Missouri residents often have questions like:

This guide answers all these questions using official sources, ensuring you get accurate and actionable information.

What Is Personal Property Tax in Missouri?

Personal property tax is a tax on movable property. Unlike real estate tax, which is levied on land and buildings, personal property tax applies to items that can be moved. In Missouri, the primary items subject to this tax include:

• Vehicles: Cars, trucks, motorcycles, recreational vehicles.
• Boats and Watercraft: Including personal watercraft like jet skis.
• Trailers: Utility trailers, campers, and travel trailers.
• Business Equipment: Machinery, tools, or equipment used for commercial purposes.

The tax is assessed based on the property’s value. Missouri law requires that personal property be assessed at 33.33% of its market value (kcmo.gov).The amount collected contributes to local infrastructure, schools, and community programs, making compliance important for all residents.

Who Must Pay Personal Property Tax in Missouri?

Personal property tax applies to residents who own taxable personal property as of January 1 of the tax year.

Examples of liable owners:

• Car owners
• Boat or trailer owners
• Business owners with machinery or equipment
• Residents who keep livestock or other taxable business property

Even if you acquire property after January 1, you may not owe tax for that year, but all properties owned on January 1 are taxable. Missing the declaration deadline or failing to pay can lead to penalties.

Missouri Personal Property Tax Rates (2025)

The tax rate varies by county and is affected by local taxing districts. According to World Population Review, the median property tax paid in Missouri is $1,198.84. However, individual rates differ:

• St. Louis City: Rates are higher due to dense urban infrastructure (stlouis-mo.gov).
• Jackson County: Recent policy discussions aim to cap commercial property tax increases at 15% to prevent sudden spikes (axios.com).

How to calculate your personal property tax:

1. Determine your property’s market value.
2. Multiply by 33.33% to get the assessed value.
3. Multiply the assessed value by your local tax rate to determine your annual tax.

Example:
A vehicle worth $10,000 in a county with a 5% tax rate:
$10,000 × 33.33% = $3,333.30 (assessed value)
$3,333.30 × 5% = $166.67 (annual tax)

Filing Your Personal Property Declaration

Missouri law requires most personal property owners to file a declaration form annually. This includes details about:

• Vehicles
• Boats
• Business equipment

Deadline: Typically April 1 (stlouis-mo.gov).

Failing to submit a declaration on time can result in a 10% penalty. Most counties provide online filing options to simplify the process.

Payment Methods for Personal Property Tax

Payment can usually be made in three ways:

1. Online: Many counties, including St. Louis City, offer online payment portals (payitstlouis.com).
2. In-Person: At your local county collector office.
3. By Mail: Mail payments to the address listed on your tax bill.

Tip: Always keep a receipt for vehicle registration purposes. Without proof of payment, your registration may not be renewed.

Deadlines and Penalties

• Payment Deadline: December 31 each year (stlouis-mo.gov).
• Late Penalties: Penalties and interest accrue on overdue taxes. Failure to pay can result in blocked vehicle registration and collection actions.

Being proactive and aware of deadlines helps residents avoid unnecessary financial burdens.

Appealing Your Property Assessment

If you feel your property has been overvalued, Missouri allows residents to appeal through:

1. Board of Equalization (BOE): File an appeal typically May 1 to the second Monday in July.
2. Missouri State Tax Commission (STC): If unsatisfied with the BOE decision, appeal to the STC by September 30 or 30 days from BOE decision, whichever is later (stc.mo.gov).

Bring the BOE decision letter, property details, and any supporting documentation. Appealing can reduce your tax liability if the assessment was incorrect.

Special Considerations

• Seniors and Disabled Veterans: Eligible for property tax credits. Contact your county assessor for details.
• New Residents: Moving to Missouri after January 1 typically means no tax liability for that year (cass.missouriassessors.com).
• Business Owners: Must declare all equipment used for business. Failure to do so can result in fines.
