Educator Expense Deduction Calculator

Teachers and other school staff routinely spend their own money on supplies the district never reimburses, and the tax code carves out a narrow break to recognize that. For the 2026 tax year, an eligible educator can subtract up to $350 of those out-of-pocket costs from income. When two educators are married and file a joint return, the household ceiling rises to $700, though neither spouse may claim more than $350 of their individual spending.

Arriving at the figure is a matter of comparison rather than complex math. Add up every qualified, unreimbursed dollar you spent on classroom materials and professional development, then measure that total against the cap tied to your filing status. Single filers and those married filing separately are limited to $350, while joint filers who are both educators share the $700 limit, up to $350 each. Whichever number is smaller, your actual spending or the statutory cap, becomes your deduction.

Documentation is what protects the deduction if questions ever arise, so hold on to receipts and note what each purchase was and the date you made it. Costs that have no clear tie to instruction or professional development should be left off entirely, since they are a frequent source of error. One feature works in your favor regardless of how you file: this is an above-the-line deduction, so it lowers your adjusted gross income whether you itemize or claim the standard deduction. Starting with 2026 returns, unreimbursed classroom spending above the cap is no longer lost if you itemize: the One Big Beautiful Bill Act lets it be claimed as an itemized deduction, which is why the calculator shows any excess separately.
