The #1 2027 Open Enrollment Mistake High-Income Earners Make: Auto-Renewing at Full Price
Every December, millions of marketplace enrollees do absolutely nothing — and the system “helpfully” renews them into next year’s plan automatically. For subsidized households, that’s usually fine. For high-income earners in 2027, auto-renewal is the single most expensive mistake you can make during open enrollment.
Here’s what auto-renewal actually does to your coverage and your wallet in 2027, why full-price renewals have spiked, and the 10-minute comparison that could save you thousands.

What Auto-Renewal Actually Does in 2027
When you don’t take action during open enrollment, HealthCare.gov (or your state exchange) automatically re-enrolls you in the 2027 version of your current plan — or, if your insurer discontinued it, maps you to the “most similar” available plan. Sounds convenient. Here’s what it doesn’t do:
- It doesn’t re-check whether your plan is still a good deal. Premiums, deductibles, and networks all change year to year. The plan that was competitive in 2026 may be wildly overpriced in 2027.
- It doesn’t re-optimize your subsidy. Your 2027 advance premium tax credit is recalculated from your last application on file. If your income changed — a good year, a raise, a spouse’s new job — the auto-renewed subsidy amount could be wrong in either direction. Too high, and you’ll owe the difference at tax time (more on that below). Too low, and you’re overpaying all year.
- It doesn’t warn you about network changes. Insurers quietly narrow networks every year. Your doctors may have been in-network in 2026 and out in 2027, and auto-renewal won’t tell you.
- It doesn’t consider that you might not need the marketplace at all. This is the big one for high earners. The marketplace has no idea you now earn too much for subsidies, or that you’d qualify for a private underwritten plan at half the price. It just renews you.
Why Full-Price Renewals Spiked After Enhanced Subsidies Expired
From 2021 through 2025, enhanced ACA subsidies (from the American Rescue Plan and Inflation Reduction Act) capped marketplace premiums as a share of income and extended help well above the old 400% poverty-level cliff. Millions of middle- and upper-middle-income households got meaningful subsidies.
Those enhanced subsidies expired after 2025. For 2026 and 2027, the old rules are back: subsidies phase out entirely above 400% of the federal poverty level — $63,840 for a single person and $132,000 for a family of four in 2027 (per the 2026 federal poverty guidelines).
The result: a self-employed household earning $150,000 that paid $400/month after subsidies in 2025 might now face $1,400–$1,800/month at full price for the same plan in 2027 — and auto-renewal will happily sign them up for it without a second thought.
Making it worse, the repayment caps that used to limit how much excess subsidy you had to pay back at tax time were eliminated starting with the 2026 plan year. If auto-renewal assigns you a subsidy based on stale income data and you end up earning more, you now owe back every dollar — no cap, no mercy. (We’ll dig into this in our subsidy payback post.)
The 10-Minute Comparison Before December 15
If you currently have a marketplace plan and earn too much for meaningful subsidies, spend ten minutes on this before the December 15 deadline for January 1 coverage:
Minute 1–3: Pull your renewal notice. Your insurer is required to send an updated premium and benefit summary for 2027. Find the new monthly premium at full price and the deductible. Write both numbers down.
Minute 4–6: Price the private alternative. If you have no major health conditions, get a quote for a private off-exchange plan. These are medically underwritten PPOs available year-round, and for healthy applicants they typically run about half the cost of a full-price marketplace plan. You need to see this number side by side with your renewal — most people never do, and it’s the comparison that changes everything.
Minute 7–8: Check the real differences. Price isn’t the whole story. Compare networks (private PPOs often have broader national networks than marketplace HMOs/EPOs), deductibles, and how each handles your income. Private plans don’t do subsidy reconciliation — what you pay is what you pay, regardless of whether you have a banner year.
Minute 9–10: Check the average costs for context. If your renewal quote is way above average for your age and area, that’s a signal the market has moved and your plan hasn’t kept up.
What Smart High Earners Do Instead
The pattern we see every open enrollment among self-employed clients who’ve figured this out:
- They treat the renewal notice as a starting bid, not a final answer.
- They get a private underwritten quote at the same time they review marketplace options — not after they’ve already renewed.
- If they qualify health-wise and the math favors private (it usually does at full price), they switch — often keeping better doctors and paying substantially less.
- If someone in the household has a significant pre-existing condition, they stay on the marketplace plan, because ACA plans can’t consider health status and private plans can.
Auto-renewal exists to prevent coverage gaps for people who’d otherwise fall through the cracks. That’s a worthy goal. But if you’re a high earner with options, letting an algorithm choose your health insurance for 2027 is like letting your GPS pick your restaurant — technically functional, rarely what you’d actually want. Take the ten minutes. Your January self will thank you.
