Indiana vs Montana LLC: fees, taxes, and which to pick
Data last updated: Apr 21, 2026Indiana charges $95 to form an LLC; Montana charges $35. 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 $108 less in total state fees than Indiana. Whether that gap matters depends on whether you actually operate in one of these states or are weighing a non-resident filing.
On speed, Indiana 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 $60 less to form ($35 vs $95).
- Montana is $16 per year cheaper to maintain ($100 vs $116).

Three-year cost, side by side
Rough estimate of the state-facing cost to form and keep an LLC through three years. Both totals include a $100 per year registered-agent estimate.
Running total includes the one-time filing fee and annual ongoing costs (report fee or franchise tax plus a $100/year registered agent estimate).
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.
| Scenario | Year 1 | Each year after | 3-year total |
|---|---|---|---|
| You live in Indiana, business operates there No foreign LLC registration needed. You pay Indiana fees only. | $211 | $116 | $443 |
| You live in Montana, business operates there No foreign LLC registration needed. You pay Montana fees only. | $135 | $100 | $335 |
| Non-resident forming in Indiana with operations elsewhere You pay Indiana's fees plus a typical home-state foreign LLC registration of about $200 per year. | $411 | $316 | $1,043 |
| Non-resident forming in Montana with operations elsewhere You pay Montana's fees plus a typical home-state foreign LLC registration of about $200 per year. | $335 | $300 | $935 |

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.
Indiana
- Check business-name availability on the Indiana entity search.
- Appoint a registered agent with a physical Indiana street address.
- File Indiana Articles of Organization (State Form 49459) for $95.
- Wait for approval. Online typically 1 business days. No paid expedite offered.
- Adopt an operating agreement (recommended, not required by Indiana 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 $32 when it comes due.
Montana
- Check business-name availability on the Montana entity search.
- Appoint a registered agent with a physical Montana street address.
- File Articles of Organization for Domestic Limited Liability Company for $35.
- Wait for approval. Online typically 5 business days. Paid expedite from $20.
- Adopt an operating agreement (recommended, not required by Montana statute).

- 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 Indiana and Montana (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 Indiana or Montana 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 Indiana or Montana?
Montana is cheaper at formation ($35) than Indiana ($95). Ongoing costs are also different: $100 vs $116 per year. Total over three years: $335 vs $443.
-
Can I form an LLC in Indiana if I live in Montana?
Yes, but your Montana business will almost certainly need to register as a foreign LLC in Montana too, which means paying Montana's foreign registration fee and any ongoing Montana obligations on top of the Indiana 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 Indiana vs Montana?
Indiana online: 1 business day; Montana online: 5 business days. Indiana does not offer paid expedite. Montana offers paid expedite from $20.
-
Which state has lower taxes for an LLC, Indiana or Montana?
Indiana: state income tax applies to member-level pass-through income, no entity-level franchise or LLC tax. Montana: 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. Indiana and Montana 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 Indiana or Montana 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.
