MO HB3164

Requires the Missouri State Tax Commission to use ratio studies when determining whether property classes are valued below or above true market value for equalization purposes

Property is considered undervalued if the weighted median ratio is less than 70% combined with either a coefficient of dispersion greater than 25% or the upper bound of the 95% confidence interval is less than 70%

Property is considered overvalued if the weighted median ratio exceeds 100% combined with either a coefficient of dispersion greater than 25% or the upper bound of the 95% confidence interval exceeds 100%

Amends Section 138.390, RSMo, which governs how the commission equalizes real and tangible personal property valuations across Missouri counties
