Is it cheaper to form an LLC in Alaska or Illinois?

Illinois is cheaper at formation ($150) than Alaska ($250). Ongoing costs are also different: $175 vs $150 per year. Total over three years: $675 vs $700.

Can I form an LLC in Alaska if I live in Illinois?

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

Alaska online: 1 business day; Illinois online: 10 business days. Alaska does not offer paid expedite. Illinois offers paid expedite from $100.

Which state has lower taxes for an LLC, Alaska or Illinois?

Alaska: no state income tax, no entity-level franchise or LLC tax. Illinois: state income tax applies to member-level pass-through income, 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. Alaska and Illinois 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 Alaska or Illinois 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.

Alaska vs Illinois LLC comparison

Alaska charges $250 to form an LLC; Illinois 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, Illinois runs about $25 less in total state fees than Alaska. Whether that gap matters depends on whether you actually operate in one of these states or are weighing a non-resident filing.

On speed, Alaska typically clears standard online filings faster than Illinois. 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.

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.

Alaska

Check business-name availability on the Alaska entity search.
Appoint a registered agent with a physical Alaska street address.
File Articles of Organization (form 08-484) for $250.
Wait for approval. Online typically 1 business days. No paid expedite offered.
Adopt an operating agreement (recommended, not required by Alaska 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 $100 when it comes due.

Illinois

Check business-name availability on the Illinois entity search.
Appoint a registered agent with a physical Illinois street address.
File Form LLC-5.5 - Articles of Organization for $150.
Wait for approval. Online typically 10 business days. Paid expedite from $100.
Adopt an operating agreement (recommended, not required by Illinois 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 $75 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 Alaska and Illinois (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 Alaska or Illinois 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.
