Deductions & credits

"You can only take a tax deduction for an expense you paid with already-taxed money.  Money you already paid tax on. "

 

With an HSA, I contribute $3600 and then deduct that amount from my taxes.  So the money going into my HSA essentially has not been taxed...  From that HSA account, I pay medical bills and then deduct what I paid.  So the money going in is not taxed and medical withdrawals are not taxed.  I don't get why payments from an HRA account are not deductible...

(I know your right...  I just don't get why it's different...)
