I am about to complete my tax return and I just found out that I can make a personal contribution to my 2017 HSA account, since I haven't maxed it out, in order to get a higher refund for 2017.
My question is, the official deadline for making this contribution is 4/17/2018 and if I make this contribution tomorrow, is that good enough to claim it on my return? Are there any other things I should be aware of before doing this?
Thanks
