Your October child tax credit payment is due to arrive TuesdayPrior to the March 2021 coronavirus relief legislation, a child tax credit of up to $2,000 per eligible child was available to qualifying parents. However, only $1,400 of the child tax credit was refundable. The child tax credit was expanded to $3,600 per child under age six and $3,000 for children ages six to 17. If you already received three child tax credit deposits, then you should expect a fourth on Oct. 15. But while some lawmakers are trying to make the expanded child tax credit permanent, it is currently slated to expire at the end of this year.
