Why You Need a South Dakota Sales Tax Registration
Any business selling tangible personal property or taxable services in Aberdeen is required to collect and remit South Dakota sales tax under South Dakota Codified Laws (SDCL) Chapter 10-45, the state's Retail Sales and Service Tax statute. The South Dakota Department of Revenue administers all sales tax registrations and enforces compliance statewide — there is no separate Aberdeen municipal registration layer, so your state-level license covers your Brown County location. Before you ring up your first customer, SDCL § 10-45-27 requires you to hold a valid sales tax license; operating without one is a violation from day one, not just at audit time.
Failing to register or maintain your South Dakota Sales Tax License exposes your Aberdeen restaurant to a cascade of financial and operational consequences. The Department of Revenue can act quickly once non-compliance is identified:
- Late filing and late payment penalties of typically 1–5% of tax owed per month, accruing until the balance is resolved
- Statutory interest charges on unpaid tax balances, compounding over time
- License revocation for persistent non-compliance, which legally prohibits continued sales activity
- Criminal prosecution for willful tax fraud or evasion under SDCL § 10-59-6
- Lease and financing complications — most commercial landlords and SBA lenders require proof of a current tax license before executing or renewing agreements
Not legal advice — verify current penalty schedules with the South Dakota Department of Revenue.
Legal code: State tax code, sales/use tax statutes, withholding requirements
Recent update: As of 2023, South Dakota eliminated its economic nexus transaction threshold (the previous 200-transaction trigger), meaning remote sellers are now subject to sales tax obligations based solely on the dollar threshold under SDCL § 10-64 — but for Aberdeen brick-and-mortar restaurant operators, physical presence means you have been required to register from the day you opened, with no threshold exemption available. Contact the South Dakota Department of Revenue to confirm any rule updates in effect for 2026.
Who Needs a South Dakota Sales Tax Registration?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Full-service restaurants selling prepared food and beverages in South Dakota must register for a sales tax license under SDCL § 10-45-27, as all sales of prepared food are subject to the state sales tax rate (currently 4.2% as of 2023 reduction) plus applicable municipal taxes. |
| Bar / Nightclub | Required | Bars and nightclubs selling alcoholic beverages and any food items are required to hold a South Dakota sales tax license under SDCL § 10-45-2, as gross receipts from alcohol and food sales are taxable retail transactions. |
| Food Truck | Required | Food trucks selling prepared food in South Dakota — including those operating in Aberdeen — must register for a sales tax license under SDCL § 10-45-27 regardless of whether they operate at a fixed location, as the point-of-sale determines nexus, not a permanent address. |
| Coffee Shop / Café | Required | Coffee shops and cafés selling prepared beverages and food items are subject to South Dakota sales tax under SDCL § 10-45-2, as prepared drinks (including coffee beverages) are classified as taxable prepared food under state law. |

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 legal birth name; this must match your South Dakota Secretary of State registration precisely.
COMMON MISTAKE: Entering a DBA (trade name) or shortened nickname instead of the full registered legal name causes mismatches with Secretary of State records and triggers manual review delays.
Business Ownership Structure
textEnter the legal entity type that matches your formation documents: choose from Sole Proprietorship, Partnership, LLC, S-Corporation, C-Corporation, or Nonprofit — the South Dakota Department of Revenue uses this to determine which tax ID fields are required downstream.
COMMON MISTAKE: Selecting 'LLC' when the business is actually a sole proprietor operating under an assumed name, or vice versa, creates a tax ID mismatch that stalls the application.
Business Start Date
textEnter the date your business first began — or will begin — conducting taxable sales in South Dakota, formatted as MM/DD/YYYY; this date determines your first filing period and back-tax liability window.
COMMON MISTAKE: Using the date you filed formation documents with the Secretary of State instead of the actual first date of taxable sales activity — these are often different dates and the Department of Revenue audits for consistency.
Description of Business Activities
textWrite a concise, specific description of what your business sells or does — for a restaurant, enter something like 'Retail sale of prepared food and non-alcoholic beverages for on-premises and take-out consumption'; vague entries like 'food service' or 'restaurant' alone can delay the classification review.
COMMON MISTAKE: Entering only a business category (e.g., 'restaurant') without specifying the taxable transaction type can cause the Department of Revenue to request clarification, adding processing time.
Owner/Applicant Full Legal Name
textEnter the full legal name of the individual owner, officer, or authorized representative signing the application — this must match government-issued ID and, for entities, the name listed on Secretary of State filings.
COMMON MISTAKE: Using a nickname, middle-name variation, or the business name in this field instead of the individual's legal name causes a signature verification failure.
Tax ID Type (SSN or EIN)
textIndicate whether the primary tax identifier being submitted is a Social Security Number (SSN) or Employer Identification Number (EIN) — sole proprietors with no employees typically use SSN, while all other entity types must use an EIN issued by the IRS.
COMMON MISTAKE: Sole proprietors checking 'EIN' when they only have an SSN — or multi-member LLCs checking 'SSN' — creates a downstream field conflict that the Department of Revenue flags for correction.
Owner Social Security Number
textEnter the 9-digit Social Security Number of the individual owner in the format XXX-XX-XXXX; this field is required for sole proprietors and may be required alongside an EIN for single-member LLCs depending on the entity's federal tax classification.
COMMON MISTAKE: Leaving this field blank because you also have an EIN — South Dakota requires owner SSN for identity verification on sole proprietorships regardless of whether an EIN exists.
Federal Tax Identification Number
textOn page 2 of the application, this second instance of the Federal Tax ID field should reflect the business EIN (not the owner SSN); enter the same XX-XXXXXXX value as the Business EIN field directly above it to ensure internal consistency across the document.
COMMON MISTAKE: Leaving this field blank because the EIN was already entered in the field above — both fields must be completed independently or the form fails validation; duplicating the correct value is required.
Business Employer Identification Number
textEnter the 9-digit EIN assigned to your business entity by the IRS, formatted as XX-XXXXXXX; this is required for all entities other than sole proprietors who have not obtained an EIN, and must match your IRS CP-575 or 147C confirmation letter exactly.
COMMON MISTAKE: Entering the owner's personal SSN in this field instead of the business EIN — these are distinct numbers and the mismatch will cause the application to be rejected or held for clarification.
Federal Tax Identification Number
textOn page 2 of the application, this second instance of the Federal Tax ID field should reflect the business EIN (not the owner SSN); enter the same XX-XXXXXXX value as the Business EIN field directly above it to ensure internal consistency across the document.
COMMON MISTAKE: Leaving this field blank because the EIN was already entered in the field above — both fields must be completed independently or the form fails validation; duplicating the correct value is required.

Top 5 South Dakota Sales Tax Registration Mistakes
1. Entering the Wrong Business Entity Type
Selecting 'Sole Proprietor' when your Aberdeen restaurant is registered as an LLC or corporation causes a mismatch between your sales tax license and your Secretary of State business registration — the Department of Revenue will flag the discrepancy and request a corrected filing. For example, entering 'John Smith' as the business name instead of 'Smith Eats LLC' will trigger a rejection. Before you begin, confirm your exact legal entity type on your South Dakota Secretary of State certificate and use that name verbatim on the application.
2. Using a Home Address Instead of the Restaurant's Physical Location
South Dakota requires the physical street address of each business location where taxable sales occur — a P.O. Box or your personal home address will cause the application to be returned as incomplete. A common example: entering '123 Main St, Aberdeen, SD 57401' (your home) instead of '456 Sixth Ave S, Aberdeen, SD 57401' (the restaurant). The Department of Revenue ties your license to a specific location, so even a minor address error can add 2–3 weeks to your timeline while the correction is processed.
3. Leaving the NAICS/Business Activity Code Blank or Incorrect
The South Dakota sales tax application requires you to classify your business activity using a NAICS code; restaurants typically use 722511 (Full-Service Restaurants) or 722513 (Limited-Service Restaurants), but applicants frequently leave this field blank or enter a generic retail code. An incorrect code can result in your account being set up under the wrong tax rate schedule, which creates audit exposure down the line. Look up your correct NAICS code at census.gov/naics before completing this field.

See All RequirementsProcessing timelines vary depending on application completeness and South Dakota Department of Revenue workload; most applicants receive approval within 1–3 business days if submitted online through the department's system, though mail submissions may take longer. To ensure faster processing, complete all required fields accurately and have your federal Application for Employer Identification Number (EIN) ready before filing. Contact the South Dakota Department of Revenue at 605-773-3311 or check their website for current processing times.
South Dakota does not charge a government filing fee for sales tax registration—the application itself is free. However, you may incur costs for obtaining a federal Application for Employer Identification Number (EIN) if you do not already have one, which is also free from the IRS. You will also need to obtain an Aberdeen City Business License/Registration, which may have associated municipal fees; contact the City of Aberdeen for those details. Not legal advice—verify current fees with the South Dakota Department of Revenue and Aberdeen city offices.
A sales tax registration is tied to a specific business location and registration number; if you relocate your restaurant, you must notify the South Dakota Department of Revenue of the address change or apply for a new registration for the new location. Most address changes can be handled by contacting the department directly or updating your registration online if you have an existing account. Before relocating, ensure your new location complies with all local zoning and permitting requirements, including obtaining a new Aberdeen Certificate of Occupancy.
South Dakota sales tax registrations do not expire and do not require periodic renewal as long as you remain actively registered and compliant with reporting requirements. However, you must file monthly or quarterly sales tax returns with the South Dakota Department of Revenue based on your reporting schedule; failure to file returns—even if you have no sales—can result in penalties and potential deactivation of your registration. Contact the South Dakota Department of Revenue at 605-773-3311 to confirm your specific filing frequency.
South Dakota does not conduct a mandatory inspection as part of the sales tax registration process—registration is typically a paper or online administrative filing. However, the South Dakota Department of Revenue may conduct compliance audits of your business records, sales tax returns, and inventory at any time; Aberdeen city inspectors may also conduct separate health, safety, or zoning inspections as part of routine compliance checks. To prepare, maintain accurate sales records, keep copies of all filed returns, and ensure your restaurant location complies with all applicable permits, including your Building Permit and health licensing requirements.
