ACA requirements when travelling for more than 330 days [closed]

My wife and I are both U.S. citizens and plan on quitting our jobs and taking a year long trip around the world starting in September. That means we'd be without ACA health insurance for 4 month in 2016.

According to the IRS (https://www.irs.gov/affordable-care-act/individuals-and-families/questions-and-answers-on-the-individual-shared-responsibility-provision) if you travel abroad for more than 330 days it should be fine:

However, U.S. citizens who are physically present in a foreign country or countries for at least 330 full days during any period of 12-consecutive months are exempt from the individual shared responsibility payment for any month in the tax year that is included in that 12-month period.

Though when I have to file taxes for 2016 we'll be in the middle of those 330 days. Does anybody know how that'll work? Will I have to pay the penalty for 2016? Will I get that back in 2017 or just have to eat it? Is there some way of saying that we're currently abroad and plan on staying for >330 days?
