Quick summary
Unreimbursed employee expenses are costs you incur performing your job that your employer doesn’t reimburse. The Tax Cuts and Jobs Act (TCJA) suspended miscellaneous itemized deductions subject to the 2% of AGI floor — which historically included many unreimbursed employee expenses — for tax years 2018 through 2025. That means most W-2 employees can’t deduct these costs on their federal returns. A handful of statutory exceptions still permit deductions or special treatment; classroom educators, certain reservists, qualified performing artists, fee-basis state or local government officials, and employees with impairment-related work expenses may qualify under narrow rules. Check the IRS for current dollar limits and details (see IRS publications and guidance below).
(For a focused discussion of education-specific rules, see this internal guide on Educator Expenses Deduction and for context on above-the-line options, see Above-the-Line Deductions You Might Be Missing.)
Background: How we got here
Before the TCJA (Tax Cuts and Jobs Act of 2017), many employees who itemized could deduct unreimbursed employee business expenses as miscellaneous itemized deductions on Schedule A once total miscellaneous deductions exceeded 2% of adjusted gross income (AGI). Common examples were uniforms, tools, union dues, job-related travel and continuing education.
TCJA changed the rules by suspending miscellaneous itemized deductions that were subject to the 2% floor for most taxpayers for tax years 2018 through 2025. Practically, that eliminated the federal tax benefit for most unreimbursed employee expenses during that period. The law did not, however, repeal all deductions for every type of worker; Congress preserved a limited set of statutory exceptions.
Primary IRS references: see IRS Publication 463 (travel, gift, and car expenses) and the IRS pages on educator expenses and employee business expenses for authoritative explanations. Always confirm current-year limits and instructions on IRS.gov.
Who still qualifies for deductions or special treatment?
The list of exceptions is narrow and contains specific eligibility rules. The main categories frequently mentioned are:
-
Qualified educators: Elementary and secondary school teachers and certain other educators may claim an adjustment to income for qualifying out-of-pocket classroom expenses (check the current-year limit and rules on IRS.gov). This is an above-the-line deduction, so you can claim it even if you don’t itemize. See FinHelp’s article: Educator Expenses Deduction.
-
Members of the reserve components of the U.S. Armed Forces: Some reservists who travel more than a statutory distance and meet other criteria may still deduct unreimbursed travel and related expenses.
-
Qualified performing artists: Under IRC rules, performers who meet income thresholds, have employer withholding, and meet other tests may still qualify to deduct certain unreimbursed business expenses.
-
Fee-basis state or local government officials: Officials compensated on a fee basis (rather than a salary) have a statutory exception allowing deduction of certain expenses.
-
Employees with impairment-related work expenses: Employees whose job requires special equipment or services because of a physical or mental disability can deduct impairment-related work expenses in certain circumstances.
Exact eligibility, thresholds, and how you report these expenses vary by group. If you think you fall into one of these categories, review the IRS instructions carefully and retain documentation. For detailed rules on travel, vehicle, and meal expense substantiation see IRS Publication 463.
How the rules affect common occupations
-
Classroom teachers: If you buy supplies, decorations or small teaching aids, part (or all) of your out-of-pocket cost may be deductible under the educator deduction or other rules if you meet the statutory tests. Keep receipts and document how items were used in the classroom. See FinHelp’s Educator Expenses Deduction for more on common documentation questions.
-
Office employees, retail workers, non-performing W-2 employees: For the vast majority of regular employees who receive a W-2, out-of-pocket expenses for job-required clothing, mileage to a second job, or tools are not deductible during the TCJA suspension unless an employer’s policy or a specific statutory exception applies.
-
Self-employed or 1099 contractors: Not employees — independent contractors continue to deduct ordinary and necessary business expenses on Schedule C, including mileage, software, supplies and home office costs (subject to the usual rules and substantiation). If you have a mix of self-employment and employment income, keep expense categories clearly separated.
How to claim (forms and where to report)
-
Educator adjustment: Typically taken as an above-the-line adjustment on Schedule 1 (Form 1040) — check the current-year Form 1040 instructions for the correct line and limits.
-
Exceptions (reservists, performing artists, etc.): Historically, some of these taxpayers used Form 2106 (Employee Business Expenses) and then Schedule A to report unreimbursed employee expenses. The exact reporting channel depends on whether the exception permits an itemized deduction or an adjustment. Refer to the IRS instructions for the current tax year and Publication 463 for specifics.
-
Self-employed: Report on Schedule C (Form 1040) and claim the business expenses against self-employment income. Self-employed taxpayers also deduct the self-employment tax deduction on Schedule 1.
Important: Because tax forms and line numbers change, always use the latest IRS instructions for the year you’re filing.
Practical strategies — reduce out-of-pocket exposure and protect tax outcomes
-
Ask your employer for an accountable reimbursement plan. Under an accountable plan, employers reimburse business expenses without reporting the amounts as wages, and reimbursements are not taxable to you. Encourage employers to adopt clear reimbursement policies and simple submission procedures.
-
Keep excellent records. For any expense that might be reimbursable or deductible under an exception, keep dated receipts, descriptions of the business purpose, mileage logs (with date, mileage in/out and purpose), and employer correspondence denying reimbursement if applicable.
-
Separate employee vs. self-employed activities. If you do freelance work in addition to a W-2 job, place income and expenses for your self-employment on Schedule C. Don’t mix employer-required expenses with your self-employment records.
-
Use available employer benefits. Flexible spending accounts (FSAs), transportation benefits, employer-provided equipment or education assistance can reduce your after-tax costs.
-
Consider the tax math. For example, a $1,200 educator expense out-of-pocket with a hypothetical available deduction of $300 yields an immediate tax saving only on that $300 times your marginal rate — the rest remains an unreimbursed personal cost. Running the numbers with a tax pro can show the practical value of pursuing reimbursements vs. spending out of pocket.
-
If denied reimbursement, escalate thoughtfully. Present purchase records and the job connection to your manager or HR. If you represent a union or professional association, check collective bargains or member benefits that could cover costs.
Recordkeeping checklist
- Itemized receipts and invoices
- Credit card or bank statements matching purchases
- Mileage logs (date, starting and ending odometer, business purpose)
- Employer communications (reimbursement policy, approval/denial email)
- Documentation showing how supplies were used (photos, lesson plans, client invoices)
Good records reduce audit risk and make it easier to claim any permitted deduction or to defend reimbursements.
Common misconceptions
-
“If I buy it for work, I can deduct it.” Not anymore for most W-2 employees. The TCJA suspension removes this for many taxpayers.
-
“I can always claim travel and mileage as an employee.” Only if you meet a statutory exception or if you’re self-employed. Otherwise, employee travel expenses are generally non-deductible for the years the TCJA suspension is in effect.
-
“There’s no point in tracking expenses.” Wrong — tracking is still critical. Records are needed to pursue reimbursements, to support any statutory exception, and to separate self-employment activity.
Example (illustrative, hypothetical)
Jane, an elementary teacher, spends $1,200 on classroom supplies in a year. Suppose the current-year educator adjustment allows a portion of those expenses to be deducted (verify the limit on IRS.gov). If she qualifies to claim $300 as an above-the-line deduction and she’s in the 22% marginal tax bracket, the immediate federal income tax saving would be roughly $66 (0.22 × $300). The remaining $900 would not reduce her federal income taxes unless reimbursed by her district or covered by another rule.
This illustration is hypothetical — actual tax impact varies with your filing status, other deductions, and marginal tax rate.
Next steps
- Confirm current-year limits and filing instructions on IRS.gov (see IRS Publication 463 and the IRS educator webpage).
- If you’re an employee, review your employer’s reimbursement policy and ask whether an accountable plan can be used.
- If you believe you qualify for an exception, keep documentation and consult a CPA or tax advisor before filing.
