Do I owe tax any tax?

[greentea]

Hi,
I would like to know how do I check if I owe any federal tax in the past? How do I do it? I'd just like to make sure I don't owe any in my paying-tax history.
Thanks,
John

You can contact the IRS in several ways. One manner might be using the web site at IRS.GOV to find out all the information you are seeking. They also do list a toll free number.
