The United States Tax Court is a prepayment forum in which taxpayers may challenge an IRS notice of deficiency before paying the disputed tax. Once the trial concludes, the case moves into the post-trial phase. At this stage, the focus shifts to the judge’s evaluation of the record, the issuance of an opinion, and the entry of a formal decision. The court also provides procedural guidance to petitioners regarding the steps that they may follow.
At the close of the trial, the judge may direct the parties to submit post-trial briefs. These filings typically contain proposed findings of fact and legal arguments based on the evidence presented at trial. In some cases, the court may also permit oral argument or request memoranda addressing particular legal authorities. The judge generally informs the parties of these requirements during the trial or immediately after it concludes.
There is no fixed timetable for the judge to issue a decision. The opinion is prepared after the judge reviews the testimony, exhibits, and arguments presented during the trial.
Occasionally, the judge may deliver an oral bench opinion during the trial session, particularly in regular cases or in small tax cases designated under the court’s simplified procedures. When this occurs, a transcript of the bench opinion is typically made available within a few weeks through the court’s electronic docket system.
The trial may conclude in various cities across the United States, where the judge may issue a written opinion. In that case, the judge returns to Washington, D.C., to review the testimony and exhibits and prepare a detailed written opinion.
The Tax Court issues several types of opinions:
New opinions are typically posted on the court’s website each day after 3.30 pm Eastern time. Parties also receive copies through mail or electronic notification. The opinion explains the court’s reasoning and conclusions on the issues presented.
After issuing its opinion, the court enters a formal decision reflecting the outcome of the case. The decision represents the court’s final judicial determination resolving the dispute and is distinct from the explanatory opinion itself. The entered decision is transmitted to the parties and recorded on the court’s docket.
In some cases, the opinion resolves the legal issues but does not specify the precise dollar amount of a deficiency or overpayment. When that occurs, the court may direct the parties to submit computations under Tax Court Rule 155. The parties, often working together, calculate the correct tax liability consistent with the court’s findings. If the parties cannot agree, each may submit its own computation within the time period set by the court, commonly about 90 days. The court then reviews the submissions, resolves any differences, and enters a decision incorporating the final amounts. These computations are limited to implementing the court’s opinion and may not raise new issues or revisit matters already decided.
In regular cases, a party may file a motion for reconsideration within 30 days after the opinion is served. Such motions may explain the specific grounds for disagreement and demonstrate why reconsideration is warranted. The motion is ordinarily decided by the same judge who issued the opinion. Reconsideration is granted only in limited circumstances, typically where a substantial error or unusual circumstance is shown. Generally, small tax cases do not permit appeals, and post-decision relief is correspondingly limited.
The availability of appellate review depends on the type of case. Decisions in small tax (“S”) cases are final and cannot be appealed by either party. In regular cases, however, a decision may be appealed to the appropriate United States Court of Appeals. This is generally the circuit where the taxpayer resided or maintained a principal place of business when the petition was filed.
A notice of appeal may be filed with the Tax Court within 90 days after the decision is entered, or within 120 days if the IRS files the first notice of appeal. Filing fees apply, and the procedures governing appeals are set out in the Tax Court’s appellate rules.
After trial, the court notifies the parties of opinions and decisions through mail or electronic service, and the documents are also posted on the court’s docket system. If a petitioner disagrees with the outcome, the available options are limited to reconsideration motions in regular cases or, where permitted, appeal.
Transcripts of trial proceedings should generally be ordered from the private court reporter and paid for by the parties, particularly if they are needed for post-trial briefing or appeal. In limited circumstances, self-represented petitioners may request that the court cover transcript costs, typically where financial hardship exists, and the transcript is necessary for briefing. Copies of court documents can also be obtained through the court’s records office or electronically by registered users.
In certain cases, a taxpayer who prevails may seek reimbursement of litigation costs and attorney’s fees from the IRS if the government’s position was not substantially justified. As with any litigation, the final outcome may vary: the taxpayer may prevail entirely or in part, the IRS may prevail, or the matter may be resolved through other procedural outcomes consistent with the court’s decision.
