How long should a business keep expense reports and travel receipts?

Expense reports and travel receipts are financial records, and like all records their retention is driven by the laws and obligations that apply to them — not by a single universal number. That said, this category has well-established patterns worth understanding.

Why these records matter

Expense reports and the receipts that substantiate them serve as proof. They document that a payment was legitimate, properly authorized, and tied to a business purpose. Because they support tax filings, reimbursements, and audits, they need to survive long enough to back up the position you took on a return or in your books.

Common retention patterns

For most U.S. businesses, expense and travel documentation is tied to tax recordkeeping. Records that support items on a tax return are generally kept for several years — long enough to cover the period in which a return can be examined or amended. In practice many organizations land on a multi-year window (often in the range of three to seven years) for routine expense documentation, reflecting audit and statute-of-limitations considerations. The exact period varies with your jurisdiction, your industry, and the circumstances of the return.

A few records require longer treatment:

• Receipts tied to capital assets may need to be kept for as long as you hold the asset, plus the relevant tax period afterward.
• Expense records caught up in litigation, audit, or investigation must be preserved under a legal hold until that matter resolves, regardless of the normal schedule.

The right way to set the period

Rather than memorizing a number, capture expense reports and travel receipts as a record series on your retention schedule:

1. Identify the legal, fiscal, and operational requirements that apply.
2. Set a single, defensible retention period for the series.
3. Apply it consistently and dispose of records on schedule.

A preservation note

Keeping records longer than required is not a safe default — it raises costs and increases exposure. Whether you store receipts on paper or as scans, make sure the format you choose stays readable for the full retention period, and that scanned images are complete and legible enough to satisfy an auditor.
