Colorado State Tax Return

Colorado Individual Income Tax Provisions

At the state level, income tax is assessed based on three different systems, joint, combined, or a combination of the two, which accounts for how income for families is taxed. Colorado follows a joint system, meaning that both spouses' incomes are added together and taxed as a single entity. It's similar to the way the federal government applies taxes, using AGI as a base. Colorado also uses AGI as a starting point for their taxes, however there are some differences to what is taxed in comparison to the federal guidelines.

Exemptions

The following sources of income are exempt from inclusion in the tax base:

• Interest from U.S. Government Bonds
• $20,000/person ($24,000 over 65 years old) in pension or retirement income from private, public, civil service or military funds
• Recognized reservation tribal income
• Social security benefits up to $20,000/ person ($24,000 65+) in combination with pension income limitations
• Up to $100,000 of capital gains from specific state sources is exempt after being held for five continuous years

Deductions

Deductions at the state level also follow many federal guidelines, and in the state of Colorado, the standard deduction is exactly the same as the federal, as well as itemized deductions. One of the biggest differences in the state law from the federal is that state income taxes are non-deductible.

However, deductions exist for state-qualified tuition programs, wildlife mitigation costs, military family relief donations, and medical savings account contributions.
