In December 2020, the United States Tax Court will be launching DAWSON (Docket Access Within a Secure Online Network), the Court’s new case management system. The Court expects DAWSON to be active no later than December 28, 2020. Beginning at 5:00 PM Eastern Time on November 20, 2020, the current e-filing system will become inaccessible and all electronic files will become read-only. In early December, those with current access to the old system will receive a new user name and temporary password for DAWSON and must promptly act within 7 days after notice, in order to avoid an interruption to access to your electronic case records.
