If I have scanned a receipt to the app and it is under the reviewed section. Do I still need to hang onto the paper copy for tax purposes or is my uploaded copy enough?

Hi there, @hayleyrobynking. 

You can keep either your paper or the uploaded copy. But specific recommendations would depend on your specific needs. 

QuickBooks Self-Employed helps you with record-keeping, and receipts at the individual transaction:

• Automatically stores info about the date, amount, and place (payee/supplier)
• Gives you the ability to add notes (particularly useful for meal/entertainment expenses)
• Lets you attach a receipt or document

This allows you to keep everything in one place, add notes, and retrieve receipts quickly. QuickBooks Self-Employed also makes smart suggestions for categorizing your expenses for your Schedule C.

If you have specific questions about receipts and record-keeping for tax purposes, we recommend you talk with your accountant or a tax professional.

For additional reference, I've attached some articles you can use to get receipts from your email, as well as how to create a new transaction directly from an image of your receipt: 

• Enter receipts on your QuickBooks Self-Employed mobile app

• Receipt Forwarding Feature

Let me know in the comment section below if you have any other questions. Have a great day ahead.
