Colorado residents looking for affordable health insurance have several options through the Affordable Care Act (ACA). Whether you need marketplace coverage through Connect for Health Colorado or qualify for Health First Colorado (the state's Medicaid program), understanding the eligibility rules and income limits can save you hundreds of dollars each month. This guide covers everything you need to know about Colorado ACA eligibility for 2026, including income thresholds, available financial help, and how to sign up.
How ACA Eligibility Works in Colorado
Colorado runs its own state-based health insurance exchange called Connect for Health Colorado. Unlike states that use the federal Healthcare.gov platform, Colorado manages enrollment, plan selection, and financial assistance through its own marketplace. This gives Colorado residents access to state-specific benefits like Colorado Premium Assistance (CPA) on top of federal subsidies.
Your eligibility for ACA coverage and financial help depends on a few key factors:
- Household income relative to the Federal Poverty Level (FPL)
- Household size (everyone you claim on your taxes)
- Immigration status (must be a U.S. citizen or lawfully present)
- Whether your employer offers affordable coverage that meets minimum standards
- Your age (some programs like CHP+ cover children specifically)
Colorado expanded Medicaid in 2014, which means there is no "coverage gap" in the state. If your income is too low for marketplace subsidies, you likely qualify for Health First Colorado instead.
2026 Income Limits for Colorado ACA Coverage
The federal government updates the Federal Poverty Level each year. For 2026, these are the FPL figures used to determine eligibility for ACA subsidies and Medicaid in Colorado.
Federal Poverty Level (FPL) for 2026
| Household Size | 100% FPL | 138% FPL (Medicaid Limit) | 250% FPL | 400% FPL |
|---|---|---|---|---|
| 1 | $15,960 | $22,025 | $39,900 | $63,840 |
| 2 | $21,640 | $29,863 | $54,100 | $86,560 |
| 3 | $27,320 | $37,702 | $68,300 | $109,280 |
| 4 | $33,000 | $45,540 | $82,500 | $132,000 |
| 5 | $38,680 | $53,378 | $96,700 | $154,720 |
| 6 | $44,360 | $61,217 | $110,900 | $177,440 |
For households larger than 6, add $5,680 per additional person to the base FPL amount.
What These Numbers Mean for You
- Income below 138% FPL: You likely qualify for Health First Colorado (Medicaid). You can apply and enroll any time of year with no waiting for Open Enrollment.
- Income between 138% and 400% FPL: You qualify for premium tax credits that lower your monthly health insurance costs through Connect for Health Colorado.
- Income between 138% and 250% FPL: You may also qualify for cost-sharing reductions (CSRs) that lower your deductibles, copays, and out-of-pocket maximums when you choose a Silver plan.
- Income above 400% FPL: You may still qualify for premium tax credits depending on whether enhanced subsidy provisions are in effect. Check with Connect for Health Colorado for the most current rules.

Types of Financial Help Available in Colorado
Colorado offers three distinct forms of financial assistance for health insurance, which is more than most states provide.
1. Advanced Premium Tax Credits (APTC)
These are federal subsidies that reduce your monthly premium. The amount depends on your income, household size, and the cost of the benchmark Silver plan in your area. You can take the credit in advance to lower your monthly payments, or claim it when you file your taxes.
Key points about premium tax credits:
- Based on your estimated income for the coverage year
- Applied automatically when you enroll through Connect for Health Colorado
- Must be reconciled on your tax return at the end of the year
- If your income changes during the year, update your application to avoid owing money at tax time
2. Colorado Premium Assistance (CPA)
This is a state-funded program unique to Colorado. CPA provides additional premium reductions on top of federal tax credits. If your net premium (after the federal tax credit) is less than the available CPA amount, only enough CPA will be applied to bring your premium down to as low as $1.
For example, if you are an individual with a $45 net premium after the federal tax credit, CPA could reduce that further toward $0. If your net premium is $100, the CPA benefit (up to approximately $80 for a single-person household) would bring your payment down to roughly $20.
CPA is applied automatically when you enroll through Connect for Health Colorado. You do not need to apply separately.
3. Cost-Sharing Reductions (CSRs)
If your income falls between 138% and 250% FPL and you select a Silver plan, you automatically receive cost-sharing reductions. These lower your:
- Deductibles
- Copayments
- Coinsurance
- Out-of-pocket maximum
CSRs only apply to Silver-tier plans. If you qualify for CSRs, choosing a Silver plan is almost always the best value, even if Bronze or Gold plans look appealing at first glance.

- Health First Colorado (Medicaid)

Step 4: Compare Plans

When Can You Enroll?
Open Enrollment
The annual Open Enrollment period for 2026 coverage ran from November 1, 2025 through January 15, 2026. If you missed that window, you still have options.
Special Enrollment Periods
You can enroll outside of Open Enrollment if you experience a qualifying life event, including:
- Losing health coverage from a job, Medicaid, or other source
- Moving to a new area
- Getting married or divorced
- Having or adopting a baby
- Changes in household income
- Turning 26 and aging off a parent's plan
Qualifying events give you a 60-day window to sign up for coverage.
Tax-Time Enrollment (Colorado Only)
Colorado offers a unique program that lets you enroll in health insurance when you file your state taxes. If you check the box on your Colorado tax return by April 15, you may qualify for a Special Enrollment Period. This is a great option if you missed Open Enrollment and do not have another qualifying event.
Medicaid and CHP+ (Year-Round)
Health First Colorado (Medicaid) and Child Health Plan Plus (CHP+) accept applications year-round. There is no enrollment window. If you qualify, you can sign up any day through Colorado PEAK or by calling 1-800-221-3943.
Health First Colorado (Medicaid) vs. ACA Marketplace
Understanding the difference between these two programs is important because your income determines which one you use.
| Feature | Health First Colorado (Medicaid) | ACA Marketplace |
|---|---|---|
| Income Limit | Up to 138% FPL | 138% to 400%+ FPL |
| Monthly Premium | Usually $0 | Varies (subsidies available) |
| Enrollment Period | Year-round | Open Enrollment or Special Enrollment |
| Application | Colorado PEAK | Connect for Health Colorado |
| Cost-Sharing | Minimal or none | Deductibles, copays, coinsurance |
If you apply through Connect for Health Colorado and your income is below the Medicaid threshold, your application will be forwarded to Health First Colorado automatically. You do not need to apply to both programs separately.
Who Cannot Get ACA Coverage in Colorado
Not everyone is eligible for ACA marketplace plans. You generally cannot enroll if:
- You are currently incarcerated
- You are not lawfully present in the United States (though some exceptions exist for certain immigration categories)
- You have access to affordable employer-sponsored coverage that meets minimum value standards
- You are eligible for Medicare (you would enroll through Medicare instead)
If you are undocumented, you are not eligible for ACA marketplace coverage or Medicaid in Colorado. However, emergency Medicaid may cover emergency medical situations regardless of immigration status.
Tips to Maximize Your Savings
-
Report income accurately. Overestimating or underestimating your income can affect your subsidies. If you receive too much in tax credits, you may owe money when you file taxes.
-
Choose Silver if you qualify for CSRs. Cost-sharing reductions only apply to Silver plans. A Silver plan with CSRs often gives you Gold-level or even Platinum-level benefits at a fraction of the cost.
-
Update your application when things change. Got a raise? Lost a job? Had a baby? Report changes within 30 days to keep your coverage and subsidies accurate.
-
Compare plans every year. Plan prices, networks, and benefits change annually. Even if you are happy with your current plan, check whether a better option is available.
-
Use free enrollment help. Connect for Health Colorado offers free assistance through certified enrollment specialists. You can get in-person or virtual help at no cost by calling 855-752-6749.
