Ohio foreign LLC registration: how to register an out-of-state LLC in Ohio

What is a foreign LLC in Ohio?

"Foreign" has nothing to do with another country. To the Ohio Secretary of State, a foreign LLC is any limited liability company formed under the law of a jurisdiction other than Ohio. A Michigan LLC, a Delaware LLC, and an LLC formed in Ontario are all foreign LLCs here. The same goes for corporations: a corporation formed outside Ohio is a foreign corporation.

Ohio foreign LLC registration does not create a second company. Your LLC keeps its home-state formation, its home-state agent, and its home-state filings. The Ohio filing adds a record in Ohio that says the company is authorized to transact business here and names the person or company that accepts legal papers for it in Ohio.

This guide is the do-it-yourself walkthrough. If you would rather hand it off, our foreign business registration service prepares and files it with us named as your agent.

When does an out-of-state LLC have to register in Ohio?

ORC 1706.511(A) says a foreign LLC, or any of its series, must register with the Secretary of State before it transacts business in Ohio, and may not transact business here until the registration is approved. Corporations have the parallel rule in ORC 1703.03: no business in Ohio without an unexpired, uncancelled license.

Ohio does not define "transacting business" with one test. ORC 1706.512(A) works the other way, listing eleven activities that do not count on their own. In short form:

• Bringing, defending, or settling a lawsuit or other proceeding.
• Holding meetings or running internal affairs.
• Keeping bank accounts, or offices for transferring the company's own interests.
• Selling through independent contractors, or taking orders that are accepted outside Ohio.
• Borrowing, lending, taking security interests, and collecting the company's own debts.
• Owning real or personal property.
• An isolated transaction that is not one of a series, and business in interstate commerce.

Division (B) adds that being a member of an entity doing business in Ohio does not count by itself. Division (C) matters too: the list does not govern service of process, taxation, or regulation under other Ohio laws. A company can sit outside the registration rule and still owe Ohio tax.

Most real situations fall between the list and an obvious yes, such as a contractor with one Ohio job a year or a remote employee working from Cleveland. Those are judgment calls. Ask your attorney before you decide not to register. The rest of this guide assumes you have decided to file.

How to fill out Ohio Form 617, field by field

Form 617, Registration of a Foreign Limited Liability Company, is the current form (it replaced the old Form 533B). It does not ask for members or managers. It must be typed, single-sided on 8½ x 11 paper, with no Social Security or tax ID number.

Return-to block

Name, required email, mailing address, and phone of whoever should receive the filed document.

Service type

Check one box. Regular service has no extra fee and the form lists 3 to 7 business days. Expedited processing is available for an added state fee: 2 business days, 1 business day, or 4 hours with in-person delivery. A blank box means regular service.

Name in the jurisdiction of formation

Enter the LLC's legal name exactly as your home state shows it, including the designator. Ohio requires "limited liability company," "limited," "LLC," "L.L.C.," "ltd.," or "ltd" in the name.

Assumed name, if needed

Fill this in only if your legal name does not meet Ohio's naming rules in ORC 1706.07, usually because it is not distinguishable from a name already on Ohio's records. More on this below.

Jurisdiction of formation and effective date

Name the state or country where the LLC was formed. The effective date is optional; you may pick a delayed date up to 90 days after the Secretary of State receives the filing, which helps if your Ohio work starts on a known date.

Series information

Only for an LLC with series of assets. ORC 1706.511(C) requires a statement that series exist and whether each series' debts are enforceable only against that series' assets. Attach it on a separate single-sided sheet.

Original appointment of statutory agent

An authorized member, manager, or representative appoints the agent, giving the agent's name and a complete Ohio street address. P.O. boxes and private mailbox stores (CMRAs) are not accepted; the form's only exception is a P.O. box paired with a rural route number.

Acceptance of appointment

The agent signs here, as an individual or on behalf of the company serving as agent. A registration without the signed acceptance is incomplete.

Signature

At least one person authorized by the LLC signs and prints a name. If an entity signs, print its name on the signature line and have a representative sign on the "By" line with a title. A typed name counts as intent to sign.

To file on paper, mail regular-service filings to P.O. Box 670 and expedited filings to P.O. Box 1390, both Columbus, OH 43216, with a check or money order to the Ohio Secretary of State. The same filing can be made online through Ohio Business Central.

Foreign corporation license in Ohio: Form 530A and the 90-day certificate

A corporation does not use Form 617. A for-profit corporation files Form 530A, Foreign For-Profit Corporation Application for License; a nonprofit files Form 530B. Both carry a $99 state fee. Form 530A asks for more than the LLC form does:

• License type: permanent (good until cancelled or surrendered) or temporary (six months). The form notes no more than two temporary licenses in any three-year period, citing ORC 1703.13.
• The corporation's name, which must match its certificate of good standing, plus jurisdiction and date of incorporation and a mailing address.
• A principal office address. If it is outside Ohio, list an Ohio location if one exists; an Ohio office is not required.
• A brief purpose clause describing the business to be done in Ohio.
• A certificate of good standing or subsistence from the home state, under seal, stating the exact name, and dated no earlier than 90 days before the application is filed.
• The Ohio statutory agent's name and address, with the corporation's consent to service on the agent.
• Two yes/no questions: whether the application is being filed to prosecute or defend a lawsuit (a "yes" adds $250 under ORC 1703.29(A)), and whether a tax clearance certificate is attached. A corporation that began doing business in Ohio unlicensed before 2009 needs a tax commissioner certificate.
• An officer's signature with a notarized verification.

Order the good standing certificate last, so it does not go stale while the rest of the paperwork comes together. If your corporate name is taken in Ohio, the form points you to Form 591 to qualify under an assumed name.

How much does Ohio foreign registration cost, and how long does it take?

Regular service on these forms is listed at 3 to 7 business days. Expedited processing is available for an added state fee. Your home state also charges for its good standing certificate, and that fee and turnaround vary by state.

On top of the filing, the registration needs an Ohio statutory agent for as long as it stays in effect. Our agent service is $49 a year, the same price every year; see Ohio statutory agent pricing for what that covers.

Name conflicts, assumed names, and fictitious names in Ohio

Search the name on the Secretary of State's business search before you fill anything out. If your LLC's legal name does not comply with ORC 1706.07, ORC 1706.513(A) says the LLC cannot register until it adopts a compliant assumed name for use in Ohio. You put that name on Form 617 itself. Once registered under it, the LLC generally does not need a separate name registration, and it keeps using that name for its Ohio business.

Keep the two kinds of extra names apart. The assumed name on Form 617 is the name Ohio requires because your real one is unavailable. A brand name is the one you choose for marketing, like "Lakeshore Roofing" for "LSR Holdings LLC." Under ORC 1329.01, a name you do business under that is not your name of record is either registered as a trade name or reported as a fictitious name. The fictitious name report is due within 30 days after you first use the name, and the fee is $39. Our Ohio trade name and DBA service files either one.

If the LLC later changes its legal name at home, ORC 1706.511(D) requires a certificate of correction in Ohio, and ORC 1706.513(B) bars Ohio business under a new name that does not comply until the correction is made.

Do you need an Ohio statutory agent for a foreign LLC?

Yes. ORC 1706.09(A) says every foreign LLC with an effective Ohio registration must keep an agent for service of process in Ohio. Ohio calls it a statutory agent; most other states say registered agent. The agent must be an Ohio resident individual, or an entity with a business address in Ohio that is authorized to do business here. Your home-state registered agent qualifies only if it meets that rule and has an Ohio address. The full rule is in our guide to Ohio statutory agent requirements.

The requirement does not end with the filing. Under ORC 1706.09(L), if a company stops maintaining an agent and does not cure that within 30 days of the Secretary of State's notice, the foreign registration is cancelled. Reinstatement is possible within two years. Lawsuits can also be served through the Secretary of State when the agent cannot be found (ORC 1706.09(H)).

If you name us on Form 617, we sign the acceptance of appointment, and anything served on the company in Ohio comes to our office at 3416 Erhart Road in Litchfield. We scan it the same business day and publish it to your portal. Service of process notifies every authorized contact and escalates to a phone call if nobody acknowledges it. If you registered with another agent and want to move, changing your Ohio statutory agent takes one Form 521 filing.

What happens if you do business in Ohio without registering?

For a foreign LLC, ORC 1706.515 bars a lawsuit in an Ohio court to collect its debts until it has an effective registration, and a court can pause the case meanwhile. The LLC owes the state a fee set by the Secretary of State before a registration will be filed, and the attorney general can sue to collect it. Its acts stay valid, it can still defend itself, and members are not personally liable merely because it failed to register.

For a corporation, ORC 1703.29 keeps its contracts valid but blocks an Ohio lawsuit until it is licensed. Suing on a claim from its unlicensed period costs a $250 forfeiture, and a late applicant pays a 15 percent forfeiture on license fees and needs a tax commissioner certificate.

In practice, this surfaces when a customer stops paying. Registering before you need a court is simpler than registering mid-case.

Ohio tax registrations to consider after you register

The Secretary of State filing opens no Ohio tax account. Taxes run through the Ohio Department of Taxation, mostly via the Ohio Business Gateway. A short list for your accountant:

• Commercial activity tax (CAT): for 2025 and later, it applies to businesses with more than $6 million a year in Ohio taxable gross receipts. Out-of-state businesses are reached through a bright-line presence test, including $50,000 of Ohio property or payroll, or $500,000 of Ohio sales. The Department says to register within 30 days of exceeding the threshold.
• Employer withholding: an employer with Ohio workers registers on Form IT 1, and the Department's guide says within 15 days of when the withholding liability begins. School district income tax is withheld under the same account where it applies.
• Sales tax: a business selling taxable goods or services to Ohio customers may need a vendor's license.
• Municipal income tax: many Ohio cities tax wages and business income separately from the state.

Most of these registrations need a federal EIN. If the LLC does not have one yet, our EIN tax ID service gets it.

How to withdraw a foreign LLC from Ohio later (Form 618)

Registration does not lapse when Ohio work ends; it stays until it is cancelled. A foreign LLC files Form 618, the Certificate of Cancellation of Registration of a Foreign LLC, under ORC 1706.514. The fee is $50. Under ORC 1706.514(B), the certificate gives the LLC's name, Ohio registration number, any assumed name, and jurisdiction; the statutory agent's name and address, or a statement that no agent will be kept plus a street address where process may be mailed; and statements that the LLC is leaving Ohio, cancelling its registration, and withdrawing any assumed names.

The cancellation takes effect when the Secretary of State files it (ORC 1706.514(C)), but it does not end the authority of the agent the LLC appointed (ORC 1706.514(D)). Papers can still arrive afterward. A foreign corporation surrenders its license on Form 564 instead. Neither filing affects the company in its home state or closes Ohio tax accounts. Our dissolution and cancellation service prepares either one.
