Missouri Closing-Date Prorations: Property Tax and Insurance Math

Under Missouri law, the seller is responsible for all real property taxes for the year of closing, with no proration of taxes to the buyer. This rule, found in Mo. Rev. Stat. § 139.100, assigns 0% of the annual tax liability to the buyer at closing. The statute effectively treats the seller as the sole taxpayer for the entire calendar year in which the sale occurs. The buyer assumes liability only for taxes assessed after the closing date, beginning with the next tax year. The worked example below demonstrates how this allocation functions in practice. For an estimate tailored to a specific closing date and tax amount, use the calculator linked to the official source.
