Social Security Benefits
Colorado allows a subtraction for Social Security benefits.
For taxpayers age 65 and older, Social Security income is generally fully deductible from Colorado taxable income.
For younger taxpayers, limited subtractions may apply depending on age and income.
Example:
A 70-year-old receiving $30,000 in Social Security benefits may deduct that full amount from Colorado taxable income.
Pension Income in Colorado
Colorado taxes pension income, but retirees may qualify for a retirement income subtraction.
Eligible income may include:
• Private employer pensions
• Government pensions
• Federal civil service pensions
• Military retirement pay
• IRA and 401(k) distributions
The retirement income subtraction allows qualifying taxpayers to exclude up to a set maximum amount of retirement income each year.
The amount of the subtraction depends on:
• Age
• Total retirement income
IRA Withdrawals
Traditional IRA withdrawals are taxable in Colorado because they are included in federal taxable income.
However, they may qualify for the Colorado retirement income subtraction if the age requirements are met.
This includes:
• Regular withdrawals
• Required Minimum Distributions (RMDs)
• Early withdrawals
Roth IRA qualified distributions are generally not taxable because they are not included in federal taxable income.
Example:
If a 68-year-old withdraws $25,000 from a traditional IRA, up to the allowable retirement income subtraction limit may reduce Colorado taxable income.
401(k) and 403(b) Withdrawals
Distributions from 401(k) and 403(b) plans are generally taxable in Colorado if they are taxable federally.
However, these withdrawals may qualify for the retirement income subtraction, depending on age and total retirement income.
Roth 401(k) qualified distributions are generally not taxable at the state level if not taxable federally.
Age Matters
Colorado’s retirement income subtraction increases at age 65.
Taxpayers age 65 and older typically qualify for a larger retirement income subtraction than those aged 55 to 64.
The subtraction applies per taxpayer.
Military Retirement Income
Military retirement pay qualifies for the retirement income subtraction.
Colorado has also expanded deductions for military retirement income in recent years, providing additional benefits for qualifying veterans.
Veterans’ disability benefits are not taxable because they are not included in federal taxable income.
