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

California is cheaper at formation ($70) than South Dakota ($150). Ongoing costs are also different: $910 vs $155 per year. Total over three years: $2,800 vs $615.

Can I form an LLC in California if I live in South Dakota?

Yes, but your South Dakota business will almost certainly need to register as a foreign LLC in South Dakota too, which means paying South Dakota's foreign registration fee and any ongoing South Dakota obligations on top of the California 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 California vs South Dakota?

California online: 8 business days; South Dakota online: 1 business day. California offers paid expedite from $350. South Dakota offers paid expedite from $50.

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

California: state income tax applies to member-level pass-through income, plus a $800 minimum entity-level tax. South Dakota: 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. California and South Dakota 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.

Do I need a written operating agreement in California or South Dakota?

California requires LLCs to adopt a written operating agreement by statute. South Dakota treats it as strongly recommended rather than required. In practice, any LLC with more than one member, or any LLC planning to preserve its liability shield, should have a written agreement regardless of which state it's formed in.

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 California or South Dakota 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.

California vs South Dakota LLC comparison

California charges $70 to form an LLC; South Dakota charges $150. 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, South Dakota runs about $2,185 less in total state fees than California. Whether that gap matters depends on whether you actually operate in one of these states or are weighing a non-resident filing.

California imposes an entity-level annual tax on every LLC ($800 minimum). South Dakota does not. For pass-through LLCs that would otherwise owe nothing at the state level, that minimum is the deciding line.

On speed, South Dakota typically clears standard online filings faster than California. 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.

What it costs under your specific situation

The table below runs the same LLC through four common scenarios. "Non-resident" rows assume a typical home-state foreign LLC registration adds about $200 per year of stacked cost; the real number depends on which state you live in and ranges from $50 to over $800 depending on jurisdiction.

You live in California, business operates there No foreign LLC registration needed. You pay California fees only.	$980	$910	$2,800
You live in South Dakota, business operates there No foreign LLC registration needed. You pay South Dakota fees only.	$305	$155	$615
Non-resident forming in California with operations elsewhere You pay California's fees plus a typical home-state foreign LLC registration of about $200 per year.	$1,180	$1,110	$3,400

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.

California

Check business-name availability on the California entity search.
Appoint a registered agent with a physical California street address.
File Articles of Organization (Form LLC-1) for $70.
Wait for approval. Online typically 8 business days. Paid expedite from $350.
Adopt a written operating agreement (statutorily required in California).
Apply for a federal EIN (free from the IRS).
Open a business bank account to separate personal and business finances.
File your first annual report and pay $20 when it comes due.

South Dakota

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