Adoption Tax Credit 2026: Limits, the Refundable Portion and Form 8839

The adoption tax credit 2026 limit is $17,670 per eligible child, and up to $5,120 of that amount is refundable, so a family can receive it even with no income tax to offset. The credit phases out between $265,080 and $305,080 of modified adjusted gross income (MAGI), and you claim it on Form 8839.

These figures come from Rev. Proc. 2025-32, the IRS notice of 2026 inflation adjustments, and the refundable piece exists because of the One Big Beautiful Bill Act (OBBBA) signed in July 2025. Below is how the adoption tax credit 2026 rules work, what counts as a qualified expense, how special needs adoptions are treated, and a worked example showing how the refundable and nonrefundable parts split.

Adoption Tax Credit 2026 Figures at a Glance

The IRS sets the dollar limits each year. For taxable years beginning in 2026, Rev. Proc. 2025-32 states that "the maximum credit allowed for other adoptions is the amount of qualified adoption expenses up to $17,670" and that the credit "begins to phase out under § 23(b)(2)(A) for taxpayers with modified adjusted gross income in excess of $265,080 and is completely phased out for taxpayers with modified adjusted gross income of $305,080 or more."

The 2025 column comes from the Instructions for Form 8839 (2025), which apply to 2025 returns, including late or amended ones. The 2026 column applies to returns filed in early 2027.

Two points about these limits catch people out. The cap applies per child, so adopting siblings gives each child a separate limit. The cap is also cumulative for each child across years: if you claimed part of the credit for a child in an earlier year, Form 8839 subtracts those earlier expenses from the limit before you claim more.

What the OBBBA Changed: the Refundable Portion

From 2012 through 2024, the adoption credit was fully nonrefundable. It could reduce your income tax to zero, and any excess carried forward, which left many lower and middle income adoptive families with a credit they could only use slowly or never use at all.

The OBBBA changed that. The IRS summary of the law on its Working Families Tax Cuts page says that "Beginning tax years after Dec. 31, 2024, up to $5,000 (indexed for inflation) of the adoption credit may be refundable." For 2026, the inflation-adjusted figure is $5,120, per Rev. Proc. 2025-32.

The refundable amount is worked out child by child. On the 2025 Form 8839, each child's refundable credit is the smaller of that child's credit (after any income phase-out) or $5,000, and the per-child amounts are added together. The rest of each child's credit is nonrefundable.

The same law also gave Indian tribal governments the same standing as states when deciding whether a child has special needs, which matters for the special needs rule covered below.

Carryforwards and the one-time 2025 adjustment

Under the general rule, a carryforward stays nonrefundable. The Form 8839 instructions say "Any credit carryforward can only be a nonrefundable credit. Unused nonrefundable credit can't be turned into a refundable credit in a future year."

The IRS has since made a single-year exception. Its questions and answers on adoption credit carryforwards explain that prior-year carryforwards available for use in 2025 can count toward the refundable portion, capped at $5,000 per eligible child, and that "This treatment applies for tax year 2025 only." The IRS is making this adjustment to accounts automatically. Families who filed their 2025 return before April 15, 2026 "do not need to take any action," and the IRS asks taxpayers not to file an amended return solely to request it. If you had a carryforward from an earlier Form 8839 but left it off your 2025 return, an amended return may be needed to correct that information. For 2026 and later years, the general rule applies again.

What Counts as a Qualified Adoption Expense

Form 8839 defines qualified adoption expenses as "reasonable and necessary expenses directly related to, and for the principal purpose of, the legal adoption of an eligible child." In practice, that covers adoption agency fees, attorney fees, court costs, and travel while away from home, including meals and lodging. Re-adoption expenses for a foreign child also qualify.

Several costs are excluded. You cannot count expenses paid with funds from a state, local or federal program, expenses that violate state or federal law, costs of a surrogate parenting arrangement, or costs of adopting your spouse's child. Anything reimbursed by your employer or otherwise is out, and so is any amount already allowed as a credit or deduction elsewhere on your return.

An eligible child is any child under 18, or a person of any age who is physically or mentally unable to care for themselves. If the child turned 18 during the year, the child counts for the part of the year before that birthday.

Who Can Claim the Credit

Your filing status must be single, head of household, qualifying surviving spouse or married filing jointly. Married couples generally have to file a joint return, with a narrow exception for spouses who are legally separated or living apart and meet other requirements.

Income is the second test. If your MAGI falls between $265,080 and $305,080 for 2026, your credit is reduced in proportion to how far into that $40,000 band you are. For this credit, MAGI is your adjusted gross income plus certain excluded income, including any amount excluded under the foreign earned income exclusion on Form 2555. Families just above the threshold sometimes lower AGI in the year they claim the credit through pre-tax retirement deferrals or deductible HSA contributions reported on Form 8889.

Special Needs Adoptions

A special needs adoption gets the full credit regardless of what you spent. The IRS adoption credit page says that "State and Indian tribal governments determine whether a child has special needs" and that families adopting such a child can claim "The full credit even if you didn't pay any qualified adoption expenses."

Three conditions apply under the Form 8839 instructions. The child must be a citizen or resident of the United States or its territories when the adoption effort began. A state (including the District of Columbia) or an Indian tribal government must have determined that the child cannot or should not be returned to the parents' home. That government must also have determined that the child will not be adopted unless assistance is provided to the adoptive parents.

A child who has a disability or medical condition is not automatically a child with special needs for this credit. The written determination from the state or tribal government is what counts, so keep that letter with your tax records. For a special needs adoption that becomes final in 2026, you enter $17,670 as qualified expenses on Form 8839, minus any expenses you already used for that child in a prior year.

When You Can Claim It: Domestic and Foreign Adoptions

The year you claim the credit depends on where the child is from and when the adoption becomes final.

• Domestic adoption still in progress: expenses paid before the year the adoption becomes final are claimed in the year after you pay them.
• Domestic adoption finalized: expenses paid in the year of finalization, or later, are claimed in the year paid.
• Unsuccessful domestic adoption: if the child is a U.S. citizen or resident, you can still claim expenses for an attempt that fails, using the same timing as an adoption that is not yet final.
• Foreign adoption: you claim the credit only in the year the adoption becomes final, and at that point you can include eligible expenses from earlier years.

If the child does not have a Social Security number by the time you file, Form 8839 accepts an adoption taxpayer identification number (ATIN), which you request on Form W-7A. That is a different form from the one used for an individual taxpayer identification number on Form W-7, which is for people who are not eligible for an SSN.

Worked Example: How the 2026 Credit Splits

The example below uses 2026 amounts and follows the calculation steps on the 2025 Form 8839 (the 2026 form had not been released when this was written). "Tax available" is the income tax left after the other credits that the form's credit limit worksheet takes first.

Family B's phase-out fraction is ($281,080 minus $265,080) divided by $40,000, which is 0.400. Multiplying $17,670 by 0.400 gives a $7,068 reduction, so the credit falls to $10,602. Family A and Family C have small tax bills, so the refundable $5,120 is a large share of what they receive in 2026, and the unused nonrefundable credit carries forward for up to five years. Under the general rule described earlier, those carryforwards stay nonrefundable. Family C paid nothing, but the special needs rule still gives the full $17,670 credit.

The adoption credit and the child tax credit can both apply in the year the child joins your household, and the credit limit worksheet sets the order in which nonrefundable credits use up your tax.

How to Claim the Adoption Tax Credit 2026 on Form 8839

You figure the credit on Form 8839, Qualified Adoption Expenses, and attach it to Form 1040. The form has three parts:

1. Part I lists each child, with the identifying number, birth year, special needs status, foreign child status and whether the adoption is final.
2. Part II figures the credit. On the 2025 form, the refundable amount goes to Form 1040, line 30, and the nonrefundable amount goes to Schedule 3 (Form 1040), line 6c.
3. Part III figures the exclusion for employer-provided adoption benefits, which appear in box 12 of Form W-2 with code T.

For 2026 returns, the IRS adoption credit page adds a new step: "You must complete Schedule 3-A (Form 1040), Federal Public Benefit, if you are claiming the refundable Adoption Credit." The IRS also says to complete and attach as many Forms 8839 as you need when you adopted more than three children.

If your nonrefundable credit exceeds your tax, keep the carryforward worksheet from the instructions. You will need it to claim the remaining credit in the following year, and any amount still unused after five years is lost.

Using the credit with employer adoption assistance

If your employer runs a written qualified adoption assistance program, you can exclude up to $17,670 of those benefits from income in 2026, subject to the same MAGI phase-out. The IRS says you "must claim any allowable exclusion before claiming any allowable credit," and the same dollar of expense cannot count for both. The exclusion is not available to an employee who owns more than 2% of an S corporation employer. For how this benefit fits with other employer perks, see our guide to fringe benefits and taxes.

Records to keep

Keep agency contracts and invoices, court and attorney bills, travel receipts, the special needs determination if you have one, W-2s showing code T benefits, and every Form 8839 you file for the child. A refund that depends on the credit is easier to support when the paperwork matches each line of the form. Families setting up savings for a newly adopted child may also want to read about Trump accounts for children, which became available after the same 2025 law.

Frequently Asked Questions

How much is the adoption tax credit for 2026? The maximum is $17,670 per eligible child, and up to $5,120 of that amount is refundable. The credit begins to phase out above $265,080 of MAGI and is gone at $305,080.

Is the adoption credit refundable in 2026? Partly. Up to $5,120 per child can be paid to you even if you owe no income tax. The rest of the credit is nonrefundable and can be carried forward for up to five years.

Can carryforwards from earlier years become refundable? For tax year 2025 only, the IRS is automatically letting carryforwards from earlier years count toward the refundable portion, up to $5,000 per eligible child. From 2026 onward, carryforwards are nonrefundable again.

Do I need receipts for a special needs adoption? For the credit amount, no. A child with special needs, as determined by a state or Indian tribal government, qualifies you for the full $17,670 in the year the adoption becomes final even with no expenses. You still need the written special needs determination.

Can I claim the credit if a domestic adoption falls through? Yes, for a U.S. child. Expenses for an unsuccessful domestic adoption are treated like expenses for an adoption that is not yet final. Expenses for a foreign adoption that never becomes final do not qualify.
