Here is information I received from my Treasurer training and also a letter from Toastmasters Int.
“Our web feedback team mentioned to me that you needed some assistance with the 990n. Are you looking for information about how to file? If so please be aware that Toastmasters International files the federal 990n on behalf of all US Toastmasters clubs.
