What is an EIN Confirmation Letter?

EIN Confirmation Letter, also known as IRS Form SS-4, is an official confirmation of the assignment of an Employer Identification Number (EIN) to a company in the United States.

An EIN is a unique tax number assigned by the Internal Revenue Service (IRS) that identifies a company for tax, banking, and legal purposes.

EIN confirmation is required immediately after company registration, as the number is required for:

  • opening bank accounts;

  • filing tax returns;

  • hiring employees;

  • concluding contracts with customers and suppliers;

  • obtaining licenses and permits. p>


Main purpose

The document confirms:

  • that the company is officially registered with the IRS;

  • the assigned Employer Identification Number (EIN);

  • the date the number was issued;

  • the name and address of the registered company.

Without EIN Confirmation, the company will not be able to legally conduct financial activities in the United States.


Who issues the document

The IRS (Internal Revenue Service) — the US government tax authority — issues EIN Confirmation:

  • in paper form by mail;

  • electronically immediately after submitting Form SS-4 online.

Crystal Tax helps clients:

  • apply for an EIN;

  • obtain an EIN confirmation letter from the IRS;

  • prepare documents for banks, investors, and official procedures.


Document content

EIN confirmation usually includes:

  • the full name of the company;

  • legal address and state of registration (Delaware, USA);

  • assigned Employer Identification Number (EIN);

  • date of assignment of the number;

  • IRS contact details;

  • IRS signature and stamp.

The document can be in English. If necessary, Crystal Tax provides notarized translation and apostille for international use.


Validity and use

EIN confirmation does not expire, but banks, investors, and government agencies may require a recent copy for current transactions.
When changing your company's address or tax status, it is recommended that you notify the IRS and obtain an updated confirmation if necessary.


Why it is important to have an EIN Confirmation Letter

Without EIN confirmation, a company faces:

  • banks refusing to open accounts;

  • the inability to enter into legally binding contracts;

  • problems with tax reporting and compliance;

  • difficulties in international activities and attracting investment.
