base county rate. The Missouri State Auditor's Office reports that ambulance districts alone can add varying rates, with 103 districts maintaining rates from the prior year while others have revised rates upward or downward. This means two properties of identical value in different parts of Linn County may have substantially different tax bills based on the special districts serving their area.

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 Missouri are additional property tax assessments that occur when there are changes in property ownership, new construction, or improvements made to existing properties during the tax year. These supplemental bills are calculated based on the difference between the old and new assessed values, prorated for the remaining months in the tax year.

For example, if you purchase a home in Linn County in March that was previously under-assessed, or if you complete a major renovation that increases your property's assessed value, the county assessor will issue a supplemental tax bill. The supplemental tax is calculated by taking the difference in assessed value, multiplying by your area's total tax rate, then prorating for the months remaining in the tax year. If your assessed value increased by $50,000 and your total tax rate is 1.2%, with 9 months remaining in the tax year, your supplemental tax would be approximately $450 ($50,000 × 0.012 × 9/12).

Escrow & Property Taxes

Most mortgage lenders in Linn County require borrowers to maintain an escrow account for property tax payments, especially for loans with less than 20% down payment. Your lender collects monthly property tax payments along with your mortgage payment, typically 1/12th of your annual tax bill. The lender holds these funds in an escrow account and pays your property taxes directly to Linn County when they become due in December.

Property taxes in Missouri are levied in October with bills mailed in November and due by December 16th. Your mortgage servicer will typically pay the full annual amount by this deadline to avoid penalties. Lenders are required to provide an annual escrow analysis showing how your escrowed funds were used and any adjustments needed for the coming year. If your property taxes increase due to reassessment or rate changes, your monthly escrow payment will be adjusted accordingly, usually with a 60-day notice from your lender.
