Colorado Income Tax Calculation For $70,000 In Wages
- Tax Year: 2023
- Filing Status: Single
- Colorado Tax Rate: 4.4%
- Federal Standard Deduction: $13,850
- Colorado Income Tax Estimate: $2,471
- Colorado Effective Tax Rate: 3.53%
To simplify and standardize the calculation across states, we assume the taxpayer has only income from Wages, salaries, tips, etc Line 1 on federal Form 1040. Colorado Form 104 begins with federal taxable income, 1040 Line 15. That means we must subtract the federal standard deduction amount of $13,850 from our 2023 wages. The result is our Colorado taxable income, which we can then multiply by the 2023 Colorado tax rate of 4.4%.
Colorado Income Tax = ( $70,000 - $13,850 ) × 4.4% = $2,471
To calculate the effective income tax rate for the state of Colorado, we simply divide the previously calculated income tax estimate by our initial $70,000 in wages.
Colorado Effective Tax Rate = $2,471 ÷ $70,000 = 3.53%
