ACA Marketplace Plans: A 2026 Guide to Coverage in the Southeast
ACA marketplace plans are health insurance plans sold on HealthCare.gov under the rules of the Affordable Care Act. They’re often called “Obamacare plans,” “exchange plans,” or simply “marketplace plans.” For most working-age adults in the Southeast who don’t have employer coverage, they’re the most affordable way to get comprehensive health insurance.
What sets marketplace plans apart from private off-marketplace coverage is two things: premium subsidies and standardized consumer protections. About four out of five marketplace shoppers qualify for a premium tax credit that lowers their monthly cost — sometimes to zero. Every plan covers pre-existing conditions, the ten essential health benefits required by the ACA, and free preventive care. This guide walks through how marketplace plans are structured, what they cost in 2026, who they’re best for, and how to choose the right one.
ACA Marketplace vs. Private Health Insurance — What's the Difference?
Both marketplace plans and private (off-marketplace) plans are sold by private insurance companies. The key differences come down to where you buy them, whether you can get a subsidy, and which protections apply.
| ACA Marketplace | Private (Off-Marketplace) | |
|---|---|---|
| Where you buy | ACA Agent to guide you through HealthCare.gov | Directly from carrier or agent |
| Premium subsidies | Available (most enrollees qualify) | Not available |
| Pre-existing conditions | Always covered | Covered on ACA-compliant plans only |
| Plan structure | Standardized metal tiers (Bronze/Silver/Gold/Platinum) | Wider variety, including non-ACA alternatives |
| Networks | Often narrower | Often broader |
| Best for | Subsidy-eligible households | Higher earners, gap coverage, flexibility seekers |

The Metal Tiers — Types of ACA Marketplace Plans
Marketplace plans are organized into four main “metal tiers” plus a separate Catastrophic category. The tier names describe how costs are split between you and the insurance company — not the quality of the medical care.
1. Bronze Plans
Bronze plans have the lowest monthly premiums and the highest deductibles. The insurance company pays about 60% of covered medical costs on average; you pay about 40%.
What this means in practice: You’ll pay less every month, but if you actually need medical care you’ll pay a lot before insurance kicks in. Deductibles on Bronze plans are typically $7,000 to $9,000.
Best for: Healthy adults who rarely use medical care and want catastrophic protection at the lowest possible monthly cost. Also a common choice for younger self-employed workers and freelancers.
2. Silver Plans
Silver plans are the most popular tier in the marketplace, and there’s a specific reason: cost-sharing reductions (CSRs). Households earning under 250% of the federal poverty level can only get extra help with deductibles, copays, and out-of-pocket maximums on a Silver plan — not on Bronze, Gold, or Platinum.
The insurance company pays about 70% of covered medical costs on average; you pay about 30%. With a CSR-enhanced Silver plan, that effective coverage can rise to 87% or even 94%, making Silver plans behave like Gold or Platinum at a Silver price.
Best for: Subsidy-eligible households, especially those under 250% of the federal poverty level. For many southeastern shoppers, Silver is the right answer by default.
3. Gold Plans
Gold plans have higher monthly premiums and lower deductibles. The insurance company pays about 80% of covered medical costs on average; you pay about 20%.
Best for: People with regular medical needs — ongoing prescriptions, frequent specialist visits, or known upcoming procedures. Also a strong choice for older adults who anticipate using more care.
4. Platinum Plans
Platinum plans have the highest premiums and the lowest out-of-pocket costs. The insurance company pays about 90% of covered medical costs on average; you pay about 10%. Deductibles are often a few hundred dollars or zero. These plans are not available in all states.
Best for: People with chronic conditions, expensive prescriptions, expected major procedures, or anyone who would rather pay more each month for predictable, low costs at the doctor.
Platinum plans are not available in every state or county — check your area before counting on this option.
5. Catastrophic Plans
Catastrophic plans have very low monthly premiums and very high deductibles (around $9,450 in 2025). They’re meant for worst-case scenarios — a serious accident or major illness — not routine care.
To qualify, you must be under 30 OR have a hardship or affordability exemption.
Best for: Healthy young adults under 30 who want emergency-only coverage at the lowest possible monthly cost.
How Premium Subsidies Work
Premium tax credits — what most people just call “subsidies” — are the main reason ACA marketplace plans are so much more affordable than off-marketplace alternatives. Here’s how they work.
The basics:
- Subsidies are based on your household income and family size
- They lower your monthly premium directly — you don’t have to wait until tax time to claim the savings
- You can apply them to any metal tier (Bronze, Silver, Gold, or Platinum)
Who qualifies:
The general rule is that subsidies are available to households earning between roughly 100% and 400% of the federal poverty level. Under current rules, many higher earners can also qualify if the benchmark Silver plan in their area would otherwise cost more than 8.5% of their household income.
Rough income ranges where most southeastern households see meaningful subsidies in 2026:
- Single person: $15,000 – $60,000/year
- Couple: $20,000 – $80,000/year
- Family of 4: $30,000 – $120,000/year
These are estimates. Subsidy eligibility and amounts depend on your specific income, family size, ZIP code, and the cost of plans in your area. The only way to know what you qualify for is to enter your actual numbers — a licensed agent can run this for you at no cost.
Cost-sharing reductions (Silver-only):
On top of the premium tax credit, households earning under 250% of the federal poverty level qualify for cost-sharing reductions on Silver plans. These reductions lower deductibles, copays, and out-of-pocket maximums — sometimes dramatically.
If you qualify for CSRs, a Silver plan is almost always the smart choice. A CSR-enhanced Silver plan can have lower out-of-pocket costs than a Gold plan at a fraction of the premium.
How Much Do ACA Plans Cost in the Southeast in 2026?
Marketplace premiums vary by state, age, tobacco use, and metal tier. Here are realistic 2026 monthly premium ranges for a 40-year-old non-smoker buying a benchmark Silver plan before subsidies in your state:
| State | Typical Silver Plan (Pre-Subsidy) |
|---|---|
| Texas | $450 – $550 |
| Florida | $500 – $600 |
| Georgia | $475 – $575 |
| North Carolina | $525 – $650 |
| South Carolina | $500 – $600 |
| Tennessee | $475 – $575 |
| Alabama | $575 – $700 |
| Mississippi | $575 – $700 |
| Louisiana | $525 – $650 |
| Kentucky | $425 – $525 |
The number that actually matters: what you pay after subsidies. Most marketplace shoppers in the Southeast end up paying somewhere between $0 and $250 per month after premium tax credits are applied. About 4 in 5 enrollees qualify for a subsidy of some kind, and many lower-income enrollees pay nothing at all.
Who Should Choose an ACA Marketplace Plan?
Marketplace plans make the most sense in these situations:
- You qualify for a premium subsidy. This is the single biggest factor. If your household income falls within subsidy range, marketplace coverage is almost always cheaper than equivalent off-marketplace coverage.
- You’re self-employed, freelance, or a 1099 contractor. Most southeastern self-employed workers qualify for meaningful subsidies, and ACA plans are designed for variable-income households.
- You’re between jobs. A marketplace plan with a subsidy is often cheaper than COBRA from your old employer.
- You’re an early retiree. Adults aged 55–64 who aren’t yet on Medicare frequently qualify for substantial subsidies on marketplace plans.
- You have a pre-existing condition. Every marketplace plan must cover pre-existing conditions without higher premiums. This is a critical protection that short-term and indemnity plans don’t offer.
- You want guaranteed coverage of essential health benefits. All marketplace plans cover preventive care, prescriptions, mental health, maternity, and the other ACA essentials.
If any of these apply to you, the marketplace is almost always the right starting point.

How to Choose the Right ACA Marketplace Plan
Use this checklist when comparing marketplace plans:
- Estimate your household income for the year. Be as accurate as you can. Underestimating means a smaller subsidy now and a possible refund at tax time. Overestimating means a bigger subsidy now and a possible repayment.
- Check your CSR eligibility. If your income is under 250% of the federal poverty level, focus on Silver plans to capture the cost-sharing reductions.
- Add up your typical year of healthcare. Doctor visits, prescriptions, ongoing conditions. If you barely use the system, Bronze may save money. If you have regular needs, Gold or Platinum often pays off.
- Verify the network. Make sure your doctors and your preferred hospital are in-network. Marketplace networks are sometimes narrower than off-marketplace, so check carefully.
- Look at the deductible AND the out-of-pocket maximum. The deductible is what you pay before insurance kicks in. The out-of-pocket max is the most you’d pay in a worst-case year.
- Check the prescription formulary. Confirm your medications are covered and what tier they’re on.
- Compare at least three plans in your tier of choice. Pricing and networks vary significantly between carriers in the same county.
When Can You Enroll?
Open Enrollment (2026 plan year): November 1, 2025 – January 15, 2026 in most southeastern states. To have coverage effective January 1, you typically need to enroll by December 15.
Special Enrollment Period (year-round): If you’ve had a qualifying life event in the last 60 days, you can enroll outside of Open Enrollment. Qualifying events include:
- Losing job-based coverage
- Getting married or divorced
- Having a baby or adopting
- Moving to a new ZIP code or state
- Aging off a parent’s plan at 26
- A change in income that affects subsidy eligibility
- Becoming a U.S. citizen
- Release from incarceration
If you miss Open Enrollment and don’t qualify for a Special Enrollment Period, your options narrow to short-term medical or other off-marketplace alternatives — see our private health insurance guide for those options.
Frequently Asked Questions
Are ACA plans the same as Obamacare?
Yes — “Obamacare” is the informal name for the Affordable Care Act, the 2010 law that created the marketplace and these plan rules. ACA plans, marketplace plans, exchange plans, and Obamacare plans all refer to the same thing.
Do I have to use HealthCare.gov to buy an ACA plan?
You can apply through HealthCare.gov directly, work with a licensed agent (free to you — agents are paid by carriers), or use a comparison platform. The plan and subsidy are the same regardless of how you enroll. Many people prefer working with an agent because comparing dozens of plans on your own is time-consuming.
Will I lose my doctor if I switch to a marketplace plan?
Maybe. Marketplace plan networks are sometimes narrower than off-marketplace plans. Always confirm your doctors and hospital are in-network before enrolling.
What happens if I don’t have health insurance?
The federal individual mandate penalty was eliminated in 2019, so there is no federal tax penalty for being uninsured. However, going without coverage means you’re exposed to the full cost of any medical care you need — a single hospital stay can run tens of thousands of dollars.
What if my income changes during the year?
Report income changes to the marketplace as soon as possible. If your income goes up, your subsidy may decrease. If your income goes down, your subsidy may increase. Keeping the marketplace updated avoids surprises at tax time.
