Federal Government – Internal Revenue Service (IRS)
Every business including Sole Proprietors must now be identified by a federal tax identification number, also known as a FEIN (Federal Employer Identification Number) or EIN (Employer Identification Number). Complete Form SS-4. Your FEIN number is the basis for all deposits and report filings.
In the past, Sole Proprietors with no employees were allowed to use a Social Security number for filing. Now, if you operate a Sole Proprietorship (with or without employees) you need to apply for a FEIN. Those forming businesses under all other structures such as General Partnerships, Limited Partnerships, Corporations, Limited Liability Company (LLC), Limited Liability Partnerships (LLP), Limited Partnership Associations (LPA), and Non-Profit Organizations will also need to use an FEIN.

The Secretary of State’s filing system is sometimes perceived to provide business name protection. However, filing with the Secretary of State does not provide name protection. Name protection exists under common law and with federal and state trademark laws.
The purpose of filing a trade name is to provide the public with a means of determining with whom they are doing business. If there is more than one record with the same trade name, the information in the Statement of Trade Name should provide adequate information to distinguish between the businesses.
