Why 2027 ACA Open Enrollment Calls for a Fresh Look at Your Plan

Open enrollment for 2027 coverage is shaping up as the most demanding one in years. Enhanced federal tax credits have expired, carriers are moving in and out of states, and the help available to shoppers is thinner. My read is that the people who come out ahead will be the ones who actually compare plans instead of letting their current coverage roll over.

The basics that still matter

Start with the fundamentals, because they haven't changed. Eligibility for premium help is still tied to the Federal Poverty Level (FPL) guidelines for 2027, and the subsidy eligibility cutoff remains 400% FPL. Your Modified Adjusted Gross Income (MAGI) determines where you land, and the advance premium tax credit (APTC) table for 2027 shows how much help a given household income can unlock. Deadlines for open enrollment vary by state, and the official marketplace is still the right place to shop and enroll.

The bigger change sits on the back end. Starting this year, there's no longer a cap on how much of your advance subsidy you might have to repay if your actual income ends up higher than you estimated. That makes income estimates a real financial decision, not a formality.

Anyone currently on an off-exchange plan should take a hard look at moving on-exchange, even if they expect to lose federal subsidies. Fifteen states offer additional financial help to eligible on-exchange enrollees to offset the loss of federal assistance, and two states were added for 2027. Those state programs only work if you're enrolled through the exchange.

Silver plans can be the better buy for lower incomes

This is the part most shoppers get wrong. If your household earns less than 200% FPL, you're likely better off in a Silver plan, and that holds in any state. The reason is Cost Sharing Reductions (CSR). Those reductions lower your deductible, copays and coinsurance substantially, and on a high-CSR Silver plan the actuarial value jumps from roughly 70% for a standard Silver to about 94% for enrollees up to 150% FPL, or 87% for those between 150% and 200% FPL. That's why people call them "Secret Platinum" plans.

The good news is that the CSR formula isn't being weakened in 2027, unlike the premium subsidy formula. So this advice holds regardless of the premium tax credit changes. There are exceptions, though. Someone under 200% FPL might do better with a very cheap Bronze or Gold plan, so the numbers still need checking. For enrollees between 200% and 250% FPL, CSR help is much weaker, around 73% actuarial value, which makes the choice between a CSR Silver and a Silver-loaded Gold plan more of a judgment call.

How Silver loading creates cheaper Gold and Bronze plans

Silver loading is the pricing practice behind a lot of the counterintuitive numbers you'll see this season. Carriers load the cost of their CSR obligation onto the gross premium of Silver plans. Bronze, Gold and Platinum plans don't carry that load to the same degree, so Silver prices can rise sharply while other metal tiers rise only modestly.

That matters because the premium tax credit is calculated from the gross price of the benchmark Silver plan. When Silver goes up, the subsidy goes up too, and eligible enrollees can use that subsidy on any metal tier. If Silver rose 30% while Bronze and Gold rose 10%, the net premium for a Bronze or Gold plan could end up noticeably lower. Silver loading is only relevant for enrollees above 200% FPL, since lower-income households should usually stay in Silver to capture the stronger CSR benefit.

Some enrollees are already seeing the results. Even before the enhanced tax credits expired, some people could get a Bronze plan for free, and some Gold plans cost the same as Silver or less. Today, there are hundreds of counties where at least one Gold plan is priced below the benchmark Silver plan even before subsidies. After subsidies, some households still qualify for a $0-premium Gold plan. The pool of people who qualify is smaller than it was, but the option hasn't disappeared.

Premium alignment and where it's showing up

Silver loading is effectively a subset of a broader pricing approach called premium alignment. Premium alignment pushes the APTC subsidy even higher, which can improve value and affordability for a large group of enrollees. States that adopt it are generally aligned more closely with the original intent of the ACA's text, and the policy has been adopted across the political spectrum. New Mexico and Maryland have it, as do Wyoming and Texas.

In 2026, three more states put robust premium alignment policies in place: Washington, Illinois and Arkansas. The Arkansas move is worth noting because it came from a more conservative state. Two of the three states are Democratic-leaning, and one is not, which tells you how broadly the approach has spread.

The practical question for you is simple: does your state use premium alignment? If so, a Gold or Bronze plan may be cheaper than you expect, even if you earn more than 200% FPL. Check the numbers on the exchange before assuming Silver is the default answer.

The individual mandate still exists in five states

The federal individual mandate penalty dropped to zero in 2019, so it no longer applies nationally. Five states still enforce their own coverage requirements, each with its own penalty:

• California: at least $950 per adult and $475 per dependent child
• District of Columbia: at least $845 per adult or $422.50 per child
• Massachusetts: $300 to $2,244 per person, depending on income
• New Jersey: at least $695 per adult or $348 per child
• Rhode Island: at least $695 per adult or $348 per child

Residents without coverage who don't qualify for an exemption will pay the penalty when they file their 2026 state taxes in spring 2027. If you live in one of these states, the penalty is a reason to look at coverage now, not after tax season.

Carriers are shifting in both directions

Every year brings churn. Some carriers enter new counties or states, some pull back, and existing insurers add or retire individual plans. For 2027, the list of new entrants includes CalOptima Health in California, Colorado Access in four of the state's nine rating areas, Antidote Health in Georgia and Texas, AmeriHealth Caritas in Indiana and Ohio, Aspirus in Minnesota, Oscar Health in South Carolina and Peak Health in West Virginia.

The exits are longer. Cigna is pulling out of Arizona nationally and leaving several other states, including Colorado, Georgia, Indiana, Illinois, Mississippi, North Carolina, Tennessee, Texas and Virginia. Molina is exiting in Florida, Illinois, Kentucky, Mississippi, Ohio, South Carolina and Utah. Celtic/Ambetter/Centene is leaving Delaware and New Hampshire, and Medica is leaving Iowa, Kansas and Oklahoma. Connecticut's ConnectiCare and Missouri's Cox Health Plans will still sell plans off-exchange. Louise Norris at healthinsurance.org has compiled a fuller list, and it's possible a few changes are missing from it.

If your carrier is leaving, your coverage doesn't simply vanish. Enrollees are usually mapped to a similar plan from a different carrier, or they have to actively pick a new one. Either way, you should check the new plan's network, deductible and formulary before the mapping takes effect.

Less help from navigators

The Kaiser Family Foundation has described a 90% cut to navigator funding, from $100 million for the current plan year down to $10 million for next year. KFF called it the biggest cut since the program began. Navigators are supposed to provide impartial information and services related to Marketplace coverage. Their work goes beyond enrollment to include public education and outreach, especially in underserved communities where income can change during the year, and they help people understand Medicaid and employer coverage too.

The cut lands unevenly. KFF noted that earlier grants had disproportionately served consumers in Republican-led states and rural areas. The partial offset is that 22 states now run their own state-based marketplaces, with their own outreach and navigation programs. Oregon recently launched its state-based exchange. Outside those states, expect less hands-on help, so plan to do more of the comparison work yourself.

Immigrant eligibility is narrowing

Starting with open enrollment on November 1, 2026, many previously eligible immigrants will lose access to ACA tax credits and cost-sharing help. Earlier in 2026, subsidies were already removed for hundreds of thousands of documented non-citizens, including DACA recipients and recent documented immigrants who don't qualify for Medicaid because they've lived in the U.S. for fewer than five years. For 2027, the list gets longer.

According to the National Immigration Law Center, the groups that remain eligible for ACA subsidies are green-card holders, certain Cuban and Haitian entrants, and citizens of the Freely Associated States of Micronesia, the Marshall Islands and Palau living in the U.S. Lawfully present immigrants outside those categories lose financial support. That includes refugees, asylum applicants and recipients, people who have applied for or received withholding of removal, and survivors of violence petitioning under the Violence Against Women Act. It also covers T and U visa holders, people paroled into the U.S. for more than a year, certain Afghan and Ukrainian parolees, green-card applicants, and people with Temporary Protected Status, Deferred Enforced Departure or deferred action (other than DACA).

These groups can still enroll, but at full price. For most, that's unaffordable, which makes the option a thin silver lining. If you work with clients or family members in these categories, the change means the cost math has shifted fundamentally.

Why auto-renewal is riskier this year

Shopping every open enrollment has always been smart, but this year it's close to essential. The expired federal tax credits, less generous APTC and maximum out-of-pocket thresholds, carrier changes, state-level supplemental help and Silver loading all add up to pricing that's hard to predict from last year's plan.

Louise Norris at healthinsurance.org lays out several specific risks. Auto-renewal happens right after December 15 for people who haven't manually renewed or chosen a plan. Most states keep open enrollment running into January, so you may have until at least January 15 to switch if the renewed plan isn't right. Subsidy amounts also change from year to year, and if your subsidy shrinks, a renewed plan could cost more. Auto-renewal can even drop your premium subsidy if you didn't give the exchange permission to access your financial information or didn't reconcile your subsidy on last year's tax return. If your plan is being discontinued, the exchange or insurer may pick a replacement for you, and that replacement may not match what you need. Networks and benefits also change, and the benchmark plan may not be the same one.

My advice is simple. Pull up your current plan, compare it with the alternatives on the exchange, check your subsidy estimate and make the decision yourself. If you keep your plan, that's a fine outcome, as long as you chose it deliberately. The one thing you want to avoid is waking up in January with a premium you never reviewed.

Open enrollment is still the window that matters, and the next few weeks will show whether your current plan is still the best value. Read the numbers before the deadline, not after.
