Why You Need a South Dakota Sales Tax Registration
South Dakota Sales Tax Registration is required under South Dakota Codified Laws (SDCL) Chapter 10-45, which governs the state's sales and use tax. Any business selling taxable goods or services — including prepared food, beverages, and catering — must register with the South Dakota Department of Revenue before making its first taxable sale. Aberdeen restaurants fall under the same statewide obligation, with no local exemption: operating without a valid sales tax license is a violation of SDCL § 10-45-27, which requires registration prior to conducting business. The Department of Revenue enforces this requirement through its Business Tax Division, and registration is a prerequisite for obtaining other local operating permits in many South Dakota municipalities.
Failing to register or maintain your sales tax license exposes your Aberdeen restaurant to significant legal and operational consequences. The Department of Revenue can assess back taxes on all unregistered sales, compounding the financial burden quickly. Documented penalties and risks include:
- Late filing and payment penalties of typically 1–5% per month on unpaid tax balances, per SDCL § 10-59-6
- Accruing interest on outstanding tax liabilities until the balance is paid in full
- License revocation — the Department of Revenue can revoke your sales tax license for persistent non-compliance, effectively forcing your restaurant to cease taxable sales
- Cease-and-desist orders and potential court action for continued operation without a valid license
- Criminal prosecution for willful tax fraud or evasion under SDCL § 10-59-16, which can result in misdemeanor or felony charges depending on the amount involved
- Lease and insurance complications — many commercial landlords and business insurance providers require proof of all active tax registrations; a lapse can trigger default clauses or coverage disputes

16 of 19 auto-filledBusiness Legal Name
textEnter the exact legal name of your business as it appears on your Articles of Incorporation, LLC Operating Agreement, or — for sole proprietors — your full personal legal name as it appears on your Social Security card or government-issued ID.
COMMON MISTAKE: Entering a DBA (trade name) or shortened version of the business name instead of the full registered legal name — the South Dakota Department of Revenue will cross-reference this against Secretary of State records, and a mismatch causes automatic rejection.
Business Ownership Structure
textIndicate the legal structure of your business: Sole Proprietorship, Partnership, LLC, S-Corporation, C-Corporation, or Non-Profit — use the exact category that matches your formation documents or federal tax classification.
COMMON MISTAKE: Selecting 'LLC' when the business is actually taxed as an S-Corporation at the federal level; the ownership structure here should reflect your legal entity type, not your federal tax election, unless the form specifically asks for tax classification.
Business Start Date
textEnter the date your business first began or will begin making sales subject to South Dakota sales tax, formatted as MM/DD/YYYY — this is the date you opened (or plan to open) for business in South Dakota, not the date you incorporated or formed the entity.
COMMON MISTAKE: Entering your LLC or corporation formation date instead of the actual first date of taxable sales activity; the Department of Revenue uses this date to determine your first filing period, and an incorrect date can misalign your reporting obligations.
Description of Business Activities
textProvide a concise, specific description of what your business sells or the services it provides — for a restaurant, this should include both food and beverage sales and any taxable services such as catering, specifying whether you operate dine-in, takeout, delivery, or a combination.
COMMON MISTAKE: Writing vague descriptions like 'food service' or 'restaurant' without specifying the types of taxable transactions; the Department of Revenue may flag incomplete descriptions for follow-up, delaying your license issuance.
Owner/Applicant Full Legal Name
textEnter the full legal name of the individual owner, principal officer, or authorized representative completing this application — for sole proprietors this is your personal legal name; for corporations or LLCs, enter the name of the officer or member authorized to act on behalf of the entity.
COMMON MISTAKE: Entering a nickname, middle-name-only variant, or the business name in the owner name field instead of the full legal personal name, which will cause a mismatch when the Department of Revenue verifies identity against SSN or EIN records.
Tax ID Type (SSN or EIN)
textIndicate whether the tax identification number you are providing is a Social Security Number (SSN) or an Employer Identification Number (EIN) — sole proprietors without employees may use their SSN, while partnerships, corporations, LLCs with employees, or multi-member LLCs must use an EIN.
COMMON MISTAKE: Selecting SSN for a multi-member LLC or corporation, which does not align with IRS entity classification requirements and will create a discrepancy during the Department of Revenue's federal tax record cross-check.
Owner Social Security Number
textEnter the nine-digit Social Security Number of the individual owner or sole proprietor in the format XXX-XX-XXXX — this field is required for identity verification and tax compliance purposes under South Dakota Codified Laws Chapter 10-45.
COMMON MISTAKE: Entering the business EIN in this field instead of the owner's personal SSN, or omitting hyphens when the form requires the XXX-XX-XXXX format — either error triggers a processing hold.
Federal Tax Identification Number
textOn page 2 of the application, this second instance of the Federal Tax Identification Number field is populated with the business EIN — enter the same XX-XXXXXXX formatted EIN you provided for the Business EIN field above to ensure consistency across both references in the form.
COMMON MISTAKE: Entering a different number in this field than in the Business EIN field above — inconsistency between the two Federal Tax Identification Number fields on the same application is a common source of processing errors and will delay approval.
Business Employer Identification Number
textEnter your business's nine-digit Employer Identification Number issued by the IRS in the format XX-XXXXXXX — this is required for all entities other than sole proprietors filing under their personal SSN, and must match the EIN on your IRS CP 575 confirmation letter.
COMMON MISTAKE: Entering an EIN from a prior or related business entity instead of the EIN specifically assigned to the business being registered — each registered business location or entity must use its own unique EIN.
Federal Tax Identification Number
textOn page 2 of the application, this second instance of the Federal Tax Identification Number field is populated with the business EIN — enter the same XX-XXXXXXX formatted EIN you provided for the Business EIN field above to ensure consistency across both references in the form.
COMMON MISTAKE: Entering a different number in this field than in the Business EIN field above — inconsistency between the two Federal Tax Identification Number fields on the same application is a common source of processing errors and will delay approval.

Top 5 South Dakota Sales Tax Registration Mistakes
1. Entering the Wrong Business Start Date
Applicants frequently enter their LLC formation date or lease signing date instead of the actual date they first made — or expect to make — taxable sales in South Dakota. The Department of Revenue uses this date to determine your first filing period, so an incorrect date can result in missed filing deadlines or penalty notices for periods you weren't actually operating. Enter the date you realistically expect to open for business and make your first taxable sale — not the date you signed your lease or incorporated.
2. Selecting the Wrong Business Entity Type
Choosing 'Sole Proprietor' when the business is registered as an LLC — or vice versa — is one of the most common errors on the South Dakota EPath registration portal, and it requires a full correction submission that can add 1–2 weeks to your approval timeline. Your entity type must exactly match what is on file with the South Dakota Secretary of State. For example, a single-member LLC should be registered as an LLC, not as a sole proprietor, even if you are the only owner.
3. Using a Home Address Instead of the Restaurant's Physical Location
Aberdeen restaurants operating out of a commercial space must list the physical street address of the restaurant — not the owner's home address or a PO Box — as the business location. The Department of Revenue uses the physical address to assign the correct municipal sales tax rate (Aberdeen levies a 2% municipal tax on top of the 4.5% state rate), and an incorrect address can result in your business being assigned the wrong tax rate. Double-check that the address matches your Certificate of Occupancy or lease agreement exactly, including suite numbers.

Gather Required Information and Documents
Collect your Social Security Number or Federal Employer Identification Number (EIN), restaurant's legal name, physical address in Aberdeen, mailing address, and description of business activities (food service, catering, retail, etc.). You'll also need your ownership structure (sole proprietor, LLC, corporation) and the date you plan to begin operations. Have this information ready before starting the online application — most applicants take 15–20 minutes to locate all required details.

See All RequirementsProcessing time varies depending on whether you apply online or by mail, per the South Dakota Department of Revenue & Regulation website. Online applications typically process within 1–3 business days, while paper applications may take 5–10 business days. Before you can legally operate your restaurant, you'll also need to complete your City Business License/Registration, which has its own separate timeline.
South Dakota does not charge a filing fee for sales tax registration — the application itself is free, as stated on the Department of Revenue & Regulation's registration page. However, you may incur costs for any required documentation (such as copies of your articles of incorporation or EIN letter) or for obtaining an Application for Employer Identification Number if you don't already have one. Not legal advice — verify current fees with the South Dakota Department of Revenue & Regulation.
No — South Dakota sales tax registrations are tied to a specific business location and cannot be transferred. If you relocate your restaurant, you must apply for a new sales tax registration certificate for the new address and notify the Department of Revenue & Regulation of the closure of your old location, per their guidance on business changes. You will also need to apply for a new City Business License/Registration at your new Aberdeen location.
South Dakota does not require periodic renewal of your sales tax registration certificate — once issued, it remains valid as long as your business operates at that location and you remain in compliance with filing and payment obligations. You must, however, file sales tax returns on a regular schedule (typically monthly or quarterly, depending on your sales volume), as outlined by the Department of Revenue & Regulation. Contact the South Dakota Department of Revenue & Regulation to confirm your specific filing frequency.
South Dakota does not conduct mandatory inspections as part of the sales tax registration process itself — the application is administrative and does not involve a site visit. However, once you receive your registration, the Department of Revenue & Regulation may conduct compliance audits or inspections at any time to verify sales reporting and tax payment accuracy. Before opening, you will be subject to separate health and safety inspections from the city; consult your Certificate of Occupancy requirements for details.
