Basics on the CTC

The Child Tax Credit (CTC) is a federal tax credit that helps families with qualifying children reduce their federal income tax liability.

The child tax credit comprises two components:

  • Nonrefundable child tax credit (CTC); and
  • The refundable portion of the CTC, which is the Additional Child Tax Credit (ACTC).

IRS Letter 6419

The IRS is mailing taxpayers an IRS Letter 6419, which confirms the total dollar amount of advanced child tax credit payments the taxpayer received during the 2021 calendar year. These amounts represent an advanced payment of the child tax credit, which is claimed on Schedule 8812 (Credits for Qualifying Children).

The Letter 6419 is important for two main reasons:

  1. Taxpayers should confirm the amount of cash actually received matches the IRS records; and
  2. Use the information reported on LTR 6419 to complete Schedule 8812 (Credits for Qualifying Children).

The advanced child tax credit payments do not increase the CTC amount available to the taxpayer – it is simply an advanced amount.

Sample Fact Pattern for Letter 6419 and Schedule 8812

John is a single-filing taxpayer and has a 13-year-old son. John’s prior year tax return information indicates he is eligible for the CTC for the 2021 tax year.

John received advanced child tax credit payments totaling $1,250 during the 2021 calendar year. John received Letter 6419, which confirms that he received $1,250 in advanced payments.

When John prepares Schedule 8812, he calculates his total child tax credit amount is $3,000. John accounts for the $1,250 already received, which means he is due a net amount of $1,750 of unpaid child tax credit.
