This was not a future late payment it was for 2022 form 1040 ....so everyhing was a known ...normally Turbo Tax just says ...you owe X and it adds it to the ballance of what you need to pay...same thing for the 2022 but the IRS said it was mis calculated....so I was wondering if there was a programing error in the TURBO TAX program and was wondering if anyone else experienced this ??
It's just one of those things that, when any tax program calculates a penalty, it's only an estimate and the IRS always has final say. It should not be too far off. The biggest reason for a difference is that one of the late fees is based on being late "any part of a month". So if the due date was April 17, you are one month late if they get a payment on May 17, but 2 months late if they receive the payment on the 18th. (And the same is true for each quarterly estimated payment. Best to pay those a few days early.)
The other thing I recommend is to decline to include a penalty and wait for the IRS to bill you. That way it will be the final figure. That also gives you a chance to apply for a waiver of the penalty, if it is your first time owing a penalty or you have a reasonable cause to ask for relief. It's harder to apply for relief if you paid the penalty when you filed.
