When Will Coverage Start With Extended Enrollment? Generally, if you enroll before December 15th, your coverage starts January 1st. If you enroll after December 15th, your coverage will start February 1st, and if you enroll after February 15th, your coverage will generally start March 1st. With that said, some states that extend enrollment will have different rules and changes each year. For example, changes under COVID can cause exceptions to this as well. Please check the federal or state websites for details on when your coverage will start.

Where Can I find my state’s ObamaCare website? All state websites can be found on HealthCare.Gov’s home page. When you get to the site, you’ll get to pick your state. You’ll be taken to it if your state has its own exchange.

Other states may be subject to an extension in 2024. States with state-run exchanges can issue last-minute extensions, and the federal government can also issue an extension for all states using the federal marketplace.
