Hi AJohnson7,
Welcome to Community! It's important that your sales tax is calculated and recorded accurately in QuickBooks Online. Having a difference in HST on your forms can be concerning. I'd be glad to help!
To ensure your sales tax is accurate, I suggest reviewing how the HST has been setup. You can check the sales tax rates by going to Taxes > Sales Tax > Manage Sales Tax. Although you can't edit a current sales tax rate, you can set up a new sales tax code. If the issue persists, I recommend contacting us outside of Community for further review and possible investigation from our end.
