Employee expenses are the out-of-pocket costs you pay while doing your job: mileage between job sites, tools your employer expects you to own, a required uniform, a professional license renewal. Since the Tax Cuts and Jobs Act took effect in 2017, most W-2 workers have not been able to deduct these costs on a federal return, and a law signed on July 4, 2025 made that restriction permanent.1Office of the Law Revision Counsel. 26 USC 67 – 2-Percent Floor on Miscellaneous Itemized Deductions For almost everyone on a W-2, the realistic way to recover job costs is an employer reimbursement, and the way that reimbursement is set up decides whether it lands in your bank account tax-free or gets taxed as wages.
The Ordinary and Necessary Test
Every expense that qualifies as a business cost has to clear the same two-word standard in federal tax law: it must be both ordinary and necessary.2Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses Ordinary means people in your line of work commonly incur the cost. Necessary means the cost is helpful and appropriate for getting the job done, not that it is absolutely essential. The expense also has to connect to your employer’s business rather than your personal preferences.3eCFR. 26 CFR 1.162-1 – Business Expenses A graphic designer buying a font license clears the bar. The same designer buying a surfboard does not, even with a story about creativity.
What Counts as a Job Expense
Travel and Mileage
Business travel covers driving between work sites, visiting clients, airfare and hotels for out-of-town assignments, and incidentals like parking and tolls.4Internal Revenue Service. Publication 463 (2025), Travel, Gift, and Car Expenses The IRS standard mileage rate for business driving in 2026 is 72.5 cents per mile.5Internal Revenue Service. 2026 Standard Mileage Rates Travel between two workplaces in the same day is always a business expense, even when the jobs are for different employers.
Your daily commute is not. Driving from home to your regular office is a personal cost, period. The wrinkle is temporary assignments. If your employer sends you to a job site expected to last one year or less, the IRS treats that location as temporary and the drive counts as business travel regardless of distance. Once an assignment is expected to run longer than a year, the site becomes your new tax home, and the drive turns back into a nondeductible commute. Construction workers, consultants, and traveling nurses rotating through long assignments get tripped up here more than anyone.
Business Meals
Meals qualify when you eat with a client or business contact for a clear business purpose, or when you are traveling away from your tax home overnight. The deductible portion is generally limited to 50%. Records need to show who was there, where you ate, and what business was discussed. A “client lunch” note on a credit card statement will not hold up.
Uniforms and Safety Gear
Clothing qualifies only when your job requires it and it is not suitable for everyday wear.6Internal Revenue Service. Can I Claim My Expenses as Miscellaneous Itemized Deductions on Schedule A Steel-toed boots, flame-resistant coveralls, hard hats, and branded uniforms all count. A business suit does not, even when your employer expects one, because you could wear it anywhere.
Tools, Software, and Professional Dues
Trades and technical workers often pay for tools, equipment, or software their employer requires but does not supply: a mechanic’s wrenches, a photographer’s editing software, a nurse’s personal stethoscope. Dues to professional organizations also qualify, with one exception: if the group tells you a portion of your dues funds lobbying, that portion is not a business expense.7Internal Revenue Service. Publication 529, Miscellaneous Deductions
Continuing Education and Licenses
Job-related coursework qualifies when it maintains or improves skills you use in your current role, or when your employer or a licensing body requires it to keep your job.8Internal Revenue Service. Topic No. 513, Work-Related Education Expenses Education that qualifies you for a new career does not count, even a related one. A nurse’s continuing education credits qualify. That same nurse’s medical school tuition does not.
Home Office
W-2 employees cannot claim a home office deduction on a federal return. The deduction is reserved for self-employed people. If you work from home as an employee, the only federal route to recovering internet costs, furniture, or utility increases is your employer’s reimbursement plan. A few states require employers to reimburse remote workers; federal law does not.
Getting Reimbursed Without Getting Taxed
Accountable Plans
When an employer runs an accountable plan, reimbursements are tax-free and never appear as wages on your W-2.4Internal Revenue Service. Publication 463 (2025), Travel, Gift, and Car Expenses Three conditions have to be met:
- The expense was incurred while performing services for your employer.
- You submit documentation, such as receipts or an expense report, within 60 days of incurring the cost.
- You return any reimbursement that exceeds your actual expenses within 120 days.
Meet all three and the money stays off your W-2. Miss any one and the IRS reclassifies the payment as taxable compensation.
Non-Accountable Plans
If the arrangement fails any of the three tests, it is a non-accountable plan. Your employer folds the reimbursement into your wages in Box 1 of your W-2, and you pay income tax and payroll tax on every dollar.4Internal Revenue Service. Publication 463 (2025), Travel, Gift, and Car Expenses A flat monthly expense allowance that gets paid regardless of what you actually spend is a common example. So is an arrangement where your employer reduces your stated wages by the reimbursement amount rather than paying it on top. Ask payroll or HR which type of plan applies to you before assuming a reimbursement is tax-free.
What Your Records Have to Show
Good documentation is what keeps a reimbursement tax-free. At a minimum, records should establish the amount, date, location, and business purpose of each expense.9Internal Revenue Service. Revenue Ruling 2003-106 For any single expense over $75, keep an itemized receipt. Below that, a credit card statement or electronic record showing the merchant and amount is generally enough, though your employer’s policy may be stricter. Hotel bills should break out lodging, meals, phone, and other charges separately. The 60-day submission window is not a suggestion. Miss it and the whole reimbursement becomes taxable income.
Federal Deductions After the 2025 Law Change
The Tax Cuts and Jobs Act suspended the ability of W-2 employees to deduct unreimbursed business costs as miscellaneous itemized deductions. That suspension was set to expire at the end of 2025, and many workers were watching for the deduction’s return. It is not returning. The One Big Beautiful Bill Act, signed into law on July 4, 2025, struck the sunset date, making the elimination permanent.1Office of the Law Revision Counsel. 26 USC 67 – 2-Percent Floor on Miscellaneous Itemized Deductions For most W-2 employees, there is no federal deduction path for unreimbursed job costs, now or in any foreseeable future.
A small group of workers can still deduct unreimbursed expenses as an adjustment to gross income using Form 2106:4Internal Revenue Service. Publication 463 (2025), Travel, Gift, and Car Expenses
- Armed Forces reservists traveling more than 100 miles from home in connection with reserve duties. The deduction is capped at the federal per diem rate for lodging and meals plus the standard mileage rate for driving.
- Qualified performing artists who work for at least two performing arts employers during the year and meet specific income thresholds.
- Fee-basis state or local government officials paid entirely through fees rather than salary.
- Employees with impairment-related work expenses, meaning workers with disabilities paying for items they need to do the job, such as specialized equipment or workplace modifications.
If none of those categories fit, Form 2106 is closed to you.10Internal Revenue Service. 2025 Instructions for Form 2106 – Employee Business Expenses
The Educator Deduction That Survived
K-12 teachers, instructors, counselors, principals, and aides who work at least 900 hours during the school year can deduct up to $300 in unreimbursed classroom expenses.11Internal Revenue Service. Topic No. 458, Educator Expense Deduction Married couples where both spouses qualify can deduct up to $600 combined, but neither spouse can exceed $300. Books, supplies, computer equipment, and supplementary classroom materials all count. The deduction goes on Schedule 1, so you do not have to itemize to claim it.
State Reimbursement Laws
Federal law does not require employers to reimburse business costs, but roughly a dozen states and local jurisdictions do. California, Illinois, and Massachusetts have the broadest statutes, generally requiring reimbursement of all necessary expenses incurred in the course of your job. Montana, Iowa, New Hampshire, North Dakota, and South Dakota also have reimbursement requirements, though the scope varies. A handful of cities, including Seattle, have passed their own ordinances covering remote work costs specifically. If your employer refuses to cover a legitimate business expense, check whether your state has a reimbursement statute before you write the money off as a loss.
