Which state is easier for sellers?

For low-revenue sellers: nexus triggers first in both states because of its threshold. If you cross that first, you register there first.

On rate: Utah is friendlier for customers with a combined state + local rate of 7.42% vs 7.89%.

Neither state has a transaction-count trigger — only the dollar threshold matters.

Colorado — nexus note

Economic nexus in Colorado triggers at $100,000 in gross sales delivered into Colorado in the current or prior calendar year. No transaction count threshold.

Utah — nexus note

Utah sales tax nexus and economic nexus threshold: remote sellers must collect and pay Utah sales tax when, in the previous or current calendar year, they receive gross revenue of more than $100,000 from sales of tangible personal property, products transferred electronically, or services for storage, use, or consumption in Utah. The remote-seller requirement originally applied to sales on or after January 1, 2019; before July 1, 2025, Utah also used a 200-separate-transaction test. Marketplace sellers generally do not need a Utah sales tax license for facilitated marketplace sales unless they have Utah nexus and make sales outside a marketplace. Marketplace facilitators are treated as the seller for facilitated goods and services and are subject to Utah sales tax when they make or facilitate more than $100,000 of Utah sales in the previous or current calendar year.

Frequently asked questions

Which state has the lower sales tax nexus threshold, Colorado or Utah?
Both Colorado and Utah publish the same economic nexus dollar threshold of $100,000, so a remote seller would reach each state's published threshold at the same level of in-state sales. These are the thresholds published by each state's tax authority as of 2026-05-22; confirm against the official source before registering.
Do both Colorado and Utah have marketplace facilitator laws?
Yes. Both Colorado and Utah have marketplace facilitator laws, so marketplaces such as Amazon, Etsy, and eBay collect and remit sales tax on the sales they facilitate in both states. Direct-to-consumer sales you make outside a marketplace remain your own responsibility once you cross each state's threshold. Verified 2026-05-22.
Which has the lower sales tax rate, Colorado or Utah?
Utah has the lower combined state and local sales tax rate at 7.42%, compared with 7.89% in Colorado. These are the statewide base rate plus the average local rate; the exact rate depends on the customer's delivery address. As of 2026-05-22.
Do I need to register for sales tax in both Colorado and Utah?
It depends on where you cross each state's economic nexus threshold (or have physical presence there). Colorado's published threshold is $100,000, and Utah's is $100,000. You generally register in a state only once you cross its threshold, so you may have an obligation in one, both, or neither. Run the nexus calculator with your actual sales and confirm with each state's official source. Thresholds as of 2026-05-22.
When did economic nexus take effect in Colorado and Utah?
Colorado's economic nexus rule took effect on 2018-12-01, and Utah's took effect on 2025-07-01. Both stem from the 2018 South Dakota v. Wayfair Supreme Court decision, which let states require remote sellers to collect once an economic threshold is met.
