A nonrefundable tax credit for qualified adoption expenses paid to adopt an eligible child. The credit may be allowed for the adoption of a child with special needs, even if you do not have any qualified expenses. For 2017, the credit is reduced if your modified adjusted gross income (MAGI) falls between $203,541 and $243,539; the credit is eliminated if your MAGI is $243,540 or more. In addition, there is an income exclusion for employer-provided adoption assistance.
