What a claim needs, the IRS accountable plan rules and what makes it taxable." canonical: https://engine.com/glossary/expense-claim updated: 2026-11-02 author: "Engine Editorial" --- # Expense claim An expense claim is an employee's request to be paid back for business expenses, usually made on an expense report with receipts attached. Also called: reimbursement claim Not to be confused with: a claim for tax relief filed with a tax authority. Updated November 2, 2026 by Engine Editorial ## What is an expense claim? An expense claim is how an employee asks the company to pay back money spent on business. This cheat sheet covers how to think about one and what can turn a tax-free reimbursement into taxable pay. The detail is further down. ### How to think about it - **It usually rides on an expense report.** The employee lists each expense with its business purpose, date and location, attaches receipts and totals the amount claimed. - **A supervisor usually approves it.** The report usually has to be authorized by a supervisor before the expense is reimbursed. - **The plan decides the tax.** Reimbursements under an accountable plan aren't reported as pay. Reimbursements under a nonaccountable plan are. - **Deadlines have a safe harbor.** The IRS treats accounting for an expense within 60 days, and returning any excess within 120 days, as a reasonable period. ### What makes a reimbursement taxable - **Late or missing paperwork.** Amounts that fail any of the three accountable plan rules are generally treated as paid under a nonaccountable plan. - **Keeping the excess.** If an employee doesn't return money beyond the substantiated expenses within a reasonable time, that excess is treated as paid under a nonaccountable plan. - **Paying back non-business costs.** Reimbursing nondeductible costs, such as meals when working late at the office, is treated as paid under a nonaccountable plan. - **Repaying through a pay cut.** An arrangement that repays business expenses by reducing reported wages is treated as a nonaccountable plan. ## Accountable plan vs. nonaccountable plan | | Accountable plan | Nonaccountable plan | | --- | --- | --- | | What it requires | A business connection, adequate accounting within a reasonable time and the return of any excess | Fails one or more of those three rules | | On the employee's W-2 | Not reported as pay | Reported as pay | | Who chooses | The employer | The employer | ## How it works on Engine With [Engine Direct Bill](https://engine.com/features/direct-bill), Engine pays eligible hotels and invoices the company in arrears, so travelers never front the room charge.

The claim is the request for reimbursement, and the expense report is the usual document it's made on, itemizing each expense and the total claimed. ### Are expense claim reimbursements taxable? Not when they're paid under an accountable plan, which requires a business connection, adequate accounting within a reasonable time and the return of any excess. Reimbursements under a nonaccountable plan are reported as pay on the employee's Form W-2. ### How long does an employee have to submit an expense claim? Company policy sets the deadline, and most companies ask for reports within 14 to 30 days of the trip. For tax purposes, the IRS treats accounting within 60 days of the expense as a reasonable period. ### What happens to a travel advance that isn't fully spent? The employee returns the excess. Under the IRS safe harbor, that means within 120 days of the expense; amounts kept beyond the substantiated expenses are treated as paid under a nonaccountable plan. ### Can employees deduct business expenses the company didn't reimburse? Most can't. Miscellaneous itemized deductions subject to the 2% floor are suspended for tax years after 2017, so only a few groups, such as Armed Forces reservists and qualified performing artists, can still use Form 2106. ## Go deeper - [Expense report](https://engine.com/glossary/expense-report) - [Business travel expense report template](https://engine.com/templates/business-travel-expense-report-template) - [IRS travel reimbursement rules](https://engine.com/blog/irs-travel-reimbursement-rules) - [Engine Direct Bill](https://engine.com/features/direct-bill) ## Sources 1.
