I would like to withdraw money from my 401k.I am 62 years old.how will I be taxed on my withdrawal

The amount of the withdrawal is treated as ordinary income for tax purposes. The admin will most likely withhold 20% for federal taxes - whether this is adequate depends on your tax bracket, which in turn deepnds on factors such as your total adjusted gross income, filing status, exemptions, and deductions. You may also owe state/local income tax, depending on where you live. The good news is that you will not owe any early withdrawalo penalty.

ebaines, as usual, has covered the topic thoroughly, so I have nothing to add.
