Assessment lists go out in January each year. You must submit your personal property list by March 1 to avoid a penalty. If you file late, the penalty ranges from $15 for assessed values under $1,000 up to $105 for values above $9,000, as set by RSMo 137.280.

Pay Putnam County Property Taxes Online

You can pay Putnam County property taxes online at Municipal Online Payments. The portal is powered by Tyler Technologies and accepts electronic payments around the clock. Credit cards and electronic checks are accepted, though processing fees apply. The county does not keep these fees.

Tax bills go out in November and are due by December 31. The postmark on your check determines whether the payment is on time. If you do not get your bill by early December, contact the collector's office. Not getting a bill does not excuse you from paying. You can also pay in person at the courthouse during office hours or drop a check in the mail.

The Missouri Association of Counties has a full directory for Putnam County offices including the collector, assessor, and clerk.

Note: Missouri law does not prorate property taxes if you move mid-year, so the full year is owed in the county where you lived on January 1.

Property Tax Assessment Rates in Putnam County

Putnam County follows the same state assessment rates as every other Missouri county. Residential real estate is assessed at 19% of market value. Commercial property is at 32%. Agricultural land gets the 12% rate based on productivity. Personal property like cars and trucks is assessed at 33.33% of value. Farm equipment and livestock use a 12% rate, and historic vehicles are at 5%. These rates are defined in RSMo 137.115.

The county clerk applies local levy rates to the assessed value. Each taxing district sets its own levy. Schools, fire districts, and the county government all have separate levies. That means two parcels with the same market value in different parts of Putnam County may have different tax bills. The Hancock Amendment caps how much total revenue a taxing entity can collect, so if values go up sharply in a reassessment year, the levy must roll back.

Appeal Putnam County Tax Assessments

If you think your Putnam County property is assessed too high, start by contacting the assessor. If an informal discussion does not resolve it, file an appeal with the Board of Equalization by the second Monday in July. Bring comparable sales, photos, or a recent appraisal to support your case.

If the board does not reduce your value, you can appeal to the Missouri State Tax Commission by September 30. There is no charge for residential appeals at the state level. The Missouri Department of Revenue also offers a Property Tax Credit for qualified seniors and disabled individuals, with a max credit of $1,100 for homeowners.
