Yes, you would want to
attach any forms to your return that show income tax withheld; however, if your
1099’s doesn’t show any income tax withheld, you don’t need to attach them. Make
sure your sign your return because it will not be valid unless your signature
is on it. The IRS states, “For supporting statements, arrange them in the same order
as the schedules or forms they support and attach them last. Attach a
copy of Forms W-2, W-2G and 2439 to the front of Form 1040.”
