If you don't have a nice desk reference for this stuff (get one), the IRS has an interactive tax assistant (ITA) for filing status here:

There are several other ITAs so you should bookmark this page:

You'll get a much faster and more accurate answer than asking a bunch of strangers on the Internet. 🙂
