Overriding the penalty is not allowed for e-filing and would cause alot of work on the preparers. The taxpayer may have an underpayment penalty for not making enough payments through the 1st 3 quarters but should not be punished for not making the 4th. Perhaps at least allow us to override the 4th qtr interest rates? That should be an easy programming fix although would not fix in all situations. I have many clients that deferred significant payments in the 4th quarter. This will draw a slew of notices. Please fix Lacerte!!! I don't understand why you are not making programming changes for a law change that affects so many taxpayers!!!
