FAQ

Common questions.

What is the first step to start a business in Montana?

The first real decision is your entity type, because it drives everything after: taxes, liability, and paperwork. For most small businesses in Montana that means forming an LLC, which you do by filing a formation document with the state and naming a registered agent. Get the structure right first, then EIN, banking, and licenses follow in order. We walk you through the Montana sequence so nothing is done out of turn.

Which business structure should I choose in Montana?

Most Montana founders land on an LLC for its liability protection and simple pass-through taxes, but a corporation makes sense if you plan to raise venture capital or issue stock. A sole proprietorship is simplest but leaves your personal assets exposed. The honest answer depends on your goals, so we lay out the LLC-versus-corporation trade-offs for Montana rather than pushing one.

Do I need a registered agent in Montana?

Yes. Montana requires every LLC and corporation to name a registered agent with a physical in-state address to receive legal and state notices. You can be your own, but then your address is public and you must be available during business hours. Most owners use a service to stay private and never miss a notice. We include agent service so this box is checked from day one.

How much does it cost to start an LLC in Montana?

The cost is the Montana state filing fee plus any service you use, and Montana also charges recurring fees such as an annual or biennial report. Our formation service itself is free, and we pass state fees through at cost with no markup. Because state figures change over time, current Montana amounts are on the pricing page rather than quoted here where they could go stale.

Do I need a business license in Montana?

Often yes, and it is usually layered. Montana may require a state-level license for certain activities, and your city or county frequently adds its own, plus industry permits. Very few businesses need nothing at all. We map every Montana license and permit your specific business needs so you open legally instead of guessing which ones apply.

What taxes will my Montana business pay?

It depends on your structure and activity, but expect some mix of federal income and self-employment tax, Montana state taxes where they apply, and sales tax if you sell taxable goods. Some states have no income tax while others add franchise or gross-receipts taxes. Once profits grow, an S-corp election can reduce self-employment tax. We flag which Montana taxes actually apply to you rather than listing every possibility.

Do I need an EIN for my Montana business?

Almost certainly. You need an EIN to open a business bank account, hire employees, or file most business taxes, and it keeps your Social Security number off company paperwork. It is free from the IRS, and our value is getting it right and fast, including for founders without an SSN. We obtain it as part of setting up your Montana entity so banking is not held up.

Can I form my business in another state instead of Montana?

You can, but if you operate in Montana it usually backfires. Forming in Delaware or Wyoming while doing business in Montana means registering in Montana as a foreign entity anyway and paying two states. The out-of-state advantage is real mainly for venture-backed or holding companies. For a business rooted in Montana, forming at home is almost always cheaper and simpler.

What are the ongoing compliance requirements in Montana?

After formation, Montana expects you to keep a registered agent, file the periodic annual or biennial report, pay any state fees, and renew licenses on schedule. Miss these and the state can revoke your good standing or dissolve the entity. We track your Montana deadlines in a compliance calendar and can file the reports for you so nothing lapses while you run the business.
