You still have a bit more time to put money in your HSA for 2015. Thinkstock By Kimberly Lankford, Contributing Editor From Kiplinger's Personal Finance, March 2016 Can I still contribute to a health savings account for 2015? --M.S., AtlantaSee Also: 50 Ways to Cut Your Health Care Costs Yes. You have until April 18, 2016—the deadline to file your 2015 tax return—to make your 2015 contribution. You can contribute $3,350 for individual coverage or $6,650 for family coverage (plus $1,000 if you’re 55 or older) if you had an HSA-eligible health insurance policy on December 1, 2015. Otherwise, the size of your HSA contribution is based on the number of months you had the eligible coverage. If you had an HSA-eligible policy on December 1 but not for the entire year, you can make the full contribution but must keep an HSA-eligible policy for all of 2016 to avoid taxes and a 10% penalty for the extra months’ contributions.
