I file married joint return. 3 small children. AGI $90000. Why does turbo tax only give me $1500 tax credit per child. Isn’t it $2000?

Yes, it is $2000 per child.    It sounds like you may have received the Child Tax Credit for 2 of the children and one child is listed as an ''Other Dependent'' which is only a $500 credit.   Once the child turns 17, the credit lowers from $2K to $500.    

Review the birthdates and other data entered for your dependent children.   If a child was born in 2024, make sure to indicate the child lived with you ALL YEAR, even if the child was born in December.   See below for items to double-check in TurboTax.  

To qualify, your child must meet all of these requirements:

• Be under age 17 at the end of the tax year
• Is your child, stepchild, foster child, adopted child, sibling, step sibling, half sibling, or a descendant of any of them (for example, a grandchild, niece, or nephew)
• Has their own Social Security number
  • Children with ITINs don't qualify, but may instead be eligible for the $500 Credit for Other Dependents
• Lived with you for more than half the year
• Didn't support themselves (didn't pay more than half their own expenses)
• Is a U.S. citizen, U.S. national, or U.S. resident alien
  • Residents of Canada or Mexico don't qualify
