Tips – Federal ID Number
What is an EIN?
An Employer Identification Number (EIN), also known as a Federal Tax Identification Number, is a nine-digit number that the IRS assigns to business entities. The IRS uses this number to identify taxpayers that are required to file various business tax returns. EINs are used by employers, sole proprietors, corporations, partnerships, non-profit organizations, trusts and estates, government agencies, certain individuals and other business entities.
Determine If You Need a Federal ID Number
If you’re a sole proprietor (no employees) and are not incorporated, you probably don’t need a separate Federal ID Number (FEIN), but if you’re incorporated or have employees, you do. You can download the form from the IRS Web site. See “Where To File” below.
If you become the new owner of an existing business, do not use the EIN of the former owner. If you already have an EIN, use that number. If you do not have an EIN, apply for one on this form. If you become the “owner” of a corporation by acquiring its stock, use the corporation’s EIN.
Changes in Organization or Ownership
If you already have an EIN, you may need to get a new one if either the organization or ownership of your business changes. If you incorporate a sole proprietorship or form a partnership , you must get a new EIN. However, do not apply for a new EIN if:
- You change only the name of your business, or
- You elected on Form 8832, Entity Classification Election, to change the way the entity is taxed.
If you are electing to be an “S corporation,” be sure you file Form 2553, Election by a Small Business Corporation. File only one Form SS-4, regardless of the number of businesses operated or trade names under which a business operates. However, each corporation in an affiliated group must file a separate application .
Caution: An EIN is for use in connection with your business activities only. Do NOT use your EIN in place of your Social Security Number (SSN).
