Supporting Teachers Through Tax Fairness Act

This bill creates a tax exclusion for K-12 public school teachers, allowing them to exclude up to $50,000 of their wages from federal income tax. Teachers in schools where 75%+ students qualify for free/reduced lunches, in rural areas, or teaching special education/STEM subjects qualify for a higher exclusion of $65,000. To qualify, teachers must work at least 900 hours in a school year at a public elementary or secondary school (including charter schools). The exclusion applies to taxable years beginning after December 31, 2025, and requires schools to verify eligibility for the IRS. It directly affects eligible K-12 public school teachers by reducing their taxable income.
