Do I need a registered agent in every state? No. Only where your LLC is registered.

Where the requirement comes from (retrieved 6 October 2026 CT)

The statutes attach the agent duty to the registration, in plain words:

So the question to answer first is not “where are my customers?” It is “which states is my LLC registered in, and which states should it be registered in?”

What usually triggers a foreign registration

Every state defines “transacting business” (or “doing business”) for itself, and mostly by exclusion. The lists in Texas §9.251, California §17708.03, and Washington RCW 23.95.520 overlap a lot. None of these, by itself, counts as doing business there:

• Maintaining a bank account.
• Holding member or manager meetings and other internal affairs.
• Selling through independent contractors.
• Transacting business in interstate commerce. California and Washington also exclude soliciting orders that have to be accepted outside the state.
• A single isolated transaction. Texas and Washington say completed within 30 days; California says 180 days.
• Lawsuits, settlements, and collecting debts.

California states the positive test: a foreign LLC that “enters into repeated and successive transactions of business in this state, other than in interstate or foreign commerce,” is transacting intrastate business. In practice, running an office, shop, or other location in the state, or regularly doing your work there for local clients, is the kind of activity the safe-harbor lists don’t cover. Staff is state by state: Washington’s list says employing a remote worker who lives in Washington does not count by itself; the Texas and California lists don’t mention remote workers.

Skipping registration when you need it has a price. Texas’s fee schedule charges a late fee equal to the $750 registration fee for each year an entity transacted business in Texas for more than 90 days without registering.

Each registration needs its own in-state agent

Your Wyoming agent has a Wyoming street address. That address does nothing for your Texas registration, which needs a Texas agent at a Texas street address, and the same mailbox rules apply as at home (no PO box or virtual mailbox). Commercial agents price it that way: Northwest publishes $125/year, dropping to $100/year per state at five or more states. ZenBusiness’s FAQ says you need an agent with a physical address in each state where the business is registered or qualified.

Can your LLC be its own agent in the new state?

Generally no, unless the new state lets an entity serve and your LLC has a qualifying office there. Texas §5.201(b) allows an organization “other than the filing entity or foreign filing entity to be represented.” California §17701.13(c) allows an individual resident of California or a corporation that has complied with §1505. Your out-of-state LLC isn’t either one.

A person often works, though. The most common multi-state setup is an LLC formed in one state (Wyoming, Delaware) while the owner lives and works in another. The owner, as a resident individual, can usually be the agent in the home state, with the tradeoffs on the be your own registered agent note: your street address on the public record and being reachable there. The formation state still needs a commercial agent unless you live there too.

Sixteen states: foreign LLC filing and state fee

The 3-year bill for agents in more than one state

The agent fee is rarely the biggest number. Three examples, using the fees above:

1. Wyoming LLC run from a home office in Texas. Wyoming formation $100 plus Texas Form 304 $750. Two agents: $750 over three years with Northwest in both states, or $375 if you serve as your own Texas agent. Plus Wyoming’s annual report license tax, at least $60 a year. Forming in Texas instead: $300 and one agent. If the business really lives in Texas, the Wyoming LLC mostly adds a second set of bills.
2. Delaware LLC that operates in California. California LLC-5 $70. Agents in both states: $750 over three years with Northwest. Delaware’s $400 annual tax is $1,200 over three years, and the LLC-5 itself warns that registered LLCs may owe California’s $800 minimum Franchise Tax Board tax each year.
3. Florida LLC that opens offices in Georgia and North Carolina. Georgia CD 241 $235 plus North Carolina L-09 $250, $485 one-time. Three agents over three years: Northwest $1,125, Bizee $1,341, ZenBusiness $1,491. Each state’s annual report is separate.

How to keep the multi-state bill down

• Register where you need to, not everywhere. Out-of-state customers alone usually don’t require it. Check the state’s safe-harbor list, and ask a professional when it’s close.
• Form where you actually operate. If the business runs from one state, forming there avoids a foreign registration and a second agent.
• Be your own agent where you live, if you accept the public address. Pay for an agent only in the states where you can’t serve.
• Keep agents with one vendor. Northwest is $125/year per state ($375 over three) and $100/year per state at five or more, and publishes that it files the change and pays the state fee when you appoint it. Bizee standalone is $149/year ($447 over three). ZenBusiness standalone is $99 then $199 ($497 over three). Switching later is a change-of-agent filing in each state.
• Withdraw when you leave a state. An active foreign registration keeps the agent and annual report bills running. Withdrawal fees we found: Washington $0, North Carolina $10, Arizona $10, Colorado $10, Florida $25. Cancel the vendor only after the state shows the withdrawal.

Single-state renewal math is on the 3-year cost note.
