Ohio calls the registered agent a statutory agent, and every Ohio LLC must continuously maintain one in the state under Ohio Revised Code 1706.09. The agent can be an Ohio resident or a business with an Ohio business address, and a P.O. box never counts as its place of business. Changing your statutory agent with Form 521 costs $25 as of October 2026. For a professional agent, Mainstay Filing ($149 a year) is our first pick, and OH Registered Agent.org costs less at $99.

What is a statutory agent in Ohio?
Most states say “registered agent.” Ohio’s LLC Act says “agent for service of process,” and the Secretary of State’s forms say “statutory agent.” All three mean the same job: the person or company that accepts lawsuits, subpoenas and official notices on the LLC’s behalf.
ORC 1706.09 requires each LLC to maintain one continuously in Ohio. That word “continuously” is the important part, and it applies from the day the articles are filed for as long as the company exists. A statutory agent who moves away, retires or closes up shop without a replacement leaves the LLC out of compliance and without a reliable way to learn it has been sued.
Who can be a statutory agent in Ohio?
Under ORC 1706.09(A), the agent must be one of two things:
- A natural person who is a resident of Ohio, such as a member, manager, employee, attorney or accountant
- An entity with a business address in Ohio: a domestic or foreign corporation, nonprofit corporation, LLC, partnership, limited partnership, LLP, limited partnership association, professional association, business trust or unincorporated nonprofit association
Foreign entities serving as agents must be authorized to do business in Ohio.
No P.O. boxes Ohio’s statute is unusually specific on this point. The agent’s usual place of business “does not include a post office box, regardless of whether that post office box has an associated street address.” Box-style addresses at mailing stores, which often look like street addresses, do not qualify.
Can you be your own statutory agent in Ohio?
Yes, if you live in Ohio. An individual member or manager who is an Ohio resident can be named as the statutory agent, using a real Ohio address.
Weigh it against these points before deciding:
- Your name and address become part of the public business record
- You need to be reachable at that address to receive legal papers
- Owners who live in Pennsylvania, Indiana, Michigan, Kentucky or West Virginia cannot serve personally
- Moving means a $25 Form 521 filing, and with no annual report in Ohio, there is no routine filing that reminds you to update it
How much does it cost to change a statutory agent in Ohio?
The Secretary of State’s Form 521, Statutory Agent Update, costs $25 as of October 2026. ORC 111.16(R)(1) sets the same $25 for a change of agent, a resignation of agent, or a change of the agent’s address. Form 521 is shared across entity types, including LLCs.
Ohio is otherwise inexpensive to maintain: $99 to form an LLC and no annual report or franchise tax filing with the Secretary of State. That makes the statutory agent fee one of the few recurring costs. Mainstay’s Ohio LLC cost guide lays out the totals.
How to change your statutory agent in Ohio
- Pick the new statutory agent and confirm it qualifies: an Ohio resident or an eligible entity with an Ohio business address, and no P.O. box.
- Download Form 521 from the Secretary of State, or file the same update online through Ohio Business Central.
- Enter the LLC’s name and charter or registration number, then the new agent’s name and Ohio address.
- Sign as an authorized representative and pay the $25 fee.
- Search your business on the Secretary of State’s site to confirm the new agent appears.
Why Ohio LLCs should check their agent from time to time
Ohio’s lack of an annual report is convenient, but it removes the yearly checkpoint many states rely on. In states with annual reports, owners see their agent information every year. In Ohio, an LLC formed years ago may still list a founder’s old address or an agent that has since closed. Looking up your record every year or so, and filing Form 521 if anything has changed, keeps legal papers flowing to the right place.
Questions to ask before you hire a statutory agent 1. Where exactly is your Ohio office, and is someone there during business hours? 2. How will I find out that papers were served, and can I see a copy the same day it is processed? 3. What will I pay at renewal, not just in the first year? 4. Will you file Form 521 for me, or do I need to handle the switch myself? 5. If I later register in other states, can you serve as my agent there too?

FAQs
Does an Ohio LLC need a registered agent?
Yes. Ohio calls it a statutory agent. Ohio Revised Code 1706.09 requires every Ohio LLC to continuously maintain an agent for service of process in the state. The agent must be an Ohio resident or an eligible business entity with an Ohio business address, and a P.O. box does not count as its place of business.
How much does it cost to change a statutory agent in Ohio?
The Ohio Secretary of State charges $25 to file Form 521, Statutory Agent Update, as of October 2026. ORC 111.16 sets the same $25 for a change of agent, a resignation of agent, or a change of the agent’s address. The update can be filed on paper or online.
What is the difference between a statutory agent and a registered agent?
In Ohio there is no practical difference. “Statutory agent” is the term the Ohio Secretary of State uses for the person or company that accepts service of process for a business, which most other states call a registered agent. The Ohio LLC Act itself uses the phrase “agent for service of process.”
Can I be my own statutory agent in Ohio?
Yes, if you are an Ohio resident. A member or manager who lives in Ohio can be named as the LLC’s statutory agent at a real Ohio address. That address becomes public, and you must be available to receive legal papers there. Owners in other states need an Ohio resident or a qualifying business.
Can an Ohio statutory agent use a P.O. box?
No. ORC 1706.09 says an agent’s usual place of business does not include a post office box, even if the box has an associated street address. The agent needs an actual Ohio address where legal documents can be delivered in person.
Do Ohio LLCs file annual reports?
No. Ohio does not require LLCs to file an annual report with the Secretary of State, and there is no franchise tax filing there either. Because there is no yearly filing, it is worth checking your statutory agent information periodically and filing Form 521 for $25 if it has changed.
How much does an Ohio statutory agent service cost?
Providers set their own fees. Mainstay Filing, our top recommendation, charges $149 a year and renews at $149, with the switch included. OH Registered Agent.org charges $99 a year. Ohio’s own charge is the $25 Form 521 filing when you change agents.
