Adoption Tax Credit Calculator (Form 8839)

For 2025 (IRS Rev. Proc. 2024-40), the maximum adoption credit is $17,280 per eligible child. For 2026 (IRS Rev. Proc. 2025-32), it rises to $17,670 per child. For a special-needs adoption, you get the FULL maximum regardless of actual qualified adoption expenses. For any other adoption, the credit equals your qualified adoption expenses up to that per-child cap.

Partially, starting with 2025. The One Big Beautiful Bill Act (OBBBA §70402, P.L. 119-21) made up to $5,000 per child (2025) refundable — you get that amount even if you owe no federal tax. For 2026, the refundable amount is indexed to $5,120 per child. The remainder of the credit stays nonrefundable: it offsets your current-year tax liability first, and any leftover carries forward for up to 5 years. Before 2025, the entire credit was nonrefundable.

Yes. The credit phases out ratably over a $40,000 band of modified adjusted gross income (MAGI). For 2025, the phase-out begins at $259,190 MAGI and the credit is fully eliminated at $299,190. For 2026, the band shifts to $265,080–$305,080. The reduction is proportional: for every dollar your MAGI exceeds the threshold, divided by the $40,000 band, that fraction of your credit is lost.

A state (or, per OBBBA §70403, certain Indian tribal governments) must determine the child cannot or should not be returned to their birth parents' home, and that the child has a specific factor or condition (such as ethnic background, age, membership in a sibling group, or a medical or emotional condition) that makes it reasonable to conclude the child cannot be placed without adoption assistance. Only domestic special-needs adoptions qualify — foreign adoptions never qualify as special-needs for this purpose, even if a foreign authority makes a similar finding.

Generally no. Under Form 8839 instructions (IRC §23(f)), if you're married you normally must file a joint return to claim the credit. The exception is being "considered unmarried": you lived apart from your spouse for the last 6 months of the year, the child lived in your home more than half the year, and you paid more than half the cost of keeping up the home. Taxpayers who meet that exception can claim the credit on a separate return.

Reasonable and necessary adoption fees, court costs, attorney fees, traveling expenses (including meals and lodging while away from home), and other expenses directly related to and for the principal purpose of the legal adoption of an eligible child. They do NOT include expenses for adopting your spouse's child (stepchild), surrogate parenting arrangements, expenses that violate state or federal law, expenses paid using funds from a government program, or expenses reimbursed by an employer's adoption assistance program (those instead qualify for the separate IRC §137 income exclusion).

Any nonrefundable adoption credit you can't use against your current-year tax liability carries forward for up to 5 years (IRC §23(c)), used in order until exhausted or the carryforward period expires. The refundable portion (up to $5,000 per child in 2025) is paid out immediately and is NOT part of the carryforward — you get it in full the year the credit is claimed regardless of liability.

Yes, but not for the same expenses. IRC §137 lets you exclude up to $17,280 (2025) of employer-provided adoption assistance from taxable income. If your employer reimburses some expenses tax-free under §137 and you pay other expenses out of pocket, you can claim the Form 8839 credit for the expenses NOT covered by the employer exclusion, subject to the same per-child cap and MAGI phase-out.
