Hi Bevy1,
We're aware of the situation, and our engineers are working to restore full functionality as soon as possible. In the meantime, you'll want to log out and back in or try a different browser to restore the missing sales tax column.
For any transactions created yesterday between 8:45–11:15 AM PT, you'll also need to open and re-save them to update the tax amounts.
If the issue persists, please reach out to our QuickBooks Online Live Support team for immediate assistance.
