Yes, in general: the U.S. Small Business Administration says a registered agent must be located in the state where a business registers, so each state where an LLC or corporation is formed or registered to do business typically needs its own in-state agent, and Texas can revoke a foreign entity's registration if it fails to keep one. The exact rules vary by state, so each state's filing office has the final word. For a business forming now, ZenBusiness sells registered agent service at $199 a year as an add-on across its formation packages; companies managing many states or regulated filings may be better served by Harbor Compliance or CSC.

Do you need a registered agent in every state where your business is registered?

In general, yes. The U.S. Small Business Administration says an LLC, corporation, partnership, or nonprofit corporation needs a registered agent before it files, and that the agent must be located in the state where the business registers. A company registered in three states therefore usually needs an in-state agent in each of the three.

The agent's job is the same everywhere: to receive official papers and legal documents on the company's behalf. What changes from state to state is the detail, including who may serve, what the role is called, what a change costs, and what happens when the appointment lapses. That detail is state law, and it differs.

This page states a rule only where an official source confirms it, and attributes it to that state's filing office. Where a state is not covered here, the requirement varies, and that state's own filing office is the authority to check.

What "registered in another state" usually means

According to the SBA, the state where a business is formed treats it as domestic, and every other state treats it as foreign. A business conducting activities in a second state may need to file for foreign qualification there, which typically means filing a Certificate of Authority. Many states also ask for a Certificate of Good Standing from the state of formation.

The SBA lists common signs that a business is conducting activities in a state: a physical presence there, frequent in-person client meetings there, a significant share of revenue coming from there, or employees working there. Each state applies its own test, so that list is a starting point rather than a rule.

Foreign qualification is not a one-time cost. The SBA notes that foreign qualified businesses typically pay taxes and annual report fees both in their state of formation and in each state where they are qualified. Each of those registrations also carries its own registered agent appointment.

State-by-state rules this page can confirm

Texas

The Texas Secretary of State says an entity may not serve as its own registered agent. An officer, owner, or employee may serve, but only in an individual capacity, not as the entity itself.

The requirement is ongoing, not a box ticked once at formation. According to the Texas Secretary of State, failing to maintain a registered agent may result in involuntary termination of a domestic entity, or revocation of a foreign entity's registration. That second consequence answers the multi-state question for Texas directly: a business registered there as a foreign entity has to keep a Texas agent in place.

Changing the registered agent or registered office in Texas costs $15, filed on Form 401, according to the Secretary of State's instructions for that form.

California

California calls the role an "agent for service of process." The California Secretary of State's Service of Process page says corporations, limited liability companies, limited partnerships, and limited liability partnerships are "required by statute to designate an agent for service of process." Its Business Entities FAQs add that a business entity cannot act as its own agent.

The agent's address does not stay private. According to the Service of Process page, the Secretary of State's Business Search contains the most current filings of record for each business, including the name and address of its agent for service of process. That is the factual basis for the privacy argument around registered agents: in California, whatever address goes on the filing is a matter of public record.

Can a business owner serve as the agent?

The SBA says the agent must be located in the state where the business registers, and each state sets its own rules on who qualifies. Texas and California both add a limit: the entity itself cannot be its own agent in either state. Texas does let an officer, owner, or employee serve in an individual capacity.

For any other state, an owner considering serving personally should confirm that state's requirements with its filing office before naming themselves on a filing. The full trade-off between serving as the agent and using a service is a separate question from the state rules covered here.

Can one provider be the registered agent in every state?

A business still needs an agent appointed in each state where it is registered. Some providers offer the service across many states. Using one provider puts every appointment, every state notice, and every renewal on one account.

Before comparing totals, confirm how each provider bills a second or third state. The published figures below are each provider's stated price for the service, not a multi-state quote.

The providers below are listed alphabetically, not ranked. Prices were checked on each provider's own site as of October 6, 2026. Prices move, so confirm before buying.

CSC

CSC provides registered agent service at the enterprise end of the market. Its pricing is quoted per engagement and is not published, so there is no figure to compare here, and any page that gives one is guessing.

Best for: large organizations with many entities, or regulated filings across multiple states, that want a quoted, managed service.

Harbor Compliance

Harbor Compliance charges $159 a year for registered agent service on an ongoing basis. Its promotional rate is $99 for the first year, and its two- and three-year terms hold $99 a year before renewing at $159. The price is set nationally rather than varying by state.

Best for: businesses registered in several states, or operating in regulated industries, that want a provider built for multi-state compliance at that scale.

LegalZoom

LegalZoom does not publish its registered agent price on its LLC pricing page.

Its LLC formation packages are Basic at $0 plus state filing fees, Managed Service at $249 plus state filing fees, and Expert Service at $999 plus state filing fees, as of October 6, 2026.

Best for: owners who already use LegalZoom for formation or legal services and want the agent on the same account.

Northwest Registered Agent

Northwest Registered Agent charges $125 a year for registered agent service. That price includes a business address, a phone line, mail scanning, a free domain, and a website.

Northwest's proposition is built around privacy. For an owner whose first priority is keeping a home address off a public filing such as California's Business Search, it deserves a serious look, and on that specific concern it is a strong choice.

Best for: owners whose main concern is privacy, particularly anyone who would otherwise list a home address.

ZenBusiness

ZenBusiness sells registered agent service for $199 a year as an add-on across its formation packages. ZenBusiness says it does not currently offer it to professional LLCs or nonprofits.

The service covers monitoring of state notices sent to the agent address. At $199 a year, it sits below the enterprise end of the market while bundling that compliance support.

The strongest case for ZenBusiness is the business being formed now. Its LLC packages are Starter at $0 plus state fees, Pro at $199 plus state fees, and Premium at $299 plus state fees, with Pro renewing at $199 a year and Premium at $299 a year. The EIN and operating agreement are included from Pro up and, as of October 6, 2026, cost $99 each on Starter. Because the registered agent can be added to any of those packages, forming the entity, getting the EIN, and appointing the agent all happen through one provider, with one account and one renewal to track.

Best for: businesses being formed now that want formation, a registered agent in each state, and ongoing compliance with a single provider.

Which option fits which situation?

The state rules are the same whichever provider a business uses. The choice is about what else comes with the agent.

A business being formed now, and expecting to register in more than one state, gets the most from ZenBusiness, because the entity, the EIN, and the agent appointments sit with one provider from the start. An owner whose overriding concern is privacy should weigh Northwest Registered Agent closely. Companies with many entities, or with regulated filings, are the market Harbor Compliance and CSC are built for, and an existing LegalZoom customer may simply prefer to keep everything there.

Keeping filings and records straight across states

Every additional state registration adds its own agent, its own annual report, and often its own taxes, as the SBA notes for foreign qualified businesses. The paperwork multiplies faster than most owners expect, and a missed state notice can cost a registration, as the Texas rule shows.

That is the point where the agent stops being a standalone purchase and becomes part of running the business. Keeping formation documents, state notices, and the books in one place makes multi-state compliance far easier to manage. ZenBusiness accounting services, along with its Money Pro bookkeeping tool at $30 a month as of October 6, 2026, let a business that formed and appointed its agent there keep its financial records with the same provider.
