Expenses may be deductible even if the taxpayer pays them before an eligible child is identified. For example, some future adoptive parents pay for a home study at the beginning of the adoption process. These parents can claim the fees as qualified adoption expenses.
Qualified adoption expenses do not include expenses that a taxpayer pays to adopt their spouse’s child. They may, however, include adoption expenses paid by a registered domestic partner if that partner lives in a state that allows a same-sex second parent or co-parent to adopt their partner's child.
