Colorado offers online portals for handling state tax payments — but between inconsistent interfaces, complicated filing flows, and multiple account types, it’s easy to get tripped up. Whether you’re running a business in Denver, managing rentals in Boulder, or freelancing from Fort Collins, the process can quickly become time-consuming and frustrating.
Here’s what the traditional process looks like in Colorado, and how Remitian helps you skip the hassle.
Colorado business owners typically deal with several types of tax filings, including:
Sales and Use Tax
Withholding (Payroll) Tax
Corporate Income Tax
Estimated Individual Income Tax (for self-employed or sole proprietors)
Most of these are managed through the Colorado Revenue Online portal.
🔗 https://www.colorado.gov/revenueonline
This is the state’s central portal for managing business and personal taxes, including filing returns, making payments, and renewing licenses.
You’ll need to log in with a Revenue Online account. If you haven’t accessed it in a while, expect to go through password recovery or reset steps, especially if you’re managing multiple businesses or tax types.
From the dashboard, you must choose the correct account and filing period:
Sales and Use Tax
Wage Withholding
Corporate Income Tax
Individual Estimated Tax
Selecting the incorrect form or year can result in rejected filings or delayed processing.
Input all required info, including:
Colorado Account Number or FEIN/SSN
Filing frequency
Tax amount due
Payment method (bank draft, credit card, or third-party processor)
There’s little to no smart memory, so every quarter or filing period, you’re repeating the same manual steps.
The portal provides a confirmation number, but it’s up to you to save or print it. Retrieval is possible, but not always simple if you didn’t document it at the time.
Remitian replaces friction with automation. Whether you’re a creative entrepreneur, retail operator, or short-term rental host, we make Colorado tax compliance seamless.

The state gives you the tools — but Remitian gives you the experience you want.
