Most states stuck to the hard deadline of January 31st, 2016, but a few states are allowing those who signed up (but didn’t enroll) a few extra days to enroll.
If you signed up for the health insurance marketplace, but couldn’t finish the enrollment process in time, try finishing the process now (obviously the further away we get from January 31st, the less likely it is you’ll be able to do this).
Only a few states extended open enrollment this year. Even if your state didn’t, you should still ensure the enrollment process has been completed correctly and double check that your first payment was submitted.
UPDATE FOR OPEN ENROLLMENT 2017: 42 states extended the December 15th, 2016 deadline to December 17th or 19th, 2016. Extensions were generally limited this year, but do check with your state.
