It won’t allow me to edit my receipts that Iv taken pictures of, it keeps saying the tax is wrong even it’s not

Hello and welcome to the Community, pryce1-hotmail-c

We're aware that some iOS users are seeing the following message when snapping receipts on the app: 

"Validation failed. Were 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 issue that you are experience so that we can add you to our investigation for updates.
