Colorado Paycheck Calculator
From gross salary to the number that actually hits your bank account
Colorado levies a flat state income tax of 4.4% on all taxable income for tax year 2025. Unlike progressive states where higher earners face escalating marginal rates, every Colorado taxpayer — whether earning $30,000 or $300,000 — pays the same 4.4% rate on their taxable income. This is mandated by the Colorado Constitution, which requires a single flat rate.
On top of state income tax, all Colorado workers also pay federal income tax and FICA taxes (Social Security at 6.2% and Medicare at 1.45%), just like employees everywhere else in the US. These federal deductions are the same regardless of which state you live in, so Colorado's flat 4.4% is what sets your take-home apart from states with no income tax (like Texas or Florida) or high progressive rates (like California).
Colorado also allows a standard deduction. For 2025, single filers can deduct $15,000 and married filers $30,000 before applying the 4.4% rate — so the effective rate on gross income ends up somewhat lower than 4.4%.
Worked example on a $75,000 salary (single filer): Subtract the $15,000 standard deduction → $60,000 taxable income → Colorado state tax = $2,640 (4.4% × $60,000). Add estimated federal income tax ($9,500) and FICA ($5,738), and your total annual take-home is roughly $57,100, or about $2,192 per biweekly paycheck — before any local taxes or benefit deductions.
Use this calculator to plug in your salary and the 4.4% state rate for a quick Colorado-specific estimate.
Practical example — Colorado
A single Colorado resident earning $75,000 in 2025 owes approximately $2,640 in state income tax after the $15,000 standard deduction — leaving an estimated annual take-home of around $57,100 once federal taxes and FICA are also deducted.

❓ Frequently asked questions
Does Colorado have a state income tax?
Yes. Colorado has a flat state income tax of 4.4% for tax year 2025. This rate applies to all taxable income regardless of how much you earn — there are no brackets or escalating rates.
How much is taken out of a paycheck in Colorado?
On a $75,000 annual salary, expect roughly: federal income tax ~$9,500, FICA (Social Security + Medicare) ~$5,738, and Colorado state income tax ~$2,640 after the standard deduction. That leaves an estimated take-home of about $57,100 per year for a single filer before any local taxes or pre-tax benefit deductions.
Is Colorado's income tax flat or progressive?
Colorado uses a flat tax system. Every taxpayer pays 4.4% on their taxable income in 2025. The Colorado Constitution requires a single rate for all filers, which makes the calculation straightforward compared to states with multiple brackets.
Are there any Colorado cities with a local income tax?
Colorado does not have a widespread local income tax system the way some states (like Ohio or Pennsylvania) do. However, some Colorado municipalities may have occupational privilege taxes (OPT) — for example, Denver charges a small monthly OPT on employees working in the city. Check with your employer or local jurisdiction to see if this applies to you.
How does Colorado's income tax compare to no-tax states?
Compared to states with no income tax (Texas, Florida, Nevada, etc.), Colorado's 4.4% flat rate does reduce take-home pay. On a $75,000 salary, that's roughly $2,640 more in state taxes per year vs. a zero-tax state. However, Colorado's rate is lower than many high-tax states like California (up to 13.3%) or New York (up to 10.9%).
