Getting Paid Back

Filing expenses is the tax nobody warns you about on a work trip. Here’s how reimbursement actually works — what’s covered, what needs a receipt, and how it’s taxed — in plain terms, with the IRS rules linked.

The vendors who answer these questions are selling you expense software. We’re not — so here’s the straight version of how getting paid back actually works, with the IRS rules linked so you can check them yourself.

General information — rules and policies change. Confirm current specifics with the relevant authority (your company, the airline, the government) or a professional. Where a public rule applies, its primary source is linked.

How do I file a travel expense report?

Keep receipts as you go, log each cost against the trip with its business purpose, and submit through your company’s system (or its mandated app). The IRS calls this “adequate accounting” — for each expense you record the amount, date, place, and business reason. Source: IRS Publication 463 ↗.

What travel costs can I get paid back for?

The ordinary and necessary costs of business travel: airfare, lodging, ground transport, baggage fees, business meals, and tips. Personal costs aren’t reimbursable. Your company’s policy sets the caps; the IRS defines the categories. Source: IRS Publication 463 ↗.

How long does it take to get travel expenses paid back?

That’s set by your company, not the IRS — commonly one to four weeks after a complete, approved report. Under an IRS “accountable plan,” reimbursement has to happen within a reasonable time, so submitting promptly and completely is the fastest path. Source: IRS Publication 463 (accountable plans) ↗.

Do I need receipts for every work travel cost?

For tax purposes the IRS requires documentary evidence for lodging and for larger expenses (as a rule of thumb, $75 and up); smaller ones still need a record but not always a receipt. But your employer can require receipts for everything — and many do — so follow the stricter of the two. Source: IRS Publication 463 ↗.

How do I track expenses while traveling?

Capture each receipt the moment you get it (a photo or the app), note the business purpose, and reconcile daily so nothing slips. The discipline is boring and it’s the whole game — a lost receipt is usually a cost you eat.

What is the best app for travel expenses?

Usually whichever one your company mandates — Concur, Expensify, Ramp, and Navan are the common ones, and you rarely get to pick. The independent truth the vendors won’t tell you: the “best” expense app is the one your finance team already runs, so learn it well rather than fight it.

Can I expense my hotel wifi?

Generally yes — hotel internet used for work is an ordinary business travel expense — but it’s policy-dependent, so check your company’s rules and keep the receipt or the line item on the folio.

What happens if I lose a receipt for work?

Don’t panic — reconstruct it. The IRS accepts a written record (amount, date, place, business purpose) alongside a card statement when a receipt is genuinely missing, and most companies have a lost-receipt affidavit. Do it promptly, while you still remember the details. Source: IRS Publication 463 (adequate records) ↗.

Can I expense a checked bag fee?

Almost always yes — baggage fees on business travel are a standard reimbursable cost. Keep the receipt; your policy may cap the number of bags it’ll cover.

How do I split a bill for a work meal?

If you’re hosting, pay the whole thing and expense it with the attendees and business purpose noted — the IRS wants the “who” and “why” for meals. If you’re splitting personally, keep your share clean and separate from anything you’ll expense. Source: IRS Publication 463 (meals) ↗.
