Deductions & credits

Thank you for your reply! I am the custodial parent, we are never married and live in separate households, only 1 very young child, and our court order allows for alternating tax years. At this point the other non-custodial parent has been the only one who has claimed our child and there had never been any issues until this tax year. I have a Tax Preparer so I’m assuming they automatically filed the Form 8332. But I filed my taxes before the other parent this year as Head of Household but did not claim our child as a dependent. I was told it wouldn’t affect the other parents taxes so I’m not sure if it actually did affect it or if there is another reason why they received an error.
