An amended tax
return generally allows you to file again to correct your filing
status, your income or to add deductions or credits you may have
Here are nine points
to know about amending your federal income tax return.
1. Use Form
1040X, Amended U.S. Individual Income Tax Return, to file an
amended income tax return.
2. Use Form
1040X to correct previously filed Forms 1040, 1040A or 1040EZ.
An amended return cannot be filed electronically, thus you
must file it by paper.
you do not need to file an amended return due to math errors.
The IRS will automatically make that correction. Also, do not
file an amended return because you forgot to attach tax forms

return, without regard to extensions.
