Yes Where it's filed On the periodic/annual report — no dedicated interim filing Filing / update method Annual Report Filing fee $20 (verify current fee status at biz.mt.gov — fee has been waived in recent years) Processing time Filed per Montana's standard Annual Report schedule; no separate expedited interim option confirmed Expedited Not available Online filing Available Same filing as registered agent change? No — a separate matter ## Does Montana Even Track My LLC's Address? Montana's Annual Report is the primary way to keep your LLC's principal office address current with the Secretary of State, filed separately from your registered agent's information. ## Is This the Same As Changing My Registered Agent? Montana's Statement of Change of Registered Agent ($15) only updates your registered agent — it's a separate filing from the Annual Report used to keep your principal address current. - **Your LLC's principal/mailing address** is where your business is actually run from — it can change any time your business relocates, and it has nothing to do with who receives legal documents on the LLC's behalf. - **Your registered agent's address** is the location where the state and any process server can reach your registered agent — it changes only when you switch registered agents or your agent moves. If you're actually looking to switch registered agents in Montana, see [How to Change Your Registered Agent in Montana](/states/mt/change-registered-agent-montana) instead. ## How to Change Your LLC's Address in Montana 1 ### Confirm Where Your Address Actually Lives on the Public Record On the periodic/annual report — no dedicated interim filing with the Montana Secretary of State. Confirm your current filing status before you file anything new. 2 ### Complete Annual Report Get the current form from the Montana Secretary of State and enter your LLC's name, file/entity number, and new address. This filing is separate from a registered-agent change — file it even if your agent isn't changing. 3 ### File and Pay the Fee Submit online or by mail with the Montana Secretary of State. The fee is $20 (verify current fee status at biz.mt.gov — fee has been waived in recent years). Processing takes Filed per Montana's standard Annual Report schedule; no separate expedited interim option confirmed. 4 ### Follow the Update Timing Rule No independently confirmed on-demand address-only filing exists for Montana beyond the Annual Report itself — update your address the next time you file it, or contact the Montana Secretary of State directly if you need it corrected sooner. 5 ### Update Everything Else Once the state's record (if any) reflects your new address, update your operating agreement, IRS records, bank accounts, licenses, contracts, and website. See the full checklist below. Montana's standalone interim principal-office-address filing (separate from the Annual Report) was not independently confirmed in this research pass — this entry assumes the Annual Report is the primary update path, consistent with the state's already-verified compliance data. Montana's Annual Report fee itself has fluctuated (waived in some recent years) — verify the current fee at biz.mt.gov before publishing, and confirm with the Secretary of State whether a dedicated address-change form exists. ## What to Update After Changing Your LLC's Address - **Operating agreement** — update the address if it's listed in the document - **IRS / EIN** — file Form 8822-B to update your business address with the IRS; this is required within 60 days of the move regardless of what your state requires - **Business bank accounts** — most banks require written notice or an updated signature card - **Business licenses and permits** — some are tied to a specific location and may need to be reissued or transferred - **Contracts and agreements** — update your address in any active contracts, leases, and vendor agreements - **Mail forwarding** — set up USPS mail forwarding from your old address during the transition - **Website and marketing materials** — business listings, letterhead, invoices, and online directories **LLC Attorney clients:** Address changes are free within the first 90 days of formation.
