Doing business in the Colorado District

SBA’s Business Guide lists the requirements needed to start, grow, and expand your business. Since laws and taxes vary by state, here’s what you need to do before starting your business in our area.

Business name and registration

Register your business name with the county clerk where your business is located. If you are a corporation, you will also need to register with the Secretary of State.

Business licensing and zoning

Licenses are typically administered by a variety of state and local departments. It is important to consider zoning regulations when choosing a site for your business. Contact the local business license office where you plan to locate your business. You may not be permitted to conduct business out of your home or engage in industrial activity in a retail district.
