Qualified expenses
Adoption fees, court costs, attorney fees, travel expenses for the adoption, and meals and lodging while away from home. Expenses to adopt a spouse's child don't qualify, and neither do surrogacy costs; the credit is for adoption in the legal sense.
Special needs adoptions
For state-determined special needs adoptions, you claim the full $16,810 regardless of actual expenses. The adoption doesn't need to be finalized with expenses for this. The determination comes from the state child welfare agency, usually documented in the adoption assistance agreement, and it's the document the IRS wants to see.
When to claim, the timing trap
Domestic adoptions claim expenses the year after they're paid, until the year the adoption becomes final, when that year's expenses are claimed currently. International adoptions claim nothing until the adoption is final, then claim everything. A failed domestic adoption's expenses still qualify on the same delayed schedule, an unexpected kindness in the rules. Getting the year wrong is the most common error on Form 8839.
What changed in 2025
Legislation enacted in 2025 made a portion of the credit, up to $5,000, refundable beginning with 2025 returns. Before that the credit was entirely nonrefundable with a five-year carryforward, which left lower-income adoptive families waiting years to collect. The refundable slice now pays out regardless of tax liability, with the nonrefundable remainder still carrying forward.
Employer assistance and the income phase-out
Employer adoption assistance can be excluded from income up to a separate, similar cap, but the same dollars can't back both the exclusion and the credit. Both benefits phase out at higher incomes over a range that adjusts annually. Families near the phase-out should look at which year expenses land in, since the timing rules above create some room to steer.
Common questions
- Is the credit refundable?
- Partially, as of 2025: up to $5,000 is refundable, and the remainder is nonrefundable with a five-year carryforward. For 2024 and earlier returns the credit was entirely nonrefundable.
- Do failed adoption expenses count?
- For domestic adoptions, yes: qualified expenses of an unsuccessful attempt are claimable on the delayed timing schedule. International adoption expenses only count if the adoption becomes final.
- Does adopting my stepchild qualify?
- No. Expenses to adopt a spouse's child are specifically excluded from the credit.
- What documentation should I keep?
- The adoption decree, agency and attorney invoices, travel receipts, and for special-needs claims the state's adoption assistance agreement. The IRS reviews these claims more often than their size suggests.
