The 2026 adoption tax credit: the new maximum, and who the phase-out reaches

A 2025 law made part of the adoption tax credit refundable for the first time ever, worth up to $5,120 in 2026 even with no tax owed. Here is the full $17,670 maximum, the income phase-out, and how the refundable and nonrefundable pieces actually work together.
The 2026 adoption tax credit covers qualified adoption expenses up to $17,670 per child, and for the first time, up to $5,120 of that is refundable even if a family owes little or no federal tax. The credit itself has existed for decades and simply rises with inflation most years. What changed is newer: a 2025 law made a slice of it refundable starting with the 2025 tax year, a meaningful shift for lower-income adoptive families who previously could not use the full credit because they did not owe enough tax to absorb it.
The 2026 maximum
For adoptions finalized with expenses paid in 2026, the credit covers qualified adoption expenses up to $17,670 per child — a modest inflation increase from $17,280 in 2025. Adopting a child with special needs, as certified by a state, qualifies for the full $17,670 automatically regardless of actual documented expenses, since Congress intended the credit to support those adoptions even when the paperwork trail is thin. Both figures come directly from the IRS's own 2026 inflation-adjustment guidance, Revenue Procedure 2025-32.
| Tax year | Maximum credit per child |
|---|---|
| 2025 | $17,280 |
| 2026 | $17,670 |
The credit is not a new idea reacting to the 2025 law — it dates to 1997, and has been a permanent fixture of the tax code since the American Taxpayer Relief Act of 2013, which locked in an earlier expansion rather than letting it lapse. What the 2025 law changed was not whether the credit exists, but whether a family with little tax liability can actually benefit from it.
What counts as a qualified expense
The IRS defines qualified adoption expenses as reasonable and necessary costs directly tied to a legal adoption: adoption fees, attorney fees, court costs, and travel expenses including meals and lodging while away from home for the adoption, according to the IRS's adoption credit page. One notable exclusion: expenses to adopt a spouse's child — a stepparent adoption — never qualify, no matter how much is spent. An unsuccessful domestic adoption attempt still counts, provided the child involved was a US citizen or resident; the credit does not require the adoption to have actually gone through.
The part that changed: a refundable slice
Historically the entire adoption credit was nonrefundable — it could only reduce tax actually owed, and any amount left over simply carried forward, unused, for up to five years before it expired for good. The One Big Beautiful Bill Act changed that starting with the 2025 tax year: whichever is smaller, the total credit or $5,120 in 2026, is now treated as fully refundable, paid out even to a family with no tax liability at all. Anything above that $5,120 slice remains nonrefundable and still follows the old rule — it offsets tax owed first, and unused amounts carry forward for up to five years before being forfeited.
The income phase-out
The credit is reduced, and eventually eliminated, as modified adjusted gross income (MAGI) rises through a fixed band — the same band applies regardless of filing status, unlike many other credits that treat joint filers differently:
| 2026 MAGI | Credit for $17,670 in expenses |
|---|---|
| $265,080 or less | $17,670 (full credit) |
| $285,080 (midpoint of the phase-out) | $8,835 (50% reduced) |
| $305,080 or more | $0 (fully phased out) |
The reduction is proportional across that $40,000 band: at the midpoint, exactly half the credit survives, which is why $285,080 in the table above cuts the $17,670 maximum precisely in half.
A worked example
A family with $22,000 in documented qualified adoption expenses and MAGI of $240,000 — comfortably below the phase-out threshold, so no reduction applies:
| Step | Amount |
|---|---|
| Qualified expenses (capped at $17,670) | $17,670 |
| Federal tax owed before the credit | $9,000 |
| Nonrefundable portion used to zero out tax owed | −$9,000 |
| Refundable portion (up to $5,120, paid regardless of tax owed) | $5,120 |
| Total tax savings and refund this year | $14,120 |
| Unused nonrefundable credit carried forward (up to 5 years) | $3,550 |
Of the $17,670 total credit, $12,550 was nonrefundable and $5,120 was refundable. The nonrefundable share first erased the entire $9,000 tax bill, leaving $3,550 of nonrefundable credit unused — that portion does not disappear, it carries forward against future tax bills for up to five years. The $5,120 refundable share is paid out the same year no matter what the tax bill was, which is the part of this credit that did not exist before 2025.
If an employer also helps pay
A separate benefit runs alongside the credit: an employer can reimburse up to $17,670 of adoption expenses in 2026 through a qualified adoption assistance program without that money counting as taxable wages, under the same $265,080–$305,080 MAGI phase-out as the credit itself. The two benefits cannot overlap on the same dollar of expense — whatever an employer reimburses tax-free, a family cannot also claim through Form 8839. A family with $25,000 in total adoption costs, $10,000 of it reimbursed by an employer program, can only claim the credit against the remaining $15,000, still capped at $17,670 overall between the two benefits combined. Sorting out which expenses went through which benefit, and keeping the paperwork to show it, is worth doing before filing rather than after.
How to claim it
The credit is claimed on IRS Form 8839, Qualified Adoption Expenses, attached to the federal return for the year the expenses were paid, with different timing rules depending on whether the adoption is domestic or foreign and whether it has finalized yet. Expenses paid in a year before the adoption finalizes are generally claimed for the year after they were paid; expenses paid in the year of finalization or later are claimed for the year paid.
Foreign adoptions have their own added wrinkle: expenses generally cannot be claimed at all until the adoption is final, unlike a domestic adoption where expenses paid in earlier years can be claimed the following year even before finalization. Two families spending the same amount, one adopting domestically and one from abroad, can end up claiming the identical total credit on very different timelines simply because of where the adoption is taking place.
