St. Clair County Property Tax Assessment

The St. Clair County government website has information about the assessor and other offices. The county phone number is (417) 646-2315, and the courthouse address is 655 Second Street, Osceola, MO 64776. The assessor values all real estate and personal property in St. Clair County each year.

Residential real estate in St. Clair County is assessed at 19% of market value under RSMo 137.115. Commercial property is assessed at 32%. Agricultural land gets a 12% rate based on productivity. Personal property like vehicles is assessed at 33.33%. Real estate is reassessed every two years in odd-numbered years. Personal property forms go out in January and are due by March 1. Missing that deadline means a late penalty of $15 to $105, depending on the assessed value of your property.

The county clerk applies local levy rates to the assessed value. Schools, fire districts, and the county government all have separate levies. The Hancock Amendment limits how much total revenue a taxing entity can collect without voter approval. If property values go up a lot in a reassessment year, the levy must roll back.

St. Clair County Tax Appeals and Credits

If you think your St. Clair County assessment is too high, start by contacting the assessor. If an informal talk does not fix the issue, file with the Board of Equalization by the second Monday in July. Bring comparable sales or a recent appraisal.

If the board does not lower your value, appeal to the Missouri State Tax Commission by September 30. There is no fee for residential appeals. Missouri also offers a Property Tax Credit through the Missouri Department of Revenue. The max credit is $1,100 for homeowners and $750 for renters. It is based on income and taxes paid. The Missouri State Assessors Association has a directory of all county assessor offices. The Missouri Association of Counties lists all St. Clair County officials.

St. Clair County Delinquent Tax Sales

When property taxes go unpaid for two or more years in St. Clair County, the collector holds a tax sale. Delinquent real estate parcels are offered at public auction, typically in August. The buyer pays back taxes and gets a Certificate of Purchase. The original owner has a redemption period to pay the amount plus interest. If the property is not redeemed, the buyer can apply for a Collector's Deed. These procedures are governed by Chapter 140 of the Missouri Revised Statutes.

Missouri law does not prorate property taxes for mid-year moves. If you lived in St. Clair County on January 1, you owe the full year of taxes in that county, even if you moved out in February. New residents who were not in Missouri on January 1 can get a non-assessment waiver from the assessor's office for their first year.
