If you disagree with an IRS decision regarding an audit, a payment plan, or a levy, you generally have the **legal right to file an appeal.** The timeline for responding to an IRS letter is critical to protecting your rights. If you are uncertain of your options, seeking the advice of a qualified tax attorney is highly recommended to ensure deadlines are not missed.    ## Why File an IRS Appeal? Many taxpayers hesitate to appeal, fearing the process is rigged or unlikely to succeed. However, internal statistics often show that approximately **40% of appeals result in tax reductions.** **Key Benefits:** - **Low Initial Cost:** There are minimal administrative fees associated with filing an appeal. - **Liability Reduction:** Potential for significant reduction or elimination of the tax debt. - **Extended Timeframe:** Filing an appeal can pause certain collection actions, giving you more time to arrange financing or gather documentation. #### Supporting content - [5 Signs Your IRS Audit Results Are Worth Appealing](https://www.wolftax.com/tax-resources/5-signs-your-irs-audit-results-are-worth-appealing) - [What Happens During an IRS Appeals Conference?](https://www.wolftax.com/tax-resources/what-happens-during-an-irs-appeals-conference)    ## Disadvantages of Appealing an IRS Decision While often beneficial, there are risks to consider: - **"New Issues" Rule:** An appeals officer may identify previously unnoticed tax liabilities, potentially increasing the amount you owe. - **Asset Discovery:** During the review of an Offer in Compromise (OIC) or Installment Agreement, the officer may find additional assets or income. - **Interest Accrual:** Interest and penalties continue to accumulate during the appeal. If the appeal is unsuccessful, your total balance will be higher than when you started. #### Supporting content - [The Hidden Risks of Appealing: When It's Smarter to Walk Away](https://www.wolftax.com/tax-resources/the-hidden-risks-of-appealing-when-its-smarter-to-walk-away)    ## When to File an Appeal With the IRS Appeals are commonly filed under the following circumstances: - Disagreement with collection actions (**liens, levies, or seizures**). - Termination or modification of an **installment agreement**. - Rejection of an **Offer in Compromise**. - Disputing the findings of an **IRS audit** or the total tax amount owed. - Disagreement with **assessed penalties**. If any of these situations apply to you, filing an appeal may be a smart choice. Given the complexity of the appeals process, engaging a tax lawyer may help streamline the process. #### Supporting content - [The "90-Day Letter" Why You Can't Afford to Ignore It](https://www.wolftax.com/tax-resources/the-90-day-letter-why-you-cant-afford-to-ignore-it)    ## Types of IRS Appeals and When to Use Them ### 1. Collection Due Process (CDP) Hearings Used for disputing liens, levies, and seizures. - **Deadline:** 30 days from the date of the notice. - **Protection:** Filing a timely request **suspends levy action** while the case is pending. - **Judicial Review:** If you lose a CDP hearing, you have the right to seek review in **U.S. Tax Court.** - **Form Required:** [Form 12153](https://www.irs.gov/pub/irs-pdf/f12153.pdf) . ### 2. Collection Appeals Program (CAP) Used for installment agreement rejections or terminations. - **Speed:** CAP is generally faster than CDP. - **Finality:** Unlike CDP, the decision in a CAP appeal is **final**; you cannot take a CAP decision to Tax Court. - **Form Required:** [Form 9423](https://www.irs.gov/pub/irs-pdf/f9423.pdf) #### Supporting content - [CDP vs. CAP: Which IRS Appeal Path is Right for You?](https://www.wolftax.com/tax-resources/cdp-vs.-cap-which-irs-appeal-path-is-right-for-you)    ## How to Appeal IRS Liens and Levies Taxpayers who receive a Federal Tax Lien notice may appeal through a CDP hearing or a CAP. Similarly, tax levies can be contested through the same processes, depending on the situation.    ## How to Appeal a Rejected Offer in Compromise? If the IRS rejects an Offer in Compromise, taxpayers can appeal by submitting Form [13711](https://www.wolftax.com/tax-resources/how-to-appeal-an-irs-oic-rejection-the-form-13711-roadmap) (Request for Appeal of Offer in Compromise) within 30 days of the rejection notice.    ## How to Appeal a Trust Fund Recovery Penalty (TFRP)? Business owners assessed a TFRP can appeal by sending a written protest and a copy of Letter 1153 (Proposed Trust Fund Recovery Penalty Notification) to the address provided in the letter. The protest should outline reasons for disputing the penalty or amount assessed.    ## Taking Your Case to Tax Court If an appeal is unsuccessful, taxpayers may have the option to take their case to Tax Court, but only under specific circumstances: - **Deficiency Proceedings:** Taxpayers receiving a Notice of Deficiency ("90-day letter") can appeal additional tax assessments within 90 days. - **CDP Appeals:** After exhausting the IRS Appeals process, taxpayers may petition the Tax Court within 30 days of receiving a Notice of Determination. ### Sources: 1\) [**IRS Publication 5 (Your Rights as a Taxpayer):**](https://www.irs.gov/pub/irs-pdf/p5.pdf) This is the "Bible" for IRS appeals.
