An IRS business name change usually updates the name attached to your existing EIN, not the EIN itself. The IRS accepts a business name change through a tax-return checkbox or a signed letter, not through an online name-change tool.

Key Takeaways
- A legal name change alone usually does not require a new EIN.
- There is no dedicated IRS business name change form.
- Form 8822-B updates a business address, location, or responsible party, not the business name.
- Corporations, S corporations, and partnerships can use the name-change checkbox on their next business return.
- Sole proprietors and many single-member LLCs use a signed letter to the IRS.
- Update the state record first, then the IRS, then banks, payroll, licenses, contracts, and W-9s.
IRS Business Name Change: The Short Answer
If the only thing changing is your legal business name, you normally keep the same EIN. The Employer Identification Number identifies the taxpayer entity. It does not change just because the entity adopts a new legal name.
The IRS record still needs to be updated. Your federal tax filings, W-9s, payroll records, bank onboarding, and 1099 reporting all rely on a matching name and EIN. If the IRS still has the old name while your bank or customer uses the new one, automated checks can fail.
You have two practical paths. If your business files a federal entity return, you may be able to check the name-change box on the next return. If you already filed, do not file a business return with a name-change box, or need the update sooner, mail a signed name-change letter to the IRS.
Do not apply for a new EIN just to match the new name. An unnecessary second EIN can split tax records across two accounts and create more cleanup work than the original name change.
Form 8822-B Is Not a Name Change Form
Many business owners search for an IRS business name change Form 8822 or Form 8822-B PDF. That search leads to the wrong result. The IRS has no standalone form for changing a business name.
Form 8822-B is titled Change of Address or Responsible Party - Business. It is used to tell the IRS about a new business mailing address, a new business location, or a new responsible party. It does not have a field for a new legal business name, so filing it by itself will not update the name on your EIN record.
Form 8822 is also not the answer. It is for individual address changes, not business legal names.
Use Form 8822-B only if the name change happens at the same time as an address change or responsible-party change. In that situation, the form handles those separate updates, while the business name change still happens through the return checkbox or a signed letter. If you need to change a responsible party, check the IRS's current instructions because that update has its own reporting rules.
Change Business Name on EIN by Entity Type
The IRS method depends on how your business is taxed. LLCs follow their federal tax classification, not just the letters LLC in the name. A single-member LLC taxed as a disregarded entity uses the owner-letter route. A multi-member LLC taxed as a partnership follows the partnership route. An LLC taxed as a corporation follows the corporate route.
| Business type | Return checkbox option | Letter option | Who signs the letter |
|---|---|---|---|
| Sole proprietorship | No business return checkbox | Use a signed letter | Owner or authorized representative |
| Single-member LLC taxed as disregarded | No separate entity return checkbox | Use a signed letter | Owner or authorized representative |
| C corporation | Form 1120, page 1, Item E, box 3 | Use if the return was already filed or timing requires it | Corporate officer |
| S corporation | Form 1120-S, page 1, Item H, box 2 | Use if the return was already filed or timing requires it | Corporate officer |
| Partnership or multi-member LLC | Form 1065, page 1, Item G, box 3 | Use if the return was already filed or timing requires it | Partner |
When using the return method, enter the new legal name in the name block and check the name-change box. When using the letter method, send the request to the IRS address where the business files its return. Because IRS service center addresses can change, confirm the current address in the applicable IRS where-to-file instructions before mailing.
IRS Name Change Letter vs Online Options
There is no EIN name change online option on the IRS website. The online EIN Assistant issues new EINs. It does not edit an existing EIN record, change a business name on EIN, or change EIN information online.
If you are not using the tax-return checkbox, prepare a signed letter. The letter does not have to follow an official IRS template, but it should be complete enough for the IRS to identify the account and confirm the authorized request.
Include the date, the old legal name exactly as it appears in IRS records, the new legal name exactly as approved by the state, the EIN, the business mailing address on file, and the effective date of the legal name change. Ask the IRS to update its records and send written confirmation. The letter should be signed by the owner, a partner, or a corporate officer, and should show that person's printed name and title.
Use company letterhead if you have it. Attach a copy of the approved state amendment when the entity is registered with a state. The IRS may not always require the attachment, but it helps connect the requested IRS update to the legal name the state approved.
Mail the letter with tracking and keep a copy. Until the IRS record updates, your mailing receipt is the best evidence that you sent the request.
Do You Need a New EIN?
A business name change by itself does not create a new taxpayer. The same legal entity continues to own the EIN. The IRS's new EIN guidance focuses on changes in ownership or structure, not ordinary renames.
You may need a new EIN when the legal or tax identity changes. Examples include a sole proprietorship incorporating, a sole proprietorship taking on partners and operating as a partnership, a partnership incorporating, one partner taking over a partnership and operating it as a sole proprietorship, or a statutory merger that creates a new entity. A corporation can also need a new EIN when it receives a new state charter or changes into a partnership or sole proprietorship.
Be careful with entity conversions. If an LLC changes only its legal name, the EIN usually stays. If the transaction creates a new entity under state law or changes the tax classification in a way that requires a new taxpayer account, the result can be different. Check the IRS's current EIN guidance and get tax advice before filing if the name change is part of a merger, acquisition, conversion, or ownership change.
Correct Order: State, IRS, Bank, Payroll, W-9s
Start with the state. The IRS records your legal business name, but the state creates or amends that legal name for an LLC, corporation, or other registered entity. File the articles of amendment, certificate of amendment, or your state's equivalent with the Secretary of State or other filing office before telling the IRS.
After the state approves the amendment, notify the IRS using the checkbox or letter method. Use the exact name approved by the state, including punctuation, entity ending, and spacing. Small differences can cause mismatch problems later.
Then update the institutions that rely on the name and EIN pair. Banks and lenders often ask for the state-stamped amendment and IRS proof. Payroll providers need the correct name for payroll tax filings. State tax agencies may require their own update. Licenses, permits, insurance policies, leases, vendor accounts, and contracts may also need amendments or written notices.
Finally, give customers and other payers a new W-9. If they file 1099s under your new name while the IRS still has the old name, the name and EIN may not match. If timing is tight, ask whether they need the name currently on IRS records for tax reporting until the update posts.
If the rename is tied to an entity conversion, trademark concern, or multi-state filings, a business attorney can keep the state amendments, IRS notice, bank records, contracts, and customer notices consistent. You can post your legal need on UpCounsel's marketplace and typically receive responses within a day from attorneys who can file amendments, correct mismatched records, and paper the transition.
Confirm the IRS Updated Your Business Name
IRS name changes take time. Plan for several weeks of processing, and longer during busy filing periods or if the IRS needs more information. Do not assume the update is complete just because you mailed the letter or checked the box on a return.
The best confirmation is written IRS proof showing the new name and EIN. The IRS can provide an EIN verification letter, commonly called a 147C letter, after it verifies that the caller is authorized for the business. You can request it through the IRS Business & Specialty Tax Line at 800-829-4933 during the line's business hours.
A 147C letter is different from the original EIN confirmation notice. The original notice is issued when the EIN is assigned and is not reissued as a new original. The 147C shows the name and EIN currently in IRS records, so it is useful for banks, payroll providers, lenders, and other parties that need proof of the updated IRS record.
If the letter still shows the old name after a reasonable processing window, confirm whether the IRS received your request and resend it if needed.
Legal Name Change vs. DBA or Rebrand
A legal name change is different from a DBA or marketing rebrand. A legal name change amends the official name of the entity in state records. That is the type of change the IRS needs to record for the EIN account.
A DBA, trade name, or assumed name lets the same business operate under another public-facing name while keeping its legal name. For example, a company can keep its LLC name in state and IRS records while using a different storefront name. Because the legal name has not changed, a DBA alone generally does not require an IRS business name change letter.
A rebrand can be even simpler. A new logo, website, product line, or marketing position does not affect the legal name unless you formally amend the entity record or register a DBA. Before starting IRS paperwork, ask one question: should the legal name on tax records change, or only the name customers see? If only the public-facing name changes, update branding materials and registrations as needed, but do not ask the IRS to change the EIN name.
Frequently Asked Questions
Do I have to notify the IRS of a business name change?
Yes, you should notify the IRS when the legal name attached to your EIN changes. The IRS uses that name to match tax returns, payroll filings, and information returns. If you do not update it, the mismatch can slow filings, confuse banks, and create problems for customers that report payments to your business.
How long does it take the IRS to change a business name?
It often takes several weeks for the IRS to process a business name change. Timing can vary based on filing season, mail volume, and whether the request was complete. Keep using the name that matches IRS records for tax filings until you have confirmation that the new name appears on the EIN account.
How do I confirm a business name change with the IRS?
You confirm a business name change by getting written IRS proof of the name currently attached to the EIN. After the processing window, an authorized person can call the IRS Business & Specialty Tax Line and request an EIN verification letter. If the letter shows the new legal name, the IRS record has updated.
Do I need a new EIN if I change the name of my company?
No, you usually do not need a new EIN if only the company name changes. A new EIN is tied to changes in ownership or structure, not a simple rename. If the name change is part of a merger, conversion, incorporation, or ownership transfer, check the IRS new-EIN rules before deciding.
Can I complete an EIN name change online?
No, you cannot complete an EIN name change online through the IRS. The IRS online EIN tool is for new EIN applications, not updates to existing EIN records. To update the name, use the applicable business return checkbox or mail a signed letter with the EIN, old name, new name, and authorized signature.
Is Form 8822-B the IRS business name change form?
No, Form 8822-B is not an IRS business name change form. It is used for a business address, location, or responsible-party update. If those details changed along with the name, you may need Form 8822-B too, but the name change still requires the return checkbox or signed letter process.
