Creates, repeals, and modifies provisions governing elementary and secondary education

HB 2866 establishes Missouri's Empowerment Scholarship Accounts Program, which provides tax credits to Missouri taxpayers who donate to qualifying charitable organizations that fund education scholarships. Taxpayers can claim a credit equal to 100% of their contribution (capped at 50% of their state tax liability), with a total annual spending limit of $150 million adjusted yearly based on school funding. The program directs scholarship funds to eligible students through educational assistance organizations, limiting certified organizations to 15 per year and allocating tax credits on a first-come, first-served basis. It directly affects taxpayers making donations, charitable organizations administering scholarships, and families seeking education options beyond traditional public schools.
