Receiving an unfavorable decision after an IRS audit can feel discouraging. The notice may propose additional taxes and penalties, but this is not the final word. You have the right to challenge the IRS’s findings through established procedures.
Understanding the audit results notice
The IRS communicates its findings through official notices, such as a “30-day letter.” This document outlines proposed changes to your tax return and explains your rights. It serves as a proposal, not a final bill, indicating the auditor has completed their review. The agency provides this notice to give you a chance to respond before taking further action. Ignoring it can lead to more serious collection efforts.
Primary options to dispute audit findings
When you disagree with the audit’s conclusion as stated in a 30-day letter, you have several options. If you do not respond, the IRS will typically issue a Statutory Notice of Deficiency or “90-day letter,” which allows you to petition the U.S. Tax Court.
Alternatively, you can proactively challenge the findings through other administrative channels. Your options often include:
- IRS appeals: This formal process involves requesting a conference with the IRS Office of Appeals. An independent appeals officer, who was not involved in the original audit, will review your case. It provides an opportunity to present your arguments and negotiate a settlement without going to court.
- Audit reconsideration: You can request this path if you have new information to present that the auditor did not consider. You can also use it if you did not appear for the original audit or did not provide the requested information.
Both of these options have strict deadlines and documentation requirements.
Developing your post-audit strategy
Challenging an IRS decision requires a careful approach. Missing a deadline or submitting incomplete information can weaken your position and limit your future options. The rules for presenting evidence and arguing your case are specific.
An experienced legal professional can help you understand the audit report, gather the necessary documents, and build a strong case for an appeal. Properly addressing an unfavorable audit can prevent the issue from escalating into liens or levies.
