Enacts the "educator expense assistance act"

This bill creates a new tax deduction for K-12 educators. Eligible educators (those teaching at least 900 hours per year in public or private elementary/secondary schools) can deduct up to $300 annually as a single filer or $600 as a married couple filing jointly (with each spouse limited to $300). The deduction covers out-of-pocket work-related expenses like professional development courses, books, supplies, computer equipment, and supplementary materials (athletic supplies are specified for health/physical education courses). It amends tax law to add this provision, effective immediately upon enactment.
