What you pay, and when
| To form it | $35.00, once. $35 is the whole thing for an ordinary LLC. A series LLC pays $50 more for each series named. |
| Every year after | Free. Due April 15 every year, and the fee is waived if you file on time — the Secretary of State has waived it for 2024, 2025 and 2026 and has announced 2027 as well. File after April 15 and it is $35. The waiver is a decision that gets made each year rather than a law, so it is worth checking the fee page before you assume it is free again. |
| If you miss it | $35 for a report filed after April 15 rather than the waived fee. Stop filing altogether and reinstating costs $35, plus another $35 for every year of reports you did not file. |
| Registered agent | Required. You can be your own if you have a street address in Montana and do not mind it being public. |
Do it yourself
You file this directly with the state. There is nobody in the middle who has to be paid to do it, and nothing on this page is a Base888 charge — the fees above are paid to Montana.
