Child Tax Credit Phaseout Estimator

For informational planning only. Verify eligibility and credit amounts with a tax professional or official IRS guidance.
Examples
- MAGI $402,000, married filing jointly, 2 children → $3,900 credit remaining.
- MAGI $150,000, head of household, 1 child (left blank so defaults to 1) → $2,000 credit remaining.
FAQ
What counts as modified AGI for this estimate?
MAGI typically starts with adjusted gross income and adds back items like foreign income exclusions; consult IRS guidance for your situation.
Why does the calculator default to one child if left blank?
A default keeps the result deterministic with only two required inputs while letting you increase the number if needed.
Does this include refundable Additional Child Tax Credit rules?
No. It focuses on the main credit after phaseout; refundable portions depend on earned income and are not included.
