Hi ian_nicholls-sky, thanks for joining the Community
We're aware that some customers are receiving the following error when snapping receipts on the QB iOS app:
"Validation failed. We’re sorry, QuickBooks encountered an error while calculating tax. Try reselecting the tax rate or reentering the product/service item and saving the form again."
Please confirm if this is the same error that you're experiencing so that we can add you to our investigation for updates.
