How Much Does It Cost to Adopt a Foster Child?

Adopting a child from foster care usually costs between $0 and $5,000 out of pocket, and much of that is reimbursable. Public agencies cover the home study and pre-service training, federal rules let you recover up to $2,000 per child in one-time legal and travel costs, and most children adopted from foster care qualify their families for monthly assistance payments, Medicaid for the child, and a federal adoption tax credit worth up to $17,670 per child in 2026.¹

What You Pay Up Front

When you adopt through a public agency, the home study itself is free. Private agencies charge $1,500 to $5,000 for the same evaluation in non-foster adoptions, but public agencies absorb the cost because their goal is to place children already in state custody.² Pre-service training is also provided at no charge.

The small bills that do fall to you during preparation are mostly medical and administrative. Every adult in the household needs fingerprinting for a criminal background check, which generally runs $50 to $100 per person. Each prospective parent needs a physical exam completed within the past 12 months, and every household member needs a tuberculosis test.²

Legal and Court Costs at Finalization

After a child has been placed with you and you are ready to finalize, court filing fees for an adoption petition generally range from $0 to $400 depending on where you live. Attorney fees for the finalization hearing can range from nothing, if your jurisdiction provides a free attorney for foster care adoptions, up to roughly $1,500. Some families handle the paperwork themselves and skip the attorney fee entirely.

Reimbursement for One-Time Costs

Federal regulations let you get reimbursed for one-time adoption costs, called non-recurring adoption expenses, up to $2,000 per child. Qualifying expenses include attorney fees, court costs, the adoption study, transportation, and reasonable lodging and food when travel is needed to complete the placement. States may set a lower cap, but $2,000 is the federal ceiling, and the federal government reimburses states at a 50 percent matching rate for these payments.³

Two practical steps protect this reimbursement. Sign a non-recurring expenses agreement with your placing agency before the adoption is finalized, and keep original receipts for every expense you plan to submit. Reimbursement is typically processed after the court issues the final adoption decree.

Monthly Adoption Assistance Payments

The biggest ongoing offset comes through the Title IV-E Adoption Assistance Program, which pays a monthly subsidy for a child adopted from foster care who has special needs.⁴ In this context “special needs” does not necessarily mean disability. A child qualifies if the state determines three things: the child cannot return to the birth parents, a specific factor such as age, membership in a sibling group, ethnic background, or a medical or emotional condition makes placement without assistance unlikely, and the agency made a reasonable effort to place the child without offering a subsidy.⁵ Most children adopted from foster care meet this definition.

The monthly amount is negotiated between you and the state agency based on your family’s circumstances and the child’s needs, and it cannot exceed what the child would have received in a foster family home.⁶ A legally binding adoption assistance agreement must be signed by both you and the agency before the court finalizes the adoption. It spells out the monthly payment, the duration of assistance, and any additional benefits such as Medicaid coverage.

How Long Payments Last

Payments generally continue until the child turns 18. Under the Fostering Connections to Success and Increasing Adoptions Act, states have the option to extend payments to age 19, 20, or 21 if the young adult meets one of these conditions:⁷

Attending a secondary or postsecondary educational program
Working at least part-time
Participating in a program designed to promote employability
Unable to meet any of the above due to a documented medical condition

Not every state has opted into the extension, so check the cutoff age in your jurisdiction. Payments also stop early if you are no longer legally responsible for the child or no longer providing financial support.

Medicaid for the Child

A child adopted with Title IV-E adoption assistance is automatically eligible for Medicaid regardless of your family income. The coverage travels with the child: if you move to another state, the child remains eligible for Medicaid in the new state. For children receiving state-funded (non-IV-E) adoption assistance, Medicaid eligibility depends on whether the receiving state extends coverage, and the adoption assistance agreement will specify whether Medicaid is included.

Changing the Amount Later

The monthly amount is not permanently locked in. Federal law allows the agreement to be renegotiated with the consent of both you and the state agency if the child’s circumstances change.⁶ If your child develops new medical, emotional, or behavioral needs after finalization, you can submit a written request to increase the payment, generally supported by documentation from a qualified professional. Some states also offer supplemental reimbursements for expenses not covered by Medicaid or the standard rate, such as respite care.

Are These Payments Taxable?

No. The IRS treats monthly adoption assistance payments as public welfare benefits, so you do not report them on your federal tax return. For purposes of claiming the child as a dependent, the payments count as support from the state rather than from the child, so they do not interfere with the dependency support test.

The Federal Adoption Tax Credit

The federal adoption tax credit reduces your tax bill dollar for dollar, unlike a deduction, which only reduces taxable income. For 2026 the maximum credit is $17,670 per child.¹ If you adopt a child with special needs from foster care, you qualify for the full credit even if you had zero out-of-pocket expenses.⁸ The IRS treats you as having paid the maximum in qualified adoption expenses simply because the child has a special needs determination from the state.

Refundable Portion and Carryforward

Starting in 2025, a portion of the credit is refundable, meaning you can receive it as a cash payment even if you owe no federal income tax. For 2026, up to $5,120 of the credit is refundable.¹ The rest is non-refundable: it can bring your tax liability down to zero but will not generate a refund on its own. If the non-refundable portion exceeds your tax in the year you claim it, you can carry the unused amount forward for up to five years.⁹

Income Limits

For 2026, families with a modified adjusted gross income below $265,080 can claim the full credit. The credit phases out gradually between $265,080 and $305,080 in MAGI, and families earning above $305,080 cannot claim it.

How to Claim It

Claim the credit by completing IRS Form 8839 and attaching it to your federal tax return.⁹ For a special needs adoption, you will need documentation of the state’s determination. Acceptable proof includes:

An adoption assistance or subsidy agreement from your state
A certification from your state or county welfare agency verifying the child has special needs
An official letter on government letterhead confirming the determination

You will also need the child’s Social Security number, adoption taxpayer identification number (ATIN), or individual taxpayer identification number (ITIN) to complete the form.⁹ Keep your adoption documentation with your tax records.

Employer Adoption Benefits

If your employer offers an adoption assistance program, you can exclude up to $17,670 in employer-provided reimbursements from your taxable income for 2026. The exclusion applies to the same categories the credit covers: attorney fees, court costs, travel, and related expenses. You cannot claim both the credit and the employer exclusion for the same dollar of expense.⁹

When your total qualified expenses exceed what your employer reimburses, you can apply the credit to the unreimbursed portion. If you paid $10,000 in qualified expenses and your employer reimbursed $4,000, you would exclude the $4,000 from your income and claim up to $6,000 as a credit. On Form 8839, calculate the employer exclusion in Part III before figuring the credit in Part II.⁹ For a special needs foster care adoption with no out-of-pocket expenses, the full credit remains available even if you also received employer benefits, because the IRS treats you as having paid the maximum in qualified expenses regardless of actual spending.⁸
