Deadline to provide supporting documentation after SEP enrollment

💡 If you became self-employed after leaving a W-2 job, your last day of employer coverage is your qualifying event — not the day you started freelancing. Enroll in an ACA plan within 60 days of your employer coverage ending. Many newly self-employed individuals miss this and assume they need to wait for Open Enrollment.

Moving within the same coverage area does NOT trigger a SEPMoving to a new county or state triggers an SEP because your plan network changes. Moving across the street within the same coverage area does not. If you move within your current plan's service area, you don't have a qualifying event based on the move alone.

Frequently asked questions

What is a Special Enrollment Period for health insurance?

A Special Enrollment Period (SEP) is a window outside of Open Enrollment when you can sign up for or change an ACA Marketplace plan. SEPs are triggered by qualifying life events such as losing employer coverage, marriage, birth, or moving to a new state. Most SEPs last 60 days from the qualifying event.

What qualifies as a life event for health insurance?

Qualifying life events include: losing employer or group coverage, turning 26 and aging off a parent's plan, getting married or divorced, having or adopting a child, moving to a new coverage area, losing Medicaid/CHIP eligibility, gaining citizenship, or being released from incarceration.

How long do I have to enroll after a qualifying event?

You have 60 days from the date of the qualifying event to enroll in an ACA Marketplace plan. After 60 days, you must wait until the next Open Enrollment period (November 1 – January 15) unless you experience another qualifying event.

Does becoming self-employed qualify for a Special Enrollment Period?

Becoming self-employed alone is not a qualifying event. However, if you left a job that provided health insurance to become self-employed, the loss of that employer coverage IS a qualifying event — giving you 60 days from your last day of coverage to enroll in an ACA plan.
