New Hampshire tax penalties at a glance
New Hampshire is one of the states with no broad personal income tax, so there is no state income-tax penalty for individuals. The New Hampshire Department of Revenue Administration still assesses penalties and interest on other taxes — sales and use, franchise, or excise — and those figures are below. Your federal IRS penalties apply no matter which state you are in.

Getting a New Hampshire penalty waived
Penalties are waived when the failure was due to reasonable cause and not willful neglect. New Hampshire repealed its Interest & Dividends Tax effective for periods after Dec 31, 2024, so there is no broad individual income tax.
Most people who owe a New Hampshire 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 New Hampshire 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 New Hampshire, federal abatement requests are processed through the IRS service center in Andover, MA.
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 New Hampshire 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 New Hampshire 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 Andover, MA service center, and build the reasonable-cause substantiation. The work is contingency-based: if we do not recover, you do not pay.
