Why You Need a South Dakota Employer Registration for Unemployment Insurance
The South Dakota Employer Registration for Unemployment Insurance is mandated under South Dakota Codified Laws (SDCL) Chapter 61-1 through 61-7, which governs the state's Reemployment Assistance program. Any business operating in Aberdeen — or anywhere in South Dakota — that employs one or more workers and meets the wage threshold defined under SDCL § 61-1-11 is required to register with the South Dakota Department of Labor and Regulation (DLR), Reemployment Assistance Division. Registration must be completed before you begin paying wages, not after. The DLR uses registration data to assign your employer account number, calculate your contribution rate, and ensure workers you employ are covered if they file an unemployment claim. Failing to register does not exempt you from liability — the DLR can assess back contributions as if you had been registered from your first covered payroll.
Operating without completing your employer registration exposes your Aberdeen restaurant or food service business to a compounding set of legal and financial consequences. The South Dakota DLR actively audits employer payroll records and cross-references IRS filings to identify unregistered employers. Consequences include:
- Penalty assessments on late or unpaid unemployment insurance contributions, calculated as a percentage of the contributions owed, per SDCL § 61-5-22
- Interest charges accruing on any unpaid contribution balances from the date they were originally due
- Fraud penalties if the DLR determines willful misrepresentation or deliberate failure to register, which can include referral for criminal prosecution under SDCL § 61-6-27
- Retroactive liability for all quarters during which you employed covered workers without registration — meaning you could owe contributions, penalties, and interest dating back to your first hire
- Business license and lease complications — many commercial landlords in Aberdeen and lenders financing restaurant buildouts require proof of state tax and payroll compliance, including UI registration, before closing or renewing agreements
- Workers' compensation and insurance implications — some insurers condition coverage or audits on verified payroll tax compliance, which includes UI registration status
Not legal advice — verify current requirements and penalty schedules directly with the South Dakota Department of Labor and Regulation, Reemployment Assistance Division.

Recent update: As of 2024, the South Dakota Department of Labor and Regulation expanded its online employer registration portal, allowing new Aberdeen-area employers to complete initial UI registration and receive their employer account number digitally — contact the DLR Reemployment Assistance Division to confirm current processing times and any updates to contribution rate schedules for your industry classification.
Who Needs a South Dakota Employer Registration for Unemployment Insurance?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Full-service restaurants that pay $1,500 or more in wages in any calendar quarter, or employ one or more workers for any portion of a day in 20 different weeks in a calendar year, must register with the South Dakota Department of Labor and Regulation under SDCL § 61-1-10. |
| Bar / Nightclub | Required | Bars and nightclubs are subject to South Dakota UI employer registration requirements under SDCL § 61-1-10 once they meet the $1,500 quarterly wage threshold or the 20-week employment test, which virtually all operating bars satisfy. |
| Food Truck | Required | Food trucks that employ at least one paid worker and meet the $1,500 quarterly wage threshold are covered employers under SDCL § 61-1-10; sole proprietors with no paid employees are not required to register, but any food truck with staff must do so. |

1. Entering the Wrong Federal Employer Identification Number (FEIN)
Based on ApronPrep's analysis of South Dakota Employer Registration for Unemployment Insurance applications, the single most common rejection trigger is a transposed or incorrect FEIN — for example, entering 45-1234567 instead of 54-1234567. The South Dakota Department of Labor and Regulation cross-checks your FEIN against IRS records, and any mismatch causes an immediate processing hold that typically adds 2–3 weeks to your timeline. Before submitting, verify your FEIN on your IRS EIN confirmation letter (Form CP 575) — not from memory or a bank document.
2. Misclassifying Workers as Independent Contractors
Listing workers as 1099 contractors when South Dakota's ABC test would classify them as employees is one of the most consequential errors on this registration — it can result in back UI tax assessments plus penalties once the Department audits payroll records. A concrete example: a restaurant owner in Aberdeen listing delivery drivers as contractors when those drivers work set schedules and use owner-provided equipment. Review South Dakota Codified Laws § 61-1-11 for the classification criteria before completing the employee count fields, and when in doubt, classify as an employee.
3. Reporting the Incorrect Business Start Date or First Payroll Date
The South Dakota Department of Labor and Regulation uses your 'date wages first paid in South Dakota' to determine your initial UI tax quarter — entering the business formation date instead of the actual first payroll date is a frequent error that results in incorrect tax period assignments and penalty notices. For example, if your LLC was formed January 5 but you paid your first employee March 15, the correct entry is March 15. Check your earliest payroll records or bank statements to confirm the exact date before entering it on the form.

See All RequirementsTimeline varies depending on whether you register online or by mail, per the South Dakota Department of Labor and Regulation website. Online registration through the state's unemployment insurance system typically processes within 1–3 business days, while paper applications may take 5–10 business days. We recommend registering online to minimize delays, especially if you need to coordinate with other requirements like Application for Employer Identification Number or City Business License/Registration, which must be completed before you can legally hire staff.
South Dakota does not charge a government filing fee for employer registration for unemployment insurance—the registration itself is free, per the South Dakota Department of Labor and Regulation. However, you will be responsible for unemployment insurance tax contributions once you begin employing workers; the tax rate is set annually by the state and varies based on your industry and claims history. Contact the South Dakota Department of Labor and Regulation to confirm current tax rates and contribution schedules. Not legal advice.
No, you cannot simply transfer your registration to a new location—you must register as a new employer with the South Dakota Department of Labor and Regulation if you relocate your restaurant, per state unemployment insurance rules. Your current account will remain tied to your original business address and employer identification number (EIN). If you move, contact the department to discuss closing your current account and opening a new one; you may also need to update your City Business License/Registration with Aberdeen to reflect the new location.
Your South Dakota employer registration for unemployment insurance does not require renewal—it remains active as long as your business is operating and you continue paying unemployment insurance taxes, per the South Dakota Department of Labor and Regulation. However, you must file quarterly wage reports and pay taxes on schedule; failure to do so will result in penalties and potential account deactivation. Contact the department if your business status changes (closure, sale, or acquisition) to update your account.
There is no formal inspection associated with employer registration for unemployment insurance—this requirement is administrative only and does not involve a physical inspection of your restaurant, per the South Dakota Department of Labor and Regulation. The department may conduct payroll audits or compliance reviews to verify that you are correctly reporting wages and paying taxes, but these are typically conducted remotely or by mail. Maintain accurate payroll records and wage documentation to prepare for any future audit; this also helps you stay compliant with other requirements like E-Verify Enrollment and EFTPS reporting.
