Retirement in Colorado: Taxes and Cost of Living
Colorado taxes retirement income at a flat 4.40%, then hands most retirees a subtraction large enough to erase much of the bill. The catch is that Social Security and pension income share one cap. Here is how the math works and what the state costs.

Colorado retirement tax rules
One flat rate applies to everything: 4.40% of taxable income, with no brackets, set by Proposition 121 starting in the 2022 tax year (Colorado Department of Revenue). A TABOR surplus can temporarily lower the rate in a given year.
The pension and annuity subtraction is what makes the state workable for retirees. Taxpayers 55 to 64 may subtract up to $20,000 of qualifying pension and annuity income a year. At 65 the cap rises to $24,000 (Income Tax Topics: Social Security, Pensions and Annuities). On a joint return each spouse figures the subtraction separately.
Social Security gets its own treatment. From 65 on, you can subtract the full amount included in your federal taxable income at any income level. Between 55 and 64 the full subtraction applies only if adjusted gross income stays at or under $75,000 single or $95,000 joint. Above those thresholds the $20,000 cap returns.
Here is the part that catches people. Whatever you subtract for Social Security comes out of the same cap, so the two do not stack. A 65-year-old with $24,000 of taxable Social Security has spent the entire $24,000 and has nothing left to apply against IRA or pension withdrawals. Colorado also offers a military retirement subtraction and a property tax, rent, and heat rebate for qualifying seniors.
Cost of living in Colorado
Colorado's index sits near 105, above the national average of 100 (MERIC). Nearly all of it comes from housing along the Front Range and in the mountain towns. Second-home demand sets those prices, not local incomes.
Move away from Denver and Boulder and the picture changes quickly. Pueblo, Grand Junction, and the eastern plains price below the national average. A retiree 100 miles out gets the same outdoor appeal at a housing cost closer to Kansas than to Colorado's reputation.
Does Colorado tax retirement income?
Yes, but the subtraction covers a lot of it. Everything is taxed at 4.40% after the age-based subtraction is applied. Here is how the four most common sources are treated.
| Income type | Taxed in Colorado? | Details |
|---|---|---|
| 401(k) / IRA withdrawals | Yes, above the cap | Subtract up to $20,000 at 55-64 or $24,000 at 65+. Remainder taxed at 4.40%. |
| Pension income | Yes, above the cap | Shares the same subtraction. PERA benefits are treated the same way. |
| Social Security benefits | Generally no | Fully subtractable at 65+. At 55-64, requires AGI of $75,000 single or $95,000 joint. |
| Capital gains | Yes | Taxed at the flat 4.40% rate along with other income. |
State tax is one layer. The retirement tax calculator estimates the federal tax on the same withdrawals.
Best places to retire in Colorado
Colorado Springs
Pikes Peak scenery, more than 240 sunny days a year, and housing that prices under Denver. A large military and veteran population supports strong VA and hospital infrastructure, which is part of why the city draws retirees from across the region.
Grand Junction
On the Western Slope, Grand Junction offers mild winters by Colorado standards, red rock country, and a regional medical center. Housing costs run below the state average, and the wine country around Palisade sits 15 minutes east.
Fort Collins
Colorado State University anchors the northern end of the Front Range, giving the city a walkable Old Town, extensive trails, and hospital access through UCHealth. Prices sit above the state average and below Boulder, and the city consistently rates well on livability measures.
Pueblo
The most affordable metro in the state, roughly 45 minutes south of Colorado Springs. Housing prices well under the national average, and the Arkansas River corridor gives residents water and trail access without mountain-town pricing.
Durango
Southwest Colorado at the edge of the San Juans, with a historic downtown and outdoor access in every direction. Costs run high for a town this size and winters are real. It suits retirees who want the mountains as daily life rather than a view.
Colorado pension system
Colorado PERA covers state employees, public school teachers, judges, and many local government and university workers. It is a defined-benefit plan built on years of service and highest average salary, with a defined-contribution option available to some members. PERA benefits qualify for the same pension and annuity subtraction as other retirement income.
Most PERA members do not pay Social Security taxes on that employment, so the pension carries more of the load. The pension calculator estimates the monthly benefit from service and salary.
