Adoption Tax Credit Calculator
Estimate your 2026 federal Adoption Tax Credit under the One Big Beautiful Bill Act. Plug in your qualified expenses, MAGI, tax liability, and any prior-year carryforward, and you'll see your refundable and nonrefundable credit at the post-OBBBA per-child caps of $17,670 and $5,120.
Filing Status
The 2026 phase-out range ($265,080–$305,080 MAGI) is the same for every filing status. It does not double for joint filers.
Type of Adoption
If a state or Indian tribal government has determined a child has special needs, you can claim the full $17,670 even if you paid $0 in qualified expenses (IRC §23(a)(3); tribal recognition was added by OBBBA §70403).
Qualified Adoption Expenses
Adoption agency fees, attorney fees, court costs, and reasonable travel/lodging. Auto-capped at the $17,670 per-child statutory maximum. For special-needs adoptions, this field is treated as the full statutory amount regardless of what you spent.
Modified Adjusted Gross Income
Form 1040 line 11, plus any Puerto Rico income exclusion, Form 2555 lines 45 & 50 (foreign earned income/housing), and Form 4563 line 15. The 2026 phase-out runs from $265,080 to $305,080.
2026 Federal Tax Liability (Before Credits)
Your federal income tax before credits (Form 1040 line 18). This caps how much of the credit you can apply as nonrefundable through Schedule 3 line 6c.
Prior-Year Carryforward (2021–2025)
Unused nonrefundable adoption credit from up to five prior tax years. The carryforward stacks on top of this year's credit, but it only offsets tax liability. It does not generate a refund.

How the Adoption Tax Credit works in 2026
For tax year 2026, the federal Adoption Tax Credit reaches $17,670 per eligible child, and up to $5,120 of that is refundable for the first time under the One Big Beautiful Bill Act (P.L. 119-21 §70402). The maximum and phase-out thresholds are inflation-adjusted each year under IRC §23(h); 2026 figures come from IRS Rev. Proc. 2025-32 (IR-2025-103).
You claim the credit on Form 8839, which then flows to Schedule 3 line 6c (nonrefundable portion) and Form 1040 line 30 (refundable portion). Qualifying expenses include adoption agency and attorney fees, court costs, re-adoption costs, and reasonable travel and lodging. Surrogacy arrangements, stepparent adoptions, and any costs reimbursed by an employer or paid with federal/state grants do not count.
The phase-out range, $265,080 to $305,080 of modified AGI, is identical for every filing status. Married couples filing jointly do not get a doubled phase-out range, unlike many other credits. Married Filing Separately is generally barred under IRC §23(f)(1) unless the spouses lived apart for the last six months of the year.
OBBBA changes: refundable portion and tribal recognition
For tax years before 2025, the adoption credit was fully nonrefundable. It could zero out your tax bill, but it would not produce a refund. Unused amounts carried forward up to five years.
OBBBA §70402 changed that beginning in tax year 2025. For 2026, up to $5,120 per child of the current-year credit is refundable through Form 1040 line 30, meaning you can receive that amount even if you owe no federal income tax. The remaining nonrefundable portion still carries forward up to five years, but the refundable piece does not (IRC §23(c)(1) as amended by OBBBA §70402(c)).
OBBBA §70403 also expanded the special-needs determination to recognize Indian tribal governments alongside states, effective for adoption proceedings finalized after July 2025.
Special-needs adoptions: the full credit, regardless of expenses
If a state or Indian tribal government has determined that a child cannot or should not be returned to their birth parents and that placement requires adoption assistance (a "special-needs" determination under IRC §23(d)(3)), you can claim the full $17,670 in 2026 even if you paid $0 in qualified expenses. That matters for foster-to-adopt and tribal-court adoptions, where the placing agency typically absorbs most of the costs.
Example: an MFJ couple finalizes a special-needs adoption in 2026 with $0 out-of-pocket expenses and a $275,080 MAGI. The tentative credit is the full $17,670; the 25% MAGI phase-out reduces it by $4,418, leaving $13,253. Of that, $5,120 is refundable. The remaining $8,133 offsets tax liability up to its limit, with anything above that carrying forward.
Refundable vs. nonrefundable: how the math splits
The calculation order matters. After applying the per-child cap and the MAGI phase-out, the calculator pulls the refundable portion first (capped at $5,120 per child) directly out of the current-year credit. Whatever is left becomes nonrefundable, gets stacked with any prior-year carryforward, and then gets capped by your federal tax liability for the year. Anything still unused after the liability cap rolls forward to 2027.
The refundable cap is per child, so a family adopting two children in 2026 could receive up to $10,240 refundable plus a nonrefundable component. That is a meaningful change from the pre-OBBBA regime, where lower-income adoptive families often saw the credit go partially or fully unused.
2026 MAGI phase-out schedule
The table below shows how the credit shrinks as your modified AGI passes $265,080. The reduction percentage and dollar reduction are identical for every filing status, assuming a single child at the full $17,670 tentative credit.

Frequently Asked Questions
Common questions about the Adoption Tax Credit in 2026
What is the maximum federal adoption tax credit for 2026?
$17,670 per eligible child for tax year 2026, with up to $5,120 of that refundable through Form 1040 line 30. The maximum is inflation-adjusted each year under IRC §23(h) as amended by OBBBA §70402(b); 2026 figures come from IRS Rev. Proc. 2025-32.
At what income does the adoption tax credit phase out in 2026?
The credit begins to phase out at $265,080 of modified AGI and is fully eliminated at $305,080. The same range applies to every filing status. Unlike many other credits, the phase-out does not double for joint filers.
Can I get the adoption tax credit if I owe no taxes?
Yes. The One Big Beautiful Bill Act made up to $5,120 per child refundable starting in 2025 (IRC §23(a)(4)). Anything beyond that cap is nonrefundable but carries forward for up to five years against future tax liability.
What expenses qualify for the adoption tax credit?
Adoption agency fees, attorney fees, court costs, re-adoption costs, and reasonable and necessary travel and lodging while away from home (IRC §23(d)(1)). Surrogacy arrangements, stepparent adoptions, and any expenses reimbursed by an employer or paid with federal or state program grants do not count.
How does the credit work for a special-needs adoption?
If a state or Indian tribal government has determined the child has special needs under IRC §23(d)(3), you can claim the full $17,670 for 2026 even if you paid $0 in qualified expenses. The tribal-government recognition was added by OBBBA §70403, effective for adoptions finalized after July 2025.
Can I claim the credit if my employer paid some adoption costs?
Yes, but you cannot double-dip. Employer-provided adoption assistance excluded from your wages under IRC §137 reduces the qualified expenses eligible for the credit. The W-2 Box 12 Code T amount is subtracted from your total expenses before the per-child cap is applied.
What if my credit is bigger than my tax bill?
Up to $5,120 per child is refundable in 2026 even with no tax liability. Any additional nonrefundable portion that exceeds your tax liability carries forward for up to five tax years. The refundable portion itself does not carry forward; only the nonrefundable amount does (IRC §23(c)(1) as amended by OBBBA).
When can I claim the credit if the adoption is not yet finalized?
For domestic adoptions, qualified expenses are claimed in the year after they are paid (or in the year of finalization, whichever is earlier). For foreign adoptions, expenses can only be claimed in the year the adoption becomes final (IRC §23(a)(2)).
