Hello All. So I got letter for EIC compliance to make sure that im doing them accurately so im being very cautious on all my eic returns. I have one today that i really didnt know which was the accurate way to file. So taxpayer 1 mother of 1 child she makes roughly 47,000 annually she supports and lives with her daughter. She also lives with taxpayer 2 which is her boyfriend and biological father of their child. He makes about $20,000 annually. Is it ok to put the child under the father since he would get the most back for EIC? or is that the wrong way to file for them? Im confused as to when to apply the tiebreaker rules if they mutually agree to let the parent claim the child to get the most back.
