2027 Open Enrollment Deadlines for People Switching from Marketplace to Private Insurance
Thinking about leaving your marketplace plan for a private off-exchange plan in 2027? You're not alone — with subsidies expiring for higher earners, this is the biggest switching season in years. But switching isn't just picking a new plan. The timing matters, because a misstep can leave you double-paying for a month or, worse, briefly uninsured.
Here's the deadline map and the exact sequence to switch cleanly.

The Dates That Matter
Federal open enrollment runs November 1, 2026 through January 15, 2027. Two dates inside that window do the heavy lifting:
- December 15, 2026 — enroll by this date for coverage starting January 1, 2027. This is the date that matters for switchers.
- January 15, 2027 — the final deadline; coverage starts February 1, 2027.
(A handful of state-run exchanges have slightly different windows, so confirm your state's dates — but December 15 for a January 1 start is the standard nearly everywhere.)
Here's the key difference from a straight marketplace renewal: private off-exchange plans are available year-round. You're not locked to open enrollment to buy one. But if you want your new coverage to start January 1 — no gap, no overlap — you should still work to the December 15 timeline.
Why Switchers Need a Plan (Not Just a Date)
If you're simply renewing a marketplace plan, the exchange handles the continuity. When you're moving from the marketplace to a private plan, you're coordinating two separate systems that don't talk to each other. Three things can go wrong:
- A coverage gap. Your marketplace plan ends December 31 and your private plan doesn't start until February 1. One bad January accident in that window is financially catastrophic.
- Double-paying. Both plans active in January because you never terminated the marketplace one properly.
- Subsidy reconciliation surprises. If you received advance premium tax credits in 2026, the IRS reconciles them at tax time — and with repayment caps now eliminated, owing the full excess back is a real risk if your income came in higher than estimated. Switching for 2027 doesn't erase 2026's reconciliation, so keep your records clean.
None of these are hard to avoid. You just need the right sequence.
The Switch Sequence: Step by Step
Step 1 — Early November: get your private quote and apply. Don't wait until December. Apply for the private off-exchange plan first, while your marketplace coverage is still safely in force. Remember these plans are medically underwritten — applicants generally need to be in relatively good health to qualify, and approval isn't instant. Give yourself runway in case the underwriter asks follow-up questions.
Step 2 — Get your approval in writing. Don't cancel anything until your new plan is approved and you have a confirmed January 1 effective date. This is the golden rule of switching. Until that confirmation exists, your marketplace plan is your safety net.
Step 3 — By mid-December: terminate your marketplace plan effective December 31. Log into your exchange account and end your coverage — don't just stop paying premiums. Simply not paying can create a messy termination, lingering bills, and confusion about whether advance credits kept flowing. A clean voluntary termination effective 12/31 is what you want.
Step 4 — Confirm the handoff. In late December, verify two things: your marketplace plan shows a December 31 end date, and your private plan shows a January 1 start date. Then you're done.
What If You Miss December 15?
You have options, just less tidy ones. Enroll in the private plan anyway — since off-exchange plans are available year-round, you can start one February 1 or March 1. Then terminate the marketplace plan to match. You'll pay the marketplace premium for the overlap months, which isn't ideal, but it's far better than a gap.
What you should not do is go uninsured while you "figure it out." One emergency room visit without coverage can cost more than a full year of premiums.
A Note on Why You're Switching
Let's name the reason, because it affects your decision: for 2027, the enhanced subsidies are expiring and the 400%-of-poverty-level income cap is back ($63,840 single / $86,560 couple / $132,000 family of four, per 2026 poverty guidelines). If your household is over the line, your marketplace plan just got dramatically more expensive — while the private plan next to it didn't change at all.
These private off-exchange PPO plans usually cost almost half as much as a full-price marketplace plan with no subsidies, as long as there are no major health conditions. Many run on national PPO networks. They're medically underwritten and aren't ACA-equivalent coverage — no pre-existing condition coverage like marketplace plans — so they're not for everyone. But if you're healthy and subsidy-ineligible, the math is the math.
Your November Action Plan
- Week of Nov 1: Request private off-exchange quotes; compare against your 2027 marketplace renewal price.
- Mid-November: Apply for the private plan. Keep your marketplace plan untouched.
- Early December: Receive approval; confirm January 1 effective date.
- By Dec 15: Terminate marketplace coverage effective Dec 31. Verify both dates.
Four steps, six weeks, zero gaps. That's a clean switch.
