South Dakota LLC Cost Breakdown

An LLC is the most popular business structure for small businesses in South Dakota, and here's why: low filing cost, liability protection, and zero state income tax on business profits.

Formation Costs

  • LLC Articles of Organization: $150 filing fee (South Dakota Secretary of State). Online filings through SOSEnterprise are processed immediately upon payment. Paper filings average 1 to 3 business days.
  • Name Reservation (optional): $25 to reserve your LLC name for 120 days before filing. This locks in your business name while you prepare other documents.
  • Registered Agent (required): Every LLC must maintain a South Dakota registered agent with a physical street address in the state. A registered agent can be yourself (if you live in SD), a business associate, or a commercial registered agent service. Commercial services typically cost $50 to $150 per year.
  • Operating Agreement (recommended): If you prepare this yourself using a template, cost is minimal (often free online). If you hire an attorney, expect $200 to $500.

Ongoing Annual Costs

  • Annual Report: $55, due the first day of your LLC's anniversary month every year. Filing opens two months before the due date.
  • Registered Agent: $50 to $150/year if using a service provider.
  • Business License (if applicable): South Dakota has no general statewide business license fee. However, certain industries require specific licenses (see below).

South Dakota Corporation Costs

If you need the corporate structure for investment or formal governance, here are the costs:

Formation

  • Articles of Incorporation: $150 filing fee (Secretary of State). Online filing is immediate.
  • Corporate Bylaws: Create yourself for free using a template, or hire an attorney ($300 to $600).
  • Registered Agent: Required. Same cost as an LLC: $50 to $150/year for a service provider, or free if you handle it yourself with an in-state address.
  • Initial Board Meeting: No official cost, but may require legal assistance ($200 to $400).

Ongoing

  • Annual Report: $55 (due the first day of your anniversary month).
  • Registered Agent: $50 to $150/year.

Business Licenses and Permits

South Dakota does not require a general statewide business license. However, you must comply with industry-specific requirements:

Sales Tax License

Required if you have a physical location in South Dakota or sell more than $100,000 in gross sales into the state annually. Good news: there is no application fee. Apply online through the South Dakota Department of Revenue at https://apps.sd.gov/rv23cedar/main/main.aspx. State sales tax rate is 4.2%, but many cities add local sales tax (total rates typically range from 5% to 7%).

Industry-Specific Licenses

Certain industries require specialized licenses through the South Dakota Department of Revenue:

  • Alcohol service or retail (Alcoholic Beverage Control)
  • Contractor's excise license (construction work over a threshold)
  • Manufacturing or processing licenses
  • Motor fuel dealer licenses
  • Tobacco sales license
  • Lottery retailer license

Fees vary by industry. Check with the Department of Revenue at https://dor.sd.gov/ to confirm requirements for your specific business.

Professional Licenses

If you offer professional services (real estate, accounting, law, nursing, contracting), you may need a professional license. Contact your respective state licensing board for fees and requirements.

Fictitious Business Name (DBA) Costs

If you operate under a name other than your personal name (for sole proprietorships) or your LLC's official name, you need a DBA filing:

Professional Services and Legal Fees

Many entrepreneurs hire help with formation and compliance. Here are typical costs:

  • Attorney for LLC/Corporation Formation: $300 to $1,000 (or use online services like a DIY template for $50 to $150).
  • CPA or Accountant: $500 to $2,000+ annually for tax planning and bookkeeping, depending on complexity.
  • Registered Agent Service: $50 to $150/year to handle legal service of process.
  • Business Insurance: General liability typically costs $400 to $1,000+ annually, depending on industry and coverage limits.

Initial Operating Expenses (Beyond Formation)

Formation costs are just the beginning. Budget for real startup expenses:

  • Business Address: $0 if using your home, $200 to $500/month for a physical office or mailbox service.
  • Business Insurance: $400 to $1,500+/year depending on industry.
  • Website and Domain: $100 to $500 for setup, then $10 to $20/year for domain registration.
  • Licenses and Permits (industry-specific): $0 to $500+ depending on your field.
  • Equipment and Supplies: Highly variable. Service-based businesses might need just a computer ($500 to $1,500). Retail or manufacturing requires significantly more.
  • Accounting Software: $10 to $50/month (QuickBooks, Wave, FreshBooks, etc.).
  • Business Banking: Most banks offer free business checking accounts in South Dakota.

South Dakota Startup Costs by Business Type

Sole Proprietorship

Formation cost: $0 to $10 (DBA only if needed)

Operating under your personal name requires no state filing. If you use a business name, file a DBA for $10. No annual reports or registered agent required. This is the cheapest structure but offers no liability protection.

LLC

First-year cost: $150 to $300 (formation + registered agent)

Annual cost: $105 to $205 (annual report + registered agent)

Provides liability protection and tax flexibility. This structure is ideal for most small businesses.

S-Corporation or C-Corporation

First-year cost: $150 to $800 (formation, bylaws, registered agent)

Annual cost: $105 to $205 (annual report + registered agent)

Use only if you plan to reinvest profits or pursue investor funding. Most small businesses do not need this structure.

  3. Complete the Articles of Organization (LLC) or Articles of Incorporation (Corporation).

Paper Filing

Print and mail your documents with a check for $150 to the South Dakota Secretary of State. Processing takes 1 to 3 business days. Contact the Secretary of State at https://sdsos.gov/business-services/default.aspx for the current mailing address and required forms.

Annual Compliance: The Ongoing Cost

Every year, your LLC or corporation must file an Annual Report by the first day of your anniversary month. The $55 fee is non-negotiable. Filing is available online and takes just minutes. Missing this deadline can result in administrative dissolution of your business and late fees of $50 to $150.

If you hire a registered agent service, they typically handle this filing as part of their package.

Registered Agent Requirement

Every registered LLC and corporation in South Dakota must continuously maintain a registered agent with a physical street address (not a PO box) in the state. You can act as your own registered agent if you live in South Dakota, which saves the $50 to $150 annual service fee. Otherwise, use a professional registered agent service.

Common Questions About South Dakota Startup Costs

Do I need an attorney to start a business in South Dakota?

No. You can file online yourself for $150. However, an attorney can review your operating agreement, advise on tax structure, and ensure compliance. Consider hiring one if you're unsure about your business structure or have complex ownership arrangements.

Is there a sales tax on services in South Dakota?

Generally, no. South Dakota's 4.2% state sales tax applies to tangible goods, not most services. Some exceptions exist (e.g., certain telecommunications). Confirm with the Department of Revenue if your service is taxable.

Can I use a PO box as my registered agent address?

No. Your registered agent must have a physical street address in South Dakota. A mailbox service or office suite address works, but a PO box does not.

What happens if I miss my annual report deadline?

Your business becomes delinquent 60 days after the due date. Late fees of $50 to $150 accrue. File immediately if you miss the deadline. Continued non-compliance can result in administrative dissolution.
