Can we use 2017 HSA to pay medical expenses from Dec 2016?
We had a HDHP with an HSA in 2015. In 2016, we again had a HDHP but not the HSA because the company did not offer an HSA. In Dec 2016, my daughter needed surgery. I used the remaining money in the HSA from 2015 to pay for a portion of her surgery. Now in 2017, we again have a HDHP with an HSA. Can I use the 2017 HSA to pay the remainder of her medical expenses from Dec 2016?
