The fee, the form, what triggers registration in California, and how to file.
The Secretary of State posts the receipt date it is currently working on: as of its 21 August 2026 update, LLC formations and registrations stood at 20 August for online filings and 17 August for post. Check that page rather than relying on a stored figure, because it moves.
Class A four hour service is $500 but is drop-off only in Sacramento and requires the document to have been precleared first at a further $500, so it is $1,000 and a trip to Sacramento rather than a faster checkbox.
Northwest files the foreign registration and serves as your registered agent in California, which the filing requires. Only need an agent? Northwest's registered agent service alone is $125/year.

California carves 10 activities out by statute. On their own, none of them requires a foreign LLC to register.
Under Corporations Code Section 17708.03(b), 10 items. California's isolated-transaction window is 180 days, not the usual 30. California has NO standalone safe harbor for simply owning real or personal property. Subsection (c) adds six status-based exclusions (shareholder, limited partner, member or manager of another entity) and subsection (e) states the section does not determine service of process, taxation, or regulation under other California law. Note that Corporations Code Section 191 governs foreign CORPORATIONS and does not reach LLCs, so a citation to it for this list is wrong.
