South Dakota’s tax structure stands out from many other states due to the absence of a personal income tax, which appeals to individuals and businesses. However, taxpayers are still responsible for complying with various state and local tax obligations, including sales tax, use tax, contractor’s excise tax, and property taxes. For those unable to pay their full tax liability upfront, the South Dakota Department of Revenue offers payment plans to help manage outstanding balances over time.

A tax payment plan, an installment agreement, enables eligible taxpayers to spread payments over several months rather than paying in a single lump sum. This option can provide much-needed financial relief for working-class households, small business owners, and retirees facing temporary hardship. By making smaller, consistent payments, taxpayers can remain in good standing while meeting their legal obligations without triggering additional penalties.

Acting promptly is essential if you owe South Dakota state taxes. Setting up a payment plan can prevent your account from becoming delinquent and protect you from enforcement actions such as liens or distress warrants. This guide outlines how to apply for a state tax payment plan, the required information, and the key responsibilities for maintaining compliance throughout the agreement.

What Is a South Dakota State Tax Payment Plan?

A South Dakota state tax payment plan, also known as an installment agreement, is a formal arrangement that allows you to pay off a tax bill over time through monthly payments. Instead of paying your whole balance by the original due date, you can split what you owe into manageable installments. This option can help you avoid additional fees, interest, and collection actions if you cannot pay the entire amount simultaneously.

Unlike the IRS, which offers standardized plans for individual income taxpayers, South Dakota's approach is more flexible but fragmented. That’s because there is no single, statewide system for all taxes. Instead, how your payment plan is handled depends on the type of tax you owe:

Types of South Dakota Tax Plans

  • Property Tax Payment Plans
    • Managed at the county level by your county treasurer
    • Available in counties that adopt installment options based on South Dakota Codified Law 10-21-7.1
    • Payments typically span ten months, from January through October
  • Business Tax Payment Arrangements
    • Managed by the South Dakota Department of Revenue
    • Applies to sales tax, contractor’s excise tax, and other state-administered taxes
    • Evaluated case-by-case with no standard structure or web page to apply online

Each type of plan serves the same core purpose: helping taxpayers resolve outstanding tax balances without facing escalating enforcement. However, the rules, deadlines, and processes vary based on the agency involved and the type of tax you owe.

Understanding these differences is essential to request the correct payment agreement and avoid delays, accrued interest, or default.

Who Is Eligible for a Payment Plan?

Not all taxpayers automatically qualify for a South Dakota state tax payment plan. Eligibility depends on several factors, including the type of tax you owe, your compliance history, and whether you meet specific filing and payment requirements. South Dakota handles eligibility differently for property tax installment plans and business tax payment arrangements.

Property Tax Installment Plan Eligibility

You must meet your county treasurer's requirements to qualify for a property tax payment plan. While specific terms may vary by county, most follow the same basic criteria:

  • You must own property in a county that offers installment plans.
  • Your current tax year’s bill must be eligible (plans are typically available only for the upcoming tax year).
  • You must apply by the county’s deadline, often December 15 of the prior year.
  • Your property taxes from previous years must be fully paid—no delinquent property taxes are allowed.
  • You must agree to make monthly payments automatically (ACH withdrawals from a checking account).

These plans are typically structured as ten equal monthly payments, beginning in January and ending with a final payment in October. Meeting these eligibility requirements allows most taxpayers to spread their property tax payments without facing accrued penalties.

Business Tax Payment Arrangement Eligibility

The South Dakota Department of Revenue reviews each business tax payment plan request on a case-by-case basis. Unlike plans for paying property taxes in installments, there is no formal checklist—but the following factors are typically considered:

  • All tax returns must be filed, even if you cannot pay in full.
  • You must show financial hardship or limited ability to pay your full balance.
  • Your payment history and prior compliance with filing requirements will be reviewed.
  • You must propose a realistic monthly payment amount that fits your current financial situation.

Because there’s no standard form or payment plan online portal for business taxes, the department may also ask for additional information, such as a financial statement, account balances, or an explanation of hardship.

Your chances of approval will rise if you are proactive and transparent.

How to Apply for a Property Tax Payment Plan

If you own property in South Dakota and want to pay your property taxes in monthly installments, you can set up a payment plan for your property taxes with your county treasurer. However, this option is only available in counties that offer installment agreements under South Dakota Codified Law 10-21-7.1, and you must follow specific application steps and deadlines to qualify.

Here’s how to apply:

1. Contact Your County Treasurer’s Office

Before you begin the process, visit your county treasurer to confirm whether they offer a monthly payment plan. Not all counties in South Dakota participate, and eligibility can depend on your property’s assessed value and tax status. Some counties may also provide application instructions on their official web page.

2. Request and Complete the Application

If your county offers a plan, ask for the appropriate forms, which typically include:

  • The ACH Authorization Form allows the county to withdraw funds directly from your checking account.
  • Property Information Form – Includes parcel ID, property address, and owner contact details.

Be sure to complete all sections accurately. Errors or incomplete forms may delay processing or disqualify your request.

3. Gather Supporting Documents

Most counties require the following documents along with your application:

  • Voided check or a bank statement showing your routing and account numbers
  • Proof of property ownership (may be verified internally by the county)
  • Valid contact information for communication about your plan

4. Submit Before the Deadline

To be eligible for the upcoming tax year, you must typically submit your application by December 15 of the current year. This applies to plans beginning in January of the following year. Late applications are usually not accepted, regardless of circumstances.

5. Confirm Enrollment and Payment Dates

After submitting your application, follow up with the county treasurer’s office to confirm approval. Most counties divide your property tax bill into ten equal monthly payments, which are withdrawn automatically from January through October. You will receive a schedule with exact payment dates and amounts.

Example: Pennington County Payment Schedule

  • January
    • Payment Amount: $XXX.XX
    • Payment Method: ACH (automatic)
  • February
    • Payment Amount: $XXX.XX
    • Payment Method: ACH (automatic)
  • March–September
    • Payment Amount: $XXX.XX per month
    • Payment Method: ACH (automatic)
  • October
    • Payment Amount: $XXX.XX
    • Payment Method: Final payment

Missing any payment can lead to default, which will result in the full balance becoming immediately due or disqualifying you from future installment plans.

How to Request a Business Tax Payment Arrangement

Suppose your business owes South Dakota state taxes, such as sales or contractor excise tax, and you cannot pay the full amount by the due date. In that case, you may qualify for a tax payment plan for your business through the South Dakota Department of Revenue. Unlike property tax plans, these are not standardized and are handled on a case-by-case basis. Here’s how to start the process:

1. File All Required Tax Returns

Before the department considers a payment agreement, your business must be current on all tax filings and submit all required returns, even if you cannot pay. Failing to do so may result in penalties, delayed processing, or automatic denial.

2. Contact the Department of Revenue Directly

Call the Department at 1-800-829-9188 or use the contact information on your tax bill or notice to begin the process. Be prepared to explain:

  • Why are you unable to pay the full amount
  • What caused the financial hardship (if applicable)
  • Your plan to pay down the balance over time

There is no public web page or form to apply online, so communication typically begins over the phone or by mail.

3. Provide Financial Documentation

The Department may ask for additional information to evaluate your request. Required documents may include:

  • A financial statement outlining current income and expenses
  • Bank account balances and liabilities
  • A proposed monthly payment amount
  • An explanation of hardship (if you're requesting special terms)

Determining what your business can reasonably pay monthly without defaulting again is the goal.

4. Propose a Realistic Payment Plan

When discussing your installment agreement, suggest a monthly payment that fits your business’s cash flow. Avoid overpromising. Unrealistic amounts often lead to default and may restart the collection process. Typically, no down payment is required, but the Department will expect consistent automatic payments or checks once the agreement is finalized.

5. Finalize the Agreement

If the department accepts your proposal, they will send you written confirmation of the payment terms, including:

  • Payment due dates
  • Total payment amount
  • Accepted payment methods (e.g., ACH, credit card, or check)
  • Any interest or fees that will continue to accrue during the plan

Read the agreement carefully before you sign and submit it. Keep a copy for your account records.

Payment Methods and Processing Times

Once your payment plan is approved—whether for property or business taxes—you’ll need to understand how and when to make payments. South Dakota tax authorities offer several payment methods, each with a processing timeline and requirements.

Accepted Payment Methods

  • ACH Debit: Funds automatically withdrawn from your checking account on scheduled dates. This is the standard method for installment property tax payments and is often used for business taxes.
  • ACH Credit: You initiate the transfer through your bank. This method is standard for businesses that manually handle their payments or use accounting software.
  • Credit or Debit Card: Payments can be made using Visa, MasterCard, or Discover. A processing fee may apply.
  • Check or Money Order: Depending on your plan, payments sent by mail must be addressed to the appropriate county treasurer or the South Dakota Department of Revenue.

Payment Methods and Processing Times

ACH Debit

  • Processing Time: 2–3 business days
  • Notes: Ensure funds are available in your account before withdrawal to avoid failed payments.

ACH Credit

  • Processing Time: 1–2 business days
  • Notes: Initiate the transfer early to ensure it is received by the due date.

Credit/Debit Card

  • Processing Time: Immediate to 2 business days
  • Notes: Additional fees may apply when using a credit or debit card to make a payment.

Check or Money Order

  • Processing Time: 7–10 business days
  • Notes: Mail early to avoid late payment penalties. Payments are only considered on time when received, not when sent.

Tips to Avoid Payment Issues

  • Verify your account information when setting up automatic payments.
  • Set calendar reminders for each scheduled withdrawal.
  • Send checks in advance to guarantee they arrive before the payment due date.
  • Keep records of every statement, confirmation number, or email you receive.

Consequences of Missing a Payment

Failing to make a scheduled payment under a tax payment plan in South Dakota can lead to serious consequences. Whether enrolled in a property tax installment plan or a business tax payment arrangement, missing a monthly payment may cause your agreement to default, triggering additional fees, interest, and legal enforcement actions.

Property Tax Defaults

If you miss a property tax payment while enrolled in an installment plan, you may face the following penalties:

  • Termination of the plan: The county treasurer may cancel your agreement, making the full balance immediately due.
  • Disqualification from plans: You may lose eligibility for installment plans in upcoming tax years.
  • Accrued interest: If your account becomes delinquent, counties may assess interest at up to 10% annually.
  • Tax deed action: Substantial delinquent property taxes may lead to the county initiating tax deed proceedings, which could eventually result in the property being seized and sold.

Each county has discretion under South Dakota Codified Law 10-21-7.1 to enforce these penalties. Read your county’s agreement carefully and take action before a missed payment causes a default.

Business Tax Defaults

If you default on a payment plan for business taxes with the Department of Revenue, you could face more aggressive measures:

  • Immediate demand for full payment of the remaining tax balance
  • Penalty of 10% of the liability (minimum $10), plus 1% monthly interest on the unpaid amount
  • Tax liens filed with your county’s Register of Deeds
  • Distress warrants authorizing the sheriff to seize and sell personal property
  • Revocation of business licenses, which could impact your ability to operate
  • In severe cases, criminal penalties may apply for willful non-compliance

These consequences are supported by South Dakota Codified Law 10-59-10, which grants the state authority to collect unpaid taxes through liens, levies, and legal proceedings.

Contact your tax authority immediately if you cannot make a scheduled payment. Some counties or the Department of Revenue may be willing to adjust your payment plan if you act before default occurs.

Timeline of Enforcement Actions

When a taxpayer misses a payment and does not resolve the issue, South Dakota’s tax authorities may begin enforcement actions. The purpose of these actions is to recover unpaid tax balances, and the escalation process can occur quickly, particularly for business taxes. Understanding the timeline can help you take timely steps to avoid penalties, fees, and property loss.

1. Initial Default Notice

  • You will typically receive a written notice after a missed payment.
  • The notice may include a grace period to cure the default by paying the overdue amount.

2. Demand for Full Payment

  • If no action is taken, a formal demand for payment is issued.
  • This demand requires payment in full, including any accrued penalties and interest.

3. Tax Lien Filing

  • A tax lien may be recorded with the county Register of Deeds, impacting your credit and ability to sell or refinance property.

4. Distress Warrant

  • The Department of Revenue may issue a distress warrant, which authorizes the sheriff to seize assets, including bank accounts or equipment.

5. Advanced Enforcement

  • Additional actions may include:
    • Collection agency referrals
    • Revocation of licenses
    • Legal action or criminal investigation in extreme cases

Proactive communication can help you avoid enforcement altogether. If you receive a notice, contact the relevant department or county office immediately to discuss your options.

Common Mistakes to Avoid

Many taxpayers unintentionally make errors when applying for or maintaining a tax payment plan in South Dakota. These mistakes can lead to delays, denied applications, or even default—causing additional fees, interest, and collection actions. Awareness of common pitfalls can help you complete your application correctly and protect your standing with the Department of Revenue or your county treasurer.

Submitting Late Applications

Some counties require that property tax payment plan applications be submitted by December 15 of the current year for the upcoming tax year. Submitting after the deadline often results in automatic rejection, with no option to appeal.

Providing Incomplete Banking Information

Most installment plans require automatic payments via ACH debit from a checking account. If you fail to include your account number, routing number, or a voided check, your application may face delays or rejection.

Proposing Unrealistic Payment Terms

When requesting a business tax payment plan, avoid suggesting payment amounts your business cannot realistically maintain. Overpromising often leads to default, additional penalties, and loss of eligibility.

Failing to File Required Returns

You must file all required tax returns, even if you can’t pay in full. Missing returns can make you ineligible for an individual payment plan and may lead to accrued penalties.

Ignoring Official Communications

Always respond to letters or emails requesting additional information. Ignoring outreach from tax authorities can result in application rejection or enforcement actions against your account.

Tips for Staying Compliant on Your Payment Plan

Once your South Dakota tax payment plan is approved, staying compliant is essential to avoid default, penalties, and potential collection actions. Whether on a property tax installment plan or a business tax agreement, consistent account management can help you stay in good standing and avoid surprises.

Set Calendar Reminders

Mark each payment due date on your calendar or mobile device. Most installment plans follow a monthly schedule, and missing even one payment may trigger interest or cancel your agreement.

Monitor Your Bank Account

Ensure sufficient funds are in your checking account on scheduled withdrawal dates. Failed automatic payments may result in late fees, plan termination, and accrued penalties.

Update Your Contact Information

Notify the Department of Revenue or your county treasurer if your mailing address, phone number, or email changes. This ensures you don’t miss important updates or reminders about your payment plan.

File and Pay Current Taxes on Time

Your installment agreement does not exempt you from keeping up with new tax obligations. If you must submit combined tax filings or quarterly returns, please ensure they are filed and paid on time.

Keep Records and Statements

Save all confirmation emails, payment statements, and copies of your agreement. These documents are essential to resolve a dispute or provide proof of compliance.

When to Consider Professional Help

While many taxpayers can manage a South Dakota state tax payment plan on their own, there are situations where working with a tax professional may be the smarter, safer option. If your case involves multiple tax years, large balances, or ongoing collection actions, expert guidance can help you protect your finances and avoid costly mistakes.

Signs You May Need Assistance

  • You have unfiled tax returns for multiple years.
  • Your tax bill exceeds $10,000, and you're unsure how much you can pay monthly.
  • You're facing enforcement actions, such as a tax lien or distress warrant.
  • You’re struggling to understand complex business tax obligations or rules.

How a Tax Professional Can Help

  • Estimate a reasonable payment amount based on your finances.
  • Help you submit complete, accurate paperwork to avoid delays or rejections.
  • Negotiate directly with the Department of Revenue or your county treasurer.
  • Advise on saving money, reducing interest, or avoiding accrued penalties.
  • Represent you if your case escalates to legal or audit-related issues.

Don’t Wait Until Enforcement Begins

Seeking help early—before your account becomes delinquent or legal actions are initiated—can make a significant difference. The sooner you address your tax debt, the more options you’ll have to resolve it responsibly.

Frequently Asked Questions

Can I enroll in a payment agreement if I owe taxes from previous years?

Yes, but eligibility depends on the type of tax. Most counties require prior-year balances to be paid in full for property taxes before approving a new agreement. For business taxes, the South Dakota Department of Revenue may authorize a broader payment plan if all past-due returns are filed and you agree to comply with updated terms. Always confirm with the relevant authority before applying.

What happens if I miss a single installment payment?

Missing one payment can result in serious consequences. The agreement may be canceled for property taxes, and the full amount could become due immediately. Interest and penalties may accrue for business taxes, and collection actions may resume. Contact the Department of Revenue or your county treasurer as soon as possible to explain your situation and request options to prevent default or escalation.

Can South Dakota garnish wages or enforce collections during a payment plan?

If your agreement defaults, the Department of Revenue may initiate collection measures, including wage garnishment, bank levies, or distress warrants. Maintaining timely payments and compliance with your agreement is essential to avoid enforcement. The state typically suspends collection efforts as long as your plan is active and in good standing.

Will the department stop collections once I sign a payment agreement?

Yes, the Department of Revenue generally pauses active enforcement once you enter a valid payment agreement and begin making timely payments. However, if you miss a due date or violate other terms, the contract may be canceled, and collection actions can resume. To remain protected, always meet your installment obligations and notify the department of any issues in advance.

Are there other relief programs besides an individual payment plan?

Yes, in addition to payment plans, South Dakota offers separate property tax relief programs for eligible seniors and low-income individuals. These programs may reduce your overall property tax burden based on income or other qualifying factors. They are administered at the county level, so you should contact your local treasurer’s office to learn more and determine if you qualify.
