What Is CP 575?

CP 575 is an essential document issued by the IRS to businesses and organizations that apply for an EIN.1 The CP 575 serves as proof of the assigned EIN and includes important details about the entity, such as its legal name, address, and the type of organization it represents.

Why Is CP 575 Important?

Here are some rock-solid reasons why the CP 575 and the EIN combo is an absolute must-have for businesses like yours: 

Identification: The CP 575 provides a unique identifier for businesses, much like a Social Security Number does for individuals. 

Taxation: The EIN, represented by the CP 575, allows businesses to report and pay taxes, including income tax, employment tax, and excise tax. It ensures compliance with federal tax regulations and facilitates proper filing and tracking of tax returns. 

Business Banking: Banks often require an EIN to open a business account. The CP 575 serves as proof of the assigned EIN, enabling smooth banking transactions and separation of personal and business finances.

How Does CP 575 Work?

The CP 575 is a form issued by the IRS that confirms the EIN of a business. Businesses that are just starting out will receive their CP 575 when they apply for an EIN via IRS Form SS-4, which provides all the necessary information about the business, including its name, address, and type of ownership. The application process can be completed online and is usually quick and easy. 

Once approved, the CP 575 is sent electronically to the business owner and can be used immediately. Businesses can then take advantage of all the benefits that come with having a CP 575 form.

What Are The Benefits Of CP 575?

Having an EIN and a CP 575 form can help businesses in many ways. Let's take a closer look at some of the most prominent benefits: 

1. Legal Compliance: Obtaining an EIN through CP 575 ensures compliance with federal tax laws and regulations, avoiding potential penalties and legal issues. 

2. Credibility: Having a unique EIN adds credibility and professionalism to a business, as it provides an official identifier recognized by the IRS and other government agencies. 

3. Separation Of Finances: With an EIN and a dedicated business bank account, business owners can separate personal and business finances, making accounting and financial management more organized and transparent. 

4. Employee Management: An EIN obtained via CP 575 is necessary for businesses with employees, enabling proper tax withholding and reporting and facilitating employee payroll processes.

Are There Any Downsides To CP 575?

While the CP 575 and EIN combination is a great way for businesses to get started, it has some downsides. 

  1. The CP 575 does not protect businesses from fraudulent activity like identity theft or cyber-attacks. Businesses should use other measures to ensure their online security and privacy. 

  2. Business owners are responsible for submitting accurate information when they apply. If the information needs to be corrected, it could lead to costly errors and delays in filing taxes or opening a bank account.

  3. The CP 575 is only valid within the US - businesses operating in foreign countries must obtain a different EIN.

What Are The Alternatives To CP 575?

CP 575 is the most reliable way of confirming a business's EIN. However, if you misplace it and need an original paper document to confirm your EIN, you can request an EIN Verification Letter 147c from the IRS.2 This will provide you with an official letter that confirms the assigned EIN and other details about your business. A copy of this letter may be used as proof of your EIN.
