The Internal Revenue Service issues employers a Tax ID for their business. The Business Tax ID is also known as an Employer I.D. Number, or EIN. Businesses, local or state government agencies, and Non-Profit organizations have to apply for an EIN for IRS tax purposes. EINs are used by the IRS, the government, and other companies, agencies, and systems, to identify the entity. Employer ID Numbers (EIN/Tax ID) are located on the tax return forms you file every year.
If you have obtained an EIN (Tax ID Number) from the IRS in the past, but do not remember your Business Tax ID, you can call the IRS EIN Department directly at 1-800-829-4933 to speak with an IRS EIN representative. The Managing Member of the EIN needs to be the one to call, and you will need to verify your information and your social security number with the IRS EIN representative. Once this is done, you will also be able to request the IRS EIN Department to fax you a copy of your EIN Letter.
