For most W-2 employees, the answer is no: you cannot write off unreimbursed business expenses on your federal tax return. The Tax Cuts and Jobs Act suspended that deduction starting in 2018, and the One, Big, Beautiful Bill Act signed in July 2025 made the suspension permanent by striking its expiration date from the statute.1Congress.gov. H.R.1 – 119th Congress (2025-2026) – Section 70110 A narrow set of specifically designated workers still qualifies. Everyone else has to look to employer reimbursement or state tax rules for any relief.
Before 2018, employees who itemized could deduct unreimbursed job expenses to the extent they exceeded 2% of adjusted gross income. That entire category of miscellaneous itemized deductions was suspended through 2025, and the 2025 law removed the sunset date, so the current statute reads that “no miscellaneous itemized deduction shall be allowed for any taxable year beginning after December 31, 2017,” with no end.2Office of the Law Revision Counsel. 26 U.S. Code 67 – 2-Percent Floor on Miscellaneous Itemized Deductions If a guide you’re reading calls this a temporary suspension, it was written before mid-2025.
For a regular employee in 2026 and beyond, out-of-pocket costs for tools, professional dues, required training, a home office, or work travel produce zero federal tax benefit. It doesn’t matter how necessary the expense was or whether your employer refused to reimburse it.
Employees Who Still Qualify
The permanent suspension carves out five specific groups. These exceptions are written into the tax code itself, not into IRS guidance that could shift. If you fall into one of them, you calculate the deduction on Form 2106 and carry the result to your Form 1040.3IRS. 2025 Instructions for Form 2106 – Employee Business Expenses
Armed Forces Reservists
Reservists who travel more than 100 miles from home and stay overnight for drills or reserve meetings can deduct unreimbursed travel costs as an above-the-line adjustment to income.4Internal Revenue Service. Military Adjustments to Income Workout Above-the-line means it reduces AGI directly and helps you whether you itemize or take the standard deduction. The deductible amount is capped at federal per diem rates for lodging and meals plus the standard mileage rate.
Qualified Performing Artists
Performing artists can deduct work-related expenses above the line, but the qualifying rules are strict. You must meet all three:5Office of the Law Revision Counsel. 26 USC 62 – Adjusted Gross Income Defined
- You performed services in the performing arts as an employee for at least two employers during the year, earning at least $200 from each.
- Your allowable business deductions from performing arts work exceeded 10% of your gross income from that work.
- Your AGI before this deduction was $16,000 or less. Married filers generally must file jointly, and the $16,000 cap applies to combined AGI.
The income ceiling makes this an extremely narrow exception. On a joint return, each spouse must independently meet the first two requirements while the $16,000 cap covers your combined income.6Internal Revenue Service. Publication 463 (2025), Travel, Gift, and Car Expenses
Fee-Basis Government Officials
State or local officials paid in whole or in part on a fee basis can deduct work-related expenses above the line.7Office of the Law Revision Counsel. 26 USC 62 – Adjusted Gross Income Defined This generally covers officials such as justices of the peace, notaries, or county clerks whose compensation comes from fees rather than salary.
Employees With Impairment-Related Work Expenses
If you have a physical or mental disability and pay for attendant care at work or other impairment-related expenses needed to do your job, those costs remain deductible. The statute specifically exempts impairment-related work expenses from the miscellaneous itemized deduction suspension.8Office of the Law Revision Counsel. 26 USC 67 – 2-Percent Floor on Miscellaneous Itemized Deductions
Statutory Employees
Statutory employees get overlooked constantly. Check Box 13 of your W-2: if the “Statutory employee” box is marked, you report income and expenses on Schedule C, not through the miscellaneous itemized deduction rules at all.9Internal Revenue Service. Statutory Employees That means you deduct ordinary and necessary business expenses directly against your income, the way a self-employed person does. Four categories qualify:
- Agent or commission drivers who distribute beverages (other than milk), meat, produce, or bakery products, or who pick up and deliver laundry or dry cleaning.
- Full-time life insurance salespeople whose principal business is selling life insurance or annuity contracts, primarily for one company.
- Home workers who work on materials the employer supplies, following employer specifications, and return the finished work.
- Full-time traveling salespeople who turn in orders from wholesalers, retailers, or similar businesses as their principal business activity.
Business expenses go on Schedule C, not Form 2106.10Internal Revenue Service. Instructions for Schedule C (Form 1040) (2025) Social Security and Medicare taxes are already withheld, so no self-employment tax is owed on this income.
What Changed for Educators in 2026
K-12 educators have long had a separate above-the-line deduction for classroom supplies, and that still exists at up to $300 per qualifying educator for 2026.11Internal Revenue Service. Topic No. 458, Educator Expense Deduction The 2025 law added a second layer starting with the 2026 tax year: a separate itemized deduction for educator expenses that has no 2% AGI floor and no dollar cap.1Congress.gov. H.R.1 – 119th Congress (2025-2026) – Section 70110
An educator who spends $2,000 on supplies and itemizes can claim the full amount on Schedule A on top of whatever they take above the line. The law also broadened who counts: interscholastic sports coaches and administrators are now eligible educators, supplies no longer need to be non-athletic, and “instructional activity” replaces the narrower “in the classroom” test. The trade-off is that this expanded deduction only helps educators who itemize; those who take the standard deduction still get only the $300 above-the-line amount.
Employer Reimbursement Is the Realistic Path
With the employee deduction gone for most workers, reimbursement from your employer is the only tax-advantaged way to recover job-related costs. The tax treatment depends entirely on whether your employer’s plan qualifies as an accountable plan.
Accountable Plans
Reimbursements under an accountable plan are tax-free. They don’t show up in your taxable wages, aren’t subject to income tax withholding or payroll taxes, and don’t appear in Box 1 of your W-2. The plan must meet three requirements:12Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide
- Business connection: the expense must be one you paid while performing services as an employee, and the reimbursement must be for that expense rather than disguised wages.
- Substantiation: you must document each expense to your employer with the amount, date, location, and business purpose. The IRS treats 60 days after payment as a reasonable window.
- Return of excess: if the employer advanced or reimbursed more than you substantiated, you must return the excess. The IRS treats 120 days as reasonable for returning overpayments.
If a policy fails even one of these, it’s a non-accountable plan. Any amount that isn’t substantiated or returned gets reclassified as taxable wages for the first payroll period after the deadline passes.
Non-Accountable Plans
Payments under a non-accountable plan are simply added to your taxable wages. Your employer includes them in Box 1 and withholds income and payroll taxes on the full amount. You cannot deduct the underlying expense to offset that income, because the deduction doesn’t exist. You end up paying tax on money that was supposed to cover a work cost. If your employer offers reimbursement, it’s worth confirming the plan actually meets the accountable plan standards.
Mileage
Business use of a personal vehicle is one of the most common reimbursable expenses. The IRS standard mileage rate for 2026 is 72.5 cents per mile for business travel.13IRS. Standard Mileage Rates Employers on accountable plans often reimburse at or near this rate. If yours pays less, the shortfall is out of pocket and not deductible. If yours pays more, you have to return the excess or the overage becomes taxable wages.
Commuting Never Counts
Even back when the deduction existed, commuting was never part of it. Driving from home to your regular workplace is a personal expense no matter the distance and no matter what you’re doing during the trip.6Internal Revenue Service. Publication 463 (2025), Travel, Gift, and Car Expenses
Travel between workplaces is different. Going from one work location to another during the same day is deductible transportation. So is the round trip from home to a temporary job site when you also have a regular work location, regardless of distance. The line the IRS looks at is whether you’re heading to your regular place of work or somewhere else.
What Happens If You Claim It Anyway
Some taxpayers still try to deduct unreimbursed employee expenses, either following older advice or using aggressive software. The IRS has automated filters that flag Form 2106 filed by employees outside the exempt categories. Claiming miscellaneous itemized deductions you’re not entitled to can trigger an accuracy-related penalty of 20% of the resulting underpayment, on top of the tax owed plus interest.14Internal Revenue Service. Accuracy-Related Penalty The penalty covers underpayments caused by negligence or disregard of the rules.
Your State Return May Be Different
The permanent federal suspension does not control your state income tax return. Several states never adopted the TCJA changes to miscellaneous itemized deductions, and their tax codes still follow the pre-2018 federal rules. In those states, you may be able to deduct unreimbursed employee business expenses as an itemized deduction subject to the older 2% AGI floor. Which states conform shifts as legislatures update their codes, so check your state’s current instructions. Where the deduction survives, you’ll generally use the same expense categories and substantiation rules that applied under the old federal system, which makes keeping receipts and mileage logs worthwhile even if your federal return doesn’t use them.
