I have 50 completed S corp returns with that form, so we're sitting in a waiting pattern on all of those clients - S corp and personal. Spoke to Lacerte last week and they told us the same as the website - it'll be released when it's released. I'm not sure how the S corp Form 8283 is any different than the individual 8283, which was released in the end of January by the IRS. 

Message me if you get any movement! 🙂
