Non-Reimbursable Expense

A cost incurred by an employee that falls outside the company's expense reimbursement policy and will not be repaid by the employer, typically because it serves a personal rather than business purpose or exceeds approved spending limits.

Key Takeaways

A non-reimbursable expense is a cost an employee incurs that the company will not repay because it falls outside the boundaries of the organization's expense policy. The designation isn't arbitrary. It reflects a deliberate policy decision about which costs serve a legitimate business purpose and which are personal or excessive.

  • Under IRS rules, only expenses that are "ordinary and necessary" for business qualify for tax-free reimbursement under an accountable plan. Costs that fail this test are non-reimbursable by definition [1].
  • Common non-reimbursable items during business travel include personal toiletries, unapproved cabin upgrades, minibar charges, traffic fines, entertainment without a business purpose, and expenses for personal side trips.
  • Navan flags potential non-reimbursable charges at the time of expense submission by matching merchant category codes and receipt details against the company's policy rules.
  • The Tax Cuts and Jobs Act suspended employees' ability to deduct unreimbursed business expenses as miscellaneous itemized deductions through 2025, making clear reimbursement policies more important than ever [2].

What is a Non-Reimbursable Expense?

A non-reimbursable expense is any cost an employee incurs that the company's travel and expense (T&E) policy explicitly excludes from reimbursement. The expense may have occurred during a business trip, but the company determines it doesn't meet the criteria for repayment, typically because it serves a personal purpose, exceeds policy limits, or lacks required documentation.

The concept exists because business travel creates a gray zone between personal and professional spending. When a sales manager extends a client visit by two days for personal sightseeing, the hotel nights for those extra days are non-reimbursable. When an engineer orders room service at 11 p.m. during a conference trip, the meal is likely reimbursable. The expense policy draws the line.

Non-reimbursable doesn't necessarily mean "illegitimate." An employee might incur a cost that's perfectly reasonable but falls outside what the company has agreed to cover. The distinction matters for three reasons: it determines whether the employee or the company absorbs the cost, it affects the company's tax deductions, and it shapes employee expectations about what travel benefits they receive.

Common Non-Reimbursable Expenses in Business Travel

Most corporate travel policies explicitly list non-reimbursable items to reduce ambiguity. The following categories cover the majority of exclusions.

Category

Examples

Why Non-Reimbursable

Personal care

Toiletries, clothing, haircuts, gym fees

Personal expenses regardless of when purchased

Unapproved upgrades

First-class airfare without pre-approval, premium hotel suites beyond policy limits

Exceeds policy spending thresholds

Entertainment without business purpose

Personal streaming, in-room movies, minibar, personal sightseeing

No direct business connection

Fines and penalties

Traffic tickets, parking violations, late fees

Result of personal negligence, not business activity

Personal travel extensions

Extra hotel nights, meals, and transportation for leisure days added to a business trip

Personal purpose, not business

Spousal or family travel

Airfare, hotel, or meals for non-employees accompanying the traveler

Personal unless specifically pre-approved for business events

Personal documents

Passport renewals, visa fees for personal travel, driver's license

Personal responsibility unless required for a specific business trip

Excessive meals

Meals exceeding per diem or dollar-cap limits

Policy cap exceeded

The IRS provides the framework for these decisions. To be deductible by the company and tax-free for the employee, an expense must meet the "ordinary and necessary" standard: common and accepted in the industry, and helpful or appropriate for the business [1]. Expenses that fail this test aren't eligible for tax-free reimbursement under an accountable plan, which makes them non-reimbursable by default.

How Do Non-Reimbursable Expenses Affect Tax Treatment?

The tax implications of non-reimbursable expenses changed significantly with the Tax Cuts and Jobs Act (TCJA) of 2017.

Before TCJA (pre-2018). Employees who incurred unreimbursed business expenses could deduct them on Schedule A as miscellaneous itemized deductions, subject to a 2% adjusted gross income (AGI) floor. This provided a partial tax benefit even when the employer didn't reimburse the cost.

After TCJA (2018-2025). The TCJA suspended miscellaneous itemized deductions, eliminating the employee's ability to deduct unreimbursed business expenses on their personal tax return [2]. This means employees bear the full after-tax cost of any non-reimbursable business expense with no tax offset.

For the employer. Non-reimbursable expenses are irrelevant to the company's tax return since the company never pays them. However, expenses the company does reimburse under an accountable plan are fully deductible (subject to the 50% limitation on meals). This tax asymmetry creates a strong incentive for companies to maintain clear, comprehensive reimbursement policies that cover legitimate business costs.

Best Practices for Managing Non-Reimbursable Expenses

List exclusions explicitly in the travel policy. Vague policies generate disputes. Instead of "personal expenses are not reimbursable," list specific items: minibar charges, in-room entertainment, personal care products, alcohol above policy limits, spousal travel costs, traffic fines, and personal side trips. The more specific the exclusion list, the fewer gray-area submissions finance teams must adjudicate.

Flag non-reimbursable charges before submission. When employees submit expense reports with items that match non-reimbursable expense categories, the system should flag them in real time rather than waiting for manual review. Merchant category codes and receipt scanning can identify common non-reimbursable items (liquor stores, entertainment venues, personal care retailers) before the report reaches a manager.

Separate personal charges on corporate cards. When employees use company cards for personal purchases during travel (which many policies permit within limits), those charges should be coded as non-reimbursable and routed to payroll deduction. Clear card policies prevent personal charges from accidentally flowing into business expense reimbursement.

Handle gray areas with pre-approval. Some expenses sit in a genuine gray zone. A $200 team dinner during a conference is clearly business. A $200 dinner with a personal friend who happens to be in the same city is clearly personal. A $200 dinner with a potential hiring candidate is gray. Establish a pre-approval process for borderline expenses so employees get clarity before incurring the cost.

Communicate during onboarding and before trips. The most common source of non-reimbursable expense disputes is ignorance, not bad intent. New employees who haven't internalized the policy submit charges they genuinely believe are covered. A brief policy review during onboarding and an automated reminder before each trip reduces exception rates significantly.

When Should You Consider Expanding Reimbursable Categories?

Strict non-reimbursable lists can backfire if they create employee friction or drive behavior that costs the company more in other ways.

  • Wi-Fi and connectivity: Some policies classify in-flight Wi-Fi as non-reimbursable. But an employee who can't work during a 5-hour flight loses productive hours that cost the company far more than the $15 Wi-Fi fee. Reclassifying connectivity as reimbursable often has a positive ROI.
  • Wellness during extended travel: Gym fees and wellness expenses on trips lasting a week or more address traveler fatigue and burnout, which are real cost centers in companies with heavy travel programs. Some progressive policies now reimburse these within limits.
  • Visa and documentation fees: When travel to a specific country is required for business, the visa fee and passport renewal required to make the trip happen are arguably business expenses, even if the employee retains the document for personal use.
  • Expense Report: The document where non-reimbursable charges may appear and must be flagged, separated, or removed before approval.
  • Expense Categories: The classification system that determines whether a charge falls into a reimbursable or non-reimbursable bucket.
  • Cash Advance: Prepaid travel funds that must be fully reconciled, with any personal or non-reimbursable spending returned to the company.
