During the year 2017, from the 31st of May till the 19th of June I didnt have health insurance coverage for my entire family. This was due to a job change.
What are my penalties for the gap period during which I didnt have Health insurance coverage for me and my family?

There was no gap.  You had coverage in May and in June

I understood something today. Thank you. All these days, I was thinking that there was a gap in my insurance spanning 19 days. As my new employers insurance didn’t start till I started on the 19th June. Thank you again

You are entitled to an exemption if the time is less than 3 months. Short coverage gap (code “B”).

You generally can claim a coverage exemption for yourself or another member of your tax household for each month of a gap in coverage of less than 3 consecutive months. If an individual had more than one short coverage gap during the year, the individual is exempt only for the month(s) in the first gap. If an individual had a gap of 3 months or more, the individual isn't exempt for any of those months.

For example, if an individual had coverage for every month in the year except February and March, the individual is exempt for those 2 months. However, if an individual had cover­-age for every month in the year except February, March, and April, the individual isn't exempt for any of those months.

 An individual is treated as having coverage for any month in which he or she has coverage for at least 1 day of the month.
