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.
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:
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.
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.
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:
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.
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:
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.
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:
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.
If your county offers a plan, ask for the appropriate forms, which typically include:
Be sure to complete all sections accurately. Errors or incomplete forms may delay processing or disqualify your request.
Most counties require the following documents along with your application:
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.
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.
Missing any payment can lead to default, which will result in the full balance becoming immediately due or disqualifying you from future installment plans.
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:
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.
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:
There is no public web page or form to apply online, so communication typically begins over the phone or by mail.
The Department may ask for additional information to evaluate your request. Required documents may include:
Determining what your business can reasonably pay monthly without defaulting again is the goal.
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.
If the department accepts your proposal, they will send you written confirmation of the payment terms, including:
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.
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.
If you miss a property tax payment while enrolled in an installment plan, you may face the following penalties:
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.
If you default on a payment plan for business taxes with the Department of Revenue, you could face more aggressive measures:
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Save all confirmation emails, payment statements, and copies of your agreement. These documents are essential to resolve a dispute or provide proof of compliance.
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.
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.
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.
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.
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.
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.
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.
