What Happens If I Don’t Use My EIN Number? Understanding Employer Identification Numbers (EIN)

An employer identification number (EIN) is permanent once the IRS assigns it to a business. The IRS cannot cancel an unused EIN. A business that changes ownership or structure may need a new EIN. For example, a sole proprietorship that becomes a corporation. Unused EIN numbers can enable identity theft by not monitoring an EIN.

If income is $0, a statement could avoid paying fees on an unused EIN.
