IRS Adoption Credit Carryforward Refund — Automatic 2025 Adjustment Explained
The IRS is automatically refunding adoption credit carryforwards from 2020–2024 on 2025 returns, up to $5,000 per child, for 2025 only. Who qualifies, no amended return needed, what the IRS notice shows, offsets, timing through Dec 31, 2026, and how to fix your carryforward for 2026.

If you adopted a child in recent years and still had unused adoption credit sitting on your return, the IRS may be sending you money, without you doing anything. For tax year 2025 only, carryforwards from 2020–2024 can now count toward the refundable part of the adoption credit, up to $5,000 per qualifying child. The IRS is fixing affected accounts on its own, sending a notice, and issuing refunds. It says most should be done by December 31, 2026.

The short version
| Question | Short answer |
|---|---|
| What changed? | For 2025 only, 2020–2024 carryforwards can increase the refundable adoption credit |
| How much? | Up to $5,000 per qualifying child of refundable credit, not a guaranteed payment |
| Do I file anything? | No. The IRS adjusts accounts systemically. No amended return just for this |
| When? | Started late September 2026. Most done by Dec 31, 2026 |
| How will I know? | A notice, generally within 30 days of the adjustment |
| Where’s My Refund? | Won’t show it. Use the notice, IRS Online Account, or a transcript |
| Can it be offset? | Yes, against other tax or certain non-tax debts |
The IRS says it has already begun issuing refunds to more than 50,000 taxpayers. It also asks people not to call unless a notice or letter tells them to. Phone assistors don’t have more information than IRS.gov.
Why this is happening
Starting with tax year 2025, part of the adoption credit became refundable, meaning it can be paid to you even if you owe little or no tax. But the refundable amount on 2025 returns was figured without counting prior-year carryforwards. Those carried-forward amounts are the nonrefundable part of the credit, which can only reduce tax owed.
The Treasury Department then clarified how it reads the Working Families Tax Cuts law. For tax year 2025 only, carryforwards still available in 2025 can be included when figuring the refundable portion, subject to the $5,000 per qualifying child limit and the other adoption credit rules.
The IRS isn’t updating the 2025 forms. Instead it identified returns where the refundable credit “may not have been fully allowed” and is correcting them systemically.
Who may get the adjustment
Per the IRS Q&A, you may get the systemic adjustment if all of these apply:
- You filed a 2025 Form 1040, 1040-SR, or 1040-NR.
- You claimed, or were eligible to claim, the adoption credit on Form 8839, Qualified Adoption Expenses.
- You had prior-year adoption credit carryforwards available for use in 2025.
- Your 2025 return and account information show your refundable adoption credit should be increased.
You may not get one if you already received the correct refundable credit, had no carryforwards available in 2025, didn’t file a 2025 federal return, or never claimed the credit even though you were eligible.
Which carryforwards count
| Rule | What the IRS says |
|---|---|
| Carryforward window | Unused adoption credit carries forward up to 5 years |
| Years usable in 2025 | Carryforwards that started in 2020 through 2024 |
| Before 2020 | Expired. Can no longer be claimed |
| Several years of carryforward | The oldest is used first |
Edge cases
- Didn’t claim the credit on your 2025 return? If you filed Form 8839 for any year from 2020 through 2024 that showed a carryforward, you may still get the adjustment. If the IRS doesn’t have enough information, you may need to file Form 1040-X with Form 8839.
- Claimed the credit but left the carryforward off? The IRS may not be able to adjust systemically. You may need an amended return to correct the carryforward.
- Something else open on your account? The IRS may wait until that issue is resolved, then decide on the adjustment. You generally don’t need to amend just for this.
Timing: who’s automatic and who waits
| Your situation | What to expect |
|---|---|
| Filed 2025 return before April 15, 2026 | Generally automatic. No action needed |
| Filed under an extension | Reviewed later in 2026, after the return is processed |
| Account has ID theft indicators, freezes, dependency conflicts or other issues | Reviewed later in 2026, after the issue is resolved |
If you filed by the October 15, 2026 extension deadline, you’re in the “later in 2026” group. Nothing extra to file. The IRS reviews the account once your return is processed.
The IRS notice and your refund
The IRS sends a notice, generally within 30 days of the adjustment. It shows the amount and whether it was refunded or applied to another tax or non-tax debt. The news release and Q&A don’t name a specific notice number, so look for a notice about your 2025 account that explains an adoption credit change.
- Agree? No reply needed. Keep the notice with your 2025 records.
- Disagree? You may need to file Form 1040-X with Form 8839 and supporting information.
- Offset to a debt? You’ll get a notice about the offset. If part of a joint refund belongs to a spouse who doesn’t owe the debt, see Form 8379, Injured Spouse Allocation.
- Still a balance due? The adjustment may only reduce what you owe. The notice shows the new amount. Pay what you can by its due date, or ask about a payment plan.
- Interest: included if required by law. Your notice or transcript shows it.
- Lost the notice? The IRS may not reissue it, but you can view a copy in your IRS Online Account.
The adjustment doesn’t change your adjusted gross income, taxable income, or qualified adoption expenses. It’s a credit against tax.
Illustrative examples
These are made-up scenarios to show how the rules fit together. They are not IRS figures and not a way to predict your exact refund. The IRS computes the actual amount from your return and account.
| Illustrative situation | How the IRS rules apply |
|---|---|
| One adopted child; $9,000 of unused credit carried forward from a 2022 adoption; little 2025 tax owed | Refundable portion for 2025 can’t exceed $5,000 for that child, even though the carryforward is larger. Any refund also depends on other credits, payments, and offsets |
| Same family, but they owe a past-due federal debt | Part or all of the overpayment may be applied to the debt. The notice says so |
| Carryforwards from 2021 and 2023 | The 2021 amount is used first (oldest first) |
| Only carryforward started in 2019 | Expired. Nothing to apply in 2025 |
| Filed 2025 return in September 2026 under an extension | Reviewed later in 2026 once the return is processed |
Illustrative: fixing your carryforward for 2026
Say your notice or transcript shows the refundable adoption credit increased by $4,000, but the refund you received was $3,400 because $600 went to an offset. (Illustrative numbers.)
To refigure what carries into 2026, the IRS says to complete the Nonrefundable Adoption Credit Carryforward Worksheet—Line 18 in the 2025 Form 8839 instructions. On line 8, enter:
- your 2025 Form 8839, line 18, plus
- the increase in your refundable adoption credit, $4,000 in this sketch.
Use the credit increase, not the $3,400 refund. The IRS warns that the refund, reduced balance, or amount due on the notice can include other payments, credits, offsets, interest, or penalties. A larger 2025 refundable credit may mean less carryforward for future years.
When you might still need to amend
The adjustment covers the adoption credit and related account math only. Per the IRS, you may still need Form 1040-X if:
- You need to correct another item: filing status, income, dependents, qualified adoption expenses, employer-provided adoption benefits, your carryforward amount, or another credit.
- You used your adoption credit carryforward as a nonrefundable credit and could have used other credits instead. The IRS lists the D.C. first-time homebuyer credit (Form 8859), Residential Clean Energy Credit (Form 5695, Part I), qualified electric vehicle credit (Form 8834), alternative fuel vehicle refueling property credit (Form 8911), general business credit (Form 3800), prior-year minimum tax credit (Form 8801), and credit to holders of tax credit bonds (Form 8912).
- You disagree with the IRS adjustment.
Estimated tax penalty? The IRS won’t automatically recompute or remove it. If the larger refundable credit would reduce or eliminate the penalty, follow your penalty notice, or file Form 843 to ask for abatement or a refund.
Preparers and software: complete the 2025 return with the forms and instructions as issued. Don’t override Form 8839 or put amounts on lines where they don’t belong. The IRS handles the change systemically.

What to do now
- Watch your mail through the end of 2026. You don’t need to call the IRS.
- Check your IRS Online Account or a tax account transcript. Where’s My Refund won’t show this.
- Compare the notice with your 2025 return, then keep both, plus Form 8839, your carryforward worksheets, expense records, and any W-2 box 12 code T benefit information.
- Refigure your 2026 carryforward with the line 18 worksheet, using the credit increase, not the refund amount.
- Amend only if something else is wrong or you disagree, not just to request this refund.
- Planning 2026? Run a rough refund-vs-owed number in the federal tax calculator. It’s an educational estimate. It doesn’t model the adoption credit, so treat any refundable adoption credit as a separate add-on.
What this does not do
- It’s not personalized tax advice and can’t tell you whether your account will be adjusted.
- It doesn’t calculate your refund. The IRS figures that from your return and account.
- It doesn’t cover state adoption credits or employer plan details.
- Educational only. Confirm with IRS.gov/AdoptionCredit or a tax professional.
