Which LLC Changes Need a New EIN?
4 of the 11 common LLC change events need a new EIN, and all 4 involve a change in ownership or a new entity formed under state law. The other 7, including the name change, keep the same number.
One rule explains every row below. The IRS ties an EIN to an entity and to the federal classification that entity carries. Change the label and the file stays open. Change how many people own the LLC and the IRS sees a different taxpayer, with a different annual return, on a different form.
| Change event | New EIN? | What the IRS wants instead |
|---|---|---|
| The LLC changes its legal name | No | State amendment, then written notice to the IRS |
| The LLC changes its business address | No | Form 8822-B, filed within 60 days |
| The LLC adds a second or third location | No | Nothing. One EIN covers every location |
| The LLC changes its responsible party | No | Form 8822-B, filed within 60 days |
| The LLC starts a second line of business | No | Nothing. One EIN covers every activity |
| An LLC with an EIN elects corporate status | No | Form 8832, effective date on line 8 |
| An LLC with an EIN elects S corporation status | No | Form 2553, due 2 months and 15 days in |
| A single-member LLC takes on a second member | Yes | New Form SS-4 for the new partnership |
| A multi-member LLC drops to a single owner | Yes | New Form SS-4 for the surviving owner |
| A new LLC is formed in another state to replace this one | Yes | New Form SS-4 for the new entity |
| A single-member LLC is newly formed and elects corporate status | Yes | New Form SS-4 for the new entity |

Two more triggers written into the calendar
The IRS attaches 2 dated conditions to newly formed single-member LLCs. A new single-member LLC needs its own EIN when it has an excise tax filing requirement for tax periods beginning on or after January 1, 2008, or an employment tax filing requirement for wages paid on or after January 1, 2009. Both dates sit in the past, so both conditions apply to every LLC formed today that hires or files excise tax.

How Do You Notify the IRS of an LLC Name Change?
By 1 of 3 routes, chosen by your federal classification: box 3 on line G of Form 1065, box 3 on line E of Form 1120, or a signed letter to the IRS. Each route costs $0.
The state amendment comes first. The IRS records the name your state approved, so a notification sent before the amendment is stamped goes into the file against a name that does not legally exist. Order the 2 steps correctly and the update is 1 signature long.
| Federal classification | Where the new name is reported | Line and box | Who signs |
|---|---|---|---|
| Partnership, 2 or more members | Form 1065, page 1 | Line G, box 3 | A partner or member-manager |
| Corporation, after Form 8832 | Form 1120, page 1 | Line E, box 3 | A corporate officer |
| S corporation, after Form 2553 | Form 1120-S, page 1 | Line H, box 2 | A corporate officer |
| Disregarded single-member LLC | Signed letter to the IRS | No box exists | The owner |
| No return filed yet | Signed letter to the IRS | No box exists | The owner |

What the letter route has to carry
A disregarded single-member LLC has no name-change box, because it files no entity return of its own. The letter carries 5 items: the EIN, the former legal name, the new legal name, the LLC address, and a signature from a person authorized to act for the company. A copy of the state-stamped amendment goes with it. Send it to the IRS campus where the LLC files its return.
The classification decides the route, and the classification was set on Form SS-4 lines 8a, 8b and 9a when the EIN was issued. If you have never confirmed which of the 3 boxes your LLC sits in, read LLC tax classification before writing anything.
Does Adding a Member to an LLC Change the EIN?
Yes. A single-member LLC that takes on a second member becomes a partnership under federal law, files Form 1065 each year, and needs a new EIN. Dropping from 2 members to 1 needs a new EIN as well.
This is the mechanism people miss, because nothing visible changes. The Articles keep the same name, the bank keeps the same account, and the sign on the door is untouched. Under federal law, though, a disregarded entity and a partnership are 2 different taxpayers filing 2 different returns.
1 member becomes 2. The disregarded entity ends and a partnership begins. Form 1065 replaces Schedule C, and a fresh Form SS-4 is filed with line 8b set to 2.
2 members become 1. The partnership ends when 1 owner takes over the business. The surviving owner files a new Form SS-4 for the entity that continues.
A member sells to a new member. The count stays at 2, so the partnership survives and the EIN survives with it. Ownership percentages change on Schedule K-1, not on Form SS-4.
A member is added and the name changes on the same day. The member count wins. A new EIN is issued, and the new legal name goes on line 1 of the new Form SS-4.
Line 8b of Form SS-4 is where this decision lands, and it is the single field einforllc.co checks on every order. Read EIN for a single-member LLC and EIN for a multi-member LLC for the 2 sides of it.
Do Forms 8832 and 2553 Change an LLC EIN?
No. An LLC that already holds an EIN keeps the same 9-digit number through a Form 8832 corporate election and a Form 2553 S corporation election. Only the annual return changes, from Form 1065 to Form 1120-S.
An election changes the tax treatment of an existing entity. It does not create a new one. The EIN sits in the identification block of both forms, which is proof in itself that the IRS expects the number to already exist before either election is filed.
Form 8832, line 8. The effective date sits no more than 75 days before the filing date and no more than 12 months after it.
Form 8832, the 60-month rule. An LLC that elects a classification waits 60 months before electing again, so the first election is the one that counts.
Form 2553. Due within 2 months and 15 days of the start of the tax year the S corporation election takes effect.
The number itself. Unchanged through both. The same EIN moves from Form 1065 to Form 1120-S with no application in between.
One exception sits at the front end. A brand new single-member LLC that elects corporate status at formation needs an EIN of its own, because there is no prior number to carry forward. The full election mechanics live on form 8832 llc.
Does Moving an LLC to a New State Change the EIN?
No, when the same LLC moves. An LLC that domesticates or registers as a foreign LLC keeps 1 EIN and reports the new address on Form 8822-B within 60 days. Forming a replacement LLC creates a new entity.
Two routes carry the same name in conversation and produce opposite answers at the IRS. The test is whether the original entity survives the move.
| Move route | Does the entity survive? | EIN | What you file |
|---|---|---|---|
| Domestication or conversion | Yes, 1 entity throughout | Same EIN | Form 8822-B within 60 days |
| Foreign qualification in a 2nd state | Yes, 1 entity in 2 states | Same EIN | State registration only |
| Dissolve, then form a new LLC | No, 2 separate entities | New EIN | A new Form SS-4 |
| Merge into a newly formed LLC | No, the survivor is new | New EIN | A new Form SS-4 |
Source: IRS Publication 1635, verified July 2026. State procedures vary by state.
A move between states leaves the EIN alone because the entity does not change. The IRS assigns the number federally, and no part of it encodes the state of formation, so an LLC that redomesticates from Delaware to Wyoming carries the same 9 digits into the new charter.
What does change is the state layer. The LLC registers with the new state, obtains a new state taxpayer number, appoints a registered agent there, and files a final report in the old state. Form 8822-B updates the IRS address record within 60 days, and that is the entire federal obligation.
One route does force a new number. Dissolving the LLC in the old state and forming a fresh LLC in the new one creates a different entity, and the new company applies on its own Form SS-4. Redomestication and dissolution look similar in outcome and differ completely in paperwork.
What Happens When an LLC Changes Its Responsible Party?
The LLC files Form 8822-B within 60 days and keeps the same EIN. The responsible party is the individual who controls the LLC and its funds, named on Form SS-4 line 7a. It is never a company.
This is the change most owners never report, and it is the one with a fixed clock on it. The IRS mails every notice about the EIN to the responsible party on file, so an out-of-date name is how a compliance letter goes to someone who left the business 2 years ago.
Form 8822-B covers 3 changes. A new business mailing address, a new business location, and a new responsible party. One form, $0, no EIN impact.
The 60-day clock. It runs from the date of the change, not from the date you notice it. Filing 1 form inside 60 days closes the obligation.
Line 7a takes a human being. A parent LLC, a formation agent, or a registered agent on line 7a triggers rejection. The IRS wants the person with control.
Line 7b takes Foreign. An incoming responsible party without an SSN enters Foreign on line 7b, exactly as at the original filing.
Which LLC Documents Must Match the New Name?
4 documents: the state amendment, the IRS record behind the EIN, the bank file, and every payment processor account. Banks verify the legal name against an IRS letter, and the IRS never reprints the CP-575.
The CP-575 is issued once per EIN, at the moment the number is assigned, carrying the name the LLC held that day. After a name change that document is a historical record. The replacement confirmation, and the one banks accept, is the 147C letter, which the IRS issues at $0 on request and prints with the current name on file.
State-stamped amendment. The source document. Every other update is checked against the legal name the state approved, character for character.
The IRS name on file. Updated by the return box or the signed letter. It is the name that prints on the next 147C letter.
Bank and fintech records. Mercury, Wise, Relay, Chase and Bank of America each re-verify the legal name against an IRS letter before updating an account.
Payment processors. Stripe, PayPal and Amazon match the EIN and the legal name against IRS records, so a stale name fails the check.
The 147C is requested from the IRS Business and Specialty Tax Line at 800-829-4933, open Monday to Friday, 7 a.m. to 7 p.m. local time, and the IRS releases it only to an authorized person. Read LLC CP-575 letter for what banks check line by line, or lost LLC EIN if the original letter is already gone.
What Are the Deadlines After an LLC Name Change?
One hard federal deadline exists: 60 days for Form 8822-B. The name notification rides with the next annual return or goes by letter immediately. A foreign-owned LLC still faces the $25,000 Form 5472 penalty.
| Action | Form or route | Deadline | Federal cost |
|---|---|---|---|
| Amend the LLC name | State amendment article | Set by the state | State fee |
| Tell the IRS the new name | Form 1065, 1120 or 1120-S box | With the next annual return | $0 |
| Tell the IRS the new name now | Signed letter to the IRS campus | Any time after the amendment | $0 |
| Report a new address | Form 8822-B | Within 60 days | $0 |
| Report a new responsible party | Form 8822-B | Within 60 days | $0 |
| Refresh the EIN confirmation | 147C letter request | On request, by phone | $0 |
| File the annual partnership return | Form 1065 | Annually | $0 to file |
| File the foreign-owner return | Form 5472 + pro-forma 1120 | Annually | $25,000 if missed |
Source: IRS Form 8822-B instructions and Internal Revenue Code section 6038A, verified July 2026.
The $25,000 figure is the one foreign owners hit first. A foreign-owned single-member LLC files Form 5472 with a pro-forma Form 1120 every year, even with $0 of income, and the return goes in under the EIN with the current legal name. A name change updated at the state but never reported to the IRS puts a mismatch on a return that carries a $25,000 penalty. Read Form 5472 and EIN for a foreign-owned LLC.
What Does an LLC Name Change Cost at the IRS?
$0. The IRS charges nothing to record a new LLC name, nothing for Form 8822-B, and nothing for a 147C letter. When a change does force a new EIN, the IRS fee for that number is also $0.
The only federal money question on this page is what a new EIN costs when the member count changes and the LLC genuinely needs one. Filing it yourself is free in every channel. Paid services exist because the no-SSN route runs on paper, and the table below is the honest comparison.
The costs that do attach to a name change sit at the state level, not the federal one. Amending the Articles of Organization runs roughly $50 to $200 depending on the state, and a new registered agent appointment or an amended annual report carries its own fee. None of that money reaches the IRS.
Replacing the paperwork afterwards is also free. The CP-575 prints 1 time and is never reissued, but the 147C verification letter carrying the same 9 digits and the updated legal name costs $0 on a call to 800-829-4933. An LLC can request it as many times as it needs.

What Does a Paid Filing Add When a Change Forces a New EIN?
A second reader on the 2 fields that decide the application: the new legal name on line 1 and the member count on line 8b. Both have to match the amended Articles, and either one wrong sends the application back by mail weeks later.
What the $97 buys when a change forces a new number
The new EIN has to be filed against the new legal name, character for character, with the member count on line 8b matching the ownership that triggered the change. That is 2 fields, and getting either one wrong sends the application back weeks later by mail. einforllc.co reviews the amended Articles, sets lines 8a, 8b and 9a, and files to 855-641-6935 or 855-215-1627 within 1 business day. On Standard the SS-4 is filed by fax within 7 business days, or that fee is refunded, and the EIN and CP-575 land 16–19 business days out. On Fast at $127 the filing and the IRS call happen within 24 hours, guaranteed, or that fee is refunded, and the whole run takes 6 to 8 business days. Business days are Monday to Friday excluding US federal holidays. Year 2 and every year after costs $0 for the EIN, because an EIN never renews.
