Rules for Form 1040

IRS Form 1040 is often called the "long form," because it is designed to account for every option in filing your federal income taxes. Unlike Form 1040EZ, which is a simplified version available to certain groups of taxpayers, the standard 1040 and its attachments can be complicated and time-consuming.
