Adoption Tax Credit: Rules, Eligibility, and How It Works

Adopting a child requires massive emotional and financial commitment. You spend months filling out paperwork, attending meetings, and paying varied fees to bring your child home. 

Fortunately, the federal government provides a helpful mechanism that can offset those costs: the adoption tax credit. But it can be tricky to understand, meaning getting the adoption tax credit explained clearly is a must if you want to plan your finances and file your return correctly.

If you want to understand how adoption affects taxes, you need to start by learning the federal adoption tax credit rules. In this guide, we break down the eligibility requirements, the types of expenses that count, and how different adoption paths change your tax situation.

What Is the Adoption Tax Credit?

The adoption tax credit helps eligible taxpayers offset qualified adoption expenses. It directly reduces your federal tax liability, dollar for dollar. If you owe the IRS $6,000 at the end of the year and you claim a $4,000 credit, your tax bill drops to $2,000.

If you adopt an eligible child, you may be able to claim the Adoption Credit or use income exclusion for employer-provided adoption benefits. 

Qualified adoption expenses are capped at $17,280 per child for tax years starting in 2025. Both the credit and the exclusion cover international, domestic, private, and public foster care adoptions. 

Also starting in tax year 2025, up to $5,000 of the Adoption Credit is refundable, meaning you could get that portion back even if you don't owe federal tax. The rest of the credit is non-refundable (you can only use it to bring your tax bill down to zero). Any unused non-refundable portion can be carried forward for up to five years, but nothing beyond that. If it’s left after five years, you lose it.

Who Qualifies for the Adoption Tax Credit?

Your eligibility will depend on a few specific factors surrounding your family, your income, and the timing of your adoption. You qualify if you adopt an eligible child and pay qualified out-of-pocket expenses.

An eligible child must be under 18 at the time of adoption. If the individual is 18 or older, they must be physically or mentally incapable of caring for themselves.

If you’re in a state that recognizes second-parent adoption (where one partner in a domestic partnership or civil union adopts the biological or legal child of the other partner), you may qualify for the adoption tax credit. This is because the law treats the adoption as creating a new legal parent-child relationship, which is eligible for the credit.

However, if you’re married and adopting your spouse’s child (like in a stepparent adoption), you cannot claim the adoption tax credit. The IRS specifically excludes expenses related to adopting a spouse’s child because the child is already considered part of the family unit for tax purposes. 

Essentially, the credit is designed to help with the costs of bringing a new child into the family, not formalizing an existing relationship with a stepchild.

The timing of your expenses also heavily dictates when you claim the credit. If you adopt a child from within the United States, you can often claim expenses the year after you pay them, even if the adoption never finalizes. 

A failed domestic adoption still yields tax benefits. You simply claim the expenses the year following the payment. If the domestic adoption finalizes, you claim the expenses in the year of finalization.

Documentation Required for the Adoption Tax Credit

To figure out your exact credit and income exclusion, you’ll need IRS Form 8839. This form lets you determine both the adoption credit and any employer-provided adoption benefits you can exclude from your taxable income. 

While you can claim both the exclusion and the credit for the expenses of adopting an eligible child, you cannot claim both benefits for the same expenses. Part II of Form 8839 is for figuring the nonrefundable credit, and you’ll report any refundable credit on your main tax form. This process and the right documentation help you maximize the tax benefits available for your unique adoption situation.

What Expenses May Qualify for the Credit?

The IRS requires your costs to directly relate to the principal purpose of adopting an eligible child. You cannot claim everyday living expenses or costs indirectly tied to the adoption.

Qualified expenses generally include adoption fees, court costs, attorney fees, and traveling expenses. Traveling expenses encompass transportation, meals, and lodging while you travel away from home for the adoption.

You cannot claim expenses paid by someone else. If your employer reimburses you for $5,000 of your adoption fees through an employer adoption assistance program, you exclude that $5,000 from your qualified expenses. You also cannot claim expenses funded by a local, state, or federal grant.

How Income Limits May Affect the Adoption Credit

Your income dictates how much of the credit you can legally claim. The IRS establishes specific income thresholds based on your Modified Adjusted Gross Income (MAGI). 

If your MAGI falls below the initial threshold, you claim the full credit amount tied to your eligible expenses. As your income rises above that first threshold, the amount of the credit you can claim slowly decreases. The IRS calls this a phaseout.

These income thresholds change every single year to account for inflation. For 2025, that MAGI is $259,190 or less; the credit is available, but reduced, if your MAGI is between $259,191 and $299,189). That said, you must check the specific limits for the tax year you plan to claim the credit.

How the Credit Works If You Cannot Use It All

Because the adoption tax credit is non-refundable up to $5,000, you might have more credit than tax liability in a single year. The IRS allows you to carry the leftover credit forward to future tax years.

You can carry the unused portion of your credit forward for up to five years. You apply the remaining credit to your tax liability in year two. If you still have credit left, you apply it in year three. You repeat this process until you use the entire credit or the five-year limit expires.

This mechanism protects middle-income families who incur massive adoption costs but do not generate enough annual tax liability to absorb the credit all at once.

How Adoption Type Can Change Credit Eligibility

The rules shift depending on the specific type of adoption you pursue. The IRS treats domestic, international, and special needs adoptions differently.

A domestic adoption involves a child who is a citizen or resident of the United States. You track your expenses and claim them based on when you pay them and when the adoption finalizes. As mentioned earlier, domestic adoptions allow you to claim expenses even if the adoption fails.

An international adoption involves a child who is not a citizen or resident of the United States. The rules here are much stricter. You cannot claim any expenses until the adoption becomes final. A failed international adoption provides zero tax benefits. If you pay $15,000 to an international agency in year one, but the adoption does not finalize until year three, you wait until year three to claim the credit.

A special needs adoption comes with a highly specific IRS definition. The state child welfare agency must determine that the child cannot or should not be returned to their parents' home. The state must also determine that the child probably will not be adopted unless the government provides assistance to the adoptive family.

If you finalize the adoption of a U.S. child with special needs, the IRS allows you to claim the absolute maximum credit amount, regardless of your actual out-of-pocket expenses. You might pay $0 in adoption fees because you foster-to-adopt through the state system. You still claim the full maximum credit simply because the state declared the child special needs.

Understanding How the Adoption Tax Credit Fits Your Situation

Your tax situation is entirely unique to your family's timeline, income, and expenses. Applying the federal adoption tax credit rules requires you to map out exactly what you spent and when you spent it.

First, determine your child's eligibility. Verify their age and status (ie, not a stepchild). Next, categorize your adoption type. Identify whether you pursued a domestic infant adoption, an international adoption, or a state foster care adoption.

Gather your receipts. Tally your agency fees, lawyer bills, court filing fees, and travel costs. Subtract any amounts reimbursed by your employer or funded by government grants.

Check your income against the IRS phaseout limits for the current tax year. If your MAGI sits below the phaseout, you move forward with your full expense total. If you fall in the middle of the phaseout range, you calculate your reduced credit amount.

Finally, compare your allowed credit against your total tax liability for the year. If the credit exceeds your liability, prepare to track your carryforward amount for the next five years.
