The Section 137 adoption assistance exclusion lets you leave employer-paid adoption benefits off your taxable income. For 2026, you can exclude up to $17,670 per eligible child, provided your employer runs a qualifying written plan and your income falls below the phase-out range. The exclusion covers agency fees, legal costs, and travel tied to a legal adoption, and it works alongside, but not on top of, the separate adoption tax credit.
The 2026 Dollar Limit
The maximum you can exclude for the 2026 tax year is $17,670 per eligible child. That cap is a lifetime figure for each child, not an annual one. If your employer provides adoption assistance across several years for the same child, every payment counts toward the single $17,670 ceiling. Anything your employer pays above that amount becomes taxable wages.
The IRS adjusts the limit each year for inflation, so check the current Form 8839 instructions before you file. For comparison, the 2025 limit was $17,280.
Special Needs Adoptions
If you finalize the adoption of a child with special needs, you can claim the full exclusion amount even if your actual expenses were lower. The statute treats your qualified expenses as reaching the maximum. Spend only $4,000 on a special needs adoption that becomes final in 2026, and the law lets you exclude the full $17,670.
A child counts as having special needs when a state or tribal government determines the child cannot or should not return to the birth parents’ home and is unlikely to be adopted without assistance to the adoptive family. The child must also be a U.S. citizen or resident.
Income Phase-Out
The exclusion shrinks once your modified adjusted gross income crosses a threshold that moves with inflation each year. The 2025 phase-out began at a MAGI of $259,190 and wiped out the exclusion entirely at $299,190. The 2026 figures are slightly higher; the current Form 8839 instructions carry the exact numbers.
The structure is the same every year. The phase-out window is $40,000 wide. Take the amount your MAGI exceeds the lower threshold, divide by $40,000, and that fraction is the share of the exclusion you lose. Land halfway through the range and you keep half.
Which Children and Expenses Qualify
An eligible child is one who is either under age 18 or physically or mentally incapable of self-care. A few situations are carved out entirely. Adopting your spouse’s child does not qualify. Neither do surrogate parenting arrangements. The adoption also has to be a legal one through a recognized process, not an informal family handoff.
Qualified adoption expenses are the reasonable and necessary costs tied directly to a legal adoption:
- Agency fees for placement services
- Attorney fees and court filing costs
- Travel, meals, and lodging when you need to travel away from home for the adoption
- Home study fees for the mandatory household assessment
Two categories of spending are disqualified no matter what. Any expense incurred in violation of federal or state law is out. So is anything already reimbursed by a government program at any level, because Section 137 is designed to cover genuine out-of-pocket or employer-funded costs, not to stack on top of other public subsidies.
When You Can Actually Take the Exclusion
The timing depends on whether you are adopting a U.S. child or a foreign child, and this is where most people get caught off guard.
Domestic Adoptions
For a U.S. child, you exclude employer-provided benefits in the year your employer pays them, whether or not the adoption is final yet. If your employer reimburses $5,000 in 2026 while the adoption is still in progress, you exclude that $5,000 on your 2026 return.
The exclusion also survives a failed adoption. If you attempt to adopt a U.S. child and the process falls through, employer benefits you already received still qualify.
Foreign Adoptions
Foreign adoptions follow a stricter rule. You cannot exclude any employer-provided benefits until the tax year the adoption becomes final. If your employer pays benefits in 2025 for a foreign adoption that does not finalize until 2027, those 2025 payments go into your taxable income for 2025. On your 2027 return, you claim the exclusion for all benefits paid across all the prior years, up to the lifetime cap.
That gap can create a real cash-flow problem. Keep careful records of every payment and the year it was made so you can reconstruct the numbers when the decree finally issues.
What Your Employer’s Plan Has to Look Like
The exclusion only works if your employer runs a qualifying adoption assistance program. A one-off check from the company does not count. The program has to be a separate written plan established for the exclusive benefit of employees.
The plan must meet nondiscrimination rules. It cannot favor highly compensated employees in either eligibility or benefit levels, and no more than 5% of total benefits paid in a given year can go to employees who own more than 5% of the company. The employer also has to give reasonable notice of the program to eligible employees and require participants to substantiate expenses with receipts and other documentation.
Even though the benefits are excluded from your taxable wages, your employer still reports the total on your Form W-2 in Box 12 using Code T. That reporting is how you reconcile the exclusion on your return and how the IRS verifies the benefits came through a qualifying plan.
Claiming the Exclusion
You claim the exclusion on IRS Form 8839, Qualified Adoption Expenses, attached to your Form 1040. Start with the amount in Box 12, Code T of your W-2, then work through the form’s application of the per-child limit and the MAGI phase-out.
If your employer provided more than the exclusion maximum, the excess is taxable and gets added back to your income on Form 1040. Form 8839 handles the math, but it helps to know why your W-2 Code T figure can be higher than the amount you ultimately exclude.
Using the Exclusion With the Adoption Tax Credit
Section 137 is not the only federal tax benefit for adoption. The Section 23 adoption tax credit provides a separate dollar-for-dollar reduction in your tax liability for qualified adoption expenses you pay out of pocket. You can use both the exclusion and the credit for the same adoption, but not for the same dollars.
In practice, you subtract employer-provided benefits from your total qualified expenses first, then apply the credit to whatever is left. On a $25,000 adoption where your employer reimbursed $17,670 under a qualifying plan, you would exclude the $17,670 and potentially claim the credit on the remaining $7,330, subject to the credit’s own limits and phase-out.
One boundary worth flagging: self-employed people cannot use the Section 137 exclusion, because it requires an employer-employee relationship and a formal employer plan. The Section 23 credit is still available for your out-of-pocket costs, and for a self-employed adoptive parent it is the primary federal tax benefit.
