Colorado's sales tax is a tax on goods and some services that you pay at the point of sale

Colorado's statewide sales tax rate is 4.0 percent. This is the base rate that applies everywhere in the state. However, most Colorado counties and cities add their own local sales tax on top of the state rate, so your actual tax depends on where you make the purchase. A purchase in Denver will have a different total tax rate than the same purchase in Boulder or a rural county. The combined rate typically ranges from 4.0 percent to around 8.0 percent, depending on location.

Sales tax is calculated on the purchase price and added at checkout. If you buy an item for $100 in a location with a 7.0 percent combined rate, you pay $107 total. The retailer collects the tax from you and sends it to the state and local tax authorities.

  • Most tangible goods are taxable, but groceries, prescription medications, and medical equipment are exempt from sales tax.
  • Services like haircuts, repairs, and professional fees are generally not subject to sales tax in Colorado, though some specific services are taxed.

What is taxed and what is not

Most physical items you buy in Colorado are subject to sales tax. Clothing, electronics, furniture, toys, and household goods all have tax added at checkout. The same applies to prepared food, restaurant meals, and beverages.

Several categories are exempt from Colorado sales tax. Groceries—unprepared food you buy at a grocery store—are not taxed. Prescription medications and certain medical devices are exempt. Durable medical equipment like wheelchairs and oxygen equipment is also not taxed. Some items like newspapers and certain educational materials have exemptions as well.

Services are generally not taxed in Colorado. A haircut, car repair, plumbing work, or dental cleaning does not have sales tax added. However, some specific services do have tax applied, such as certain telecommunications services and specific professional services in limited circumstances. The rule is not absolute, so if you are unsure whether a particular service is taxed, ask the provider before you pay.

How local taxes change your total rate

Colorado allows counties and cities to add their own sales tax on top of the 4.0 percent state rate. Each locality sets its own rate, which is why the tax you pay varies by location. Denver has a combined rate of 7.65 percent. Boulder's combined rate is 7.6 percent. Some rural counties have rates closer to 4.0 percent or 5.0 percent.

When you make a purchase, the tax rate that applies is the rate where the sale physically takes place. If you buy something in a store in Denver, you pay Denver's rate. If you buy the same item online and it ships to a Denver address, the tax rate depends on whether the retailer has a physical presence in Colorado and how Colorado law treats that transaction. Online sales tax rules are complex and still changing, so rates can vary.

You can find your local combined rate by entering your address into Colorado's Department of Revenue sales tax lookup tool, or by asking a retailer in your area. The rate is posted at checkout or on receipts.

Who collects sales tax and where it goes

Retailers—stores, restaurants, gas stations, and online sellers—are responsible for collecting sales tax from customers. The retailer then sends the collected tax to the Colorado Department of Revenue and to the local tax authority in the jurisdiction where the sale occurred. This happens monthly or quarterly, depending on the retailer's size and the local rules.

The state portion of sales tax (4.0 percent) goes to Colorado's general fund and supports state services. The local portion goes to the county or city where the purchase was made and funds local services like schools, roads, and public safety. Some localities dedicate a portion of their sales tax to specific projects or services.

Sales tax on specific purchases

Vehicles purchased in Colorado are subject to sales tax, though the calculation can be complex if you are trading in another vehicle. The tax is typically collected at the time of registration with the Colorado Division of Motor Vehicles.

Alcohol and tobacco products are taxed at the regular sales tax rate, plus they may have additional excise taxes. Beer, wine, and spirits all have sales tax applied, and cigarettes and smokeless tobacco have both sales tax and a state excise tax.

Rental items like cars, hotel rooms, and equipment rentals are subject to sales tax. A hotel room in Colorado has sales tax added to the nightly rate. A car rental also has tax applied. These taxes are calculated and collected by the rental company at the time of the transaction.

How to understand your receipt

Your receipt shows the subtotal (the price before tax), the sales tax amount, and the total you paid. The sales tax line will show the dollar amount of tax collected. If you want to verify the rate, divide the tax amount by the subtotal and multiply by 100 to get the percentage. For example, if your subtotal is $100 and the tax is $7, you paid a 7.0 percent rate.

Receipts from different locations in Colorado will show different tax amounts for the same item because of local rate differences. This is normal and reflects the local tax rate where you made the purchase.
