CP 575 Letter

What Is a CP 575 Letter?

A CP 575 EIN Confirmation Letter is a document issued by the Internal Revenue Service (IRS) to confirm the unique Employer Identification Number (EIN) they have issued to a new business. An EIN is used by the IRS to identify a business for tax purposes, much like a Social Security number is used by the IRS to identify an individual.

What Is in a CP 575 Letter?

A CP 575 letter contains the new business’s EIN as well as information about tax forms that the business will be required to file.

How Do You Get a CP 575 Letter?

Before a CP 575 letter is issued, a new business must apply for an EIN by submitting IRS Form SS-4. Once the application has been approved, the IRS will mail a CP 575 letter within four to six weeks to the address the applicant listed on Form SS-4.

What Is a CP 575 Letter Used For?

The EIN provided in a CP 575 letter is required for such things as filing your company’s taxes, opening a business bank account, and applying for a business credit card, loan, or payroll processing. In many of these cases, all you need to provide is the number itself—but some organizations insist on seeing an original government document that proves the number is yours. That’s when your CP 575 letter is essential.

Can a CP 575 Letter Be Replaced?

The IRS will not replace a CP 575 letter. However, if you have misplaced it and you need an original paper document to confirm your EIN, you can request EIN Verification Letter 147C, another official IRS letter that can generally be used for all of the same purposes as a CP 575. To make this request, call the IRS at 1-800-829-4933.
