40 Days Until 2027 ACA Open Enrollment — A Week-by-Week Florida Countdown

Quick version: Florida's 2027 Open Enrollment runs November 1, 2026 through January 15, 2027. December 15 is the deadline for a January 1 effective date; anything selected December 16 through January 15 starts February 1. The big change this year is not the window — it is the money. The enhanced pandemic-era subsidies expired December 31, 2025, so the 400% federal poverty level cliff is back, and premium math looks very different than it did last year.

Below: the exact dates, what changed, and a week-by-week prep list you can start today.

The 2027 Florida Open Enrollment timeline

What actually changed for 2027

The window is the same. The money is not.

The enhanced premium tax credits originally passed under the American Rescue Plan and extended by the Inflation Reduction Act expired on December 31, 2025. For 2027 coverage, we go back to the pre-2021 subsidy structure. Two practical consequences:

• The 400% federal poverty level cliff is back. Using 2026 poverty guidelines, that cliff sits at roughly $63,840 for a single filer and about $132,000 for a family of four. Households above the cliff receive no premium tax credit at all — they pay the full sticker price.
• People between roughly 150% and 400% FPL still qualify for a subsidy, but the required contribution as a percentage of income has climbed back to the pre-2021 schedule. Most Floridians in this range will see their monthly premium go up, though it's often still very affordable.

The bigger the household and the higher the income, the more Open Enrollment 2027 is a tax-planning exercise as much as a plan-shopping exercise. If your projected 2027 MAGI is $60,000 – $70,000 as a single filer, or $125,000 – $140,000 as a family of four, you are sitting right on the cliff — and a few thousand dollars of income difference can swing your annual premium by five figures.

The week-by-week countdown

Here is the exact schedule I'm walking Palm Beach County clients through between now and November 1. If you follow this, you will not be scrambling in early December when everyone else is.

This week (September 21 – 27): Project 2027 income

• Pull your last two pay stubs plus your 2025 return (or 2024 if you extended)
• Estimate your 2027 household MAGI — wages, self-employment, rental, capital gains, Social Security, IRA distributions
• If you're within $5,000 of the 400% FPL cliff, flag it and call your CPA — HSA contributions, retirement contributions, and timing of income can move you off the cliff legitimately
• If you're self-employed, remember your 100% self-employed premium tax deduction on Schedule 1 offsets your projected income (see the self-employed health insurance page for the full mechanics)

Week of September 28 – October 4: Inventory your care

• List every doctor you actually saw in 2026 — primary care, specialists, dentist, optometrist, mental health
• Write down all prescriptions (name, dose, frequency)
• Note any planned procedures, tests, or specialist visits for 2027 (colonoscopy, joint replacement, MRI follow-ups)
• Palm Beach County residents: confirm your preferred hospital — Bethesda, JFK, Wellington Regional, Palms West, Jupiter Medical, PBG Medical, Good Sam, or Boca Regional — every network handles them differently

Week of October 5 – 11: Watch for renewal notices

• Florida Blue, Aetna, Humana, UnitedHealthcare, and BCBS FL start mailing renewal notices in early October
• Look for a "notice of plan change" — this tells you if your current plan is discontinued or restructured
• Check the "benchmark plan" language — your subsidy is tied to the second-lowest-cost Silver plan in your county, and that plan changes almost every year
• Set aside 30 minutes for a review call (see the how-to-verify-your-doctor guide for the exact steps)

Week of October 12 – 18: Rate preview

• 2027 rates are typically posted by mid-October — the sooner you see real numbers, the better your decisions
• Compare your 2026 total cost (premium + deductible + expected out-of-pocket) to the 2027 equivalent — do not compare on premium alone
• If you're getting close to Medicare (turning 65 in 2027), review the early-retiree bridge coverage page and plan the Medicare handoff carefully

Week of October 19 – 25: Lock in an enrollment appointment

• The first two weeks of November are the busiest agent windows of the year — book early
• Prepare your documents: driver's license, Social Security numbers, 2025 tax return, income projection, doctor/prescription list
• If you're on the subsidy cliff, do a final tax-strategy conversation with your CPA

Week of October 26 – November 1: Ready to file

• Confirm your HealthCare.gov login works — password resets take 24 hours if the account is locked
• Have autopay information ready (payment must be received to activate coverage, not just enrollment)
• On November 1, enroll — don't wait for December. Early enrollees get the shortest hold times and the least frantic advice

Common Open Enrollment mistakes I see every year

1. Auto-renewing without checking

HealthCare.gov auto-renews you into the same plan (or a comparable one). Networks, formularies, and prices change every year, and a plan that was great in 2026 is very often no longer the best fit for 2027. Auto-renewal is convenient. It is almost never optimal.

2. Underestimating income

Your subsidy is based on projected 2027 income. Underestimate and you get a bigger monthly subsidy — and owe the IRS money back at tax time. Overestimate and you get less help than you should. Aim for accurate, not optimistic. Self-employed folks especially: your business is bumpy but your subsidy math is not.

3. Ignoring the subsidy cliff

If your household income lands even $1 above the 400% FPL cliff ($63,840 single / $132,000 family of four, 2027 coverage), you lose the subsidy entirely. There are legitimate ways to plan around this — HSA contributions, traditional 401(k) elections, Solo 401(k) contributions for the self-employed. The time to plan is before December 31, 2026, not April 15, 2027.

4. Losing a doctor mid-year and not knowing it

Networks change January 1 without warning. That specialist you love at JFK or Jupiter Medical could be out of network on your renewal plan even if your carrier stays the same. Verify in October, not February.

Who this checklist matters most for

• Self-employed and 1099 professionals — the biggest group with income control levers. See the 1099 contractor page.
• Families of 3+ approaching the cliff — the cliff hits families harder than singles because the dollar amount is larger.
• Early retirees 55-64 — you have income flexibility (IRA vs. taxable withdrawal timing) that most working households don't. Use it.
• Anyone with a big income change in 2026 — new job, business sale, retirement, Roth conversion, home sale.
• Small business owners on the individual market — worth exploring an ICHRA before locking in another individual plan.
