You renew your health insurance plan every fall without much thought. This year’s bill makes you do a double take. The 2027 ACA open enrollment period opens November 1, 2026. It follows a year when average marketplace premium payments jumped 58 percent. Congress let enhanced subsidies expire, and millions of buyers, especially people under 35, felt the hike immediately. Here’s what changed, what’s coming next month, and how to keep next year’s bill from blindsiding you too.
Why This Hits Young Adults and the Self-Employed Hardest
Young adults absorbed the sharpest hit from this shift. People ages 18 to 34 accounted for 46 percent of the Marketplace’s enrollment losses in 2026. That’s a big share, since young adults make up a smaller slice of total enrollees. That group’s enrollment dropped 8 percent, the steepest decline of any age bracket.
Many of them buy coverage on their own because no employer plan exists yet. That group includes freelancers, part-time workers, and anyone building income through a side hustle. If your income varies month to month, that unpredictability now extends to your health coverage too. Browsing Money Under 30’s side hustle ideas can help you build a steadier income to plan around.
Self-employed workers face a second wrinkle on top of the higher sticker price. Marketplace subsidies phase out as income rises. For someone whose income swings with gig work or freelance contracts, a wrong estimate now costs more.
What Actually Happened to Premiums This Year
Enhanced premium tax credits expanded ACA subsidies starting in 2021. Congress let them lapse at the end of 2025, and the lapse hit paychecks fast. Average monthly premium payments rose from $113 to $178, a 58 percent jump.
That’s according to the Kaiser Family Foundation’s analysis of 2026 Marketplace premiums and deductibles. Deductibles also climbed 37 percent to an average of $3,786 per person. The Marketplace lost 4.8 million enrollees in 2026 as a result, dropping from 22.3 million people to roughly 17.5 million. That’s the biggest single-year drop since the Marketplace opened.
What the 2027 ACA Open Enrollment Period Changes
Open enrollment for 2027 coverage starts November 1, 2026, and runs into mid-January in most states. Premiums will rise again. Insurers filed a median proposed rate increase of about 15 percent for 2027, though the range varies widely by state. Vermont, Iowa, and Utah filed increases under 7 percent, while Arizona filed near 29 percent. Subsidy amounts track the benchmark Silver plan’s cost, so they’ll rise too. That still leaves most buyers with a smaller tax credit and a higher bill. The out-of-pocket maximum is also climbing, from $10,600 this year to $12,000 for 2027. That raises the ceiling on what one bad health year can cost, even with insurance.
Watch for the Subsidy Cliff This Year
A subsidy cliff happens when your income crosses a threshold and your tax credit drops fast, sometimes to zero. Before 2021, that cliff sat at 400 percent of the federal poverty level. The enhanced credits have smoothed that cliff out since then. With the enhanced credits gone, part of that old cliff effect is back for some income ranges. That depends on your state and which plan you choose.
A single mistake on your income estimate can mean repaying hundreds of dollars in subsidies at tax time. Pad your estimate to lower that risk. Building an emergency fund also gives you a cushion if your income comes in higher than planned. Check your estimate again partway through the year. A raise, a new client, or a strong side hustle month can change what you’ll actually earn.
What to Actually Do Before November 1
Start by pulling up last year’s plan and this year’s renewal notice side by side. Compare the premium, deductible, and out-of-pocket maximum line by line, instead of assuming the price stays close to last year’s. Then shop the full Marketplace instead of auto-renewing. Plan options and subsidy amounts both shift year to year. Last year’s cheapest Bronze plan might not be the cheapest one for 2027. Finally, estimate your 2027 income using your most recent pay stubs or invoices before you enroll. A careful estimate now protects you from an unpleasant subsidy repayment next spring.
Frequently Asked Questions About 2027 ACA Open Enrollment
When Does 2027 Open Enrollment Start?
Open enrollment for 2027 ACA coverage starts November 1, 2026. Most states keep it open into mid-January, though a few states set their own deadlines.
Why Did My Premium Go Up So Much This Year?
Congress let enhanced premium tax credits expire at the end of 2025. That change raised the average Marketplace premium payment by 58 percent for 2026.
Will My Subsidy Disappear Completely?
It depends on your income and state. Some buyers above certain income levels lose the subsidy entirely, while most buyers still qualify for a smaller credit.
Should I Keep My Current Plan Automatically?
Auto-renewal keeps your coverage active, but it doesn’t guarantee the best price. Compare this year’s options before your plan renews, since premiums and subsidy amounts both shifted for 2027.
What Happens if I Estimate My Income Wrong?
Underestimating your income can mean repaying part of your subsidy at tax time. Overestimating it means you pay more upfront than necessary, though you get the difference back later as a tax credit.
Final Thoughts
None of this means you did anything wrong by buying coverage on your own. Enhanced subsidies disappeared, premiums jumped, and the next open enrollment period brings another round of higher numbers. The one thing worth doing before November 1 is pulling up your actual renewal notice. Compare it against the full Marketplace, plan by plan. A few minutes of comparison now can save money over the next twelve months. That matters even more if your income shifts with a side hustle or freelance work.
