I have a HSA opened in June with a $1k opening balance. Sometime in August, I had a medical bill totaling $3k and I absent-mindedly paid for it out of my regular checking account.
Assuming I have all my receipts, can I now transfer another $3k into my HSA and then withdraw it back to my regular checking account and have that outflow from my HSA count towards the medical expense? Or am I only allowed to pay for a medical expense if the money directly came from my HSA at the time of payment?
Also, there were some other qualifying medical expenses in April (before I opened the HSA). Again, assuming I have receipts for these, can I adjust that expense against my HSA balance?
