1. Preparing an IRS Audit Response after Receiving the Notice
An IRS audit notice identifies the examination and generally provides information about the return, tax period, or issues the agency intends to review. Taxpayers should evaluate the scope of the audit notice before gathering financial records or submitting information to the revenue agent. The scope of an IRS Audit Defense review may include the examination notice, requested records, and authorized communications with the revenue agent.
Reviewing the Notice and Organizing Relevant Records
Initial preparation involves reviewing filed tax returns, supporting schedules, and accounting workpapers relevant to the audit years. Legal representatives assist in identifying potentially privileged communications, such as legal advice regarding tax positions, while organizing standard financial documentation. An organized record can help counsel identify factual disputes and track the documents provided during the examination.
2. Responding to Information Document Requests
During an examination, a revenue agent may use Information Document Requests (IDRs) to request accounting records, bank statements, contracts, or other relevant materials. An IDR generally identifies the requested records and a response date, and additional time may be discussed when assembling complex materials. Legal representatives review the scope of each IDR, identify responsive records, and evaluate potentially privileged material before production.
IDR Scope, Response Timing, and Representation
IDR review involves identifying responsive records, evaluating the scope of the request, and considering whether particular communications or materials are privileged. Routing written submissions and revenue agent inquiries through an authorized representative helps maintain an accurate procedural record. When an interview is requested, counsel can prepare for the factual issues expected to arise and participate within the scope of the representation.

3. Reviewing Proposed Adjustments and Requesting Appeals
Upon concluding the audit examination, the revenue agent prepares an examination report outlining proposed adjustments to tax liabilities and applicable penalties. When proposed adjustments remain disputed, the IRS may issue a 30-day letter with an examination report and an agreement form explaining the available response options. Legal counsel reviews the factual and legal basis for proposed deficiencies and penalty assertions.
Examination Reports and the 30-Day Letter Options
A taxpayer who agrees with proposed adjustments may sign the applicable agreement form, which can permit assessment without further administrative dispute over the agreed items. Alternatively, taxpayers who dispute the findings can submit a formal written protest within 30 days to request administrative review. A timely protest asks the IRS to reconsider the disputed adjustments and, if they remain unresolved, forward the matter to the Independent Office of Appeals.
4. Presenting the Dispute to IRS Independent Appeals
The IRS Independent Office of Appeals operates separately from the IRS office that made the original determination and reviews eligible tax disputes without trial. Appeals Officers evaluate disputed adjustments by considering the factual record, statutory interpretations, and relevant legal precedents. Representative submissions present written legal arguments and supporting documentation to address the revenue agent's findings.
Hazards of Litigation and Administrative Resolution
Appeals Officers assess dispute settlement possibilities based on a hazards-of-litigation analysis, evaluating potential trial outcomes for both the taxpayer and the government. Appeals may resolve disputed issues through an agreement reflecting the matters settled by the parties. For taxpayers who have already paid disputed amounts, administrative review may also intersect with Corporate Tax Refund and Recovery procedures.
5. Choosing a Federal Tax Litigation Forum
Taxpayers who receive a Statutory Notice of Deficiency must select an appropriate federal judicial forum if they choose to pursue litigation. Selecting the United States Tax Court allows taxpayers to contest proposed deficiencies without paying the disputed balance upfront. Legal counsel evaluates procedural differences between prepayment litigation in Tax Court and refund litigation in Federal District Court or the United States Court of Federal Claims.
Tax Court Petitions and Refund Litigation Procedures
Filing a petition in the United States Tax Court requires strict compliance with statutory deadlines, generally within 90 days from the date the Notice of Deficiency is mailed, or 150 days if the notice is addressed to a person outside the United States. Alternatively, taxpayers may pay the full deficiency, file an administrative refund claim with the IRS, and initiate refund litigation in Federal District Court or the United States Court of Federal Claims. After a trial-level decision, any further review follows separate Federal Appeals procedures and filing rules.
6. Frequently Asked Questions
Can an attorney communicate with the IRS revenue agent on my behalf?
An authorized attorney with a properly executed Power of Attorney (Form 2848) can handle communications, written responses, and meetings with the IRS revenue agent. Taxpayer participation may still be required for specific interviews or factual clarifications.
Does receiving a 30-day letter mean I must go directly to Tax Court?
Receiving a 30-day letter provides an opportunity to file a formal written protest and request administrative review with the IRS Independent Office of Appeals. In a deficiency case, the Tax Court filing period generally begins with a Statutory Notice of Deficiency, not a 30-day letter.
