  • About This Answer

    Our income tax calculator calculates your federal, state and local taxes based on several key inputs: your household income, location, filing status and number of personal exemptions. Also, we separately calculate the federal income taxes you will owe in the 2020 - 2021 filing season based on the Trump Tax Plan.

    How Income Taxes Are Calculated

    • First, we calculate your adjusted gross income (AGI) by taking your total household income and reducing it by certain items such as contributions to your 401(k).
    • Next, from AGI we subtract exemptions and deductions (either itemized or standard) to get your taxable income. Exemptions can be claimed for each taxpayer as well as dependents such as one’s spouse or children.
    • Based on your filing status, your taxable income is then applied to the the tax brackets to calculate your federal income taxes owed for the year.
    • Your location will determine whether you owe local and / or state taxes. more

Taxes in Colorado

Colorado State Tax Quick Facts

  • Income tax: 4.50% flat rate
  • Sales tax: 2.90% - 11.20%
  • Property tax: 0.49% average effective rate
  • Gas tax: 22.0 cents per gallon of regular gasoline, 20.5 cents per gallon of diesel

The Centennial State has a flat income tax rate of 4.50%, and one of the lowest statewide sales taxes in the country, at just 2.90%. However, because of numerous additional county and city sales taxes, actual combined rates can be as high as 11.20%. When considering these local taxes, the average Colorado sales tax rate is 7.72%.

On the other hand, homeowners in Colorado get a break on real estate taxes. The state’s property tax rates are among the nation’s lowest, with an average effective rate of just 0.49%.

A financial advisor in Colorado can help you understand how taxes fit into your overall financial goals. Financial advisors can also help with investing and financial plans, including retirement, homeownership, insurance and more, to make sure you are preparing for the future.

Colorado Income Taxes

The state income tax in Colorado is assessed at a flat rate of 4.50%, which means that everyone in Colorado pays that same rate, regardless of their income level. There are eight other states with a flat income tax. Among these states, Colorado’s rate ranks in about the middle of the pack. Colorado’s income tax is also fairly average when compared to the top rate of those states with a progressive income tax.

That 4.50% applies to Colorado taxable income, which is equal to federal taxable income. This means that taxpayers who do not itemize deductions on their federal income tax return do not have the option to do so on their state return; conversely, taxpayers who do itemize deductions federally must claim the same deductions on their state return.

There are a couple of exceptions to this. One is that taxpayers who make donations to charity, but do not itemize deductions on their federal return, may be able to deduct those donations on their Colorado state income taxes. Another is the deduction for state income taxes (also known as the SALT deduction). Taxpayers who itemize deductions federally, and claim this deduction, must add it back to their Colorado taxable federal income tax return.

Colorado Tax Credits

After calculating their initial tax bill, there are some additional tax credits Coloradoans can claim. The most significant of these are the Child Care Contribution Credit (which is equal to a percentage of the similar federal credit), the Earned Income Credit (equal to 10% of the federal credit) and the Alternative Fuel Credit, which is available to taxpayers who purchase an alternative fuel vehicle such as a battery-powered electric car.

Colorado Sales Tax

The statewide sales tax in Colorado is just 2.90%, lowest among states with a sales tax. However, as anyone who has spent time in Denver, Boulder or Colorado Springs can tell you, actual sales tax rates are much higher in most cities. This is because many cities and counties have their own sales taxes in addition to the state sales tax. The table below shows sales tax rates for all counties and the largest cities in Colorado.

Colorado Property Tax

If you’re thinking about finally investing in that Rocky Mountain ski lodge, there’s some good news: Colorado has some of the lowest property taxes in the country. The state’s average effective property tax rate (property taxes paid as a percentage of home value) of 0.49% is one of the lowest in the U.S. In some areas, effective property taxes are even lower. In Gilpin County, for example, where homeowners there pay about $791 annually in property taxes, the rate is just 0.23%.

As of 2014, marijuana is both legal and taxable in Colorado. The marijuana tax rate is a combined 30%, though consumers will only pay half of this.

The 2.9% state sales tax rate only applies to medical marijuana.
