taxmap/pubs/p505-000.htm#en_us_publink1000194308Introduction

The federal income tax is a pay-as-you-go tax. You must pay the tax as you earn or receive income during the year. There are two ways to pay as you go. This publication explains both of these methods. It also explains how to take credit on your return for the tax that was withheld and for your estimated tax payments.
If you did not pay enough tax during the year, either through withholding or by making estimated tax payments, you may have to pay a penalty. Generally, the IRS can figure this penalty for you. This underpayment penalty, and the exceptions to it, are discussed in chapter 4.
