Tax returns that can't be fixed for e-filing

Some tax returns can't be e-filed, no matter how hard we try. For example, if someone else claimed your child as a dependent and has already filed their return, the IRS won't let you e-file yours. Any time you are unable to e-file, you can always file your tax return by mail instead.
