The 2026 Child Tax Credit at a Glance

The Child Tax Credit (CTC) is $2,000 per qualifying child under age 17 for tax year 2026. Of that amount, up to $1,800 is refundable through the Additional Child Tax Credit (ACTC), which means families with little or no federal income tax liability can still receive a refund. The expanded 2021 version with monthly payments and a $3,600 cap has expired and is not in effect for 2026.

For a married couple with three children under 17 and moderate income, the credit is worth $6,000 — a significant number that I remind every parent about during tax season. The credit phases out at higher incomes but does not disappear for the vast majority of working families.

Income Limits and the Phase-Out

The CTC begins phasing out at modified AGI of $200,000 for single filers and $400,000 for married filing jointly. The reduction is $50 for every $1,000 (or fraction thereof) above the threshold. The phase-out is gradual rather than a cliff.

Filing StatusPhase-Out StartsCredit Eliminated (per child)
Single / HOH / MFS$200,000$240,000 (one child)
Married Filing Jointly$400,000$440,000 (one child)

A married couple with two children and $420,000 AGI loses $1,000 of their $4,000 credit ($20 for each $1,000 above $400,000, times 50). At $440,000, the entire credit is gone for two children. Run your projected AGI through the Self-Employment Tax Calculator to see where you land relative to the phase-out.

Pro Tip: The phase-out uses modified AGI, which adds back certain excluded income like foreign earned income. A self-employed family with $390,000 of Schedule C profit and $20,000 of tax-exempt interest sits at $410,000 modified AGI — already inside the phase-out. Forecast your AGI before year-end so you can time income and deductions accordingly.

Who Counts as a Qualifying Child

The IRS applies five tests for a qualifying child:

  • Relationship: Son, daughter, stepchild, foster child, sibling, or descendant of any of these (grandchild, niece, nephew)
  • Age: Under 17 at the end of 2026 (born after December 31, 2009)
  • Residency: Lived with you for more than half the year
  • Support: Did not provide more than half of their own support
  • Citizenship: U.S. citizen, U.S. national, or U.S. resident alien with a valid Social Security number issued before the due date of the return

The SSN requirement trips up families who adopted internationally or whose children arrived late in the year. A child without an SSN by the filing deadline disqualifies the credit for that child — but you can file for an extension and claim the credit once the SSN arrives.

The Refundable Portion: Additional Child Tax Credit

Up to $1,800 per child is refundable through the ACTC. If your tax liability is zero or smaller than the non-refundable portion, you can still receive a refund. The refundable amount equals 15% of your earned income above $2,500, capped at $1,800 per child.

Consider a self-employed parent with one child and $20,000 of Schedule C net profit. The full $2,000 credit exceeds any tax liability, so the non-refundable $200 offsets nothing. The refundable ACTC is 15% of ($20,000 − $2,500) = $2,625, capped at $1,800. The parent receives a $1,800 refund. Lower that net profit with deductions from the Tax Deduction Finder and the refundable calculation shrinks too — so do not over-deduct.

IRS Warning: The refundable portion requires earned income of at least $2,500. A self-employed parent whose Schedule C shows a net loss cannot claim the ACTC for that year, even with prior-year W-2 wages. If your business is borderline profitable, weigh the value of large year-end deductions against the $1,800 per child you might forfeit in refundable credit.

Claiming the Credit as a Self-Employed Parent

The CTC does not care whether you are W-2 or self-employed — it cares about modified AGI and qualifying children. A sole proprietor with two kids and $120,000 net profit claims the full $4,000. A married couple where one spouse freelances and the other has a W-2 combines both incomes on Form 1040 and tests the $400,000 threshold jointly.

File Schedule 8812 to calculate the credit and the refundable ACTC. The IRS holds refunds that include ACTC until mid-February under the PATH Act, so plan cash flow accordingly.

The Bottom Line

The Child Tax Credit delivers $2,000 per child under 17 for 2026, with up to $1,800 refundable. The phase-out starts at $200,000 single and $400,000 married — high enough that most working families receive the full amount. Self-employed parents qualify on Schedule C net profit, and the refundable portion rewards keeping earned income above $2,500. Model your AGI with the Self-Employment Tax Calculator and check your deductions with the Tax Deduction Finder before you finalize your return.
