When I scan a Receipt, what part of amount can be used as a business expense - full amount or just HST?

Hi mailshine94-gmai,

Welcome to the QuickBooks Community! QuickBooks is a versatile program that enables you to get your work done faster. I'll be happy to help you with your receipt.

When scanning a receipt for business expenses in QuickBooks Online Canada, you can use the full amount of the expense, including both the HST and the base cost. The CRA accepts digital copies of receipts, as long as they capture all the information on the front and back of the receipt. When scanning your paper receipts or taking photos of them, make sure the digital copy is legible and complete. 

Here is a couple articles for you:
