Enacts the "educator expense assistance act"

This bill creates a new tax deduction for K-12 educators, allowing them to deduct up to $300 annually (or $600 for married couples filing jointly, with $300 each) for unreimbursed work-related expenses. It directly affects teachers, counselors, principals, and aides who worked at least 900 hours during a school year. Eligible expenses include professional development, books, supplies, computer equipment, and supplementary materials (with specific rules for health/physical education supplies). The deduction is added to the tax code as a concrete policy change, effective immediately upon enactment.
