Adoption Tax Credit Calculator

The calculator starts with the per-child adoption credit cap for the selected tax year: $17,670 for 2026 or $17,280 for 2025. It subtracts employer adoption benefits, other excluded reimbursements, and prior credit claimed for the same child before applying the MAGI phaseout.

After phaseout, the calculator separates the refundable and nonrefundable pieces. For 2026, up to $5,120 per eligible child may be refundable. The remaining current-year credit and any prior carryforward are treated as nonrefundable and can reduce federal income tax to zero.

A finalized U.S. special-needs adoption is modeled differently from an expense-based adoption because IRS guidance allows the full credit when the qualifying special-needs determination exists, even if qualified expenses are lower.

The adoption credit is now partially refundable

Before 2025, many families could use the adoption credit only to reduce tax and then carry unused nonrefundable credit forward. Beginning in tax year 2025, part of the current-year adoption credit can be refundable. For 2026, IRS inflation guidance lists a refundable portion of up to $5,120 per eligible child.

Carryforwards still need careful handling. IRS guidance says nonrefundable amounts carried forward cannot be used to calculate a refundable portion in future years. That is why the calculator separates current-year refundable credit from prior nonrefundable carryforward.

Key 2026 adoption credit rules

Qualified expenses and excluded expenses

Qualified adoption expenses include reasonable and necessary adoption fees, attorney fees, court costs, travel expenses including meals and lodging while away from home, and other costs directly related to the legal adoption. Home study fees may qualify even before a specific eligible child is identified.

Excluded costs matter just as much. Expenses for adopting a spouse's child, surrogate parenting arrangements, reimbursed expenses, costs paid by a federal, state, or local program, and amounts used for another federal credit or deduction should not be included in the credit base.

Domestic, foreign, and special-needs timing

Domestic adoption expenses can have different timing from foreign adoption expenses. A domestic adoption may allow expenses before finalization under the Form 8839 timing rules, and certain unsuccessful domestic adoption expenses may still qualify. Foreign adoption expenses are generally claimed when the adoption is final.

For a finalized adoption of an eligible U.S. child with a state or Indian tribal government special-needs determination, the taxpayer may be able to claim the full adoption credit even without qualified expenses. Keep the determination documents with the return records.

Connect the result to refund and credit planning
