How long does it usually take to receive the EIN after faxing in Form SS-4, and will the EIN be provided by fax or only by mail? - North Carolina

Short Answer

For a North Carolina estate, the EIN is issued by the IRS, not by the Clerk of Superior Court. If Form SS-4 is faxed and includes a return fax number, the IRS generally sends the EIN back by fax within about four business days; the official confirmation letter usually follows by mail. If no return fax number is provided, the EIN generally arrives by mail, which can take several weeks.

Understanding the Problem

This question asks whether a third-party designee handling a North Carolina probate matter can expect an estate EIN after faxing Form SS-4, how long that usually takes, and whether the number comes by fax or only by mail. The key issue is the IRS delivery method after the online EIN application fails and the estate must use a paper Form SS-4.

Apply the Law

An estate EIN is a federal taxpayer identification number used to identify the estate for banks, income-producing assets, and required filings. In North Carolina probate, the personal representative handles estate administration under the supervision of the Clerk of Superior Court, but the IRS controls EIN issuance. A third-party designee may help obtain the EIN only if Form SS-4 properly authorizes that person and the form is signed by the fiduciary with authority for the estate.

When a paper Form SS-4 is faxed, the IRS instructions generally allow a faster response than mail. The practical trigger is whether the faxed SS-4 includes a valid return fax number and the IRS can process the application without needing more information.

Key Requirements

  • Proper estate applicant: The application should identify the estate, not the deceased person individually, and should use the estate’s correct legal name and responsible party information.
  • Authorized signer and designee: The personal representative or other fiduciary should sign Form SS-4. A third-party designee can receive the EIN only if the designee section is completed and authorized.
  • Return fax number: To receive the EIN by fax, the fax submission should include a working return fax number. Without that, the IRS generally sends the EIN by mail.
  • IRS processing review: If the form is incomplete, inconsistent, hard to read, or flagged after an online reference code, the IRS may require a call or additional information before issuing the EIN.

What the Statutes Say

Analysis

Apply the Rule to the Facts: The online application could not be completed and returned a reference code, so the next practical step is a paper Form SS-4. Because the applicant is acting as a third-party designee, the form should be signed by the estate’s personal representative or other fiduciary and should clearly authorize the designee. If the faxed SS-4 includes a return fax number and the IRS does not need more information, the EIN usually comes back by fax within about four business days, with the verification letter later arriving by mail.

In a North Carolina probate file, the estate EIN is commonly needed before opening an estate bank account or moving income-producing estate assets into the estate’s name. For more background on this related step, see this overview on how to get an estate tax ID number.

Process & Timing

  1. Who files: The personal representative, fiduciary, or authorized third-party designee. Where: Fax Form SS-4 to the IRS fax number listed in the current IRS instructions; North Carolina probate itself remains with the Clerk of Superior Court in the county estate file. What: IRS Form SS-4, Application for Employer Identification Number. When: After the online EIN application fails or cannot be completed; the fax response is typically about four business days if a return fax number is provided.
  2. The IRS reviews the SS-4. If the form is complete and authorization is clear, the IRS generally sends the EIN to the return fax number. If something is missing or inconsistent, the IRS may delay processing or require the responsible party to call.
  3. The estate should keep the faxed EIN confirmation with the probate file and estate banking records. The IRS verification letter, often called the EIN confirmation letter, usually follows by mail and should also be saved.

Exceptions & Pitfalls

  • No return fax number: If the SS-4 does not include a return fax number, the IRS generally will not fax the EIN and will send the response by mail instead.
  • Online reference code: A prior online error or reference code may mean the IRS needs to verify information. The responsible party may need to call if the IRS will not discuss the issue with the designee.
  • Designee authorization problems: A third-party designee should not assume authority. The designee section must be completed, and the proper estate representative should sign the form.
  • Wrong applicant name: Using the deceased person’s individual name instead of the estate’s name can create banking and record problems. The estate’s EIN should match the estate identity used for administration.
  • Mail delays: The mailed confirmation letter can arrive after the faxed EIN. The faxed EIN can usually be used for estate administration tasks while the mailed letter is pending, but banks may have their own documentation rules.
  • Tax filing questions: An EIN does not answer whether the estate must file any federal or North Carolina return. Those questions should be reviewed with a CPA or tax attorney.

Conclusion

After faxing Form SS-4 for a North Carolina estate, the EIN usually arrives by fax within about four business days if the form includes a working return fax number and the IRS can process it without more information. The mailed verification letter usually follows later. If the online application produced a reference code, the next step is to fax a complete, signed SS-4 with third-party designee authorization and a return fax number.
