How assessments work in St. Louis

The City of St. Louis assigns a value to real property for taxation based on market data, physical characteristics, and statutory standards. Assessors use sales, inspections, and standardized appraisal methods to estimate fair market value. Notices of assessed value are mailed or posted; property owners should compare the assessed value to recent sales and their property record card.

• Assessment basis: market value as of the assessment date.
• Timing: annual assessment cycles and notice dates vary by year; check official notices.
• Documentation: property record cards, recent sales, appraisal reports.

Valuation methods and common adjustments

Typical valuation approaches include comparable sales, cost approach for unique structures, and income approach for rental or commercial properties. Adjustments account for condition, lot size, and permitted uses. Exemptions or abatements (for seniors, veterans, or redevelopment) can change taxable value and must be applied through the correct office.

• Comparable sales: used for most residential parcels.
• Cost approach: for new or special-purpose buildings.
• Income approach: for rental and commercial properties.

Penalties & Enforcement

Assessment errors can lead to incorrect tax bills, penalties, and interest assessed by the Collector. Enforcement of collection and penalties is handled by the City Collector or equivalent revenue office; administrative review and formal appeals are handled by designated review bodies. Specific monetary fines or penalty schedules for assessment disputes are not provided on the cited assessor page; see the contact and appeal resources below for payment, penalties, and interest rules.City Assessor^[1]
