HealthCare.gov will be your best bet to shop and compare options. Open enrollment starts 11/15 for policies taking effect 1/1. If you have a qualifying life event (moving, marriage, divorce, income change, lost coverage, birth, death, etc) you can enroll outside of the open enrollment times. If you include your income in the online tool, it will tell you what tax credits and cost sharing subsidies you're eligible for. Select a silver plan for the best cost sharing subsidies and tax credit situation if your income is between 100% and 250% FPL.
