How to Cancel an EIN (2026) Guide
EINs cannot be cancelled. Once issued, an EIN is permanent. You close the IRS business account by letter, but the number stays assigned to your entity forever.
EINs cannot be cancelled. Once the IRS assigns a 9-digit EIN to your entity, that number stays tied to it forever. You can close the IRS business account by mailing a signed letter, but the number is never deleted, reused, or transferred. Starting a new business requires a new EIN. The IRS charges $0 to close an account and $0 to issue an EIN.
An EIN (Employer Identification Number) is the 9-digit federal tax ID the IRS assigns to a business entity. People search for "cancel EIN" when they dissolve an LLC, abandon an unused entity, or fix a duplicate registration. The IRS does not offer cancellation. It offers account closure. This page explains the difference, walks through the closing letter, lists every event that forces a new EIN, and shows non-residents how to file Form SS-4 for a fresh EIN without an SSN or ITIN.

The Rule
Why Can an EIN Never Be Cancelled?
An EIN can never be cancelled because the IRS designs it as a permanent federal taxpayer identification number. Once assigned, the number stays with that entity for the life of IRS records. You stop using it, but you never erase it.
The IRS states the rule plainly: once an EIN is assigned to a business entity, it becomes the permanent federal taxpayer identification number for that entity. The number is never reissued to a different entity. It is never recycled. This protects the integrity of every past tax return, payroll record, and information filing linked to that EIN.
This is why the correct action is closing the business account, not cancelling the number. Closing the account tells the IRS your entity has stopped operating. The EIN remains searchable in IRS systems forever.
| You Can Do This | You Cannot Do This |
|---|---|
| Close the IRS business account | Cancel or delete the EIN number |
| File a final tax return | Remove the EIN from IRS records |
| Dissolve the legal entity | Transfer the EIN to a new entity |
| Stop using the EIN | Reuse the EIN for a new business |
| Reactivate by filing later | Get a refund (no fee was charged) |

How Do You Close an EIN Business Account?

Attach the EIN Notice
Mail to the IRS and Dissolve at the State Level

New EIN
When Do You Need a New EIN?
You need a new EIN when you create a new legal entity, change the entity type, change the responsible owner, or enter bankruptcy. You do not need a new EIN for a name change or an address change. The old EIN cannot follow you to a new entity.
The table below covers the most common triggers. The IRS bases the rule on whether a new legal entity exists, not on cosmetic changes to an existing one.
| Event | New EIN Required? |
|---|---|
| Forming a brand-new entity | Yes |
| Converting a sole proprietorship to an LLC | Yes |
| New owner takes over a sole proprietorship | Yes |
| Corporation files for bankruptcy | Yes |
| Partnership becomes a corporation | Yes |
| LLC name change only | No |
| LLC address change only | No |
| Electing a new tax classification (same entity) | No |
If you closed an old account and now operate a new entity, apply fresh. Non-residents apply by filing Form SS-4 by fax. See how to get an EIN for the full process and multiple EIN numbers for entities that hold more than one.
For Non-Residents
How Does a Non-Resident Get a New EIN After Closing One?
A non-resident gets a new EIN by filing Form SS-4 by fax to 855-215-1627, using a passport number on Line 7b instead of an SSN. The IRS online tool requires an SSN, so non-residents use the fax method. Correctly filed EINs arrive in 4-7 business days.
A common scenario: a founder dissolves an old US LLC, closes its EIN account, then forms a new LLC for a new venture. The new entity needs its own EIN. The old EIN cannot transfer. Here is the path.

Cancel vs Close
What Is the Difference Between Cancelling and Closing an EIN?
Cancelling an EIN means deleting the number, which the IRS never does. Closing an EIN account means telling the IRS your entity stopped operating, which the IRS does accept by letter. The number survives in both common search phrases.
People use "cancel," "close," "deactivate," and "delete" interchangeably online. The IRS recognizes only account closure. The table separates the myth from the rule so you file the right paperwork.
| Term People Use | What the IRS Actually Does |
|---|---|
| "Cancel my EIN" | No action; EINs are not cancelled |
| "Delete my EIN" | No action; the number is permanent |
| "Close my EIN account" | Accepts a closing letter to Cincinnati, OH 45999 |
| "Deactivate my EIN" | Treats the account as dormant once final return is filed |
| "Reuse my EIN" | Never; a new entity needs a new EIN |
If your goal is simply to stop operating, file the final return and send the closing letter. If your goal is to open a US bank account or run a new company, you need an active EIN instead. See EIN for a bank account.
