Do I get taxed if I make a withdrawal from my 401k to pay for my medical bills?

[VolvoGirl]

Yes.  But if you are under 59 1/2  you might avoid the 10% Early Withdrawal Penalty for Medical Expenses.  If you take a Withdrawal it is taxable on your return and may push you into a higher tax bracket and more income can reduce or eliminate some credits you may qualify for.  So be careful.

The amount of unreimbursed medical expenses in excess of 7.5% of your AGI paid by your early withdrawal can be excluded from the 10% early withdrawal penalty but not from ordinary income taxes.
