Substitute teachers tax write-offs

Varies

What Can Substitute teachers Write Off?

Short answer: Subs who log 900 school hours a year qualify for the $300 educator deduction; otherwise classroom costs aren't federally deductible.

K-12 educators with 900+ school hours deduct up to $300 above the line; from 2026 costs beyond that can be itemized, while other W-2 job costs stay nondeductible.

Records to keep: Keep receipts, 1099s or W-2s, a mileage log, and a note of the business purpose for each expense.
