Let’s get started!

What Is A CP 575

CP 575, also referred to as IRS CP 575, refers to a confirmation letter issued by the Internal Revenue Services in the United States confirming a company’s Employer Identification Number (or EIN).

Companies in the United States are required, in most cases, to have an EIN number allowing the US authorities, particularly the IRS, to deal with the business entity.

A company’s EIN number is the equivalent of an individual’s Social Security Number.

Why Do You Need An IRS CP-575

When you operate a business in the US, in most cases you will need to get an Employer Identification Number (EIN) representing a unique number assigned to your company by the IRS.

You will need your EIN to perform many types of transactions or business operations, such as:

  • To file your company taxes
  • To open a commercial bank account
  • To apply for a business credit card
  • To register your employees for payroll

In some cases, you will be asked to confirm your EIN number and that will take care of business for you.

However, in other cases, you will be asked to provide evidence or proof that the EIN you are using was in fact officially issued to your company.

If you need to prove that the IRS has issued an EIN to your company, you will then need to show your IRS letter CP 575.

Content of Form CP 575

The content of IRS forms CP 575 is pretty simple.

The IRS form CP 575 contains:

  • Your company name 
  • Your company’s address 
  • The company’s new EIN number (a nine-digit number)
  • Information about certain forms the company will have to file (such as Form 940, Form 941, and Form 1120)

The form CP 575 IRS is a short document that is generally a one-pager (or perhaps two pages) where your EIN is confirmed.

How To Get A Copy of CP 575

Many of you wonder: How do I get a copy of my CP 575?

For the IRS to issue a CP-575 letter to a company, a request for a new EIN must be made.

Typically, you will need to apply for a new EIN but completing and filing an IRS Form SS-4 entitled “Application for Employer Identification Number”.

This form can be found on the IRS website.

When an EIN applicationhttps://www.irs.gov/businesses/small-businesses-self-employed/apply-for-an-employer-identification-number-ein-online is sent to the IRS, they will review the application and eventually approve it if all the information provided checks out.

Following their approval, you will receive the IRS CP 575 letter in the mail.

Misplaced CP 575 IRS

If you had received an IRS 575 and misplaced it, you should keep in mind that the IRS will not provide you with another one.

When your Form 575 is lost, you will need to ask for an EIN Verification Letter 147C (also called a 147C Letter).

The 147C letter is another IRS document that officially confirms your EIN number and you’ll be able to use it in lieu of the IRS CP 575 form.

To get a 147C letter, you should:

  • Call the IRS Business and Specialty Tax Line at 1-800-829-4933 (or 267-941-1099 if you are calling from outside of the US)
  • Press 1
  • Press 1 again
  • Press 3
  • Request a 147C letter
  • Answer the IRS representative questions 

Then, they will send you an IRS 147 C so you can replace your lost or misplaced CP-575 IRS form.

CP 575 Form Takeaways 

So there you have it folks!

What is a 575 form given by the IRS?

How does the IRS notice CP 575 work?

In essence, an IRS form 575 is an official document issued by the IRS confirming a company’s EIN representing a unique identification number issued to companies in the United States.

In other words, the CP 575 letter confirms that the IRS has granted your company an EIN.

The IRS will mail this letter to the address the company will provide on line 4 of the SS-4 application form.

Keep in mind that the CP575 letter is only sent by mail in physical copy, it will not be emailed or faxed by the IRS.

Generally, you should receive it within eight to ten weeks following the submission of your SS-4 application.

If you lose your 575CP letter, you will not be able to replace it with another but can get a 147C letter officially confirming the EIN issued to your company by the IRS.
