The usual filing deadline is 90 days from the notice date; certain notices involving an address outside the United States use 150 days. The Tax Court cannot extend this statutory deadline, so read the notice’s printed last day and start preparing immediately.
This guide explains how to verify the notice, file through DAWSON or on paper, protect sensitive information, choose between regular and small tax case procedures, and understand what follows. It is general procedural information, not an assessment of your notice, deadline, or tax arguments.

What a Tax Court petition does
A statutory notice of deficiency is the document that opens the prepayment route to Tax Court. The IRS describes it as the notice that gives you a right to challenge a proposed adjustment in Tax Court before paying. In general, you cannot begin a deficiency case in Tax Court before the IRS issues that notice. See the IRS explanations of CP3219N notices and the Right to Finality.
Filing a timely petition generally postpones payment of the disputed deficiency while the case is pending, and the IRS generally may not try to collect the amount in dispute during that case. Those protections concern the disputed deficiency; they do not automatically resolve other tax debts, collection actions, or exceptions that may apply to your circumstances.
First, make sure the letter is a statutory notice of deficiency
Do not treat every IRS letter as a Tax Court notice. An examination letter, proposed adjustment, balance-due bill, math-error notice, or collection notice can have a different response process. The document should identify itself as a statutory notice of deficiency and state the last day to file a petition. A CP3219N is one example of a notice that can provide this route.
Check the notice itself
- Locate the mailing date and the “last day to file a petition” or equivalent deadline language.
- Read the notice number and description of the proposed deficiency, additions to tax, and penalties.
- Keep every page and envelope or delivery record. The notice copy is used in the filing process.
If you cannot tell whether your document is a statutory notice, do not assume that an IRS phone call or an appeal request substitutes for a petition. Compare the letter with the IRS’s CP3219N guidance and the Tax Court’s starting-a-case instructions, and obtain advice from a tax professional or clinic if the wording remains unclear.
Calculate and protect the filing deadline
The standard period is 90 days from the date shown on the notice. The IRS describes a 150-day period for specified situations involving an address outside the United States, and official materials also recognize relevant out-of-country circumstances. The notice’s stated last day is the practical starting point, but unusual facts can affect how the statute applies.

Write the deadline on a calendar and plan to file well before it. The Tax Court states that it cannot extend a filing period set by statute. Asking the IRS for reconsideration, contacting Appeals, or waiting for a response does not by itself extend the Tax Court deadline. The IRS discusses the right to challenge its position in its Taxpayer Bill of Rights 4, while the Court’s Court Information page explains the statutory limit.
Electronic receipt has a time zone
For an electronic petition, the Tax Court generally must receive the filing by 11:59 p.m. Eastern Time on the due date. A submission made shortly before midnight in another time zone can therefore be late. Allow time to upload documents, correct validation errors, and save proof of submission.
When the deadline is close
- Use the exact date printed on the notice as your working deadline.
- Gather the notice and basic facts without waiting to assemble every piece of evidence; evidence is not attached to the initial petition.
- Submit through DAWSON or by paper using current Court instructions before the cutoff.
- Keep the electronic confirmation or reliable mailing and delivery proof.
If the date has passed or the notice has unusual service or address facts, seek qualified advice immediately. Do not rely on an assumption that a late petition can be cured.
Prepare the petition without exposing private data
Your petition identifies the case and states why you disagree with the IRS adjustment. It is not the place to prove every factual detail. The Tax Court’s current e-filing instructions and petition checklist control what must be submitted.
Information to have ready
- A clear copy of the statutory notice of deficiency.
- Your name, address, and contact information as requested in the Court’s workflow.
- The tax year or years and the amounts the notice says are due.
- A concise explanation of each adjustment you dispute and the basic reasons you believe it is wrong.
- The filing fee or the information needed for an application to waive it.
Information not to put in the petition
Do not place a Social Security number, taxpayer identification number, employer identification number, or financial-account information in the public petition. Do not attach tax returns, receipts, spreadsheets, or other evidence to the petition. DAWSON’s process separately requests identification information and the notice, with redaction directions. Follow those current directions exactly; a document that reveals sensitive information can create an avoidable privacy problem.
Keep your supporting records organized privately. The Court or the IRS may require documents later under the applicable case procedures, but the initial petition is not an evidence package.
File electronically through DAWSON
DAWSON is the Tax Court’s electronic filing system. The Court offers more than one way to create or submit a petition, so use the option that matches your preparation and the current screen labels.
- Open the Court’s petition page. Start at How to eFile a Petition and follow the link into DAWSON. Do not send a petition by ordinary email.
- Choose a petition method. DAWSON can guide you through online answers, accept the Court’s Form 2 upload, or accept a petition prepared to comply with the Court’s rules.
- Enter the case details. Use the taxpayer name, address, tax year or years, notice information, and disputed adjustments exactly as requested. Keep SSN, TIN, EIN, and financial-account data out of the petition document.
- Upload the required documents. Provide the notice copy and any taxpayer-identification statement requested by the workflow. Apply the Court’s redaction instructions before uploading.
- Pay the fee or request a waiver. Complete the fee step during filing; a case can be dismissed if the fee is neither paid nor waived.
- Submit before the cutoff. The Court generally must receive an electronic petition by 11:59 p.m. Eastern Time on the last filing date.
- Save proof. Retain the DAWSON confirmation, submission timestamp, docket information when issued, and a complete copy of what you filed.
Review every page before pressing submit. A successful upload is not a license to add evidence later through an informal email; use the Court’s filing procedures for anything submitted after the petition.

File on paper when that is the workable option
Paper filing remains available under the Tax Court’s petitioner guidance. Use the current forms and delivery instructions on Starting A Case and Guidance for Petitioners. The key issue is when the Court receives a timely, compliant petition, not when you begin drafting it.
Paper-filing safeguards
- Use the Court’s current petition form or a petition that complies with its rules.
- Include the notice copy and other items the current checklist requests.
- Remove SSNs, TINs, EINs, and financial-account numbers from the public filing and follow the Court’s separate identification instructions.
- Pay the $60 fee or submit the Court’s fee-waiver application.
- Choose a delivery method that gives you dependable evidence of delivery and leave enough time for the Court to receive the papers by the deadline.
Because the Court cannot extend the statutory filing period, mailing on the last day is risky. Check the Court’s current instructions rather than relying on an older form or address.
Pay the $60 fee or apply for a waiver
The Tax Court currently lists a $60 petition filing fee. Its fee guidance provides an application to waive that fee. Follow the Court’s current instructions for payment or waiver and confirm that the filing is complete. The Court states that a case may be dismissed when the fee is not paid or waived.
The fee is separate from the tax shown in the notice. Filing a petition does not mean you have paid the disputed deficiency; it invokes the prepayment review process. Other amounts, debts, or penalties can have separate rules.

Decide whether to elect small tax case procedure
A deficiency dispute of $50,000 or less for any one tax year, counting additions to tax and penalties, may qualify for small tax case procedure if the Tax Court accepts your election. The Court describes this procedure as simpler and generally less formal. Its decision cannot be appealed.
| Issue | Regular procedure | Small tax case procedure |
|---|---|---|
| Deficiency eligibility | No $50,000-per-year cap stated for the regular route | Disputed deficiency, additions to tax, and penalties must total $50,000 or less for the year |
| Formality | Uses the Court’s regular case procedures | Generally simpler and less formal |
| Election | No small-case election required | Taxpayer elects and the Court must agree |
| Appeal | Regular-case decisions follow the appeal rules that apply to the case | Decision cannot be appealed |
The $50,000 threshold is measured separately for each year and includes additions and penalties. Choosing the simplified route can be sensible for a modest, straightforward dispute, but the loss of appeal rights matters if the legal or factual issues are substantial. Read the Case Procedure Information before making the election; the Court, not the taxpayer alone, determines whether the case proceeds as a small tax case.
What happens after the petition is filed
Docketing and notices
After a filing is accepted, the case receives a docket number and proceeds under Tax Court procedures. Keep the docket number with every document and check Court communications for response dates, conferences, and trial-related instructions.
Settlement or litigation
Many deficiency cases settle, while others move toward a trial calendar. Filing a petition does not guarantee settlement, a particular schedule, or a result. You remain responsible for meeting Court deadlines and presenting the positions that support your case.

A timely deficiency petition generally postpones payment of the disputed tax until the case is decided, and the IRS generally may not collect that disputed amount while the case is pending. This general rule does not decide what happens to unrelated liabilities or a separate collection action, so read IRS notices carefully and seek advice when more than one tax period or debt is involved.
Represent yourself or obtain representation
You may appear without a lawyer or use a practitioner admitted to the Tax Court bar. Self-representation means you must learn and follow the Court’s filing, service, discovery, and trial requirements. The Court’s guide expressly cautions: “This guide provides information, but not legal advice, for individuals who represent themselves before the Tax Court.” Read the Guidance for Petitioners before deciding how much help you need.
When professional help is especially important
- The notice covers several years or includes large additions and penalties.
- The deadline, mailing address, or out-of-country facts make the 90- or 150-day rule uncertain.
- You need to decide whether giving up appeal rights under small tax case procedure is worthwhile.
- The case involves technical issues, business entities, third-party records, or a possible collection action in addition to the deficiency.
The Tax Court points self-represented taxpayers to clinics and pro bono resources. Start with the Court’s self-represented guidance and contact a qualified tax practitioner or Low Income Taxpayer Clinic promptly if cost is a barrier.

Filing against the wrong IRS letter
A proposed examination adjustment or collection bill is not automatically a statutory notice of deficiency. Verify the document before relying on the Tax Court route.
Waiting for the IRS to answer
Reconsideration, an Appeals conversation, or a phone call does not replace a timely petition. The statutory clock continues unless an applicable authority says otherwise.
Using the wrong time zone
DAWSON’s ordinary electronic cutoff is 11:59 p.m. Eastern Time. A local midnight assumption can produce a late filing.
Attaching evidence too early
The initial petition should not include returns, receipts, or other evidence. Follow the Court’s later instructions for documents and keep your records organized privately.
Leaving private identifiers in public documents
Remove SSNs, TINs, EINs, and financial-account numbers from the petition and apply the Court’s redaction directions to every uploaded or mailed document.
Ignoring the fee step
Pay the $60 fee or submit the waiver application as instructed. An unpaid and unwaived fee can lead to dismissal.
Choosing small-case treatment without weighing appeal rights
The $50,000-per-year limit includes additions and penalties, and a small-case decision cannot be appealed. Consider the dispute’s complexity before electing.
