Indiana Form PEN-1 Penalty Abatement Request: Reasonable Cause and Denials

Indiana Form PEN-1, the Penalty Abatement Request (State Form 53054), is how you ask the Indiana Department of Revenue (DOR) to waive the 10 percent penalty added when you file or pay a state tax late. A successful request erases the penalty only. You still owe the underlying tax and interest, which accrues at 7 percent annually for 2026. You can submit the form through DOR’s INTIME portal or by mail, and you need a separate form for each tax account and each period.

What Reasonable Cause Actually Means

DOR waives the penalty only if you can show your late filing or payment resulted from reasonable cause and not willful neglect.1Indiana General Assembly. Indiana Code 6-8.1-10-2.1 – Liability for Penalty; Reasonable Cause Presumption The legal test is whether you exercised ordinary business care in trying to meet your tax obligations.2Legal Information Institute. 45 IAC 15-11-2 – Liability for Penalty In practical terms, you have to tie the missed deadline to something specific that was outside your control.

The circumstances that tend to support a waiver include:

  • Serious illness or incapacitation that physically prevented you from filing or paying during the relevant period.
  • Death of the taxpayer or the tax preparer, occurring close enough to the deadline that no one else could step in.
  • Destruction of the records you needed to file, such as a fire or flood.
  • Reliance on written DOR guidance, instructions, or rulings that turned out to be incorrect or misleading.2Legal Information Institute. 45 IAC 15-11-2 – Liability for Penalty

DOR also weighs the nature of the tax, relevant court decisions, and your prior compliance history when deciding whether your explanation is credible.2Legal Information Institute. 45 IAC 15-11-2 – Liability for Penalty A clean filing record helps because it supports the argument that the lapse was isolated rather than habitual.

Reasons That Usually Fail

Willful neglect, meaning a conscious choice to skip filing or paying, disqualifies you regardless of the amount at stake.1Indiana General Assembly. Indiana Code 6-8.1-10-2.1 – Liability for Penalty; Reasonable Cause Presumption Several other explanations almost never succeed on their own:

  • Not having the money to pay. Lack of funds by itself is not reasonable cause; you would need additional circumstances showing you tried to comply despite the hardship.
  • Relying on a tax preparer. You remain responsible for your own tax obligations, and blaming the preparer for a missed deadline rarely works.
  • Not knowing the filing requirement or due date.
  • Simple mistakes, forgetfulness, or misreading a notice.

Most rejected requests fall apart here. The explanation section of PEN-1 is not the place to vent about the penalty or describe general financial stress. It needs a specific event, tied to specific dates, that directly caused the late filing or payment.

Filling Out the Form

Download the current version of Form PEN-1 (State Form 53054) from the DOR website or forms.in.gov.3Indiana Department of Revenue. Indiana Form PEN-1 – Penalty Abatement Request If you owe penalties for two tax years or two different tax types, that means two forms.

Enter your full legal name, mailing address, and the correct taxpayer identification number: Social Security Number for individuals, FEIN for businesses. Getting this wrong can disconnect the request from your tax account and delay the review.3Indiana Department of Revenue. Indiana Form PEN-1 – Penalty Abatement Request

Check the box for the tax type the penalty relates to (individual income, fiduciary, corporate, business taxes such as sales or withholding, fuel, or excise). Then enter the account number and tax period exactly as they appear on your billing notice or proposed assessment. Those fields determine which DOR division reviews your case and, if you mail the form, which PO Box it needs to go to.3Indiana Department of Revenue. Indiana Form PEN-1 – Penalty Abatement Request

The Written Explanation

The narrative section carries the most weight. Write a factual account that ties the hardship directly to the tax period in question. Dates matter. If you were hospitalized from March 10 through April 25 and the return was due April 15, say so. Vague statements like “I had health issues” invite denial.

Your explanation is made under penalty of perjury, so every assertion must be truthful and verifiable.1Indiana General Assembly. Indiana Code 6-8.1-10-2.1 – Liability for Penalty; Reasonable Cause Presumption Attach documentation for anything you reference: medical records, discharge summaries, fire or police reports, death certificates, or copies of the DOR correspondence you relied on. The form instructions state that missing documentation can lead to denial on its own.3Indiana Department of Revenue. Indiana Form PEN-1 – Penalty Abatement Request

If someone else is filing on your behalf, such as an accountant or attorney, attach a completed Power of Attorney (POA-1) authorizing DOR to discuss the specific tax type with them. A POA-1 is not needed if the representative is already listed on the return for the period in question, and an electronic POA can be completed in INTIME.3Indiana Department of Revenue.

Before signing, confirm every blank is filled and that all dollar amounts match your most recent billing notice.

Submitting the Form

The fastest route is DOR’s INTIME portal at intime.dor.in.gov. Log in, go to “All Actions,” select “Legal protests and abatements,” and choose “Submit penalty abatement request.”4Indiana Department of Revenue. Request a Penalty Abatement You can upload documents and get a confirmation number for your records.

If you mail the form, send it with all supporting documents to the address that matches the tax type you checked:3Indiana Department of Revenue. Indiana Form PEN-1 – Penalty Abatement Request

  • Individual or Fiduciary: Indiana Department of Revenue, PO Box 7207, Indianapolis, IN 46207-7207
  • Corporate: Indiana Department of Revenue, PO Box 7206, Indianapolis, IN 46207-7206
  • Business Taxes (sales, withholding, etc.): Indiana Department of Revenue, PO Box 6197, Indianapolis, IN 46206-6197
  • Fuel-Related: Indiana Department of Revenue, PO Box 6080, Indianapolis, IN 46206-6080
  • Excise Tax: Indiana Department of Revenue, PO Box 901, Indianapolis, IN 46206-0901

Sending the form to the wrong PO Box routes it to the wrong division and slows everything down.

What Happens After You File

DOR reviews your request against the reasonable-cause standard and the evidence you attached. No official source specifies a guaranteed timeline; responses generally take several weeks to a few months depending on caseload and complexity. You will receive a written notice with one of three outcomes: a full grant that removes the entire penalty, a partial grant covering some periods but not others, or a denial.

Interest continues to accrue on any unpaid tax balance during the review. If you can pay the underlying tax while the abatement is pending, doing so stops interest from growing even before the penalty question is decided.

If DOR Denies Your Request

A denial can be protested. You have 60 days from the date DOR issues the assessment or denial to file a written protest, and that deadline is statutory and cannot be extended.5Indiana Department of Revenue. Appeals Your protest should explain why you disagree, include any new evidence, and request a hearing if you want one. DOR will schedule the hearing and notify you of the date by mail.

If DOR issues a final determination against you, you have 90 days to appeal to the Indiana Tax Court, or 90 days from the denial of a rehearing if you requested one. DOR will grant an additional 90 days on request.5Indiana Department of Revenue. Appeals Tax Court is more formal and typically involves legal representation, so consulting a tax attorney before filing at that level is worth considering.
