Private service. Not a government agency.
Register Colorado is an independent, privately operated document preparation and filing assistance service. We are not affiliated with, endorsed by, or operated by the IRS, the Colorado Secretary of State, or any government agency. We do not provide legal advice, tax advice, or attorney representation.
You may file directly with government agencies. The IRS issues EINs for free; our $75 EIN charge is a private assistance fee. Our prices pay for our services, not government approval. Government fees are separate and must be confirmed before filing. Payment does not submit a government application or guarantee approval or a completion date.

For licensed professionals, Colorado also offers the professional corporation (PC). This information is general and does not replace legal or tax advice.

What is the difference between an LLC and an EIN?
An LLC is a legal entity registered with the state. An EIN is a federal tax ID number issued by the IRS. They are separate procedures and your business may need both.
How much does it cost to register my business?
EIN assistance is $75; Secretary of State registration is $150; trade name registration is $75; a periodic report is $40; and a late fee is $150 when applicable. Prices are in USD. We confirm applicable official fees and whether they are included before starting. The IRS issues EINs for free; our charge is for assistance.
What information do I need to get started?
We request contact details, business name and type, addresses and identification details. EIN requests also require an SSN in the dedicated encrypted field. Never put SSNs or ITINs in other fields or email. ID photos are uploaded privately after payment.
Are you part of the Colorado government?
No. Register Colorado is a private, independent service, not affiliated with the Colorado Secretary of State or the IRS. You can also complete these procedures directly on the official websites.
