Why do you need to collect sales tax in Colorado?

If you’re selling goods and services in Colorado then sales tax might apply! To determine your obligation, you must understand “nexus,” which ties businesses to states for tax purposes.

Two types of nexus exist:

  1. Physical Nexus: Having a physical presence, like an office, warehouse, or employees in Colorado, triggers this type. If you do, you likely need to collect sales tax.
  2. Economic Nexus: This kicks in when your sales within Colorado exceed a certain economic threshold. Even without a physical presence, surpassing this threshold requires collecting sales tax.

Is what you’re selling taxable in Colorado?

Now that you’ve grasped the basics of Colorado’s sales tax and nexus thresholds, let’s delve into whether your specific products or services are taxable.

Here’s how to collect sales tax in Colorado

  1. Get a Sales Tax License: Register online or by mail with the Colorado Department of Revenue (CDOR).

Let’s say you run a clothing store in Denver, Colorado. A customer purchases a jacket for $50.00.

  • Denver has a combined sales tax rate of 8.81% (2.9% state + 5.91% local).
  • Sales tax = Item price x Sales tax rate = $50.00 x 8.81% = $4.40
  • Total item price = $50.00 (item price) + $4.40 (sales tax) = $54.40


Do you have a physical nexus in Colorado?

In Colorado, having a physical nexus determines your obligation to collect and remit sales tax on sales to Colorado residents. Here’s a quick guide to understand if you have a physical nexus in Colorado:

  • Physical Presence: Owning or leasing office space, retail space, a warehouse, or any other real property in Colorado establishes a physical nexus.
  • Inventory Storage: Storing products within Colorado, even through a fulfillment service like Amazon FBA, can create a physical nexus.
  • Employees or Representatives: Having employees or sales representatives who regularly solicit sales in Colorado (even if they don’t live there) might trigger physical nexus.
Do you have an economic nexus in Colorado?

Colorado, like many states, also has economic nexus laws. This means exceeding a certain sales threshold within the state (currently $100,000) can create nexus, even without a physical presence.

What is use tax in Colorado?

  • You buy something online or by mail from an out-of-state retailer who doesn’t collect Colorado sales tax.
  • You purchase an item in another state and bring it back to Colorado for use.
Do you need a seller/reseller permit?

In Colorado, a seller’s permit, also known as a retail sales tax license, is required for most businesses that sell taxable goods or services within the state.
