A state deductible employee expense is a work-related cost you paid out of your own pocket that your state lets you subtract from taxable income on your state return. With the federal write-off for unreimbursed employee expenses now permanently gone for most workers, the state return is the only place ordinary W-2 employees can still recover these costs. Which expenses qualify, whether a threshold applies, and what paperwork you need all depend on your state’s rules, but the underlying tests are consistent enough to work through in one sitting.
Why This Is Now a State-Only Question
The Tax Cuts and Jobs Act suspended the federal miscellaneous itemized deduction for unreimbursed employee expenses from 2018 through 2025. The One, Big, Beautiful Bill Act made that elimination permanent, and the IRS confirmed in Notice 2026-10 that the disallowance now covers “all miscellaneous itemized deductions that are subject to the two-percent of adjusted gross income floor under § 67, including unreimbursed employee travel expenses.”1Internal Revenue Service. 2026 Standard Mileage Rates Notice 2026-10 For a typical employee, the federal return no longer offers anything for job costs. States that decoupled from the federal code on this issue still do.
The Core Test an Expense Must Pass
Whatever state you’re in, the baseline comes from 26 U.S.C. § 162: the expense must be “ordinary and necessary” for carrying on your trade or business.2Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses Ordinary means common and accepted in your line of work. Necessary means helpful and appropriate for the job. It doesn’t have to be indispensable.
Two more requirements do most of the work in practice:
- You paid it out of pocket, with no reimbursement from your employer.
- It isn’t personal. Commuting from home to your regular workplace doesn’t count. Neither does clothing you could wear off the job, or meals you’d eat anyway.
What Kinds of Expenses Qualify
Travel Between Work Sites
Driving between job sites during the workday, traveling to meet clients, or heading to a temporary assignment counts as deductible business travel. You can claim vehicle costs using the IRS standard mileage rate, which is 72.5 cents per mile for 2026,1Internal Revenue Service. 2026 Standard Mileage Rates Notice 2026-10 or track actual costs like gas, insurance, and depreciation. Most people find the mileage rate simpler.
A temporary work assignment away from your regular workplace qualifies for travel deductions, including lodging, but only if the assignment lasts one year or less. If you realistically expect it to run longer than a year, your travel expenses become nondeductible from the day that expectation forms, even if you leave sooner.3Internal Revenue Service. Topic No. 511, Business Travel Expenses
Protective Clothing and Tools
Work clothing is deductible only when your employer requires you to wear it and it is not suitable for everyday use. Safety boots, hard hats, work gloves, and protective goggles clear that bar easily. A business suit does not, even if your employer requires professional attire, because you could wear it to dinner. Uniforms with company logos or occupation-specific gear like scrubs generally qualify.
Tools and equipment you buy for the job follow the same ordinary-and-necessary standard. A mechanic buying wrenches or a nurse buying a stethoscope has a straightforward case, provided the employer required the item and didn’t cover it.
Work-Related Education
Tuition, textbooks, and course fees are deductible when the education maintains or improves skills you need in your current job, or when your employer or a licensing board requires the coursework to keep your position. Renewing a professional license falls into this category.4Internal Revenue Service. Topic No. 513, Work-Related Education Expenses
One line the IRS enforces strictly: education that qualifies you for a new trade or profession is never deductible, even when it also improves your current skills. A registered nurse taking advanced nursing courses can deduct them. A registered nurse in medical school cannot.4Internal Revenue Service. Topic No. 513, Work-Related Education Expenses
Professional Dues and Subscriptions
Union dues, professional association memberships, and subscriptions to trade journals related to your field are deductible when your employer doesn’t cover them. These are among the most common unreimbursed employee expenses, especially in unionized industries and licensed professions.
Business Meals
Meals with a clear business purpose, such as eating while traveling for work or meeting a client, are deductible at 50% of the cost.5Office of the Law Revision Counsel. 26 USC 274 – Disallowance of Certain Entertainment, Etc., Expenses A $30 working lunch produces a $15 deduction. Keep the receipt and note who you ate with and the business topic. Auditors look for these details.
How Employer Reimbursement Plans Affect Your Deduction
If your employer maintains an accountable reimbursement plan, expenses covered by that plan are not deductible. An accountable plan requires a business connection, substantiation with receipts within a reasonable time, and return of any excess reimbursement. Payments under an accountable plan are tax-free and don’t appear on your W-2.
The trap that hurts people: if your employer has an accountable plan and you simply didn’t submit your receipts, most states will deny the deduction for those expenses. You had a reimbursement path and chose not to use it. Only costs the plan doesn’t cover, or amounts above plan limits, qualify as truly unreimbursed.
If your employer has no reimbursement plan, or uses a nonaccountable plan where reimbursements show up as taxable wages on your W-2, your out-of-pocket expenses are fully eligible for a state deduction.
How States Structure the Deduction
States that still allow unreimbursed employee expense deductions have chosen to decouple from the federal code on this issue. California, New York, and Pennsylvania are well-known examples, and other states permit the deduction as well. Each state sets its own rules for which expenses qualify, what forms to file, and whether a threshold applies. Check your state tax agency’s current-year instructions, because conformity changes on state timelines.
In most states offering the deduction, you have to itemize your state deductions rather than take the standard amount. Some taxpayers find their unreimbursed expenses, combined with other itemized deductions like mortgage interest and charitable contributions, push them past the state standard deduction. Others find itemizing doesn’t save enough to justify the effort. Run the numbers both ways before committing.
The 2% AGI Floor
Many states that still allow these deductions apply a 2% floor drawn from the old federal rule under 26 U.S.C. § 67.6Office of the Law Revision Counsel. 26 USC 67 – 2-Percent Floor on Miscellaneous Itemized Deductions You can only deduct the portion of your total miscellaneous expenses that exceeds 2% of your adjusted gross income. If your AGI is $60,000, that floor is $1,200. Spend $2,500 on qualifying expenses and you deduct $1,300.
Small expenses scattered across the year often don’t clear the floor at all. Workers with high unreimbursed costs relative to income benefit most. A few hundred dollars a year in supplies will likely be wiped out entirely.
Documentation That Survives an Audit
The difference between a successful deduction and a denied one almost always comes down to paperwork. State revenue agencies audit employee expense deductions, and vague records get rejected.
For vehicle expenses, keep a mileage log showing the date, starting and ending locations, business purpose, and miles driven for each trip. The IRS requires adequate records or sufficient corroborating evidence for any transportation deduction.7Internal Revenue Service. Topic No. 510, Business Use of Car A spreadsheet or tracking app updated throughout the year is far more credible than a log reconstructed at tax time.
For purchases like tools, clothing, or course fees, save the receipt and note the business purpose. Keep a copy of your employer’s reimbursement policy, or a written statement from your employer confirming that no plan exists. That documentation is what proves the expense was genuinely unreimbursed.
Retain supporting records for at least three years after filing.8Internal Revenue Service. How Long Should I Keep Records For most employees claiming straightforward work expenses, three years is the operative window, and longer retention costs nothing.
Reporting the Deduction on Your State Return
Forms depend on the state. Several states require a version of federal Form 2106 completed with state-specific figures and attached to the state return. Others use their own supplemental schedules. Look for references to “unreimbursed employee expenses” or “employee business expense adjustments” in your state’s current-year instructions.
Calculate your total qualifying expenses, apply the 2% AGI floor if your state uses one, and enter the result on the designated line. Filing software typically walks through this, but check that the amounts match your records, because automated calculations can miss state-specific adjustments. Discrepancies between claimed amounts and supporting documentation can trigger notices, interest, and penalties, so verifying the math before filing pays for itself.
If You Fit a Federal Carve-Out
A few worker categories can still deduct unreimbursed expenses on the federal return using Form 2106, because their deductions are classified as adjustments to gross income rather than itemized deductions.9Internal Revenue Service.
