What is an EIN?

EIN stands for Employer Identification Number, but it’s a bit of a misnomer. It’s really just a tax ID number, like a social security number, for a business. Whether the business has employees or not, it may still be required to get an EIN; even if not required, it’s highly recommended to have one.

Does my business need an EIN?

The short answer is yes. The longer answer is that it’s legally required for all businesses other than sole proprietorships. However, even for sole proprietorships, it’s highly recommended to get an EIN. Otherwise you would have to use your personal social security number on various forms and documents, which is not a good idea.
