Many people realize they have made errors on returns after the returns have been mailed.
If the errors are in arithmetic, the service center will usually correct them. If forms or schedules were left out, the service center will request additional information from you. You need not file an amended return. However, if you find that you did not report some income, you claimed deductions or credits you should not have claimed, you failed to claim some deductions or credits you are entitled to, or you should have used a different filing status, you should file an amended return. If you file Form 1040X to claim an additional refund, you should wait until after you have received the refund from the original return to avoid a possible delay in processing.
