To change your LLC address in Illinois, file a Statement of Change of Registered Agent and/or Registered Office with the Illinois Secretary of State if your registered office moved, or file Articles of Amendment if your principal place of business moved. If both addresses changed, you need both filings. After the state filing goes through, notify the IRS and the Illinois Department of Revenue separately, because updating your Secretary of State record does not touch the tax agencies.
Figure Out Which Address Changed
Illinois LLCs carry two addresses in the state’s records, and they take different forms.
The registered office is the Illinois street address where your registered agent accepts lawsuits and state notices during business hours. It has to be a physical Illinois address; a P.O. Box alone will not qualify.1Illinois Secretary of State. Information for Forming an LLC Online The registered agent’s business address must match this address.2Illinois General Assembly. Illinois Code 805 ILCS 180/1-36 – Change of Registered Office or Registered Agent
The principal place of business is where the company actually operates or keeps its records. It does not have to be in Illinois. Changing it means filing Articles of Amendment under Section 1-40 of the Limited Liability Company Act, not the Statement of Change.
Most of this article covers the registered office change, because that is the filing that keeps you reachable for legal service. The section on Articles of Amendment covers the principal-office side.
What to Have Ready Before You File
The Secretary of State rejects filings that do not match its database, so gather these first:
- The LLC’s exact legal name, including punctuation and the designator you chose at formation (“LLC,” “L.L.C.,” or “Limited Liability Company”).
- Your eight-digit Illinois file number, which appears on your Articles of Organization and past annual reports.
- The current registered office address on file. The form asks for the old and the new address side by side.
- The current registered agent’s name, even if the agent is not changing.
- The full new street address, including any street number or rural route and box number. The new office must be in Illinois.2Illinois General Assembly. Illinois Code 805 ILCS 180/1-36 – Change of Registered Office or Registered Agent
- If you are switching agents, the new agent’s full legal name.
Filling Out the Statement of Change
The form is the Statement of Change of Registered Agent and/or Registered Office, tied to Sections 1-36 and 1-37 of the Illinois Limited Liability Company Act. It is available on the Secretary of State’s Business Services page.
Put the LLC’s legal name and file number at the top. Use the checkboxes to mark whether you are changing the agent, the office, or both. Enter the current agent and office information, then the new information. The statement has to confirm that after the change, the registered agent’s business address and the registered office address will be identical.2Illinois General Assembly. Illinois Code 805 ILCS 180/1-36 – Change of Registered Office or Registered Agent
A member or manager of the LLC has to sign. In a manager-managed LLC, that is a manager. In a member-managed LLC, an authorized member signs. The Secretary of State will not process an unsigned form or one signed by someone without authority.
How to File and What It Costs
Online
Filing through the Secretary of State’s online business services portal is the quickest option. You enter the information, pay by credit or debit card, and submit electronically. A small processing surcharge applies on top of the filing fee when you pay online.
By Mail
You can also print the completed form and mail it with a check or money order to the Department of Business Services at the Howlett Building in Springfield. The statute requires the statement to be submitted in duplicate.2Illinois General Assembly. Illinois Code 805 ILCS 180/1-36 – Change of Registered Office or Registered Agent The office returns filings that are incomplete, illegible, or underpaid without processing them.
The Fee
The Statement of Change filing fee has been the subject of recent legislative activity in the 104th General Assembly, so check the current fee schedule on the Secretary of State’s website before you send payment. Expedited processing is available for an added charge under a separate expedited services fee schedule.
If the Principal Place of Business Moved
Articles of Amendment cover changes to information originally reported in your Articles of Organization, including the principal place of business required under Section 1-40 of the Limited Liability Company Act.3Illinois Secretary of State. LLC Articles of Amendment This is a separate form with a separate fee.
Owners who physically relocate the business often need both filings: the Statement of Change for the registered office and Articles of Amendment for the principal office. Filing just one leaves the other address wrong in the state’s records.
Confirm the Change Went Through
Online filers get an email confirmation once processing finishes. Mail filers get a stamped copy back. Standard mail processing takes several business days; expedited filings move faster. The change becomes legally effective the moment the Secretary of State files the statement.2Illinois General Assembly. Illinois Code 805 ILCS 180/1-36 – Change of Registered Office or Registered Agent
Search the Secretary of State’s business database for your LLC and confirm the new address appears correctly. Catching a typo now beats catching it after a legal notice goes to the wrong place.
Update the IRS and the Illinois Department of Revenue
The Secretary of State does not notify tax agencies for you. Handle each one separately.
IRS
File IRS Form 8822-B to report a new business mailing address, business location, or both. There is no hard deadline for a plain address change, but delay carries a real cost: if the IRS mails a deficiency notice to your old address and you never see it, the window to contest it can close before you know it exists.4Internal Revenue Service. Form 8822, Change of Address If you are also changing the LLC’s responsible party, Form 8822-B has to be filed within 60 days of that change.5Internal Revenue Service. About Form 8822-B, Change of Address or Responsible Party – Business
Illinois Department of Revenue
Update the state through MyTax Illinois, by calling 217-785-3707, or by emailing REV.CRD@illinois.gov.6Illinois Department of Revenue. Updating Your Business Information If the LLC files state income tax, sales tax, or withholding tax returns, this is what keeps notices, correspondence, and refunds arriving at the right place.
What Happens If You Skip the Update
Letting the registered office address go stale creates real legal exposure, not just paperwork mess.
The first risk is missing a lawsuit. If someone sues the LLC and papers are delivered to the old registered office, a court can still find service proper even though nobody at your company saw them. That leads to a default judgment, and the plaintiff can then pursue your business bank accounts to collect.
The Secretary of State can also administratively dissolve an LLC that fails to maintain a registered agent in Illinois.7Illinois General Assembly. Illinois Code 805 ILCS 180/35-25 – Grounds for Administrative Dissolution An unreachable agent gives the state grounds to act. Dissolution strips the LLC of its authority to do business and can jeopardize the liability protection that motivated forming the LLC in the first place. Reinstatement takes more filings, back fees, and time.
On the tax side, the IRS and the Illinois Department of Revenue keep assessing penalties and interest on any balance owed regardless of whether their notices reach you. By the time you find out, a manageable bill can be a much larger one.
Other Records to Update
Once the state and tax filings are done, work through the rest of your records:
- Amend the operating agreement to reflect the new registered office and principal place of business, so internal governance documents match the state’s records.
- Check business licenses and permits. Many local licenses are tied to a specific address; ask your city or county clerk whether the new location needs a new license or just an update.
- Update business bank accounts, credit lines, and merchant services. Banks sometimes freeze accounts that show address mismatches during compliance reviews.
- Notify your commercial insurance carrier. A new zip code can move premiums up or down based on local claim history, and telling the carrier promptly avoids a coverage gap after an incident.
- File a USPS change of address to catch anything still going to the old location during the transition.
