The S or C corporation status is determined when filing with the Internal Revenue Service (IRS), only. Questions should be addressed to the IRS or your legal, business, or tax advisor(s).

Once you have filed your business with the Secretary of State’s office, you may need to research federal, state, county, and local government licensing requirements. Some licenses are issued at the Colorado Department of Regulatory Agencies (DORA) depending on the type of business you are conducting. Other licenses are issued through local city or county offices.
