The educator expense deduction lets K-12 teachers, instructors, counselors, principals, and aides who work at least 900 hours in a school year subtract up to $300 of unreimbursed classroom expenses directly on their tax return — no itemizing required. It is an "above-the-line" adjustment to income (Form 1040, Schedule 1), so it helps even if you take the standard deduction.
Non-athletic supplies for health or PE courses historically did not qualify; home schooling costs and expenses that were reimbursed by the school do not count. You cannot double-dip — expenses used for this deduction cannot also be claimed as a business expense or charity.
The limit is $300 per educator ($600 if married filing jointly and both spouses are eligible educators, but not more than $300 each). You must claim the deduction on Schedule 1, line 11. Keep receipts — the IRS can ask for them.
⚠️ Important: This calculator applies the 2025 $300 per-educator limit and estimates tax savings at your chosen marginal rate. It is an educational estimate and not tax advice. Confirm your eligibility and the exact limit for your tax year using IRS Topic No. 458 and the Schedule 1 instructions.
