How old are their children?

"$3,600 in 2021 for each child under age 6. Similarly, for each child age 6 to 16, it’s increased from $2,000 to $3,000. It also provides the $3,000 credit for 17-year-olds."

It's not "to 18" but "under 18."

Are the numbers on lines 4a,b,c   correct ?   

Yes, there are two children ages 14 and 15.

Line 5 says $4000 and not the $6000 that I would expect.

Thanks for your help

Check your Dependent information on Federal Information Worksheet ?  Is the box marked for Not Qualified for Child Tax Credit ?

I had already checked, and no the boxes are NOT checked

Nevermind the math still wouldn't come out right if one was qualified and one wasn't

I am sorry you lost me on that one.  They are both qualified.

Download the worksheet for Line 5 from IRS... see what you come out with.

What is the amount on Line 1  - over $150,000

Is their income too high?

lol  sorry  I was saying never mind my question about the boxes being checked for qualified or not qualified because the math didn't match that being the issue

Form 8812 line 1 is $257071.  I did download the form and worksheet from instructions.  I get hung up on line 9 of the (line 5) worksheet.  $107071 equals how many of the units.  I come up with 100 and there it goes crazy for me.

I can accept that, but please help me with the calculation so that I can explain why to my client.

When you did the worksheet what did you get for line 10?  What did you get for line 7 ?
