Form 2106 Employee Business Expenses: Who Qualifies and How to File

Form 2106, Employee Business Expenses, is now available to only four narrow categories of W-2 workers: Armed Forces reservists traveling more than 100 miles for duty, qualified performing artists who meet a strict income test, fee-basis state or local government officials, and employees with impairment-related work expenses. If you fall outside those four groups, there is no federal deduction for unreimbursed job costs, because the Tax Cuts and Jobs Act suspended the old miscellaneous itemized deduction and the One Big Beautiful Bill Act of 2025 made that repeal permanent.

Who Can Still Use Form 2106

Before you fill in a single line, confirm you belong to one of these four groups. Filing when you don’t qualify wastes effort and invites scrutiny.

Armed Forces reservists. Members of the Army, Navy, Marine Corps, Air Force, or Coast Guard Reserve, the Army or Air National Guard, or the Reserve Corps of the Public Health Service can deduct unreimbursed travel when performing reserve duties more than 100 miles from home. The deduction is capped at the federal per diem rate for lodging, meals, and incidentals, plus the standard mileage rate for driving, plus parking, ferry fees, and tolls.¹

Qualified performing artists. Every prong of the test has to be met: you worked for at least two employers in the performing arts during the year, earned at least $200 from each, had allowable business expenses exceeding 10 percent of your gross performing-arts income, and had adjusted gross income of $16,000 or less before subtracting those expenses. Married artists generally must file jointly, and the $16,000 cap applies to combined AGI.²

Fee-basis state or local government officials. If you are employed by a state or political subdivision and paid in whole or part on a fee basis rather than by salary, you qualify. This covers certain elected officials, notaries, and similar positions paid per transaction.¹

Employees with impairment-related work expenses. If you have a physical or mental disability and pay for goods or services you need to do your job, such as an attendant, adaptive equipment, or workspace modifications, those costs are deductible. Unlike the other three categories, they flow to Schedule A rather than as an above-the-line adjustment.³

In every case, expenses must be unreimbursed. If your employer pays you back under an accountable plan, that reimbursement is already excluded from your wages and there is nothing left to deduct.

Why Everyone Else Is Out

Before 2018, any W-2 employee could deduct unreimbursed job expenses as a miscellaneous itemized deduction, subject to a floor of 2 percent of adjusted gross income.³ The TCJA suspended that entire category through 2025, and the One Big Beautiful Bill Act made the repeal permanent. Home office costs, professional development, union dues, job-search expenses — for a typical W-2 worker, none of these produce a federal deduction, whatever the amount.

If your employer offers an accountable plan, use it. A reimbursement made under a plan that requires you to substantiate expenses and return any excess is excluded from gross income and does not appear in Box 1 of your W-2.⁴ If there is no plan and you fall outside the four groups, you absorb the cost.

What Expenses Qualify

Every claimed expense must be ordinary and necessary for your work. “Ordinary” means common in your line of work; “necessary” means helpful and appropriate. The cost must have been paid or incurred during the tax year, and your employer must not have reimbursed it.

Travel Away From Home

When your duties require overnight travel away from your tax home, you can deduct airfare, train tickets, rental cars, lodging, and local transportation at your destination.⁵ Meals while traveling are deductible at 50 percent of the actual cost, or you can use the federal per diem rate for the destination.

The work location has to be temporary. Travel expenses to an assignment expected to last one year or less are deductible. Once you realistically expect the assignment to run longer than a year, expenses stop being deductible, even if it ends up wrapping earlier.⁵

Local Transportation

Driving a personal vehicle during the workday for job purposes counts: visiting clients, moving between job sites, or going from your regular office to a temporary work location. Commuting from home to your regular workplace never counts, regardless of distance.¹ Parking and tolls at business destinations qualify; parking at your regular office does not.

Tools, Uniforms, and Job Necessities

Specialized tools, safety equipment, and uniforms not suitable for everyday wear are deductible, along with cleaning and maintenance for those uniforms. Education that maintains or improves skills required for your current job can qualify, but education preparing you for a new career does not.

Impairment-Related Expenses

For employees with disabilities, the cost of goods or services needed to perform the job, such as a reader, an interpreter, specialized transportation to work, or adaptive technology, counts as an impairment-related work expense. These are specifically excluded from the old 2-percent-of-AGI floor and remain deductible after the permanent repeal.³

Filling Out the Form

Form 2106 has two parts. Part I totals your expenses and subtracts reimbursements. Part II handles vehicles specifically.

Part I: Expenses and Reimbursements

The expense lines split your costs into categories:

Line 1: vehicle expenses calculated in Part II.
Line 2: parking, tolls, and local transportation that did not involve overnight travel. Not commuting.
Line 3: lodging and transportation tied to overnight travel away from your tax home. Meals go elsewhere.¹
Line 4: other business expenses, including education, business gifts, trade publications, tools, and uniforms.
Line 5: overnight travel meals and other deductible business meals. The 50-percent limit is applied later in the calculation.

Line 7 captures employer reimbursements reported in Box 12 of your W-2 with code L. Do not enter reimbursements that are already included in Box 1 wages. Line 10 is your final deductible amount after subtractions and the meal reduction.¹

Part II: Vehicle Expenses

Part II asks when you placed the vehicle in service, total miles driven, business miles, commuting miles, and other personal miles. You then choose one of two methods.

The standard mileage rate multiplies business miles by the IRS rate; for 2026 that is 72.5 cents per mile, of which 26 cents is treated as depreciation.⁶ It is simpler and fits most eligible filers.

The actual expense method tracks every vehicle cost, including fuel, oil, repairs, insurance, registration, tires, and depreciation, then applies your business-use percentage. Depreciation on passenger vehicles is capped under Section 280F, with the first-year cap for 2026 vehicles that qualify for bonus depreciation at $20,300.⁷

Switching Methods Later

Your first-year choice constrains what you can do afterward. Start with the standard mileage rate and you can switch to actual expenses later, but you must use straight-line depreciation from that point on. Start with actual expenses and claim MACRS depreciation, Section 179, or bonus depreciation, and you can never switch to the standard mileage rate for that vehicle.⁸ For a leased vehicle, whichever method you pick applies for the entire lease.

Records You Need to Keep

The IRS can disallow the whole deduction if your records don’t hold up. The standard is contemporaneous documentation: created at or near the time of the expense, not reconstructed at tax time.

For each expense, document the amount, the date, the place or vendor, and the business purpose. Meals add a fifth element: the business relationship of the people present. Keep a receipt for any expense of $75 or more, and for all lodging regardless of amount. Expenses under $75 still need a log entry with the four elements.

A valid mileage log records the date of each trip, starting location and destination, business purpose, and miles driven. Also record odometer readings at the start and end of the tax year, and when you start or stop using a vehicle for business, so the IRS can verify your business-use percentage.

Keep receipts, logs, and supporting documents for at least three years from the date you file. If you underreport income by more than 25 percent, the assessment window extends to six years. Fraudulent or unfiled returns have no time limit.⁹

Where the Number Lands on Your Return

How the Line 10 amount moves onto your return depends on which of the four groups you belong to. Putting it on the wrong schedule can void the deduction.

Above-the-Line: Reservists, Performing Artists, Fee-Basis Officials

These three groups report the Line 10 amount on Schedule 1 (Form 1040), Line 12, labeled “Certain business expenses of reservists, performing artists, and fee-basis government officials.”¹⁰ It is an above-the-line deduction, so it reduces AGI directly and applies whether or not you itemize. A lower AGI can also widen your eligibility for other tax benefits that phase out at higher incomes. Attach the completed Form 2106 to your return.¹

For reservists, only the portion of Line 10 attributable to travel more than 100 miles from home flows to Schedule 1, and the deductible amount is capped at the federal per diem and standard mileage rates no matter what you actually spent.¹¹

Schedule A: Impairment-Related Expenses

Employees with disabilities send their Line 10 amount to Schedule A, Line 16, under “Other Itemized Deductions.”¹² Because impairment-related work expenses were carved out of the 2-percent floor, they remain fully deductible after the permanent repeal.³ You do have to itemize to claim them, so if the standard deduction produces a better overall result, this particular benefit goes unused.

Statutory Employees and the Self-Employed Use Schedule C

If your W-2 has the “Statutory employee” box checked, skip Form 2106. Statutory employees, including full-time life insurance salespeople, certain delivery drivers, home workers, and traveling salespeople, report income and expenses on Schedule C.¹³ Self-employed workers and independent contractors also use Schedule C. Form 2106 exists only for the four groups of common-law employees described above.

What Happens If You Can’t Back Up the Claim

Claiming expenses you can’t substantiate can cost more than just the denied deduction. When an underpayment stems from negligence or disregard of the rules, the IRS can assess an accuracy-related penalty of 20 percent of the underpayment.¹⁴ Negligence here includes failing to make a reasonable effort to comply with recordkeeping rules, which is exactly the situation when someone claims a vehicle deduction without a mileage log or deducts travel without receipts. The penalty sits on top of the added tax you owe, with interest running from the original due date.
