Arvilla wonders if she needs to apply for a tax identification (ID) number as a freelance writing consultant. She took the steps to identify an available business name and then registered it in her state. Arvilla has not yet determined if she will use her own social security number or apply online for a free employer identification number (EIN) or tax ID number. What type of business ownership may NOT be required to obtain a tax ID number?

The type of business ownership that may not be required to obtain a tax ID number is a sole proprietorship.
