South Dakota tax penalties at a glance
South Dakota is one of the states with no broad personal income tax, so there is no state income-tax penalty for individuals. The South Dakota Department of Revenue 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.
Source: South Dakota 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 South Dakota penalty waived
South Dakota has no income tax; penalties/interest apply to sales/use and excise taxes. Request a waiver via Form 1810; good-faith compliance is considered.
Most people who owe a South Dakota 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 South Dakota 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 South Dakota, federal abatement requests are processed through the IRS service center in Ogden, UT.
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 South Dakota 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 South Dakota 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 Ogden, UT service center, and build the reasonable-cause substantiation. The work is contingency-based: if we do not recover, you do not pay.
