Key Takeaways
- The 2026 adoption credit is worth up to $17,670 per child, with up to $5,120 refundable.
- The credit phases out between $265,080 and $305,080 of modified adjusted gross income for 2026.
- The IRS is automatically refunding some 2025 carryforwards; most people who filed on time need do nothing.
- A state special needs determination lets you claim the full credit regardless of actual expenses.
The adoption tax credit is worth up to $17,670 per child for 2026 — and a real chunk of it, up to $5,120, comes back to you even if your tax bill is already at zero. Refundability started with 2025 returns, and it changes who actually benefits from this credit.
Here’s how it works, who qualifies, and the income limits that determine how much you actually get.
What Changed Under the OBBB
Before the One Big Beautiful Bill, the adoption credit was nonrefundable only. If your tax liability was smaller than your credit, the unused portion just carried forward to future years — useful eventually, but no help the year you actually paid adoption expenses.
Starting with 2025 returns, up to $5,000 of the credit became refundable, rising to $5,120 for 2026 and now indexed for inflation going forward. For a lower-income family who owes little federal tax, that’s the difference between a credit that mostly sits on paper and thousands of real dollars landing in a refund.
The maximum total credit also grew: $17,670 per child for 2026, up from $17,280 in 2025. Both numbers move with inflation each year under Revenue Procedure guidance from the IRS, the same way other family tax credits get annual adjustments under the OBBB.
Who Qualifies
You can claim the credit for qualified adoption expenses paid to adopt an eligible child — generally anyone under 18, or a person of any age who’s physically or mentally unable to care for themselves.
Qualified expenses include adoption fees, court costs, attorney fees, and travel costs (including meals and lodging) directly tied to the adoption. Expenses reimbursed by an employer adoption-assistance program, or expenses tied to adopting a spouse’s child, don’t count.
The special needs exception is the one people miss most. If your state has determined the child has special needs — meaning the state has decided the child can’t or shouldn’t be returned to their birth parents, and that the child has a specific factor making adoption difficult without assistance — you can claim the full $17,670 credit for 2026 regardless of what you actually spent. Even a family with minimal out-of-pocket costs gets the entire credit in this situation.
The Income Phase-Out: Will You Get the Full Amount?
The credit doesn’t disappear at a cliff — it phases out gradually as your modified adjusted gross income (MAGI) rises through a $40,000 band.
For 2026:
- Full credit if your MAGI is $265,080 or below
- Partial credit, phased out ratably, between $265,080 and $305,080
- No credit once MAGI reaches $305,080 or more
That’s a wide window — the credit is designed to reach solidly middle- and upper-middle-income families, not just the lowest earners, which is part of why the new refundability piece matters so much for the families at the lower end of that range.

Real Examples
Jennifer and Marcus, a married couple with a combined MAGI of $95,000, adopt a child domestically in 2026 and pay $22,000 in qualified expenses. Their MAGI is well under the $265,080 threshold, so they claim the full $17,670 credit. If their federal tax liability for the year is only $9,000, they use $9,000 of the credit to zero out their bill — and up to $5,120 of the remainder comes back to them as a refund, not just a carryforward.
Priya, a single parent, adopts a child with a state-designated special needs classification and has just $3,000 in actual documented expenses. Because of the special needs exception, she still claims the full $17,670 credit, not the $3,000 she actually spent.
The IRS Is Sending Automatic Refunds on 2025 Carryforwards
The IRS has started issuing refunds to more than 50,000 taxpayers with adoption credit carryforwards, and it expects to finish most of them by the end of the year. It’s a one-time adjustment: for tax year 2025 only, unused credits from 2020 through 2024 can count toward the refundable portion, up to $5,000 per child.
If you filed your 2025 return before April 15, 2026, you generally don’t need to do anything, and the IRS says not to file an amended return just to request this. If you filed on extension or your account has another issue, your review may come later.
The $5,000 is a limit, not a promised payment. Depending on your return, you could get a smaller refund, a lower balance due or nothing, and a refund can be taken for certain past-due debts.
What to watch for:
- A notice: the IRS mails one explaining any change. Keep it with your 2025 records.
- Where to check: Where’s My Refund won’t show this. Use your IRS Online Account or a tax account transcript.
- When to amend: if your return left out the carryforward and the IRS can’t adjust it, or you disagree with the result, you may need Form 1040-X with Form 8839.
- Your 2026 return: old carryforwards don’t count toward the refundable portion for 2026, and your remaining carryforward may be smaller.
That last one is the mistake I’d watch for. Say Tom and Rosa had a $6,000 carryforward going into 2025, and their notice shows the refundable credit went up by $2,000. In this simplified example, they have $4,000 left to carry into 2026, not $6,000.
Use the increase in the refundable credit shown on your notice or transcript, not your total refund, and update the carryforward worksheet in the Form 8839 instructions.
How to Claim It
File Form 8839, Qualified Adoption Expenses, with your Form 1040. You’ll need the child’s identifying information (or an Adoption Taxpayer Identification Number if a Social Security Number isn’t yet available), documentation of your qualified expenses, and — for special needs claims — the state’s determination letter.
Keep every receipt and the adoption agency or court paperwork. The IRS can ask you to substantiate specific expense categories, and adoption-related documentation isn’t always easy to reconstruct months later if you didn’t save it as you went. If you’re using tax software or a preparer, see my rundown of free and low-cost filing options — most major platforms handle Form 8839 without an upgrade fee.

How It Stacks With Other Family Tax Credits
The adoption credit isn’t a substitute for the credits you’d otherwise claim for a child already part of your family — it’s specific to the adoption expenses themselves. Once your adopted child qualifies as your dependent, you separately claim the Child Tax Credit for kids under 17, and if you’re paying for daycare so you can work, the Child and Dependent Care Credit as well.
Down the road, if your adopted child heads to college, the American Opportunity and Lifetime Learning credits I cover in my full guide to education tax credits pick up where the CTC leaves off. None of these overlap with the adoption credit itself — they’re separate benefits for separate years of raising a kid.
Looking Ahead: 2027 and Beyond
The 2027 numbers are official. The IRS’s 2027 inflation adjustments set the maximum credit at $18,250 per child for 2027, with up to $5,280 of it refundable.
The phase-out moved up too: for 2027 it starts at $273,680 of modified adjusted gross income and ends at $313,680. If you’re adopting in 2027, those are the numbers to plan around; for an adoption that finalizes in 2026, the $17,670 and $5,120 figures above still apply. The 2028 amounts will come out in fall 2027.
Common Issues to Watch Out For
I hear a handful of the same questions and mistakes around this credit every filing season.
Assuming failed adoption attempts don’t count. They often do. Expenses from an unsuccessful domestic adoption attempt can still qualify, even if that specific adoption never finalized — a detail a lot of families don’t realize until it’s too late to claim it.
Missing the special needs exception entirely. Families who adopt through the foster care system in particular sometimes assume they can only claim what they spent, not realizing a state special-needs determination unlocks the full credit regardless of actual costs.
Confusing this with the Child Tax Credit. They’re separate credits for separate things — the adoption credit covers the cost of adopting, the CTC is an ongoing annual credit for having a qualifying child dependent.
Not tracking the five-year carryforward. If the nonrefundable portion of your credit exceeds your tax liability even after the refundable piece, don’t assume it’s lost — it carries forward for up to five years, so keep your Form 8839 details on hand for future returns.
Forgetting employer adoption assistance interacts with this credit. If your employer reimburses adoption expenses through a qualified assistance program, that reimbursed amount isn’t also eligible for the credit — you can’t double-dip on the same dollars.
