TAXPAYERS RIGHTS
Whether you file a Form 1040EZ or a complicated corporate return, you will benefit from knowing your rights as a taxpayer and being familiar with the IRS' obligations to protect them. The goal of the Taxpayer Rights Corner is to be your one-stop shop for taxpayer rights information during every step of your interaction with the IRS.
