Montana charges $35 to form an LLC; Tennessee 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, Montana runs about $1,465 less in total state fees than Tennessee. Whether that gap matters depends on whether you actually operate in one of these states or are weighing a non-resident filing.

Tennessee imposes an entity-level annual tax on every LLC ($100 minimum). Montana does not. For pass-through LLCs that would otherwise owe nothing at the state level, that minimum is the deciding line.

On speed, Tennessee typically clears standard online filings faster than Montana. 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.

Key differences at a glance

  • Montana costs $265 less to form ($35 vs $300).
  • Montana is $400 per year cheaper to maintain ($100 vs $500).
  • Tennessee has no state individual income tax; pass-through LLC income flows to members without a state layer. The other state does tax at the member level.
  • Tennessee imposes an entity-level franchise or LLC tax that applies to pass-through LLCs. Montana does not.

Where each state fits

For most filers, forming in the state you actually operate from is the right call. The side-by-side below shows where the two states meaningfully diverge.

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.

Montana

  1. Check business-name availability on the Montana entity search.
  2. Appoint a registered agent with a physical Montana street address.
  3. File Articles of Organization for Domestic Limited Liability Company for $35.
  4. Wait for approval. Online typically 5 business days. Paid expedite from $20.
  5. Adopt an operating agreement (recommended, not required by Montana 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.

Tennessee

  1. Check business-name availability on the Tennessee entity search.
  2. Appoint a registered agent with a physical Tennessee street address.
  3. File Articles of Organization – Limited Liability Company (Form SS-4270) for $300.
  4. Wait for approval. Online typically 1 business days. No paid expedite offered.
  5. Adopt an operating agreement (recommended, not required by Tennessee 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 $300 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 Montana and Tennessee (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 Montana or Tennessee 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 Montana or Tennessee?

    Montana is cheaper at formation ($35) than Tennessee ($300). Ongoing costs are also different: $100 vs $500 per year. Total over three years: $335 vs $1,800.

  • Can I form an LLC in Montana if I live in Tennessee?

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

    Montana online: 5 business days; Tennessee online: 1 business day. Montana offers paid expedite from $20. Tennessee does not offer paid expedite.

  • Which state has lower taxes for an LLC, Montana or Tennessee?

    Montana: state income tax applies to member-level pass-through income, no entity-level franchise or LLC tax. Tennessee: no state income tax, plus a $100 minimum entity-level 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. Montana and Tennessee 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 Montana or Tennessee 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.
