Exemptions & appeals
Exemption filing
No general Missouri homestead exemption was verified. 2026 personal-property assessment lists are generally due March 1, 2026; late filing can incur the statutory penalty.
Senior relief
Johnson County Senior Real Estate Tax Credit under Ordinance 25-01: eligible homeowners must be Johnson County residents, age 62 or older before January 1, 2026, owner of record and liable for taxes, physically occupy the property as their primary residence, and have paid prior-year property taxes. Applications or renewals for 2026 were due June 30, 2026.
Valuation limits
No general local annual valuation cap was verified. Johnson County’s senior program credits eligible primary-residence tax liability rather than capping market or assessed value. Missouri real property is generally reassessed in odd-numbered years; statutory assessment ratios are 19% residential, 32% commercial, and 12% agricultural.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
