Kentucky charges $40 to form an LLC; Maine charges $175. 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, Maine runs about $180 less in total state fees than Kentucky. Whether that gap matters depends on whether you actually operate in one of these states or are weighing a non-resident filing.

Kentucky imposes an entity-level annual tax on every LLC ($175 minimum). Maine does not. For pass-through LLCs that would otherwise owe nothing at the state level, that minimum is the deciding line.

On speed, Kentucky typically clears standard online filings faster than Maine. 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.

Kentucky

  1. Check business-name availability on the Kentucky entity search.
  2. Appoint a registered agent with a physical Kentucky street address.
  3. File Articles of Organization for a Profit Limited Liability Company (Form KLC) for $40.
  4. Wait for approval. Online typically 1 business days. No paid expedite offered.
  5. Adopt an operating agreement (recommended, not required by Kentucky 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 $15 when it comes due.

Maine

  1. Check business-name availability on the Maine entity search.
  2. Appoint a registered agent with a physical Maine street address.
  3. File Certificate of Formation (Form MLLC-6) for $175.
  4. Wait for approval. Paper-only processing. Paid expedite from $50.
  5. Adopt a written operating agreement (statutorily required in Maine).
  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 $85 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 Kentucky and Maine (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 Kentucky or Maine 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 Kentucky or Maine?

    Kentucky is cheaper at formation ($40) than Maine ($175). Ongoing costs are also different: $290 vs $185 per year. Total over three years: $910 vs $730.

  • Can I form an LLC in Kentucky if I live in Maine?

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

    Kentucky online: 1 business day; Maine online turnaround varies. Kentucky does not offer paid expedite. Maine offers paid expedite from $50.

  • Which state has lower taxes for an LLC, Kentucky or Maine?

    Kentucky: state income tax applies to member-level pass-through income, plus a $175 minimum entity-level tax. Maine: 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. Kentucky and Maine 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 Kentucky or Maine?

    Maine requires LLCs to adopt a written operating agreement by statute. Kentucky 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 Kentucky or Maine 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.
