Changing your company name in the United States is a formal legal process, not just a branding decision. You must file Articles of Amendment with your state’s Secretary of State and notify the IRS to stay compliant. Here is a clear overview of the full process:
Core steps at a glance:
- Get internal approval from shareholders or members.
- Check name availability with your state’s Secretary of State.

How to file Articles of Amendment with your state
Filing Articles of Amendment is the official legal step to change your company name. Every state has its own form and process, but the general sequence is consistent across the country.
Steps to complete the state filing:
- Check name availability. Use your state Secretary of State’s online database to confirm the new name is not already taken. You must check name availability in every state where your business operates.
- Run a trademark search. Search the USPTO’s Trademark Electronic Search System (TESS) to confirm the name is not federally trademarked by another party.
- Get internal approval. Corporations need a shareholder resolution. LLCs need documented member consent, typically recorded in meeting minutes.
- Complete the Articles of Amendment form. Download the correct form from your Secretary of State’s website and fill it out accurately.
- Submit and pay the filing fee. Fees range from $25 to $150 depending on the state. Some states offer expedited processing for an additional fee.
Processing times vary widely. Standard filing can take days to several weeks, depending on the state and submission method.
Pro Tip: Before finalizing your new name, check for domain availability and existing social media handles. A legally available name that is already claimed online creates unnecessary friction during rebranding.
How to notify the IRS after a company name change
The IRS must know about your name change to keep your federal tax records accurate. The notification method depends on your business structure and filing status.
- If you have not yet filed your return, mark the “name change” box on your federal tax form. Form 1065 covers partnerships; Form 1120 covers corporations.
- If you have already filed, send a signed letter to the IRS office where you file your return. Include your old name, new name, EIN, and the effective date of the change.
- Sole proprietors report the name change on Schedule C of Form 1040.
A critical point that many business owners miss: a name change alone does not require a new Employer Identification Number. The IRS confirms that an EIN stays the same as long as the entity type and ownership structure remain unchanged.
IRS guidance: “If you change your business name, you do not need to apply for a new EIN unless you also change your business structure or ownership.” Notify the IRS promptly to avoid mismatches on future tax filings.
Delays in updating federal records can cause rejected filings or payment processing errors. Act within the same tax year as the name change whenever possible.
Is a DBA a better option than a full legal name change?
A DBA, short for Doing Business As, lets a business operate under a different name without changing its legal registration. This is a practical alternative for owners who want a new public-facing name but prefer to keep the existing legal entity intact.
When a DBA makes sense:
- You want a shorter or more marketable trade name.
- You are launching a new product line under a different brand.
- The cost and complexity of a full legal name change outweigh the benefit.
DBA vs. legal name change at a glance:
| Factor | DBA Registration | Legal Name Change |
|---|---|---|
| Filing level | County or state | State Secretary of State |
| Cost | Generally lower | Varies by state filing fee |
| Legal identity | Unchanged | Officially updated |
| Trademark protection | Not provided | Possible with USPTO filing |
| IRS notification | Not required | Required |
A DBA registration allows branding flexibility, but it does not grant trademark rights. Anyone else can use the same trade name in another jurisdiction. For full legal protection, a formal name change combined with a federal trademark application is the stronger path.
Costs, timelines, and practical steps after the name change
State filing fees for a legal name change vary by state, with expedited options available in many cases for faster processing. Plan for a total timeline of two to six weeks from filing to final approval, depending on your state’s workload and submission method.
Once the state approves the name change, the operational work begins.
Key updates to complete after approval:
- Bank accounts and financial institutions. Bring your filed Articles of Amendment to your bank. Update all accounts and notify lenders, payment processors, and credit card providers.
- Business licenses and permits. Contact every state and local agency that issued your licenses. Operating under an old name on active permits creates compliance risk.
- Contracts and legal documents. Review all active contracts and update them with the new legal name. Many business owners overlook registered agent records, which can create legal disputes later.
- Vendors and customers. Send formal written notice to all vendors and clients. Keep a message on your old website, email signatures, and social profiles for 30–60 days post-change to reduce customer confusion.
For brand consistency across digital channels, update your website, Google Business Profile, and all social media accounts on the same day the change goes live.
Pro Tip: Prepare a master checklist of every account, license, and contract that carries your company name. Work through it systematically rather than reactively. Missing even one vendor record can create payment delays or legal complications.
