Tax penalties in South Dakota can accumulate quickly due to missed deadlines, underpayments, or unforeseen financial hardships. However, the South Dakota Department of Revenue provides a formal process known as penalty abatement, which allows qualifying taxpayers to reduce or eliminate specific state-imposed penalties. This guide outlines the eligibility criteria, application procedures, and supporting documentation required to request relief effectively.

Understanding the state's penalty relief options is essential to restoring financial control for working-class and middle-income taxpayers burdened by unpaid taxes or late filing fees. South Dakota permits abatement when taxpayers can demonstrate reasonable cause, departmental error, or a broader misunderstanding of the law. Relief is not automatic; applicants must present a clear explanation supported by relevant records to justify their request.

It’s also essential to distinguish South Dakota’s penalty abatement process from federal IRS programs. Although some terms and procedures may seem similar, the South Dakota Department of Revenue operates separately, with its own criteria, timelines, and application standards. By understanding how state-specific penalty rules apply, taxpayers can make informed decisions, navigate the relief process confidently, and work toward resolving their obligations with greater clarity.

What Is South Dakota Penalty Abatement?

Penalty abatement is a formal process that lets the South Dakota Department of Revenue lower or eliminate penalties and interest added to a taxpayer's account. This relief is usually given when the taxpayer can show that they acted in good faith, tried to pay their taxes, or had to deal with things out of their control, like a natural disaster or a serious illness.

How Penalty Abatement Differs from IRS Penalties

South Dakota's approach to lowering penalties is different from the IRS's. The IRS has a "First Time Abate" program, but South Dakota requires a written request that follows state law. Understanding the state's operations is crucial for those familiar with federal relief systems.

Penalties vs. Interest vs. Tax

Understanding the difference between the tax, penalties, and interest is key:

  • Tax: The base amount you owe for a given tax year based on your income, business activity, or applicable tax type.
  • Penalties: Additional charges assessed for violations such as late filing, failure to pay, or filing incorrect information returns.
  • Interest: Ongoing charges that accrue on unpaid balances—typically at an effective interest rate set by statute.

Penalty abatement does not eliminate the total tax due but may reduce extra financial burdens caused by late payment or underpayment.

Types of Tax Penalties in South Dakota

South Dakota imposes various tax penalties for noncompliance with state tax laws. These penalties are assessed when taxpayers fail to file, pay, or comply with state requirements by the appropriate due date.

Understanding Late Filing, Late Payment, and Failure to File Penalties

Taxpayers may face a late filing penalty if they submit their tax return after the deadline. A late payment penalty may apply if the return is filed, but the balance due remains unpaid. A failure to file a penalty—often more severe—can also be assessed. These penalties are in addition to the failure-to-pay penalty.

How Estimated Tax Penalties Are Assessed

South Dakota taxpayers who don’t make adequate estimated tax payments throughout the year may incur tax penalties, even if they file their returns on time. These penalties are generally based on how much income tax was underpaid during the year and when payments were missed.

Common Penalties Breakdown

Late Filing Penalty

  • Cause: Filing a tax return late
  • Amount: 10% of tax due (minimum $10)
  • Relief Eligibility: Reasonable cause, department delay

Late Payment Penalty

  • Cause: Not paying the total tax by the original due date
  • Amount: Included in 10% penalty
  • Relief Eligibility: Reasonable cause, department delay

Interest Charges

  • Cause: Ongoing unpaid tax balance
  • Amount: 1% per month (minimum $5 first month)
  • Relief Eligibility: May be abated due to department negligence

False Return Penalty

  • Cause: Filing a fraudulent tax return
  • Amount: 50% of tax due
  • Relief Eligibility: Limited relief; must show lack of fraudulent intent

These penalties may be combined, especially when a taxpayer misses the filing deadline and fails to pay enough taxes by the April tax deadline or the extended due date. Interest charges may also continue accruing until the balance is resolved.

Understanding which penalties apply to your account will help you determine whether to request penalty abatement, file a formal request, or seek assistance with a payment plan or installment agreement.

Legal Grounds for Relief

To qualify for penalty abatement in South Dakota, you must demonstrate that your situation meets one or more of the legal criteria outlined by state law. The South Dakota Department of Revenue evaluates each request on a case-by-case basis, considering whether the facts support reasonable cause, departmental delay, or other approved conditions. Below are the primary legal justifications you can use when requesting relief.

1. Reasonable Cause

The most common basis for relief is reasonable cause. This legal standard applies when a taxpayer genuinely attempts to meet their tax obligations but cannot do so due to circumstances outside their control.

Examples of reasonable cause include:

  • A natural disaster that destroyed records or prevented timely filing
  • Serious illness, death, or incapacity affecting the taxpayer or an immediate family member
  • Destruction of business records due to fire, flood, or other casualty
  • Inability to obtain critical information returns needed to file on time
  • Other unexpected situations that made it impossible to pay taxes or file accurately

To support your claim, provide dated documentation that ties the event directly to the tax filing deadline or payment due date.

2. Department Delay or Error (SDCL 10-59-28)

Under SDCL 10-59-28, the Department of Revenue may reduce or eliminate penalties and interest if negligent in issuing a timely notice. If the department took too long to notify you of your tax liability or penalty, and that delay contributed to further noncompliance, you may qualify for relief.

Example:

You paid estimated tax payments on time, but the Department failed to apply them correctly and sent notice months later. This delay could justify relief if it caused unnecessary interest or failure to pay penalty charges.

3. Widespread Misunderstanding (SDCL 10-59-31)

South Dakota law allows for relief when many taxpayers misunderstood the application of a tax law. Under SDCL 10-59-31, you may be eligible for abatement if:

  • The public widely misinterprets the transaction involved
  • You made a good-faith attempt to determine taxability
  • You have documentation (e.g., industry guidance or prior rulings) supporting the misunderstanding

This ground is beneficial in cases involving new tax policies or technical interpretations of income tax law.

4. Reliance on Written Advice (SDCL 10-59-27)

According to SDCL 10-59-27, you are entitled to rely on written advice provided by the Department of Revenue—even if that advice is incorrect. If a department representative provided guidance in writing and acted based on that information, you may request abatement of penalties and interest.

Include a copy of the written communication and show that you followed the instructions in good faith.

Knowing these legal grounds strengthens your request and shows that your situation fits with known exceptions. Getting penalty relief approved in South Dakota is all about using the right reasons and having strong evidence.

How to Request Penalty Abatement (Step-by-Step)

If you think you qualify for penalty abatement in South Dakota, following the steps to increase your chances of getting it is essential. The South Dakota Department of Revenue doesn't have a standard abatement form, but they want a well-organized, clearly written request with the proper paperwork.

Follow these seven steps to submit a strong penalty relief request:

Step 1: Review Your Penalty Notice

Start by reading the IRS or the South Dakota Department of Revenue notice you received. You’ll need to identify:

  • The type of penalty assessed (e.g., late filing penalty, underpayment penalty)
  • The tax year and due date involved
  • The amount of the penalty and interest
  • The reason for the penalty
  • The deadline for responding or appealing

This notice is your reference point when drafting your request.

Step 2: Identify Grounds for Relief

Determine which legal justification applies to your situation:

  • Reasonable cause (e.g., natural disaster, illness, inability to access your bank account)
  • Departmental delay or error
  • Widespread misunderstanding
  • Reliance on written advice

Please ensure that your case's facts align with the standards outlined in South Dakota Codified Law, such as SDCL 10-59-28 or 10-59-31.

Step 3: Gather Supporting Documentation

You’ll need to provide evidence that supports your request. This may include:

  • Proof of hospitalization, illness, or death in the family
  • Records of natural disasters, such as insurance claims or FEMA notices
  • Financial hardship statements, bank records, or payment records
  • Copies of written advice from the Department of Revenue
  • Any previous estimated tax payments or installment payments made
  • Screenshots or mail confirming filing deadline confusion or due date issues

Make sure dates and details match your explanation.

Step 4: Draft a Complete Request Letter

Write a formal letter addressed to the South Dakota Department of Revenue. Your letter should include:

  • Your name, address, and taxpayer ID number
  • The tax period(s) and penalty type(s) involved
  • A clear subject line (e.g., Request for Penalty Abatement – Tax Year 2024)
  • A concise explanation of what happened and why you’re requesting relief
  • Citations to relevant statutes (e.g., SDCL 10-59-28) or Department rules
  • A list of supporting documents included
  • Your contact information and signature

Step 5: Submit the Request

You can submit your abatement request by mailing it to:

South Dakota Department of Revenue
445 East Capitol Avenue
Pierre, SD 57501

Alternatively, call (605) 773-3311 to inquire about electronic submission options or email delivery instructions.

Step 6: Follow Up

After 2–3 weeks, follow up by:

  • Call the Department to confirm your request was received
  • Asking for a case or reference number (if applicable)
  • Keeping a log of all follow-up conversations, including names and dates

Keep copies of everything—letters, receipts, and call logs.

Step 7: Understand Your Right to Appeal

If your request is denied, you still have the right to appeal. According to SDCL 10-59-9 and 10-59-26, you may:

  • Request a hearing before an impartial examiner
  • Appeal to the circuit court or the South Dakota Supreme Court

Note: Appealing may require legal guidance. For hefty penalties or complex issues, consider working with a tax professional.

Common Mistakes to Avoid

Even if you qualify for penalty abatement, your request may be denied if incomplete, vague, or submitted too late. Avoiding the following errors can significantly improve your chances of success when seeking penalty relief from the South Dakota Department of Revenue.

Missing the 60-Day Deadline

South Dakota generally gives taxpayers 60 days from the date on the notice to appeal a tax penalty. If you miss this window, you may lose your right to request abatement or file a formal appeal.

Providing Vague or Unsupported Claims

Saying you “had a difficult year” or “didn’t know about the rules” is not enough. You must provide specific reasons and include supporting documentation—such as proof of a natural disaster, illness, or incorrect IRS charges.

Failing to Cite Legal Statutes

Referencing the correct laws—like SDCL 10-59-28 or 10-59-31—shows that you've done your research and strengthens the credibility of your claim.

Submitting Disorganized or Multiple Letters

Sending multiple fragmented requests can lead to confusion and delays. Instead, submit one comprehensive, well-organized letter with all required attachments.

Not Keeping Copies or Records

Always save copies of your request letter, proof of mailing, and any communication with the department. These may be essential if you need to appeal or verify your submission.

Avoiding these mistakes will make your request more professional and help ensure it receives the attention and consideration it deserves.

Frequently Asked Questions

Does South Dakota offer first-time penalty abatement like the IRS?

No, South Dakota does not offer an automatic “First-Time Abate” program like the IRS. Instead, each request is reviewed on a case-by-case basis. To qualify, you must demonstrate reasonable cause or another valid justification, such as a delay caused by the Department. Ensure you include all relevant supporting documentation when submitting your request to strengthen your case.

Can I request abatement for both penalties and interest?

Under SDCL 10-59-28, the South Dakota Department of Revenue may reduce or eliminate penalties and interest if it determines the action is “just and equitable.” Relief may also be granted when departmental negligence contributed to the charges. Requests must include a clear explanation and supporting evidence showing that the penalties or interest were unfairly assessed.

How long does it take to get a decision?

Response times vary based on the complexity of your request. Straightforward cases may be resolved in a few weeks, while more detailed matters can take several months. Suppose you haven’t received a response within 30 days. In that case, following up with the South Dakota Department of Revenue is advisable to ensure your request is processed and to provide any missing information.

Will requesting an abatement trigger a tax audit?

Generally, no. Submitting a properly completed penalty abatement request does not initiate a tax audit. However, if your request contains suspicious, inaccurate, or conflicting information, the Department of Revenue may review your tax records more closely. Ensure that your statements are truthful and your documentation is complete to avoid additional scrutiny.

What if I miss the 60-day deadline to appeal?

Missing the 60-day deadline to appeal may limit your ability to contest the penalty. However, you may still qualify for relief in exceptional cases such as natural disasters, serious illness, or other uncontrollable events. Point out the circumstances behind the delay in your request and provide documentation, if available, to support your explanation.

Should I pay the tax before my abatement request is reviewed?

Paying the underlying tax can help reduce additional interest from accruing while your abatement request is under review. If your penalty or interest is later waived, any overpayment may be refunded or credited to your account. Making timely payment also shows good faith and may support your case for relief.

Is professional help required to submit an abatement request?

No, professional representation is not required, but it can be beneficial. A qualified tax professional—such as an enrolled agent or CPA—can help you prepare a complete and persuasive request, especially if you face significant penalties, multiple years of noncompliance, or a previously denied request. They can also assist with appeals or setting up a payment plan.
