Tip: Write the docket number on every page so the Clerk's Office can attach your fax to the correct case. Since the Tax Court moved filing onto DAWSON, fax is best treated as a backup for correspondence rather than a route for petitions or motions, which the Rules expect electronically. Confirm with the Clerk's Office at 202-521-0011 what they will accept before sending a time-sensitive document, and keep the Send FAX Mail confirmation as evidence of the transmission date.
