The base sales tax rate in Colorado is 2.9%, but this does not universally apply to the whole state of Colorado, in fact, there are a variety of different sales tax rates depending on the county you are in. So, the way in which Colorado’s sales tax is calculated is the base rate of 2.9% tax throughout the whole state plus the additional percentage rate each county charges, equals the total Colorado sales tax rate you will pay or have to collect from your customers if you are a business.
Any retail, gas station/convenience store, or restaurant-related business you visit in Colorado should charge you the prevailing rate of the Colorado sales tax according to the county they are located in, and this also includes accommodations such as hotels and motels. While paying sales tax is mostly applicable to the sale of products, it may also apply to some service-related businesses such as hotels, taxi and limo services, sale of admissions, and charges for participation in games and amusement activities. If you are unsure whether your business should collect Colorado sales tax, you may want to visit the Colorado Department of Revenue (Taxation Division) website.
Paying Colorado’s sales tax as a consumer is a seamless process that you do not need to worry too much about when doing things like visiting a restaurant or retail store, booking a hotel, or taking your car in for a service. On the other hand, as a business owner or someone looking to start a business in Colorado, it is a whole different matter.
If you are responsible for collecting sales tax from your customers, you need to know exactly what your responsibilities are, and you need to follow the rules of Colorado sales tax collection, making sure you pay the State of Colorado each month for the total amount of Colorado sales tax you collect. In some instances, this may apply to online businesses, and if you participate in the Amazon FBA program, or simply have an e-commerce business selling a large volume of products to customers in Colorado, you may be subject to sales tax collection depending on where your products are warehoused and the volume of transactions each month/year.

Colorado’s sales tax is based on the base rate plus the county rate and any other special exceptions, so the rates below are indicative of the total Colorado sales tax you will pay or have to collect from your customers.
Colorado, unlike most other states, has adopted a unique way of determining its sales tax rates within the state. Most states will have a base sales tax rate, and then each county within the state will then charge additional sales tax, which added to the base state sales tax rate will equal the rate within that specific area (county or city).
However, it doesn’t work exactly like this in Colorado, the sales tax is more confusing due to Colorado sales tax being imposed at either city/county/school/transportation and SPD (special purpose district) levels. This means that the variations of Sales tax in Colorado range further than just the state sales tax and then individual county sales tax added together, there is a lot more to consider when working out what the correct sales tax is for your business within a certain area or industry within the state.
