Why did I lose or receive a smaller child tax credit?

Here’s what HIVE AI had to say about “Why did I lose or receive a smaller child tax credit?”:

Why your child tax credit may be smaller or gone

The most common reasons are:

  • The law changed after 2021. For tax year 2021 only, the credit was temporarily expanded. Starting with tax year 2022, it generally reverted to pre-COVID rules, so many people saw a much smaller credit or refund than they got the year before.
  • Your child no longer qualifies. For the regular child tax credit, the child generally must be under age 17 at the end of the year, be your qualifying child, live with you for more than half the year, and be properly claimed as your dependent. For 2021 only, the age limit was temporarily expanded to under 18.
  • The child did not have the required SSN by the filing deadline. No credit is allowed for a qualifying child unless the child’s taxpayer identification number is included on the return and was issued on or before the due date for filing; IRS guidance also says the child must have a valid SSN for employment to qualify for the CTC.
  • Your income was too high, so the credit was phased out. The credit is reduced once modified AGI exceeds the applicable threshold. For example, the 2021 expanded credit had phaseout thresholds of $150,000 for joint filers, $112,500 for head of household, and $75,000 for single or married filing separately.
  • Your tax return was adjusted by the IRS. A reduced refund can happen because of math errors, an ineligible child claim, or other return adjustments. The IRS lists ineligible credits or deductions as a common reason for a reduced refund.
  • Part of your refund was offset for other debts. Even if you qualified for the credit, your refund can be reduced to pay past-due child support, prior federal tax, certain state tax debts, or some unemployment-compensation debts.

Special 2021 issue

If you are comparing your refund to 2021, that year was unusual. Many families received advance Child Tax Credit payments during 2021, and when they filed the 2021 return they had to reconcile those payments. That could reduce the remaining credit on the return or even create repayment in some cases.

If the credit was previously disallowed

If your Child Tax Credit, refundable Child Tax Credit, Additional Child Tax Credit, or Credit for Other Dependents was previously reduced or disallowed for a reason other than a math or clerical error, you may need to file Form 8862 to claim it again.
