Review total first-year and annual costs
The calculator breaks down initial formation costs versus ongoing annual maintenance costs. Year 1 is typically the most expensive due to one-time filing and setup fees.
Example Calculation
Let's calculate the cost to form and maintain an LLC in South Dakota.
Forming a single-member LLC in South Dakota: state filing fee $150, registered agent service (~$125/year), EIN from IRS (free), and a DIY operating agreement (free, or $500-$1,500 with an attorney). South Dakota's annual report/franchise tax is $55/year.
Result: Year 1 total: approximately $275 (plus any optional attorney fees). Ongoing annual cost: approximately $180/year. Nationally, filing fees range from $40 (Kentucky) to $500 (Massachusetts) and annual fees range from $0 (several states) to $800+ (California) — so South Dakota's cost may be far cheaper, or more expensive, than forming elsewhere. Don't form in Delaware or Wyoming just for their reputation — you'll still need to register as a foreign LLC at home and pay both states.
What Affects Your Results
State Filing Fee
One-time formation costs range from $40 (Kentucky) to $500 (Massachusetts). This is a one-time cost but varies 10x+ between states.
Annual Report/Franchise Tax
The ongoing annual cost varies from $0 (several states) to $800+ (California). South Dakota's annual requirement — missing the deadline can lead to administrative dissolution.
Registered Agent
Every LLC needs a registered agent in the state of formation. You can serve as your own (free but public record), or use a service ($50-$300/year for privacy and reliability).
Business Licenses
Local business licenses ($25-$500) and industry-specific permits add to the cost. These vary by city/county and business type, not just state. Always check your local requirements.
Tips for South Dakota Residents
- Form in your home state unless you have a specific legal reason not to. Delaware and Wyoming LLCs sound appealing but require foreign LLC registration at home anyway — doubling your filing fees and paperwork.
- Check South Dakota's annual franchise tax before forming. California charges $800/year even if the LLC earns zero revenue. This catches many new business owners off guard.
- You don't need a lawyer to form an LLC (most state websites have simple online filing), but DO get a proper operating agreement — especially for multi-member LLCs. This document prevents disputes.
- Skip LLC formation services that charge $200-$500. Most state filings take 15-30 minutes online. Services like LegalZoom add cost without meaningful value for simple single-member LLCs.
- Get a separate EIN (free from IRS.gov) and business bank account immediately. This maintains the "corporate veil" that protects your personal assets from business liability.
