Colorado Tax Tables
Colorado Tax Tables provide a complete reference of how state income tax is calculated for each supported year. These tables summarise the official rules issued by the Colorado Department of Revenue and present them in a clear structure that matches the calculations used in our Colorado Tax Calculator. They are useful for checking withholdings, estimating liability, reviewing historical tax years and understanding how state policy shapes taxable income.
Quick Access Tools
Tax Years
Select a tax year to view the official Colorado tax rates and rules used in our calculators. Each page shows the brackets or flat tax rate, deduction amounts, credit structures, withholding guidance and any year-specific updates published by the Colorado Department of Revenue. You can also access the matching Colorado Tax Calculator for precise calculations for that year.
How Colorado Calculates Income Tax
Colorado uses a progressive tax system where income is divided into brackets and each portion is taxed at its marginal rate. These rules determine how wages and other taxable income are assessed for Colorado returns, with updated tables released each year to reflect legislation and inflation changes. For a broader explanation of how tax tables work, see our Tax Tables guide.
Certain jurisdictions within Colorado also levy local or county income taxes. These appear in the annual state tax tables and may affect residents, part-year residents or nonresidents depending on local rules.
Colorado supports resident, nonresident and part-year filing rules. The tax tables help clarify which thresholds apply when income is earned both inside and outside the state.
What Is Contained in the Colorado Tax Tables?
Each tax-year page provides a structured summary of the components Colorado uses to calculate individual income tax. While details vary by year, the state tax tables generally include the following elements:
- State tax brackets and marginal rates for each filing status.
- Standard deduction amounts for each filing status.
- Itemized deductions where permitted under Colorado law.
- Dependent and family-related credits including any child-based or filer-based reductions.
- State withholding tables used by employers for payroll calculations.
Together, these elements provide a transparent breakdown of how Colorado calculates tax for each year. This structure helps taxpayers review year-to-year changes, employers validate payroll withholding and financial planners analyse how Colorado’s rules differ from federal requirements. All values shown in our Colorado Tax Tables match the official figures published by the state.
Frequently Asked Questions
Can I claim a credit for taxes paid to another state?
Residents may claim a credit for tax paid to another state on the same income.
Roth 401(k) vs pre-tax—CO impact?
Roth is after-tax (no current reduction); pre-tax lowers current CO/federal taxable income.
Can nonresidents owe CO tax on wages?
Yes—on CO-source wages (work performed in CO).
Does Colorado tax unemployment benefits?
Generally yes—unemployment is usually taxable for CO PIT (subject to any temporary exceptions).
Are stock options/RSUs treated specially for CO?
They’re wage income when taxed federally; CO follows federal income inclusion, subject to sourcing.
