What to do next
How it works
The calculator starts from your income after pre-tax contributions, takes federal taxable income as the base, subtracts Colorado's standard deduction and personal exemptions where they exist, and applies a flat 4.4% state income tax. Personal credits come off the tax. Colorado allows federal taxable income as the starting point.
Things to keep in mind
Some cities or counties in Colorado levy their own income or wage tax, which is not included here. Itemized deductions and state-specific credits are not applied, so filers with large deductions will owe less than shown.
Some Colorado rules, such as high-income phase-outs or special rates on certain income, are left out of this estimate. The state revenue department's own calculator or instructions have the full detail.
