Form SS-4 & Employer Identification Number (EIN)
Question: Under what circumstances am I required to change my employer identification number (EIN)?

- A sole proprietorship changes to a corporation or a partnership.
- A sole proprietorship files for bankruptcy under Chapter 7 (liquidation) or Chapter 11 (reorganization).
- A sole proprietorship establishes a pension, profit sharing, or retirement plan.
- A partnership changes to a corporation.
- A corporation changes to a partnership.
- An individual owner of a sole proprietorship dies, and the estate takes over the business.
