For those who pay estimated taxes, b&py's last entry gets really close. Not that I like it, but I understand ... The IRS will penalize you if you underpay throughout the year, expecting you to pay 25% of your total 4 times and on-time, to ensure timely cash flow into the federal coffers. That is, you can't wait to the last quarter to pay all your taxes for the year unless that is when all your income occurs. So, Parts III or IV are used to make sure you don't underpay through the course of the year, necessitating filing the form. Tricking the program in this situation gets you to the same monetary outcome, assuming you didn't underpay through the year, but an audit would reveal that the correct forms were not completed.
You'd like to think that if Part II Box A was checked in addition to either Boxes B, C, or D that the IRS software would ignore it, but apparently not. It seems that between the TT and IRS software, the 85% Waiver annotation isn't recognized or the IRS software gets confused when more than one box is checked. If the latter, b&py's fix would seem to be spot-on and based on the purpose stated above, seems the most appropriate fix anyway. Based on the error message, it would appear the former and would occur whether someone paid estimated taxes or not. But that's what the programmers should be figuring out ...
Now by 3/8 !!! I am beyond disappointed with TT. I signed up for the notifications for the fix. While the initial 2/21 e-mail says the date is subject to change from 3/1, I would have expected the courtesy of an update from the company we all paid for this service, rather than have to search for updates from the users. Thanks to those that provided the update!
