Adoption Tax Credit: Eligibility and Limits

The federal adoption tax credit covers qualified expenses of adopting an eligible child — up to $17,670 per child for 2026 (Rev. Proc. 2025-32). Since 2025, part of it is refundable: up to $5,120 per child for 2026. For 2027 the IRS raised the limit to $18,250, with up to $5,280 refundable and a phaseout from $273,680 to $313,680 of modified AGI (Rev. Proc. 2026-35, section 3.04). You qualify if you adopted or tried to adopt a child under 18 (or a person of any age who can't care for themselves), your modified AGI is below $305,080, and you file jointly if married.

This guide covers eligibility, what expenses count, which year to claim them, and how employer benefits interact with the credit. To run the phaseout, refundable, and carryforward math for your numbers, use the adoption tax credit calculator.

Who qualifies for the adoption tax credit?

According to the Form 8839 instructions, three conditions must all be true:

1. Filing status: single, head of household, qualifying surviving spouse, or married filing jointly. Married people filing separately qualify only if they lived apart from their spouse for the last six months of the year, the child lived with them more than half the year, and they paid over half the cost of keeping up the home.
2. Income: modified AGI below $305,080 for 2026 ($299,190 for 2025), or you are only using a carryforward from an earlier year.
3. Child information: you report the required information about the child in Part I of Form 8839.

The phaseout range is the same for every filing status — married couples do not get a higher threshold.

Who counts as an eligible child?

• Any child under age 18. A child who turns 18 during the year is eligible for the part of the year before the birthday.
• Any person of any age who is physically or mentally unable to care for themselves.

What makes a child "special needs"?

A special-needs determination unlocks the full credit even with no out-of-pocket expenses. All three must be true:

1. The child was a U.S. citizen or resident (including U.S. territories) when the adoption effort began.
2. A state (or, since 2025, an Indian tribal government) determined the child can't or shouldn't return to the parents' home.
3. The state or tribe determined the child won't be adopted unless assistance is provided to the adoptive parents.

The instructions stress that a child having a medical condition, being part of a sibling group, or being older is not enough by itself — the government must actually make the determination. An adoption assistance agreement with a state child-welfare agency is typical evidence. Children adopted from other countries can never be special-needs children for this purpose, even if they are re-adopted in a U.S. court.

What adoption expenses qualify?

Qualified adoption expenses are reasonable and necessary costs directly related to, and for the principal purpose of, the legal adoption of an eligible child.

Home studies, required medical exams for the child, and immigration fees in a foreign adoption generally count when they are required for the adoption. Keep receipts; the IRS's Notice 2010-66 lists documents it accepts, such as the adoption order, home study, and agency contract.

If you made more than one attempt to adopt one child — for example, a failed placement followed by a successful one — the expenses are combined under a single $17,670 limit. Twins or siblings each get their own limit.

When do you claim the adoption credit?

Timing is set by law, not by choice, and it depends on whether the child was a U.S. citizen or resident when the effort began.

Domestic adoption (U.S. child)

For a U.S. child, you can claim expenses even if the adoption never becomes final.

Example: a couple pays $6,000 in 2024, $9,000 in 2025, and the adoption becomes final in 2026 when they pay another $4,000. The 2024 expenses were claimable on the 2025 return; the $9,000 and $4,000 are both claimable on the 2026 return. The combined total is still capped at the per-child limit, minus anything claimed earlier.

Foreign adoption

A foreign adoption that never becomes final produces no credit. When a foreign adoption is final depends on whether the country is a party to the Hague Adoption Convention; Rev. Proc. 2005-31 (non-Hague) and Rev. Proc. 2010-31 (Hague) set the rules, which the Form 8839 instructions summarize. In many non-Hague adoptions you can choose the year of the foreign decree or the year of a U.S. re-adoption that happens within the next two years.

Special needs adoption

For a special-needs child, you claim the full credit in the year the adoption becomes final. If you previously claimed expenses for the same child, the full amount is reduced by what you already claimed.

How the refundable part works since 2025

Before 2025, the adoption credit was entirely nonrefundable: it could only reduce tax you owed, so families with modest tax bills often waited years to use it. The One Big Beautiful Bill Act changed that. For each eligible child:

• The first $5,000 (2025) or $5,120 (2026) of the credit is refundable and goes on Form 1040's refundable credit line.
• Everything above that is nonrefundable and offsets tax only.
• Unused nonrefundable credit carries forward for up to five years and stays nonrefundable — you can't convert a carryforward into a refund in a later year.
• Exception for tax year 2025 only: carryforwards from 2020 through 2024 that were available in 2025 can count toward the 2025 refundable amount, up to $5,000 per child. The IRS is applying this by adjusting accounts automatically (see the next section); for 2026 and later the normal rule applies again.

The refundable amount is figured per child. A family adopting two children in 2026 with enough expenses can receive up to $10,240 refundable. For 2026 the IRS's adoption credit page adds a filing step: if you claim the refundable part, you must also complete Schedule 3-A (Form 1040), Federal Public Benefit. See the OBBBA tax changes guide for the rest of the law.

IRS automatic refunds for 2025 adoption credit carryforwards (October 2026)

On October 16, 2026 the IRS announced in IR-2026-123 that it had begun issuing refunds to more than 50,000 taxpayers with adoption credit carryforwards. The Treasury Department changed its reading of the law: for tax year 2025 only, unused adoption credit carried forward from 2020 through 2024 can increase the refundable part of the 2025 credit, still capped at $5,000 per child. The 2025 Form 8839 and its instructions don't include this, so some 2025 returns did not get the full refundable credit.

What the release and the IRS carryforward Q&A say you should do:

You do not need to file an amended return just to get this adjustment. The IRS sends a notice, generally within 30 days of the change, showing the amount and whether it was refunded or applied to another tax or non-tax debt. The adjustment does not change your AGI or taxable income, and it can be less than $5,000: it depends on your carryforward, the number of children, the income phaseout and your account balance. Carryforwards from before 2020 had already expired. Keep the notice with your 2025 return, because it shrinks the carryforward you have left for 2026. To refigure it, complete the Nonrefundable Adoption Credit Carryforward Worksheet in the 2025 Form 8839 instructions and, on its line 8, enter your 2025 Form 8839 line 18 amount plus the increase in refundable credit shown on the notice or your account transcript. Use only that increase, not the total refund on the notice, which can include other offsets and interest. The carryforward you take into 2026 is nonrefundable again.

How do income limits reduce the credit?

The credit phases out ratably over a $40,000 MAGI band — $265,080 to $305,080 for 2026. MAGI for this purpose is AGI plus any foreign earned income exclusion, foreign housing exclusion or deduction, and excluded income from Puerto Rico or American Samoa. If you live abroad and use the exclusion, add it back before checking the limit; the foreign earned income exclusion guide explains those amounts.

A family at $275,080 of MAGI loses one quarter of the credit; a family at $295,080 loses three quarters. The calculator does this math, and our MAGI guide lists ways to bring MAGI down, such as pre-tax retirement and HSA contributions.

Employer adoption assistance and the credit

Employers can pay or reimburse adoption expenses under a separate written qualified adoption assistance program. For 2026 you can exclude up to $17,670 per child from income, with the same MAGI phaseout as the credit. The exclusion is figured on Form 8839, Part III, and you must complete Part III before Part II.

Rules to know:

• No double benefit. An expense your employer pays is not a qualified expense for the credit. But you can use both the exclusion and the credit for different expenses of the same adoption.
• Payroll taxes still apply. The benefit is exempt from income tax withholding but subject to Social Security, Medicare, and FUTA (Pub. 15-B).
• Foreign adoption timing. Employer payments made before a foreign adoption is final must be included in income in the year paid; you take the exclusion in the year the adoption becomes final. Adjust your W-4 or estimated payments to cover the tax in between.
• Special-needs exclusion. If your employer has a qualified program and you adopt a special-needs U.S. child, you may exclude the full amount even if the employer paid less.
• S corporation owners with more than 2% of the stock can't use the exclusion.

Example: combining the exclusion and the credit

You pay $36,000 to adopt a child from abroad, finalized in 2026, and your employer reimburses $17,670. You exclude $17,670 from income. The remaining $18,330 of expenses is still eligible for the credit, capped at $17,670. Only $660 of your costs goes unused.

How to claim the credit on Form 8839

1. Part I: list each child — name, birth year, whether the child has special needs, whether foreign, and the SSN or ATIN. For a child placed with you who doesn't yet have an SSN, apply for an adoption taxpayer identification number on Form W-7A.
2. Part III (if your employer paid anything): figure the excludable benefits.
3. Part II: enter the per-child limit, prior-year amounts for the same child, current-year qualified expenses, MAGI, and the phaseout.
4. Split the credit: the refundable part goes on Form 1040; the nonrefundable part goes on Schedule 3 and is limited by the credit limit worksheet.
5. Keep the carryforward worksheet for any unused nonrefundable credit.

Common adoption credit mistakes

• Claiming domestic expenses in the year paid when the adoption wasn't final yet — they belong on the next year's return.
• Claiming a foreign adoption before it is final.
• Assuming a medical diagnosis equals special needs. Without a state or tribal determination, you claim actual expenses only.
• Filing separately without meeting the lived-apart test.
• Forgetting earlier claims for the same child, which reduce the remaining limit.

After the adoption: other credits

Once the child is part of your household, you may also qualify for the $2,200 child tax credit (if the child has a valid SSN by the return's due date), the child and dependent care credit, and head of household status if you're unmarried. Check the child tax credit calculator, and see the 2026 inflation adjustments guide for the other family-credit limits.
