Child tax credit calculator: estimate 2025 CTC, ACTC, and the Credit for Other Dependents

A child tax credit calculator is only useful if it separates the non-refundable child tax credit from the refundable additional child tax credit and uses the current IRS 2025 limits.

What this child tax credit calculator is estimating

For the 2025 tax year, the IRS says the child tax credit is worth up to 2,200 per qualifying child, with up to 1,700 per qualifying child potentially refundable through the additional child tax credit if you meet the earned-income rules. The IRS also lists a separate Credit for Other Dependents of up to 500 for eligible dependents who cannot be used for the CTC or ACTC.

Those pieces are related, but they are not interchangeable. The regular child tax credit and ODC first reduce federal income tax liability, while the ACTC is the part of the CTC calculation that may still create a refund when not all of the credit can be used against tax owed. The calculator shows all three pieces so a family can understand the non-refundable and refundable split instead of seeing only a single headline number.

How the 2025 phaseout and ACTC rules work

The full 2025 Child Tax Credit and Credit for Other Dependents generally begin to phase out above 200,000 of adjusted gross income for single, married-filing-separately, and head-of-household filers and above 400,000 for married filing jointly. Above those thresholds, Schedule 8812 rounds the excess income up to the next 1,000 increment and reduces the combined CTC and ODC pool by 5% of that rounded amount, which is the same as 50 per 1,000.

If part of the credit remains after phaseout but your tax liability is too low to use all of it as a non-refundable credit, Schedule 8812 may allow some of the unused child-credit amount to become refundable as the ACTC. For 2025, the refundable amount is limited to 1,700 per qualifying child and is also limited by 15% of earned income above 2,500. The calculator shows those caps side by side so you can see what is actually controlling the estimate.

Maximum CTC = qualifying children x 2,200

Uses the IRS 2025 maximum Child Tax Credit amount per qualifying child under age 17 with the required Social Security number.

Maximum ODC = other dependents x 500

Adds the non-refundable Credit for Other Dependents for eligible dependents who cannot be used for CTC or ACTC.

Phaseout reduction = ceil(max(0, AGI - threshold) / 1,000) x 50

Applies the standard phaseout above 200,000 or 400,000, depending on filing status.

Estimated ACTC cap = min(unused allowed credit, qualifying children x 1,700, 15% x max(0, earned income - 2,500))

Combines the main refundable limits that matter in a simplified Schedule 8812 planning estimate.

Why the calculator asks for more than income and children

Competitor child tax credit calculators often ask for filing status, income, qualifying children, and sometimes other dependents, but many stop before explaining why tax liability and earned income change the refundability result. This calculator asks for both because the non-refundable CTC and ODC need tax liability to offset, while the refundable ACTC needs earned income above the IRS floor.

That is also why two families with the same number of children and the same adjusted gross income can see different results. One family may have enough tax liability to use most of the credit as a non-refundable amount; another may depend on the ACTC rules and the earned-income cap to recover part of the unused child credit.

Worked example: two qualifying children and moderate tax liability

Suppose a single filer has two qualifying children, 120,000 of adjusted gross income, 85,000 of earned income, and 2,500 of federal tax liability before child credits. The maximum 2025 child tax credit starts at 4,400, and there is no phaseout because AGI stays below the 200,000 threshold.

The first 2,500 of that amount can be used as a non-refundable child tax credit against tax liability. The remaining 1,900 may still be available as an ACTC estimate because earned income above 2,500 is large enough to support the refundability cap, and the per-child ACTC cap is 3,400 for two children. In that scenario, the combined estimated benefit remains 4,400, but it is split between a non-refundable reduction and a refundable amount.

Credit for Other Dependents in this estimate

The ODC can matter when a dependent is age 17 or older, has a taxpayer identification number instead of the required Social Security number for CTC, or otherwise qualifies as a dependent but not as a qualifying child for CTC. The IRS describes the ODC as non-refundable, so it can reduce federal income tax liability but cannot by itself create an ACTC refund.

This page includes other dependents in the combined pre-phaseout credit pool and then limits the refundable portion to qualifying children. That mirrors the practical Schedule 8812 structure better than a child-only calculator while still keeping the tool narrow enough for planning rather than full return preparation.

Eligibility checks the calculator does not decide

The calculator does not determine whether a child is a qualifying child under the IRS dependency, relationship, residency, age, support, citizenship, and Social Security number timing rules. It assumes the entered children already satisfy the Schedule 8812 and Form 1040 requirements for the 2025 tax year.

It also does not model every line interaction on a filed return. Other non-refundable credits, Schedule 3 items, foreign earned income exclusions, Puerto Rico bona fide resident rules, Form 8862 issues after a denied claim, and edge-case Schedule 8812 worksheets can change the real filed amount. Use the result as a planning worksheet, then verify the final credit on the actual IRS forms or with a tax professional if the return is complex.

Further reading

Planning around the refund timing

The IRS says refunds that properly claim ACTC cannot be issued before mid-February. That timing rule can affect cash-flow planning even when the calculator shows a refundable amount, because the whole refund can be held until the statutory delay clears.

For a quick estimate, use the calculator result to understand the likely CTC, ODC, and ACTC split. For filing, compare the result with Schedule 8812, your Form 1040 tax liability line, and any tax software or preparer worksheet that has your complete return.

Frequently asked questions

What is the difference between the Child Tax Credit and the ACTC?

The Child Tax Credit first reduces federal income tax liability. The Additional Child Tax Credit is the refundable part that may still be available when you qualify for the CTC but cannot use all of it against tax owed. The ACTC has its own caps, including the earned-income rule and the per-child refundable limit.

How much is the Child Tax Credit for 2025?

For the 2025 tax year, the IRS lists the Child Tax Credit at up to 2,200 per qualifying child and the refundable ACTC cap at up to 1,700 per qualifying child, subject to eligibility, phaseout, earned income, and tax-liability limits.

What are the 2025 Child Tax Credit phaseout thresholds?

For 2025, the full credit generally begins to phase out above 200,000 of adjusted gross income for single, married-filing-separately, and head-of-household filers and above 400,000 for married filing jointly. The credit is reduced by 50 for each 1,000, or part of 1,000, of income above the threshold.

Why does this calculator ask for tax liability and earned income?

Those inputs help separate the non-refundable and refundable parts of the estimate. Tax liability affects how much of the regular child tax credit and ODC can be used directly, while earned income matters for the ACTC cap because the refundable amount is limited by 15% of earned income above 2,500.

What is the Credit for Other Dependents?

The Credit for Other Dependents is a non-refundable federal credit of up to 500 for eligible dependents who cannot be used for the Child Tax Credit or ACTC. It may apply to some older children, relatives, or dependents with a qualifying taxpayer identification number, but it cannot create a refund by itself.

Can I claim both the Child Tax Credit and the Credit for Other Dependents for the same person?

No. Schedule 8812 separates qualifying children used for CTC or ACTC from dependents used for ODC. Do not count the same dependent in both inputs.

Does a child need a Social Security number for the Child Tax Credit?

Yes. For 2025, the IRS requires the qualifying child to have a valid Social Security number issued before the due date of the return, including extensions, to claim the CTC or ACTC for that child.

Why might the calculator show less than the full credit?

The common reasons are AGI above the phaseout threshold, too little tax liability to use the non-refundable credit, earned income too close to or below the 2,500 ACTC floor, or the 1,700 per-child ACTC cap.

Can the Additional Child Tax Credit increase my refund?

Yes, when you qualify and the Schedule 8812 limits allow it. The ACTC is the refundable portion of the child credit calculation, so it may increase a refund even when federal tax liability is already reduced to zero.

Does this calculator guarantee the amount I can claim on my return?

No. It is a planning estimate built around the main 2025 IRS thresholds and refundability caps. Final eligibility still depends on the full qualifying-child rules, Social Security number timing rules, Schedule 8812 instructions, and the rest of the tax return.
