Open enrollment for 2021

The Affordable Care Act (ACA) open enrollment period to sign up for coverage that starts on Jan. 1, 2021 runs from Nov. 1, 2020 through Dec. 15, 2020.

  • Jan. 15, 2021 is the last day to sign up for coverage that begins Feb. 1, 2021.
  • If you don't enroll in a 2021 health insurance plan by Jan. 31, 2021, you will not be able to enroll in a 2021 plan unless you qualify for a Special Enrollment Period.

Contributions to Flexible Spending Accounts

The ACA introduced an annual contribution cap limit of $2,500 for Flexible Spending Accounts (FSA). Contributing to an FSA through your employer's plan allows you to divert pre-tax income, resulting in lower taxable income for a tax year. Of course, you must use the money you withdraw from your FSA only for qualified health-related expenses to maintain its tax advantaged treatment.

Qualifying life events

You can bypass date requirements for healthcare reform open enrollment periods if you experience a life event leading to a change in healthcare coverage.These life events can include:

  • Losing health care coverage, such as through a change of employment status
  • Changes to your marital status
  • The birth of a child
  • If you’re covered under your parents' plan but reach your 26th birthday

Changes to income may alter your eligibility for health coverage subsidies for existing qualified coverage. New U.S. citizens are also eligible for enrollment at any time under qualifying life event provisions. You can apply for Medicaid or the Children's Health Insurance Program at any time through a year.

Open enrollment for future years

Future open enrollment periods are expected to continue to be late in fall to early winter. Penalties for remaining uninsured are either a flat fee per person in a household or a percentage of household earnings, whichever is highest.

  • These penalties remain in affect through 2018 and will no longer be assessed beginning in 2019.
  • The penalty rates increased each year until 2016, after which penalties have been indexed with inflation.

If penalties are not paid with your tax return, they can be withheld from tax refunds in the current year or, if a taxpayer has a balance owing, from refunds in future years.

  • Interest is charged on unpaid penalties.
  • Unlike other tax amounts owing, the IRS can't impose liens or other criminal penalties for failure to pay these penalties.
