How to Read Your 2027 ACA Renewal Notice in 5 Minutes
A letter about your health plan just showed up, and it's full of plan IDs, dollar amounts and fine print. Your 2027 ACA renewal notice is the most important piece of mail you'll get this fall, and most people skim it and toss it. Here's how Michigan families can read it in five minutes and catch the problems before they cost money.
Minute 1: Know which letter you're holding
Most people get two letters this time of year, and they do different jobs.
- The Marketplace letter (from HealthCare.gov) tells you if you'll be automatically re-enrolled for 2027, and whether it's the same plan or a different one.
- The insurance company letter explains your plan's 2027 price, benefits and any changes. If your plan is ending, this letter says so.
HealthCare.gov will automatically re-enroll most people so there's no gap in coverage. That's a safety net, not a recommendation. "Auto-renew" just means the system picked something for you.
Takeaway: Find both letters and keep them together. You'll need both for the next four minutes.
Minute 2: Find your new monthly price, after savings
Look for the 2027 monthly premium and, if you get help paying, the tax credit applied to it. The number that matters is what you pay each month after savings.
Premiums are rising for 2027. Insurers proposed a median increase of about 15%, according to KFF's August 2026 analysis. Your savings may rise too, but not always by the same amount. Two neighbors on the same plan can see very different changes.
Takeaway: Write down this year's monthly cost next to next year's. If the gap surprises you, that's your sign to compare.
Minute 3: Check whether it's still your plan
Read the plan name on the 2027 letter and compare it to the plan on your current insurance card. If you see words like "discontinued," "no longer offered" or "similar plan," your plan is ending and you've been matched with a replacement.
This matters more than usual this year. Insurers are pulling out of the individual market in more than 20 states, and hundreds of thousands of plans end December 31. HealthCare.gov says a replacement may come from your same company, or from a different company if yours has no similar plan. A replacement can have a different doctor network or drug list, even if the name looks almost the same.
Takeaway: If the plan name changed at all, check your doctors, your hospital and your prescriptions before January 1.
Minute 4: Look past the premium to the deductible and out-of-pocket max
Find two more numbers: the deductible (what you pay before the plan starts sharing costs) and the out-of-pocket maximum (the most you'd pay in a year for in-network care).
For 2027, the out-of-pocket max can go as high as $12,000 for one person, up from $10,600 in 2026 (healthinsurance.org). A plan can keep the same monthly price and still raise your deductible. That doesn't show up until you need care.
Takeaway: If your deductible or out-of-pocket max went up, ask yourself one thing: could I cover that in a bad year?
Minute 5: Check the income your savings are based on
Your savings for 2027 are based on what you expect to earn in 2027, not last year. If you don't update it, HealthCare.gov says you could get less savings than you qualify for, or more, and have to pay it back at tax time.
This is a big deal if you're self-employed, got a raise, changed jobs or added someone to your household. The extra pandemic-era savings ended after 2025, so for 2027 there's no help above 400% of the poverty level. For one person that's about $63,840 (healthinsurance.org). Being just over or under that line can change your bill by hundreds a month. Self-employed? Here's how to estimate your 2027 subsidy from net income.
Takeaway: Update your 2027 income estimate when Open Enrollment opens November 1, before you pick a plan.
What to do next, and by when
- November 1: Open Enrollment opens. Log in, update your income and household, and compare plans.
- December 15: Pick your plan by this date so coverage starts January 1.
- January 15: Last day to enroll or switch. Enroll after December 15 and coverage starts February 1.
Even if you were auto-renewed, you can still change plans until January 15. Missing December 15 doesn't mean waiting a year. It means a one-month gap.
