for each of tax tabs we should have more responsive UI after clicking Save button. Currently it seems to wait for API response and then show the loading spinner with save button still enabled.
Save button should be disabled on first click
Save button should be enabled again only after API response
If possible show loading spinner as soon as save button is clicked.
