    When an Existing Business Needs a Tax ID Number

    IRS For those who have started a small business, there may be no immediate need for a tax ID number. In fact, many sole proprietorships operate with the owners personal social security number. This form of tax is allowable by the Internal Revenue Service unless the services that are offered by the small business include collection of sales tax, sales of firearms or alcohol or in the event that a small business owner decides to hire employees. But if you buy a business, you can get a Tax ID number for an existing business as well that is unique to your new business.

    More commonly referred to as an "EIN" (Employer Identification Number) there are various business interests that require an EIN including:

    Publicly traded companies - If a company offers stock to the public, they may be required to have an EIN

    Sole proprietorships with retirement plans - A sole proprietorship who elects to undertake a formal retirement plan such as a KEOGH or other qualified plan will be required to have an EIN;

    Partnerships - Certain partnerships may be required to have an EIN number since the company is owned by more than one person.

    Why get a tax ID number?

    In many cases, a tax ID number can help a business protect the identity of the owners. The owners of a company may prefer to not use their social security numbers for banking, credit or other business related activities. In some instances, this is a result of concerns arising out of potential identity theft. A tax ID number is also beneficial for filing taxes.
