What it is
A missing receipt affidavit — also called a lost receipt form, missing receipt declaration, or lost receipt affidavit — is a short attestation you sign in place of documentation. By signing it you confirm the expense was incurred, was for business purposes, has not been and will not be claimed elsewhere, and that you have made a reasonable effort to obtain the receipt.
What it needs to contain
- Your name, department, and the expense report reference
- Merchant name and transaction date
- Exact amount, including tax and tip where relevant
- An itemized description of what was purchased
- The business purpose, stated specifically
- Attendees, for meals and entertainment
- The reason the receipt is unavailable
- Your signature and date — and usually a manager's or approver's countersignature
Why an affidavit alone is often rejected
An affidavit is a claim, not evidence. Many finance teams treat it as acceptable only when paired with independent corroboration that the payment happened. In practice that means a redacted card or bank statement showing the merchant, date and amount — which turns a self-attestation into a self-attestation plus third-party proof.
Attach these where you can
- A redacted statement line showing the posted charge
- The merchant's order or booking confirmation email
- A calendar invite or agenda establishing the business purpose
- A photo of the purchased item, packaging, or event badge
- Written manager approval, if your policy requires it
Frequency limits are real
Most policies cap how often one person can use an affidavit — commonly a small number per year or per quarter — and some require escalating approval after the first. Repeated use is a standard audit flag, so treat the affidavit as a last resort after asking the merchant for a duplicate.
Wording that works
Vague explanations create follow-up questions. Compare "receipt lost" against "Paper receipt was lost in transit from the airport on March 4. Delta flight ATL–SFO, $412.60, booked for the Q1 customer review with Acme Corp. Card statement line attached; airline was unable to reissue an itemized receipt." The second one gets approved without a reply.
