What are the penalties for missing a quarterly payment due date?
Technically there is not a specific penalty for not making your estimated payment. Instead, you will be charged an interest rate for the money that should have been paid to the IRS. If you have only missed the deadline by a few days or weeks then you will most likely not incur a penalty. However, if you go the whole year without making any quarterly payments then you should seek the help of a tax professional to calculate the amount of interest you owe.
