Child Tax Credit Example for a Family with Two Different Dependents
Taylor and Lee, a fictional married couple filing jointly, support a 9-year-old child and an older parent in 2026. They need to distinguish a potential CTC amount from an ODC amount and from what is actually usable against tax. This is an illustrative 2026 scenario, not personal tax advice.

The planning question behind the numbers
Taylor and Lee, a fictional married couple filing jointly, support a 9-year-old child and an older parent in 2026.
They need to distinguish a potential CTC amount from an ODC amount and from what is actually usable against tax. The filing-status context is Married Filing Jointly, and every tax value uses the 2026 production calculation.
Scenario profile
They need to distinguish a potential CTC amount from an ODC amount and from what is actually usable against tax.
Taylor and Lee, a fictional married couple filing jointly, support a 9-year-old child and an older parent in 2026.
Married Filing Jointly
Prepared inputs, grouped by role
Income and liability
- $185,000 MAGI
- $68,000 taxable ordinary income, $2,000 qualified dividends, and $4,000 net long-term gain
- $500 other nonrefundable credits
- $92,000 earned income
Dependent records
- one selected CTC child with confirmed work-eligible SSN and dependency facts
- one selected ODC dependent with a timely TIN and confirmed dependency facts
Inputs the fictional taxpayer has prepared
The scenario uses the same inputs accepted by the calculator. No deduction, credit, basis amount, or eligibility conclusion is created inside the example.

- 1. Potential CTC$2,200.00
- 2. Potential ODC$500.00
- 3. Credit after MAGI phaseout$2,700.00
- 4. Available tax liability$7,164.00
- 5. Nonrefundable CTC and ODC$2,700.00
- 6. Refundable ACTC$0.00
- 7. Estimated combined federal benefit$2,700.00
Dependent screening establishes potential amounts first. MAGI, available tax liability, and ACTC capacity then determine how much appears in the modeled benefit.
Change one input and watch the consequence
If MAGI is $425,000 instead of $185,000:
Base case versus one changed input

The phaseout is applied to the combined potential credit in whole $1,000 excess units; eligibility facts still need separate confirmation.
Before you use the estimate
- Recreate the example only with records that support your own inputs.
- Keep the same filing status and tax year when comparing the published numbers.
- Change one material input at a time and read the full breakdown.
- Review the stated limitations before using the estimate.
Where this estimate stops
- The example assumes all entered identification and dependency confirmations are correct and does not resolve custody, tie-breaker, residency, Form 2555, or alternative ACTC issues.
- The fictional facts illustrate production logic and do not establish eligibility, filing treatment, or a recommended action for any reader.
