Exemptions & appeals

Senior relief

Adair County Ordinance 2026-1 SB-190 senior property-tax credit: Missouri resident, age 62 or older, owner/liable taxpayer occupying the primary residence; the credit freezes the home's tax at the 2025 assessment level, requires annual application, and applications are accepted April 1–June 30, 2026.

Valuation limits

No general local annual valuation cap was verified. Missouri real property is generally reassessed in odd-numbered years, with statutory assessment ratios (19% residential, 12% agricultural, 32% commercial); any local senior credit limits tax liability rather than market or assessed value.

For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
