Colorado Tax Estimator

You can use the income tax estimator to the left to calculate your approximate Colorado and Federal income tax based on the most recent tax brackets.

Keep in mind that this estimator assumes all income is from wages, assumes the standard deduction, and does not account for tax credits.

Deductions

When calculating your Colorado income tax, keep in mind that the Colorado state income tax brackets are only applied to your adjusted gross income (AGI) after you have made any qualifying deductions.

Qualifying deductions might include an itemized deduction, the Colorado standard deduction, exemptions for dependants, business expenses, etc.

Remember that Colorado may have very different deduction laws from the Federal Income Tax, so you may have to write a whole new list of deductions for your Colorado income tax return.
