How long does it take to register a business in South Dakota?

Processing times vary: 3-5 business days. Online filings are typically faster than mail submissions. Expedited processing may be available for an additional fee.

Do I need a business license in South Dakota?

South Dakota does not require a state-level business license, but individual cities and counties may have their own requirements. Check with your local government for specific licensing needs.

Can I use my personal name as my business name?

Yes, you can use your personal name as your business name. For an LLC, you'll need to add "LLC" or "Limited Liability Company" to the end. However, using a unique business name often provides better branding opportunities and legal protection.

What if my desired business name is already taken?

If your preferred name is unavailable, you have several options: 1) Choose a different name, 2) Add descriptive words to make it unique, 3) Use a different LLC suffix (LLC, L.L.C., etc.), or 4) Consider filing a "Doing Business As" (DBA) name while keeping a different legal name.

How much does it cost to start a business in South Dakota?

The LLC filing fee is $150. Annual fees are $50. Additional costs include business licenses ($50-500), registered agent fees ($50-300/year if using a service), and other startup expenses. Total first-year costs typically range from $300.

Do I need a trademark for my business name?

While not required, trademark registration provides nationwide protection for your business name. Registering your LLC with the state only protects your name within South Dakota. If you plan to expand beyond the state or want stronger legal protection, consider applying for a federal trademark with the USPTO.

Can I change my business name later?

Yes, you can change your LLC name by filing an amendment with the South Dakota Secretary of State. This typically costs $20-100 and takes a few weeks to process. However, changing your name can be expensive when you consider updating all your marketing materials, domain, signage, and legal documents.
