Not by itself. A customer's address differs from carrying on business in that state. Where people work, property is held, and a business maintains an office can change the answer.
Start with the activity, not the customer's address
A Texas freelancer working only in Texas for a California client presents different facts from a company whose employees regularly work in California. California's LLC statute excludes some activities from “transacting intrastate business,” including sales through independent contractors, certain orders accepted outside California, and interstate commerce. These are not blanket exemptions for remote businesses. California Corporations Code §17708.03
Check the state where business happens
Texas requires an out-of-state filing entity to register when it transacts business there, but its statute does not fully define that phrase. The Secretary of State cites an office or employee as common indicators and says it cannot decide every case. Florida similarly lists activities that alone do not count, including certain out-of-state-accepted orders and interstate commerce; Florida says owning income-producing real or tangible personal property generally does count under this provision.

Work through the facts
- List where owners and staff actually work and where offices, inventory, equipment, or real estate sit.
- Check where contracts are accepted and whether the state excludes the activity from its foreign-LLC rule.
- Check tax, licenses and permits separately. A registration exemption does not answer those questions.
If the work spans states or the rule is unclear, seek state-specific legal advice before filing or skipping a registration. See the two-state cost decision and Texas guidance.

Frequently asked questions
Does one client in another state require foreign registration?
Not automatically. Compare actual activity and the foreign-LLC law of that state; client address alone is not a sufficient test.
What if my employees work in the client’s state?
That can change the analysis. Texas cites employees or an office as common indicators; other states have their own statutes and exceptions.
Does an online sale count as doing business in another state?
Not always. California and Florida list some interstate transactions and out-of-state-accepted orders as excluded activities, but the conditions matter.
If foreign registration is not required, are taxes and licenses settled?
No. California and Florida distinguish the LLC registration question from tax and other state regulation. Check each separately.
