For most W-2 workers, unreimbursed employee business expenses are not deductible on a federal tax return. The Tax Cuts and Jobs Act suspended the miscellaneous itemized deduction that used to cover these costs starting in 2018, and the One Big Beautiful Bill Act signed in 2025 removed the sunset date, so the suspension has no scheduled end. A few narrow occupational categories can still deduct, and some states allow the write-off on their own returns even though the federal one is gone.
Why the Federal Deduction Is Gone
Before 2018, employees could deduct unreimbursed work costs as a miscellaneous itemized deduction, but only the portion above 2% of adjusted gross income. The Tax Cuts and Jobs Act eliminated that entire category. The original suspension was scheduled to expire on January 1, 2026, which would have restored the old rule. That didn’t happen. Congress struck the expiration language in 2025, and 26 U.S.C. § 67(h) now reads that no miscellaneous itemized deduction is allowed for any tax year beginning after December 31, 2017, with no end date.1Office of the Law Revision Counsel. 26 USC 67 – 2-Percent Floor on Miscellaneous Itemized Deductions
The practical result: professional dues, work tools, mandatory uniforms, home office supplies, and job-related travel provide zero federal tax benefit for typical salaried and hourly workers. Even if your employer requires the expense as a condition of the job, it doesn’t matter for federal purposes.
Who Can Still Deduct on a Federal Return
Four categories of employees escaped the suspension. Their unreimbursed business expenses are treated as above-the-line deductions under 26 U.S.C. § 62(a)(2), reducing adjusted gross income directly.2Office of the Law Revision Counsel. 26 USC 62 – Adjusted Gross Income Defined
- Armed Forces reservists who travel more than 100 miles from home for service can deduct unreimbursed travel expenses, capped at the federal per diem rate.3Internal Revenue Service. Publication 3 – Armed Forces Tax Guide
- Qualified performing artists, but the rules are tight: at least two performing arts employers during the year, deductible expenses over 10% of gross performance income, and adjusted gross income no higher than $16,000. That income cap has never been indexed for inflation, which effectively limits the deduction to part-time or entry-level performers.2Office of the Law Revision Counsel. 26 USC 62 – Adjusted Gross Income Defined
- Fee-basis state or local government officials, meaning government employees paid at least partly by fees rather than a set salary.
- Employees with impairment-related work expenses. A worker with a physical or mental disability that limits their ability to work can deduct expenses necessary to perform the job, such as attendant care at the workplace or adaptive equipment. The expenses must be necessary for work and not primarily personal.4Internal Revenue Service. Publication 907 – Tax Highlights for Persons With Disabilities
All four groups file Form 2106 to calculate the deductible amount, which then feeds onto Schedule 1.5Internal Revenue Service. Instructions for Form 2106 If you don’t fit one of these categories, you cannot use Form 2106 at all. Filing it without qualifying is a fast route to an adjustment.
The Educator Expense Deduction
K–12 school employees have a separate, smaller write-off. Eligible educators can deduct up to $300 per year for unreimbursed classroom supplies, books, computer equipment, and professional development. If both spouses are eligible educators filing jointly, the joint cap is $600, but neither spouse can exceed $300 individually.6Internal Revenue Service. Topic No. 458 – Educator Expense Deduction
To qualify, you must be a teacher, instructor, counselor, principal, or aide who works at least 900 hours during a school year at a school providing elementary or secondary education under state law.6Internal Revenue Service. Topic No. 458 – Educator Expense Deduction This is above-the-line, so you get it whether or not you itemize. It’s claimed directly on Schedule 1 without Form 2106.7Internal Revenue Service. Publication 529 – Miscellaneous Deductions
Statutory Employees
Some W-2 workers are classified as statutory employees, with the box in Box 13 of the W-2 checked. They report their income and deduct their business expenses on Schedule C rather than through the suspended miscellaneous deduction, so the suspension does not affect them.8Internal Revenue Service. Statutory Employees
The IRS recognizes four types:
- Commission or agent delivery drivers distributing beverages, food products, or laundry and dry cleaning.
- Full-time life insurance salespeople whose primary work is selling life insurance or annuity contracts for one company.
- Home workers who work on materials supplied by an employer and follow the employer’s specifications.
- Full-time traveling salespeople collecting orders from wholesalers, retailers, or similar businesses on behalf of a single company.
If Box 13 on your W-2 shows statutory employee, your business expenses go on Schedule C and offset that income directly. Federal income tax typically isn’t withheld from statutory employee wages, so tax planning has to account for that.8Internal Revenue Service. Statutory Employees
Self-Employed and Independent Contractors Are Not Affected
The suspension applies only to employees. If you’re self-employed or working as an independent contractor, your ordinary and necessary business expenses remain fully deductible on Schedule C. Someone who leaves a salaried role and starts freelancing often doesn’t realize that the same software, home office, and equipment costs their old employer refused to reimburse now qualify as business expenses against self-employment income.
This produces a real tax gap between employees and contractors doing similar work. A freelance graphic designer deducts their software subscriptions and equipment; a salaried designer at an agency buying the same items out of pocket gets nothing on their federal return.
State Returns May Still Allow the Deduction
Several states did not follow the federal government in eliminating this deduction. Workers in those states can still claim unreimbursed employee expenses on their state income tax returns. The rules vary. Some states apply a 2% adjusted gross income floor that mirrors the old federal rule, so only expenses above that threshold count. Others allow the full amount without a percentage limit.
The categories of allowed expenses differ too. Union dues might be fully deductible in one state and treated differently in another. If you live in a state with an income tax and you’re spending significant money on unreimbursed work costs, check your state’s individual income tax instructions. The deduction won’t appear on the federal return, but it can still cut your state tax bill.
Getting Reimbursed by Your Employer
The better outcome, before any deduction question, is being paid back. No federal law requires employers to reimburse employees for business expenses, but roughly a dozen states have enacted their own reimbursement mandates. These state laws generally require employers to cover expenses that are necessary and incurred as a direct consequence of performing job duties. If you work in one of those states and your employer isn’t reimbursing required costs, that can be pursued as a wage claim.
How reimbursement is structured also affects your taxes. Under an accountable plan, the reimbursement is not taxable wages. Three requirements must be met: the expense must have a clear business connection, you must substantiate it to your employer with receipts or documentation within 60 days, and you must return any excess reimbursement you didn’t spend. Most large employers run accountable plans, which is why expense reports have deadlines and receipt rules.
If any one of those three requirements fails, the arrangement is a non-accountable plan. The reimbursement gets included in your taxable wages on your W-2, and you owe income and payroll tax on it. Before 2018, you could at least offset that with a miscellaneous itemized deduction. With the suspension permanent, employees under non-accountable plans are effectively taxed on their own work expenses. A flat monthly stipend with no receipts and no return of excess is a non-accountable arrangement, and the full amount is taxable.
If You Claim the Deduction Anyway
Some taxpayers still file returns claiming unreimbursed employee expenses, whether from outdated advice or old entries carried forward by tax software. The IRS notices. When an improper deduction produces a significant underpayment, the accuracy-related penalty under 26 U.S.C. § 6662 is 20% of the underpaid tax.9Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty The penalty applies when the underpayment results from negligence or a substantial understatement of income tax, which for individuals means understating tax by the greater of 10% of what’s actually owed or $5,000.10Internal Revenue Service. Accuracy-Related Penalty
Interest also runs from the original due date of the return, and the IRS cannot waive interest even where it reduces the underlying penalty. Back taxes, the 20% penalty, and compounding interest can turn a modest improper deduction into a costly error. If you claimed these deductions in prior years and haven’t reviewed your filings since the law changed, confirm your preparer or software isn’t carrying forward entries that no longer apply.
