Colorado charges 2.9% state sales tax, plus local taxes that vary by county and city
Colorado's state sales tax rate is 2.9%, one of the lowest in the country. However, most purchases in Colorado are subject to additional local sales taxes imposed by counties, cities, and special districts. The total tax you pay depends on where you make the purchase. A $100 item might cost $105.90 in one location and $108.50 in another, depending entirely on local rates in that area.
The state rate of 2.9% applies to most tangible goods — items you can touch and take with you. It does not explore to groceries, prescription medications, or most services. Local taxes, which range from about 0.1% to over 8% depending on location, are added on top of the state rate. This means your total sales tax bill is the state rate plus whatever your local jurisdiction charges.
Colorado does not tax services the way many states do. If you hire a plumber, buy a haircut, or pay for car repair, you typically pay no sales tax on the service itself — though any parts or materials included may be taxed. This distinction matters because it keeps the tax burden lower on service-based purchases than in states with broader service taxes.
Key Takeaways
- Colorado's state sales tax is 2.9%, but your total tax rate also includes local taxes that vary by county and city, ranging from roughly 0.1% to over 8%.
- Groceries and prescription medications are exempt from Colorado sales tax, but prepared food, candy, and soft drinks are taxed.
- Most services like haircuts, repairs, and professional fees are not taxed, though materials and parts used in those services may be.
- The tax is collected by the seller at the point of sale, so you see the final amount when you check out.
What is and isn't taxed in Colorado
Colorado taxes most physical goods you purchase — clothing, electronics, furniture, and household items all carry the full state plus local tax. The key exemptions are groceries (unprepared food you cook at home) and prescription medications. These are considered necessities and are not subject to any sales tax.
The line between taxed and untaxed food can be confusing. Unprepared groceries like bread, milk, vegetables, and meat are tax-free. But prepared food — restaurant meals, deli sandwiches, bakery items, and hot food from a grocery store — is taxed. Candy and soft drinks are also taxed, even if you buy them at a grocery store, because they are not considered basic food items.
Services generally escape sales tax in Colorado. You do not pay sales tax on labor for repairs, haircuts, dental work, or consulting. However, if the service includes materials or products, those materials may be taxed. For example, a plumber's labor is not taxed, but the pipe and fittings they install are. The seller should separate these on your receipt so you can see what was taxed and what was not.
How local sales taxes work on top of the state rate
Every county in Colorado has its own local sales tax rate, and many cities and special districts add their own rates on top of that. This creates a patchwork where the total tax you pay depends on your exact location. Denver's combined rate is different from Boulder's, which is different from a small town in rural Colorado.
Local taxes fund schools, roads, public transit, and other services specific to that area. Because each jurisdiction sets its own rate, the total can vary significantly. Some areas have a combined rate around 4% (state plus local), while others exceed 10%. Online retailers and mail-order companies must collect the tax rate for the address where the item is being shipped, not where the company is located.
If you live near a border, you might notice people driving to a neighboring county or state to make large purchases. This happens because the tax difference can be substantial on expensive items. Colorado does not prevent this — you are responsible for reporting and paying use tax on items you bring into the state from out-of-state purchases, though this is rarely enforced for individual consumers.
When you pay sales tax and how it's collected
Sales tax is collected by the seller at the point of sale. When you check out at a store or online, the tax is calculated based on the address where you are buying (in-store) or where the item is being shipped (online). You see the tax amount added to your total before you pay. The seller then sends that tax money to the state and local governments on a regular schedule, usually monthly or quarterly depending on the business size.
For in-store purchases, the register calculates the tax automatically using the store's location. For online purchases, the retailer uses the shipping address to determine the correct local rate. This is why the same item might have different tax amounts depending on which state or county you order it to.
If you are buying something for resale or for a tax-exempt organization, you may be able to avoid sales tax by providing a resale certificate or tax-exempt certificate. These are issued by the Colorado Department of Revenue and must be presented to the seller before the purchase. Without the certificate, the tax is collected.
How to find your local sales tax rate
Your combined sales tax rate depends on your county, city, and any special districts in your area. The Colorado Department of Revenue maintains a database where you can search by address or ZIP code to find the exact rate that applies to you. This is useful if you are moving, opening a business, or straightforward want to understand what you are paying.
You can also ask a local retailer or your city or county tax office. Many cities post their rates on their websites. If you are buying online, the retailer should show you the tax amount before you complete the purchase, so you can see what rate is being applied to your shipping address.
Sales tax on specific items and situations
Vehicles are taxed on the purchase price, and you pay sales tax when you register the vehicle with the Colorado Department of Motor Vehicles. The tax is based on the vehicle's value and the location where you register it. Trade-ins reduce the taxable amount — you only pay tax on the difference between the new vehicle's price and what you received for the trade-in.
Clothing and footwear are fully taxable in Colorado, with no special exemption for children's clothing or back-to-school items. Some states offer tax-free periods for school supplies or clothing; Colorado does not. Prescription medications are exempt, but over-the-counter medications like pain relievers and cold medicine are taxed.
Digital goods — software, e-books, streaming subscriptions, and digital downloads — are generally taxed in Colorado. The tax is based on where the customer is located, not where the company is. This means a subscription service will charge you Colorado's combined rate if you are a Colorado resident, even if the company is based elsewhere.
Frequently Asked Questions
Do I pay sales tax on groceries in Colorado?
No, unprepared groceries like bread, milk, vegetables, and meat are not taxed. However, prepared food (restaurant meals, deli sandwiches, hot food), candy, and soft drinks are taxed. The distinction is whether you are buying something to cook at home or something ready to eat.
What's the difference between Colorado's state tax and local tax?
The state charges 2.9% on all taxable purchases statewide. Your county, city, and local districts add their own rates on top of that. Your total tax is the state rate plus all local rates combined, which is why two people in different towns pay different amounts on the same item.
Do I owe tax on items I buy online from out-of-state companies?
Yes. If the item is shipped to a Colorado address, Colorado sales tax applies based on your shipping address. Most large online retailers now collect this automatically. If they do not, you are technically responsible for reporting and paying use tax, though this is rarely enforced for individual purchases.
Is sales tax included in the price shown in stores?
No. The price on the shelf or tag does not include sales tax. The tax is added at checkout. This is why your final bill is higher than the advertised price.
Can I avoid sales tax by buying in a different county?
For in-store purchases, yes — you would pay that county's rate. For online purchases, no — the tax is based on your shipping address, not where you buy from. You cannot avoid Colorado sales tax by ordering to a Colorado address, regardless of where the retailer is located.
