Can you refile your income tax?

Actually, you must...if your find an error, up or down, or such. It's no big deal. It's called an amended return. The form for individuals is called an 1040X. Its easy to complete...you really just need to show the changed item...what you oriignally reported it as, what it should have been and the difference. Not surprisingly, it them allows you to figure out if you owe more or if you get a refund.
