To withdraw an income tax appeal, the steps depend on where your case sits: at the IRS Independent Office of Appeals, you notify your assigned appeals officer, ideally in writing, that you no longer wish to continue; at the U.S. Tax Court, you file a written motion to dismiss under Rule 53 through the court’s DAWSON electronic filing system. Either way, the IRS’s proposed tax becomes your final bill, and in a Tax Court deficiency case, that outcome is locked in by statute the moment the court dismisses your petition.
Which Stage Is Your Case In
Federal tax disputes move through two levels, and the withdrawal process depends entirely on which one holds your case right now.
The IRS Independent Office of Appeals is administrative. An appeals officer reviews your disagreement with an audit or proposed assessment and tries to settle it through informal conferences by phone, video, or in person.1Internal Revenue Service. What to Expect From the Independent Office of Appeals No courtroom, no judge.
The U.S. Tax Court is judicial. You get there by filing a petition within 90 days of the IRS mailing a notice of deficiency. Once that petition is filed, the court has jurisdiction and the IRS cannot assess or collect the disputed tax until a final decision is entered.2Office of the Law Revision Counsel. 26 USC 6213 – Restrictions Applicable to Deficiencies; Petition to Tax Court That freeze is one of the biggest things you give up by withdrawing.
Withdrawing at IRS Appeals
At the administrative stage, withdrawal is straightforward. There is no dedicated form. You contact your assigned appeals officer and tell them you want to end the process. A phone call is enough to communicate intent, but a short written statement creates a paper trail and avoids any dispute later about what you asked for.
The most common reason to withdraw here is that you’ve decided to accept the IRS’s original proposed changes. Your appeals officer will usually send a closing document reflecting the agreed amounts. If you leave without any agreement, the case simply closes and the IRS proceeds with the assessment it originally proposed.
How you entered Appeals doesn’t change how you leave. Small case requests filed on Form 12203 (for proposed additional tax under $25,000 per period) and formal written protests for larger cases both close the same way: tell your appeals officer you’re done.3Internal Revenue Service. Preparing a Request for Appeals The same is true if you entered through an alternative dispute resolution program like fast-track mediation; those programs are voluntary and either side can stop at any time.4Internal Revenue Service. Appeals Mediation Programs
Withdrawing from Appeals doesn’t automatically end your options. If you received a notice of deficiency and still have days left on the 90-day filing window, you can petition the Tax Court. If that window has closed, or you never received a statutory notice, walking away from Appeals usually means the proposed tax gets assessed.
Withdrawing at the U.S. Tax Court
Ending a Tax Court case is a formal judicial step. To voluntarily end your case, you file a motion to dismiss under Rule 53, which allows dismissal for cause on a party’s motion or on the court’s own initiative.5United States Tax Court. Rule 53 – Motion to Dismiss Your motion must be in writing, state the specific grounds for dismissal, and indicate whether the IRS objects. If you haven’t contacted IRS counsel about the motion, the court assumes there is an objection.6United States Tax Court. Complete Rules of Practice and Procedure – Rule 50
Motions are filed electronically through DAWSON, the Tax Court’s case management system, at ustaxcourt.gov. You’ll need a DAWSON account linked to your case. The motion should include the court’s name, your name as petitioner, the docket number, and a clear statement that you are requesting voluntary dismissal of your petition. If you don’t have a DAWSON account, you can file by mail to the Clerk of the Court at 400 Second Street NW, Washington, DC 20217, though electronic filing is faster and provides immediate confirmation.

How to Prepare the Motion
Before you file, contact the IRS attorney assigned to your case. Every docketed Tax Court case has government counsel handling the other side. Tell them you want to end the case. If you’ve made any progress on the numbers, ask whether a stipulated decision is a better fit than a dismissal. That conversation often determines whether you walk away with the full deficiency or a negotiated figure.
Draft the motion with the required elements: court name (United States Tax Court), your name as petitioner, docket number, grounds for dismissal, and the IRS’s position on the motion.6United States Tax Court. Complete Rules of Practice and Procedure – Rule 50 If you’re representing yourself, sign it personally. If you have counsel, one attorney’s signature is sufficient.
After you file, the court reviews the motion and issues an order. Monitor your case in DAWSON for status updates. Once the decision is entered and the appeal period passes, the decision becomes final and the IRS can proceed with assessment and collection.
The Deficiency Trap: Why Tax Court Dismissal Locks In the Full Bill
This is the single most important thing to understand before withdrawing a Tax Court petition.
In a deficiency case, if the court dismisses your petition for any reason other than lack of jurisdiction, the court must enter a decision sustaining the full deficiency the IRS originally proposed. Under IRC 7459(d), the court enters an order specifying the deficiency amount determined by the IRS, and that amount becomes the final tax due.8Office of the Law Revision Counsel. 26 USC 7459 – Reports and Decisions The IRS’s internal guidance states it plainly: “A taxpayer may not withdraw his petition to avoid the entry of decision.”9Internal Revenue Service. IRM 35.8.1 General Requirements for Tax Court Decisions
Under Rule 123(d), a decision entered after dismissal (other than for lack of jurisdiction) operates as an adjudication on the merits.10United States Tax Court. Complete Rules of Practice and Procedure – Rule 123 The same dispute cannot be relitigated anywhere else. The practical effect is the same as losing at trial on every issue.
If the IRS said you owe $50,000 in additional tax and you file a bare motion to dismiss, the court enters a $50,000 deficiency, even if you had strong arguments that could have reduced it.
Stipulated Decision Is Usually the Better Exit
When both sides agree on how a Tax Court case should end, they file a stipulated decision. The document typically opens “Pursuant to the stipulation of the parties…” and it incorporates the agreed facts and amounts.9Internal Revenue Service. IRM 35.8.1 General Requirements for Tax Court Decisions A stipulated decision also precludes either side from appealing, so it’s truly final.
The difference matters when you’ve settled some issues but not others. A stipulated decision captures those partial wins. A straight dismissal throws them away and gives the IRS its full opening number. If you’ve made any progress with IRS counsel, ask for a stipulated decision instead of filing a motion to dismiss. If you genuinely want to accept the IRS’s full proposed amount, the two paths reach the same number, but stipulation is cleaner because the terms are explicit.
Can You Refile After Withdrawing?
In most deficiency cases, no. The 90-day window to petition the Tax Court starts running when the IRS mails your notice of deficiency, and the court cannot extend that deadline.11United States Tax Court. Guidance for Petitioners – Starting a Case By the time you withdraw a petition that has been pending for months, that window closed long ago. And because dismissal in a deficiency case operates as an adjudication on the merits, the same dispute cannot be raised in another forum.
Collection due process (CDP) cases work slightly differently. A voluntary dismissal in a CDP case is technically “without prejudice,” but the ability to refile is extremely limited. The 30-day filing period for CDP petitions has already expired, and getting back into court would require proving equitable tolling, which courts grant sparingly and which is particularly hard to justify when you asked for the dismissal.
Treat withdrawal as a one-way door.
How Withdrawal Restarts the Collection Clock
Filing a Tax Court petition freezes more than assessment. It also pauses the 10-year collection statute of limitations. Under IRC 6503(a), that period is suspended from the time the notice of deficiency is mailed until the Tax Court’s decision becomes final, plus an additional 60 days.12Office of the Law Revision Counsel. 26 USC 6503 – Suspension of Running of Period of Limitation
When you withdraw and the court enters its decision, that decision becomes final after the 90-day appeal period expires. At that point the collection clock resumes, and the IRS has the remainder of its 10 years from the date of assessment to collect through levies or court proceedings. Time spent in Tax Court doesn’t count against that window.13Taxpayer Advocate Service. Collection Statute Expiration Date (CSED) If your case was pending for two years, the IRS gets back roughly two additional years of collection time. For taxpayers who were near the end of the statute, that shift is significant.
When Withdrawing Is the Right Call
There are legitimate reasons to end a tax appeal early, even with all of the above in mind.
- You’ve reached a settlement. In that case, formalize it as a stipulated decision, not a bare dismissal. The withdrawal of your dispute is built into the settlement paperwork.
- The cost of litigation exceeds the tax at stake. Document production, legal fees, and time away from work can outweigh the amount in dispute.
- Your legal position has weakened. New case law, a failed argument at Appeals, or an unavailable witness can erode a case that once looked strong. Continuing only adds interest.
- You want a different resolution path. Some taxpayers withdraw a petition to pursue an offer in compromise or an installment agreement. An offer in compromise doesn’t automatically require withdrawal of a pending petition, but tax debts under the court’s jurisdiction may be handled differently during the offer evaluation.14Internal Revenue Service. Form 656 Booklet – Offer in Compromise
One boundary worth flagging: if you never filed a Tax Court petition and the 90-day letter is still open, “withdrawing” isn’t really what you’re doing. You’d sign Form 870, which waives the restrictions on assessment and lets the IRS proceed immediately. That path preserves the option to pay and then sue for a refund in federal district court or the Court of Federal Claims, but not in Tax Court.15Internal Revenue Service. Form 870 – Waiver of Restrictions on Assessment and Collection of Deficiency
Don’t Just Stop Showing Up
Some taxpayers don’t formally withdraw. They skip hearings, ignore correspondence, and let the case sit. This is almost always worse than an intentional withdrawal.
Under Rule 123(b), the Tax Court can dismiss a case on its own initiative for failure to prosecute.10United States Tax Court. Complete Rules of Practice and Procedure – Rule 123 The result is the same as a voluntary dismissal, meaning the full deficiency is entered, but you lose the chance to negotiate or control the timing. If the IRS prepared for a trial you never attended, the court also has discretion to impose terms and conditions on the dismissal.
If you’re going to end a case, end it deliberately. File the motion, coordinate with IRS counsel, and close it on your terms.
