To change your business address with the Ohio Secretary of State, file Form 521 ($25) if you’re updating your statutory agent’s address, or a Certificate of Amendment ($50 for corporations and LLCs) if you’re updating your principal office address. Both filings can be submitted online through Ohio Business Central or by mail to the Business Services Division in Columbus. Picking the right form is the part most owners get wrong, because Ohio tracks two separate addresses for every entity and they don’t update together.
Which Address Are You Changing?
Before you file anything, figure out which address is actually moving. The answer decides the form, the fee, and whether you need one filing or two.
Statutory Agent Address
Your statutory agent is the person or company designated to receive legal papers for your business. Ohio law requires every registered entity to keep an agent with a physical Ohio street address where someone authorized to accept service is generally present during business hours. A P.O. box does not qualify.
If your agent moves or you switch to a different agent, this is the record you update. It’s also the address where lawsuits get delivered, so an outdated one here can mean losing a case by default because you never saw the paperwork.
Principal Office Address
Your principal office is the business’s main location as it appears in your articles of incorporation or organization. The Secretary of State uses it for general correspondence and as a fallback when the agent can’t be reached. Changing it requires a formal amendment to your formation documents, not a Form 521.
If your business physically relocates and your statutory agent moves with it, you’ll likely need both filings: an amendment for the principal office and a Form 521 for the agent address.
Filing Form 521 for a Statutory Agent Change
Form 521 is the standard form for updating a statutory agent’s address or replacing the agent altogether. It covers nearly every entity type registered in Ohio, including domestic and foreign corporations, LLCs, limited partnerships, professional associations, cooperatives, and business trusts.1Ohio Secretary of State. Filing Forms and Fee Schedule Unincorporated nonprofit associations are the one exception and use a separate notification form.
The form itself is short. Enter your charter number and legal name at the top, then fill in either the new agent’s name and address or the corrected address for the existing agent. The signature required depends on the change: the entity’s authorized representative signs when appointing a new agent, and the agent can sign for a straight address correction. Enter the address exactly the way you want it in public records, because the Secretary of State publishes it in a searchable database.
The filing fee is $25.1Ohio Secretary of State. Filing Forms and Fee Schedule
Amending Your Principal Office Address
A Form 521 filing will not move your principal office. That change requires a Certificate of Amendment, and the specific form depends on your entity type:1Ohio Secretary of State. Filing Forms and Fee Schedule
- Domestic for-profit corporations file Form 540 or 541. The fee is $50.
- Domestic LLCs file Form 611, the Certificate of Amendment or Restatement. The fee is $50.
- Domestic partnerships file Form 545, the Amendment/Cancellation of Partnership Statement. The fee is $25.
These fees are separate from any statutory agent update. If both addresses are changing, expect to pay both.
Foreign Entities Registered in Ohio
Out-of-state businesses licensed to operate in Ohio follow a slightly different path for principal office changes. Foreign for-profit and nonprofit corporations file Form 565, the Certificate of Amendment to Foreign Corporation Application for License, at a fee of $50.1Ohio Secretary of State. Filing Forms and Fee Schedule The form handles changes to both the principal office and any Ohio office address listed on the original application.
Statutory agent updates work the same for everyone. A foreign entity uses Form 521 at the same $25 fee as a domestic Ohio business.

What You’ll Need Before You Start
Have these on hand:
- The business’s exact legal name as it appears in your original formation documents.
- Your charter or registration number. If you don’t have it, look it up through Ohio Business Central.
- The complete new physical street address with any suite or unit number and zip code. For a statutory agent, this must be an Ohio street address where someone can accept service in person.
- If you’re appointing a new agent, that agent’s name and written consent to serve.
Expedited Processing
Standard filings take several business days depending on volume. Three expedited tiers are available on top of the base fee:4Ohio Legislative Service Commission. Ohio Administrative Code Rule 111:1-2-01 – Corporations Expedited Filing
- Level 1, $100: processed within two business days of receipt.
- Level 2, $200: processed within one business day of receipt.
- Level 3, $300: processed within four business hours of receipt.
These add to the base filing fee. A Form 521 with Level 2 expedited service runs $225 total.
What Happens If You Don’t Update
Letting your statutory agent information lapse can end with your business being canceled. When the Secretary of State discovers the problem, the office mails a notice to the corporation at its last known address. If the default isn’t corrected within 30 days of that mailing, the articles are canceled automatically with no further notice required.5Ohio Legislative Service Commission. Ohio Revised Code 1701.07 – Statutory Agent – Cancellation and Reinstatement of Articles
A canceled entity can be reinstated within two years by filing a reinstatement application, appointing an agent, and paying a $25 fee.6Ohio Legislative Service Commission. Ohio Revised Code 111.16 – Filing Fees The real damage happens during the gap. While the entity is canceled, you may lose the ability to enforce contracts, file lawsuits, or protect your business name, and reinstatement doesn’t automatically undo every consequence.
Beyond the state record, an outdated address can mean missed IRS correspondence, missed local tax notices, and missed service of process. Courts have entered default judgments against businesses properly served at a registered agent address where nobody was there to receive the papers.
Tell the IRS Separately
An Ohio filing does not update your federal record. File IRS Form 8822-B, Change of Address or Responsible Party — Business, to update your address with the IRS.7Internal Revenue Service. Change of Address or Responsible Party – Business There is no penalty for skipping the form on a simple address change, but the IRS will keep sending mail to the old address, and penalties and interest on a missed notice keep accruing whether or not it reached you.8Internal Revenue Service. Form 8822-B Change of Address or Responsible Party – Business
A change in the business’s responsible party carries a firmer deadline: the same form must be filed within 60 days.
Other Places to Update
Once the Secretary of State and IRS filings are done, work through the rest:
- Ohio Department of Taxation, for franchise tax, sales tax, and other state accounts.
- County and municipal offices holding your local permits or licenses. Processes and fees vary by jurisdiction.
- Banks, credit lines, and merchant processors tied to the business.
- Any Ohio professional or occupational licensing board your business reports to.
- SAM.gov, if you hold federal contracts or grants. Address changes there require IRS and CAGE validation and take roughly 10 to 12 business days to process.
