No, the IRS requires corporations to obtain an EIN, and we are not aware of any exceptions for corporations owned by a sole employee who works from home.
We would caution against relying on any guidance found on non-government websites, such as irs-ein-tax-id.com, which is not affiliated with IRS.gov. However, irs-ein-tax-id.com, does note that “[e]ven if your company is based out of your home, you may need to obtain an EIN if you . . . [o]perate your company as a corporation.”
Although a company that operates as a sole proprietorship may not need an EIN (and can use its owner’s social security number), it would need an EIN if the sole proprietor has established a corporation.

So, as the list above details, there are clear cases when you are required to have an EIN. . . . The flip side of the equation is that, if you work for yourself and are your only employee, you are not required to get a new EIN, plain and simple. You are free to use your social security number for all of your business, banking and tax matters if you so choose.”)
