Will the IRS make someone pay for claiming a child that one parent keep for 9 months?

Answer 1

If you are the parent that was entitled to claim the child, then file a paper return. The IRS will send a notice to both parties that the child was claimed twice and that someone needs to file an amended return. They will also request that proof of being entitled to claim the child be submitted to them. This can be school records,Dr records, Copy of a lease recognizing that the child lives at the address of record.
This will delay the processing of your return, until the IRS determines who is actually eligible to claim the child.
If one party receives a refund that they were not entitled to they will have to pay the monies back with penalties and interest. and their future returns will be subject to reviews and audits

Answer 2

DID THE OTHER PARENT ALSO CLAIM THIS CHILD ON THEIR TAXES AS A DEPENDENT? IF SO THEN THE IRS WILL SEND OUT A PROOF OF HEAD OF HOUSEHOLD FORM THAT REQUIRES CERTAIN PROOF THAT YOU WERE THE MAJOR SOURCE OF THAT CHILDS WELL CARE AND SUPPORT . THE ONLY PARTY ALLOWED TO CLAIM THE CHILD IS THE PARTY WHO WAS AWARED THE CHILD AS A DEPENDENT ON THE FINAL DIVORCE DECREE. IF ANY NEW ARRANGEMENT BETWEEN THE PARENTS ARE MADE AFTER THE DIVORCE IS FINAL A MODIFICATION OR A NOTORIZED CHANGE OF RECORD DOCUMENT SHOULD BE OBTAINED AND OR FILED WITH THE COURT IN ASSURANCE THAT YOU ARENT IN VIOLATION OF SUCH THAT COULD ACCESS PENALTIES IN FILING WRONGFUL OR FRAUDULANT INFORMATION.
