How do the benefits differ? What would you owe in out-of-pocket costs if you were to be injured or get seriously ill? How does that compare with your out-of-pocket exposure on the employer-sponsored plan? Are your doctors in the network of the individual plan? You'll want to carefully consider all of these things before switching, and keep in mind that you won't be able to rejoin your employer's plan until the next open enrollment window offered by your employer.
These plans meet all the requirements of the health care law, including covering pre-existing conditions, providing free preventive care, and not capping annual benefits. If you have one of these plans, you won’t have to pay the fee that people without coverage must pay through the 2018 plan year. (Note: Starting with the 2019 plan year (for which you’ll file taxes in April 2020), the fee no longer applies.)
