How to Change an LLC Name in Illinois

For Limited Liability Companies (LLCs) registered in Illinois, changing your business name requires amending your Articles of Organization. This is a formal process managed by the Illinois Secretary of State. You must first ensure that your desired new business name is available for use in Illinois. You can perform a business name search on the Illinois Secretary of State's website to confirm availability. Once you've confirmed the name is unique and available, you'll need to file an Amendment t

Changing Your Corporation's Name in Illinois

For corporations formed in Illinois, the process of changing a business name mirrors that of an LLC in that it requires filing an amendment with the Illinois Secretary of State. Specifically, you will need to file an Amendment to the Articles of Incorporation. This document officially records the change in your corporation's legal identity. Before filing, similar to an LLC, you must verify that the proposed new corporate name is available for use in Illinois by conducting a search on the Secreta

Updating a DBA (Assumed Name) in Illinois

If you are operating a sole proprietorship, partnership, or even an LLC or corporation under an assumed name (DBA) in Illinois, the process for changing that DBA name is different from changing the legal entity name. In Illinois, a DBA is registered with the county clerk where the business is located, not with the state Secretary of State, unless the DBA is used by a corporation or LLC. For sole proprietorships and general partnerships, you will need to file a new "Assumed Business Name" certifi

IRS Notification and Federal Tax ID (EIN)

When you change your business name in Illinois, understanding the implications for your federal tax identification, particularly your Employer Identification Number (EIN), is crucial. For most business structures, including LLCs and Corporations, if the change is only in the business name and not in the ownership or structure of the entity, your EIN generally remains the same. The IRS assigns an EIN to the entity itself, not to its name. Therefore, you typically do not need to apply for a new EI

Updating Other Agencies and Business Records

Beyond the Illinois Secretary of State and the IRS, a business name change necessitates updating numerous other agencies and internal records to ensure legal compliance and smooth operations. This includes state and local licensing boards, tax agencies, and any other government bodies where your business is registered or holds permits. For example, if your business requires specific industry licenses or permits in Illinois – such as those for food service, construction, or professional services

Reasons to Change Your Business Name

There are several strategic and operational reasons why a business might decide to change its name. One common driver is rebranding. A company might evolve beyond its original mission, expand into new markets, or simply want to modernize its image to appeal to a broader audience or a different demographic. A name that once resonated might feel dated or no longer accurately reflect the business's current offerings or values. A fresh name can signal a new direction and reinvigorate customer intere

Frequently Asked Questions

How long does it take to change a business name in Illinois?
Processing times for name changes in Illinois can vary. Filing an amendment with the Secretary of State typically takes a few business days to a couple of weeks, depending on their workload. Expedited services may be available for an additional fee. DBA name changes at the county level can often be processed more quickly, sometimes within a few days.
Do I need to file a new DBA if I change my LLC's legal name?
If your LLC's legal name is changing, and you were using that same name as your DBA, then you do not need to file a new DBA. The state filing of the amendment to your Articles of Organization effectively changes both. However, if your LLC operates under a legal name AND a separate DBA, and you only want to change the DBA, you would file a new DBA certificate with the county clerk.
What is the fee to change a business name in Illinois?
The filing fee to amend the Articles of Organization or Incorporation with the Illinois Secretary of State is typically around $100. DBA filing fees vary by county, usually ranging from $10 to $50. Always check the official Illinois Secretary of State website and your specific county clerk's office for the most current fee information.
Can I use my old business name after changing it?
No, once your business name change is officially approved and filed with the Illinois Secretary of State, you must cease using the old name for business purposes. Your legal entity is now known by the new name. Continuing to use the old name could lead to confusion or legal issues. All operations, marketing, and communications should immediately transition to the new name.
Do I need a new EIN if I change my business name in Illinois?
Generally, no. If only your business name changes and the ownership and structure of your entity remain the same, your Employer Identification Number (EIN) issued by the IRS stays the same. You must, however, notify the IRS of the name change through your tax return or a formal letter.
