13. INDIANA PRACTICE NOTES
- Specialized Indiana Tax Court. Indiana is one of the few states with a dedicated, specialized state tax court. The Indiana Tax Court has exclusive subject-matter jurisdiction over original tax appeals from final determinations of the Indiana Department of Revenue and the Indiana Board of Tax Review (IC 33-26-3-1). The Tax Court sits in Indianapolis (with statewide travel sittings) and reviews DOR matters de novo and without a jury. Practitioners must comply with the Indiana Tax Court Rules (separate from the Trial Rules) and the Court's electronic-filing requirements.
- Sixty-day protest deadline. The 60-day deadline under IC 6-8.1-5-1(b) is jurisdictional. Late protests divest the Department of authority to consider the matter. File via certified mail (or INTIME) and retain proof of timely filing.
- Letter of Findings; rehearing window. After hearing (or on the written record), the Department issues a Letter of Findings. A taxpayer dissatisfied with the Letter of Findings has 30 days under IC 6-8.1-5-1(h) to request a rehearing. Rehearing is discretionary.
- Original Tax Appeal deadline. The deadline for filing the original tax appeal in the Indiana Tax Court is set by IC 6-8.1-5-1(i) and the Tax Court Rules. Practitioners should compute and calendar the deadline conservatively from the Letter of Findings (or denial of rehearing) and verify the controlling subsection — the deadline is jurisdictional.
- Burden of proof. Under IC 6-8.1-5-1(c), the Notice is prima facie evidence that the assessed tax is owed; the burden of proving the proposed assessment is wrong is on the taxpayer, and that burden continues through the de novo Tax Court appeal.
- Payment under protest. Indiana does not generally require pre-payment to protest; however, interest under IC 6-8.1-10-1 continues to accrue during the protest. Consider paying contested amounts under protest to stop the interest meter while preserving refund-claim rights under IC 6-8.1-9-1.
- Confidentiality. Indiana tax return information is confidential under IC 6-8.1-7-1. Mark all submissions accordingly and redact SSNs where possible.
- Taxpayer Bill of Rights. The Indiana Taxpayer Bill of Rights (IC 6-8.1-1.5) and the Taxpayer Rights Advocate Office (IC 6-8.1-11-3) provide additional procedural protections, including the right to representation and the right to recordings/transcripts of hearings.

About This Template
Tax law covers the paperwork that documents income, deductions, disputes, and settlements with the IRS and state tax authorities. Protests, offers in compromise, installment agreement requests, and appeals each have their own forms, supporting documentation, and strict deadlines. Well-prepared tax correspondence is often the difference between a negotiated resolution and an enforcement action with levies, liens, or penalties.
