How the IRS deadlines work, when it becomes taxable and what happens to unspent cash." canonical: https://engine.com/glossary/cash-advance updated: 2026-11-02 author: "Engine Editorial" --- # Cash advance A cash advance, in business travel, is an expense allowance an employer pays before the trip, which the employee later accounts for and returns any part not spent. Also called: travel advance Not to be confused with: a credit card cash advance, which is a short-term loan against the card's credit line. Updated November 2, 2026 by Engine Editorial ## What is a travel cash advance? A travel cash advance is trip money paid to an employee before the expenses happen. This cheat sheet covers how to think about one, the math on unspent money, the IRS timing rules and where it goes wrong. The detail is further down. ### How to think about it - **It's paid before the expense.** The IRS calls it a travel advance when an employer pays an expense allowance before the expense, in an amount reasonably expected to be no more than the expense. - **It has to be accounted for.** Under an accountable plan, the employee must adequately account to the employer for the advance. - **Unspent money goes back.** Any excess has to be returned within a reasonable period of time. - **Miss the rules and it's wages.** Amounts not accounted for or returned are treated as paid under a nonaccountable plan, which the employer reports with wages in box 1 of the Form W-2. ### The math Return the advance for the days you didn't travel. An employee gets $90 a day for a 5-day trip, a $450 advance, and the trip lasts 3 days. They return $90 x 2 days = $180 _Illustrative example from IRS Publication 463. Per diem rates and plan rules vary by employer and location._ ### The IRS timing safe harbors 1. **Advance.** The employee receives the advance within 30 days of the expense. 2. **Account.** The employee accounts for expenses within 60 days after they were paid or incurred. 3. **Return.** The employee returns any excess within 120 days after the expense was paid or incurred. 4. **Or settle by statement.** The employer sends a statement at least quarterly asking the employee to return or account for open advances, and the employee complies within 120 days. ### Where it goes wrong - **Advancing more than cash costs.** Federal travel rules cap an advance at the traveler's estimated cash expenses. For non-cash expenses, the cap is generally zero. - **Forgetting canceled trips.** Under federal travel rules, an employee whose trip is canceled or postponed indefinitely must refund any money advanced. - **Pulling cash on a credit card.** A credit card cash advance usually carries a fee and a higher interest rate, and interest starts as soon as you withdraw the money. ## Travel advance vs. credit card cash advance | | Travel advance | Credit card cash advance | | --- | --- | --- | | Where the money comes from | The employer, before the expense | The card's line of credit | | What it costs | Not taxed as wages if handled under an accountable plan | Fees plus interest, usually at a higher rate than purchases | | When it's settled | Account for it and return any excess within a reasonable period | Repay it with interest, which starts when you withdraw | ## How it works on Engine With [Engine Direct Bill](https://engine.com/features/direct-bill), Engine extends a line of credit, pays eligible hotels and invoices the company in arrears, so travelers never front the room charge.

Amounts not accounted for or returned are treated as paid under a nonaccountable plan and reported as wages. ### How long does an employee have to return an unused travel advance? A reasonable period, which depends on the facts. The IRS treats returning the excess within 120 days after the expense, or within 120 days of a periodic statement, as reasonable. ### What is the difference between a travel advance and a credit card cash advance? A travel advance is money from your employer that you account for later. A credit card cash advance pulls money from your card's line of credit, works like a short-term loan and comes with fees and interest. ### What happens to a per diem advance if the trip is shorter? The employee returns the advance for days they didn't travel. If they can't prove they traveled on a day they received per diem for, that amount has to be returned within a reasonable period. ## Go deeper - [Engine Direct Bill](https://engine.com/features/direct-bill) - [IRS travel reimbursement rules](https://engine.com/blog/irs-travel-reimbursement-rules) - [Per diem](https://engine.com/glossary/per-diem) - [Petty cash](https://engine.com/glossary/petty-cash) ## Sources 1.
