A regular Tax Court decision can be appealed to a United States Court of Appeals. For Florida individuals, that is generally the Eleventh Circuit in Atlanta. An appeal is not a new trial. It is a review of whether the Tax Court got the law right and whether its factual findings hold up under a deferential standard.

Here is how the process works and what to weigh before you file.

Which decisions can be appealed

IRC 7482(a)(1) gives the courts of appeals exclusive jurisdiction to review Tax Court decisions, except as provided in 28 U.S.C. 1254 for Supreme Court review, in the same manner and to the same extent as decisions of district courts in civil actions tried without a jury.

The major exception is small tax cases. IRC 7463(b) says S case decisions shall not be reviewed in any other court. If you elected small case procedures, there is no appeal.

Where the appeal goes

IRC 7482(b) sets venue based on the petitioner:

  • For an individual seeking redetermination of tax, the circuit of the petitioner's legal residence.
  • For a corporation, the circuit of its principal place of business or principal office.
  • For an innocent spouse petition under IRC 6015(e), the petitioner's legal residence.
  • For a CDP case under IRC 6320 or 6330, the individual's legal residence, or for an entity, its principal place of business or office.

The statute measures residence as of the time the petition was filed. A Florida resident at filing appeals to the Eleventh Circuit even if they later move. If no subparagraph applies, the D.C. Circuit hears the appeal. IRC 7482(b)(2) also allows the parties to designate a circuit by written stipulation.

The Golsen rule

Because appeals go to different circuits, the Tax Court follows the law of the circuit to which the case is appealable when that circuit has squarely decided the issue. That principle comes from Golsen v. Commissioner, 54 T.C. 742 (1970). For a Florida taxpayer, Eleventh Circuit precedent effectively governs the Tax Court's decision on issues the Eleventh Circuit has decided.

That matters before trial as much as after it. When you evaluate hazards of litigation in settlement, the controlling circuit law is part of the analysis.

The 90-day deadline

IRC 7483 requires the notice of appeal to be filed with the clerk of the Tax Court within 90 days after the decision is entered. If one party files a timely notice, any other party may file a notice within 120 days after entry. Tax Court Rule 190(a) repeats the rule, adds that the notice must be filed with the required filing fee, points to Rules 13 and 14 of the Federal Rules of Appellate Procedure, and refers to Form 17 as a suggested notice of appeal.

Note where it is filed: with the Tax Court, not the court of appeals. Count from entry of the decision, not from the opinion. The opinion and decision can be months apart when a Rule 155 computation is involved.

A timely motion to vacate or revise the decision under Tax Court Rule 162 affects when the appeal period runs under the Federal Rules of Appellate Procedure. Coordinate post-decision motions with appeal timing carefully.

Standards of review

Because IRC 7482(a)(1) treats Tax Court decisions like district court bench trials, the familiar standards apply. Legal conclusions are reviewed de novo. Findings of fact are reviewed for clear error, which is deferential. Credibility determinations are especially hard to overturn.

Here's the part most people miss: most tax cases are won or lost on the facts, and facts are where appellate courts defer most. An appeal is strongest when the Tax Court applied the wrong legal standard, misread a statute or regulation, or ignored binding circuit precedent. An appeal that argues the judge should have believed your witness is usually an expensive way to lose again.

Staying assessment and collection: the bond

Filing a notice of appeal does not stop the IRS from assessing and collecting. IRC 7485(a) says review does not stay assessment or collection unless the taxpayer, on or before filing the notice of appeal, files a bond with the Tax Court in an amount fixed by the Court, not exceeding double the amount of the portion of the deficiency appealed, with approved surety, or has filed a jeopardy bond.

The bond requirement is a major practical consideration. If you cannot post a bond, the IRS can assess and collect while the appeal is pending. If you pay and then win on appeal, you are entitled to a refund with interest, but the cash is gone in the meantime.

Appeals in CDP and other non-deficiency cases

The same appeal rules apply to most Tax Court decisions beyond deficiency cases, including Collection Due Process determinations and innocent spouse cases, with venue set by IRC 7482(b)(1)(F) and (G). In CDP appeals, the standard of review on collection issues carries through: the court of appeals reviews whether the Tax Court correctly applied the abuse of discretion standard to the Appeals determination. Arguments not raised at the CDP hearing, and therefore not considered by the Tax Court, are rarely revived on appeal. See Tax Court review of CDP determinations.

The IRS can appeal too

If you win in Tax Court, the IRS can appeal. The same 90-day rule applies, and your cross-appeal window is 120 days. If you won on some issues and lost on others, think about whether a cross-appeal makes sense if the government appeals.

What an appeal looks like

  1. Notice of appeal and fee filed with the Tax Court within 90 days.
  2. Bond filed if you want to stay assessment and collection.
  3. The record, including transcripts and exhibits, is transmitted to the court of appeals.
  4. Opening brief, answering brief, and reply brief under the court of appeals' rules and schedule.
  5. Oral argument, if the court grants it.
  6. A decision affirming, reversing, or remanding.

After the court of appeals rules, a party may petition the Supreme Court for certiorari. IRC 7481(a)(2) and (3) explain when the Tax Court decision becomes final in each scenario.

Deciding whether to appeal

  • Is there a legal error, not just an unfavorable factual finding?
  • What does Eleventh Circuit precedent say on the issue?
  • Can you post a bond, or will collection proceed during the appeal?
  • Does the issue recur in other years, making precedent valuable?
  • What is the cost compared with the amount at stake?

The 90-day appeal clock starts when the decision is entered, and the bond question needs an answer before the notice is filed. If you have a Tax Court decision you think is wrong, call (813) 229-7100. Let's talk.
