What H.R. 5349 does, in plain terms
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.

The TAS Act is procedural reform within Congress's tax and tribunal powers. It expands taxpayer access through equitable tolling, keeps subpoena and contempt powers under judicial control within constitutional limits, and does not restrict rights, seize property, or consolidate power beyond the federal tax forum.

✓ Passes · Enumerated powers
Congress has explicit authority to lay and collect taxes under Article I, Section 8, Clause 1, to constitute tribunals inferior to the Supreme Court under Article I, Section 8, Clause 9, and to make laws necessary and proper for executing those powers under Article I, Section 8, Clause 18. Regulating Tax Court subpoenas, filing deadlines, special trial judges, contempt, and recusal is direct regul… -
✓ Passes · Bill of Rights
No First, Second, Third, Eighth, Ninth, or Tenth Amendment infringement. Subpoena expansion is subject to Tax Court judicial control and relevance limits, satisfying Fourth Amendment reasonableness for compelled production. Contempt authority up to $5,000 and 30 days is within historic petty-offense contempt power and below the Sixth Amendment jury-trial threshold for serious offenses, and recusal… -
✓ Passes · Individual sovereignty
The bill does not restrict speech, belief, labor, property use, or bodily autonomy. It regulates procedure for contesting federal tax liability and, through equitable tolling and preserved district-court review, reduces government barriers to the individual challenging the government. Subpoena and contempt powers are confined to active litigation and judicial oversight, not general regulation of p… -
✓ Passes · Decentralization
Federal taxation and deficiency disputes cannot be resolved by individuals, localities, or states alone. Article I, Section 8, Clause 1 commits federal taxation to Congress, and a uniform federal forum is the minimum necessary level. The bill improves procedures inside that existing federal forum and does not consolidate new substantive power upward or preempt state courts; it expressly preserves … -
✓ Passes · Due process and takings
Enhances procedural due process under the Fifth Amendment: equitable tolling gives fair opportunity to be heard, non-treatment of time-barred dismissal as a decision on the merits preserves subsequent judicial review, and subpoenas remain under neutral judicial supervision. No property is taken without just compensation. Thirty-day contempt power is bounded, requires judicial finding, and remains …
