Adoptive families filing federal tax returns in 2026 have a big reason to pay closer attention to Form 8839: for the first time in the credit’s history, a portion of the Adoption Tax Credit is refundable. That means eligible families can get money back even if they owe little or no federal income tax. Below are the key facts on how much the credit is worth, who qualifies, the income phase-out, and how to actually claim it.

1. What Is the Adoption Tax Credit

The Adoption Tax Credit is a federal tax credit designed to offset the cost of adopting a child. It covers a range of “qualified adoption expenses,” including:

• Adoption fees charged by agencies
• Court costs and attorney fees
• Traveling expenses (including meals and lodging while away from home)
• Other expenses directly related to, and for the principal purpose of, the legal adoption of an eligible child

The credit applies broadly across adoption types — domestic adoptions, international adoptions, and adoptions of children with special needs — though the rules differ slightly depending on the category, especially for special-needs adoptions (more on that below).

2. What Changed Under the OBBBA

The One Big Beautiful Bill Act (OBBBA) made a structural change to the Adoption Tax Credit that adoptive families have wanted for years: part of the credit is now refundable. Previously, the Adoption Tax Credit was entirely nonrefundable, meaning it could only reduce a filer’s tax liability to zero — any unused amount could be carried forward for up to five years, but families with little tax liability often couldn’t use the full credit at all.

Under the OBBBA:

• Up to $5,000 of the credit is now refundable, according to the IRS, for qualifying tax years.
• The change applies to tax years beginning after 2024 — in practical terms, this means it first applies to 2025 tax returns, which most families file during the 2026 filing season.
• Any remaining nonrefundable portion of the credit above the refundable amount still carries forward for up to five years, as under prior law.

This is a meaningful shift: lower-income adoptive families who previously couldn’t benefit from the full credit because they didn’t owe enough tax can now receive at least part of it as a refund.

3. 2026 Credit Amount and Income Phase-Out

The maximum qualified adoption expense amount and the refundable portion are both adjusted for inflation each year, so the exact dollar figures move slightly from year to year. Here’s what’s confirmed versus what’s being reported for the 2026 filing season:

• 2025 tax year (confirmed on the IRS site): a maximum credit of $17,280 per child, with up to $5,000 of that refundable.
• 2026 tax year figures: some tax preparers and publications, including CPA Practice Advisor, report inflation-adjusted amounts of roughly $17,670 in maximum qualified expenses and about $5,120 as the refundable cap. These figures had not been independently confirmed on the IRS’s own adoption credit page as of this writing, so treat them as preliminary estimates rather than official numbers until the IRS updates its published guidance.

The credit also phases out for higher-income families based on modified adjusted gross income (MAGI). The IRS publishes the exact phase-out range each year on its adoption credit page — if your household income is in the upper range, your available credit is reduced on a sliding scale, and above the top of the range it’s eliminated entirely. Because these thresholds are also adjusted annually for inflation, it’s worth checking the current IRS figures before you file rather than relying on last year’s numbers.

4. Special Needs Adoptions

Adoptions of children determined to have special needs get more favorable treatment under the credit. If a state (or, under a parity provision added by the OBBBA, a tribal government) determines that a child has special needs, adoptive parents may be able to claim the full maximum credit amount for that year — even if their actual documented qualified adoption expenses were lower than the maximum, or even zero.

Key points on special-needs eligibility:

• The child must be a U.S. citizen or resident at the time the adoption process began.
• A state or tribal government must have determined the child cannot or should not be returned to their parents’ home, and that the child likely won’t be adopted without assistance.
• The OBBBA extended the same recognition to Indian tribal government determinations of special needs that previously applied primarily to state determinations, closing a gap that had left some Native families without equal access to this provision.

5. How to Claim the Credit

To claim the Adoption Tax Credit, you’ll need to complete and attach Form 8839, Qualified Adoption Expenses, to your federal Form 1040. On the form, you’ll report:

• Information identifying the eligible child (or children)
• Whether the child has special needs or is a child with a disability
• Your total qualified adoption expenses for the year
• Any employer-provided adoption assistance you received (which is calculated on the same form, since it reduces the amount of expenses eligible for the credit)

Good recordkeeping matters here. Because the credit is based on qualified adoption expenses, keep receipts, invoices, and statements from adoption agencies, attorneys, and courts, along with documentation of any state or tribal special-needs determination. If you’re later asked to substantiate the credit, these records are what you’ll need.

6. FAQ

Can I claim the credit for a failed adoption attempt?
Expenses related to an unsuccessful attempt to adopt a U.S. child can generally still qualify, and in some cases can be combined with expenses from a later, successful adoption. The rules differ for failed attempts to adopt a foreign child, where expenses generally aren’t creditable unless the adoption is finalized. Because this area has nuance, it’s worth reviewing the specific rules on the IRS adoption credit page or checking with a tax professional for your situation.

Does the refundable portion affect other benefits?
Refundable credits generally increase your refund amount rather than being counted as new “income,” but every household’s tax situation is different, especially if you receive other income-tested benefits. If you’re unsure how a larger refund might interact with other programs you rely on, it’s worth checking with a tax professional.

Can employer adoption assistance be combined with the credit?
Yes, but not on the same dollar of expenses. If your employer provides adoption assistance under a qualified program, that assistance may be excludable from your income up to a separate annual limit, but you can’t claim the Adoption Tax Credit for the same expenses that were already covered by excludable employer assistance. Form 8839 walks through this coordination step by step.

Bottom Line

The 2026 filing season brings a genuinely useful change for adoptive families: part of the Adoption Tax Credit — up to $5,000 under confirmed 2025 IRS figures, with slightly higher preliminary estimates reported for 2026 — is refundable for the first time. Combine that with the special-needs provisions and the newly extended tribal government parity, and more adoptive families than ever may be able to put this credit to use. As always, confirm the current-year dollar amounts and phase-out thresholds directly on the IRS adoption credit page before you file, since inflation adjustments happen every year.
