Federal Adoption Tax Credit: Eligibility, Amount, and Filing

The federal adoption tax credit offsets up to $17,280 in qualified adoption expenses per child for 2026, and starting with tax year 2025 up to $5,000 of it is refundable, meaning you can receive that portion as a refund even if you owe no federal income tax.¹ You claim it on Form 8839, attached to your Form 1040. The rules cover most adoptions of children under 18, with a much more generous treatment for special needs adoptions and stricter timing rules for international ones.

Who Counts as an Eligible Child

An eligible child is anyone under 18, or a person of any age who is physically or mentally unable to care for themselves.² Most minor adoptions qualify without any extra analysis.

Two situations don’t qualify at all. Adopting your spouse’s child (a stepparent adoption) is excluded, and any expenses tied to a surrogate parenting arrangement are excluded regardless of how the arrangement is structured.³

Special Needs Adoptions Get the Full Credit

A child has “special needs” for this credit when a state or tribal government determines that the child can’t or shouldn’t return to the birth parents’ home and is unlikely to be adopted without assistance.⁴ Age, ethnic background, sibling group size, and medical conditions often factor into that finding.

When the adoption of a special needs child becomes final, you claim the full credit amount whether or not your actual expenses reached that figure. Even zero out-of-pocket costs still get you the maximum.² The written state determination is what unlocks this treatment, so keep a copy.

How Much You Can Get

The 2026 maximum is $17,280 per eligible child.¹ That cap is cumulative across all years for a single adoption, not annual. Adopt two children and each adoption gets its own $17,280 cap.

Income Phaseout

The credit shrinks as your modified adjusted gross income (MAGI) rises above an inflation-adjusted threshold and disappears entirely $40,000 above that. For 2025, the phaseout began at a MAGI of $259,190 and ended at $299,190.³ The 2026 numbers follow the same structure and will be slightly higher; the current year’s Form 8839 instructions have the exact figures.

Refundable Portion and Five-Year Carryforward

Up to $5,000 per qualifying child is refundable starting in tax year 2025.¹ Anything above your tax liability plus that refundable piece carries forward for up to five years.³

One catch: the $5,000 refundable portion applies only in the year you first claim the credit, not to carryforward amounts.¹ Carryforward balances can only offset actual tax owed in later years. If you can’t use the full credit within the five-year window, the rest is lost, so families with big credits and modest tax bills should map out how the credit will absorb across those years.

Which Expenses Qualify

Qualified adoption expenses are reasonable and necessary costs directly tied to the legal adoption of an eligible child, including:³

Adoption agency placement fees and home study costs
Attorney fees for the petition, court filings, and related legal work
Court filing fees and related charges
Travel expenses, including airfare, mileage, meals, and lodging while away from home for the adoption
Other direct costs like document translation or required medical exams

Expenses paid or reimbursed by a federal, state, or local government program don’t qualify.³ If you received a government adoption subsidy, only what you paid out of pocket counts. Surrogacy costs and stepparent adoption costs are out, as noted above.

When to Claim Each Expense

Timing is where families make the most costly mistakes on this credit. The rules split by whether the adoption is domestic or international.

Domestic Adoptions

For a U.S. child, expenses you pay before the year the adoption becomes final are claimed on the return for the year after you paid them. Pay $5,000 in agency fees in 2025 for an adoption that finalizes in 2027, and that $5,000 goes on your 2026 return. Once the adoption is final, expenses paid in the finalization year or any later year are claimed in the year you pay them.⁴

International Adoptions

Foreign adoptions follow a stricter rule: no expenses are claimable until the year the adoption becomes final. Spend $20,000 over three years on an international adoption that finalizes in 2026, and all of it goes on your 2026 return, subject to the $17,280 cap. If the foreign adoption never becomes final, you generally cannot claim any of those costs.⁴ That’s a financial risk worth pricing into the decision.

Failed Domestic Adoptions

A failed domestic adoption still qualifies for the credit. Timing follows the same pre-finalization rule: claim the expenses on the return for the year after you paid them.⁴ If you later attempt to adopt the same child again, combine expenses from every attempt on a single line of Form 8839.

Filing the Credit

You claim the credit by filing Form 8839, Qualified Adoption Expenses, with your Form 1040.⁵ The form asks for each child’s name, year of birth, and taxpayer identification number.

If You Don’t Have a Social Security Number Yet

When the adoption isn’t final and you can’t get a Social Security number for the child, apply for an Adoption Taxpayer Identification Number (ATIN) using Form W-7A.⁶ The IRS won’t process the credit without an identifying number for the child.

Filing Status

If you’re married, you generally must file jointly to claim the credit. Married filing separately usually disqualifies you. There is an exception for taxpayers who are legally separated or have lived apart from a spouse for at least the last six months of the tax year and meet other conditions, allowing head of household filing with the credit intact.⁴ Single filers and heads of household have no special filing-status obstacles.

Employer Adoption Assistance

If your employer runs a written qualified adoption assistance program, reimbursements from it can be excluded from your income up to a separately capped, inflation-adjusted amount.³ You can’t use both the credit and the exclusion for the same dollar of expenses. If your employer reimburses $8,000, that $8,000 is excluded from your income and subtracted from the expenses eligible for the credit.⁴ Families whose total costs exceed the cap can use both provisions, just not on overlapping dollars.

Records to Keep

You don’t send supporting documents with the return in most cases,⁷ but keep them in case the IRS follows up: the final adoption decree, any state or tribal special-needs determination, receipts for fees and travel, and signed placement agreements. The written special-needs determination matters especially, because it’s what entitles you to the full credit without matching expenses.
