As of June 2019 there is now an online form called "Confidential Tithing Report", linked in from the Stake Conferences dashboard (
https://galt.churchofjesuschrist.org/dashboard).
Step 1 is for the stake clerk or a member of the stake presidency to enter the occupation for each stake leader / bishop. So far so good, but there is no place to enter the tithing, and no mention of how that is done.
Step 2,
only the stake president can see the tithing status dropdown and select "Full", "Part", or "Non". The clerk or others see nothing there and no explanation (that's the confusing part). This was confusing and needs some kind of message, or perhaps the column to still be there (not revealing the status) but with a message saying only the stake president can see this. It was only by viewing the source code that I could tell the column was in fact there, but only the stake president would see it.
Thanks for putting it online! That is much appreciated, as are all of the time saving efforts of the tech team. Just a small interface change will remove the confusion.
