CP 575 Letter

What is CP 575 Letter?

The CP 575 letter is an official document issued by the Internal Revenue Service (IRS) to confirm the unique Employer Identification Number (EIN) assigned to a new business. Much like a Social Security number identifies an individual, the EIN serves as a federal tax identifier for the business.

Why CP 575 Letter Matters

Businesses typically need the CP 575 letter when opening bank accounts, applying for licences, filing tax returns, or establishing credit. Since the IRS only issues this letter once, it is important for HR and finance teams to store the original securely. If the letter is lost, a business can request a 147C verification letter as a replacement.
