Additional Advice About Open Enrollment 2019

Below are a few additional points to consider.

  • In the past open enrollment in the federal marketplace HealthCare.Gov has been extended. Despite this, one should never count on extensions. We advise shopping early to avoid missing the official deadline. If things change, we’ll make sure to keep you updated.
  • If you qualify for cost assistance, think carefully about how much you take up front in Advanced Premium Tax Credits. Cost assistance is based on household income and family size as compared to the Federal Poverty Level. If you project your income inaccurately, you may end up owing back tax credits on form 8962 at tax time. This is especially true if you or a tax filer in your household gains or loses income. Medicaid and out-of-pocket assistance don’t require repayment.
  • We advise those looking for coverage to shop on their state’s official marketplace or (in states that use the federal marketplace). This will ensure shoppers know all their options regarding cost assistance and get a major medical plan that counts as minimum essential coverage. Shoppers can also contact an online or in-person broker (like the ones featured on our site) for help selecting a marketplace health plan or off-marketplace plan. In some cases, shoppers can also go directly to an insurer although this may require going directly to an insurer’s office, as insurers are encouraging shoppers to use the exchange. Learn more about shopping for private health plans outside the marketplace.
  • See also maximums and deductibles and HSA info for plans. An HSA is an excellent way to save tax dollars for those who have enough money to fund them.

BOTTOM LINE: Start your journey at Make sure you are not only signed up but enrolled in a plan by December 15th, 2018. This is the deadline for all states if you want coverage that starts by Jan 1st, 2019. We suggest paying careful attention to cost sharing and networks when shopping for a plan. When in doubt, a Silver Plan that qualifies for an HSA is typically a safe bet. Get more tips for shopping for getting the best health plan.
