Education Freedom Scholarships and Opportunity Act This bill allows individual and corporate taxpayers a tax credit for cash contributions to tax-exempt scholarship-granting organizations for elementary and secondary education expenses. It imposes a cap of $5 billion on the amount of contributions that qualify for a tax credit. The bill directs the Department of Education, in coordination with the Department of the Treasury, to establish, host, and maintain a web portal that (1) lists all eligible scholarship-granting organizations; (2) enables contributions to such organizations; (3) provides information about the benefits of this bill; and (4) enables a state to submit and update information about its programs and scholarship-granting organizations, including information on student eligibility and allowable educational expenses.
