A missing receipt affidavit is a signed, sworn statement you use to document a business purchase when the original receipt is lost, was never issued, or has been destroyed. You write down the vendor, date, amount, what you bought, and why the receipt is gone, then sign under penalty of perjury and hand it to whoever needs proof of the expense: your employer’s accounting team, your own tax file, or an auditor. The form stands in for the receipt, and because you’re swearing to it, it carries real legal weight.
When You Actually Need One
The usual trigger is an expense report. You paid for something on a work trip or for a job-related purchase, the receipt is gone, and your employer’s policy still requires documentation. The affidavit fills that gap. Universities, government agencies, and private companies all keep versions of the form on hand for exactly this situation. Cal Poly Pomona’s travel policy, for example, requires the affidavit when “an original, itemized receipt cannot be obtained” and the traveler “has exhausted all measures to obtain a duplicate.”1California State Polytechnic University, Pomona.

Self-employed taxpayers hit the same problem at tax time. The IRS requires you to substantiate deductions for travel, gifts, and listed property with adequate records.2Office of the Law Revision Counsel. 26 U.S. Code 274 – Disallowance of Certain Entertainment, Etc., Expenses When the paper receipt is gone, a sworn written reconstruction backed by bank or card records can serve as secondary evidence, though the burden of proving the expense was real stays with you.3Internal Revenue Service. Representing the Taxpayer Without Records
Before you fill anything out, check whether the IRS even requires a receipt for the expense. Publication 463 waives the documentary evidence requirement for most business expenses under $75 and for transportation charges where a receipt isn’t readily available.4Internal Revenue Service. Publication 463 – Travel, Gift, and Car Expenses The $75 threshold comes from Treasury Regulation § 1.274-5(c)(2)(iii).5eCFR. 26 CFR 1.274-5 – Substantiation Requirements Lodging is the exception you can’t ignore: hotel and other lodging expenses require documentary evidence regardless of the amount, so a $55 motel gets the same treatment as a $500 hotel bill. Note that the $75 waiver relaxes the format of your documentation, not the duty to record the payee, amount, proof of payment, date, and business purpose in some form.6Internal Revenue Service. What Kind of Records Should I Keep
One other boundary worth naming: your employer’s policy may require an affidavit for amounts the IRS wouldn’t. The IRS rules set a floor for tax records, not a ceiling on what your company can ask for.
Information to Gather First
Pull together everything you can reconstruct about the transaction before you sit down with the form. Standard fields across most versions include:
- Vendor name and location — the business where you made the purchase.
- Exact date of purchase, not an approximation.
- Total dollar amount, including tax and tip if applicable.
- A specific description of what you bought. “Office supplies” is weaker than “printer toner cartridges and copy paper.”
- Business purpose — a client meeting, a work trip, restocking the office.
- Why the receipt is missing: lost, discarded, never issued, or destroyed. Most forms have checkboxes.7Smith College. Missing Receipt Affidavit
- The steps you took to get a duplicate from the vendor before resorting to the affidavit, if the form asks.
Your employer’s accounting department or HR portal usually supplies the specific form. If you’re self-employed or need a general template, legal document sites and office supply stores carry blanks with the same core fields.
How to Fill Out the Form
Start with the hard numbers: vendor, date, and amount. These need to match your bank or card statement exactly, because reviewers cross-reference them. A few dollars off creates a delay or a rejection. If you paid cash and have no bank record, say so on the form.
The description field is where most people undercook it. Write enough that a reviewer who doesn’t know your work can see why the expense was necessary. “Lunch” tells them nothing. “Working lunch with client during vendor site visit, two meals” gives them what they need. The IRS looks for a description that “show[s] the amount was for a business expense,” and your employer’s auditors think the same way.6Internal Revenue Service. What Kind of Records Should I Keep
For the reason the receipt is missing, be direct. “Receipt was lost during travel” or “vendor did not provide a receipt at time of purchase” is enough. No narrative required. Some organizations also require a supervisor’s signature next to yours confirming the expense fits your job responsibilities.8Vassar College. Missing Receipt Affidavit
Back It Up with Supporting Evidence
An affidavit alone is a sworn statement. An affidavit with a card statement attached is a sworn statement backed by independent proof, and that combination is far more persuasive to a reviewer or auditor. The IRS itself notes that “a combination of supporting documents may be needed to substantiate all elements of the expense.”6Internal Revenue Service. What Kind of Records Should I Keep
Attach whatever secondary records you can find:
- A credit or debit card statement showing vendor, date, and amount.
- A bank transaction record for debit purchases or ATM withdrawals tied to the expense.
- Email confirmations for online orders, hotel bookings, or conference registrations. These often outlive the paper receipt.
- Calendar entries or travel itineraries. They don’t prove the dollar amount, but they corroborate the date and the business purpose.
For companies that use expense management platforms, the card feed itself becomes evidence, because it automatically captures the vendor and amount from the transaction. Combined with your signed affidavit, that often satisfies internal audit requirements without anything further.
Signing the Affidavit
The signature line is what gives the document its legal force. By signing, you’re declaring under penalty of perjury that the information is true. Federal perjury law sets the maximum penalty at a fine and up to five years in prison.9Office of the Law Revision Counsel. 18 U.S. Code 1621 – Perjury Generally That ceiling is aimed at intentional false statements, not an honest mistake about a lunch tab. Still, the penalty exists to make sure people don’t inflate amounts or fabricate expenses.
Handwritten and Electronic Signatures
Most employers accept either. Under the federal E-SIGN Act, an electronic signature carries the same legal validity as ink on paper for transactions affecting interstate commerce. It “may not be denied legal effect, validity, or enforceability solely because it is in electronic form.”10Office of the Law Revision Counsel. 15 U.S. Code 7001 – General Rule of Validity When you click “I certify” or type your name into a signature field in Concur or Expensify, that counts.
When You’ll Need a Notary
Some situations require notarization, which adds identity verification to the signature. A notary public will confirm your identity using a current, unexpired government photo ID, typically a driver’s license, passport, or state ID card, then witness your signature and apply a seal.11Commonwealth of Pennsylvania. Powers of a Notary Public Notary fees for a single acknowledgment generally run from $2 to $15 depending on the state. Most routine employer reimbursement affidavits don’t require notarization, so check your company’s policy before making the trip.
Where to Send It
For employer reimbursements, most companies with digital expense systems let you upload the signed affidavit as a PDF or image alongside the expense report. If your organization is still paper-based, deliver or mail the signed original to accounting. Keep a copy for yourself either way, and if the platform has a status tracker, use it. Following up within your company’s normal reimbursement cycle keeps the form from getting stuck.
For tax purposes, you don’t send the affidavit to the IRS with your return. You keep it in your records with the supporting evidence you gathered. If the IRS questions the deduction during an audit, that packet is what you produce.
How Long to Keep the Records
The IRS generally expects you to keep records supporting a tax return for three years from the filing date, which is the standard audit window.12Internal Revenue Service. How Long Should I Keep Records For employment tax records, the IRS recommends at least four years.13Internal Revenue Service.

If you ever have to reconstruct an expense history, having everything in one place beats hunting through scattered files.
