Picture this: you’re running an online store and selling into the vibrant state of Colorado. You’ve got a lot on your plate and you’re juggling multiple roles, from managing day-to-day operations to coming up with clever marketing strategies.

At the back of your mind, though, there’s always one nagging worry – dealing with Colorado’s ridiculously complicated sales and use tax system regulations.

Now, we know that dealing with the tax rates across all the jurisdictions in Colorado is frustrating and annoying, but it is also essential. So, what if we told you there’s a solution to make it easier?

Enter Colorado SUTS, a platform designed to take some of the hassle out of handling the Colorado taxes for your business.

In this article, you’ll learn:

Overview of Colorado’s Sales Tax System

Colorado’s sales tax system is a mess.

To give you an overview of all the complexity involved, some of the special issues you need to know about are:

  • State-collected jurisdictions
  • Self-collected (home rule) jurisdictions
  • Combined sales tax rates
  • Special district taxes
  • And some tax exemptions and variations, just to make things a bit spicy!

Below are some details on the first two: state-collected and self-collected jurisdictions.

State-Collected Jurisdictions

Colorado imposes a base sales tax rate, which is collected on most retail sales made within the state.

In state-controlled jurisdictions, the Colorado Department of Revenue collects that sales tax, along with any additional local taxes required by counties, cities, or special districts within those areas. It then distributes the local portion back to the respective local governments.

Self-Collected (Home Rule) Jurisdictions

Home ruled cities and towns have charters that give them the autonomy to make their own decisions about areas of local concern. Because each home rule jurisdiction can draft its own charter, there is a lot of variability in laws, policies, and structures from one municipality to another.

In the case of sales tax , these cities and towns have chosen to collect their own local sales tax, independently of the state.

This means that each self-collected jurisdiction can set its own sales tax rate and has its own tax laws and regulations, complicating things for online sellers.

Important Features of the Colorado SUTS

Because sales tax is such a convoluted mess, the Colorado Department of Revenue created the SUTS system as a single point of remittance to participating home rule jurisdictions for online sellers.

Think of it as your Swiss Army knife for sales and use tax. It has some key features that will make dealing with taxes in Colorado a lot easier than having to deal with each jurisdiction individually.

GIS Tax Rate Lookup Tool

The Geographic Information System (GIS) Tax Rate Lookup Tool helps you figure out the exact tax rate you should charge based on where your customers live. It provides details about counties, special taxation districts and local governments that require sales tax remittance.

No more head-scratching over which tax rate to use!

Taxability and Exemption Matrices

Colorado SUTS also gives you a cheat sheet (we mean, “taxability and exemption matrices”) to help you know what are taxable goods or services and what are not. It’s like have a sales tax guru in your corner.

The system’s matrices provides an all-encompassing list so you can efficiently calculate the applicable rates when needed.

In short, they help clarify not only each item’s taxable status, but compute accurate individual rates, too!

Tax Compliance Support into Home Rule Cities

Colorado sales tax becomes an especially big burden for online businesses operating into home rule jurisdictions. These places have their own rules, and can become quite a tax maze.

But thanks to Colorado SUTS, there is now one place to deal with all of that. As of late 2023, 66 “Home Rule” cities have agreed to be a part of this program, including big ones like Colorado Springs and Boulder.

SUTS streamlines the tax remittance process by providing:

  • Accurate address-based tax rate calculations (like mentioned before)
  • A uniform filing form for those 66 cities
  • An automated remittance portal, while the Colorado Department of Revenue offers support and resources for businesses using the system.

This solution has helped address the complex problems caused by all the varying rates in the state.

With its user base rapidly expanding thanks to these benefits, this one-stop portal looks set to stick around into the future with everyone benefiting from its simplified approach to collecting taxes without complication or confusion.

Participating Jurisdictions

The Home Rule cities of Colorado have been granted autonomy to form and implement their own laws.

Online sellers that sell into most of these cities can utilize the SUTS system to help them determine the correct taxing jurisdictions, as well as collect tax at accurate rates specified by those particular areas.

Note: As of late 2023, 6 “home rule” cities have still not elected to participate in SUTS. That means that you’ll have to remit sales tax to them directly. For an example of what this could look like for a business, watch this video: Colorado SUTS Explained for Online Sellers.

Accurate Address-Based Calculations

Colorado SUTS uses something called “destination sourcing”, which uses the customer’s exact shipping address or delivery location to calculate tax rates appropriately.

So, if you’re selling to folks in different cities with different tax rates, no worries – SUTS has your back.

Handling Differing Tax Rates

The SUTS system doesn’t stop at calculating taxes. It can even handle items with different tax rates in the same city.

Imagine you’re selling both widgets and gadgets in Wheat Ridge. Colorado SUTS can help you sort out the correct tax rate for each item. Pretty handy, right?

How to Get Help with ALL Your Sales Tax Needs

Understanding how SUTS can help you is one thing, but if you’re an ecommerce business owner juggling multiple roles, there’s a solid chance that you are sick of dealing with sales tax in general.

Especially if you’re selling into any of the home rule cities that have not chosen to participate in SUTS. You’ll still have to remit to each of them individually, on top of your Colorado state sales tax return and the SUTS returns.

And Colorado isn’t the only highly complicated state for sales tax remittance.
