Frequently Asked Questions About the National Standard Employer Identifier (EIN). How does an employer obtain an EIN?


The Internal Revenue Service maintains the process for assigning EINs. An employer obtains an EIN by submitting IRS Form SS-4, Application for Employer Identification Number, to the IRS. Any business that pays wages to one or more employees is required to have an EIN as its taxpayer identifying number. There would be few, if any, employers that would not already have an EIN for taxpayer identifying purposes.
