Receipts
How do I prove a business expense without a receipt?

Short answer
Without a receipt, reconstruct the record: use your bank or card statement, calendar entries, emails, and a written note of the business purpose to substantiate the expense. Going forward, capture receipts automatically so you are never in this spot again.
A card or bank statement shows the amount, date, and merchant, which is a strong start. Pair it with supporting context: the email confirmation, a calendar event, a photo, or a short written note explaining who was there and why the expense was for business. The more corroborating detail, the better it holds up.
The IRS generally expects you to substantiate business expenses, and some categories (like travel and meals) have specific documentation expectations. Reconstructed records can work, but they are weaker than the original receipt, so check current IRS guidance for what is required for your expense type.
The real fix is prevention. Mylo keeps a digital copy of every receipt by capturing them from your email, connected store accounts, your camera roll, and card matches, and it categorizes each one, so you stay audit-ready and rarely have to reconstruct anything.
How it works in Mylo
- Pull the bank or card statement line that shows the amount, date, and merchant.
- Gather supporting evidence: email confirmations, calendar entries, photos, or vendor records.
- Write down the business purpose and, for meals, who attended, while you still remember.
- Keep these together with the transaction so the trail is easy to follow later.
- Check current IRS guidance for the documentation your expense category requires.
Best practices
- Log the business purpose immediately; details fade fast after the fact.
- Match every charge to a receipt monthly so gaps surface while they are fixable.
- Let Mylo capture receipts automatically from email, store accounts, and card matches, so the original is saved before it can go missing.
- When in doubt about substantiation, confirm with your accountant or IRS guidance.
