What is an EIN?#

An Employer Identification Number (EIN) is a unique identifier issued by the IRS to businesses, trusts, estates, and other entities for tax reporting. Think of it as a “social security number” for your business. You may need an EIN to:

• File business tax returns (e.g., Form 1040 Schedule C for sole proprietors, Form 1120 for corporations).
• Open a business bank account.
• Hire employees (required for payroll tax filings).
• Apply for business licenses or loans.

EINs are free to obtain via the IRS website, mail, or fax, and they never expire. However, if your business closes or stops operating, you’ll need to formally notify the IRS to avoid unnecessary tax-related communication.

When Should You Deactivate Your EIN?#

Deactivating an EIN is not always required, but it’s critical in specific scenarios. Here are the most common reasons to deactivate your EIN:

1. Your Business Has Permanently Closed#

If you’ve shut down your business (e.g., dissolved a corporation, ended a partnership, or stopped operating as a sole proprietor), you should deactivate your EIN. This tells the IRS your business is no longer active and prevents future tax notices (e.g., reminders to file returns).

2. Your Business Structure Changed (And the EIN is No Longer Needed)#

If you restructure your business (e.g., a sole proprietor becomes an LLC, or a partnership merges into a corporation), you may need a new EIN. In this case, deactivate the old EIN associated with the previous structure.

3. You Never Used the EIN#

If you applied for an EIN but never used it (e.g., you abandoned your business idea or never opened a bank account), deactivate it. The IRS may still send notices if the EIN is listed as active but unused.

4. The Business Was Sold or Transferred#

If you sell your business to a new owner, the new owner must apply for their own EIN. You should deactivate your EIN to avoid being linked to the new owner’s tax liabilities.

Steps to Deactivate Your EIN with the IRS#

The IRS does not offer an online portal for EIN deactivation. Instead, you must notify them via mail (or fax for exempt organizations). Follow these steps to ensure your deactivation is processed correctly:

Step 1: Confirm You’re Eligible to Deactivate#

Before deactivating, ensure:

• Your business has no outstanding tax liabilities (e.g., unpaid taxes, unfiled returns). The IRS will not deactivate your EIN until all taxes are paid and all required returns are filed.
• You’ve filed all required final tax returns (mark the return as “final” if applicable). For example, a sole proprietor should file a final Schedule C, and a corporation should file a final Form 1120.

Step 2: Gather Required Information#

You’ll need the following details for your cancellation request:

• Your business’s legal name (as registered with the IRS).
• Your EIN (found on your EIN assignment letter or previous tax returns).
• Business address (as listed on your EIN application).
• Reason for deactivation (e.g., “business closed,” “structure changed,” “never used”).
• Contact information (name, phone number, email) in case the IRS needs to follow up.
• EIN assignment notice (if available — a copy of the letter the IRS sent when assigning your EIN).

Step 3: Write and Submit a Deactivation Letter#

Draft a formal letter to the IRS explaining your request. Include all the details listed above. Mail the letter to one of the IRS addresses listed below (or fax to 855-214-7520 for exempt organizations).

Note: The IRS provides two addresses for EIN deactivation requests:

• Internal Revenue Service, MS 6055, Kansas City, MO 64108
• Internal Revenue Service, MS 6273, Ogden, UT 84201

For closing a business account in general, you can also send to: Internal Revenue Service, Cincinnati, OH 45999.

Subject: Request to Deactivate Employer Identification Number (EIN) and Close Business Account – [Your EIN]

Dear Sir/Madam:

I am writing to formally request the deactivation of the Employer Identification Number (EIN) assigned to [Your Business Legal Name] and the closure of the associated IRS business account. The EIN in question is [9-digit EIN, e.g., XX-XXXXXXX].

The reason for this deactivation is [select one: “the business has permanently closed,” “the business structure has changed, and a new EIN has been obtained,” “the EIN was never used for business operations,” or specify other reason].

To confirm:

• The business has no outstanding tax liabilities. All required tax returns have been filed, including a final return marked “FINAL” where applicable.

Note: Send your letter to one of the following IRS addresses:

• Internal Revenue Service, MS 6055, Kansas City, MO 64108
• Internal Revenue Service, MS 6273, Ogden, UT 84201

For general business account closure, you can also send to: Internal Revenue Service, Cincinnati, OH 45999.

If you need to find the address based on your last filed tax return, check the instructions for that return. For example:

• Sole proprietors (Schedule C filers): Use the address where you filed your Form 1040.
• Corporations (Form 1120 filers): Use the address listed in the Form 1120 instructions.

Common Mistakes to Avoid#

Deactivating an EIN seems straightforward, but errors can lead to delays or IRS notices. Avoid these mistakes:

1. Not Filing Final Tax Returns#

Always file a final tax return and mark it as “FINAL” before deactivating your EIN. The IRS will not process your deactivation request if returns are missing or taxes are unpaid.

2. Sending the Letter to the Wrong IRS Office#

Mailing your deactivation letter to the wrong IRS center will delay processing. Use one of the official IRS addresses: Kansas City, MO 64108; Ogden, UT 84201; or Cincinnati, OH 45999.

3. Providing Incomplete Information#

Omitting your EIN, business name, or reason for deactivation can stall your request. Triple-check the letter for accuracy and include your EIN assignment notice if available.

4. Canceling an EIN for an Active Business#

Never request EIN deactivation if your business is still operating. This could lead to penalties or loss of access to business accounts.

5. Forgetting to Notify Banks or Creditors#

After deactivating your EIN, update your business bank account, loans, and vendors with your new EIN (if applicable) or notify them of the closure.

FAQ About EIN Deactivation#

Q: Can I reuse a deactivated EIN?#

A: No. Once an EIN is assigned to a business entity, it becomes that entity’s permanent federal taxpayer ID number. Even after deactivation, the EIN cannot be reused. If you start a new business, you’ll need to apply for a new EIN.

Q: How long does it take the IRS to process an EIN deactivation?#

A: Processing times vary, but you can generally expect the IRS to process your deactivation request within 4–8 weeks. The IRS may send a written confirmation letter, but this is not guaranteed. If you don’t receive confirmation within 8 weeks, you can call the IRS Business & Specialty Tax Line at 800-829-4933 to check the status.

Q: What if I have unpaid taxes?#

A: You must pay all outstanding taxes and file any missing returns before your EIN can be deactivated. The IRS will not process the deactivation until your account is current.

Q: Do I need to deactivate an EIN for a dormant business?#

A: If your business is inactive but not permanently closed (e.g., you’re taking a break), you do not need to deactivate the EIN. Only deactivate if the business will never operate again.

Q: Can I deactivate an EIN online?#

A: No. The IRS does not offer an online deactivation tool. You must submit a letter via mail. Exempt organizations may fax their request to 855-214-7520.
