Key: what the circles and colors mean

Each circle is a bill. The ring fills as it moves through Congress:

IntroducedPassed one chamberPassed both chambersBecame law (gold)Resolution agreed to (full, dark)Failed or vetoed (gray)

Under the number: the Yea · Nay count of its final (or latest) recorded vote. On a member's page, the small badge is how that member voted: Y Yea / Aye, N Nay / No, P Present, – Not voting.

Gold and violet are only for Yea and Nay; they never mean a party. A member's party is the letter on their photo.

Passed the House and the Senate without a recorded vote. It passed by voice vote or unanimous consent, which don't record how each member voted. Its text can still change before it becomes law.

Tax Court Improvement Act

This bill expands the authority of the U.S. Tax Court to issue subpoenas, authorizes the Tax Court to extend certain petition deadlines, and makes other changes related to Tax Court procedures.

The bill authorizes the Tax Court to issue subpoenas compelling the production of documents and other items from a litigant or witness for evidentiary or discovery purposes (whether or not it is in connection with a scheduled hearing). (Under current law, the Tax Court may issue subpoenas only to compel the attendance and testimony of witnesses and the production of evidence at a scheduled hearing or deposition.)

The bill authorizes the Tax Court to extend (or toll) the deadline to file a Tax Court petition contesting an Internal Revenue Service (IRS) deficiency notice if it is equitable to do so (known as equitable tolling). Further, under the bill, the dismissal of a petition contesting an IRS deficiency notice because the petition is not filed before the deadline and equitable tolling is denied is not treated as a decision of the Tax Court. This allows a subsequent claim to be filed in U.S. district court if certain conditions are met.

The bill also

  • expands the type of Tax Court proceedings for which special trial judges may be appointed,
  • authorizes Tax Court special trial judges to impose fines up to $5,000 and up to 30 days in jail for contempt of court, and
  • requires Tax Court judges and special trial judges to recuse themselves in certain circumstances.
