Deductions & credits

I can claim this direct contribution as deductible during tax filing but will I save the taxes same way as I would have saved through paychecks?   If you are covered under a HDHP then you can make HSA contributions with after tax money and get an adjustment on your return. 

 

 

I heard that I won't be able to save FICA taxes. Is that correct?  That is correct, on your return you only save fed (and if allowed) state taxes.
