If you reported the wrong amount of alimony, and the difference is $200, you should file an amended return to correct it. This would be true whether you are the payer or the receiver.
Which one of you reported the wrong amount? You don't file an amended return because the amount you reported was different from what your ex reported. You file an amended return if the amount you reported was wrong. If you reported the correct amount and your ex reported an incorrect amount, you should not amend your return. In that case, your ex should amend his or her return to correct the amount.
An amended return has to be filed on a special form, Form 1040X. It cannot be e-filed. You have to print it, sign it, and file it by mail. It takes the IRS up to 16 weeks to process an amended return.
Don't file the amended return until your first return has been accepted and you have received the original refund.
If you will owe additional tax, or will have to pay back part of your refund, you should file the amended return before April 17 to avoid possible penalties and interest.
