Frequently Asked Questions
What is the Colorado state income tax rate for 2025?
Colorado has a flat 4.4% state income tax for the 2025 tax year — every taxpayer pays the same rate regardless of income. Colorado taxes federal taxable income directly, so your federal standard deduction flows through to the state calculation.
How is Colorado state income tax calculated?
Colorado applies its flat 4.4% rate to your federal taxable income (income after the federal standard deduction). This calculator applies the latest published Colorado figures automatically.
How much tax will I pay on a $75,000 salary in Colorado?
Roughly $2,607 in Colorado state income tax for a single filer taking the standard deduction in 2025. Add about $7,949 of federal income tax and $5,738 of FICA (7.65%), plus about $330 in CO FAMLI, for total taxes near $16,624 and take-home around $58,377. Credits and other income can change this.

About 22.2% for a single filer earning $75,000 in 2025: federal income tax (~10.6%), FICA (7.65%), and Colorado state tax (~3.5%) plus state payroll deductions. Your exact percentage depends on income, filing status, and pre-tax contributions like a 401(k).

Partially. Coloradans 65+ can subtract all federally taxable Social Security; ages 55–64 can too if AGI is at or below $75,000 single / $95,000 married filing jointly (from tax year 2025). Younger recipients follow federal treatment.
