The Bottom Line

Missouri's April Board of Equalization meetings create a pressure-cooker environment. With assessment notices often arriving just days before BOE meetings begin, preparation is everything.

The biennial assessment cycle means missing April 2026 costs you two full years of overpayment. Whether you're fighting St. Louis urban transitions or Kansas City border effects, April is your only realistic shot.

Each county's unique schedule within April requires vigilance. Mark your county's dates now and prepare evidence in advance - when that notice arrives, you'll need to move fast.

Critical Note: Missouri counties hold Board of Equalization meetings throughout April, but specific dates vary significantly. Some counties meet for just 3-5 days, others for several weeks. Many require appointments made well in advance. Contact your county assessor NOW to get exact 2026 dates and requirements. Missing April means waiting until 2027.
