How to form an LLC in Montana.

The steps, in order, and what each one asks of you. We can file it in Montana for you, with the registered agent for the first year.

Our staffer hands a client their mail at our front desk, with Montana touches around the office: a fly fishing creel, stacked firewood and a mountain print.

The steps.

  1. Step 1

    Choose a name

    It has to be different from the names already on Montana’s records, and it has to include “LLC” or another ending Montana accepts, such as “Limited Liability Company”.

  2. Step 2

    Name a registered agent in Montana

    Every LLC in Montana needs one: a person or company with a street address in Montana that accepts legal papers for the company during business hours. More on this below.

    The registered agent Montana requires.

  3. Step 3

    File the formation document

    File the formation document with Montana’s business filing office. Its name varies: articles of organization in most states, a certificate of formation or of organization in others. Montana charges a filing fee. It is shown at cost under What it costs in Montana, on this page.

  4. Step 4

    Sign an operating agreement

    It sets out who owns the company and how it is run. It stays with your records and is not filed with the state.

  5. Step 5

    Get an EIN from the IRS

    The EIN is the company’s federal tax number, and banks ask for it. The IRS issues it online, usually at once, when the responsible person has a Social Security number or ITIN and the company’s principal place of business is in the US. Otherwise it is Form SS-4 by fax or mail, which can take 4 to 8 weeks.

  6. Step 6

    Keep up with the ongoing filing

    Montana has a periodic filing for LLCs, and official sources in Montana disagree on when it is due, so confirm the date with the state. Our page on Montana has the details.

The registered agent Montana requires.

An LLC in Montana names its registered agent on the formation document and keeps one for as long as it exists. The agent needs a street address in Montana, not a post office box, and someone there during business hours to sign for legal papers.

You may be able to serve as the agent yourself if you live in Montana or keep an office there, can be reached there during business hours, and do not mind the address on the public record.
