Federal Income Tax
Federal income tax is a progressive tax withheld from your earnings based on IRS tax brackets. Your tax rate increases as your taxable income exceeds predetermined thresholds.
State Income Tax
State income tax is levied by individual state governments. Depending on the state, it can be a flat rate, a progressive scale, or zero.
Social Security
Social Security tax is a federal payroll tax under FICA that funds the retirement and disability benefits program. It is withheld at a flat 6.20% rate up to the annual limit.
Medicare
Medicare tax is withheld at a base rate of 1.45% under FICA to fund hospital insurance benefits. High earners face an additional 0.9% surtax on wages over $200k.
Pre-Tax Deductions
Pre-tax deductions (e.g. standard 401k, HSA, FSA, health premium payments) are taken from gross wages before taxes are calculated, lowering your overall tax bill.
After-Tax Deductions
After-tax deductions (e.g. Roth 401k, life insurance, union dues, charity) occur after tax withholdings are processed and do not reduce taxable wages.
Overview
Colorado uses a flat state income tax system, meaning all taxpayers pay the same tax rate regardless of their income level. While this makes calculation simpler than progressive states, you must still account for federal progressive taxes, FICA, and payroll deductions. This calculator uses the 2026 tax brackets and the Colorado flat rate of 4.40% to estimate your take-home pay.
How Taxes Work in Colorado
Colorado levies a flat state income tax of 4.40% on taxable income. Unlike progressive states, there are no progressive tax brackets to navigate. Depending on the state's rules, adjusted gross income is reduced by standard deductions or personal exemptions before applying the flat tax rate.
Federal vs State Taxes
Federal taxes are progressive and apply to your federal taxable income after subtracting the 2026 standard deduction ($16,100 for Single). State taxes are calculated separately using the Colorado flat rate of 4.40% on your state taxable income, resulting in different calculations for state vs federal taxes.
Social Security
Social Security is a federal payroll tax under FICA that funds the U.S. retirement and disability program. For 2026, both employers and employees contribute 6.20% of gross wages up to the maximum wage base limit of $176,100. Any earnings above this limit are not subject to Social Security tax.
Medicare
Medicare tax funds hospital insurance benefits. The base rate is 1.45% of all gross wages (no limit). High earners are subject to an Additional Medicare Tax of 0.90% on earnings exceeding $200,000 for Single filers, or $250,000 for Married Filing Jointly.

Common Paycheck Deductions
Common pre-tax deductions include traditional 401(k) retirement contributions, Health Savings Accounts (HSA), and health insurance premiums. These reduce both your federal and state taxable income. Post-tax deductions, such as Roth 401(k) plans or union dues, are subtracted after taxes have been computed and do not lower your taxable base.
Tips for Increasing Your Take-Home Pay
To increase your take-home pay in Colorado, consider adjusting your withholding forms (Form DR 0004 for the state, Form W-4 for federal) if you regularly receive large tax refunds. Additionally, maximizing your pre-tax retirement or health contributions lowers your taxable income, saving you money on taxes while building long-term wealth.
