Adoption Tax Credit Guide

What the Adoption Tax Credit Is and How It Works

The adoption tax credit under Internal Revenue Code Section 23 helps families recover part of the cost of adopting a child. It is a dollar-for-dollar credit equal to the qualified adoption expenses you pay, up to a per-child maximum, and it covers nearly all forms of adoption: domestic agency and independent adoptions, foster care adoptions, and intercountry adoptions. The one adoption it does not cover is the adoption of your spouse's child.

The headline number for 2026 is $17,670 per eligible child, and $17,280 for 2025. That ceiling is the most a single adoption can generate, and it is a cumulative cap that runs across all the years you pay expenses for one child, not a per-year amount. The credit was historically nonrefundable, which limited its value for lower-income families, but that changed for 2025: a portion is now refundable, which we cover in detail below.

Two Parts: The Credit and the Exclusion

There are actually two adoption tax benefits that work together. The credit under §23 offsets your tax for expenses you pay yourself. The exclusion under §137 lets you leave employer-provided adoption assistance out of your taxable income. They share the same per-child dollar limit and the same income phase-out, and you can use both for one adoption, but never for the same dollars of expense. Most families use only the credit; families whose employer offers an adoption-assistance program use both.

2026 and 2025 Amounts and the MAGI Phase-Out

The maximum credit, the refundable portion, and the phase-out thresholds are adjusted for inflation each year. The table below shows both years side by side.

The phase-out works differently from most credits. Under §23(b)(2)(A), it is based on modified adjusted gross income, and the thresholds are the same for every filing status. There is no separate, doubled range for married couples; a single filer and a married couple filing jointly both begin to lose the credit at the same $265,080 of MAGI for 2026. The phase-out is ratable over a fixed $40,000 band: the reduction equals the credit multiplied by the amount your MAGI exceeds the lower threshold divided by $40,000. At or above the upper threshold the credit is zero.

MAGI for the adoption credit is your Form 1040 AGI increased by the foreign earned income exclusion and the Puerto Rico and possessions exclusions, which for most filers means ordinary AGI. Because the phase-out runs over a fixed band, a taxpayer near the threshold can sometimes recover part of the credit by lowering MAGI, for example with a larger pre-tax retirement contribution. You can estimate the effect with the AGI and MAGI Calculator and see exactly how MAGI is built in the MAGI Guide.

How the Credit Is Calculated (Form 8839)

The credit is figured on IRS Form 8839, Qualified Adoption Expenses, and the calculation runs in a fixed order.

Step 1: Determine the Credit Base

For a regular adoption, the base is your qualified adoption expenses, reduced by any employer-excluded amounts, up to the per-child maximum. For a special-needs adoption, the base is the full per-child maximum regardless of what you spent.

Step 2: Apply the MAGI Phase-Out

If your MAGI is above the year's lower threshold, reduce the credit by the phase-out fraction. Form 8839 rounds that fraction to three decimal places. At or above the upper threshold, the credit is eliminated.

Step 3: Split Refundable and Nonrefundable

Beginning with 2025, up to $5,120 per child for 2026 ($5,000 for 2025) of the allowed credit is refundable and paid regardless of tax. The remainder is nonrefundable.

Step 4: Apply the Tax Limit and Carryforward

The nonrefundable portion can only offset your federal income tax for the year, computed on the Credit Limit Worksheet. Any unused nonrefundable amount carries forward up to five years under §23(c). The Adoption Tax Credit Calculator performs each of these steps for you.

The New Refundable Portion (One Big Beautiful Bill Act)

The most important change to the adoption credit in years arrived with the One Big Beautiful Bill Act (P.L. 119-21, §70402), effective for tax years beginning in 2025. For the first time, part of the adoption credit is refundable. Up to $5,000 per qualifying child for 2025, indexed to $5,120 for 2026, is now paid to you even if you owe no federal income tax at all.

This matters enormously for the families who need help most. Before 2025, an adoptive family that owed only $2,000 of income tax could use only $2,000 of a $17,000 credit in the first year, and the rest sat as a carryforward that took years to absorb, if it ever was. Now that same family receives the full refundable portion as a refund, and the nonrefundable balance still carries forward.

How the Split Works

• The allowed credit (after the per-child cap and MAGI phase-out) is divided into a refundable portion and a nonrefundable portion.
• The refundable portion is the smaller of the allowed credit or $5,120 per child for 2026 ($5,000 for 2025). It is paid in full as a refund.
• The nonrefundable portion is whatever is left. It is limited to your income tax and carries forward up to five years.
• A nonrefundable amount carried forward from a prior year cannot become refundable in a later year; only current-year credit qualifies for the refundable cap.

The refundable portion is per qualifying child, so a family adopting two children can receive up to twice the refundable cap. The change does not raise the overall maximum credit; it changes how much of it you can actually use right away.

What Counts as a Qualified Adoption Expense

Qualified adoption expenses under §23(d)(1) are the reasonable and necessary expenses directly related to, and whose principal purpose is, the legal adoption of an eligible child. The most common categories are:

• Adoption agency and placement fees.
• Court costs and attorney fees.
• Travel expenses while away from home, including meals and lodging.
• Re-adoption expenses for a foreign child and other costs directly tied to the legal adoption.

Just as important is what does not qualify. The following are never qualified adoption expenses:

• Expenses for adopting your spouse's child.
• Costs of a surrogate parenting arrangement.
• Expenses that violate state or federal law.
• Expenses paid or reimbursed by an employer or any government program.
• Expenses already used to claim another credit or deduction.

An eligible child under §23(d)(2) is a child under age 18, or a person of any age who is physically or mentally incapable of caring for themselves. The credit follows the child, so it applies whether the adoption is open or closed, agency or independent, domestic or foreign.

Special-Needs Adoptions

The single most valuable feature of the adoption credit is the special-needs rule. If a state, or beginning in 2025 an Indian tribal government, determines that a child has special needs, the adoptive parents may claim the full maximum credit for the year the adoption is final even if they paid little or no qualified adoption expenses. For 2026 that deemed amount is $17,670 per child.

The tax meaning of special needs is specific and often misunderstood. Under §23(d)(3), it is a child the state has determined cannot or should not be returned to the birth parents and who probably will not be adopted without assistance, usually documented in an adoption-assistance agreement. It is a child-welfare classification, not a statement about the child's medical condition or disability. A child with a serious medical condition adopted through a private domestic agency is generally not special needs for this credit unless a state agency made that determination; conversely, a healthy child adopted from foster care with a signed determination is.

Because the deemed credit applies regardless of out-of-pocket cost, families who adopt from foster care frequently receive the full credit even though their direct expenses were minimal. The refundable portion applies to the special-needs credit too, so a low-income foster-adoptive family can receive the refundable amount as a refund and carry the balance forward.

Claim-Year Timing Rules

One of the most error-prone parts of the credit is deciding which tax year an expense belongs to, because the answer depends on whether the child is a U.S. child or a foreign child and whether the adoption is final.

Domestic (U.S.) Child

• Expenses paid in a year before the adoption becomes final are claimed in the tax year after the year you paid them.
• Expenses paid in the year the adoption becomes final are claimed that year.
• Expenses paid after the adoption is final are claimed in the year you pay them.
• This applies even if the adoption is never finalized, so expenses on a domestic adoption that falls through can still be claimed.

Foreign Child

• No expenses are claimed until the adoption becomes final.
• In the year the adoption is final, all qualified expenses from that and prior years are claimed together.
• Expenses paid after the year of finality are claimed in the year paid.

A special-needs credit is claimed in the year the adoption becomes final. Because the timing rules can push expenses into a year other than the one in which the checks were written, mapping each payment to its correct claim year is the first step we take on any multi-year adoption.

The Employer Adoption Assistance Exclusion (Section 137)

If your employer offers a written adoption-assistance program, amounts it pays toward your adoption can be excluded from your taxable income under IRC §137, up to the same per-child limit as the credit ($17,670 for 2026) and subject to the same MAGI phase-out. Employer assistance is usually reported in box 12 of your Form W-2 with code T.

You can use both the exclusion and the credit for one adoption, but the law prevents a double benefit on the same dollars. In practice, the expenses your employer reimbursed are excluded under §137, and only the expenses you paid yourself are available for the §23 credit. A family with $25,000 of expenses and $10,000 of employer assistance excludes the $10,000 and claims the credit on the remaining $15,000 (capped at the per-child maximum).

Two differences matter. First, the exclusion is never refundable, while the credit now is in part. Second, the exclusion reduces your income for the year it applies, which can itself affect other phase-outs. The exclusion is figured in Part III of Form 8839. For families near the income threshold, we model the credit and the exclusion together because they share the same phase-out.

Carryforward and Coordination With Other Credits

Under §23(c), the nonrefundable portion of the credit that your tax cannot absorb in the current year carries forward for up to five years, or until used, whichever comes first. The carryforward is used after the current year's credit, and a carried-forward amount always stays nonrefundable, so it can never later be claimed as a refund even after the 2025 refundable change.

The adoption credit coordinates cleanly with the other family tax benefits, because it is a separate, one-time credit tied to the adoption rather than an annual credit for the child. An adopted child who has a valid Social Security number and meets the usual tests is treated like any other child for:

• the child tax credit (annual, for a qualifying child under 17), covered in the Child Tax Credit (OBBBA) Guide;
• the child and dependent care credit and a dependent care FSA, compared in the Dependent Care FSA vs Tax Credit guide;
• the earned income tax credit, with limits in the EITC Income Limits Guide.

Families building long-term savings for an adopted child may also look at the OBBBA Trump Account. Claiming the adoption credit in the same year as these other credits is common and fully allowed.

Real-World Scenarios

When the Standard Adoption Credit Rules Do Not Apply

• Adopting a spouse's child. Expenses to adopt your spouse's child never qualify for the credit or the exclusion, no matter how the adoption is structured.
• Multi-year cumulative cap. The per-child maximum applies across all years for one adoption, reduced by amounts claimed for that child in earlier years. A second-year claim is limited to the remaining cap.
• Failed domestic adoption. Qualified expenses on a domestic adoption that is never finalized can still be claimed, but the timing rule still pushes pre-finality expenses to the following year. Foreign adoptions that fall through generally produce no credit.
• Married filing separately. A married taxpayer generally must file jointly. A narrow exception applies only if you lived apart from your spouse for the last six months of the year and meet the household and residency tests.
• Carryforward cannot become refundable. The 2025 refundable change applies only to current-year credit. A nonrefundable amount carried into 2025 or 2026 from an earlier year stays nonrefundable.
• Reimbursed or law-violating expenses. Expenses reimbursed by an employer or government program, or that violate state or federal law, are excluded from qualified expenses entirely.
• State adoption credits. Several states offer their own adoption credits or income subtractions with different limits and rules. Those are separate from the federal §23 credit and are not covered here.
