How to Pay Your Taxes Online in Colorado

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.


The Traditional Way: Paying Colorado Taxes Manually

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.

1. Go to the 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.

2. Log In (or Recover Access)

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.

3. Select the Right Tax Account

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.

4. Manually Enter Payment Details

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.

5. Save Your Confirmation

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.
