So my wife gave birth to our crazy little son Mid-Feburary 2016. I opened an HSA 3/1/16. I then started sending $ to my HSA as the medical bills started coming in (C-Section, so ~9k after insurance). I was planning to pull this money back out since I have ~9k of qualified expenses and could lower my AGI because I contributed to my HSA. We are planning to just barely max out our traditional IRA's this year, so leaving the money in there long term isn't the plan.
90% of the bills have a billed date of Mid-March; so were these incurred "after" I opened my HSA account? Or did opening my HSA account 10 days after the birth really cost me $1350 (15%tax rate*9000)?
(I do realize I cannot put 9k in the HSA this year)
