Parents who need to understand the specific dollar amounts they can expect for each child on their tax return
Exact credit amounts by child's age
The One Big Beautiful Bill established a two-tier child tax credit system based on age as of December 31st of the tax year. Children under 6 years old receive $3,600 per child, while children ages 6 through 17 receive $3,000 per child. These amounts represent substantial increases from the previous flat $2,000 credit for all qualifying children.
According to IRS Publication 972, the age determination is crucial for credit calculation. A child who turns 6 on December 31, 2026, qualifies for the higher $3,600 credit for the entire 2026 tax year. However, a child who turns 6 on January 1, 2027, receives only the $3,000 credit for 2026.

Single child examples:
Multiple children scenarios:
Consider the Martinez family with three children: ages 4, 9, and 14.
Under the previous system, this family received $6,000 ($2,000 × 3), meaning they gain $3,600 additional credits.
Age bracket comparison and financial impact
How the fully refundable feature works
The new credit structure eliminates previous restrictions on refundability. Under prior law, families needed at least $2,500 in earned income to receive any refundable portion, and the refundable amount was limited to 15% of earnings above $2,500.
Example of refundability impact:
Single mother with no earned income and one 4-year-old child:
Married couple with $30,000 earned income and two children (ages 2 and 8):
Special situations and timing considerations
Birth year impact: A child born any time during 2026 qualifies for the full credit amount based on their age tier. December babies still generate the full annual credit.
Divorce and custody: According to IRS guidance, only the custodial parent (or the parent designated in a divorce decree) can claim the child tax credit. The credit cannot be split between parents.
Foster children and dependents: Qualifying children for the credit include biological children, stepchildren, adopted children, foster children, siblings, and descendants of these relatives, provided they meet age, residency, and support requirements.
Integration with other tax benefits
The enhanced child tax credit works alongside other family-related tax benefits:
What you should do
Calculate your expected child tax credit using the new amounts and consider how this affects your overall tax planning. If you typically owe taxes at filing, the increased credit might result in a refund instead. If you usually receive refunds, expect significantly larger amounts.
For advance payment recipients, update your Child Tax Credit Update Portal preferences to reflect the new credit amounts. The IRS bases advance payments on prior year information, so manual updates ensure accurate monthly payments.
Key takeaway: The 2026 child tax credit provides $3,600 per child under 6 and $3,000 per child ages 6-17, with both amounts fully refundable and representing increases of 80% and 50% respectively from previous levels.

Key Takeaway: Children under 6 receive $3,600 each, children ages 6-17 receive $3,000 each, both fully refundable with no income requirements.

| 3 children | $10,800 | $5,400-$9,600 | $9,000 | $6,000 |

Higher-income families who need to understand how the new amounts interact with income-based phase-outs
Phase-out calculations with new credit amounts
For high-earning families, understanding how the enhanced credit amounts interact with income-based phase-outs is crucial for tax planning. The phase-out mechanism remains the same ($50 reduction per $1,000 of income above thresholds), but the higher credit amounts mean more potential benefit before complete phase-out.
High earner example:
Married couple earning $320,000 with two children (ages 3 and 10):
This family receives $5,600 compared to $0 under the old system, representing significant tax savings.
Complete phase-out income levels
According to IRS guidance, complete phase-out occurs when the credit reduction equals the full credit amount:
For families with one child under 6 ($3,600 credit):
For families with one child ages 6-17 ($3,000 credit):
The higher credit amounts extend the income levels where families retain some benefit, making the credit relevant for more affluent families than before.
Key takeaway: High earners benefit from both larger credit amounts and higher phase-out thresholds, with some families earning over $350,000 still receiving partial credits.
*Sources: One Big Beautiful Bill Act of 2025, IRS Publication 972*
Key Takeaway: Higher credit amounts mean high earners retain more benefit during phase-out, with complete phase-out now occurring at much higher income levels.

Parents whose children are transitioning between age brackets and need to understand timing impacts
Understanding the age 6 transition
The transition from the $3,600 credit (under 6) to the $3,000 credit (ages 6-17) creates a $600 reduction in credit value when children turn 6. However, the timing of this transition depends entirely on the child's age as of December 31st of the tax year.
Timing scenarios for 2026:
Multi-year planning example:
The Thompson family has a child born in March 2020:
Families should plan for this $600 annual reduction in their child tax credit when budgeting for future years.
Key takeaway: Children receive credits based on their age on December 31st, with a $600 reduction occurring when they transition from under 6 to ages 6-17, but no reduction until they turn 18.
*Sources: IRS Publication 972, One Big Beautiful Bill Act of 2025*
Key Takeaway: Children transitioning from under 6 to ages 6-17 see their credit drop by $600 annually, but timing is based on December 31st age.
