Adoption Tax Credit Calculator 2026

The federal adoption tax credit offsets up to $17,670 of qualifying adoption expenses per eligible child in 2026, with up to $5,120 refundable. Enter your numbers below to calculate the credit available, any phaseout reduction, and the Section 137 employer adoption benefit — with notes specific to LGBTQ+ families and second-parent adoptions.

How the adoption tax credit works

The federal adoption credit under IRC §23 reduces your tax liability dollar-for-dollar for qualifying adoption expenses. Unlike a deduction that merely reduces taxable income, each dollar of credit eliminates one dollar of federal taxes owed. In 2026, the credit has a partially refundable structure: up to $5,120 can produce a refund even if you owe no federal tax; the remaining non-refundable portion offsets actual tax liability and carries forward for up to five years.

What counts as a qualifying adoption expense

Qualifying adoption expenses under §23(d)(1) include reasonable and necessary adoption fees, attorney fees, court costs, travel expenses while away from home (including meals and lodging), and other expenses directly related to and for the principal purpose of the legal adoption of an eligible child. An eligible child is under age 18 at the time of adoption, or physically or mentally incapable of caring for themselves.

Expenses do not include: surrogate parenting expenses, amounts paid in carrying out an illegal arrangement, amounts paid in connection with the adoption of a foreign child unless the adoption is final, or expenses reimbursed by a government program.

Timing: when to claim the credit

Timing rules differ by adoption type:

• Domestic adoption: Expenses paid before the adoption is finalized are claimed in the tax year following the year of payment. Expenses paid in or after the year the adoption becomes final are claimed in the year paid. This can split credits across two tax years.
• Special needs adoption: The full $17,670 credit is claimed in the year the adoption becomes final, regardless of when expenses were paid or how much was spent.
• International adoption: All expenses — regardless of when paid — are claimed in the year the adoption is finalized in the foreign country. Pre-finalization payments are deferred until finalization.

The $5,120 refundable portion

For adoptions finalized in 2026, up to $5,120 of the credit is refundable — meaning you receive that amount as a cash refund even if your federal tax liability is zero. The remainder of the credit (up to $12,550) is non-refundable and can only offset actual tax owed. Any non-refundable portion you can't use in 2026 carries forward for up to five years.

LGBTQ+ families and the adoption credit

Second-parent adoption

Second-parent adoption — where the non-biological or non-adoptive parent in a same-sex couple legally adopts their partner's child — is a domestic non-special-needs adoption for tax purposes. Attorney fees, court filing costs, home study fees (where required by the state), and related legal expenses all qualify. Because second-parent adoption expenses typically run $2,000–$5,000, the credit is often well under the $17,670 cap, but that full amount is still creditable against tax liability for larger adoptions.

One critical point: the child must not yet be legally your child at the time you begin incurring expenses. If your partner already has legal parentage and you are adopting, the expenses you pay to finalize your own legal parentage qualify. Pre-birth expenses tied to a child who is already your biological child do not qualify.

Same-sex couples with employer adoption benefits

If your employer offers an adoption assistance program, benefits you receive are excluded from your income under §137 (up to $17,670 for 2026). Unlike employer health insurance for domestic partners — which is fully taxable as imputed income — employer adoption benefits are tax-free regardless of marital status. This is one of the areas where domestic partnerships and marriages are treated identically.

The interaction with the credit: employer benefits reduce your qualifying expenses for the §23 credit dollar-for-dollar. If your employer pays $15,000 and you had $25,000 in total expenses, your §23 credit is based on $10,000 in expenses — not $25,000. The §137 exclusion and §23 credit cannot both apply to the same dollar.

Foster-to-adopt and special needs determinations

Many LGBTQ+ families build families through foster care and foster-to-adopt, often at lower upfront cost. If the state has determined that the child has special needs — a formal determination by the state (not the IRS) — you qualify for the full $17,670 credit regardless of actual expenses. Special needs determinations typically cover children with physical, emotional, or medical conditions that make adoption without assistance unlikely, children who are racial/ethnic minorities, older children, or children in sibling groups. Your state's adoption caseworker can confirm whether the child's record includes a special needs determination.

Non-finalized adoptions and pre-adoption expenses

LGBTQ+ families sometimes incur significant pre-adoption legal and consulting expenses before a match is made. For domestic non-special-needs adoptions, those expenses are deductible in the year after they're paid — not in the year of finalization — unless finalization happens in the same year. Keep records by tax year; the credit may be split across two or even three returns depending on timing.

Section 137: the employer adoption assistance exclusion

§137 provides a separate benefit from the adoption credit: employer-paid adoption assistance is excluded from your gross income up to $17,670 in 2026. This reduces your taxable income, not your tax liability directly. The tax savings equals the excluded amount × your marginal rate — shown in the calculator output above.

Many LGBTQ+-affirming employers, particularly in tech and finance, offer adoption benefits that cover a significant share of total costs. These programs are one of the key questions to raise during open enrollment and when evaluating job offers. Because surrogacy benefits are taxable (unlike adoption assistance), the §137 exclusion creates a meaningful financial advantage for families choosing the adoption path.

What the calculator doesn't cover

• State adoption credits: Several states offer additional credits or deductions. Oregon, New Mexico, and others have state-level adoption incentives worth researching based on your state of residency.
• Multiple children in the same year: The $17,670 cap applies per eligible child. If you finalize two adoptions in 2026, the maximum credit is $35,340. Add expenses and run the calculator twice.
• Prior-year carryforward credits: If you claimed the adoption credit in 2021–2025 and have unused carryforward, those carry-forwards can be used against 2026 tax liability. Enter your current-year credit only.
• The TCJA and future years: The adoption credit has been subject to various temporary provisions. The 2026 amounts above are confirmed; 2027 will be indexed for inflation.
