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.

Where is it in the process, and what happens next?
4 steps remain before this bill could become law.
The record's latest action, on December 2, 2025: Received in the Senate and Read twice and referred to the Committee on Finance.
- Clearing the committees it was referred to, and being scheduled for a floor vote
- Passage by the House
- Passage by the Senate
- The President's signature. If the President vetoes it, two-thirds of both chambers must vote to override.
How likely is it to become law?
Civibrief does not forecast outcomes and this page has no opinion about this one. What the record supports is a base rate, which is a fact about the whole pile, not a prediction about this measure.
In the 118th Congress (2023-24), 274 of the 16,565 bills and joint resolutions introduced became law, about 1.7 percent. That count covers every measure at every stage, including the many that never left committee.
This one is not there yet: 4 steps are still outstanding, listed above.
Has anyone actually voted on it?
No. No roll call in this Congress cites this measure. That is the ordinary outcome: most measures never reach a recorded floor vote, and a committee ends most of them simply by not acting.
A vote is not the only thing that happens to a measure. Hearings, markups, and referrals are all recorded actions, and none of them is a vote of the full chamber.
Who is behind it?
Nathaniel Moran (R-TX) introduced it on September 15, 2025, and 1 member has since signed on as a cosponsor.
They are 1 Democrat.
Cosponsoring is a formal signature on the text. It is not a commitment to vote for the measure, it does not bind anyone's party, and a long list of cosponsors is a measure of attention rather than of prospects.
How long has it been in play?
It was introduced on September 15, 2025, 360 days ago. The most recent recorded action was 282 days ago, on December 2, 2025.
Measures do not carry over. Anything the 119th Congress has not finished by January 3, 2027 dies when the term ends, and has to be introduced again from the start in the next Congress.
Every answer above is assembled from this measure's own record on Congress.gov and from published counts of what Congress has passed before. Civibrief does not predict outcomes and takes no position on any measure.
