Open enrollment runs November 1 through January 15. Miss it and you generally wait until next November. A reminder set before the window opens gives you time to compare plans, not just renew whatever you had last year.
Done in seconds. No sign-up required.
The ACA Marketplace has two deadlines inside the enrollment window, and most people only know about one. Knowing both could be the difference between January coverage and a six-week gap.
| November 1 | Open enrollment starts. Plans go live, subsidies calculable. Best time to compare. |
| December 15 | Deadline for coverage starting January 1. Miss this and coverage starts February 1. |
| January 15 | Final deadline. After this, the window closes. Coverage starts February 1. |
| After Jan 15 | No enrollment until next November 1 — unless you have a qualifying life event. |
Note: some state-run exchanges have different end dates. California runs through January 31. Check your state exchange for exact deadlines.
One missed deadline can mean months without coverage.

ACA open enrollment calendar
Open enrollment is one of those tasks that feels like it can wait until tomorrow. November arrives with the holidays, then Thanksgiving, then December is gone before you've looked at a single plan. The deadline isn't on a bill, a notification, or anything your insurance company sends unprompted. It just passes.
The other trap is auto-renewal. It feels like a safety net but it's actually a reason not to pay attention. Your plan gets renewed, you're technically covered, and you never compare what else was available. Subsidies change. Premiums change. A 20-minute review in November can save hundreds of dollars a year. Most people skip it.
A reminder before November 1 solves both problems. It arrives when the window is open, not after it closes.
The best time to set your open enrollment reminder is not November. It's now. Set it once, and you'll get emails days before the window opens with enough lead time to actually compare plans before rushing to meet a deadline.
October 15 gives you two weeks to review plans before November 1. Or use November 1 itself if you just want to make sure the window doesn't close on you.
You'll get notified days before your reminder date. Not a calendar alert you dismiss and forget — an email that follows up until you've acted on it.
Once you've enrolled or made your decision, mark the reminder done. If you haven't acted, BoldRemind follows up so it doesn't quietly disappear.
The consequences of missing open enrollment are real and specific.

ACA Marketplace open enrollment runs November 1 through January 15 each year. December 15 is the mid-deadline — enroll by then for coverage starting January 1. Enroll between December 16 and January 15 and coverage starts February 1. Employer plans have separate windows set by each company.
If you miss the January 15 ACA deadline, you generally cannot enroll until the next November 1 — a wait of up to 10 months. You may qualify for a Special Enrollment Period if you have a qualifying life event like losing a job, getting married, or having a baby. Otherwise, you wait.
Set it for at least two weeks before November 1 — the start of open enrollment. That gives you time to research plans before committing. If you just want to make sure you don't miss the deadline, set it for October 15. Missing November 1 doesn't lock you out, but starting late limits your options.
No. ACA Marketplace enrollment runs November 1 through January 15 for individual and family plans. Employer-sponsored plan enrollment windows are set by each company, typically in October or November, but the exact dates vary. Check with your HR department for your company's specific window.
Only if you have a qualifying life event that triggers a Special Enrollment Period. Common triggers include losing other coverage, getting married or divorced, having a baby, or turning 26 and aging off a parent's plan. You typically have 60 days from the event to enroll.
Auto-renewal keeps you covered, but you may be paying more than you need to. Subsidies, premiums, and plan options change year to year. Reviewing during open enrollment takes 20 minutes and could save hundreds annually. A reminder before November 1 gives you time to compare, not just renew.
Free. No account. Takes 30 seconds. You'll get notified before November 1 so you have time to compare plans and enroll — not a panicked last-minute scramble.
