EA Part 3 IRS Appeals and Tax Court: Taxpayer Options After an Audit

The Pathway from Audit to Resolution

When an IRS examination results in proposed changes a taxpayer disagrees with, the dispute does not have to end in Tax Court. The IRS has built several dispute resolution mechanisms into the process — and the EA exam tests each one. Understanding the sequence of notices, the deadlines, and the forum choices is essential for Part 3.

The 30-Day Letter

After an examination, if the taxpayer and the Revenue Agent do not reach agreement, the IRS issues a 30-day letter (also called a preliminary notice or Revenue Agent's Report). This letter:

• Explains the proposed adjustments
• Gives the taxpayer 30 days to request an Appeals conference
• Does not trigger Tax Court rights on its own

If the taxpayer ignores the 30-day letter or cannot reach agreement at Appeals, the IRS proceeds to a formal notice.

The Statutory Notice of Deficiency (90-Day Letter)

The statutory notice of deficiency — colloquially called the 90-day letter — is one of the most tested concepts in Part 3. Key facts:

• It gives the taxpayer 90 days (150 days if the taxpayer is outside the United States) to file a petition with the U.S. Tax Court.
• The IRS cannot assess the deficiency during this 90-day window without the taxpayer's consent.
• If the taxpayer does not petition Tax Court within the 90-day window, the IRS assesses the tax and the only remaining remedy is to pay and sue for refund in U.S. District Court or the Court of Federal Claims.
• Filing a Tax Court petition does not require paying the disputed tax first.

IRS Office of Appeals

The IRS Office of Appeals is an independent function within the IRS, separate from the Examination and Collection divisions. Its mission is to resolve tax disputes without litigation on a basis that is fair to both the government and the taxpayer.

A taxpayer may request an Appeals conference:

• After receiving a 30-day letter (pre-assessment)
• During collection activity (Collection Due Process)
• After certain IRS actions such as lien filings, levy notices, or rejection of installment agreement requests

Appeals Officers weigh the hazards of litigation — meaning they consider what outcome a court would likely reach — when evaluating settlement positions. This pragmatic approach means Appeals can settle cases on partial concessions that neither the taxpayer nor the IRS field function could achieve on their own.

Fast Track Settlement

Fast Track Settlement (FTS) allows a taxpayer and IRS Examination to work with an Appeals mediator before a 30-day letter is even issued. It is available for small business and self-employed taxpayers and can resolve issues in as little as 60 days. FTS is not the same as a standard Appeals conference and does not require the case to leave the Examination function.

Tax Court

Regular Tax Court

The U.S. Tax Court is the primary venue for contesting a tax deficiency without prepaying the disputed amount. To petition Tax Court, the taxpayer must have received a statutory notice of deficiency and file the petition within the 90-day window. Tax Court judges are specialists in federal tax law.

Cases are decided by one of the 19 Tax Court judges, and opinions can be reviewed by the U.S. Court of Appeals. Regular Tax Court cases involve amounts over $50,000 per year.

Small Tax Case Procedure (S Cases)

For disputes of $50,000 or less per tax year, taxpayers may elect the Small Tax Case (S Case) procedure. Benefits include:

• Simplified, informal procedures
• Lower filing fees
• Faster resolution

The significant limitation: S Case decisions cannot be appealed. The decision is final and binding. Taxpayers should understand this trade-off before electing the small case procedure.

U.S. District Court and the Court of Federal Claims

Both the U.S. District Court and the Court of Federal Claims require the taxpayer to pay the disputed tax in full first, then file a refund claim, have the claim denied (or wait six months), and then file suit. These venues are called "pay-first" courts.

Key differences:

• U.S. District Court: The only tax forum where the taxpayer can request a jury trial. Cases are heard by federal district judges who may lack specialized tax expertise.
• Court of Federal Claims: Located in Washington, D.C.; no jury trial available. Judges have significant federal tax experience.

Taxpayers typically choose District Court when they believe a jury would be sympathetic, or when the legal issue involves Constitutional claims better suited to that forum.

Collection Due Process Appeals

Collection Due Process (CDP) is a separate appeal right triggered by collection activity rather than audit adjustments. A taxpayer who receives a Notice of Federal Tax Lien filing or a Final Notice of Intent to Levy may request a CDP hearing within 30 days of the notice. At the CDP hearing, the taxpayer may:

• Dispute the underlying liability (if they had no prior opportunity to contest it)
• Propose collection alternatives (OIC, installment agreement, CNC status)
• Raise due process violations

After the CDP hearing, the taxpayer has 30 days to petition Tax Court for review of the Appeals determination. A taxpayer who misses the 30-day CDP deadline may request an equivalent hearing, but they lose the right to Tax Court review.
