The IRS will not allow you to wait to pay your taxes on the last day of filing or late in the year ... it is a "pay as you go" system and that is how penalties are accrued. If your income was earned unevenly during the year and the program says you owe a penalty then you can use the annualized method to reduce or negate the penalty ... for $42 it is probably not worth the effort especially if you did not keep excellent and detailed quarterly records.
