South Dakota charges $150 to form an LLC; Texas charges $300. Day-one sticker price is only part of the story, since most of the real cost comes from the annual obligations that stack up each year you keep the LLC open.

Over a rolling three-year window, Texas runs about $15 less in total state fees than South Dakota. Whether that gap matters depends on whether you actually operate in one of these states or are weighing a non-resident filing.

On speed, South Dakota typically clears standard online filings faster than Texas. Both states offer expedited tiers at an additional cost for filers on tight timelines.

For most small operators the choice is not really between these two states at all. It is between forming where the business actually operates and trying to route through a non-resident filing. The data below shows what each option actually costs.

Formation process, side by side

What actually happens from the moment you start filing to the moment you're in good standing. Use this as a checklist.

South Dakota

  1. Check business-name availability on the South Dakota entity search.
  2. Appoint a registered agent with a physical South Dakota street address.
  3. File Articles of Organization (Domestic Limited Liability Company) for $150.
  4. Wait for approval. Online typically 1 business days. Paid expedite from $50.
  5. Adopt an operating agreement (recommended, not required by South Dakota statute).
  6. Apply for a federal EIN (free from the IRS).
  7. Open a business bank account to separate personal and business finances.
  8. File your first annual report and pay $55 when it comes due.

Texas

  1. Check business-name availability on the Texas entity search.
  2. Appoint a registered agent with a physical Texas street address.
  3. File Certificate of Formation: Limited Liability Company (Form 205) for $300.
  4. Wait for approval. Online typically 13 business days. Paid expedite from $25.
  5. Adopt an operating agreement (recommended, not required by Texas statute).
  6. Apply for a federal EIN (free from the IRS).
  7. Open a business bank account to separate personal and business finances.
  8. File your first annual report and pay $0 when it comes due.

Before you pick either state

A few things that apply no matter which state you choose. These trip up enough first-time filers that they're worth stating explicitly.

Registered agent is non-negotiable. Both South Dakota and Texas (and every other US state) require every LLC to designate a registered agent with a physical street address in the state of formation. You can serve as your own agent if you live in the state; otherwise a commercial agent runs $50 to $125 per year. Using your own home address makes it part of the public record.

Forming elsewhere does not escape your home state's tax. If you live and operate a business from your home state, forming the LLC in South Dakota or Texas does not avoid your home state's income tax. The moment you transact business at home, your home state requires a foreign LLC registration, and state tax liability follows your residence regardless of where the entity sits on paper.

EIN applications are free. The IRS issues Employer Identification Numbers directly at no cost. Any service charging you to "get your EIN" is reselling a free form submission. Single-member LLCs with no employees technically don't need one for federal tax, but nearly every bank requires an EIN to open a business account.

Operating agreement matters more than the state you pick. A well-drafted operating agreement governs member ownership, management, profit splits, buy-sell terms, and dissolution. Without one, your LLC runs on the state's default rules, which are rarely what you want. California, Maine, Missouri, and New York require a written one by statute; every other state treats it as strongly recommended.

Frequently Asked Questions

  • Is it cheaper to form an LLC in South Dakota or Texas?

    South Dakota is cheaper at formation ($150) than Texas ($300). Ongoing costs are also different: $155 vs $100 per year. Total over three years: $615 vs $600.

  • Can I form an LLC in South Dakota if I live in Texas?

    Yes, but your Texas business will almost certainly need to register as a foreign LLC in Texas too, which means paying Texas's foreign registration fee and any ongoing Texas obligations on top of the South Dakota ones. The "form elsewhere to save" math usually doesn't work for operating businesses; it only works when you have no physical operations tied to any specific state.

  • How long does it take to form an LLC in South Dakota vs Texas?

    South Dakota online: 1 business day; Texas online: 13 business days. South Dakota offers paid expedite from $50. Texas offers paid expedite from $25.

  • Which state has lower taxes for an LLC, South Dakota or Texas?

    South Dakota: no state income tax, no entity-level franchise or LLC tax. Texas: no state income tax, no entity-level franchise or LLC tax.

  • Do both states require a registered agent?

    Yes. Every US state (and DC) requires every LLC to maintain a registered agent with a physical street address in the state. South Dakota and Texas both have this requirement. You can serve as your own agent if you live in the state; most out-of-state filers use a commercial agent for $50 to $125 per year.

  • Which state should I pick if I run an online business from home?

    Form in the state you actually live in. Your home state's Department of Revenue treats your residence as nexus regardless of where the LLC is filed, which means you owe state income tax there anyway. Forming in South Dakota or Texas to escape your home state's tax doesn't work; it adds paperwork. The non-resident filings make sense when you genuinely operate nowhere in particular: international founders, purely passive holding entities, or real-estate LLCs owning property in other states.
