Do you need to register in Colorado?
You generally need to register if your company is "doing business" in Colorado, for example if you:
Have an office, store or warehouse in Colorado
Employ people who live and work in Colorado
Regularly sell to, or provide services for, Colorado customers
Activities that usually don't count on their own include holding a bank account in Colorado, holding internal meetings there, and isolated one-off transactions. If you're unsure, check with your attorney or book a call with us.
Hiring a remote employee in Colorado always means opening Colorado payroll tax accounts, even when Secretary of State registration isn't required. See the payroll section below.
How to register, step by step
Choose a Colorado registered agent. See the rules below.
Check your name. If your company's name isn't available in Colorado, you'll pick an assumed name to use in the state.
File the Statement of Foreign Entity Authority online. On the Secretary of State's site, choose "File a business document," then "Foreign entity." The fee is $100.
Save your approval and Colorado ID number. You'll need them for payroll and tax registrations.
Registered agent rules in Colorado
Every business registered in Colorado must keep a registered agent with a usual place of business in the state, where legal papers can be delivered during business hours.
Using an employee as your agent is allowed, but it means legal papers go to one person's home, and they're lost if that person leaves. A commercial registered agent avoids that. Every AbstractOps plan includes registered agent service.
Periodic reports: every year
Colorado calls its annual report a periodic report. It's due every year in your periodic report month, which is based on the month you registered and is listed on your company's record. You can file up to two months early, and the fee is $25.
Filing after the due window adds a $50 late fee, and companies that don't file become delinquent and can lose their authority to do business in Colorado.
Colorado payroll accounts
If you have employees in Colorado, you'll also need:
A withholding account with the Colorado Department of Revenue.
An unemployment insurance account with the Colorado Department of Labor and Employment.
Colorado FAMLI premiums. Colorado's paid family and medical leave program applies to most employers.
Local occupational privilege taxes, where they apply. Denver, Aurora and a few other cities charge a monthly head tax on employees who work there.
