Is your child tax credit calculating correctly if your child turned 6 mid-year?

[kimlony]

It's up to 3600 for children under 6. My son turned 6 in April. SO, I'm expecting to see that he would qualify for the 300 for the first 3 months, and then 250 each month after total 3,150. But it's only saying we're eligible for 2,500 total for him for the year.

That would be correct. 

The credit is based on the age of the child on December 31 of the tax year. 

Most all age requirements are based on the last day of the year. 

"Age test - To qualify, a child must have been under age 18 at the end of the year. Increased credit amounts are available for children under age 6 if certain family income tests are met."

No.   It goes by the age of the child at the end of 2021.   They do not calculate up to his birthday.   If your child was 6 or older at the end of 2021, you get a total of $3000 for his child tax credit.    And it is reconciled against the amount of advance payments you received already.

The amount you can still get for him will be shown on line 28 of your Form 1040.
