By Jake Lawson, LLC Formation Strategist
South Dakota offers a compelling combination of reasonable formation costs and business-friendly policies that many entrepreneurs overlook. After helping over 1,200 business owners navigate LLC formations across all 50 states, I can tell you that South Dakota’s $150 filing fee and streamlined system provide solid value for the services you receive.
The standout feature? South Dakota offers some unique privacy advantages and asset protection benefits that justify the moderate costs. The challenge? Their recent annual report fee increase and higher foreign LLC registration costs require careful budgeting.
But here’s what makes South Dakota particularly attractive: immediate online approval, comprehensive privacy protections, and a business-friendly regulatory environment that supports long-term growth.
Let me break down every South Dakota LLC cost you’ll encounter, plus my proven strategies for maximizing value while minimizing expenses.

Jake’s assessment: South Dakota’s costs are reasonable for the privacy and business advantages you receive. Their recent annual report increase is noticeable but still competitive nationally.
Breaking Down South Dakota’s Required Costs
Articles of Organization: $150 (One-Time)
South Dakota’s formation fee sits in the middle range compared to other states—not the cheapest, but reasonable for what you get.
What this fee covers:
- Processing your LLC formation documents
- Creating your legal business entity
- Immediate online approval (if filing electronically)
- Official state recognition and certificate
Jake’s perspective: At $150, South Dakota costs more than budget states like Wyoming ($60) but less than premium states like Massachusetts ($520). The value proposition comes from South Dakota’s privacy advantages and business-friendly environment.
Processing options:
- Online filing: Immediate approval
- Mail filing: 1-2 business days plus mail time
South Dakota Annual Report: $55 Online/$70 Mail (Annual)
Recent change alert: South Dakota increased their annual report fee from $50 to $55 (online) effective July 1, 2025.
What’s required:
- Confirm current business information
- Update registered agent if changed
- Verify member/manager details
- Submit by annual deadline
Jake’s take: The $5 increase is unfortunate but still keeps South Dakota competitive. Many states charge $100-$300 for annual reports, so $55 remains reasonable. The $15 mail surcharge encourages online filing, which benefits everyone.
Strategic tip: Always file online to save $15 and get immediate confirmation.
Optional Costs That Provide Value
Registered Agent: $0-$125/Year
South Dakota requires a registered agent, but you have cost-effective options with strategic implications:
Option 1: Self-Service ($0) Requirements:
- South Dakota street address (no P.O. boxes)
- Available during business hours
- Comfortable with public address disclosure
Privacy consideration: Your address becomes part of public records, which may not align with South Dakota’s privacy advantages.
Option 2: Professional Service ($100-$125/year) Benefits:
- Enhanced privacy protection
- Professional document handling
- Consistent availability
- Often includes additional business services
Jake’s recommendation: For South Dakota LLCs, professional registered agent service is particularly valuable because it maximizes the state’s privacy advantages. At $100-125 annually, it’s a strategic investment in confidentiality.
Top choice: Northwest Registered Agent provides excellent South Dakota service and includes a free first year when they handle your formation.
Operating Agreement: $0 (With Smart Planning)
Why you need one in South Dakota:
- Protects LLC liability protections
- Defines ownership and management structure
- Required by banks for business accounts
- Maximizes South Dakota’s legal advantages
Cost options:
- DIY with templates: $0 (we provide quality templates)
- Online services: $50-$200
- Attorney-drafted: $800-$2,500
Jake’s South Dakota strategy: Start with a solid template, then upgrade to attorney-drafted agreements as your business grows or if you’re using South Dakota for sophisticated asset protection planning.
EIN (Federal Tax ID): $0 (Done Right)
The correct way (free):
- Apply directly through IRS.gov
- Takes 10-15 minutes online
- Receive EIN immediately
Avoid the scams: Third-party services charging $50-$300 provide no additional value over the free IRS service.
Truly Optional Costs
DBA/Fictitious Name: $10
South Dakota offers one of the cheapest DBA fees in the nation at just $10.
When you might need a DBA:
- Operating under a name different from your legal LLC name
- Running multiple brands under one LLC
- Marketing under a simplified version of your legal name
Strategic advantage: At $10, South Dakota makes it very affordable to operate multiple brands or test different business names.
Tip: Getting a DBA for your LLC isn’t mandatory. It’s completely optional. Learn more in our article: Do I Need a DBA?
Foreign LLC Registration: $750 Online/$765 Mail
When this applies: If you formed your LLC in another state but want to do business in South Dakota
Jake’s analysis: This is significantly higher than South Dakota’s domestic formation fee, reflecting their preference for in-state incorporation.
Strategic consideration: If you’re considering South Dakota for its advantages, forming domestically rather than as a foreign LLC provides substantial savings.
Business License and Permit Costs: Variable
South Dakota generally has minimal licensing requirements compared to other states.
State-Level Licenses
- Professional licenses: Varies by profession
- Industry-specific permits: Usually reasonable
- Sales tax permits: Free registration
Local Licenses
- Municipal business licenses: $25-$200
- County permits: Varies by location
- Special use permits: Depends on activity
Jake’s budgeting approach: Allocate $100-$300 for initial licensing research and applications. South Dakota’s business-friendly approach keeps most licensing costs reasonable.
