Health Insurance Open Enrollment Guide 2026

Open enrollment is the annual window when you can sign up for or change your health insurance plan. For Affordable Care Act marketplace plans, the federal open enrollment period typically runs from November 1 through January 15 for coverage starting January 1 or February 1 depending on when you enroll. Some states with their own marketplaces (California, New York, Colorado, and others) extend deadlines through January 31. Employer-sponsored open enrollment varies by company but usually falls between October and December. Outside of open enrollment, you can only enroll or change plans if you experience a qualifying life event such as marriage, divorce, having a baby, losing other coverage, or moving to a new state. Missing the deadline means waiting until the next enrollment period unless you qualify for Medicaid or CHIP, which have year-round enrollment. Mark your calendar and start comparing plans at least 2 weeks before the deadline.

ACA marketplace plans come in four metal tiers that differ in how costs are shared between you and the insurer. Bronze plans have the lowest monthly premiums but highest out-of-pocket costs — you pay around 40 percent of healthcare costs. These work best for healthy individuals who rarely need medical care. Silver plans offer moderate premiums and cost-sharing (30 percent), and qualify for cost-sharing reductions if your income is 100 to 250 percent of the federal poverty level. Gold plans cover about 80 percent of costs with higher premiums but lower copays and deductibles — good for people with regular medical needs. Platinum plans have the highest premiums but cover roughly 90 percent of costs with minimal out-of-pocket expenses.

Premium tax credits reduce your monthly health insurance costs based on household income. You qualify if your income is between 100 and 400 percent of the federal poverty level, though enhanced subsidies now extend benefits to higher incomes as well. For a single person in 2026, this means roughly $15,000 to $60,000 in annual income. For a family of four, the range is approximately $31,000 to $124,000. The credit is calculated so that your required contribution does not exceed a percentage of your income — ranging from 0 percent for the lowest incomes to about 8.5 percent for the highest eligible incomes. You can take the credit in advance to lower monthly premiums or claim it on your tax return. Be careful with advance credits: if your income ends up higher than estimated, you may owe money back at tax time. Use our <a href='/tools/income-tax-calculator'>income tax calculator</a> to estimate your modified adjusted gross income and determine your subsidy eligibility. Cost-sharing reductions are an additional benefit available only on Silver plans for incomes below 250 percent of the poverty level.

Monthly premium is just one piece of the total cost picture. Calculate your estimated total annual cost by adding 12 months of premiums plus your expected out-of-pocket spending. Key numbers to compare include the deductible (what you pay before insurance kicks in, ranging from $0 to $9,200 for individuals), copays (fixed amounts per visit, typically $20 to $50 for primary care), coinsurance (your percentage after meeting the deductible, usually 20 to 40 percent), and the out-of-pocket maximum (the most you will pay in a year, capped at $9,200 for individuals in 2026). Check that your current doctors and preferred hospitals are in the plan's provider network — out-of-network care can cost 2 to 5 times more or may not be covered at all. Verify that your current medications are on the plan's formulary and check which tier they are on, as this affects your copay. If you take specialty drugs costing $500 or more per month, the plan's prescription coverage becomes the most important factor in your decision.

If your employer offers health insurance, compare the total cost to marketplace options before automatically enrolling. Employers typically pay 70 to 80 percent of employee premiums, making employer plans cheaper for most people. However, marketplace subsidies can sometimes beat employer plans for lower-income workers, especially for family coverage where employer contributions for dependents may be limited. Employer plans often offer additional benefits like health savings accounts (HSA) with employer contributions, wellness programs, and dental and vision bundling. If you are considering marketplace coverage, note that having access to affordable employer coverage (defined as less than 8.39 percent of household income for self-only coverage) makes you ineligible for marketplace premium subsidies. Run the numbers both ways using our <a href='/tools/budget-calculator'>budget calculator</a> to see the true monthly impact on your finances. Consider HSA-eligible high-deductible plans if you are generally healthy — the triple tax advantage of HSAs makes them powerful wealth-building tools.

If you miss open enrollment, a qualifying life event triggers a special enrollment period (SEP) lasting 60 days from the event date. Common qualifying events include losing existing health coverage, getting married or divorced, having or adopting a child, moving to a new zip code or state, turning 26 and aging off a parent's plan, and changes in household income that affect subsidy eligibility. Medicaid and CHIP enrollment is available year-round — if your income drops below your state's Medicaid threshold (138 percent of the federal poverty level in expansion states), you can apply at any time. Many people who qualify for Medicaid do not realize it. If you recently lost your job, COBRA lets you keep your employer plan for 18 months but at the full unsubsidized premium which averages $650 per month for individuals. In most cases, a marketplace plan with subsidies costs far less than COBRA coverage.
