You know, don't push the button, don't push the button, don't push the button, and then some socko finish. I was pleasantly surprised by how the book bobs and weaves and is a lot more active and entertaining that just that. MILD SPOILER, so don't tell your four year old.
The late payment penalty applies to any portion of your federal tax that remains unpaid as of the due date, typically the tax filing date. The IRS imposes a failure-to-pay penalty of one half of one percent for each month or part of a month that the tax goes unpaid.
The per person penalty amount is $695 per adult. For children under the age of 18, it is half that amount, $347.50, per child. The maximum due is $2,085. You are required to pay the fee when you file your federal tax return for the year you didn't have health insurance coverage. This is referred to as your individual responsibility payment.
