ACA Open Enrollment Is Changing for 2027

July 7, 2026

Here's What You Need to Know


If you have a health plan through the ACA Marketplace, your renewal or enrollment window is getting shorter for the 2027 plan year. The sign-up period now ends in December, and the old February start date is going away. Read on for what changed and why it matters for you.



The Enrollment Window is Shorter


For the last few years, most people had until January 15 to enroll or renew in a Marketplace plan. Starting in 2026, open enrollment will end one month earlier, on
December 15 in many states. In most states, sign-ups still open on November 1, 2026.


Two states start even earlier. In Idaho, open enrollment begins on October 15, and in Georgia it begins on October 19.



Enrollment Periods at a Glance


Here's the national schedule for states that use HealthCare.gov, which covers most of the country:


Enrollment Start: November 1, 2026
Enrollment End
: December 15, 2026
Coverage starts
: January 1, 2027



Known Enrollment Timeframes for Some State-Run Exchanges


Some states run their own exchanges and set their own deadlines. State-run exchanges can extend enrollment later than December 15, but not past December 31. Here are the 2026 ranges announced so far (for 2027 coverage). Dates can still change, so confirm with your state's marketplace before you enroll.


States starting early:


Idaho: Oct 15 – Dec 15, 2026

Georgia: Oct 19 – Dec 15, 2026


Extended deadlines:


Nov 1 – Dec 23, 2026: Massachusetts

Nov 1 – Dec 31, 2026: CA, CO, CT, KY, MD, MN, NV, NM, OR, RI, VA, WA


If your state is not listed here, you likely follow the national schedule above, with a November 1 to December 15 window.



No More February 1 Start Date


In past years, if you signed up after mid-December, your coverage started February 1. That option is going away. All plans selected during open enrollment will take effect on January 1.



What You Can Do Now


Mark your calendar for November 1, 2026. Know your state's exact deadline. And if you have questions about your plan or your options, we are here to help. Acting early gives you time to compare and helps you avoid a coverage gap.

Imagine suddenly being unable to work due to a serious illness or injury. With no paycheck coming in, how would you cover your rent, groceries, or medical bills? Unfortunately, many Americans haven’t prepared for that possibility—and could face serious financial stress if they need long-term time off but lack income protection. Why This Matters  Disability insurance (including short-term and long-term plans) is designed to replace part of your income if you can’t work due to illness or injury. Yet coverage remains out of reach for many: According to the latest disability insurance industry analysis , just 40% of working-age adults carry disability coverage. For employer-sponsored plans specifically, the U.S. Bureau of Labor Statistics reports that only 34% of private-industry employees had access to long-term disability insurance in 2024. These statistics demonstrate a significant protection gap: even among those with health insurance, a large share lack disability coverage. At the same time, long-term disability can last months or years —not just weeks. The average long-term disability lasts about 35 months , while about 30% of Americans couldn’t handle an unexpected $400 expense without outside help. That combination of low coverage and high risk can spell financial trouble.
