Understanding the Indiana Notice of Tax Assessment
What This Document Represents
The Indiana Notice of Proposed Assessment is an official letter from the Indiana Department of Revenue informing you that the state has reviewed your tax account and determined you owe additional taxes, penalties, interest, or a combination of these amounts. This notice marks the first stage of Indiana’s three-stage tax collection process, and your response to it affects your account status, future enforcement actions, and payment obligations.
Why Ignoring This Notice Has Consequences
Ignoring this notice will not make it go away. Indiana law requires the Department of Revenue to advance the collection process if you do not respond by the due date, and you waive your right to protest if you do not respond at the proposed assessment stage.
Why the State Issues This Notice
The Indiana Department of Revenue sends a Notice of Proposed Assessment for several common reasons. A tax return you filed showed an error after state review, you did not file a return when required, or the state matched information from your employer or financial institutions to your account and found a discrepancy.
Outstanding balances from prior years may require formal documentation by the state. Routine audits or reviews of accounts lead to assessments based on those findings as part of the standard administrative process for documenting tax liabilities before pursuing collection.
What Happens If You Do Not Respond
The Indiana Department of Revenue will continue collection efforts if you do not respond to or address the Proposed Assessment Notice. Indiana law requires the Department of Revenue to advance to the next collection stage, which may include sending a demand notice with a 20-day deadline, placing your account in collection status, offsetting future tax refunds, or pursuing wage garnishment or bank levies.
Legal Principles You Should Understand
Under Indiana Code IC 6-8.1-5-1(c), the notice of proposed assessment is prima facie evidence that the Department of Revenue’s claim for unpaid tax is valid. The burden of proving that the proposed assessment notice is wrong rests with you, and the Department of Revenue presumes its assessment is correct under Indiana law.
Your Right to Protest and Critical Deadlines
You have exactly 60 days from the date printed on the proposed assessment to file a written protest. The 60-day deadline to file a written protest with the Department of Revenue is required by statute and cannot be extended. Missing this deadline means you waive your right to protest at the administrative level. Your only recourse after the 60 days is to pay the assessment or file in the Indiana Tax Court.
Steps to Take After Receiving This Notice
Read the entire assessment letter carefully and locate the notice date, assessment date, and any deadlines mentioned. Verify that your name, address, Social Security number or business identification number, and other identifying information on the notice are correct. Identify which tax year or years the assessment covers and note whether this concerns income tax, sales tax, unemployment insurance tax, or another type of state tax. Find the dollar amount the state says you owe and look for a breakdown showing how much is original tax, how much is interest, and how much is penalties, which the Proposed Assessment Notice typically includes in an audit summary report.
Gathering Your Records
Gather your tax records for the year in question and locate your original tax return for the year shown in the notice. Collect receipts, W-2 forms, 1099 forms, bank statements, or other documents you used to prepare that return during the audit process. Organizing these materials before contacting the Department of Revenue helps you present a complete picture of your tax situation and supports any claims you make in your written protest.
Comparing the Assessment to Your Records
Compare what the notice says you owe to your own records. Review whether the notice says you did not report income and check whether that income appears on your return, look for obvious errors such as wrong numbers or math mistakes, and write down anything that does not match your records.
How to File a Protest
Your protest must be filed in writing and must be accompanied by the Protest Submission Form, which is State Form 56317. You may file your Protest Submission Form by mail to the Indiana Department of Revenue, Legal Division, MS 102, 100 N. Senate Avenue, Room N248, Indianapolis, IN 46204, or electronically via the Indiana Taxpayer Information Management Engine.
What to Include in Your Protest
Provide as much relevant information as possible when filing your Indiana tax assessment appeal using the Protest Submission Form. Include the tax period at issue, the tax type at issue, the specific part of the proposed assessment you believe is incorrect, and the particular reasons why you disagree. Attach copies of all supporting documentation you think supports your protest and explain the specific result you desire, such as the exact dollar amount you believe is correct, if you disagree with the assessment amount shown on the Proposed Assessment Notice.
Payment Options and Collection Stages
If you owe the amount stated and can pay, contact the Department of Revenue to arrange payment. Ask about payment options, including full payment, payment plans, and where to send payment. Keep all receipts and proof of payment, showing the date and amount paid. Filing a Protest Submission Form does not eliminate your obligation to explore payment arrangements if you cannot pay the full amount within the 60 days.
Understanding the Demand for the Payment Stage
After a proposed assessment becomes final due to non-response or denial of protest, the Department of Revenue issues a demand notice, allowing exactly 20 days to respond. The demand notice stage has a specific three-installment option: pay one-third within 20 days to receive a new demand notice, pay one-half of that second notice within 20 days to receive another notice, and pay the balance in full within the final 20 days.
What Happens at the Tax Warrant Stage
If unpaid, the liability becomes a collectable judgment, and the Department of Revenue may proceed to a tax warrant stage. The state may add additional penalties and interest charges over time, and failing to respond eliminates any opportunity to address the issue before it escalates.
Common Errors to Avoid
Ignoring the notice entirely will not resolve the issue, as not responding to an Indiana Notice of Proposed Assessment does not make it disappear. Missing the 60-day deadline to file your Protest Submission Form or request a hearing eliminates your administrative appeal rights. Sending original documents to the state instead of copies puts your records at risk. Failing to keep a copy of everything you send or receive prevents you from proving what was communicated or when without your own records.
