NY State
Couple has been separated since 7/2023. Wife would only allow visitation which didn't turn to overnights until November.
The wife didn't work or provide financially at all until she started working in October.
He is being told that she will most likely be able to claim both children. They don't have a court order and haven't even started divorce proceedings because they are trying to wrap up custody proceedings. I'm confused why he can't just go and file his taxes with no court order and financially providing all support for the first 9 months.
Can there be a legal repercussion to him filing married separately and claiming at least one if not both of the kids?
It depends on whether or not the couple is separated physically (living in different homes), when that started, and where the children primarily lived during the year. Under the IRS rules the parent with whom the children primarily lived is the parent who can claim the children. It does sound, from your description, that the children primarily lived with the mom, so odds are she is the one in whose favor the IRS would rule if there is a duplicate claim. Who provided the most financial support doesn't kick in unless both parents lived an equal amount of time with the children. Here are the tiebreaker rules:
TieBreaker Rules
Sometimes a child meets the rules to be a qualifying child of more than one person. The following rules must be applied to determine who can claim the child as a qualifying child. Under the tie-breaker rule, the child is treated as a qualifying child:
- The parent, if only one of the persons is the child's parent,
- The parent with whom the child lived the longest during the tax year, if two of the persons are the child's parent and they do not file a joint return together,
- The parent with the highest AGI if the child lived with each parent for the same amount of time during the tax year, and they do not file a joint return together,
- A non-parent, if no parent claims the child as a qualifying child although he or she may do so and only if the non-parent's AGI is higher than the highest AGI of any parent who may claim the child, or
- The person with the highest AGI, if none of the persons is the child's parent.
This information is found in Publication 501, Dependents, Standard Deduction, and Filing Information.
Also, FYI "He is being told" is an unhelpful statement in most cases. Generally, it is necessary to know who is telling someone something in order to assess it's credibility.
Advising someone to just "go and file" attempting to thwart the other parent is very bad advice in most cases.
I agree with the previous advice that it might be in the parties' best interests to file a joint return for 2023. However, that would mean that they would have to agree ahead of time as to exactly how any refund (if any) would be shared.
