If you’re in business in Los Angeles, you need to be aware of the legal ramifications of your operations. Knowing when you need to apply for an Employer Identification Number (EIN) is one key part of this process. An EIN is required of all businesses that have employees, as well as corporations and limited liability companies (LLCs)—but what else do you need to know? We’ve made this comprehensive guide to help you understand the process for applying for an EIN.

It's important for businesses to know that an Employer Identification Number (EIN) is not the same as a tax identification number (TIN). While the two terms are sometimes used interchangeably, they are conceptually distinct. An EIN is an identification number assigned to a business by the Internal Revenue Service (IRS) for tax filing purposes, whereas a TIN refers to any government-issued identification number for the purpose of paying taxes. For the remainder of this article, we will use the term EIN when discussing government issued identification numbers.
