Does Colorado Tax IRA Distributions? Subtraction and QCDs

Yes, Colorado does tax IRA distributions, but only the portion that’s taxable on your federal return, and the rate is a flat 4.40% for the 2026 tax year. If you’re 65 or older, an age-based subtraction can shield up to $24,000 of retirement income from Colorado tax; if you’re 55 to 64, the cap is $20,000. That cap is shared with Social Security benefits, which is where the math gets interesting.¹²

How the Rate Applies to Your Withdrawal

Colorado’s income tax starts from your federal taxable income on line 15 of Form 1040, after your standard or itemized deductions.¹ The taxable portion of your IRA distribution, reported on line 4b of the 1040, is already baked into that number. Colorado then applies its flat 4.40% rate to the state figure after additions and subtractions. There are no brackets.

Before any state subtraction, a $30,000 traditional IRA withdrawal that’s fully included in federal taxable income would face $1,320 in Colorado tax.

Traditional vs. Roth

Because Colorado piggybacks on federal taxable income, the federal treatment of your withdrawal controls what the state sees.

Traditional IRA distributions from pre-tax contributions and earnings flow into federal taxable income and therefore into Colorado’s starting figure. Qualified Roth IRA distributions are tax-free federally and never appear in federal taxable income, so Colorado imposes no additional tax on them.³ A non-qualified Roth distribution is different: the earnings portion is included federally and becomes taxable in Colorado, though it may still qualify for the retirement income subtraction if you meet the age threshold.

The Retirement Income Subtraction

Colorado allows a subtraction that can meaningfully reduce, or completely eliminate, state tax on IRA distributions, pensions, annuities, and Social Security benefits. The amount depends on your age as of December 31 of the tax year.²

Age 65 or older: up to $24,000 of qualifying retirement income.
Age 55 to 64: up to $20,000.
Under age 55: no subtraction, unless you’re receiving the income as a death benefit from an inherited account.

The cap applies to the combined total of all qualifying retirement income, not to each source separately. Married couples filing jointly each claim the subtraction independently based on their own age and their own retirement income; one spouse’s IRA cannot be shifted to the other’s cap.⁴

How Social Security Eats Into the IRA Subtraction

Social Security benefits and IRA or pension income share the same cap. Every dollar you subtract for Social Security reduces what’s left for your IRA distribution.²

Starting with the 2022 tax year, taxpayers 65 and older can subtract the entire amount of Social Security benefits included in federal taxable income, even if that figure exceeds $24,000. For tax years 2025 and later, taxpayers 55 to 64 can also subtract their full Social Security benefits, but only if federal adjusted gross income doesn’t exceed $75,000 single or $95,000 joint. Above those thresholds, the 55-to-64 Social Security subtraction stays capped at $20,000.²

The practical result: a 67-year-old who subtracts $18,000 in Social Security has only $6,000 of the $24,000 cap left for IRA income. A 67-year-old whose Social Security subtraction reaches $30,000 has nothing left for IRA distributions, so every dollar withdrawn is taxed at 4.40%.

A Worked Example

You’re 66, single, with $12,000 of Social Security benefits in federal taxable income and $25,000 from a traditional IRA. Subtract the $12,000 of Social Security first. That leaves $12,000 of the $24,000 cap for the IRA. Of your $25,000 distribution, $12,000 is sheltered and $13,000 is taxable. At 4.40%, the Colorado tax on the IRA portion comes to $572.

Early Withdrawals Are Excluded

If your IRA distribution is a premature distribution for federal purposes, meaning it triggers the 10% federal early withdrawal penalty under IRC Section 72(t), it does not qualify for Colorado’s subtraction.⁵ This holds even if you’re between 55 and 59½ and would otherwise meet the age test. If a federal exception applies and the withdrawal isn’t treated as premature (disability, substantially equal periodic payments, and others listed in the instructions for IRS Form 5329), the distribution may qualify.²

Inherited IRAs

If you inherited an IRA and you’re 55 or older, your distributions qualify under the regular rules, with your own age setting your subtraction limit.²

There’s a notable exception for beneficiaries under 55. Normally no subtraction is available at that age. But if you’re receiving the IRA income as a death benefit because the original account holder died, you can subtract up to $20,000 regardless of your age.⁴ This matters for younger spouses and adult children facing mandatory distributions under the federal 10-year rule.

Qualified Charitable Distributions

A qualified charitable distribution lets you send up to $105,000 per year (for 2024, indexed going forward) directly from your IRA to a qualifying charity. A QCD is excluded from federal taxable income entirely. Because Colorado begins its calculation from that federal figure, a QCD never enters the state tax base and owes zero Colorado tax. For charitably inclined retirees who would otherwise owe state tax on an IRA withdrawal, this is one of the cleanest ways to eliminate both federal and state tax on that income.

Part-Year Residents and Nonresidents

If you moved into or out of Colorado during the year, only the IRA distributions you received while a Colorado resident are included in your Colorado income. Retirement income is not treated as Colorado-source income for nonresidents under federal law (4 U.S.C. § 114), so a distribution taken after you’ve left the state isn’t taxable here.⁶

Part-year residents allocate income on Form DR 0104PN. The retirement income subtraction still applies to the Colorado-allocated portion, subject to the same age-based limits.

Filing the Return

Finish your federal return first. The taxable amount from line 4b of your Form 1040, not the gross distribution on line 4a, is the figure that carries through to Colorado.² Federal taxable income from line 15 goes onto line 1 of Form DR 0104.⁴

Claim the subtraction on the Subtractions from Income Schedule, Form DR 0104AD. Social Security benefits go on line 3 (primary taxpayer); pension, annuity, and IRA income goes on line 4, or line 6 for a spouse on a joint return. The line 4 amount is reduced by whatever’s on line 3, so the two together cannot exceed your age-based cap. File DR 0104AD with your DR 0104 and attach copies of all 1099-R and SSA-1099 forms.⁴
