Colorado Sales Tax Rates and What They Apply To

Colorado's statewide sales tax rate is 4.63 percent

Colorado charges a state sales tax of 4.63 percent on most retail purchases. This is the base rate that applies everywhere in the state. However, your total sales tax bill is usually higher because counties and cities add their own local taxes on top of the state rate.

When you buy something in Colorado, you pay the state 4.63 percent plus whatever your local jurisdiction charges. A purchase in Denver, for example, is taxed at a different rate than the same purchase in Boulder or Colorado Springs, because each city and county has set its own local rate. Your receipt shows the combined total, but understanding the pieces helps you know what to expect.

Key Takeaways

• Colorado's state sales tax is 4.63 percent, but your actual tax rate depends on your city and county, which add local taxes on top.
• Local sales tax rates range from about 4 percent to over 8 percent depending on where you shop, so the same item costs different amounts in different towns.
• Groceries, prescription medications, and medical equipment are exempt from Colorado sales tax, but prepared foods and over-the-counter drugs are taxed.
• Online purchases from out-of-state sellers are subject to Colorado sales tax if the seller has a physical presence in the state or meets certain sales thresholds.

How local taxes stack on top of the state rate

Every county in Colorado adds a local sales tax on top of the 4.63 percent state rate. These county rates vary widely — some are as low as 0.1 percent and others reach 3 percent or higher. Many cities then add an additional city sales tax on top of both the state and county rates.

This means your total sales tax can range from around 4.63 percent in areas with minimal local taxes to over 8 percent in cities with high local rates. Denver's combined rate, for example, is higher than a small town in a rural county. The best way to find your exact rate is to check your city or county's website or look at a recent receipt from a purchase you made locally.

What is and is not taxed in Colorado

Colorado exempts certain items from sales tax entirely. Groceries — meaning unprepared food you buy at a supermarket — are not taxed. Prescription medications filled by a pharmacist are also exempt. Medical equipment like wheelchairs, crutches, and diabetic testing supplies are generally not taxed when you have a prescription or medical documentation.

Items that are taxed include prepared foods (restaurant meals, deli items, hot foods), over-the-counter medications and vitamins, clothing, electronics, and household goods. Alcohol and tobacco are taxed at the regular sales tax rate, though tobacco also carries a separate state excise tax. If you are unsure whether a specific item is taxed, ask the cashier or check the Colorado Department of Revenue website.

Sales tax on online and out-of-state purchases

If you order something online from an out-of-state seller, Colorado sales tax applies if that seller has a physical presence in Colorado — such as a warehouse, office, or store location. Many large online retailers meet this threshold and already collect Colorado tax at checkout.

Sellers who do not have a physical presence in Colorado but meet certain sales volume thresholds are also required to collect Colorado sales tax. The threshold changes periodically, so if you are a business owner, check the Colorado Department of Revenue for current requirements. As a shopper, you will usually see tax added at checkout if it applies to your order.

Where to find your specific local rate

Your city or county assessor's office publishes the current sales tax rate for your area. You can also find this information on your city or county government website, usually under a section labeled "taxes" or "finance." Many county clerk offices have a sales tax rate lookup tool where you enter your address and see the exact combined rate.

Another quick way is to look at a receipt from any recent purchase made in your town. The receipt shows the total tax charged, and you can work backward to see what rate was applied. If you are moving to a new area in Colorado or shopping in a different town, take a moment to check the rate — it may be noticeably different from what you are used to paying.

How Colorado sales tax differs from income tax

Colorado has both a sales tax and a state income tax. These are separate charges. Sales tax is what you pay when you buy something; income tax is what comes out of your paycheck or is owed on your annual tax return. You cannot deduct sales tax from your income tax in Colorado, though you may be able to deduct it on your federal return depending on your situation.

Some states have no income tax but high sales tax, while others do the opposite. Colorado uses both, so residents pay tax at multiple points — when they earn money and when they spend it. Understanding this distinction helps you budget for the true cost of purchases and plan your annual tax obligations.
