You need to be covered only by a High Deductible Health Plan to be eligible for an HSA (if your dad's plan is a HDHP, pay attention to MDM's post), but I certainly wouldn't choose to pay for insurance to get access to an HSA instead of getting free insurance (assuming your dad isn't paying any extra to cover you).
Apologies all, should of been more descriptive (I am learning this all now)
- I will not be a dependent anymore this year
- My dad's plan apparently is not HDHP according to him
- I have no other coverage other than my dad's plan (I currently have waived current employer coverage)
I do have the option of enrolling in my employer's HDHP plan and opening a HSA account. But as terran mentioned, probably wouldn't be worth it. Overall, if I needed to buy my own insurance right now or if dad had HDHP plan - the HSA would be a good idea. I believe in my specific case here, I'm not going to worry about it
-for now-.
Thank you all very much for your thoughtful replies!
