How Long Does It Take to Form an LLC in Montana (2026)
Montana's Secretary of State typically approves a standard online LLC filing in about 5 to 6 business days. Faster options exist too: $20 buys 24-hour turnaround, and $100 buys 1-hour approval if you need it the same day. The state filing fee is $35. Every filing goes through Montana's online Business Filing Portal, since the state doesn't accept paper filings by mail.
That timeline assumes a complete application. Montana requires every LLC to name a registered agent who lists a Montana address, and the filing can't be approved without one. The online form flags any missing field before you can submit it. It won't catch a wrong address or a typo, though, and neither one gets approved as filed.
The Business Filing Portal handles a heavy, steady volume of new business filings year-round. Processing speed can shift slightly with demand. The rest of this guide breaks down what each processing option costs and what commonly slows a filing down. It also covers what changed about the state's annual report fee this year.
Quick Summary
- Montana only accepts LLC filings online, through the state's Business Filing Portal. There's no mail-in option.
- Paying for expedited processing doesn't fix a filing with missing or incorrect information. The state still bounces those back.
- The state is currently waiving its annual report fee, but the April 15 filing deadline for the report itself still applies.
What Is the Fastest Way to Form an LLC in Montana
| Filing method | Fee | Processing time | Expedited option |
|---|---|---|---|
| Online (standard) | $35 | Typically 5-6 business days | Yes, add $20 or $100 |

The fastest way to form a Montana LLC is filing online and paying for 1-hour expedited processing. The Montana Secretary of State's Business Services Division reviews the paperwork itself. Approval often lands within the hour once it clears.
Montana registered nearly 64,000 new businesses in 2024. New registrations had already passed that total by 2025 [1]. That volume moves through the portal every business day. The queue behind a standard filing can shift depending on exactly when you submit it.
Have your registered agent's mailing address in Montana ready, along with every required field, before you start. An incomplete submission won't clear review, no matter how much you paid for speed.
1. Expedited Online Filing (1-Hour, $100, or 24-Hour, $20)
Montana's Business Services Division sells two speed upgrades. Both sit on top of the $35 base filing fee [2]. Priority handling costs $20 and turns your filing around in 24 hours. The 1-hour tier costs $100 and jumps the standard queue entirely.
Pick 1-hour if you can't wait even a day. Both tiers run through the same Business Filing Portal as a standard filing. You just select the faster tier. Then pay the added cost by card or online check when you submit.
2. Standard Online Filing (5-6 Business Days, $35)
Skip the speed upgrade and you get standard processing, typically about 5 to 6 business days. Create a portal account, complete the Articles of Organization, and submit it with the $35 fee.
Montana has no mail-in option. Paper Articles of Organization aren't accepted by post. The online portal is the only channel the state runs, expedited or not.
What Can Delay Your Montana LLC Filing
A few things commonly add days to a Montana LLC filing, expedited or not. These are the ones that trip filers up most often.
- Missing or wrong registered agent information: The online form blocks submission over an empty required field. It won't catch a registered agent's mailing address that's simply wrong.
- Portal downtime or a payment error: Mail isn't an option, so a stalled online submission has no fallback route until the issue clears.
- Weekends and holidays: The Business Services Division doesn't process filings on non-business days. Anything submitted Friday afternoon waits until Monday.
Montana's Annual Report and Its Current Fee Waiver
Every active Montana LLC files an annual report by April 15 to stay in good standing. Filing on time normally costs $20, and filing late costs $35. Right now, though, the Secretary of State is waiving that fee for the third year in a row [3].
The waiver runs through 2026, and the office has already announced it'll continue in 2027 too. The April 15 deadline still applies even with nothing to pay. The state hasn't called the waiver permanent.
The steps to start the filing itself are covered in our guide on how to start an LLC in Montana. For timelines in every other state, see our guide on how long it takes to form an LLC.
