How the IRS Appeals Process works — step by step

The IRS Appeals Process exists to give taxpayers an impartial review of IRS determinations before going to court. The Appeals Office is separate from the exam and collection functions and focuses on resolving disputes through negotiation and compromise when appropriate (IRS, Appeals Office: https://www.irs.gov/appeals).

Below is a practical, stepwise guide you can use when a notice from the IRS triggers a disagreement:

  1. Receive and read the notice carefully
  • Check the notice type and the exact deadline printed on it. Different notices carry different appeal rights and deadlines. Many audit and collection notices give you 30 days to request an appeal; some examination letters provide 60 days; a statutory Notice of Deficiency gives 90 days to file a petition in U.S. Tax Court (not an Appeals request). Always follow the date printed on your notice.
  1. Decide whether to request Appeals or pursue other remedies
  • For collection actions (e.g., levy or lien), you may be eligible for a Collection Due Process (CDP) hearing or an equivalent Collection Appeals Program (CAP) review. For audit adjustments, you generally request an Appeals conference with the Appeals Office.
  • If you receive a Notice of Deficiency (the “90-day letter”), many taxpayers file a petition in Tax Court instead of first going to Appeals.
  1. File the appropriate request on time
  • Follow the notice instructions for requesting an appeals conference or filing a written protest. A written protest is required for many cases where the amount in dispute exceeds a statutory threshold; simpler cases may accept a signed statement explaining the disagreement. The notice itself explains the required format. Missing the deadline can forfeit administrative appeal rights; however, some limited relief may exist in narrow circumstances.
  1. Assemble a clear appeals packet
  • Include a concise chronology, copies of the IRS notices, returns, schedules, receipts, bank records, and any other documentation that supports your position. If you have legal authority or IRS rulings that support your argument, include those citations.
  • In my practice I often prepare a two-page summary up front: one page with the factual timeline and one with legal arguments and requested outcomes. That helps Appeals Officers quickly understand the key issues.
  1. Attend the Appeals conference
  • Appeals conferences are usually informal and can be by phone, virtual meeting, or in person. The Appeals Officer is expected to be impartial and to review the administrative file (including the workpapers from the audit or collection case) before discussing settlement options.
  • Expect to discuss facts, legal issues, and potential settlement positions. Appeals Officers may propose concessions or alternative resolutions (e.g., penalty abatement, partial adjustments, or collection alternatives like installment agreements).
  1. If needed, submit a formal protest
  • When an informal approach doesn’t resolve the case, taxpayers can file a formal written protest. The Appeals Office will use this protest as the basis for a more detailed administrative review.
  1. Receive Appeals determination
  • The Appeals Office issues a decision that can sustain, modify, or fully reverse the IRS action. If Appeals sustains the IRS position and you still disagree, your next step may be to litigate in U.S. Tax Court, the U.S. District Court, or the Court of Federal Claims, depending on the case and your procedural posture.
  1. Post-decision options
  • If Appeals rules for the IRS, you may have court options (for example, filing a petition in Tax Court if you received a Notice of Deficiency or seeking refund litigation in district court after paying the tax). If Appeals rules for you, the IRS will adjust the account accordingly.

Typical timelines and realistic expectations

  • Deadlines to request Appeals: Most commonly 30 days from the date of the notice, but check the notice for exact timing. Some notices allow 60 days; a Notice of Deficiency gives 90 days for Tax Court (IRS Publication 1 and Appeals pages clarify rights and deadlines).
  • Appeals conference scheduling: Appeals will generally schedule a conference within a few weeks to a few months depending on caseload and complexity.
  • Time to final determination: Simple cases can resolve in a few months. More complex matters often take 6–12 months; extremely complex or heavily researched legal issues may take longer.

The IRS publishes general guidance but does not guarantee set timelines; plan for several months and keep track of statute of limitations on assessments and collections for your particular tax year.

Preparation checklist (practical)

  • Read the IRS notice and circle the deadline.
  • Make a one-page summary of facts and positions.
  • Gather primary documents (returns, receipts, contracts, bank statements).
  • Locate any legal authority or IRS guidance that supports your position.
  • Decide if you need representation: a CPA, EA, or tax attorney can handle technical legal arguments and negotiation.
  • Keep a record of all calls, dates, names, and conference notes.

How appeals differ from audits and why that matters

Appeals is not a second audit. Its role is to provide an independent review and to resolve disputes administratively. Unlike exam teams, Appeals Officers evaluate the entire case file and consider hazards of litigation—meaning they assess the strengths and weaknesses of both the taxpayer’s and the IRS’s positions and may settle for less than full IRS asserted amounts to avoid litigation risk. For a deeper comparison, see How Appeals Differ from Audits: Strategy and Outcomes.

Common mistakes taxpayers make

  • Waiting to act: Missing the appeal deadline is a frequent and often avoidable error.
  • Overwhelming Appeals with poor organization: A clear, tightly argued packet is more persuasive than voluminous but disorganized files.
  • Treating Appeals like court: Appeals is administrative and collaborative. Focus on clear facts and settlement levers, not courtroom theatrics.
  • Failing to discuss collection alternatives: If collections are the issue, propose realistic payment arrangements, offers in compromise (where eligible), or provide hardship documentation early.

Real-world examples (anonymized)

  • Audit adjustment reversed: I represented a client after an audit adjustment increased reported income due to a coding error. A concise, source-document-based appeals packet and a short conference led Appeals to reverse the adjustment without litigation.
  • Penalty abatement success: Another client received an accuracy-related penalty. By documenting reasonable cause (medical emergency and timely reliance on a paid preparer), Appeals abated the penalty.

Frequently asked questions (brief answers)

  • How long do I have to appeal? Check your notice—commonly 30 days, sometimes 60; a Notice of Deficiency requires a Tax Court petition within 90 days.
  • Can I represent myself? Yes. Many taxpayers represent themselves, but professional representation can improve results on complex legal or valuation issues.
  • Will Appeals stop collection actions? If you timely request a CDP hearing, certain collection activities (like levy) are put on hold until the hearing completes (see IRS collection due process guidance).

Final professional tips

  • Treat deadlines with the same urgency as a court filing.
  • Be concise: an organized packet with a clear request is most effective.
  • Use settlement levers: penalty abatement, reasonable cause, and compromise options can yield better outcomes than insisting on a full reversal.
