Colorado Tax Brackets
The state of Colorado imposes a flat tax on its taxpayer’s income. That means regardless of income level or filing status, all individuals pay the same rate. On the federal side you need to calculate your federal tax bracket based on your income. If you need help learning how tax brackets work you can read our guide on it.
|Filer Type||Tax Rate|
|Married Filing Jointly||4.63%|
|Married Filing Separately||4.63%|
|Heads of Household||4.63%|
The flat rate of 4.63 percent in Colorado has remained unchanged since 2000.
Colorado State Tax Deductions & Credits
Some tax credits are also available for Colorado citizens. For example, the Child Care Tax Credit is a popular option that allows individuals to receive a credit depending on their adjusted gross income (AGI). The credit is a percentage of the federal credit – 50 percent, 30 percent, 10 percent or zero if their AGI is over the threshold. Other significant tax credits include the Alternative Fuel Credit and the Earned Income Tax Credit (EITC).
Be sure to look at all standard & itemized deductions.
