Child Tax Credit Eligibility

Estimate child tax credit eligibility and phaseout based on AGI, filing status, and number of qualifying children.

Results

Base credit (before phaseout): $2,000
Estimated credit after phaseout: $2,000

How to use this calculator

Enter AGI.
Select filing status.
Enter number of qualifying children.
Review base credit and estimated credit after phaseout.

Inputs explained

AGI: Use your adjusted gross income estimate for the year.
Filing status: Phaseout thresholds depend on filing status.
Qualifying children: Number of children eligible for the credit.

How it works

Base credit per child = $2,000. Phaseout reduces credit by $50 for each $1,000 of AGI over the threshold.

Thresholds (simplified): $200k single/HOH, $400k MFJ.

Formula

Base credit = $2,000 × children
Phaseout reduction = $50 per $1,000 over threshold
Estimated credit = max(0, Base − Reduction)

When to use it

Checking if income triggers a child tax credit phaseout.
Estimating credit impact when income changes.
Planning year-end income/withholding with credit in mind.

Tips & cautions

If AGI is below the threshold, the full base credit is shown.
Phaseout is simplified; actual credits depend on detailed rules and refundable portions.
Run multiple AGI scenarios to see sensitivity.
Simplified; does not model refundable portions, detailed eligibility, or partial-year nuances.
Assumes current base credit/thresholds; update for future years if rules change.
Not tax advice; consult a tax professional.

Worked examples

AGI $100k, single, 2 children

Base = $4,000
Below threshold → Credit ≈ $4,000

AGI $250k, single, 1 child

Base = $2,000
Over by $50k → Reduction = 50 × $50 = $2,500
Credit = $0 (fully phased out)

Deep dive

Estimate your child tax credit by entering AGI, filing status, and qualifying children to see base credit and phaseout.

Use it to see if income triggers a reduced credit and plan accordingly.
