Indiana tax penalties at a glance
When you file or pay Indiana taxes late, the Indiana Department of Revenue adds a penalty and charges interest on the unpaid balance. These state penalties are assessed under Indiana law and are entirely separate from any federal IRS penalty on your federal return.
Source: Indiana Department of Revenue (official guidance). Penalty caps and interest rates change — several states reset interest quarterly — so verify the current figure before relying on it.
Getting a Indiana penalty waived
Request abatement via the INTIME portal or Form 53054, under the reasonable-cause standard (IC 6-8.1-10-2.1).
Most people who owe a Indiana penalty also owe a federal IRS penalty — and the federal one is usually larger. The good news: federal penalties can often be removed entirely through first-time abatement or reasonable cause. That is the part our practice handles.
The federal side: IRS penalties & Form 843
The IRS does not assess penalties differently in Indiana than anywhere else — failure-to-file, failure-to-pay, and failure-to-deposit penalties are governed by federal law and apply uniformly nationwide. What changes by state is the IRS service center your case routes through. For Indiana, federal abatement requests are processed through the IRS service center in Kansas City, MO.
The mechanism is the same everywhere: Form 843, mailed with substantiation. The legal grounds are first-time penalty abatement, reasonable cause, statutory exception, or administrative waiver. When abatement is granted, the IRS refunds the penalty and the interest it charged on that penalty.
What our practice does for Indiana taxpayers
We represent clients in all 50 states under IRS Circular 230 authorization. Because federal abatement is state-agnostic, location is rarely a constraint. For Indiana clients specifically, we pull your IRS transcripts (via Form 8821), confirm exactly which penalties were assessed and for which periods, route Form 843 to the Kansas City, MO service center, and build the reasonable-cause substantiation. The work is contingency-based: if we do not recover, you do not pay.
