Colorado Trade Name Filing Service
Operating a business in Colorado under a name other than your own legal name requires a Trade Name (Doing Business As) filing. In Colorado, these filings are handled at the county level — meaning you file with the county where you do business, not with the state. Our service handles the paperwork so you can focus on running your business.
What It Costs
Our flat service fee is $99. County filing fees are separate and vary by county — we'll confirm the exact amount for your county before you pay anything. No hidden charges, no upsells. Start your filing here →
How It Works
Fill out our short form with your name, desired business name, and county. We review your submission, confirm the county fee, and prepare the filing paperwork. Most Colorado Trade Name filings are processed within a few business days of submission to the county office.
Once the county approves your filing, you'll receive a certificate confirming your Trade Name registration. This certificate is what most banks require to open a business bank account under your business name.
Renewals vary by county. We'll let you know your renewal date and can handle that filing for you as well when the time comes.
