As the April 15 tax filing deadline approaches, many Americans could see tax refunds as high as $6,700 due to recent changes in federal tax credits under the One Big Beautiful Bill Act (OBBBA). The potential refund increase stems from two key credits: the Adoption Tax Credit, which is now refundable up to $5,000, and the Child Tax Credit (CTC), which offers up to $2,200 per child, including a refundable portion of $1,700. To qualify for the Adoption Tax Credit, taxpayers must adopt an eligible child and incur qualified expenses such as adoption fees and legal costs. The full credit is available for those with a modified adjusted gross income of $259,190 or less, phasing out completely at $299,189. The Child Tax Credit has also been expanded, requiring taxpayers to have earned at least $2,500 to claim the refundable portion. While these credits can provide significant financial relief, taxpayers need to ensure they claim both credits accurately to benefit before the filing deadline.
