How to Cancel / Close an EIN with the IRS (2026)

You cannot delete an EIN — once the IRS assigns one, it exists in their system permanently. What you can do is close the associated IRS business account, which deactivates the EIN for future use. This guide covers exactly when you should close an EIN, the correct letter format to send the IRS, what happens to the number, and the critical difference between closing your EIN account and dissolving your LLC with the state.

Cancel close EIN with IRS — how to close business account for dissolved LLC step by step guide 2026
Quick Answer

To close an EIN, write a letter to the IRS requesting closure of your business account — include your LLC's legal name, EIN, business address, and reason for closing. Mail to: IRS, Cincinnati, OH 45999. If you have the original EIN confirmation letter (CP575), include it. The IRS processes closure requests in about 45 days and sends a confirmation. The EIN number itself is never truly deleted — it is deactivated and can never be reissued to another entity.

Can You Actually Cancel an EIN?

The first thing to understand about canceling an EIN is that the IRS never truly deletes an EIN. Once assigned, the nine-digit number is permanently associated with your entity in IRS records — it cannot be reassigned, reused, or erased. What you can do is request that the IRS close the business account associated with that EIN, which deactivates it for future use.

This distinction matters: if you ever need to reopen a business later, you would reactivate the same EIN — you would never receive a new one for the same entity. Likewise, if you sold your LLC, the buyer can use the same EIN (though some situations require a new one — covered below).

Terminology note. The IRS does not use the phrase "cancel EIN" in its official guidance — it calls the process "closing your business account" or "canceling your EIN." Both phrases refer to the same action: submitting a written request to deactivate the EIN account. This guide uses "cancel EIN" because that's how most people search for it, but the official IRS terminology is "close your business account."

Should You Cancel Your EIN? When It Makes Sense

Canceling an EIN is not mandatory — even after dissolving your LLC. The IRS does not require you to close a business account when a business ends. However, there are situations where requesting EIN closure is the right move:

You have permanently dissolved your LLC Primary Reason If your LLC has been legally dissolved with the state, filed all final tax returns, and has no remaining assets, liabilities, or obligations — closing the IRS account is a clean administrative step that formally ends the IRS relationship with the entity.
You received a duplicate EIN by mistake Common Error Some LLC owners accidentally apply for two EINs for the same entity — once online and once by phone, for example. Cancel the EIN you haven't used yet, keeping the one associated with your LLC's official records and bank account.
You never used the EIN and want to clean up records Recommended If you got an EIN for an LLC you never actually formed or used, closing the account prevents IRS confusion about unfiled returns — particularly if the IRS later sends notices expecting annual filings from the entity.
You are changing your business structure Situation Dependent Some structural changes (converting from a sole proprietorship to a corporation, or changing from a single-member to multi-member LLC that changes tax classification) require a new EIN. In these cases, you would cancel the old EIN and apply for a new one.

Do NOT cancel your EIN if you might restart the business. If there's any chance you will reactivate your LLC or use the same entity again, do not submit an EIN closure request. The same EIN can be reactivated simply by writing to the IRS or resuming business filings. Closing and later reopening is more work than simply leaving the account dormant. An unused EIN with no filing activity generates no fees or penalties on its own.

Complete These Steps Before Canceling Your EIN

The IRS will not accept an EIN cancellation request if you have outstanding tax obligations. Before sending your closure letter, verify every item below is complete. Attempting to cancel an EIN with unfiled returns or open balances results in the IRS rejecting your request and sending collection notices instead.

File your final federal tax return Required File your LLC's final tax return — Form 1065 (partnership), Form 1120-S (S-Corp), Form 1120 (C-Corp), or Schedule C (disregarded entity) — for the last year of operation. Check the "Final Return" box on the return. This signals to the IRS that no future returns are expected.
Pay all outstanding taxes, penalties, and interest Required Any unpaid federal tax balance — including payroll taxes, income taxes, or accumulated penalties — must be settled before the IRS will close your account. Outstanding balances survive EIN cancellation and remain collectible from the LLC's responsible parties.
File final payroll returns if you had employees Required if applicable File your final Form 941 (quarterly payroll tax), Form 940 (annual federal unemployment), and W-2s for all employees. Check the "Final Return" box on each. Deposit any remaining payroll tax liabilities before filing.
Dissolve the LLC with your state Required — separate from IRS Canceling your EIN with the IRS does not dissolve your LLC in your state. You must separately file Articles of Dissolution (or equivalent) with your state's Secretary of State office, pay any final annual report fees, and formally wind up the business. Both steps are required — they are completely independent processes.
Close your business bank account Recommended Close the LLC's business bank account and distribute remaining funds to members before or simultaneously with LLC dissolution. Banks cannot process transactions for a dissolved entity, and leaving an account open under a dissolved LLC's name creates liability and banking compliance issues.
Cancel business licenses and permits Recommended Cancel any state or local business licenses, sales tax permits, and professional licenses associated with the LLC. Many states auto-assess fees for licenses not formally cancelled, even if the LLC is dissolved.

EIN Cancellation vs LLC Dissolution — Two Completely Separate Processes

This is the most important distinction most LLC owners miss. Canceling your EIN with the IRS and dissolving your LLC with your state are two independent, unrelated actions. One does not automatically trigger the other. Both must be completed separately.

IRS Action
Cancel / Close Your EIN Business Account
  • Submitted by written letter to IRS Cincinnati, OH
  • Deactivates the EIN in federal tax records
  • Signals no future federal returns expected
  • Does NOT dissolve your LLC legally
  • Does NOT cancel state registrations
  • Does NOT relieve pre-existing tax debt
  • ~45 days processing by mail
State Action
Dissolve / Wind Up Your LLC
  • Filed with your state's Secretary of State office
  • Articles of Dissolution or Certificate of Termination
  • Ends the LLC's legal existence in that state
  • Removes obligation to pay future annual report fees
  • Does NOT close your IRS business account
  • Does NOT cancel your EIN automatically
  • State-specific fees and processing times apply

Which to do first — state or IRS? File your state dissolution first. The IRS may request your state dissolution documents as supporting evidence when reviewing an EIN cancellation request. Having the state confirmation in hand makes your IRS letter stronger. The typical order: (1) file final state returns → (2) file Articles of Dissolution with the state → (3) receive state dissolution confirmation → (4) send EIN cancellation letter to IRS.

How to Cancel an EIN: Step-by-Step

There is no official IRS form for closing an EIN business account. The IRS requires a written letter — mailed to their Cincinnati processing center. The letter must include specific information; missing any of it results in rejection and delay.

  1. Complete all pre-closure requirements above. File your final tax return with "Final Return" checked, pay all outstanding balances, close payroll accounts, and dissolve the LLC with your state before writing this letter. The IRS verifies your filing history before processing closures. Do not send the closure letter until final returns are filed and all taxes are paid.
  2. Write your EIN cancellation letter using the template below. The IRS requires: LLC legal name, EIN, business address, reason for closure, a statement that you have filed all final returns, and a request to close the account. If you have your original EIN confirmation letter (CP575), include a copy — it helps the IRS locate your account faster.
  3. Sign the letter as an authorized representative of the LLC. The letter must be signed by a member, manager, or authorized officer of the LLC. It cannot be submitted anonymously. Include your title (e.g., "Managing Member") beneath your signature.
  4. Mail the letter to the IRS at the correct address. Mail to: Internal Revenue Service, Cincinnati, OH 45999. Send via USPS certified mail with return receipt so you have proof of delivery and the date the IRS received it. Keep the tracking confirmation and return receipt permanently. The IRS does not accept EIN cancellation requests by fax, email, or phone — mail only.
  5. Wait approximately 45 days for IRS confirmation. The IRS sends a written confirmation letter confirming the business account has been closed. This letter is your permanent proof that the EIN account is deactivated. File it with your LLC's dissolution documents. If you don't receive confirmation within 60 days, call the IRS Business & Specialty Tax Line at (800) 829-4933 to follow up.

When You Need a New EIN Instead of Canceling

Not every business change calls for canceling your EIN. In some situations, you need a new EIN rather than closing the old one. Here's how to know which applies:

Situation Action Required Explanation
LLC permanently dissolved Cancel EIN Close the account after filing final returns. If you start a new business, get a new EIN for the new entity.
Duplicate EIN obtained in error Cancel duplicate Keep the EIN associated with your official records; cancel the unused one.
LLC name change only Keep same EIN A name change does not require a new EIN. Notify IRS of the name change via written letter or Form SS-4 amendment.
Address or ownership % change Keep same EIN These changes don't affect the EIN. Update IRS records by writing a letter or updating your annual return.
Single-member LLC adds a second member Keep same EIN Tax classification changes from disregarded entity to partnership, but the EIN remains the same.
LLC elects S-Corp or C-Corp status Keep same EIN Tax elections do not require a new EIN. File Form 2553 or 8832 using the existing EIN.
LLC purchased by new owner (stock/membership purchase) Keep same EIN When ownership transfers but the LLC entity continues, the EIN stays with the entity.
LLC purchased via asset purchase (not entity) New EIN needed Buyer forms a new entity to hold the assets; that new entity needs its own EIN. Old LLC cancels its EIN.
Sole proprietor incorporating into LLC New EIN needed A new LLC is a new legal entity — it needs its own EIN even if the owner is the same person.

What Happens After You Cancel an EIN

After the IRS processes your EIN cancellation request and sends your confirmation letter, several things happen — and some important things do not happen that you might assume.

What Does Happen

  • The IRS marks the business account as closed in their system
  • The EIN is deactivated — it cannot be used to file new returns or open new accounts
  • The IRS sends a written confirmation letter to the address in your closure letter
  • The IRS stops expecting future annual returns under that EIN
  • You receive confirmation you can store permanently with your dissolution records

What Does NOT Happen

  • The EIN is not deleted — it remains in IRS records permanently, just deactivated
  • Prior tax years are not affected — the closure is forward-looking only
  • Outstanding tax debts do not disappear — any remaining balances are still owed
  • Your LLC is not dissolved by the IRS — state dissolution must be done separately
  • Your state registrations are not cancelled — annual report obligations continue until state dissolution is complete
  • The number cannot be reissued — that EIN is permanently yours and will never belong to another entity

Ahmad Adil's Take: Most LLC owners who are closing a business underestimate how many steps are involved and how separate the IRS and state processes are. I've seen people dissolve their LLC with the state and assume everything is done — then get IRS notices two years later asking why Form 1065 wasn't filed. The "Final Return" checkbox on your last tax return and the written EIN closure letter are what tell the IRS you're done. Do both, send the letter certified mail, and keep the confirmation forever. The whole process takes maybe 90 minutes of actual work — most of the timeline is just waiting for the IRS to mail back their confirmation.

Frequently Asked Questions

Cancel / Close an EIN — FAQ

Can I cancel or delete my EIN?
You cannot delete an EIN — the IRS never removes an EIN from their system. Once assigned, the number is permanent. What you can do is request the IRS close your business account associated with the EIN, which deactivates it for future use. The EIN remains in IRS records indefinitely but can never be reassigned to another entity. Submit a written closure letter to the IRS at Cincinnati, OH 45999.
Is there a form to cancel an EIN?
No — the IRS does not have a dedicated form for closing an EIN business account. The process requires a written letter that includes your LLC's legal name, EIN, business address, and reason for closure, along with confirmation that all final tax returns have been filed and all taxes paid. Use the template in this guide as your starting point. Mail it certified to the IRS at Cincinnati, OH 45999. There is no online, fax, or phone option for EIN cancellation.
How long does it take the IRS to cancel an EIN?
The IRS typically processes EIN cancellation requests in approximately 45 days. Processing times vary based on current IRS workload. The IRS sends a written confirmation letter to the address in your closure request. If you do not receive confirmation within 60 days, call the IRS Business & Specialty Tax Line at (800) 829-4933 with your EIN and the date you mailed the letter to follow up.
Does canceling my EIN dissolve my LLC?
No. Canceling your EIN with the IRS and dissolving your LLC with your state are completely separate, independent processes. Canceling your EIN only closes your federal tax account — it has no effect on your state LLC registration, annual report obligations, or legal existence. To fully shut down your LLC, you must also file Articles of Dissolution (or the equivalent) with your state's Secretary of State office and pay any final state fees or taxes owed.
Do I need to cancel my EIN if I dissolved my LLC?
It is not legally required, but it is strongly recommended. Without a formal EIN closure, the IRS may continue expecting annual tax returns from the entity and send notices or even penalty assessments when those returns are not received. Marking your final tax return as "Final Return" is the minimum — sending the EIN closure letter is the complete solution that formally ends the IRS's expectation of future filings. If you might restart the business or reuse the LLC, leave the EIN active (deactivated EINs can be reactivated).
Can I reactivate a cancelled EIN later?
Yes. Because the EIN is never truly deleted, it can be reactivated. To reactivate a closed EIN, write a letter to the IRS explaining that you are resuming business operations under the same entity and requesting reactivation of the account. You can also simply resume filing tax returns under the EIN — the IRS will reactivate it automatically when a return is received. If too much time has passed, the IRS may ask you to call (800) 829-4933 to confirm the reactivation.
What if I never used my EIN and want to cancel it?
If you obtained an EIN but never used it and never operated a business under that entity, you can still request closure. Your cancellation letter should state: "The EIN was obtained but the entity was never activated and no business activity occurred. No tax returns were filed. I am requesting closure of this account." This is simpler than a dissolution closure because there are no final returns to reference. Include your original CP575 confirmation letter if you have it to help the IRS locate the account.
