Change Registered Agent in Ohio

When Is a Change of Registered Agent Required in Ohio?

A filing entity must file a statutory agent update with the Ohio Secretary of State whenever it needs to change its statutory agent, its agent’s address, or both. Under the Ohio Revised Code (ORC) § 1701.07, every domestic for-profit corporation is required to continuously maintain a statutory agent — Ohio’s term for a registered agent — authorized to accept service of process, notices, and demands on the entity’s behalf. The same obligation applies to nonprofit corporations under ORC § 1702.06, limited liability companies under ORC § 1706.09, limited partnerships under ORC § 1782.04, partnerships and limited liability partnerships that maintain an effective statement of partnership authority under ORC § 1776.07, foreign for-profit and nonprofit corporations licensed in Ohio under ORC § 1703.041, and business trusts and real estate investment trusts under their respective chapters of the Ohio Revised Code. Whether the change is prompted by an agent’s resignation, a relocation, or a voluntary decision to switch to a commercial agent service, each of these statutes uses the word “forthwith” — the entity must act immediately to appoint a replacement and file the required form with the Secretary of State. Failure to maintain a statutory agent can lead to involuntary cancellation of a domestic entity’s articles or cancellation of a foreign entity’s license to transact business in the state.

The following circumstances trigger the requirement to file a change:

• The current statutory agent resigns by filing a notice of resignation with the Secretary of State
• The current statutory agent dies or moves out of Ohio
• The agent’s street address changes due to a physical move, postal renaming, or other cause
• The statutory agent is no longer available at the registered address during normal business hours
• The entity voluntarily selects a new statutory agent, such as when switching to a professional agent service
• The agent no longer consents to serve

Ohio law does not distinguish between voluntary and involuntary changes — the filing requirement and the form used are the same regardless of the reason.

 

Grounds for Changing Your Registered Agent in Ohio

The most common reasons an Ohio entity files a statutory agent update fall into a handful of recurring scenarios. The table below summarizes each ground and identifies the filing required.

Ground	Filing Required
Statutory agent resigns	Form 521 – Statutory Agent Update (or Form 545 for LLPs and partnerships) to appoint a replacement
Statutory agent dies or moves out of Ohio	Form 521 to appoint a new agent
Agent’s street address changes	Form 521 (agent address update) or Form 526A if agent represents six or more entities
Entity switches to a professional statutory agent service	Form 521 to appoint the new service and revoke the prior agent
Agent no longer available during normal business hours	Form 521 to designate a qualifying replacement
Agent no longer consents to serve	Form 521 to appoint a new agent
Entity changes its own registered office address	Form 521 to report the new address

The statutory agent’s name and address are part of the public record maintained by the Secretary of State and can be searched through the state’s business search tool. Any outdated or inaccurate information must be corrected promptly by filing the appropriate form.

Ohio Registered Agent Change Requirements

Before filing a statutory agent update, the entity must confirm that the new agent and the new address satisfy Ohio’s eligibility requirements.

Eligibility of the new statutory agent:

• Option A – Organization: A domestic or foreign corporation, nonprofit corporation, limited liability company, partnership, limited partnership, limited liability partnership, limited partnership association, professional association, business trust, or unincorporated nonprofit association that has a business address in Ohio. If the agent is an entity other than a domestic corporation, it must meet the requirements of Title XVII of the Revised Code for its entity type to transact business or exercise privileges in Ohio. The filing entity itself cannot serve as its own statutory agent.
• Option B – Individual: A natural person who is a resident of Ohio and has a physical street address in the state.

Address requirements:

The statutory agent’s address must be a physical street address in Ohio — specifically, the agent’s primary residence (if an individual) or usual place of business (if an organization). ORC § 1701.07(C)(2) defines “usual place of business” as “a place in this state that is customarily open during normal business hours and where an individual is generally present who is authorized to perform the services of a registered agent.” A post office box does not qualify, “regardless of whether that post office box has an associated street address.” Commercial mail receiving agencies (CMRAs) and private mailbox services are likewise not permitted.

Consent and acceptance of the new statutory agent:

Ohio requires the new statutory agent to sign a written acceptance of the appointment. For domestic for-profit corporations, ORC § 1701.07(B) provides that the entity must file with the Secretary of State “a written appointment of the agent that is signed by any authorized officer of the corporation and a written acceptance of the appointment that is either the original acceptance signed by the agent or a photocopy, facsimile, or similar reproduction of the original acceptance signed by the agent.” The same acceptance requirement applies to LLCs under ORC § 1706.09(B)(2) and to other entity types under their respective statutes. The written acceptance is filed together with Form 521 as part of the statutory agent update.

Note: Including a person’s name or address on a business entity filing without that person’s consent may subject the filer to administrative action by the Secretary of State, including cancellation of the unauthorized filing.

Execution:

The statutory agent update must be signed by an authorized officer of the entity. For a for-profit corporation, ORC § 1701.07(K) provides that the written appointment “shall be signed by any authorized officer of the corporation.” For an LLC, it must be signed by an authorized representative. The filing need not be notarized.

How to File a Statement of Change of Registered Office/Agent

The change is made by filing Form 521 – Statutory Agent Update with the Ohio Secretary of State. Form 521 is a multi-purpose form that accommodates new agent appointments, agent address updates, and agent resignations for corporations, LLCs, limited partnerships, partnerships, business trusts, real estate investment trusts, and cooperative associations. For limited liability partnerships and general partnerships that need to change their statutory agent (rather than resign one), the proper filing is Form 545 – Amendment / Cancellation of Partnership Statement, which amends the partnership’s statement of qualification or partnership authority to reflect the new agent.

The information required on Form 521 includes:

1. Entity information: The entity’s legal name and the Secretary of State file number.
2. Current agent information: The name and address of the current statutory agent on record.
3. Type of update: Whether the filing is a new appointment of a statutory agent, a change of the agent’s address, or a resignation of the agent.
4. New agent designation: If appointing a new agent, the full name and Ohio street address of the new statutory agent.
5. Written acceptance: The signature of the new statutory agent accepting the appointment, filed as part of the form or attached separately.
6. Authorized signature: The signature of an authorized officer or representative of the entity. If the filing is a resignation, the resigning agent must sign.

Note: When filing online through the Ohio Business Central portal, the system collects the required information directly. Follow the portal’s prompts rather than uploading the PDF form, unless the portal specifically requests an attachment.

On acceptance by the Secretary of State, the statutory agent update takes effect, and the entity’s records are updated accordingly.

Filing Method: Online vs. Mail

Ohio permits the statutory agent update to be filed online, by mail, or in person at the Secretary of State’s Client Service Center.

Method	Details
Online	File through Ohio Business Central. Available 24 hours a day. An account must be created to file. Payment by credit card (Visa, Mastercard, Discover, American Express) or debit card.
Mail	Send Form 521 and payment to: Ohio Secretary of State, P.O. Box 670, Columbus, OH 43216 (or to the street address below). Payment by check or money order payable to “Ohio Secretary of State.”
In Person	Deliver Form 521 to the Client Service Center at 180 Civic Center Drive, Columbus, OH 43215. Payment by credit card, debit card, check, money order, or cash.

Online filing is the fastest and most convenient method. Regular (non-expedited) filings are typically processed within three to seven business days. Expedited processing is available for an additional fee above the standard filing fee: $100 for two-business-day processing, $200 for one-business-day processing, and $300 for four-business-hour processing, as established by Ohio Administrative Code Rule 111:1-2-01. Only Level 1 ($100) expedited requests may be submitted by mail; Levels 2 and 3 require in-person delivery.

Registered Agent Change Filing Fees by Entity Type

The filing fee for a statutory agent update is set by ORC § 111.16(R)(1), which charges $25 for filing a change of agent, resignation of agent, or change of agent’s address. This fee applies uniformly to all entity types that file Form 521 or Form 545.

Entity Type	Form	Filing Fee
Domestic for-profit corporation	Form 521	$25
Domestic nonprofit corporation	Form 521	$25
Domestic professional association	Form 521	$25
Domestic limited liability company	Form 521	$25
Domestic limited partnership	Form 521	$25
Domestic limited liability partnership	Form 545	$25
General partnership (with statement of partnership authority)	Form 545	$25
Domestic cooperative association	Form 521	$25
Business trust	Form 521	$25
Real estate investment trust	Form 521	$25
Foreign for-profit corporation	Form 521	$25
Foreign nonprofit corporation	Form 521	$25
Foreign limited liability company	Form 521	$25
Foreign limited partnership	Form 521	$25
Foreign limited liability partnership	Form 545	$25

Payment methods accepted by the Secretary of State include credit card (Visa, Mastercard, Discover, American Express) and debit card for online and in-person filings, check or money order for mail filings, and cash for in-person filings. There is no filing fee for the statutory agent resignation itself — a resignation filed by the agent on Form 521 also costs $25 under ORC § 111.16(R)(1).

Effective Date of a Registered Agent Change in Ohio

A statutory agent update filed with the Ohio Secretary of State is effective upon filing and acceptance. Ohio does not provide a delayed-effective-date or future-event option for this type of filing. Once the Secretary of State processes and accepts the form, the entity’s statutory agent record is immediately updated.

Immediate effect: The default and only effectiveness rule for a statutory agent update is that the change takes effect when the Secretary of State accepts the filing. For filings processed through regular (non-expedited) channels, this typically occurs within three to seven business days of receipt.

Expedited processing: If faster effectiveness is needed, the filer may pay for expedited processing. Level 1 (two business days, $100 additional) is available by mail or in person. Level 2 (one business day, $200 additional) and Level 3 (four business hours, $300 additional) require in-person delivery under Ohio Administrative Code Rule 111:1-2-01.

Upon acceptance, the statutory agent update replaces the agent information previously on file, and the new agent’s name and address become the official record for service of process purposes. The former agent’s authority to receive service on behalf of the entity terminates.

Changing the Registered Agent Address Without Changing the Agent

When a statutory agent’s own address changes — but the same individual or organization continues to serve — the agent or the entity may update the address without appointing a new agent. For a single entity, this is done by filing Form 521 – Statutory Agent Update and selecting the address-change option rather than the new-appointment option. The fee is the same: $25.

For agents who represent six or more entities, Ohio provides a bulk updating mechanism. Form 526A – Bulk Agent Name and/or Address Change allows a statutory agent to update its own name or address across all represented entities in a single filing. This form cannot be used to switch to a different agent — it only updates the existing agent’s information. The fee structure for Form 526A is set by ORC § 111.16(R)(2): a flat fee of $125 plus $3 per entity record being changed.

The following table compares the single-entity approach and the bulk agent approach:

Feature	Form 521 (Single Entity)	Form 526A (Bulk Agent Update)
Filed by	Entity or agent	Agent only
Purpose	Appoint new agent, update address, or resign	Update agent’s own name or address across multiple entities
Can appoint a different agent	Yes	No
Minimum entities required	1	6
Fee	$25 per entity	$125 + $3 per entity record
Signed by	Authorized officer of entity (or agent if resigning)	Agent

Ohio also offers Form 526B – Bulk Agent Name and/or Address Standardization, which allows an agent to correct or standardize its address format across multiple entity records for a flat fee of $125 with no per-entity charge. This form is used for address formatting corrections only, not for actual address changes.

Note: Changes made through Form 526A or 526B do not update any trade names, fictitious names, or trademark registrations where the agent is listed as the registrant. Those records must be updated separately using the appropriate trade name or trademark update form.

What Happens After the Change Is Filed

Once the Secretary of State accepts the statutory agent update, several consequences follow:

• The entity’s statutory agent and address information in the Secretary of State’s records is updated immediately upon acceptance.
• The new agent’s name and address become part of the entity’s public filing history and are searchable through the Secretary of State’s business search tool.
• The former agent’s authority to receive service of process on behalf of the entity terminates.
• Service of process directed to the old agent’s address will no longer be effective service on the entity; all future service must be delivered to the new agent at the new address.
• The Secretary of State returns evidence of the accepted filing to the submitter.
• If the entity filed the update to revoke the prior agent’s appointment (under ORC § 1701.07(G) for corporations or equivalent provisions for other entity types), the filing simultaneously appoints the new agent and revokes the former agent.

Changing a Registered Agent for a Foreign Entity Registered in Ohio

A foreign entity licensed or registered to transact business in Ohio must maintain a statutory agent under the same requirements that apply to domestic entities. For foreign for-profit corporations and foreign nonprofit corporations, ORC § 1703.041 establishes the obligation and sets forth the same eligibility standards — a natural person who is an Ohio resident or a qualifying entity with an Ohio business address. Foreign LLCs are governed by ORC § 1706.09, and foreign limited partnerships by ORC § 1782.04.

A foreign entity changes its statutory agent by filing the same Form 521 – Statutory Agent Update used by domestic entities. The same eligibility requirements, acceptance requirements, street address requirements, execution requirements, filing methods, and $25 filing fee apply. Foreign LLPs change their agent through Form 545, also at a $25 fee.

If a foreign corporation fails to appoint a replacement agent after the death, resignation, or departure of its designated agent, ORC § 1703.15 authorizes the Secretary of State to cancel the foreign corporation’s license to do business in Ohio after providing thirty days’ written notice. The corporation may apply for reinstatement within two years of cancellation by paying a $25 reinstatement fee under ORC § 111.16(Q). During the period a foreign entity lacks a statutory agent, the Secretary of State may be served as the entity’s agent under ORC § 1703.19, exposing the entity to the risk of default judgment.

Frequently Asked Questions About Changing a Registered Agent in Ohio

How long does it take to change a registered agent in Ohio?

The Ohio Secretary of State does not guarantee a specific processing time for standard filings, but regular submissions are typically processed within three to seven business days. Expedited processing is available for an additional fee: $100 for two-business-day turnaround, $200 for one-business-day turnaround, or $300 for four-business-hour turnaround under Ohio Administrative Code Rule 111:1-2-01. Online filings through Ohio Business Central are generally processed more quickly than mail submissions. For questions about current processing times, contact the Business Services Division at (614) 466-3910.

Do I need to notify my current registered agent before changing?

Ohio law does not impose a statutory obligation on the entity to notify the outgoing statutory agent before filing the change. When an entity files Form 521 to appoint a new agent and revoke the prior appointment, the change is effective upon acceptance by the Secretary of State. Many entities choose to notify the outgoing agent as a business courtesy. If the outgoing agent wishes to end the relationship independently, the agent may file a resignation through Form 521, selecting the resignation option, which terminates the agent’s authority thirty days after filing (or sixty days for nonprofit corporations under ORC § 1702.06(F) and foreign corporations under ORC § 1703.041(E)).

Can I change my registered office address without changing the registered agent?

Yes. Form 521 – Statutory Agent Update allows the filer to update the agent’s address without appointing a different agent. Select the address-change option on the form, provide the new Ohio street address, and submit the form with the $25 filing fee. If the statutory agent represents six or more entities and the same address change applies to all of them, the agent may file Form 526A instead for a consolidated update.

What is the agent-initiated address change form and when is it used?

Form 526A – Bulk Agent Name and/or Address Change is filed by the statutory agent — not the entity — when the agent changes its own name or address while continuing to serve. It is available only for agents who represent six or more entities and cannot be used to appoint a different agent. The fee is $125 plus $3 per entity record. The form is authorized under ORC § 111.16(R)(2). For agents representing fewer than six entities, the agent or the entity files a separate Form 521 for each entity at $25 per filing.

Is there a penalty for not filing a change of registered agent?

Ohio requires every filing entity to continuously maintain a statutory agent. If an entity fails to appoint a replacement agent or to file a change of address after the agent resigns, dies, or relocates, the Secretary of State sends notice to the entity by mail. Under ORC § 1701.07(M), unless the default is cured within thirty days (or any further period the Secretary of State grants), the entity’s articles are cancelled without further notice. A cancelled entity loses standing to maintain lawsuits in Ohio courts and faces the risk of default judgments if process is served on the Secretary of State as substitute agent.

Can I change my registered agent and the registered office address in the same filing?

Yes. Form 521 permits changing the statutory agent, the agent’s address, or both in a single filing. When appointing a new agent whose address differs from the prior agent’s address, both fields are updated simultaneously. Only a single $25 filing fee applies regardless of whether the filer changes the agent, the address, or both.

What happens if my registered agent resigns?

A statutory agent may resign by filing a written notice of resignation with the Secretary of State on Form 521. The resigning agent must sign the form and must send a copy of the notice to the entity at the entity’s current or last known principal office address on or prior to the date the notice is filed. For domestic for-profit corporations under ORC § 1701.07(F), the agent’s authority terminates thirty days after the filing. For nonprofit corporations under ORC § 1702.06(F), the authority terminates sixty days after filing. Once the resignation is filed, the Secretary of State sends notice to the entity. The entity must then promptly file Form 521 to appoint a replacement agent — failure to do so within the Secretary of State’s notice period can result in cancellation of the entity’s articles.

Does the new registered agent need to sign the change form?

Yes. Unlike some states that require only the entity’s signature, Ohio requires the new statutory agent to sign a written acceptance of the appointment. ORC § 1701.07(B) provides that the entity must file “a written acceptance of the appointment that is either the original acceptance signed by the agent or a photocopy, facsimile, or similar reproduction of the original acceptance signed by the agent.” The acceptance is included as part of the Form 521 submission or attached separately. The entity’s authorized officer also signs the form to authorize the change.

Can I use a P.O. Box for the new registered office address?

No. The statutory agent’s address must be a physical street address in Ohio — either the agent’s primary residence or the agent’s usual place of business. ORC § 1701.07(C)(2) provides that “usual place of business” does not include “a post office box, regardless of whether that post office box has an associated street address.” Commercial mail receiving agencies and private mailbox services are also prohibited per the Secretary of State’s FAQ guidance. The address must be a location in Ohio that is customarily open during normal business hours with an authorized individual present to accept service.

Is the filing fee the same whether I file online or by mail?

Yes. The filing fee for a statutory agent update is $25 regardless of whether the filing is submitted online through Ohio Business Central, by mail, or in person. There is no surcharge for online filing. In-person filers may pay by cash, check, money order, credit card, or debit card. Mail filers must pay by check or money order payable to “Ohio Secretary of State.” Online filers pay by credit card or debit card through the Ohio Business Central portal.
