Colorado is a tax friendly state for retirees on most measures that matter: a flat 4.4% income tax paired with generous subtractions for Social Security, pensions, and annuities; property taxes among the lowest in the country plus a senior homestead exemption; no state estate or inheritance tax; and sales tax exemptions on groceries and prescription drugs. The caveat is on the spending side, where housing, homeowners insurance, and long-term care costs run above national norms and can quietly offset the tax savings.
How Colorado Taxes Retirement Income
Colorado applies a single flat rate of 4.4% to all taxable income for tax year 2026.1Department of Revenue – Taxation. Individual Income Tax Guide The rate briefly dropped to 4.25% for 2024 under the Taxpayer Bill of Rights surplus mechanism, then reverted to 4.4% starting in January 2025. A flat rate makes planning simpler on a fixed income because larger withdrawals don’t push you into a higher bracket.
Pension and Annuity Subtraction
Before you calculate your Colorado tax, you can subtract a portion of pension, annuity, and other qualified retirement income already included in your federal adjusted gross income. Retirees aged 55 through 64 can exclude up to $20,000. At 65, the cap rises to $24,000.2Department of Revenue – Taxation. Income Tax Topics: Social Security, Pensions and Annuities Beneficiaries of any age receiving a pension because of a deceased family member can claim the subtraction up to $20,000.3Department of Revenue – Taxation.

Social Security Benefits
If you’re 65 or older, Colorado lets you subtract the full amount of Social Security benefits included in your federal taxable income, with no dollar cap.2Department of Revenue – Taxation. Income Tax Topics: Social Security, Pensions and Annuities That rule has applied since 2022 and effectively wipes out state tax on Social Security for most older retirees.
For ages 55 through 64, the rules shifted starting with the 2025 tax year. You can subtract all federally taxed Social Security income if your adjusted gross income stays below $75,000 filing single or $95,000 filing jointly. Above those thresholds, the Social Security subtraction gets folded into the $20,000 pension and annuity cap.2Department of Revenue – Taxation. Income Tax Topics: Social Security, Pensions and Annuities A retiree just over the AGI threshold can owe state tax on benefits that someone slightly below would keep entirely.
Dividends, Capital Gains, and Interest
Investment income is taxed at the same flat 4.4% with no special exclusion. One useful exception: interest on U.S. government obligations, such as Treasury bonds and savings bonds, can be subtracted from your Colorado taxable income.1Department of Revenue – Taxation. Individual Income Tax Guide Interest from other states’ bonds, though exempt federally, has to be added back on your Colorado return. Interest from Colorado state and local bonds stays exempt at both levels.
Property Taxes and Senior Programs
Colorado’s effective property tax rate was 0.50% as of 2023, the 41st lowest among the 50 states. Rates are set at the county level through local mill levies, so the bill depends on where you live, but the statewide picture is consistently cheaper than most of the country.
Senior Homestead Exemption
The senior property tax exemption shields 50% of the first $200,000 of a qualifying home’s actual value, removing up to $100,000 of value from the local tax levy.4Colorado Department of Local Affairs Division of Property Taxation. Property Tax Exemption for Senior Citizens in Colorado To qualify for tax year 2026, you must have been born on or before January 1, 1961, and have owned and occupied the home as your primary residence continuously since January 1, 2016.5Colorado Department of Local Affairs Division of Property Taxation. Senior Citizen and Veterans with a Disability Property Tax Exemption and Senior Primary Residence Classification That ten-year residency rule is the hurdle most newcomers won’t clear right away.
Applications go to your county assessor by July 15 of the tax year. Once approved, the exemption stays in place unless ownership or occupancy changes, which you must report within 60 days.4Colorado Department of Local Affairs Division of Property Taxation. Property Tax Exemption for Senior Citizens in Colorado Funding depends on the state legislature and has been suspended during past budget shortfalls. Lawmakers reinstated funding for 2025 and 2026, so the exemption is currently active.
Property Tax Deferral
If you don’t qualify for the exemption, Colorado’s deferral program lets seniors postpone property tax payments until the home is sold or transferred. You must be at least 65 by the end of the prior calendar year, own and live in the property, carry no reverse mortgage, and hold at least 25% equity, with all prior taxes paid in full.6Treasury. Property Tax Deferral Program FAQ
The deferred balance accrues interest. For May 2026 through April 2027, the rate is 4.238%, resetting annually with 10-year Treasury rates. Applications go to the county treasurer between January 1 and April 1.6Treasury. Property Tax Deferral Program FAQ The deferral doesn’t erase the bill, but it can help house-rich, cash-poor retirees.
Sales Tax
The state sales tax rate is 2.9%, one of the lowest base rates in the country.7Department of Revenue – Taxation. Sales Tax Rate Changes Cities, counties, and special districts stack their own levies on top, so combined rates in developed areas commonly land between 7% and 9.25%. Commerce City in Adams County reaches 9.25% once city, county, regional transit, and cultural facility taxes are added.
Two exemptions matter most for retirees. Groceries for home consumption are exempt from the 2.9% state tax, though some local jurisdictions still tax them.7Department of Revenue – Taxation. Sales Tax Rate Changes Prescription drugs are fully exempt from state sales tax.8Justia. Colorado Revised Statutes Title 39 – Section 39-26-717 If medications or grocery bills dominate your monthly spending, those exemptions add up at checkout.
No Estate or Inheritance Tax
Colorado imposes no state estate tax and no inheritance tax. The state once collected a pick-up estate tax tied to the federal credit for state death taxes, but Congress phased that credit out in 2001 and Colorado never replaced it. Your estate can still owe federal estate tax above the federal exemption, which is set to drop significantly in 2026 as provisions of the Tax Cuts and Jobs Act expire, but Colorado adds no further layer.
TABOR Refunds
The Taxpayer Bill of Rights caps how much revenue the state can collect, and surplus revenue is returned to taxpayers. Colorado residents received substantial TABOR refunds in recent years, and refunds are expected for 2026, though smaller than the unusually large checks in prior cycles. Refunds appear as credits on your state income tax return, which means you have to file a Colorado return even if your taxable income is otherwise zero. Retirees with modest income sometimes skip filing and leave the refund on the table.
Where the Tax Savings Get Eaten
A tax verdict alone can mislead if you don’t factor in the cost side. Colorado’s overall cost of living exceeds the national average, driven mostly by housing along the Front Range. Median home prices statewide have hovered around $550,000 in recent years, with Denver, Boulder, and Colorado Springs often well above. Two-bedroom rents typically run between $1,800 and $2,500 depending on location.
Homeowners insurance is the surprise line item. Colorado has posted some of the steepest premium increases in the nation over the past decade. The largest driver isn’t wildfire but hail, which accounts for roughly 50% of premium costs along the Front Range and eastern plains. Wildfire adds anywhere from about 1% in Denver to nearly 25% in mountain communities.9Colorado Governor Jared Polis. Governor Polis and Division of Insurance: We Must Find Innovative Solutions to Save Colorado Homeowners Money on Insurance Costs Annual premiums above $4,000 are now common in hail-prone areas.
Long-term care is the other financial risk that dwarfs the tax picture. Assisted living averages roughly $5,000 to $5,100 per month statewide, higher in Denver and mountain resort towns. In-home care through an agency runs $25 to $35 per hour, putting full-time coverage well above $5,000 a month. Medicaid can cover nursing home and home and community-based services, but eligibility is tight. For 2026, the income limit for those programs is $2,982 per month for a single applicant, and Colorado applies the standard 60-month look-back on asset transfers. Gifts or below-market transfers within five years of application can trigger a penalty period, so planning usually needs to begin several years before care is needed.
Put together, the tax rules favor retirees who bring pension, Social Security, and modest investment income into Colorado; the cost structure works against those buying into an expensive housing market or facing years of paid care. The state is genuinely tax friendly. Whether it’s affordable friendly depends on what you’ll spend once you arrive.
