Adoption Credit Calculator: 2026 Refundable Split

Choose a tax year and enter one child’s eligible claim amounts, MAGI and available tax liability. See the refundable credit, nonrefundable credit used and new carryforward.

This is a general estimate for information only, not tax, legal or financial advice. Real rules have more conditions than a calculator can show, so check the official source below or a qualified professional for your situation.

How it works

This estimates a new credit for one eligible child, assuming eligibility and the claim year have been established. The 2026 ceiling is $17,670, the refundable cap $5,120, and the MAGI phaseout runs from $265,080 to $305,080. The separate 2025 profile uses $17,280, $5,000 and $259,190–$299,190.

Base = min(remaining per-child ceiling, expenses after coordination) Credit = base × (1 − clamped MAGI phaseout fraction) Refundable = min(credit, refundable cap) Nonrefundable used = min(credit − refundable, available tax liability)

The phaseout fraction is income above the starting threshold divided by $40,000, bounded between zero and one. Following Form 8839, phaseout applies before the refundable split. The unused nonrefundable amount becomes a new carryforward. Qualifying special-needs mode uses the remaining ceiling without requiring expenses. No intermediate rounding; dollars display to cents, so a filed return may differ through whole-dollar rounding.

Existing carryforward balances, expiration and the special 2025 relief for older carryforwards are outside scope. For prior amounts, the Form 8839 line 3 instructions use the sum of lines 3 and 6 on the last form filed for this child, before phaseout. Use the credit-limit worksheet to establish available liability.

For co-adopters other than spouses filing jointly, enter your agreed dollar share of the selected year’s per-child ceiling. We subtract your prior ceiling usage from that share before applying expenses and phaseout, following Form 8839 lines 2–6. A negative MAGI has no phaseout reduction.

Worked examples

Full 2026 ceiling with limited tax

With $20,000 eligible expenses, no reimbursements or prior claims, $100,000 MAGI and $4,000 available tax, the credit is $17,670. Of this, $5,120 is refundable, $4,000 is used against tax and $8,550 becomes new carryforward.

Halfway through the 2026 phaseout

With the same expenses and tax but $285,080 MAGI, the credit is $8,835. The refundable part remains $5,120, the nonrefundable part used is $3,715 and no new carryforward remains.

Employer coordination

With $10,000 expenses and $4,000 allocated to employer reimbursement, no prior claims, $100,000 MAGI and $4,000 tax, the 2026 credit is $6,000: $5,120 refundable and $880 nonrefundable.

Frequently asked questions

Is the $5,120 added to the maximum credit?

No. It is the refundable portion within the 2026 maximum. The rest can offset available tax or become nonrefundable carryforward.

Can I use the same expenses for employer exclusion and credit?

No. Complete employer-benefit coordination first. The reimbursement input represents expenses unavailable for this credit; this tool does not calculate the exclusion.

Which adoption expenses qualify, and when?

An eligible child must be under 18 or physically or mentally incapable of self-care. Expenses for adoption of your spouse’s child and surrogate parenting arrangements do not qualify. For an unfinished domestic adoption, generally claim expenses in the following year. Foreign adoption expenses generally wait until finalization. Check the Form 8839 eligibility and timing instructions before entering expenses.

What counts as a special-needs adoption?

Use this mode only for an eligible U.S. adoption finalized in the selected year with the required state or tribal determination. A medical diagnosis alone is insufficient.

Can I claim this when married filing separately?

Generally married taxpayers must file jointly, subject to limited exceptions in the IRS instructions. The calculator assumes you qualify.

Is the carryforward a future cash refund?

The new unused nonrefundable credit can generally carry forward for up to five years. It is not a promised future refund. Older carryforwards require separate year-by-year tracking.
