Suspended, Not Erased: What Employees Must Know About Business Expense Deductions Before 2025 Expires

A Deduction That Vanished From Most Tax Returns

For decades, employees who spent their own money on work-related costs—professional tools, job-related education, union dues, unreimbursed travel—could deduct those expenses as miscellaneous itemized deductions, subject to a 2% adjusted gross income floor. It was not a perfect system, but it provided meaningful relief for workers whose employers did not cover legitimate business costs.

Then came the Tax Cuts and Jobs Act of 2017. Beginning with the 2018 tax year, Congress suspended the deduction for miscellaneous itemized deductions subject to the 2% floor. The change was broad and largely unconditional—applying to the vast majority of W-2 employees regardless of occupation, expense type, or dollar amount involved. For most workers, these deductions simply ceased to exist on the federal return.

The suspension, however, is not permanent. Under current law, it runs through December 31, 2025. What happens after that remains an open legislative question—one with meaningful financial implications for millions of Americans.

The Workers Who Never Lost the Deduction

While the 2017 law swept broadly, Congress carved out three specific categories of employees who retained the ability to deduct unreimbursed business expenses directly on their federal returns. These workers file using Form 2106, and their deductions appear as adjustments to income rather than itemized deductions, making them available regardless of whether the taxpayer itemizes.

Qualifying Performing Artists. Actors, musicians, and other performing artists may deduct unreimbursed employee business expenses if they meet a strict three-part test: they must have worked for at least two employers in the performing arts during the tax year, earned at least $200 from each of those employers, and have allowable business expenses exceeding 10% of gross income from those performing arts services. Additionally, adjusted gross income before the deduction cannot exceed $16,000. That income ceiling has not been adjusted for inflation since the rule was originally written, which significantly limits the pool of workers who qualify in practice.

Fee-Basis State or Local Government Officials. Public officials compensated on a fee basis—meaning they are paid for specific services rendered rather than receiving a fixed salary—may deduct ordinary and necessary business expenses incurred in the performance of their duties. This category is narrower than it might appear; salaried government workers do not qualify.

Reserve Members of the Armed Forces. Members of the Army Reserve, Navy Reserve, Marine Corps Reserve, Air Force Reserve, Coast Guard Reserve, Army National Guard, Air National Guard, and Reserve Corps of the Public Health Service may deduct unreimbursed travel expenses for reserve duty performed more than 100 miles from home. The deduction is limited to the federal per diem rate for lodging and meals and the standard mileage rate for vehicle use.

For everyone else, the federal deduction is currently off the table.

State Returns Complicate the Picture

Federal conformity is not universal. A meaningful number of states did not adopt the TCJA's suspension of miscellaneous itemized deductions and continue to allow employees to deduct unreimbursed business expenses on their state returns. California is among the most prominent examples—employees filing California returns can still claim these deductions under state rules even though the federal deduction is unavailable.

If you reside in a non-conforming state, tracking and documenting unreimbursed employee expenses is not merely a forward-looking exercise. It has immediate, current-year value on your state return. Failing to maintain adequate records because the federal deduction is suspended could mean leaving real money on the table every April.

Why Documentation Matters Even If You Cannot Deduct Today

The suspension expires after 2025. Whether Congress extends it, makes it permanent, or allows it to lapse is genuinely uncertain at this writing. Historically, Congress has sometimes restored lapsed provisions retroactively—occasionally applying them to the full tax year in which they expired. If that pattern holds, taxpayers who have been diligently recording their unreimbursed expenses will be positioned to reconstruct deductible amounts for the relevant period. Those who kept no records will have nothing to work with, even if the law ultimately permits a deduction.

Beyond the legislative uncertainty, contemporaneous documentation is almost always more defensible than records reconstructed from memory or estimates. The IRS expects substantiation that reflects the time, place, business purpose, and amount of each expense. A log assembled after the fact is vulnerable in a way that a running record maintained throughout the year is not.

What Qualifies as an Unreimbursed Employee Business Expense

For workers who currently qualify—and for everyone tracking costs in anticipation of potential legislative changes—understanding what counts matters. Deductible unreimbursed employee business expenses generally include:

• Job-related education that maintains or improves skills required in your current position (not education qualifying you for a new career)
• Tools, supplies, and equipment required for your work that your employer does not provide
• Uniforms and work clothing that are not suitable for everyday wear and are required as a condition of employment
• Union and professional association dues
• Business-related travel, including transportation, lodging, and meals (subject to the 50% meals limitation)
• Home office expenses, provided the space is used regularly and exclusively for work and is the principal place of business

Personal commuting costs—the daily trip between your home and your regular workplace—are not deductible regardless of distance or circumstance.

Building a Tracking System That Works

The most effective approach is one that requires minimal friction to maintain. A dedicated folder or digital tool where receipts are stored at the time of purchase, combined with a simple log noting the business purpose of each expense, provides the foundation the IRS requires. Mileage tracking apps that record trips automatically have made vehicle expense documentation considerably more manageable for workers who travel for work.

Employers who offer accountable reimbursement plans allow employees to submit documented expenses for reimbursement without tax consequences to either party. If your employer has such a plan and you are not using it, that is the more immediate conversation to have—reimbursement eliminates the tax complexity entirely and puts money back in your pocket without depending on any deduction.

The Larger Strategic Point

Tax provisions that appear dormant have a way of becoming relevant again. The suspension of miscellaneous itemized deductions was a significant policy shift, but it came with an expiration date—and that date is approaching. Workers who dismissed this category of expense in 2018 and never returned to it may find themselves unprepared if the deduction revives, either through legislative action or the simple passage of time.

Smart tax planning does not wait for certainty. It accounts for plausible scenarios and maintains the documentation needed to act when the rules shift. If you are a W-2 employee spending meaningful amounts of your own money on work-related costs, the time to start recording those expenditures is now—not after Congress acts.
