When should you amend your tax return and when is it required that you do so? You need to file one with the IRS each year if your income is over the requisite level, which depends on your age and filing status.
In fact, you can be prosecuted for failure to file (a misdemeanor) or for filing falsely (a felony). If you are thinking about amending your tax return, ask yourself: Was the one I filed accurate to my best knowledge when I sent it in?
