Families who finalized an adoption in 2026 can claim a federal credit worth up to $17,670 per child, an increase from the $17,280 ceiling that applied to expenses tied to a 2025 adoption. The larger shift is not the dollar figure but the mechanics behind it: up to $5,120 of that credit is now refundable, meaning a family can collect part of it even if they owe little or nothing in federal income tax. For most of the credit’s history, families with modest tax bills lost value they had legally earned because the credit only offset taxes actually owed. A 2025 tax law rewrote that rule, and the refundable amount grew again heading into 2026.
The 2026 Maximum Climbs to $17,670 Per Child
The Internal Revenue Service updates the adoption credit every fall as part of its annual inflation-adjustment package, which resets dozens of tax provisions ahead of the coming filing season. For qualified adoption expenses tied to an adoption finalized in 2026, the maximum credit rises to $17,670 per eligible child, a $390 increase over the amount that applied to a 2025 adoption. The credit covers reasonable, necessary costs directly connected to the legal adoption of a child under 18 or a person incapable of self-care, including adoption fees, court costs, attorney fees and adoption-related travel expenses such as meals and lodging away from home.
The updated ceiling comes from Revenue Procedure 2025-32, the guidance the IRS released in October 2025 alongside more than 60 other inflation-adjusted figures for tax year 2026, including new standard deduction amounts and marginal tax brackets shaped by the same law that changed the adoption credit. Families claim the credit on Form 8839 attached to the return that covers the year the adoption became final, which means a family that finalized an adoption in 2026 will file for it on the return due in the spring of 2027, not on the return they file this year.

Refundability Arrives for the First Time in the Credit’s History
For nearly three decades after Congress created the adoption credit in 1996, it was strictly nonrefundable. A family that owed less in federal income tax than the credit was worth could carry the unused balance forward for up to five years, but could never collect the difference as a cash refund. Families with modest incomes in the year they finalized an adoption often lost real value simply because their tax liability was too small to absorb a credit worth five figures.
The law that changed this, signed in July 2025, made the adoption credit partially refundable starting with tax returns for adoptions finalized that year, and indexed the refundable portion to inflation going forward. For 2026, up to $5,120 of the credit can be refunded even if a filer owes no federal income tax at all, up from the $5,000 refundable ceiling that applied to 2025 adoptions. The remaining, larger portion of the credit above that refundable amount still works the old way: it offsets tax liability dollar for dollar and can be carried forward for up to five years if it isn’t fully used in the year the adoption became final.
The distinction matters most for lower- and middle-income adoptive families, who are statistically more likely to owe too little federal tax to absorb a five-figure nonrefundable credit in a single filing year. Before 2025, those families routinely carried forward credit balances they might never fully use, since the carryforward window is capped at five years and any unused amount is often unrecoverable once that period lapses. The new refundable floor guarantees a portion of the benefit reaches a family’s pocket regardless of income, even in a year with little tax liability.
Income Limits and Rules for Special-Needs Adoptions
The credit is not unconditional. It phases out for higher earners, and for the 2026 tax year the reduction begins once a filer’s modified adjusted gross income reaches $265,080, with the credit eliminated entirely once income hits $305,080. Those thresholds apply the same way regardless of filing status, so a married couple filing jointly faces the identical phase-out band as a single filer.
Special-needs adoptions get separate treatment. A child qualifies as having special needs, for purposes of this credit, when a state child-welfare agency determines the child cannot or should not return to their birth family and would be difficult to place for adoption without financial assistance; the designation is unrelated to whether the child has a disability. Families adopting a child the state has designated as special needs can claim the full credit even when their actual documented adoption expenses fall short of that amount, a rule that recognizes many special-needs placements come through the foster care system with minimal direct costs to the adoptive family.
One recent change affects who makes that special-needs determination. Indian tribal governments now have the authority to determine whether a child has special needs for purposes of the credit, a status previously reserved for state agencies. The rule does not extend to foreign adoptions: a child adopted internationally who might otherwise meet a special-needs definition abroad does not qualify for the federal special-needs exception, regardless of the circumstances of the placement.
The nonrefundable carryforward rules add one more wrinkle families should track closely. Any portion of the credit that goes unused in the year an adoption is finalized can still be carried forward and applied against tax liability in later years, but the IRS has been explicit that a carried-forward nonrefundable balance cannot later be converted into a refund. The refundable portion is calculated only in the year tied to the adoption itself, which means families with fluctuating income may want to time major deductions or retirement contributions with an eye toward maximizing what they can claim as a refund in that specific filing year, rather than assuming a lean tax year now can be made whole with a refund later.
