How it works

  1. 1Choose whether you are adding tax to a price or removing it from a total you already paid.
  2. 2Enter the amount. The rate is pre-filled with Colorado’s combined average of 7.89%, which is an average of very different local rates — replace it with the rate for the exact city or county where the sale happens.
  3. 3Read the tax and total below; both update as you type, so you can compare two local rates side by side.

Frequently asked questions

What is the sales tax rate in Colorado?
Colorado charges a state sales tax of 2.9%, plus local taxes averaging 4.99%, for a combined average of 7.89%. That combined figure is above the national average of 7.53%, ranking Colorado 16 out of 51 when the states and the District of Columbia are ordered from highest to lowest. Rates are effective January 1, 2026 according to the Tax Foundation.
How is sales tax structured in Colorado?
Colorado has the most fragmented sales tax system in the United States. Home-rule cities define their own taxable base and collect their own tax, so a product exempt at state level can still be taxable inside a city, and a seller may file returns with a long list of separate jurisdictions.
Why might my receipt in Colorado show a different rate?
Because 4.99% is an average, not your rate. Local sales taxes are set by counties, cities and special districts, so two towns an hour apart can differ by a percentage point or more. Sales tax is charged based on where the sale takes place, so use the exact combined rate for that location — type it into the rate box and the calculator uses it instead.
How do I work out the pre-tax price from a total?
Switch the calculator to “Remove tax from a total”. At 7.89%, a $100.00 purchase carries $7.89 of tax for a total of $107.89. Running it backwards, a $100.00 total breaks down into $92.69 of goods and $7.31 of tax — not the $92.11 you would get by subtracting 7.89% from the total, which is the mistake this calculator exists to prevent.
How does Colorado compare with the states next door?
Colorado borders 7 states: Wyoming at 5.56%, Nebraska at 6.98%, Utah at 7.42%, New Mexico at 7.67%, Arizona at 8.52%, Kansas at 8.69%, Oklahoma at 9.06%. That spans 3.5% between Wyoming and Oklahoma, which is why border towns see the traffic they do — the gap is small on a coffee and material on a laptop. Anyone near the Wyoming line is 2.33% better off buying there, before travel costs.
Is everything taxable in Colorado?
No. The 2.9% state rate is the lowest of any state that levies one, but the local layer averages well above it — an unusual inversion that makes the statewide average almost meaningless for any specific address. More broadly, prescription drugs and medical devices are exempt in most states and services are treated differently again, so the rate is only half the question. This calculator applies whatever rate you give it and does not know what is exempt — for a specific purchase, check with the Colorado Department of Revenue.
Is this tax advice?
No. It is a calculator with published average rates pre-filled as a convenience, effective January 1, 2026. Rates change, local rates vary within a state, and exemptions are specific to what is being sold. For filing, remitting or anything with money at stake, confirm the figure with the Colorado Department of Revenue or a tax professional.

About this tool

Colorado charges a state sales tax of 2.9%, plus local taxes averaging 4.99%, for a combined average of 7.89%. Enter a price and the calculator shows the tax and the total; switch modes and it works backwards from a total to the pre-tax amount. Because the 4.99% local figure is a population-weighted average rather than a rule, the rate box is editable — put in your own city or county rate whenever the number has to be exact.

Colorado has the most fragmented sales tax system in the United States. Home-rule cities define their own taxable base and collect their own tax, so a product exempt at state level can still be taxable inside a city, and a seller may file returns with a long list of separate jurisdictions.

The 2.9% state rate is the lowest of any state that levies one, but the local layer averages well above it — an unusual inversion that makes the statewide average almost meaningless for any specific address. That matters as much as the rate: two states with identical percentages can produce very different bills depending on what sits inside the base. For context, Colorado’s combined average of 7.89% is above the national average of 7.53%, placing it 16 of 51 among the states and the District of Columbia.

Reversing sales tax is the part people get wrong. To pull tax out of a total you divide by 1 plus the rate rather than subtracting the percentage from it. At 7.89%, a $100.00 purchase carries $7.89 of tax for a total of $107.89. Running it backwards, a $100.00 total breaks down into $92.69 of goods and $7.31 of tax — not the $92.11 you would get by subtracting 7.89% from the total, which is the mistake this calculator exists to prevent.

Limitations
The 4.99% local figure is a population-weighted average across Colorado, not a rate anyone actually pays — county, city and district rates change at their own boundaries. Use the rate for the address where the sale takes place. What is taxable is a separate question from the rate, and this calculator does not model it: the 2.9% state rate is the lowest of any state that levies one, but the local layer averages well above it — an unusual inversion that makes the statewide average almost meaningless for any specific address. Confirm anything you are filing with the Colorado Department of Revenue.
Not advice
This is a calculator and a reference table, not tax advice. For anything you are filing, remitting or relying on, confirm the figure with the relevant revenue department or a qualified tax professional.
