Do I qualify for the Educator Expense Deduction?
Full-time teachers, instructors, counselors, principals, or aides in kindergarten through 12th grade who work 900 hours during a school year can deduct up to $300 for their out-of-pocket costs. This applies to professional development courses related to the curriculum or students they teach as well as supplies, books, equipment, and supplementary materials used in their classroom.
Keep in mind that qualified expenses don't include expenses for homeschooling or non-athletic supplies for health or physical education courses. Also, don't include any expenses that were reimbursed.
