Do you have nexus in Colorado?

The word “nexus” refers to a commercial connection in the state. Nexus determines the following questions for a state tax agency: Do you do business here, what kind, and how much? And when you do have nexus, that means you’re obligated to collect tax on your sales there.

So the first question for you to answer is whether you have nexus in Colorado.

You probably have nexus in Colorado if any of the following points describe your business:

• A physical presence in Colorado: a store, an office, a warehouse or distribution center, storage space, you, an employee, a representative, etc.

• A significant amount of sales in Colorado within twelve months. *

• This is called an economic nexus, a sales tax nexus determined by economic activity, i.e. - the amount of sales you make in a particular state. Any kind of economic activity could trigger the nexus, once your total sales reach a certain threshold amount.

The threshold in Colorado is $100,000 in annual sales. To learn more about how this works, check out the Ultimate Guide to US Economic Nexus.

Sales tax on shipping charges in Colorado

Colorado does apply sales tax to shipping costs. The rule of thumb is that if what you’re selling is subject to tax, then the shipping charges are also subject to tax. (And vice versa is true: If the item being shipped is not subject to sales tax, neither are the shipping charges.)

If you happen to be shipping products that are both taxable and nontaxable, then shipping charges for the entire shipment are subject to tax.

When to file taxes in Colorado

When you register for sales tax, Colorado will assign you a certain filing frequency. You’ll be asked to file and pay sales tax either monthly, quarterly, or annually.

Usually the frequency they choose is based on the amount of sales tax you collect from buyers in Colorado. High-revenue businesses file more frequently than lower volume businesses, for example.

Colorado sales tax returns are due on the 20th day of the month following the reporting period. If the due date falls on a weekend or holiday, then your sales tax filing is generally due the next business day.

How to file taxes in Colorado

When tax time rolls around in Colorado, whether it’s monthly or annually, you must do three things:

1. Calculate how much sales tax you owe
2. File a sales tax return
3. Make a payment

Colorado requires that any seller with a sales tax permit file a sales tax return on your due date, even if you don’t have any sales tax to report or pay. Even if you didn’t make a single sale in Colorado during the reporting period, you should must do a “zero tax filing.”
