United States Tax Court

When the Commissioner of Internal Revenue has determined a tax deficiency, the taxpayer may dispute the deficiency in the Tax Court before paying any disputed amount. The Tax Court’s jurisdiction also includes the authority to redetermine transferee liability, make certain types of declaratory judgments, adjust partnership items, order abatement of interest, award administrative and litigation costs, redetermine worker classification, determine relief from joint and several liability on a joint return, review certain collection actions, and review awards to whistleblowers who provide information to the Commissioner of Internal Revenue on or after December 20, 2006.
