The educator expense deduction for teachers

By Tom, CPA · Updated October 27, 2026

Part of: Easy Tax Strategies

TL;DR: Eligible K-12 educators can deduct up to $350 of unreimbursed classroom expenses for 2026 ($700 for two educators filing jointly, $350 each), without itemizing. You must work at least 900 hours a school year in a K-12 school. Starting in 2026, the 2025 tax law also lets educators who itemize deduct unreimbursed expenses beyond the cap.

Educational only, not tax, legal, or investment advice. Examples are illustrations, not predictions. Rules and limits change; verify current figures and talk to a qualified professional about your situation.

Teachers routinely buy pencils, paper, books, tissues, snacks, and sometimes an entire classroom library out of pocket. The tax code's acknowledgment of this is the educator expense deduction, which is generous in spirit and small in size: $350 for 2026. It is still worth claiming every year, and the 2025 tax law added a second layer for teachers who itemize.

CPA Warning Label: Expenses reimbursed by your school, a grant or a crowdfunding campaign are not deductible, and you cannot double count the same expense above and below the line.

Amount

The amount is indexed for inflation in $50 steps, so it moves slowly. It is an adjustment to income on Schedule 1, so it lowers AGI and applies whether you itemize or not. At a 12% bracket, $350 saves $42; at 22%, $77. Not life-changing, but it is money you already spent.

Who qualifies

An eligible educator is a kindergarten through grade 12 teacher, instructor, counselor, principal or aide who works at least 900 hours during a school year in a school that provides elementary or secondary education under state law. Public, private and religious schools count. Not covered by the above-the-line deduction:

• Homeschooling parents.
• College and university faculty.
• Preschool teachers, unless the program is part of an elementary school under state law.
• Substitutes and part-timers below 900 hours.

Eligible items

Unreimbursed costs for:

• Books, supplies and other classroom materials.
• Computer equipment, software and online services used in the classroom.
• Athletic supplies for physical education and health courses.
• Personal protective equipment and supplies to prevent the spread of disease in the classroom, such as masks, sanitizer and air purifiers.
• Professional development courses related to the curriculum or students you teach.

Not eligible: homeschooling costs, nonathletic supplies for health or physical education courses, and anything reimbursed. Snacks for students fall in a gray area; the IRS lists supplies used in the classroom, so food is safer to leave out unless clearly instructional.

Itemized expansion

Before 2018, teachers could deduct expenses beyond the above-the-line cap as miscellaneous itemized deductions subject to a 2% of AGI floor. The 2017 law suspended those deductions; the 2025 law made that suspension permanent but carved out an exception: starting in 2026, unreimbursed expenses of eligible educators are allowed as an itemized deduction, without the 2% floor. Per IRS guidance on the new law, the definition for this itemized deduction also covers certain interscholastic sports administrators and coaches.

How the two layers interact:

1. Take the first $350 above the line.
2. If you itemize, deduct the remaining qualified expenses as an itemized deduction.
3. If you take the standard deduction, the excess gets no benefit.

Since most teachers take the standard deduction, the itemized layer helps mostly homeowners in high-tax areas or those with large mortgages. See itemized vs. standard.

Example

Illustration: Frugal Fran and her spouse are both K-12 teachers, filing jointly for 2026. Fran spent $520 on books and supplies; her spouse spent $210 on software and a professional development course. Neither was reimbursed. They take the standard deduction.

Note that Fran's unused $170 cannot shift to her spouse; each is capped at $350. At a 12% bracket, $560 saves $67.20. If they itemized, Fran's extra $170 could be an itemized deduction. Lavish Larry, a parent volunteer who bought the class a smart board, gets no deduction at all; he is not an eligible educator, but he did get a very nice thank-you card.

Records

• Receipts showing date, vendor, item and amount.
• A short note on how each item was used in the classroom.
• Records of any reimbursement, grants or crowdfunding (for example, classroom-funding sites) for the same items.
• Proof of employment and hours if questioned, such as a contract.

A simple habit: photograph receipts and keep them in one folder or a phone album labeled by school year. Keep them at least three years after filing.

Reimbursements and grants

Deductible expenses are reduced by reimbursements from your school, PTA or grants not reported as income. Some educators also have to reduce eligible expenses by certain tax-free education savings amounts, such as interest excluded on Series EE or I bonds redeemed for education or tax-free 529 or Coverdell distributions in the same year. Crowdfunded supplies that were bought for you directly are not your expense at all.

How to claim it

In tax software, look for "educator expenses" in the deductions or adjustments section; it lands on Schedule 1 of Form 1040. If you are married filing jointly and both are educators, enter each person's expenses separately so the software applies the $350 per-person cap correctly. If you itemize for 2026, check that the software carries any excess to Schedule A; because the itemized layer is new, early versions of some programs may need you to enter it manually. Nothing is attached to the return; you just keep the receipts.

Second example: itemizing teacher

Illustration: A single high school science teacher in a high-tax state itemizes for 2026 because mortgage interest and state taxes exceed the $16,100 standard deduction. She spends $1,400 on lab supplies and a curriculum-related course, with no reimbursement.

• Above the line: $350.
• Itemized on Schedule A: $1,400 − $350 = $1,050.
• Total deducted: $1,400.
• At a 22% bracket: about $308 of federal tax saved, versus $77 under the pre-2026 rules.

If she were close to the standard deduction line, comparing both each year matters, since the itemized layer only helps when she itemizes.

Common mistakes

• Claiming reimbursed items, including items bought with a school-issued card.
• Combining spouses' caps. Each eligible educator is limited to $350; a non-educator spouse's spending does not count.
• Double dipping the same expense above the line and on Schedule A.
• Counting non-classroom items, such as clothing for work or commuting.
• Forgetting professional development, which many teachers pay for themselves.
• Ignoring state rules. Some states offer their own educator deduction or credit; others do not follow the federal itemized change.

Medical-style records discipline helps here too; the same receipt habits apply to the medical expense deduction.

Planning tips

• Buy supplies for the next school year in the same tax year as needed to reach the cap, but do not spend just to deduct; you spend $1 to save 12 to 22 cents.
• Ask about school supply budgets first; reimbursed money is better than any deduction.
• If you itemize, track every eligible expense; the 2026 change makes them all count.
• Use cash-back on supply purchases; see the low-cost focus of why expense ratios matter, which applies to classroom budgets too, and the expense ratio fee calculator for your retirement funds.

Retirement savings for teachers

A bigger tax lever than classroom receipts: many teachers have access to both a 403(b) and a governmental 457(b), each with its own $24,500 deferral limit for 2026. Deferring into both can cut taxable income far more than $350 ever will. Check the fund fees in those plans; high-cost 403(b) annuities are common, and fees compound against you.

Where to get help

IRS Topic 458 on irs.gov covers the educator expense deduction, and Free File or VITA sites can help teachers with simple returns at no cost.

Bottom line

Claim the $350 every year; it takes a minute. If you itemize, the 2026 change finally lets the rest of your classroom spending count. Keep receipts, subtract reimbursements, and never spend extra just for the deduction.
