12. INDIANA AUDIT PRACTICE NOTES

• Specialized Indiana Tax Court. Although audit-stage advocacy is administrative, every audit response should be drafted with the Indiana Tax Court (IC 33-26) in mind. The Tax Court has exclusive jurisdiction over original tax appeals from DOR final determinations and reviews them de novo. Building the audit record carefully preserves issues for Tax Court review and avoids late-stage waiver arguments.
• Statute of limitations. The default assessment period in IC 6-8.1-5-2(a) depends on the return and tax type. A written assessment extension under subsection (i) runs to the agreed date, must include a records-preservation statement, and may be renewed by another agreement. The separate 90-day cap in IC 6-8.1-5-1(h) concerns an extension of the Tax Court appeal period, not the assessment period.
• Federal modification. For a federal modification made after December 31, 2025, IC 6-3-4-6(e) requires the Indiana amended return within one year after the modification. IC 6-8.1-5-2(j) generally extends the Department's assessment window to one year after the taxpayer files the notice; classify the tax, modification date, and any partnership rule before calendaring.
• Records preservation. IC 6-8.1-5-4 requires retention of books and records sufficient to determine liability. As a practical matter, retain all books, records, and source documents for at least the longer of (a) 3 years from the due date or filing date, (b) the period of any executed extension, or (c) the period an issue remains unresolved on protest, rehearing, or appeal.
• IDRs. Treat each IDR as a discrete formal request. Log it, track due dates, produce responsive non-privileged records on a Bates-numbered basis, and document objections in writing. Avoid informal oral responses to substantive questions; route everything through counsel.
• Penalty mitigation. Indiana's negligence penalty under IC 6-8.1-10-2.1 may be waived for reasonable cause. Document reliance on competent professionals, ambiguity of law, and good-faith compliance efforts contemporaneously with the audit response.
• Taxpayer Rights Advocate. If the audit becomes unreasonable or the auditor refuses to follow DOR procedures, the Indiana Taxpayer Rights Advocate Office (IC 6-8.1-11-3) provides an independent escalation channel.
• Confidentiality. All audit submissions are protected return information under IC 6-8.1-7-1. Mark and transmit accordingly; insist on secure file-transfer methods.
