As a business, do I need to collect sales tax in Colorado?
Businesses are required to collect sales tax in Colorado if they have a sales tax nexus in the state. This includes having a physical presence or reaching a specific sales level, which establishes an economic nexus. This is why understanding Colorado state sales tax obligations is crucial for compliance.
Do I have a physical nexus in Colorado?
A physical nexus in the state of Colorado is established if your business has a physical presence in the state, like an office, warehouse, or store. Even temporary physical presence, like participating in trade shows or craft fairs, can create a nexus.
In Colorado, physical nexus is typically triggered by employees or contractors engaged in customer-facing roles such as sales, marketing, or support.
How do I know if I have an economic nexus in Colorado?
An economic nexus in Colorado is determined by your sales volume. If your enterprise meets the threshold, you must register for a Colorado sales tax permit, collect tax on sales shipped to Colorado, and remit that tax to Colorado Department of Revenue.
In Colorado, economic nexus is established if your sales in the state exceed $100,000, based on Current or Previous Calendar Year.
Marketplace sales (e.g., Amazon, eBay) are excluded when calculating whether you've exceeded the Colorado economic nexus threshold.
Sales made for resale are excluded from the nexus threshold calculation for Colorado.
Non-taxable sales are included in the nexus threshold calculation for Colorado.
Once you cross the threshold, you must register by 1st day of the month after the 90-day period following the threshold being crossed.

Note: Local sales tax exemptions may differ from the state exemptions. Home rule city exemptions can vary significantly.
Is SaaS taxable in Colorado?
In Colorado, SaaS is partially taxable. The following categories are taxable:
Colorado's taxability of SaaS depends on whether the service involves a transfer of tangible personal property:
- Pre-written software (downloaded or delivered on media): taxable
- SaaS / cloud-hosted software (no software transfer, accessed remotely): generally not taxable in Colorado as no tangible property is transferred
- Custom software: generally not taxable
Colorado has been conservative in extending sales tax to pure SaaS subscriptions. However, the line between software-as-a-service and a taxable license can be unclear — verify with a tax advisor.
If you are uncertain about the taxability of your specific software product in Colorado, consult with a tax specialist.
How can a business get a sales tax permit in Colorado?
To obtain a sales tax permit in Colorado, businesses need to register with the Colorado Department of Revenue. Registration can be completed online through the Revenue Online.
You will need to provide detailed information about your business, including business type, ownership details, and the nature of your business activities.
When should a business file sales tax in Colorado?
Sales tax returns in Colorado are generally due on the 20th day of the following month for the previous period. Based on your annual tax liability, you may qualify for a less frequent filing schedule:
- Quarterly filing: Available if your annual tax liability is below $3,600 (returns due 20th day of the month following the end of the quarter)
- Annual filing: Available if your annual tax liability is below $180 (returns due January 20th of the following year)
Note: Colorado has over 70 "home rule" cities that administer their own local sales tax separately from the state. Businesses may need to register and file separately with these municipalities in addition to the state return.

- Failure to file: 10% of the tax due

Is shipping taxable in Colorado?
In Colorado, delivery and freight charges are generally taxable when they are included in the total selling price of a taxable item. However, separately stated delivery charges made by a common carrier may be exempt if the customer has the option to pick up the goods.
