You’ve spent months building a brand. Maybe the old name just doesn’t fit anymore, or you’ve pivoted from selling handmade candles to offering full-scale interior design. Whatever the reason, you’re ready to rebrand. But then it hits you: the taxman. Dealing with an IRS change of business name sounds like a bureaucratic nightmare involving endless hold music and cryptic forms.
Honestly? It’s not that bad if you know which "bucket" your business falls into.
The IRS doesn't have one single "Change My Name" button. Instead, how you notify them depends entirely on how your business is structured. If you're a sole proprietor, you're looking at a different process than a massive C-Corp. People mess this up constantly by thinking they need a brand-new Employer Identification Number (EIN). Usually, you don’t. Getting a new EIN when you don't need one can actually create a massive headache with your tax history.

How to Handle Your Entity Type
Let's get into the weeds.
If you are a Sole Proprietorship, the IRS basically sees you and the business as the same person. You don't have a formal "entity" name in the eyes of the federal government in the same way a corporation does. To change things, you just write a letter. That’s it. You sign it, you send it to the address where you file your returns, and you tell them, "Hey, I’m changing my name from 'Dave’s Dogs' to 'Dave’s Deluxe Dining'." Just make sure an authorized person signs it. If it's just you, well, you're the authorized person.
Corporations have it a bit tougher.
If you’re running a C-Corp or an S-Corp, you report the name change on your next income tax return. If you are filing Form 1120, there’s a little checkbox on Page 1, Line E, Number 3. For S-Corps filing 1120-S, it’s Page 1, Line H, Number 2. You check that box, and you’re basically telling the IRS, "New name, same us."
But what if you already filed your taxes for the year and you can’t wait until next April? You can't just sit around. In that case, you write a letter to the IRS. It needs to be signed by a corporate officer. Don't forget to include your EIN and the new name.
Partnerships and LLCs
Partnerships (Form 1065) follow a similar vibe to corporations. There’s a checkbox on the front of the return. If you’ve already filed, you’re back to the "letter-writing" method.
Now, LLCs are the wild card.
The IRS doesn’t actually recognize an "LLC" as a tax classification. You’re either a "disregarded entity" (taxed like a sole prop), a partnership, or a corporation. You have to follow the rules for whatever way you choose to be taxed. If you're a single-member LLC that files a Schedule C with your 1040, you follow the sole proprietor rules. Write the letter.

The EIN Question: Do You Need a New One?
This is where people spiral.
"Do I need a new EIN for an IRS change of business name?"
Usually, no.
A name change is a cosmetic fix. You only need a new EIN if the "soul" of the business changes—like if you go from a sole proprietorship to a partnership, or if you incorporate. If you’re just changing "Blue Widget LLC" to "Red Widget LLC," your EIN stays exactly the same.
Think of your EIN like a Social Security Number. If you get married and change your last name, you don't get a new SSN. Same logic here. If you accidentally apply for a new EIN, you’ll end up with two active accounts at the IRS for the same business. That is a fast track to getting a confusing "failure to file" notice because the IRS expects a tax return for both numbers. It’s a mess. Don't do it unless you are actually changing your legal structure.
Don't Forget the Secretary of State
The IRS is actually the second step.
Before you even talk to the feds, you have to talk to your state. Most states require you to file "Articles of Amendment." You pay a fee—usually between $20 and $150 depending on if you live in a place like Kentucky or California—and wait for them to approve it.
The IRS will often want to see that state approval. If you send a letter to the IRS saying your name is now "Quantum Leap Tech" but your state records still say "Leap Frog Consulting," the IRS might kick it back or just ignore it. Keep your ducks in a row.
The "DBA" Trap
Some people don't actually change their legal name. They just use a "Doing Business As" (DBA) name.

If your legal name is "John Doe Services" but you want to put "The Marketing Guru" on your website, that’s a trade name. You usually don't even need to tell the IRS about a DBA unless you want that name to appear on your official tax transcripts. Most of the time, the IRS only cares about the legal name associated with the EIN. Your bank, however, will care a lot. They’ll want to see the DBA registration before they let you cash a check made out to the trade name.
Why Speed Matters
You might think, "I'll just wait until tax season."
Bad move.
If you change your name in July but wait until April to tell the IRS, your payroll taxes might get wonky. If you file Form 941 (payroll) under a name that doesn't match the IRS records for your EIN, their system might flag it. It creates a mismatch. Mismatches lead to notices. Notices lead to stress.
Just send the letter.
Real World Example: The "Signed Letter"
Let's say you're Sarah. You run Sarah's Books LLC as a single-member LLC. You want to change it to "Nova Editorial LLC."
- Sarah files Articles of Amendment with her Secretary of State.
- Once she gets the stamped approval back, she writes a simple letter.
- The letter says: "To whom it may concern, I am writing to notify you of an IRS change of business name. My EIN is XX-XXXXXXX. The old name was Sarah's Books LLC. The new name is Nova Editorial LLC. Attached is the state approval."
- She signs it as "Sarah Smith, Owner/Member."
- She sends it via Certified Mail. (Always use Certified Mail with the IRS. Always.)
Where to Send the News
The IRS is divided into regions. You don't just send your name change to "The IRS, Washington D.C." You send it to the service center where you file your tax returns.
If you’re in the Northeast, it’s probably Ogden, UT or Cincinnati, OH, depending on the form. Check the instructions for your specific tax form (like the 1040 or 1120) to find the correct mailing address. It changes occasionally, so looking at the most recent "Where to File" chart on IRS.gov is the only way to be 100% sure you aren't sending your sensitive info to a building that’s been closed for three years.
Common Myths About Name Changes
People love to spread bad advice on Reddit.
One common myth is that you can just call the IRS and change your name over the phone. You can't. They need a "signature of an authorized person." An IRS agent can't verify your signature over a phone call. They are obsessed with paper trails.
Another one? "You have to close your business and restart it."
Absolute nonsense. That would mean losing your business credit history, your bank accounts, and your tenure with vendors. A name change is a transition, not a death.
Actionable Next Steps
If you are ready to pull the trigger on an IRS change of business name, here is your immediate checklist. Forget the fluff; just do these things in order:
- File with your State first: Get your Articles of Amendment approved. You cannot skip this.
- Check your tax structure: Confirm if you are a Corporation, Partnership, or Sole Prop/Disregarded Entity.
- Draft the IRS letter: If you aren't waiting for your next tax return, write the notification letter. Include your EIN, old name, new name, and a copy of the state's approval.
- Mail it Certified: Go to the post office. Pay for the green "Return Receipt Requested" card. It is the only proof you have that they received it if they lose it later.
- Update your Bank: Once the state approves the name, go to your bank immediately. They will likely need the state amendment and potentially a copy of the letter you sent to the IRS.
- Update your licenses: Professional licenses, health permits, or liquor licenses need to reflect the new name too. These agencies often communicate with the state, but rarely with the IRS.
- Notify your vendors: Your 1099s at the end of the year need to match your new name so your accounting doesn't become a nightmare.
Changing a business name is a bit like moving houses. It's a lot of small tasks that feel overwhelming, but as long as you notify the right people in the right order, you won't get lost in the shuffle. Just keep your EIN steady and keep your paperwork organized.
