How to Start an LLC in Montana (2026): Step-by-Step Guide

Published: June 2026 · Updated for the 2026 tax year

Montana is the state people pick when they want an LLC that's cheap to start, cheap to keep, and sits in a state with no sales tax. All of that is true — the $35 filing fee is one of the lowest in the country, and the $20 annual report (currently waived if you file on time) makes it about as inexpensive as state-level compliance gets. It's also the state at the center of the famous "register your car through a Montana LLC and skip the sales tax" strategy, which is the real reason a lot of people search for this. This guide walks through every step, what a Montana LLC actually costs year by year, the honest truth about the vehicle question, how to form one from outside the US, and your first 90 days.

A note from Slava

I'm Slava, co-founder and CEO of Jupid. Before this I co-founded and scaled an AI-powered accounting platform to around $30M in revenue and more than 100,000 business users — which means I've watched a lot of founders set up in low-tax states for the right reasons, and a few set up in Montana for a reason that gets them in trouble.

Montana is genuinely a great, cheap state to form an LLC: no sales tax, no franchise tax, $35 to file, $20 a year. If you live and operate in Montana, this is an easy yes. The trouble comes from the other thing Montana is famous for — using a Montana LLC to register an expensive car or RV and dodge your home state's sales tax. It's a real strategy, openly sold by an entire cottage industry of registered agents, and it works exactly until your home state notices that the vehicle lives in your driveway, not in Montana. Then it isn't tax planning anymore; it's a use-tax assessment with penalties and interest stacked on top, and it can cost more than you saved.

So this guide does two things most "how to start an LLC in Montana" articles won't: it gives you the real numbers, and it gives the vehicle question a straight, dedicated answer instead of either selling you the loophole or pretending you didn't ask. Everything here is current for 2026, with links to the official sources so you can verify before you file.

Should you actually form your LLC in Montana?

If you live in Montana and run your business from Montana, forming your LLC in Montana is the obvious call — and a genuinely cheap one. There's no sales tax, no franchise tax, a $35 filing fee, and a $20 annual report that's currently free if you file on time. Hard to beat.

The harder question is whether to form in Montana when you don't live there. People are drawn to it for two different reasons, and they deserve different answers. If you're location-independent — an online business with no physical footprint, a holding company, a non-US founder with no US presence — Montana is a reasonable, inexpensive choice, in the same family as Wyoming. But if you have a physical presence somewhere else — an office, employees, inventory, a storefront — a Montana LLC doesn't save you anything: you'd have to register it as a foreign LLC in the state where you actually operate, pay that state's fees, keep a registered agent in both states, and end up paying more for more paperwork. Forming in Montana and operating elsewhere is the classic mistake. If that's you, form where you operate.

And if the reason you're here is the vehicle strategy — registering a car or RV through a Montana LLC to skip sales tax — read that section below before you do anything. It's not the slam dunk the formation mills make it sound like.

For everyone with real Montana roots: Montana it is. Here's how.

How to start an LLC in Montana, step by step

1. Choose and check your LLC name

Your name has to include "Limited Liability Company," "LLC," "L.L.C.," "Limited Company," "LC," or "L.C." ("Limited" can be shortened to "Ltd." and "Company" to "Co."), and it has to be distinguishable from every other entity on the Secretary of State's records. Search the Montana business database before you get attached to anything. Need ideas or want to check a few options at once? Our Montana business name generator is built for exactly that. If you want to lock a name in before you file, a name reservation holds it for 120 days for $10 — though most filers skip this and just file.

2. Appoint a Montana registered agent

Every Montana LLC needs a registered agent who can accept legal papers and official notices on its behalf. That's either an individual who actually lives in Montana with a physical street address — a P.O. box won't do — or a commercial registered agent authorized in Montana. You can serve as your own agent if you have a qualifying Montana address; the LLC itself cannot. The agent's name and address become public record on the SOS database, which is one reason out-of-state owners (and Montana residents who'd rather not list a home address) hire a commercial registered agent for roughly $50–$150 a year.

3. File the Articles of Organization

This is the step that creates your LLC. File online through the biz.sosmt.gov portal for $35 — one of the lowest formation fees of any state. You'll list the LLC name, the registered agent and Montana address, the management structure (member-managed or manager-managed), and the business address. Standard processing takes about 5–7 business days at no extra charge; if you're in a hurry, 24-hour priority handling is $20 and 1-hour expedite is $100. Once it's approved, download the stamped copy — your bank will ask for it.

4. Write an operating agreement

Montana doesn't legally require an operating agreement, but you should have one. Your bank will ask for it, and it's part of how you keep personal and business liability separate. It sets out ownership percentages, how profits are split, who can make decisions, and what happens if a member leaves. Even a single-member LLC should have one. You don't file it with anyone — keep it with your company records.

5. Get your EIN from the IRS

An EIN is your LLC's federal tax ID, and you need it to open a bank account, hire anyone, and file taxes. It's free. Apply at irs.gov — if you have an SSN or ITIN, the online application takes a few minutes. If you don't (common for non-resident owners), file Form SS-4 by fax, mail, or the IRS international phone line; see the non-resident section below. Never pay a third party for the EIN itself — the number is always free from the IRS.

6. Open a US business bank account and set up bookkeeping

Bring the EIN confirmation letter, the filed Articles, the operating agreement, and your ID. Traditional US banks usually want the owner present; several fintech business-banking platforms onboard out-of-state and foreign-owned US LLCs remotely (policies change — check current terms). At the same time, set up bookkeeping — especially if you're a foreign owner, because you'll need a clean record of every dollar moving between you and the LLC for the Form 5472 filing covered below.

7. Calendar your annual report

Every year, file the Montana Annual Report through the SOS portal between January 1 and April 15. The standard fee is $20 — and right now the on-time fee is waived for 2026 and 2027 under a fee-relief program, so on-time filers pay $0 in those years. File after April 15 and the fee jumps to $35 (a $15 late penalty), and continued failure to file gets your LLC administratively dissolved. Put April 15 on the calendar regardless.

What a Montana LLC really costs, year by year

Most guides quote a filing fee and stop — and a lot of them quote the wrong one. (You'll see "$70" in places; that's actually Montana's fee for a Domestic Business Trust or a foreign LLC's Certificate of Authority, not a domestic LLC. The real Articles of Organization fee is $35.) Here's the fuller, correct picture.

Year one

Every following year

That's about as cheap as state-level LLC compliance gets — cheaper than Wyoming's $60-a-year annual report, and a world away from California's $800 minimum franchise tax. The catch is the same one that applies to any low-fee state: the cheap Montana fees only stay cheap if Montana is genuinely where your business lives. Operate in another state and you'll add that state's foreign-registration fees and a second registered agent, and the math changes.

One thing Montana has that Wyoming and Nevada don't: a state income tax. It's modest — a two-rate 4.7% / 5.9% structure — and it only applies to Montana-taxable income, but it's real, and it's why "Montana = no taxes" is wrong. Montana has no sales tax and no franchise tax. It does tax income.

DIY versus a formation service versus Jupid. Filing through the state portal is genuinely easy and cheap. A formation service charges $0–$300 on top of the $35 (the "$0" packages still pass through the state fee and then upsell you a registered agent and a "compliance" subscription). Jupid forms your Montana LLC for free — you pay only the $35 state fee — and then handles the bookkeeping and tax filings afterward, which is where most of the ongoing cost and hassle actually lives.

The "Montana LLC" vehicle question — honestly

This is the search that brings most people to Montana, so let's answer it straight, neither selling it nor dodging it.

How it works. Montana has no general sales tax. So if you title an expensive vehicle — a luxury car, a motorhome or RV, an exotic, an aircraft, a collector car — to a Montana LLC, you can register it in Montana and avoid the sales or use tax your home state would charge on the purchase. On a six-figure vehicle that's often $7,000–$10,000 or more. A Montana registered agent forms the LLC and handles the registration paperwork for a fee, and the LLC (not you personally) owns the vehicle. There's an entire industry built around doing exactly this.

Why it's tempting. The tax savings are large and immediate, the LLC is cheap to form, and Montana's vehicle registration costs are themselves low. On paper it looks clean: a Montana entity owns a vehicle registered in Montana.

Why it's risky — and where it falls apart. Almost every state has a use tax that mirrors its sales tax. If the vehicle is primarily used, stored, or garaged in your home state, that state generally still has the right to tax it — the Montana plate doesn't change where the car actually lives. And states treat an LLC formed solely to avoid sales tax as a sham: they look through it and assess the tax against you, the individual, personally. The bill isn't just the tax you skipped — it's the tax plus registration fees, penalties (which can reach 100% of the tax due), and interest, which routinely adds up to more than the original savings. In cases with clear intent to defraud, it can cross from a civil assessment into criminal tax evasion.

This isn't theoretical. States now use automated license-plate readers, toll and GPS data, insurance-database matching, and dedicated legislation to find Montana-plated vehicles that live elsewhere. Tax authorities in states including California, Colorado, Georgia, Illinois, Indiana, Missouri, Texas, Utah, and Florida have been notably aggressive about pursuing it.

When it's legitimate vs. when it's evasion. The line is about where the vehicle (and you) actually are, not about whether the LLC technically exists:

• Legitimate: the Montana connection is real — you live in Montana, or the vehicle is genuinely based, used, and garaged in Montana, or it belongs to a business with real Montana operations. Then Montana registration is just where your stuff actually is.
• Evasion: you're a resident of another state forming a Montana LLC purely to put a Montana plate on a car that lives in your own driveway, in your own state, where you drive it every day. That's the version states pursue, and they win.

The honest one-liner: a Montana LLC changes where the paperwork is; it doesn't change where you and the vehicle actually live — and your home state taxes you based on where you live and use it. If you have a real Montana nexus, great. If you don't, the expected value of this strategy is negative once you weight in the penalties and the odds of getting caught. Talk to a tax professional in your state before you rely on it.

Forming a Montana LLC as a non-resident or foreign founder

You can own a Montana LLC without being a US citizen or resident — Montana imposes no residency requirement on members or managers. The practical hurdles are a Montana agent, an EIN, a US bank account, and your federal tax filings.

Registered agent. If no member lives in Montana with a real street address, you must use a commercial registered agent here. Budget around $50–$150 a year. P.O. boxes and mailbox-store addresses don't qualify. Line this up before you file, because the agent is named in the Articles.

Getting an EIN without an SSN. The IRS online EIN tool requires the responsible party to have an SSN or ITIN, so foreign founders generally can't use it. Instead, file Form SS-4: where it asks for the responsible party's SSN/ITIN/EIN, write "Foreign" — don't invent a number. Submit it by fax or mail, or call the IRS international EIN line (it's not toll-free), where someone outside the US can get the number over the phone. Check the current Form SS-4 instructions for the right fax and phone numbers, since the IRS changes them. Fax turnaround is usually about four business days; phone is immediate. The EIN is free.

ITIN. An ITIN (Form W-7) is a tax ID for individuals who aren't eligible for an SSN. Your LLC gets an EIN; you as an owner may separately need an ITIN if you have to file a personal US return — for instance, if the LLC is engaged in a US trade or business and you file a Form 1040-NR. It's separate from the LLC's EIN and can take a couple of months.

The Form 5472 obligation — don't skip this. A single-member LLC owned by a non-US person is a "disregarded entity" that generally must file Form 5472 along with a pro-forma Form 1120 every year, even with zero income, reporting transactions between the LLC and its foreign owner — including the capital you put in. The penalty for failing to file (or filing late or substantially incomplete) is $25,000, and it can't be e-filed by a disregarded entity (paper or fax only). A US-owned single-member LLC files a Schedule C instead, and a multi-member LLC files Form 1065 — so this specific filing is a foreign-single-member thing. Almost no Montana LLC guide mentions it; build it into your annual calendar from day one.

US bank account. Most US banks want the owner physically present to open a business account, along with the EIN confirmation letter, the filed Articles, the operating agreement, and a passport. Several fintech business-banking platforms onboard non-resident-owned US LLCs remotely — eligibility and policies change, so check current terms.

Montana tax. Unlike Wyoming or Nevada, Montana does have an income tax — but it only reaches Montana-source income. A non-resident running a purely online Montana LLC with no Montana activity generally has no Montana income-tax return to file, though the LLC still owes the $20 annual report and must keep its Montana registered agent. Your federal obligations (effectively-connected-income rules, possible withholding, and the Form 5472 filing above) are the part to plan around, along with any tax in a state where you actually operate.

Registered agents and the Corporate Transparency Act (BOI)

Your Montana registered agent is the person or company designated to receive lawsuits and official notices for the LLC. It has to be a Montana resident with a physical street address or a commercial registered agent — and because the agent's name and address are public on the SOS database, plenty of Montana residents hire a commercial agent purely to keep their home address off the record.

On the federal beneficial-ownership side: under the Corporate Transparency Act, LLCs were originally required to file a Beneficial Ownership Information (BOI) report with FinCEN. That changed. FinCEN's interim final rule, published in March 2025, redefined a "reporting company" to mean only entities formed under foreign law that register to do business in a US state. As of early 2026, that means a Montana-formed LLC — even one with foreign owners — has no BOI filing obligation. FinCEN has said it intends to finalize the rule during 2026, so this could shift; check fincen.gov/boi before you assume one way or the other. (If you register a foreign-formed entity to do business in Montana, the foreign-entity BOI rules still apply to that entity, though it need not report US-person owners.)

Your first 30, 60, and 90 days

Days 1–7

• Get your EIN from the IRS (free; online if you have an SSN/ITIN, otherwise by fax, mail, or phone).
• Adopt a written operating agreement — kept with your records.
• Check your BOI status. As of early 2026 a domestic Montana LLC has nothing to file with FinCEN; re-verify at fincen.gov/boi.

Days 1–30

• Open a US business bank account (EIN letter, filed Articles, operating agreement, ID).
• Confirm your registered agent's appointment is on file.
• Get any professional or industry licenses your work requires — Montana has no statewide general business license, but cities and certain trades do.
• Look into business insurance — general liability now, workers' comp once you have employees.

Days 31–60

• Set up bookkeeping. If you're a foreign owner, set it up specifically to track money moving between you and the LLC for the annual Form 5472 + pro-forma 1120 filing.
• If you'll have Montana employees or Montana-source income, register with the Montana Department of Revenue and set up federal payroll.
• If you operate in another state, register the Montana LLC there as a foreign LLC before you're "doing business" there.

Days 61–90

• Calendar the Montana Annual Report — due between January 1 and April 15 every year. Set a reminder about 45 days out.
• Decide on tax treatment for the year (default pass-through, or an S-corp election once profits justify it).

By April 15 every year — hard deadline

• File the Montana Annual Report ($20, currently waived on time for 2026 and 2027; $35 if late). Miss it long enough and the LLC is administratively dissolved.

Common mistakes with Montana LLCs

Using a Montana LLC to register a car that lives in another state. Why it hurts: your home state can assess use tax, registration fees, penalties of up to 100% of the tax, and interest — often more than the sales tax you avoided — and treat the LLC as a sham. Fix: only register a vehicle to a Montana LLC if it genuinely lives, and is used, in Montana; otherwise pay your home state's tax.

Forming in Montana but operating in another state. Why it hurts: you owe foreign-registration fees and a second registered agent in the state where you actually do business — usually more than the Montana fees you "saved." Fix: if you have a real physical presence somewhere, form there; reserve Montana for genuinely Montana-based or location-independent businesses.

Assuming "no sales tax" means "no taxes." Why it hurts: Montana has a state income tax (4.7% / 5.9%), so a profitable LLC owes Montana income tax on Montana-taxable income even though there's no sales or franchise tax. Fix: budget for income tax on profits and consider the elective pass-through entity tax if it helps with the federal SALT cap.

Missing the April 15 annual report. Why it hurts: the fee climbs from $20 (currently waived on time) to $35, and chronic non-filing gets the LLC administratively dissolved — which freezes your ability to do business and forces a paid reinstatement. Fix: calendar April 15 with a 45-day warning and file early.

Ignoring Form 5472 as a foreign owner. Why it hurts: a $25,000 penalty for a filing many non-resident owners have never heard of. Fix: set up the pro-forma 1120 + 5472 process in year one and keep records of every transfer between you and the LLC.

Frequently asked questions

How much does it cost to start an LLC in Montana in 2026? The state filing fee for the Articles of Organization is $35 — one of the lowest in the country. The annual report is $20 a year (and the on-time fee is currently waived for 2026 and 2027). There's no franchise tax and no sales tax, so a typical first-year cost is about $35–$55 before any registered agent service.

Can I use a Montana LLC to buy a car without sales tax? You can register a vehicle to a Montana LLC, and Montana has no sales tax — that's the basis of the well-known strategy. But it only holds up if the vehicle genuinely lives in Montana. If you garage and drive it in another state, your home state can assess use tax, registration fees, penalties, and interest, often totaling more than you "saved," because it treats an LLC formed purely to dodge sales tax as a sham. Several states pursue this aggressively. Don't use a Montana LLC to register a car that actually lives somewhere else.

Do I need a registered agent for a Montana LLC? Yes. It can be you or another Montana resident with a physical street address, or a commercial registered agent. The LLC cannot be its own agent, and P.O. boxes aren't allowed. The agent's name and address are public on the Secretary of State's database.

Does Montana have a state income tax? Yes. Unlike Wyoming or Nevada, Montana has a state income tax — a two-rate structure of 4.7% and 5.9% as of 2024. LLC profits pass through to the owners and are taxed at those personal rates. What Montana doesn't have is a sales tax or a franchise tax.

Can a non-US resident own a Montana LLC? Yes. Montana has no citizenship or residency requirement for members. You'll need a commercial registered agent in Montana and an EIN (which you can get without an SSN). A foreign-owned single-member LLC must also file Form 5472 with a pro-forma Form 1120 every year — the penalty for missing it is $25,000.

Does Montana require LLCs to publish a formation notice in a newspaper? No. Unlike New York, Arizona, Nebraska, Georgia, and Pennsylvania, Montana has no newspaper publication requirement for LLCs.
