Which of the following is NOT a reason for a business to obtain an EIN?

Obtaining an Employer Identification Number (EIN) is an essential process for businesses in various scenarios, primarily for tax purposes. The correct answer highlights that filing personal taxes is not a reason for a business to acquire an EIN.

Businesses need an EIN when they hire employees because it allows the Internal Revenue Service (IRS) to track payroll taxes for those employees. This number is also crucial for opening a business bank account, as banks typically require an EIN to ensure compliance with federal regulations and to differentiate between personal and business finances.

When it comes to applying for a business license, local and state regulations often require an EIN to complete the application, as it signifies the business's registered status with the IRS for tax purposes.

In contrast, filing personal taxes pertains to individual tax returns and does not involve business-specific tax identification requirements. Therefore, businesses do not need an EIN for this personal tax filing process, making the option of “filing personal taxes” the correct distinction from the other provided reasons.
