Forming an LLC in Montana costs $35 to file, then nothing a year to keep in good standing, if you're your own registered agent.
Montana is the cheapest state to keep an LLC in right now, because the state has waived its annual report fee. File the report by April 15 and it costs nothing, though that could change when the waiver ends. Change any choice below, or compare any state in the LLC cost calculator.
Year one counts the filing, set-up items and any tax charged for the year you form. Yearly reports sit under "every year after" even when the first one lands inside your first 12 months; the due dates tab shows exactly when. Taxes that depend on profit or sales are explained, not counted. Not legal or tax advice.

The fee schedule
Assumes you are your own registered agent, file at standard speed and owe no tax based on profit or sales. Figures from Montana's own pages, checked 21 October 2026. Not legal or tax advice.
File it yourself on Montana’s own filing site. You only need a formation service if you want someone else to be your registered agent, or to handle the forms for you. If you’ll run the business from another state, set “Where you’ll run the business” in the calculator: it adds what registering back home costs.
Every service, with its own registered agent price after year one, which is where most of the money is. Cheapest over five years first.

Each service’s own prices, checked 21 Oct 2026. Registered agent in the formation state only. Optional extras are left out, including EIN filing ($50 to $99), which the IRS does free. State fees for Montana are included. Some links are partner links: if you buy, we may earn a commission at no extra cost to you. It never changes the order, which is always cheapest first. How partner links work.
The business tax number is free from the IRS and takes minutes: apply on irs.gov. Services charge $50 to $99 for the same form.
Keep business and personal money apart from day one. That separation is a big part of what the LLC protects.
