A prospective customer wants to open an account for their corporation (an Inc.) using their social security number. The customer does not believe they are required to obtain an employer identification number (EIN) since they run the business out of their home and have no employees. Can we open a business account for a corporation using an individual’s social security number instead of an EIN?

No, we do not recommend opening a business account for a corporation (which presumably will be filing an income tax return) using an individual’s social security number instead of an EIN. The IRS requires corporations to obtain an EIN and to file an income tax return — unless the corporation qualifies as a tax-exempt organization.

A corporation can obtain an EIN for free immediately after submitting an online application at IRS.gov.

A domestic corporation (including a Subchapter S corporation) must file an income tax return whether it has taxable income or not, unless it’s exempt from filing under section 501.”)
