What Are Miscellaneous Expenses? Examples, Deductions, and Rules

Miscellaneous expenses are the small, irregular costs that don’t fit into a dedicated budget or accounting category — things like a wire transfer fee, a one-off postage run, a notary charge, or a replacement part for a broken fixture at home. For businesses, most of these are still deductible if they’re ordinary and necessary. For individuals, they aren’t: the federal deduction for miscellaneous itemized expenses was suspended in 2018 and made permanent in 2025.

What Counts as a Miscellaneous Expense

The defining traits are low dollar value and no repeating pattern. If a cost shows up often enough to track on its own, it earns its own category. The miscellaneous label exists to keep books clean without letting small spending disappear.

In a household budget, that looks like a birthday gift for a coworker, a one-time app subscription, an annual club membership, or a small household item that doesn’t belong under groceries or utilities. In a business ledger, it’s bank service charges, wire transfer fees, professional association dues, postage for a single mailing, notary fees, filing fees for maintaining a business registration, minor software licenses, and small office supplies that don’t reach the threshold for a dedicated line.

Why Individuals Can’t Deduct These Anymore

Before 2018, an individual who itemized could write off certain miscellaneous costs — unreimbursed employee expenses, tax preparation fees, investment advisory fees, safe deposit box rental — to the extent they exceeded 2% of adjusted gross income. The Tax Cuts and Jobs Act suspended that deduction, and the One Big Beautiful Bill Act signed on July 4, 2025 made the suspension permanent.1Office of the Law Revision Counsel. 26 U.S. Code 67 – 2-Percent Floor on Miscellaneous Itemized Deductions The statute now says no miscellaneous itemized deduction is allowed for any tax year beginning after December 31, 2017, with no expiration.

So tax prep software, unreimbursed work travel, union dues, investment management fees, and job search costs are permanently nondeductible for individual filers. Most people take the standard deduction anyway — for 2026 that’s $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household.2Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Even filers who itemize because of large mortgage interest or charitable gifts get nothing for miscellaneous costs.

Employees Who Can Still Deduct Work Expenses

Four narrow categories of employees can still deduct unreimbursed work expenses on Form 2106. These claims run through Schedule 1 (or Schedule A for the last group), not the repealed miscellaneous itemized bucket, so they survived the change.3Internal Revenue Service. Instructions for Form 2106 – Employee Business Expenses

  • Armed Forces reservists can deduct travel for reserve duties more than 100 miles from home.
  • Qualified performing artists can deduct if they worked for at least two employers in the performing arts, earned $200 or more from each, had business expenses exceeding 10% of performing arts income, and had adjusted gross income of $16,000 or less before the deduction.
  • Fee-basis state or local government officials can deduct job-related expenses when they’re paid on a fee basis rather than a salary.
  • Employees with impairment-related work expenses can deduct disability-related costs necessary to do the job, reported on Schedule A.

Everyone else has one practical route to tax-free treatment: an employer accountable plan, under which your employer reimburses substantiated business expenses tax-free and you return any excess.4eCFR. 26 CFR 1.62-2 – Reimbursements and Other Expense Allowance Arrangements Without an accountable plan and without membership in the four groups above, work expenses come out of after-tax pay.

How Businesses Deduct Miscellaneous Costs

Businesses work under a different standard. Under 26 U.S.C. § 162, a business can deduct any expense that is both ordinary (common and accepted in the industry) and necessary (helpful and appropriate for the business).5Office of the Law Revision Counsel. 26 U.S. Code 162 – Trade or Business Expenses Bank fees, professional dues, minor office supplies, and similar small costs all qualify if they have a legitimate business purpose.

Sole proprietors and single-member LLCs report these on Schedule C (Form 1040).6Internal Revenue Service. About Schedule C (Form 1040), Profit or Loss from Business (Sole Proprietorship) Corporations use Form 1120.7Internal Revenue Service. About Form 1120, U.S. Corporation Income Tax Return Partnerships and S corporations file their own returns, but the ordinary-and-necessary test is the same across entity types.

De Minimis Safe Harbor for Small Purchases

When a business buys small equipment or tangible property, the de minimis safe harbor election lets it deduct the cost right away instead of depreciating it. The threshold is $2,500 per item without audited financial statements (which covers most small businesses) or $5,000 per item with them. You make the election on the return each year, and it applies only to items at or below the threshold; anything above still follows normal depreciation rules.

Business Meals and Entertainment in 2026

Meals and entertainment show up constantly in miscellaneous spending, and the rules have narrowed. Entertainment — sporting event tickets, concert outings with clients, golf — is fully nondeductible and has been since 2018.

Business meals remain 50% deductible when the food isn’t lavish, the taxpayer or an employee is present, and there’s a clear business purpose. A new restriction took effect on January 1, 2026: meals provided through an employer-operated eating facility, and meals furnished for the employer’s convenience under Section 119, are now fully nondeductible.8Internal Revenue Service. Treasury Decision 9925 – Meals and Entertainment Expenses Under Section 274 Employers subsidizing company cafeterias or providing free on-site meals lost that deduction entirely.

Costs That Never Qualify

Some expenses look deductible but are barred by statute regardless of how they’re booked.

  • Government fines and penalties, including parking tickets, OSHA fines, and regulatory penalties, cannot be deducted.5Office of the Law Revision Counsel. 26 U.S. Code 162 – Trade or Business Expenses
  • Lobbying and political contributions, including communications with executive branch officials about policy, cannot be deducted.
  • Bribes and illegal payments, domestic or foreign, cannot be deducted; that includes payments violating the Foreign Corrupt Practices Act.
  • Commuting from home to a regular workplace is a personal cost, not a business one.9Internal Revenue Service. Publication 529, Miscellaneous Deductions
  • Everyday clothing isn’t deductible even if you only wear it at work. Uniforms and protective gear not suitable for street wear can qualify.

Misclassifying personal costs as business deductions triggers the accuracy-related penalty under 26 U.S.C. § 6662: 20% of the underpaid tax, or 40% for a gross valuation misstatement.10Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments The IRS watches for patterns like personal meals booked as client entertainment, family trips labeled business travel, and home furnishings coded as office expenses.

Hobby or Business? The Classification Matters

If a side activity sometimes makes money and sometimes doesn’t, the IRS may treat it as a hobby rather than a business. Hobby income is fully taxable, but hobby expenses are not deductible at all under the permanent suspension of miscellaneous itemized deductions. A real business can deduct its ordinary and necessary costs and can even produce a loss that offsets other income.

The IRS weighs nine factors:11Internal Revenue Service. Know the Difference Between a Hobby and a Business

  • Whether you keep complete and accurate books and records
  • Whether you run the activity like similar profitable businesses
  • Whether you change methods to improve profitability
  • Whether you or your advisors have studied the business practices of the activity
  • Whether you follow expert advice
  • How much personal time and effort you invest, especially when the activity has no recreational appeal
  • Whether you’ve converted similar activities from unprofitable to profitable in the past
  • Whether you expect to profit from appreciation of assets used in the activity
  • Whether the activity has elements of personal pleasure or recreation

No single factor decides it. But an Etsy shop or horse farm that consistently loses money without genuine efforts at profitability risks reclassification, which means tax on every dollar of income with nothing to offset it.

Records You Need to Keep

Whether you’re claiming a business deduction or just tracking spending, documentation is what stands up in an audit. The IRS expects supporting records for every expense — receipts, invoices, bank statements, or digital transaction logs — showing payee, amount, date, and what was purchased.12Internal Revenue Service. What Kind of Records Should I Keep

How long to keep them depends on the situation:13Internal Revenue Service. How Long Should I Keep Records

  • Three years from the date you filed the return, or two years from the date you paid the tax, whichever is later. This is the baseline.
  • Six years if you omitted more than 25% of your gross income from a return.
  • Seven years if you claimed a deduction for worthless securities or bad debt.
  • Indefinitely if you never filed a return or filed a fraudulent one; there is no statute of limitations.

Three years is the floor, not a suggestion. Without documentation, the IRS disallows the deduction and charges interest on the additional tax from the original due date. Photographing receipts and filing them by month is enough to head off most audit trouble before it starts.
