The Adoption Credit, stacked.
$17,670 federal credit per child in 2026 (up to $5,120 of it now refundable). Stack with the §137 employer-provided adoption benefits exclusion and shield over $35,000 of adoption costs from federal tax.
The 60-second pitch
The federal Adoption Credit under IRC §23 is one of the most generous personal credits in the code — and one of the least-used because most families adopt once or twice in a lifetime. For 2026, the credit is $17,670 per child of qualified adoption expenses.
Under OBBBA, the credit is now partially refundable for the first time — up to $5,120 (2026) can come back as a refund even if it exceeds your tax liability. Any remaining nonrefundable portion still carries forward 5 years under §23(c). So even moderate-income adoptive families almost always extract the full credit.
The phaseout starts at $252,150 MAGI (2024) and fully eliminates the credit roughly $40,000 higher. Above the top of the range, no credit. Verify the current-year phaseout band when filing.
Stack it with the §137 employer-provided adoption assistance exclusion. If your employer offers an adoption assistance plan, up to the same dollar amount (~$17,670 in 2026) can be excluded from your W-2 wages. The credit and exclusion can both apply to the same adoption — but not to the same dollars. Split your qualified expenses: assign $17,670 to the §137 exclusion, then assign the next $17,670 of expenses to the §23 credit. That's ~$35,000 of adoption costs federally tax-free.
Special twist: special-needs adoptions (state-determined) get the full credit even if the actual expenses are lower than $17,670. So even an adoption costing $4K can yield the full $17,670 credit.
Real-world example
The setup. Daniel and Erika begin a private domestic adoption in 2024 and finalize in 2025. Total qualified adoption expenses (agency fees, attorney, court costs, home study, travel): $31,500. Erika's employer offers an §137 adoption assistance plan with up to $16,000 of reimbursement.
The §137 exclusion. Erika requests $16,000 of reimbursement from her employer in 2025. That $16,000 is excluded from her W-2 box 1 (federal wages) — though it remains subject to FICA in most plans. Federal income tax saved at 22% bracket: $3,520.
The §23 credit. Remaining qualified expenses paid out-of-pocket: $31,500 − $16,000 = $15,500. Under §23(b)(3)'s no-double-benefit rule, only this $15,500 counts toward the §23 credit basis. Both spouses are under the $252,150 phaseout. Credit = $15,500 against their federal tax liability.
The timing. Because the adoption finalized in 2025, the §23 credit is claimed on the 2025 return. (Domestic adoption: expenses paid before finalization are deductible in the year after they're paid; expenses paid in the year of finalization are deductible that year; foreign adoption: all expenses deductible in the year of finalization.) Erika's employer §137 dollars are excluded in the year they hit her W-2.
If they had a high tax liability. If their 2025 federal tax owed is $18K, the credit wipes out $15,500 of it — paying only $2,500 of tax. If their tax owed is $9K, $9K of credit applies and the remaining $6,500 carries forward 5 years under §23(c).
Total federal benefit. $3,520 (W-2 exclusion) + $15,500 (credit) = $19,020 of federal tax shielded from a $31,500 adoption.
The step-by-step checklist
- Confirm the adoption is an "eligible adoption." §23(d) covers adoption of any child under 18 (or any physically/mentally incapable individual). Adopting your spouse's child does NOT qualify.
- Track qualified expenses in a tax folder. Adoption fees, attorney fees, court costs, travel (lodging + meals while away from home), re-adoption expenses for foreign adoptions, home study fees, "reasonable and necessary" related expenses. NOT: surrogacy, expenses for a spouse's child, anything reimbursed by an employer (those go to §137).
- Get an ATIN if needed. If you don't yet have the child's SSN at filing time (common in private domestic and foreign adoptions), apply for an Adoption Taxpayer Identification Number (ATIN) on Form W-7A.
- Decide §137 vs. §23 expense allocation. No double-counting. Sort qualified expenses into "employer-reimbursed" (§137 exclusion, no FIT or state tax) and "out-of-pocket" (§23 credit). Aim to fill both buckets up to the cap.
- Check your employer's plan. A §137 plan must be a written plan, non-discriminatory, with notice to employees. If your employer doesn't have one, ask HR. Many large employers offer $5K-$25K of adoption assistance and don't advertise it.
- File Form 8839. "Qualified Adoption Expenses." This is the schedule that computes both the §23 credit and §137 exclusion. Include the child's name, year of birth, SSN/ATIN, identifying info, and whether special-needs.
- Special-needs adoptions: claim the FULL credit. If the state has determined the child has special needs (a state-specific status — typically children harder to place because of age, sibling group, medical/emotional condition), the full $17,670 (2026) credit applies regardless of actual expenses.
- Timing — domestic vs. foreign. Domestic: expenses paid before the year of finalization are claimed in the year after payment; expenses paid in the year of finalization are claimed that year. Foreign: all expenses are claimed in the year of finalization, never before.
- Phaseout math. 2024: phaseout $252,150–$292,150 MAGI. If your MAGI is $272,150, you've lost 50% of the credit. Plan: max your 401(k), HSA, FSA to drop MAGI back under $252,150 if possible.
- Track the 5-year carryforward. Unused credit carries forward up to 5 years. Tax software handles this on Form 8839 if you're consistent year-to-year.
- Failed adoption? §23(a)(2)(B) allows the credit for unsuccessful domestic adoption attempts. The "child" never has to exist as your child for you to claim the credit on the expenses incurred.

Audit risk flags
- Adopting a spouse's child. Step-parent adoptions explicitly disqualify under §23(d)(1)(C). Defense: Don't claim. Period.
- Surrogacy expenses. Surrogacy is NOT adoption under §23. The pre-2020 PLRs that hinted otherwise are non-precedential. Defense: Do not include surrogacy in qualified expenses.
- Double-counting §137 and §23. Same expense claimed under both — penalty. Defense: Track expenses by source on a per-receipt basis.
- Wrong-year claim. Domestic adoption expense timing is counterintuitive — pre-finalization expenses move into the next year. Defense: Confirm finalization date and run the year-of-claim test for each expense.
- Phaseout miscalc. Software occasionally uses AGI instead of MAGI; the §23 MAGI adds back certain items. Defense: Hand-tie phaseout on Form 8839 line 7.
- Special-needs claim without state determination. The "special needs" status must come from the state, in writing. Defense: Keep the state's special-needs determination letter in the file.
When NOT to do this (or where you can't)
- Step-parent adoption. No credit, ever.
- MAGI > $292,150 (2024). Fully phased out. Above the cliff, your only lever is §137 employer benefits.
- You owe almost no federal tax. Only up to $5,120 (2026) is refundable; the rest is nonrefundable. The 5-year carryforward helps, but if you'll consistently owe near zero, the nonrefundable portion may expire unused.
- You used surrogacy. Not eligible.
- You received a state adoption subsidy that exceeds expenses. The subsidy reduces qualified expenses dollar-for-dollar.
